Level 1 lifecycle of each product from the bank’s point of view, with treasury and the investment firm as a single entity. Columns are the parties, rows the phases from pre-trade to maturity; numbered steps are messages, deliveries or payments between them, with the channel or infrastructure in the pill. Hover a step for the detail, click it or use the walkthrough to be taken through the diagram step by step. Where a product has distinct routes (voice or electronic, bilateral or cleared, gross or CLS), the lettered routes show them side by side. The Inside the Bank section covers the same flows from inside the bank, team by team and system by system. UK market conventions throughout; all numbers illustrative. New to this? Begin with Start here. This is the United Kingdom version of the sell-side page: the bank is authorised by the PRA and supervised with the FCA, its markets division outside the ring-fenced retail bank, the home market products settle at CREST and the ICSDs and clear at LCH Ltd, ICE Clear Europe or Cboe Clear Europe with the cash through CHAPS, the government market is the DMO’s gilt market, settlement is T+2 until October 2027 (gilts already T+1), and the global products (FX, commodities, US credit and mortgages) keep their own infrastructure; each product opens with a UK note on what differs from the US page, which the US flag reaches at the same product.

How the diagrams work, the lifecycle common to all 62 products, a map of the products and of the views inside the firm, the facts table and a glossary, with the local terms at the end.
Currencies trade over the counter, GBP on one side of nearly nine trades in ten. The bank quotes off the interbank market, deals, then hedges or warehouses. Spot and forwards settle gross or in CLS; everything beyond spot is a swap under US rules and is reported to a trade repository; options add premium and expiry events; prime brokerage lets a fund trade with many dealers on the bank’s credit, every trade given up to the bank.
Pre-tradeThe client asks for a price by voice or sees a streaming one; the bank prices off the interbank market and adds a margin.
ExecutionDone in seconds; the bank hedges in the market or keeps the risk against opposite client flow.
Post-tradeConfirmations by SWIFT or on the venue; forwards, swaps, NDFs and options are reported to the trade repository.
SettlementEach currency moves on its own payment system (gross) or both together in CLS (payment versus payment).
Life and maturityForwards and options are marked daily until the value date or expiry; collateral moves under a CSA; options are exercised or lapse.
The short end of the market, where the bank funds itself and where clients place cash. UK Treasury bills, sterling commercial paper and certificates of deposit are discount or short-coupon instruments settling same day or T+2 through CREST or CREST’s money market program; the overnight rate and repo are the overnight markets that balance the bank’s account at the central bank; securities lending is the stock-borrow side of the same desks.
Pre-tradeRates are quoted in discount or money-market yield; treasury sets the bank’s own funding curve; brokers show the overnight rate and repo levels.
ExecutionTrades are done in the morning for same-day settlement; the bank is dealer (bills, CP), issuer (CDs, deposits) or borrower (the overnight rate, repo).
Post-tradeConfirmations by MT320 or platform; the Bank of England’s Sterling Money Market Data collection report for the overnight rate; sponsored repo submitted to LCH Ltd; CP created by the issuing and paying agent.
SettlementSame day: bills on CREST, CP and CDs through the ICSDs’ same-day settlement, the overnight rate by CHAPS, repo bilateral, triparty at BNP Paribas Securities Services or through LCH Ltd.
MaturityDays to months later: par repaid, cash and collateral returned, and most of it rolled into the next trade.
Derivatives on interest rates. Standard swaps are traded on MTFs and OTFs and cleared at a CCP; swaptions, caps and floors stay bilateral under the ISDA; FRAs fix a single period; futures run through the bank as clearing broker; inflation swaps add the CPI to the lifecycle; cross-currency basis swaps exchange principal in two currencies and stay bilateral; xVA covers the counterparty, funding and capital costs of uncollateralized trades. The bonds themselves are under Fixed Income.
Pre-tradeRequest for quote on an MTF or OTF or by voice; the bank prices off its curve, the vol surface and the interdealer screens.
ExecutionSwaps trade in rate, options in volatility, futures on the exchange; the bank hedges its DV01 with gilt futures or interdealer swaps and its vega in the options market.
Post-tradetrade repository report for every swap; electronic confirmation on Markitwire; novation to the CCP for cleared products.
Clearing and settlementCleared swaps and futures live at the CCP with initial and variation margin; bilateral trades exchange premium and collateral under the CSA.
Life and maturityFloating resets, fixings, caplets and settlements; daily margin, compression, rolls; inflation swaps re-index with each CPI print.
Bonds and the credit derivatives on them. gilts settle delivery versus payment on CREST and net at LCH Ltd, with inflation-linked gilts adding the CPI; corporate bonds are made out of dealer inventory, printed on the APA and settled at CREST on T+2; new issues are born through a one-day bookbuild; index CDS are cleared, single names bilateral; leveraged loans settle by assignment through the agent bank with no depository at all; sub-sovereign bonds are the public sector market, sold by competitive or negotiated sale and reported to the FCA instead of the FCA.
Pre-tradeRFQ to several dealers on Tradeweb, MarketAxess or Bloomberg, an auction bid or a bid list; the bank quotes in yield or as a spread over gilts from its inventory and axes.
ExecutionDone on the platform or by voice; the bank hedges rates with gilt futures and spread risk with CDS, or runs it.
Post-tradethe APA print within minutes; allocation and matching through CTM; CDS confirmed on MarkitSERV and reported to the trade repository or the trade repository.
Settlementgilts DVP on CREST, corporates and sub-sovereign bonds DVP at CREST, on T+2; index CDS novated to ICE Clear Credit; loans by assignment through the agent, days to weeks later.
Life and maturityCoupons through CREST or CREST; inflation-linked gilts re-index with the CPI; CDS pay quarterly and roll twice a year; loans pay through the agent.
Bonds backed by pools of loans. Agency MBS trade as TBAs (a US market), forward contracts on generic pools, netted at LCH Ltd CREST with pools announced 48 hours before a monthly settlement on CHAPS; specified pools trade by ISIN at a payup; agency CMOs re-cut pools into tranches with different prepayment profiles; ABS and CMBS are structured by the bank, placed with investors, born at CREST and then run monthly through servicer and trustee.
Pre-tradeTBAs (a US market) are quoted off the interdealer screen; pools and tranches are analyzed loan by loan and bid on lists as a payup or a spread to swaps.
ExecutionForward trades for TBAs (a US market) with a monthly settlement date; cash trades for pools and tranches; the bank hedges duration and sells TBA against pools.
Post-tradeTrade report; TBAs (a US market) netted at LCH Ltd CREST with daily variation margin; new issues priced and allocated, then closed into CREST.
SettlementAgency MBS on CREST after pool notification; non-agency ABS and CMBS at CREST on T+2, with a factor applied.
Life and maturityMonthly factors and remittances: the servicer collects, the trustee pays the waterfall; prepayments and losses are watched against the model.
Stocks and the derivatives on them. Cash equities trade on the London Stock Exchange, the MTFs and the systematic internalisers, net at the CCP and settle at CREST on T+2; listed options clear at ICE Clear Europe and index futures at ICE Futures Europe, with the bank as broker, market maker or clearing broker; OTC options, variance swaps and total return swaps are bilateral, reported to the FCA’s repositories; ETFs are created and redeemed by the bank as authorized participant; convertibles are credit plus an equity option traded against a stock hedge; structured notes are the bank’s own debt with an option inside, sold through distributors.
Pre-tradeOrders arrive by FIX from the client’s system or by voice for blocks; pre-trade risk checks run on every order; OTC products are quoted off vol surfaces.
ExecutionAlgorithms slice orders across exchanges and dark pools, or the bank prints a block as principal; listed derivatives match on the exchange and clear at ICE Clear Europe or ICE Futures Europe.
Post-tradeTape and transaction reporting reporting; allocation and matching through CTM matched under the T+1 code’s allocation and confirmation practices; OTC derivatives reported to the FCA’s security-based swap repository.
SettlementStocks and ETFs net at the CCP and settle at CREST on T+2; options and futures live at the clearing house with daily margin; OTC trades exchange premium and collateral.
Life and maturityDividends and corporate actions through CREST; daily margin and delta re-hedging; expiry, exercise, resets and terminations.
Energy and metals, financial and physical. The bank writes commodity swaps for producers and consumers and hedges them in futures; as clearing broker it clears clients’ NYMEX and ICE futures, which end in physical delivery unless closed; gold trades like a currency and settles as a book entry in London or as identified bars.
Pre-tradePrices come from the futures curve (NYMEX, ICE, COMEX) and the physical market; swaps are quoted as a strip, metals in USD per ounce.
ExecutionSwaps by voice or chat with the bank as counterparty; futures on the exchange with the bank as clearing broker; the bank hedges swaps in futures.
Post-tradeISDA commodity confirmations and trade repository reports for swaps; clearing at CME for futures; MT600 confirmations for metals.
SettlementSwaps settle in cash against the monthly average; futures by daily variation margin; gold as unallocated book entry in London or as allocated bars.
Life and maturityMonthly settlements and hedge rolls; position limits as expiry nears; physical delivery for futures held through the last trading day.
The same flows seen from inside the bank: who does what, in which system, in what order. The views follow a trade through the bank. Front to Back is the map. The foundations come first: the client, the instrument and the product must exist before anything trades. The front office prices the trade and manages the risk; operations confirms, clears, settles, margins and funds it; two client businesses, futures clearing and prime brokerage, run on that machinery; the control functions watch all of it and report to the regulators. Columns are the bank’s own teams, with the outside world at an edge; the pills name the systems.
FoundationsClient onboarding, reference data and new product approval: the client, the instrument and the product exist and are approved before a trade can be booked. Systems: client master, security master, model inventory.
Front officeSales covers the client and quotes; trading makes prices, hedges and owns the P&L; the pricing engine quotes at scale. Systems: market data platform, pricing library, trade capture.
OperationsTrade support confirms and reports; settlements, clearing and custody move and hold the securities; collateral and cash management fund the positions. Systems: confirmation and settlement systems, SWIFT gateway, collateral system, payment hub.
Client businessesThe bank as clearing member and as prime broker: execution, clearing, margin, financing and stock borrow for clients, on the same operations. Systems: clearing broker clearing system, PB portal, margin engines.
ControlIndependent of the desk: limits and exposure, official P&L and valuation, surveillance, and the reports to the regulators from real-time trade reports to periodic returns. Systems: risk engine, P&L and ledger, surveillance, reporting hub.
How to read a diagram
Columns are the partiesThe client on the left, the bank (treasury and investment firm as one) next to it, then the market the bank hedges in, then the infrastructures: clearing houses, depositories, payment systems, trade repositories. In the Inside the Bank section the columns are the bank’s own teams instead, with the outside world at an edge.
Rows are the phasesTime runs down the page: pre-trade, execution, post-trade, clearing and settlement, life of trade, maturity. The band label gives the timing (T is trade date, T+2 the next business day).
Arrows are stepsNumbered in order. Solid arrows are messages, deliveries or payments; dashed ones are standing flows like price streams; two-headed ones are exchanged or matched; dotted with a hollow badge are optional. Boxes on a lifeline are things a party does internally.
Pills are the channelAmber for voice and chat, blue for electronic platforms, rose for SWIFT messages, grey for infrastructure systems, teal for market data, lavender for the bank’s internal systems. Each pill shows a one-line definition on hover.
Figures are the worked exampleThe short figures under the arrows follow one illustrative trade through the lifecycle; the strip above the diagram summarizes it. Hovering a step shows the full detail; clicking it opens the walkthrough.
Letters are routesWhere a product can go two or three ways (voice or electronic, gross or CLS, bilateral or cleared, bilateral or triparty repo), the lettered, colored steps show each route; black numbered steps are shared.
A product can be read two ways: scroll the diagram and hover for detail, or press Walk through the steps above any diagram to follow it one step at a time, with the detail in a card. The arrow keys move forward and back.

Each product is a variation of this sequence: a price, a trade, an agreement on the facts, an exchange of value, and the maintenance of the position until it ends. What changes is who sits in the market infrastructure column, how long each phase takes, and which phases a product skips.

Inside the bank, 14 views
The same flows seen from the bank’s own teams: who does what, in which system. Front to Back is the map; the foundations (client, instrument, product) come before any trade; the front office prices and hedges; operations confirms, clears, settles, margins and funds; the futures and prime brokerage businesses run on that; the control functions watch all of it.
Where each product trades, clears, settles and is reported
The same five questions for every product. Cleared means a clearing house stands between the two parties after the trade; the cycle is the gap between the trade and the exchange of value.

Glossary
The terms that come back on every diagram. Every pill in the diagrams also shows its definition on hover.
Concepts
DVP: Delivery versus payment: the security and the cash move at the same moment, so neither party is exposed to the other.
PvP: Payment versus payment: both currencies of an FX trade settle together, which is what CLS does.
CCP: Central counterparty or clearing house: steps between buyer and seller after the trade, guarantees both sides and collects margin.
Novation: The legal step by which one trade between two parties becomes two trades with the clearing house in the middle.
Clearing member: A firm that is a direct member of a clearing house and clears for itself and its clients.
ICE Clear Europe: ICE’s London clearing house for the ICE Futures Europe contracts (Brent, gasoil, gilt futures, SONIA futures, FTSE 100 futures and options, the former LIFFE equity options), which cleared European CDS until 2023; the counterpart of the OCC and CME Clearing for the UK listed derivatives.
Clearing broker: The clearing member (a bank or a large investment firm) that clears a client’s exchange-traded and OTC derivatives and repo at the CCPs under UK EMIR’s client clearing rules, with the omnibus or individually segregated accounts; the counterpart of the US FCM.
Initial margin: Collateral posted at the start of a trade to cover the loss if a party defaults and the position has to be closed out.
Variation margin: The daily cash or collateral payment of the change in a trade’s value, so that exposure never builds up.
Haircut: The discount applied to collateral: lending GBP 100 against GBP 102 of bonds is a 2% haircut.
Mark to market: Revaluing a position at today’s market price; the basis for margin calls and the P&L.
Netting: Offsetting all of a firm’s buys and sells of the same thing into one net delivery or payment.
Affirmation: The client’s or custodian’s agreement with the trade details on trade date, required for next-day settlement in the US.
Allocation: Splitting a block trade across the funds and accounts it was executed for, at the average price, under the manager’s allocation policy.
Settlement cycle: The gap between trade date and settlement date: T+2 for US stocks, bonds and gilts; T+2 for most FX spot.
Repo: Repurchase agreement: selling a security and agreeing to buy it back tomorrow at a slightly higher price, which is a secured loan.
Hedge: A trade the bank does in the market to offset the risk it took on from the client.
Warehouse: Keeping a client position unhedged for a while, expecting opposite client flow or a favorable move.
Back to back: Hedging a client trade immediately with an identical opposite trade, so the bank keeps only the margin.
Last look: A dealer’s right to reject a client’s electronic trade request within a short window after it arrives.
ISDA: The master agreement that governs over-the-counter derivatives between two parties; the CSA is its collateral annex.
Custodian: The bank that holds a client’s securities and cash and settles its trades (BNP Paribas Securities Services, State Street, JPMorgan, Northern Trust).
Trade repository: The repository to which every derivative is reported under UK EMIR by both counterparties (DTCC’s UK repository, UnaVista, ICE Trade Vault, Regis-TR UK) and every securities financing transaction under UK SFTR; the FCA supervises them.
Prime broker: The bank that gives a fund financing, stock borrow, one credit line to trade with many dealers, and settles and reports all of it in one place.
Give-up: A trade executed with one dealer and handed to the client’s prime broker, which becomes the counterparty to both sides.
Cross-currency basis: The spread added to the non-GBP leg of a cross-currency swap so that it prices at par; a measure of how expensive GBP is to borrow through the swap market.
REMIC: Real estate mortgage investment conduit: the public sector trust that holds mortgage pools and issues CMO classes against them.
PAC: Planned amortization class: a CMO tranche that pays on a fixed schedule as long as prepayments stay within a band; a support tranche absorbs the rest.
Autocall: A note that is redeemed early at par plus coupon when its underlying index is at or above a set level on an observation date.
Conversion ratio: The number of shares a convertible bond turns into; the conversion price is par divided by that number.
Window forward: An FX forward with a settlement window instead of a single value date: one rate for the whole amount, drawn in parts on any day between the window start and end; priced at the worst forward rate in the window for the client; called a time option forward at the UK and Canadian banks.
Average rate forward: A cash-settled forward on the average of a series of fixings over a period: at the end the difference between the agreed rate and the average is paid on the notional, so it hedges a flow converted regularly over the period rather than on one date.
Average rate option: An option on the average of a series of fixings (an Asian option): the payoff is the difference between the strike and the average if in the money, cash settled after the last fixing; cheaper than a vanilla because the average moves less than the rate on one day.
Forward points: The difference between the forward and the spot rate, quoted in pips: the interest differential between the two currencies over the period; positive (a premium) when the base currency’s interest rate is the lower of the two.
Reserve-based lending: A revolving loan to an oil and gas producer secured on its reserves, with a borrowing base set from the value of the proved reserves at the lenders’ price deck and redetermined twice a year; the credit agreement requires a minimum hedge, caps the hedge volumes and secures the lenders’ hedges equally with the loans.
Costless collar: A bought put and a sold call at strikes chosen so the premiums offset: the producer has a floor and gives up the price above the call; the skew of oil options makes the call strike lower than a symmetrical one.
Three-way collar: A collar plus a sold put below the floor: the extra premium raises the floor or the cap, but the protection stops below the sold put, so the producer is exposed again in a deep price fall.
Calendar month average: The average of the daily settlement prices of the front-month futures over a calendar month (the NYMEX WTI CMA), the reference most oil swaps and options settle on; the options on it are Asian options.
Cap-and-trade: An emissions trading system: the regulator caps the total emissions of the covered sources, issues allowances up to the cap (auctioned or allocated free), and each source must surrender one allowance per tonne it emits; the sources trade the allowances, so the price sets where the reductions are cheapest.
Compliance period: The period at the end of which an emitter must have surrendered allowances for all its covered emissions (three years in California, with an annual partial surrender; one year in the EU and UK systems).
Voluntary carbon credit: A carbon credit issued by an independent standard (Verra, Gold Standard and others) and bought by a company for its own climate claims rather than a legal obligation; the market’s integrity issues led to the Core Carbon Principles and, in the US, the FCA’s 2024 guidance on the listed derivatives.
Forward contract exclusion: The exclusion of a physically settled forward on a nonfinancial commodity from the swap definition when the parties intend delivery, so the contract is outside the swap reporting, clearing and margin rules; a cash-settled contract on the same commodity is a swap.
Liability award: A share-based award settled in cash (a stock appreciation right, a cash-settled RSU, a deferral notionally invested in company stock), remeasured at fair value each period through compensation expense under ASC 718, unlike an equity award expensed at its grant-date value.
Rule 10b-18: The FCA safe harbor for an issuer’s repurchases of its own stock: one broker a day, no purchases at the open or in the last ten minutes, a price no higher than the highest independent bid or last trade, and no more than 25% of the average daily volume; dealers hedging swaps on the issuer’s stock usually apply the same conditions by contract.
Call spread: A bought call and a sold call at a higher strike: the buyer is protected between the two strikes for a premium lower than a single call’s, and exposed again above the higher strike.
Market infrastructure and venues
CHAPS: The UK’s high-value sterling payment system, run by the Bank of England on the RTGS: same-day, irrevocable payments between the banks’ reserves accounts, 06:00 to 18:00, used for the wholesale settlements and the large transfers; the counterpart of Fedwire and T2.
CREST: The UK central securities depository, run by Euroclear UK & International: the book-entry settlement of UK and Irish shares, gilts and money market instruments, delivery versus payment in central bank money for sterling through the Bank of England’s RTGS (T+2 for shares, T+1 for gilts), the stamp duty reserve tax collection and the corporate actions; the CREST settlement banks provide the participants’ cash; the counterpart of DTC and T2S.
CLS: CLS Bank settles both sides of a currency trade at the same moment (payment versus payment) so neither party pays without receiving.
LCH Ltd: The London clearing house of LSEG: SwapClear for interest rate swaps (the largest in the world), RepoClear for gilt and European government bond repo and cash, EquityClear for the London Stock Exchange’s and the MTFs’ equity trades, ForexClear and the £GC products; supervised by the Bank of England; the counterpart of NSCC, FICC and CME Clearing at once.
MBSD: FICC’s Mortgage-Backed Securities Division: clearing and netting for agency MBS TBA trades.
ICE Clear Credit: The main clearing house for credit default swaps.
LCH: London clearing house; LCH SwapClear clears most interest rate swaps in the world.
Triparty: Repo and collateral management where an agent (Euroclear Bank, BNY, J.P. Morgan) holds the collateral, values it, allocates and substitutes it and holds it in the lender’s account; the route for the sterling and international collateral of the banks and the funds.
AURUM: The London bullion clearing system: book-entry transfers of unallocated gold and silver between clearing banks.
APA: An approved publication arrangement: the venue through which an SI or a firm publishes its OTC trades in real time (one minute for a share, fifteen minutes for a bond) with the deferrals the FCA’s transparency rules allow; the UK counterpart of the TRF and TRACE.
FCA register: The Financial Services Register: the public register of the authorised firms, the appointed representatives, the individuals and the venues the FCA and the PRA regulate; the counterpart of BrokerCheck and the ESMA registers.
CTM: DTCC’s Central Trade Manager: matches the broker’s trade details with the client’s and its custodian’s so settlement can happen.
DMO: The Debt Management Office, the Treasury’s agency that issues the gilts and the Treasury bills through auctions, syndications and tenders with the gilt-edged market makers, manages the government’s cash and runs the purchase and sale service for retail investors; the counterpart of the Treasury’s debt management.
MTF: A multilateral trading facility operated by an investment firm or a market operator under UK MiFID: Cboe Europe’s UK books, Turquoise and Aquis for equities, the bond and derivatives platforms (MarketAxess, Tradeweb, Bloomberg) for their UK business; the dark MTFs run without the EU volume caps since 2023.
ECN: Electronic communication network: an anonymous order book where banks trade with each other (EBS, Refinitiv Matching).
Interdealer broker: A broker who arranges trades between dealers anonymously, by voice or screen (TP ICAP, BGC, Tradition).
Traiana: The industry give-up hub (CME Group): an FX trade done with one dealer is matched here and given up to the client’s prime broker.
Parity: The electronic bidding platform for competitive sub-sovereign bond sales; syndicates submit sealed bids to the issuer through it.
Inside the bank: teams and systems
Front office: Sales, trading and structuring: the people who face clients, make prices and take risk, and the systems they trade on.
Middle office: Trade support: checks every booking, matches confirmations and allocations, sends regulatory reports, and resolves the exceptions between the desk and operations.
Back office: Operations: settlements, payments, reconciliations, asset servicing and collateral movements; the teams that make the exchange of value happen.
Product control: The finance team that owns the official P&L and the valuation of the trading books, independent of the desk, and posts them to the ledger.
Three lines of defense: The desk owns its risk (first line); risk, finance and compliance check it independently (second line); internal audit tests both (third line).
STP: Straight-through processing: a trade that flows from execution to settlement with no human touch; the middle office works only the exceptions.
Pre-deal check: The automated credit and limit check run on a quote or order before the trade is done, against the client’s line and the desk’s limits.
Trade capture: The front-office system where every trade is booked and positions, risk and P&L are kept, one per desk family in most banks (Murex MX.3, Calypso, Summit, Bloomberg TOMS, Fidessa, in-house).
Reporting hub: The engine that turns bookings into regulatory reports (UK MiFIR transaction reports, APA reports, UK EMIR and UK SFTR reports, COREP) and tracks acknowledgments and rejects (DTCC Report Hub, AxiomSL, in-house).
ARM: An approved reporting mechanism: the service through which a firm sends its transaction reports to the FCA’s Market Data Processor by the end of T+1; most firms use one rather than connecting directly.
UK SFTR: The onshored SFTR: the reporting of repos, securities loans and margin loans to a UK trade repository by T+1 by the financial counterparties (the UK removed the reporting duty for non-financial counterparties), with the collateral and the reuse; the disclosure of reuse to clients.
Settlement system: The back-office system that turns a trade into settlement instructions, tracks fails and holds the settled positions (Broadridge, the back-office module of Murex or Calypso, in-house).
Nostro reconciliation: Matches the bank’s own cash and securities records against bank and depository statements and works the breaks (SmartStream TLM, Duco, in-house).
Collateral system: Holds every CSA’s terms, computes the daily margin calls, tracks collateral balances, disputes and substitutions (Calypso, Murex, CloudMargin, Acadia).
Margin call cycle: The daily sequence: value the portfolio, compute the call, issue it by the deadline, agree or dispute, deliver the collateral, reconcile.
Cash forecast: Treasury’s projection of the day’s cash in and out by currency, rail and time, built from every settlement system’s expected flows.
Intraday liquidity: Real-time view of the central bank account and nostro balances, payments queued and released, and the day’s peak usage (Planixs Realiti, in-house).
FTP: Funds transfer pricing: the internal rate at which treasury lends to or borrows from each desk, so the cost of balance sheet shows up in each book’s P&L.
ALM system: Asset and liability management: the balance sheet by tenor and liquidity, the buffer, LCR and NSFR projections, interest-rate risk in the banking book (QRM, Moody’s, Finastra).
P&L explain: Breaking the day’s profit into its causes (new trades, market moves by risk factor, carry, fees, valuation adjustments); an unexplained residual is a control failure to chase.
IPV: Independent price verification: product control’s check of the desk’s marks against external sources (the APA, consensus services, dealer quotes) at month end.
Sub-ledger: The accounting record by product and book, fed by the trade and settlement systems, from which the general ledger is posted.
General ledger: The bank’s books of account (SAP, Oracle); the balance sheet, capital and regulatory returns are produced from it.
Surveillance: Monitors orders, trades, chats and calls for market abuse and conduct breaches and raises alerts for compliance (NICE Actimize, the London Stock Exchange SMARTS, Behavox).
Nostro: The bank’s account at another bank in a foreign currency; the central bank account at the Bank of England plays the same role for GBP.
Local terms, rules and institutions
PRA: The Prudential Regulation Authority, part of the Bank of England: the prudential regulator of the banks, the building societies and the insurers (capital, liquidity, ring-fencing, the SREP); an investment firm that is not a bank is the FCA’s alone.
FCA: The Financial Conduct Authority: the conduct regulator of every UK financial firm and the prudential regulator of investment firms, asset managers and the venues; its Handbook (COBS, CASS, SYSC, MIFIDPRU, COLL, MAR) is the rulebook on this page; ESMA’s counterpart and the SEC’s and FINRA’s at once.
Bank of England: The central bank: monetary policy (Bank Rate, set by the Monetary Policy Committee), the reserves accounts and the facilities (the short-term repo facility, the Discount Window Facility), the RTGS and CHAPS, and the supervision of the FMIs (LCH Ltd, ICE Clear Europe, LME Clear, CREST); the PRA sits inside it.
Bank Rate: The Bank of England’s policy rate, paid on all reserves balances (a floor system) and reviewed eight times a year by the Monetary Policy Committee; SONIA trades a few basis points below it.
SONIA: The Sterling Overnight Index Average, the Bank of England’s benchmark from the banks’ overnight unsecured wholesale borrowing (about GBP 50 billion a day), which replaced sterling LIBOR at the end of 2021 and is the reference for the sterling swap market.
UK MiFID: The onshored MiFID II: the authorisation, conduct and organisational rules for investment firms, kept in the FCA Handbook (COBS, SYSC, MAR) and the regulators’ technical standards, with the UK’s own changes since 2021 (no RTS 27 and 28 reports, research bundling allowed again, the SI regime kept).
UK MiFIR: The onshored MiFIR: transparency, transaction reporting (Article 26 through an ARM to the FCA), the SI regime and the trading venue rules, amended by the wholesale markets reforms (the share trading obligation and the dark volume caps removed, a bond consolidated tape coming).
COBS: The FCA’s Conduct of Business sourcebook: client categorisation, the suitability and appropriateness rules (COBS 9A and 10A), best execution (COBS 11.2A), inducements (COBS 2.3A, with the payment for order flow ban), the costs and charges disclosure, the client reporting and the financial promotion rules (COBS 4).
UK EMIR: The onshored EMIR: the clearing obligation for the standard interest rate and credit swaps at a UK or recognised CCP (LCH Ltd, ICE Clear Europe), the margin rules for uncleared derivatives, the reporting of every derivative to a UK trade repository by both counterparties, and the Bank of England’s supervision of the CCPs.
UK CSDR: The onshored CSDR rules for CREST as the UK CSD; the UK did not take the settlement discipline regime, so there are no cash penalties on fails and no mandatory buy-ins, and the exchange’s and the CCP’s rules discipline the fails; T+1 comes on 11 October 2027.
T+1 code: The UK Accelerated Settlement Taskforce’s code of conduct for the move to T+1 on 11 October 2027: the allocation, confirmation and matching practices (confirmation on the trade date, matching by the morning of T+1), the SSI standards and the automation the market agreed to, alongside the EU and Switzerland on the same date.
UK MAR: The onshored Market Abuse Regulation: insider dealing, unlawful disclosure and manipulation, the market sounding regime, the stabilisation safe harbour, the suspicious transaction and order reports to the FCA; the Criminal Justice Act and the Financial Services Act add the criminal offences.
UK short selling rules: The UK short selling regime: the locate requirement before a short sale in shares, the net short position reports to the FCA (at 0.2% of the issued share capital under the 2025 regulations, published in aggregate per company instead of by name), and the FCA’s power to ban or restrict; the onshored SSR until the new regime.
Stabilisation: The purchases an underwriter makes to support the price after an offering, lawful under UK MAR’s safe harbour when announced in advance, limited to 30 days and the offer price, and reported to the FCA and the public.
Market sounding: UK MAR’s regime for the communication of information to investors before a transaction (a placing, a block) to gauge their interest: the scripts, the consent to receive inside information, the records and the cleansing when the transaction is announced or dropped.
Accelerated bookbuild: The overnight placing of a block of shares with institutions after the close, priced from the book at a discount, without a prospectus under the POATRs’ exemptions; the UK follow-on of choice, with the pre-emption guidelines capping non-pre-emptive issues at 20% since 2022 and a retail tranche often added through a platform.
Pre-emption guidelines: The Pre-Emption Group’s 2022 statement of principles: shareholders will support non-pre-emptive issues of up to 20% of the capital a year (10% unrestricted, 10% for an acquisition or a specified capital investment), with a retail offer encouraged; the frame of every UK placing.
POATRs: The Public Offers and Admissions to Trading Regulations 2024, in force from January 2026, which replaced the onshored Prospectus Regulation: a prospectus is required for an admission to a regulated market under the FCA’s rules, and a public offer of securities outside it is prohibited unless exempt (qualified investors, fewer than 150 persons, a £100,000 minimum, or an offer through an authorised public offer platform above £5 million).
UK Listing Rules: The FCA’s rules for a listing on the Official List, rewritten in July 2024 into a single equity shares (commercial companies) category with fewer shareholder votes and a disclosure-based regime; the London Stock Exchange’s admission rules sit beside them, with AIM for the growth companies.
DTR 5: The FCA’s Disclosure Guidance and Transparency Rules chapter on major shareholdings: a holder notifies the issuer and the FCA within two trading days at 3% of the voting rights and at every whole percentage above (5% for a fund manager), with derivatives aggregated; the counterpart of the US 13D and 13G.

SETS: The London Stock Exchange’s electronic order book for the FTSE All-Share and other liquid shares, with the opening and closing auctions and the market makers’ quotes beside it; the reference price for the RSP quotes and the dark MTFs.
RSP: The retail service provider network: the UK’s retail execution system, in which a retail broker’s order system requests quotes from several market makers (Winterflood, Peel Hunt, Stifel, the banks’ retail desks) and executes against the best within seconds, at or inside the order book price; the counterpart of the US wholesalers, without payment for order flow.
OTF: An organised trading facility, the discretionary venue for bonds and derivatives under UK MiFID, where the operator may use matched principal trading with the client’s consent.
Systematic internalizer: An investment firm dealing on own account against client orders on an organised, frequent and systematic basis, with firm quotes for liquid shares, the tick size regime on the quotes and the post-trade publication through an APA; the FCA removed the quantitative test in 2023 and kept the regime; the banks and the market makers run them.
Consolidated tape: The single record of trades across the UK venues and APAs: the FCA selected Etrading Software to run the bond tape (2025, live in 2026 as ETS Connect UK), with the equity tape to follow; the counterpart of the US tapes.
Tick size regime: The minimum price increments by liquidity band and price that UK MiFIR sets for the shares traded on the venues and quoted by the SIs; the FCA kept the regime after Brexit with its own calibration.
Gilt-edged market makers: The GEMMs: the banks and dealers the DMO recognises as primary dealers in gilts, with the obligation to bid at the auctions and to quote in the secondary market, and the privileges (the auction bids, the DMO’s facilities); the counterpart of the US primary dealers.
Gilts: The UK government bonds issued by the DMO: conventional (fixed coupon, semi-annual) and index-linked (to the RPI, moving to the CPIH), settled in CREST on T+1, traded by the GEMMs and on Tradeweb and Bloomberg, financed in gilt repo at LCH Ltd; the sterling benchmark curve.
Treasury bills: The DMO’s one, three and six-month bills, issued at the weekly tender and held by the money market funds and the banks as liquid assets, settled in CREST.

EMTN: A euro medium-term note program: the base prospectus and the standing documentation under which an issuer draws down bonds in the international market through its dealers; the format of most UK corporate and bank bond issuance.
Stamp duty reserve tax: The 0.5% tax on the purchase of UK shares, collected automatically through CREST on each settlement (stamp duty on paper transfers), with exemptions for AIM shares, ETFs and intermediaries (the market makers’ relief); the cost every UK retail equity order carries.
Dated Brent: The Platts assessment of the physical North Sea crude cargoes loading 10 days to a month ahead (Brent, Forties, Oseberg, Ekofisk, Troll, and WTI Midland since 2023), the price most of the world’s physical oil is sold against.
ICE Brent: The ICE Futures Europe Brent crude futures contract, cash settled against the ICE Brent index, the most traded oil futures with NYMEX WTI; the swaps and options on its monthly average hedge the Brent-linked production and consumption.
Banking base: The London term for the borrowing base of an RBL: the debt capacity computed from the banks’ economic model of the fields (production, costs, taxes, decommissioning) at their price deck.
Energy Profits Levy: The UK windfall tax on the ring fence profits of the North Sea oil and gas producers, introduced in May 2022 at 25%, raised to 38% from November 2024 on top of the 30% ring fence corporation tax and the 10% supplementary charge, ending on March 31, 2030 under the Finance Act 2025, with a revenue-based price mechanism announced to follow.

UK ETS Registry: The registry of the UK ETS, run by the Environment Agency: the operator holding accounts, the trading accounts, the transfers and the surrenders.
UK CBAM: The UK’s carbon border adjustment mechanism from January 1, 2027 on imported aluminium, cement, fertilisers, hydrogen, iron and steel, initially on the direct emissions.
Clean spark spread: The margin of a gas-fired power plant: the power price less the cost of the gas and of the allowances per megawatt hour; generators fix it by selling power and buying gas and allowances forward together.
Employee benefit trust: A trust (often in Jersey or Guernsey) set up by a UK company to acquire and hold shares for its employee share plans, funded by a loan or a gift from the company, consolidated in its accounts, its shares deducted from equity as own shares.

The bank quotes the client off the interbank market, deals, then hedges or warehouses the position. Two ways in: a voice or RFQ price built by a salesperson (V) or a streaming price from the pricing engine (E). Two ways out: each currency paid gross on its own rails (G) or payment versus payment in CLS (C). Access and settlement are independent choices; post-trade is shared.
Worked example, illustrative:client buys EUR 10,000,000 vs USD, spot, value T+2market 1.0850 / 1.0851V, voice client 1.0853; margin 2 pips, USD 2,000E, electronic client 1.08515; margin 1 pip, USD 1,0001 pip USD 1,000 on EUR 10mC, CLS net EUR 0, USD +2,000 to the bank

V: a human price, a few seconds firm, a wider margin, a hedge decided by the trader. E: a machine price, milliseconds firm, a thinner margin, flow internalized and the residual hedged by rules. G: the bank pays EUR in Frankfurt hours and waits for USD in New York hours, so it carries principal risk on the client for part of a day. C: both legs settle together or not at all, and only the net per currency moves.
Spot is value T+2 for most pairs; GBP/USD, USD/TRY, USD/RUB and USD/PHP are T+1. The dollar is on one side of about 88% of all FX turnover, so dealers price crosses through USD.
The electronic route is where most spot volume sits: single-dealer platforms, multi-dealer venues (FXall, 360T, FXGO, Bloomberg) and ECNs (EBS, Refinitiv Matching, Cboe FX, LMAX). The pricing engine skews its mid to attract flow that reduces inventory, and internalizes most client flow before hedging.
Last look is the dealer’s right to reject a client’s click within a short window after it arrives. The FX Global Code asks dealers to disclose how long the window is and what checks run in it.
Gross settlement leaves the bank exposed for the full principal of the leg it pays first. CLS removes that for its 18 currencies by settling both legs together across members’ accounts at CLS Bank, funded by net pay-ins at the central banks. A trade with a non-CLS currency, a non-CLS counterparty or an unmatched instruction falls back to gross settlement.
The bank is a CLS settlement member here: it holds the RTGS account or nostro agent in each currency and funds pay-ins in the early European morning. Smaller banks join as third parties through a member.
Spot is not a swap under UK EMIR, so there is no trade repository report; the bank still keeps a complete audit trail for best-execution and conduct reviews.
The spot lifecycle with three additions: a credit check before quoting, because a forward is a credit exposure until it settles; a trade repository report, because a forward is a derivative under UK EMIR; and a life of trade with daily mark to market until the value date.

The forward price is spot plus forward points, which are the interest differential between the two currencies for the period. The bank earns a wider margin than on spot because it carries the client’s credit for six months. The settlement rows are the spot rows moved to the value date; in between, the position is marked daily and, where a CSA exists, collateral moves.
Forward points = spot × (1 + USD rate × days/360) / (1 + EUR rate × days/360) − spot. With USD rates above EUR rates the EUR trades at a forward premium: the points are positive.
Credit: the bank’s exposure is the replacement cost if the client defaults, so a 6-month forward is priced against the client’s credit line and, for larger clients, charged CVA. Corporate hedgers usually trade on an uncollateralized line, funds on a CSA.
Regulation: FX forwards and swaps are swaps under UK EMIR but exempt from clearing and MTF trading (Treasury determination, 2012); reporting to a swap data repository, business conduct rules and recordkeeping still apply.
Settlement risk is the same as on spot, on the value date. Window forwards let a corporate draw the EUR over a range of dates; non-deliverable forwards settle the difference in USD (see NDF).
FX Window Forward, EUR 6,000,000 Drawn Over Months 1 to 3
A forward with a settlement window: the importer fixes one rate for EUR 6,000,000 and draws it in parts on any day between month 1 and month 3 as its supplier invoices fall due. The bank quotes the worst forward rate in the window, hedges to the window end and swaps each drawdown back to its date, keeping the forward points the client does not use. Each drawdown settles like a spot; the undrawn balance is delivered or closed on the last day.
Worked example, illustrative:client buys EUR 6,000,000 vs USD, any business day from day 30 to day 90outrights 1-month 1.0872, 3-month 1.0911 offerclient rate 1.0916 for every drawdown: the worst point plus 5 pipsdrawdowns EUR 2m on day 35, EUR 2.5m on day 60, EUR 1m on day 85balance EUR 500,000 delivered or closed out on day 90bank’s margin USD 3,000 plus the unused points, about USD 7,300 on the first drawdown (illustrative)

The window forward trades a slightly worse rate for not having to know the date. The bank prices the whole amount at the end of the window that is worst for the client and earns the forward points between each drawdown and that date. Operationally it is a parent deal with child deals: each drawdown is a spot-like settlement against the bank’s hedge, swapped back to its date.
United Kingdom: the time option forward is a standard product of the UK banks for importers and exporters; a forward entered to pay for identifiable goods and services is a means of payment outside the MiFID financial instruments (Article 10 of the MiFID Delegated Regulation, kept in UK law), so it is neither a MiFID investment nor reported under UK EMIR; a window forward that is not a means of payment is a derivative reported under UK EMIR, by the bank on behalf of an NFC- client.
Pricing: the bank quotes the forward rate across the window that is worst from the client’s side: the window end when the client buys a currency at a forward premium, the window start when it buys at a discount. The difference from a dated forward is the price of the flexibility; the bank earns it when the client draws before the worst date.
Regulation: a physically settled FX forward is a swap under UK EMIR but was excluded from clearing, MTF trading and the uncleared margin rules by the Treasury determination of November 2012; the trade is reported to the trade repository by the bank and the FCA’s business conduct rules apply. A corporate trades on the bank’s credit line, without a CSA.
Operations: the drawdown needs notice (two business days, one for GBP/USD), a minimum amount and the payment instruction; the system splits the parent deal into a child deal per drawdown and keeps the undrawn balance; the client’s treasury management system mirrors the same balance.
Variants: a fully open window from the trade date (at a wider rate), the time option forward of the UK and Canadian banks (the same product under another name), the participating forward and the flexible forward. Under ASC 815 a window forward can be designated as a cash flow hedge of the forecast purchases when the documentation names the window and the amounts.
An FX swap is one trade with two exchanges: the client sells EUR spot and buys it back in three months, to borrow USD against EUR without taking a currency view. The price is the forward points, so the risk is an interest-rate differential, not spot. FX swaps are the largest instrument in the FX market and the main short-term funding tool of banks and asset managers.
Worked example, illustrative:client sells EUR 10,000,000 spot, buys back in 3 monthsspot reference 1.08505 mid3m points market +58 / +60client points +62far rate 1.09125margin 2 pips, USD 2,000cost to client USD 62,000 for 3 months, about 2.27% annualized over the EUR rate

The near leg settles like a spot on T+2 and the far leg like a forward three months later, each with its own payments. The spot reference is agreed at mid, so the only price the client negotiates is the points. The swaps desk hedges the differential with the market or in the bank’s own funding book.
An FX swap is an exchange of two currencies now with a reversal at a forward rate; economically a collateralized loan in one currency against the other. The BIS 2022 survey puts swaps at about 51% of daily FX turnover.
The dealer’s risk is the forward points, driven by the two money-market curves and by cross-currency basis (the premium for USD funding through FX swaps over cash markets, which widens at quarter and year ends).
Settlement risk arises twice, on each leg. Both legs are CLS-eligible. Forward exposure on the far leg is a credit exposure and is reported to the trade repository like a forward.
Variants: tom-next and spot-next rolls to carry a spot position overnight; cross-currency basis swaps for longer dates exchange principal and floating interest (see Rates, Cross-Currency Swap).
For currencies that cannot be delivered offshore (BRL, CNY, INR, KRW, TWD and others) the forward is cash settled: at the fixing date the official rate is compared with the contract rate and the difference is paid in USD. The lifecycle gains a fixing event, and settlement is a single USD payment.
Worked example, illustrative:client sells BRL 50,000,000 vs USD, 3-month NDF, cash settled in USDspot 5.1500market outright 5.2220 / 5.2240client 5.2260margin 20 points, about USD 3,700PTAX fixing 5.3000settlement USD 133,585 to the client

Pricing follows the forward. The difference comes at the end: two business days before value the official fixing is published, the bank computes the difference between the contract rate and the fixing on the notional, and only that difference moves, in USD. The client never touches BRL; a real-money hedger offsets the loss on its Brazilian assets with the gain on the NDF.
NDF points embed the offshore interest differential and a convertibility premium; for BRL the onshore DI curve and the offshore NDF curve can differ by tens of basis points.
EMTA publishes the template terms per currency: fixing source (PTAX for BRL, published by the central bank), fixing time, valuation and settlement dates, and fallbacks for an unscheduled holiday or a price-source disruption.
NDFs are swaps without the forward exemption: trade repository reporting, uncleared-margin rules, and no MTF trading mandate, since no NDF has been made available to trade. Clearing at LCH ForexClear is voluntary and growing.
Settlement risk is reduced to the net difference, which makes NDFs the standard hedging tool for emerging-market exposure held by US funds.
The client buys the right, not the obligation, to buy EUR at 1.1000 in three months and pays a premium up front. The bank hedges the delta in spot and the vega in the interdealer options market, then re-hedges daily. The lifecycle has three dated events: premium settlement, expiry and, if exercised, delivery.

An option splits the trade into three dated events. The premium settles like a spot payment on T+2. At expiry the client exercises only if spot is above the strike; the option turns into a spot trade at 1.1000, settled two days later like any spot. Between the two, the desk re-hedges its delta every day: the option book’s P&L is the premium earned less the cost of those re-hedges.
FX options are quoted in implied volatility; the premium follows from Garman-Kohlhagen on the forward. The surface is built from at-the-money vol, 25-delta risk reversals (skew) and butterflies (smile).
Cuts: New York 10:00 is the standard expiry for USD pairs, Tokyo 15:00 for yen crosses. Delivery is spot settlement from expiry. Cash settlement at the fixing is common for funds that do not want delivery.
The buyer’s credit risk is on the bank for the life of the option; the bank’s on the client ends when the premium is paid. A sold option (client writes) reverses that and sits on the client’s line with margin.
Barriers, digitals, target redemption forwards and accumulators are built from vanillas and sold as hedging structures; they add continuous monitoring events (barrier touched or not) to the lifecycle.
Average Rate Forward and Option, a Month of EUR Receipts
An exporter that converts customer receipts every day hedges the month’s average rather than one date: the average rate forward (F) locks the average against a fixed rate, the average rate put (O) floors it for a premium below a vanilla’s. The bank hedges a strip of forwards that falls away fixing by fixing; at the end only the difference between the average of the fixings and the strike is paid, in USD, while the client sells its receipts at spot as usual.
Worked example, illustrative:client sells EUR 5,000,000 of monthly receipts, averaged over 21 fixingsF, average forward 1.0856 against the average; pays USD 33,000 to the clientO, average put strike 1.0800, premium 0.21%, USD 11,550; pays USD 5,000vanilla comparison 1-month put at 0.45% for the same strikeaverage of the fixings 1.0790 (illustrative)fixing WM/Refinitiv 4pm London, 21 business days

The average of 21 fixings moves less than the rate on any one day, so the option on it is cheaper and the forward on it matches a flow converted daily. The bank’s hedge is a strip that shortens with each fixing; the settlement is a single cash payment, which makes the instrument a swap that is reported, marked daily and sold under the business conduct rules.
United Kingdom: a cash-settled average rate forward or option is a financial instrument with no means of payment exclusion, sold under COBS to a categorized client with the product governance rules, and reported under UK EMIR (by the bank for an NFC- client); the WM/Refinitiv 4pm London fix is the usual fixing.
Averaging: the arithmetic average of the fixings over the period (daily, weekly or monthly fixings; the WM/Refinitiv 4pm London rate, the ECB reference rate for EUR, the central bank’s rate for some currencies), sometimes weighted by the expected flows; a disrupted fixing falls back to the next source in the confirmation.
Pricing: the variance of a full-period arithmetic average is about a third of the variance of the rate at the period end, so an average rate option costs roughly half to two thirds of a vanilla at the same strike; an average rate forward prices at the average of the forwards over the fixing dates.
Regulation: cash settlement takes the average rate forward out of the Treasury determination for physically settled forwards: it is a swap, reported to the trade repository, sold with the pre-trade mid-market mark and the daily mark, and outside the clearing mandate; a commercial end user posts no margin under the prudential rules.
Hedge accounting: under ASC 815 an average rate instrument can hedge a group of forecast transactions in the same period when their timing matches the averaging dates; the client documents the hedge at inception and assesses its effectiveness each quarter on the bank’s marks.
A collar is a corporate hedge built from two options: the client buys protection below 1.0700 and pays for it by giving up the upside above 1.1300. No premium changes hands; the bank’s margin is in the strikes. The lifecycle is the option lifecycle with two legs and a suitability step up front.
Worked example, illustrative:client sells EUR 10,000,000 in 6 monthsforward 1.0970bought put strike 1.0700sold call strike 1.1300 (fair 1.1330)premium zeromargin about USD 30,000 in the strike shiftexpiry spot 1.0600, put exercised

The structurer solves the call strike so that the premium of the sold call pays for the bought put, then shifts it a little in the bank’s favor. At expiry one of three things happens: spot below the put strike, the client exercises; spot between the strikes, both expire and the client sells at market; spot above the call strike, the bank exercises its call and the client sells at 1.1300. Hedging and settlement are those of the vanilla option, twice.
Collars, participating forwards, target redemption forwards and accumulators are the main corporate FX structures. Each trades off premium against path risk or capped upside; the margin is in the strikes or in the leverage.
Suitability: the sold leg can lose the client money, so the bank documents the client’s classification, provides a term sheet and scenario analysis, and keeps records of the recommendation.
Hedge accounting (ASC 815): a zero-cost collar on a forecast sale can qualify as a cash-flow hedge if the strikes and dates match the exposure; the client tests effectiveness quarterly using the bank’s marks.
Each option is reported to the trade repository; the bank’s risk is the net Greeks of the two legs, re-hedged daily like a vanilla.
FX futures are the listed, cleared alternative to the forward: the same forward price in a standard contract on CME, margined daily at the clearing house, and physically delivered through CLS if held to expiry. The bank acts as broker and clearer, not as counterparty, and its FX desk trades the basis between the future and the OTC forward.
Worked example, illustrative:client buys 500 December 6E, EUR 62,500,000price 1.0895 (spot plus points to the third Wednesday)IM about USD 2,500 per contract, USD 1.25m1 pip USD 12.50 per contract, USD 6,250 on the positionroll December to March spreaddelivery EUR vs USD through CLS on the third Wednesday

The clearing broker lifecycle of any listed future, with an FX ending: the position is marked and margined twice a day at CME; most holders roll before the last trading day; positions that go to delivery exchange the currencies through CLS between the clearing members, so only CLS-eligible currencies trade as deliverable futures.
CME lists futures on the major pairs (6E, 6J, 6B, 6C, 6A) and cross rates, with quarterly expiries; volume is a fraction of the OTC market but it is where funds, CTAs and corporates that cannot sign an ISDA get FX exposure, and the clearing house removes the bilateral credit question.
Pricing: a future is a forward with daily settlement, so it trades at spot plus the forward points to delivery; the small difference (the futures-forward basis) comes from margin financing and convexity and is arbitraged by bank FX desks through EFPs.
Delivery: the contracts are physically delivered through CLS on the third Wednesday, so the deliverable pairs are CLS currencies; non-deliverable currencies (BRL, CNH) trade as cash-settled futures like NDFs.
The clearing broker operating model (segregated customer margin, daily settlement, large-trader reporting, position limits) is described under Inside the Bank, Futures; the bank earns execution and clearing fees, not a spread.
FX›FX Prime Brokerage
FX Prime Brokerage, Give-Ups From Executing Dealers
A prime brokerage arrangement lets a fund trade with many dealers on one credit line. Every trade the fund does with an executing dealer is given up to the bank, which becomes the counterparty to both sides at the same rate: one trade with the dealer, one with the fund. The bank carries no market risk, only the fund’s credit, which it covers with margin on the net open position. Settlement is netted: CLS with the dealers, net wires with the fund.
Worked example, illustrative:fund buys EUR 50,000,000 vs USD at 1.0860 from dealer Dgive-up matched and accepted in secondsPB fee USD 7 per million, USD 380 on this ticketlimits USD 2bn gross, 12 executing dealersIM 2% of net open position, USD 6.2mday net EUR +12m / USD −13.03m, T+2

The arrangement rests on a prime brokerage agreement with the fund and designation notices with each dealer. Once in place, the fund trades with any designated dealer in the bank’s name, the give-up hub matches each ticket against the limits, and the bank books two offsetting trades. At the end of the day the bank nets the fund’s position, calls margin, settles with the dealers in CLS and with the fund net per currency.
FX prime brokerage is how hedge funds, CTAs and smaller banks reach the interbank market: one ISDA and one margin relationship with the prime broker, access to every dealer and ECN that has signed a designation notice, and netting of all their trades in one place.
The give-up hub (Traiana Harmony, owned by CME Group) carries the designation limits and matches the dealer’s and the fund’s notices; acceptance is automatic within limits. Before the hub, give-ups were faxed and phoned, and a 2015 CHF event showed what unmatched give-ups cost.
The prime broker’s economics: a per-million fee (USD 2 to 10 depending on volume), the spread on margin cash, and cross-selling of forwards, options and financing; its risk is the fund’s credit, managed through net open position limits, initial margin, intraday monitoring and the right to stop accepting give-ups.
Forwards and options given up are swaps for the bank: it reports them to the trade repository as the fund’s counterparty, and the uncleared-margin rules apply between the bank and the fund. Spot give-ups are not reportable.
UK Treasury bills are the risk-free end of the sterling money market: discount instruments of 1 to 12 months issued weekly by the DMO, about GBP 70 billion outstanding, a core holding of the sterling money market funds and the bank’s own liquidity buffer. Quoted in yield, settled DVP in CREST, redeemed at par. The bank bids at the tender for itself and clients (P) and makes a secondary market (S).
Worked example, illustrative:client buys GBP 500,000,000 3-month billsP auction highest accepted 3.950%, price 99.0248P client 3.945%, margin GBP 6,000S screen 3.960 / 3.950S client 3.945%, price 99.1746 for 77 dayssettlement CREST DVP, T+0 or T+1maturity par, GBP 500m

P: the DMO announces the tender, bids go in on Friday at 11:00 through its tender system, the bank passes its award to the client at its yield less a fraction. S: the bill desk quotes through the interdealer screen and covers there or from its inventory. Settlement is DVP in CREST; at maturity the DMO pays par and the cash rolls into the next tender.
United Kingdom: the DMO sells bills at the weekly Friday tender to the Treasury bill primary participants; bills settle at CREST on T+1; the Bank of England’s floor system, with Bank Rate paid on all reserves and the short-term repo facility, sets the floor for the rates.
Bills are quoted in yield on an actual/365 basis: price = 100 / (1 + yield × days/365). One basis point on GBP 500 million for 91 days is about GBP 12,500.
The DMO tenders bills every Friday (1, 3 and 6 months, with 12-month bills from time to time) and issues ad hoc bills for its cash management; the tender is competitive only, on a bid-yield basis, through the UK Treasury bill primary participants. The sterling money funds, the banks’ liquidity buffers and the local authorities are the marginal buyers.
Bills are level 1 HQLA, eligible at the Bank of England and at LCH Ltd, and the collateral of choice in repo; the bank’s bill desk sits between the client franchise and treasury’s liquidity management.
Settlement is T+1 or same day; CREST DVP works for both. Redemption at par is paid by the DMO through CREST to the holder of record.
Unsecured short-term notes (1 to 270 days) issued by corporates and financials, and asset-backed CP issued by bank-sponsored conduits. The bank is the dealer: each morning it places the issuer’s paper with money market funds and corporate treasuries, settling the same day through CREST’s money market instruments program. Most paper is held to maturity and rolled.
Worked example, illustrative:issuer GBP 300,000,000 30-day A-1/P-1rate 5.28% discount, OIS + 2 bpdealer fee 5 bp annualized, about GBP 12,500client fund buys GBP 150m, price 99.5600settlement same day at CREST, MMImaturity day 30, par; issuer rolls

The issuer tells the dealer how much and for how long; the dealer posts levels to investors and fills the order by mid-morning, acting as principal for a few minutes. The issuing and paying agent creates the notes at CREST and they settle delivery versus payment the same day, proceeds to the issuer by close. Thirty days later the issuer funds the IPA, normally with new paper, and CREST pays the holders.
United Kingdom: the bank’s dealer places sterling commercial paper and certificates of deposit at CREST and euro commercial paper at the ICSDs, same day or T+1; asset-backed commercial paper from the bank conduits runs under the UK securitisation rules; the issuers are the banks, the corporates and the public bodies.
The US CP market is about GBP 1.3 trillion: financial CP (banks, including Yankee CP from foreign banks), nonfinancial CP (industrials) and ABCP (conduits funding trade receivables, auto loans and credit cards with full liquidity support from the sponsor bank).
CP is exempt from the prospectus requirement as money market instruments under the POATRs; 4(a)(2) private placement CP has no maturity limit. Ratings (A-1/P-1, A-2/P-2) decide which funds can buy; 2a-7 money fund rules limit second-tier paper.
Settlement runs through the ICSDs’ same-day settlement: issuing and paying agents create and redeem book-entry notes; same-day DVP with intraday risk controls after the 2008 reforms (the IPA can refuse to pay maturities until it is funded, and CREST has a largest-provisional-net-credit limit).
The dealer earns a fee of a few basis points and takes little balance-sheet risk; the issuer’s risk is pension transfer, covered by committed backup lines from banks, which rating the agencies and supranationals require for A-1/P-1.
Wholesale Deposits and Certificates of Deposit, the Bank as Issuer
Wholesale deposits are the bank’s own funding sold as a product: corporate treasuries, money funds and other banks place cash with the bank for a term, as a time deposit (a book entry) or a negotiable certificate of deposit (a CREST-eligible instrument the holder can sell). The desk prices off treasury’s funding curve, the deposit lands in the deposit system, not the trading book, and the lifecycle ends with principal and interest at maturity.
Worked example, illustrative:client places GBP 100,000,000 for 6 monthsfunding target OIS + 15 bpclient rate 5.35%, actual/360, interest at maturityform certificate of deposit at CREST, or time depositmaturity day 182: GBP 102,704,722regulatory stable funding until 30 days before maturity

The client asks for a rate; treasury decides what six-month money is worth to the bank; the desk quotes a CD or time deposit. The cash arrives by CHAPS and becomes a liability. A certificate of deposit lives at CREST and can change hands in the secondary market; a time deposit stays on the books. At maturity the paying agent returns principal and interest.
United Kingdom: the bank issues certificates of deposit and takes wholesale deposits under the PRA’s liquidity rules (the LCR and the NSFR) and the FSCS’s coverage of £120,000 for eligible deposits; the bail-in rules of the Banking Act apply to the senior debt and the ring-fencing rules separate the retail bank from the markets business; the Bank of England has no minimum reserve requirement, only the cash ratio deposits.
Negotiable CDs (GBP 100,000 minimum, usually GBP 1 million+) are issued by banks and US branches of foreign banks (Yankee CDs), held mainly by prime money funds; they settle at CREST as money market instruments. Time deposits and Eurodollar deposits (offshore) are bilateral book entries confirmed by MT320.
Pricing is treasury’s funds transfer price: the bank’s marginal cost of term funding (OIS plus its credit spread) less the regulatory value of the deposit. Operational deposits and retail deposits are worth more than wholesale term money under the LCR.
Regulation: deposits are covered by the FSCS to £120,000 (irrelevant at this size), subject to the PRA’s liquidity rules, and classified under the LCR by counterparty and maturity; brokered deposits have their own rules.
The same desk takes interbank deposits, issues the bank’s own CP and runs the FX swap book: all are treasury’s short-term funding sources, managed against the liquidity buffer of bills and reserves.
The overnight unsecured market is how a bank balances its reserves account at the end of the day: borrowing overnight, unsecured, from another bank or a non-bank lender, settled through CHAPS into its reserves account at the Bank of England and repaid the next morning. The rate is SONIA, the Bank of England’s benchmark, a few basis points below Bank Rate. The lifecycle is one day long and repeats every day.
Worked example, illustrative:bank borrows GBP 2,000,000,000 overnight, unsecuredrate 3.95% SONIA; Bank Rate 4.00%; the Discount Window aboveinterest GBP 216,438 for one daylender a money market fund through a brokersettlement CHAPS by 18:00 London timerepayment next morning, GBP 2,000,216,438

gilt projects the day’s reserve position; if short, the desk borrows in the brokered the overnight rate market, mostly from Federal Home Loan Banks that have cash and no access to interest on reserves. The lender wires reserves to the bank’s Bank of England account before the close; the bank reports the trade to the Bank of England; next morning it repays with interest. Repo and the Bank of England’s facilities are the alternatives.
United Kingdom: the overnight unsecured market runs on CHAPS with Bank Rate paid on reserves as the floor and the Discount Window Facility above; SONIA is the benchmark from the banks’ wholesale deposits; the reserves created by the asset purchases keep the market modest, and the short-term repo facility is where the banks top up as the reserves run down.
The overnight unsecured market is modest (SONIA is computed from about GBP 50 billion a day of the banks’ borrowings from banks and non-banks) because quantitative easing left the banks with ample reserves, now shrinking under quantitative tightening; SONIA replaced sterling LIBOR as the benchmark at the end of 2021 and is the reference for the swap market, with gilt repo rates close to it.
The Bank of England pays Bank Rate on all reserves (a floor system, with the short-term repo facility supplying reserves at Bank Rate as the balance sheet shrinks and the Discount Window Facility above it); SONIA trades a few basis points below Bank Rate because the non-bank lenders in the market cannot hold reserves.
Daylight: CHAPS runs from 06:00 to 18:00 London time; most overnight trades settle in the late afternoon; the Bank of England provides intraday liquidity against collateral at no charge.
Unsecured interbank lending is a credit exposure for the lender; after 2008 banks shifted to secured funding (repo), and regulation (LCR, NSFR) penalizes reliance on overnight wholesale funding, so this trade is for balancing, not for funding the balance sheet.
Repurchase Agreements, Bilateral, Triparty and Cleared at LCH Ltd
Repo is a market of some GBP 1.5 trillion outstanding in the UK, mostly gilt repo that finances dealer inventories and invests money fund cash: a sale of securities with an agreed repurchase tomorrow, economically a secured loan. Three settlement models: bilateral DVP in CREST for specific collateral (B); triparty, where Euroclear Bank or BNY allocates general collateral from the bank’s box (T); and sponsored, where the bank brings its client into LCH Ltd clearing and nets the trade (S).
Worked example, illustrative:fund lends GBP 1,000,000,000 overnight against giltsGC rate 5.31% (SONIA); fund gets 5.32%margin 102%: GBP 1.02bn collateralinterest GBP 147,778 for one dayB special hedge fund borrows a 10-year at 5.08%, 2 bp to the bankS LCH Ltd novates; the bank netsrepurchase next morning, GBP 1,000,147,778

The desk finances its gilt inventory and runs a matched book. A money fund’s cash comes in overnight at a basis point over the Bank of England’s facility; a hedge fund borrows a specific bond in reverse repo at a special rate. B settles bond for cash on CHAPS; T lets the triparty agent pick and hold the collateral; S puts LCH Ltd in the middle so the bank’s balance sheet nets. Next morning the cash comes back with interest and the collateral goes home, and most of it rolls.
United Kingdom: gilt repo clears at LCH Ltd RepoClear (the £GC and term £GC baskets for the cleared triparty basket), priced off SONIA; Euroclear Bank, BNY and J.P. Morgan run the triparty; every repo is reported under UK SFTR and in the Bank of England’s Sterling Money Market Data; the Bank’s short-term and indexed long-term repo operations are the other side of the market.
Rates: SONIA is the Bank of England’s overnight unsecured benchmark from the banks’ wholesale deposits; the repo market trades off it, with the £GC rate for cleared general collateral and specials below GC when a gilt is in demand; the spread is the lending fee the owner of the bond earns.
Triparty: Euroclear Bank, BNY and J.P. Morgan are the triparty agents for sterling and international collateral, with LCH’s £GC and term £GC as the cleared general collateral products; they value, allocate and substitute collateral and hold it in the lender’s account; the Bank of England’s own operations settle through them.
LCH Ltd sponsored service: a netting member sponsors clients (money funds, hedge funds) into LCH Ltd; LCH Ltd clears repo between its members and, through sponsored clearing at LCH Ltd, the funds, without a mandate. Netting cuts the dealer’s balance sheet and leverage-ratio exposure.
Documentation and risk: the ICMA GMRA; haircuts of 2% on gilts to 10%+ on corporates and equities; daily mark to market and margin; the lender’s risk is the collateral falling in value after a default (hence haircuts), the borrower’s is the lender failing to return it.
Money Markets›Securities Lending
Stock Borrow From an Agent Lender
Borrowing shares to settle short sales and hedges, against cash collateral at 102%. The lender is a pension or fund acting through its custodian as agent lender; the bank borrows, lends on to its prime brokerage clients and keeps the spread. The lifecycle is open ended: daily marks, a monthly rebate on the cash, manufactured dividends, and a return whenever either side calls.
Worked example, illustrative:bank borrows 1,000,000 shares, GBP 50m, hard to borrowcollateral cash 102%, GBP 51mrebate 1.00% vs the overnight rate 5.33%: fee 433 bpon-lend to client 5.00%: 67 bp spreadmark daily to 102%dividend manufactured payment to the lenderrecall 3 business days’ notice

The desk locates the shares with an agent lender, agrees a rebate rate that embeds the borrow fee, and takes delivery against cash at CREST; it passes the shares to the client’s short and charges a higher fee. Every day the collateral is marked; every month the rebate is paid; on dividend dates the borrower manufactures the dividend. When the lender recalls or the short is covered, the shares go back against the cash.
United Kingdom: the bank borrows from the agent lenders (the custodian banks, the insurers’ and the pension schemes’ lending programs), against securities or cash collateral at 102 to 105%; the UK short selling rules require the locate, UK SFTR the loan-by-loan report; the collateral moves through CREST and the triparty agents.
The US securities lending market has about GBP 3 trillion on loan; most supply comes from pensions, mutual funds and ETFs through agent lenders (State Street, BNP Paribas Securities Services, JPMorgan, Northern Trust) and most demand from prime brokers covering hedge fund shorts.
Cash collateral is the US norm (non-cash collateral, gilts and equities, is the norm in Europe); the lender reinvests the cash and pays a rebate; a low or negative rebate is a high borrow fee. Fees on general collateral names are 10 to 20 bp; on hard-to-borrow names hundreds or thousands of bp.
Regulation: UK SFTR requires both counterparties to report each loan to a trade repository by the next working day; the UK short selling rules requires a locate arrangement before a short sale; the CASS rules governs how an investment firm can use customer securities (rehypothecation limits); Basel capital rules price the balance-sheet use.
The same desk runs equity repo, lends the bank’s own inventory and clients’ fully-paid shares (fully-paid lending programs), and manages the collateral through triparty agents; corporate-action and voting management (recalls before record dates) is the operational core.
The interest rate swap is the benchmark OTC derivative. Under UK EMIR and the UK derivatives trading obligation a standard SONIA swap between a dealer and a financial client must be executed on a trading venue and cleared at a CCP, so the bank’s counterparty after a few seconds is LCH SwapClear, not the client. The lifecycle is dominated by the CCP: initial margin, daily variation margin, netted coupons, compression, and fungible unwinds.
Worked example, illustrative:client receives fixed GBP 100,000,000, 10 years, vs SONIA compoundedmarket 3.850 / 3.855client 3.848%DV01 about GBP 83,000margin 0.2 bp, about GBP 16,600IM 1% to 3% of notional, portfolio nettedVM daily cash by 09:00 London time

The client asks three dealers on the trading venue; the bank wins; within seconds the trading venue submits the trade to the CCP, which accepts it and becomes the counterparty to both. The bank hedges its rate risk with gilt futures or an interdealer swap. For ten years the CCP calls margin daily and nets every coupon with the rest of the bank’s book; the client can unwind with any dealer, because the trade is against the CCP.
Market structure since UK EMIR and the UK MiFIR trading obligation: the standard SONIA swaps must be executed on a trading venue (RFQ or the order book) and cleared; the venue runs a pre-trade credit check against the client’s clearing broker limit so clearing is certain before the trade is done.
Clearing house: LCH SwapClear clears almost all cleared sterling swaps; the bank is a direct clearing member, the client a customer of a clearing broker. Margin: initial margin covers a 5-day close-out at 99%+; variation margin is the daily mark.
SONIA replaced sterling LIBOR at the end of 2021; term SONIA exists for loans and a few products under the UK Benchmarks Regulation. Floating legs pay SONIA compounded in arrears over the period, with a 2-day payment delay; the Bank of England publishes SONIA each morning at 09:00 London time.
Fungibility: because both sides face the CCP, a client can close a position with a different dealer and the CCP nets the two trades. Compression services tear up offsetting trades across members to cut gross notional.
Uncleared alternatives (swaptions, non-standard swaps) stay bilateral under the ISDA with daily VM and, above thresholds, IM segregated at a custodian (see Swaption).
An option on a swap, and the main rates derivative that stays bilateral: swaptions are not clearable, so the trade lives under the ISDA and CSA for its whole life, with daily variation margin and, for large counterparties, initial margin segregated at a custodian. The lifecycle adds the premium, the expiry and a settlement that can be cash or a new cleared swap.
Worked example, illustrative:client buys 1y10y payer swaption, GBP 100,000,000, strike 3.90%market vol 95 / 98 normal bpclient premium 3.10%, GBP 3,100,425margin 1.5 bp, about GBP 47,500delta 50%: pay on GBP 50m forward swapexpiry 10y at 4.40%, exercisedsettlement about GBP 4,020,000 cash

The desk prices the option on its vol cube, hedges its delta with a forward-starting swap (cleared) and its vega in the broker market. Because the trade is bilateral, collateral moves between the bank and the client every day for a year. At expiry the client exercises; the standard since 2021 is cash settlement at the collateralized cash price, or physical settlement into a cleared swap.
Swaptions are quoted in normal (basis-point) volatility since rates went near zero; the cube is expiry × tenor × strike. Caps and floors are strips of options on single SONIA periods and follow the same lifecycle with many expiries.
Uncleared-margin rules (FCA and prudential regulators): daily VM for all financial counterparties since 2017; IM, calculated with ISDA SIMM, for entities above GBP 8 billion average aggregate notional, posted to a segregated third-party custodian.
Settlement: the ISDA 2021 definitions made collateralized cash price the standard cash settlement method for GBP swaptions, replacing the old par yield curve unadjusted method; physical settlement delivers a swap that is then cleared.
The bank as writer has no credit exposure after the premium is paid; the client has exposure to the bank and receives VM. The desk’s risk is vega, gamma and the delta re-hedging cost.
SONIA futures are exchange-traded short-term interest rate futures, the liquid proxy for the money-market curve. The bank is not the counterparty: it executes the client’s order on ICE Futures Europe and clears it as a clearing member, holding the client’s margin in segregation. The lifecycle is the exchange’s: anonymous matching, novation to ICE Clear Europe, twice-daily cash variation margin, and cash settlement to compounded SONIA.

The order goes through the clearing broker’s risk filter to the exchange’s order book and fills against the market; ICE Clear Europe becomes the counterparty to both sides. The clearing broker collects initial margin into segregated customer funds and passes variation margin between the client and the CCP every day. At expiry the contract cash settles to compounded SONIA; most clients roll before that.
United Kingdom: the three-month SONIA futures trade on ICE Futures Europe and clear at ICE Clear Europe (CME lists a SONIA contract too); they are exchange-traded derivatives outside the UK EMIR clearing obligation, which covers the SONIA swaps; the contracts replaced the short sterling futures when LIBOR ended in 2021.
Three-month SONIA futures (SR3) replaced Eurodollars in 2023; one-month SONIA (SR1) covers the near dates. Prices are 100 minus the rate; a 0.005 tick is GBP 12.50 on SR3.
The clearing broker model: the bank registers with the FCA, is a member of the FCA, holds customer margin in segregated accounts (FCA rules 1.20 and 1.25), computes segregation daily and faces the clearing house for all customer positions as principal, with the customers’ margin behind it.
ICE Clear Europe marks positions twice daily; variation margin is a cash settlement, not collateral, so futures have no counterparty credit exposure beyond one day’s move and the IM covers that.
Clients use SONIA futures to hedge or express views on Bank of England policy; dealers use them to hedge swap books and FRAs. The strip of consecutive contracts gives the market-implied path of the policy rate.
gilt futures are the exchange-traded way to take or hedge duration. The clearing broker lifecycle is that of SONIA futures, with a different ending: gilt futures are physically deliverable, so a short held into the delivery month delivers the cheapest-to-deliver note on CREST against an invoice price. Most positions are rolled before that.

The client’s sell order fills on CBOT; ICE Clear Europe novates it; the clearing broker holds the margin. Daily variation margin tracks the move in the cheapest-to-deliver note. Before first notice day the client rolls to the next contract; a short that stays delivers a real gilts against the invoice price, and that delivery is what anchors the futures price to the cash market.
United Kingdom: the long gilt futures (with the medium and short gilt contracts) trade on ICE Futures Europe and clear at ICE Clear Europe; delivery is of a deliverable gilt through CREST; the conversion factors and the cheapest to deliver work as in the US.
CBOT gilt futures: 2-year (TU), 5-year (FV), 10-year (TY), Ultra 10-year (TN), Bond (US), Ultra Bond (UB). The deliverable basket for TY is notes with 6.5 to 10 years remaining; the conversion factor prices each at a 6% yield.
The cash-futures basis trade (long the CTD note financed in repo, short the future) is a large hedge-fund strategy and a focus of regulators since 2023; the bank’s Treasury desk runs the same trade to hedge inventory.
Exchange-for-physical (EFP) and block trades let the bank cross a futures leg against cash bonds or large sizes off the order book, reported to ICE Futures Europe within 5 to 15 minutes.
Delivery is rare (under 2% of open interest) but it is the mechanism that keeps the future priced off the deliverable notes; the short holds the delivery option (which note, which day in the month).
Options on Gilt Futures, the Bank as Clearing Member and Market Maker
Options on futures are listed options whose underlying is a futures contract, cleared at ICE Futures Europe: premium paid in full the next day, no margin for the buyer, SPAN margin for the writer, and exercise into a futures position instead of a cash settlement. The bank clears the client’s option as clearing broker and, on its options desk, makes markets in the same strikes and hedges in the futures.

An order, a fill on ICE Futures Europe, clearing, the premium the next day, then no cash flows until expiry unless the client sells the option back; at expiry the in-the-money put turns into a short futures position and the futures lifecycle takes over. The writer on the other side runs the delta hedge and posts margin every day.
United Kingdom: options on the long gilt futures trade on ICE Futures Europe and clear at ICE Clear Europe; the bank’s market making is under ICE Futures Europe’s liquidity provider schemes and the FCA’s market making rules.
Options on futures exist for every major contract: gilts and bonds, SONIA, FTSE 100 futures, crude oil, natural gas, gold, corn; they are the listed volatility market for rates and commodities, with weekly expiries now alongside the monthlies and quarterlies.
Premium-paid versus futures-style: US options on futures are paid in full upfront (equity style), so the buyer has no margin and the seller is margined; some exchanges (and the LME) margin both sides daily instead (futures style).
Exercise: American style, into a futures position at the strike; the clearing house assigns writers at random through their clearing members; automatic exercise applies to in-the-money options at expiry unless instructed otherwise.
The bank’s roles: clearing broker for the client, market maker on the exchange, and user of the same options to hedge its swaptions and caps (the rates vol surface is built from both listed and OTC prices).
A cap is a strip of options on the floating rate: each quarter, if compounded SONIA ends above the strike, the cap pays the difference. The bank sells it, hedges the delta in futures and swaps and the vega in the options market, and settles a caplet every quarter the rate is above the strike. A floor is the mirror image, bought by lenders and floating-rate investors; a collar is one of each.
Worked example, illustrative:client buys 3-year SONIA cap, strike 5.00%, GBP 100,000,000market 1.25% / 1.35%client premium 1.38%, GBP 1,380,000margin 3 bp, about GBP 30,000caplets 12 quarterly, compounded SONIA in arrearsperiod 5 SONIA 5.40%: pays GBP 104,444

The premium is paid once; then twelve quarterly observations decide twelve payments, most of them zero. The desk re-hedges delta daily for three years and posts variation margin to the buyer on the cap’s value. The borrower’s loan interest and the caplet payments move together, which is the purpose of the hedge.
Pricing: each caplet is a call on the forward rate, priced with the normal (Bachelier) model since rates went near zero; the cap and floor vol surface is quoted by strike and expiry, and cap-floor parity ties a cap minus a floor at the same strike to a swap.
Users: commercial real-estate borrowers (lenders require a cap on floating-rate loans), leveraged borrowers and CLOs, floating-rate note issuers; insurers and banks buy floors on their floating assets; corporates buy collars to cap cost while giving up the benefit of falling rates.
SONIA conventions: the caplet observes SONIA compounded in arrears over the period with a payment delay of two business days (the ISDA 2021 definitions); the SONIA-era caplet fixed at the start of the period and paid at the end.
Caps are not clearable (no CCP offers them), so they live under the ISDA and CSA with daily VM; the bank, having sold the option, is the one posting collateral as rates rise.
A forward rate agreement is the simplest rate lock: one period, one fixed rate against the floating rate of that period, settled in cash. In the SONIA era it fixed at the start and settled discounted; the SONIA version is a single-period swap settled when the period ends. The futures strip is both the price source and the hedge. FRAs have largely given way to SONIA futures and short swaps in GBP, and remain active in EUR, where they clear at LCH.
Worked example, illustrative:client receives 4.19% fixed on GBP 50,000,000, 3x6market 4.20% / 4.22%SR3 future 95.79margin 1 bp, about GBP 1,250hedge buy 50 SR3period SONIA 4.05%: client receives GBP 17,694

The quote comes off the futures strip; the deal is hedged in the futures, confirmed and reported. The period starts three months later with nothing to exchange, and ends three months after that with one payment: the difference between the locked rate and the compounded rate on the notional for the period.
Notation: 3x6 means the period starts in 3 months and ends in 6; the buyer of a FRA pays fixed and gains when rates rise, the seller receives fixed; dealers quote the forward rate as a two-way price straight off the futures strip or the swap curve.
SONIA versus SONIA: a SONIA FRA fixed on the fixing date two days before the period and settled on the first day, discounted at the fixed rate; a SONIA single-period swap can only settle after the period, because the compounded rate is known on its last day.
Clearing: SONIA FRAs are rare; the sterling FRA market ended with SONIA; SONIA FRAs are not (the market moved to futures and OIS); EURIBOR and GBP FRAs remain and clear at LCH; bilateral FRAs sit under the ISDA with VM.
Uses today: locking a reinvestment or funding rate for one period, hedging a loan reset, and the building block of the forward curve: a strip of FRAs or SONIA futures is a swap.
A basis swap exchanges one floating rate for another plus a spread. It carries almost no duration, only the spread between two funding markets, so it is used by banks whose assets and liabilities reset off different benchmarks. Traded on an MTF or OTF, cleared like a standard swap, settled quarterly on the difference of two compounded rates.
Worked example, illustrative:client pays SONIA, receives the overnight rate + basis, GBP 500,000,000, 2 yearsmarket 5.0 / 6.0 bpclient the overnight rate + 4.5 bpmargin 0.5 bp, about GBP 50,000 PVquarter SONIA 4.30%, the overnight rate 4.25%: about GBP 6,300 netcleared LCH or ICE Futures Europe, voluntary

The cleared swap lifecycle with two floating legs: MTF, CCP, trade repository, quarterly net payment and daily margin. The desk hedges the basis in the interdealer market or across the two futures strips. The amounts are small; the risk being managed is a funding mismatch.
United Kingdom: the sterling basis market shrank to almost nothing when LIBOR ended in 2021; the trades left are term SONIA against SONIA for the loans that use the term rate, small and mostly bilateral, and the cross-currency basis (SONIA against SOFR) for the funding desks; the cleared leg is the SONIA swap at LCH SwapClear.
Basis swaps exchange two floating rates: SONIA versus the overnight rate (the main GBP one since SONIA), 1-month versus 3-month term rates where they still exist, UK Treasury bill versus SONIA; cross-currency basis swaps are the two-currency version (see Cross-Currency Swap).
The basis between SONIA and the overnight rate is the price of the difference between secured gilt repo funding (SONIA) and unsecured interbank funding (the overnight rate); it widens at quarter ends and when repo markets tighten, as in September 2019.
Users: banks with covered bond advances (indexed to SONIA) against fed-funds-linked assets, money funds and dealers managing the two futures strips, and anyone moving a hedge from one benchmark to the other.
Both legs compound daily and settle quarterly through the CCP; the UK EMIR clearing obligation covers SONIA swaps; SONIA’s end in 2021 moved the sterling swap market to SONIA compounded in arrears.
An inflation swap is the derivative form of inflation protection. One payment at maturity: the client receives the cumulative growth of CPI-U and pays a fixed compounded rate. The lifecycle is a cleared swap with no coupons, only variation margin, and with a monthly external event, the CPI print, that moves the mark.
Worked example, illustrative:client receives inflation USD 100,000,000, 10-year zero couponmarket 2.45 / 2.50client fixed 2.48%margin 0.5 bp, about USD 43,000 PVrealized CPI 2.70%, ratio 1.3050maturity net USD 2,741,099 to the client

The desk quotes off the interdealer inflation curve and inflation-linked gilts breakevens, clears the trade at LCH, and hedges with an offsetting swap or a inflation-linked gilts-versus-nominal breakeven position. For ten years the only cash flows are daily variation margin as CPI prints and the curve move. At maturity the realized CPI ratio is compared with the compounded fixed rate and one net amount is paid.
United Kingdom: the sterling inflation swap market (RPI, with CPI and the 2030 alignment of RPI to CPIH) is deep, with the index-linked gilts as the cash market and the pension schemes’ LDI mandates and the insurers as the receivers; the swaps are bilateral under UK EMIR or cleared at LCH SwapClear.
The USD inflation market: zero-coupon swaps are the interdealer standard; year-on-year swaps and inflation caps and floors trade for structured products. Liquidity is a fraction of the rates market, so bid-offers are 3 to 5 bp wide.
Indexation uses CPI-U NSA with a 3-month lag, the same convention as inflation-linked gilts, so inflation-linked gilts are the natural hedge: long inflation-linked gilts and short nominals replicates receiving inflation, less the asset-swap basis.
Clearing is voluntary but standard: LCH SwapClear and CME both clear USD inflation swaps; initial margin is higher than for rates swaps. Trades are reported to the trade repository like any swap.
Users: pensions and insurers with inflation-linked liabilities receive inflation; utilities and real-estate owners with inflation-linked revenues pay it; dealers warehouse the gap and hedge in inflation-linked gilts.
A cross-currency swap is an FX swap stretched over years with floating interest in between: principal is exchanged at the start, each party pays the other’s floating rate on the principal it holds, and the principal is swapped back at maturity at the original rate. The price is the basis, the premium for borrowing USD through the swap market. It is the tool for turning a bond in one currency into funding in another, and it stays bilateral for its whole life.

The client gives EUR and takes USD at spot, pays SOFR on the USD, receives ESTR less the basis on the EUR, and gets its EUR back at maturity to repay the bond. The bank hedges the basis with another dealer and runs the two floating legs in its OIS books. The distinctive risk is on the principal: five years of FX moves on EUR 500m, covered by daily variation margin and priced with CVA.
The basis is the spread added to the non-USD leg so that the swap prices at par; it is negative when USD funding is scarce (−50 bp and beyond at the 2008 and March 2020 peaks) and widens at quarter and year ends. Dealers quote it as a spread on the EUR (or JPY, GBP) leg against SOFR flat.
Users: corporates and sovereigns issuing where demand is best and swapping into their home currency (reverse Yankees, Yankee bonds), banks funding USD assets from EUR or JPY deposits, and asset managers hedging foreign bonds for longer than FX forwards allow.
Documentation and regulation: ISDA with CSA; a UK EMIR swap, reported to the trade repository, not mandated to clear and almost always bilateral; the uncleared-margin rules require daily VM, with the fixed physically settled FX principal exchange exempt from IM.
Interdealer trades reset the USD notional every quarter (mark-to-market cross-currency swaps) to keep the credit exposure small; client trades usually do not, so the bank’s credit line and CVA carry more weight on this product.

Valuation Adjustments on an Uncollateralized Swap
When a client trades without posting collateral, three internal transfers take place. The rates desk owns the market risk; a central xVA desk charges for and hedges the counterparty credit risk (CVA), the funding cost of the asymmetric hedge (FVA) and the regulatory capital the trade consumes (KVA). The client sees one price; the bank sees three internal transfers.
Worked example, illustrative:client pays fixed GBP 200,000,000, 7 years, no CSAmid 3.90%CVA 9 bpFVA 4 bpKVA 3 bpdesk margin 2 bpclient rate 4.08%client spread CDS 150 bp, recovery 40%

Jump to17 steps, hover or click any of them
Before quoting, the rates desk asks the xVA desk for the incremental cost of the trade on the client’s netting set; the charge is added to mid. Once dealt, the rates desk pays the charge to the xVA desk and hedges its rates risk in the cleared market; the xVA desk hedges the client’s credit with CDS and runs the funding and capital. For seven years the exposure builds and runs off while both desks re-hedge daily.
CVA = expected loss from the counterparty’s default, priced off its CDS spread (or a proxy by rating and sector), its expected positive exposure profile and recovery. DVA is the mirror on the bank’s own default; FVA the cost of funding uncollateralized derivatives; KVA the cost of capital; MVA the cost of initial margin on cleared or bilateral hedges.
Why a central desk: counterparty risk is a portfolio quantity (netting across a client’s trades) and needs credit hedging skills the rates desk does not have; charging at inception and transferring the risk keeps trading desks’ P&L clean of credit moves.
Corporate end users hedging commercial risk may elect the exception from mandatory clearing (FCA rule 50.50), so uncollateralized swaps still exist; financial counterparties must clear and post margin.
Accounting (ASC 820 fair value) requires CVA and DVA in the fair value of derivatives; Basel III adds a CVA capital charge for the volatility of CVA. The two measures differ, and the desk hedges one while reporting both.
Gilts are the UK government’s bond market, about £2.5 trillion outstanding, traded on a price basis in decimals. The bank makes markets to clients on request-for-quote platforms and hedges on the interdealer order books (S); as a primary dealer (the gilt-edged market maker) it also bids at auction for itself and its clients and distributes the award (P). Interdealer trades are netted at LCH Ltd; everything settles delivery versus payment on CREST on T+1.

S: the client puts dealers in competition and trades at the interdealer offer; the bank earns its margin from skewing its quote around inventory and from financing its book. P: gilt announces, the market trades the note when-issued, bids go in through the DMO’s auction at 13:00, and the award is passed to clients and distributed into the WI shorts. Both routes end at LCH Ltd netting for the interdealer legs and DVP settlement on CREST for everything.
United Kingdom: the DMO issues through auctions and syndications with the gilt-edged market makers (and the post-auction option facility); the secondary market is the GEMMs’ screens and the dealer-to-client platforms (Tradeweb, Bloomberg); settlement at CREST on T+1; the Bank of England’s gilt sales under quantitative tightening and the pension schemes’ LDI demand are the other side of the market.
Gilts settle T+1 in CREST, run by Euroclear UK & International with DVP in central bank money through the Bank of England’s RTGS; the bank is a CREST member with a settlement bank providing the cash, or holds through a custodian.
LCH Ltd RepoClear novates and nets dealer-to-dealer gilt cash and repo trades; its CCP guarantee and netting cut the CREST deliveries by over 70%. There is no clearing mandate for gilts or repo in the UK; the balance sheet cost of bilateral repo moves the market there, and buy-side clients access LCH Ltd as sponsored members or through an agent member.
The gilt-edged market makers (about 17 firms) must bid at every auction and make continuous two-way prices, and in return get the post-auction option facility and the DMO’s and the Bank of England’s operations. Conventional gilt auctions are bid-price (every accepted bid pays its own price), index-linked auctions uniform-price. Clients bid through a GEMM; non-GEMMs can apply non-competitively through the DMO’s approved group.
Prices are in decimals to three places, with the yield to three decimals beside them. Hedging is done in DV01 terms: the desk hedges a 10-year with the long gilt futures or other maturities and runs the curve risk that remains.
Fails: a delivery not made on settlement date carries no cash penalty in the UK; the failing party funds the other side’s position in repo, CREST’s partial settlement and the GEMMs’ market practice keep fails short, and the DMO’s standing repo facility lends a squeezed gilt against cash.
inflation-linked gilts are gilts whose principal grows with CPI-U. They trade like nominal notes on the same platforms and settle the same way, with one twist at every cash event: par is multiplied by an index ratio derived from the CPI published three months earlier. The desk’s risk splits into a real rate and a breakeven inflation rate, hedged separately.

The RFQ, execution, Trade report, LCH Ltd netting and CHAPS DVP are those of a nominal gilt. What changes: the quote is a real yield, the settlement amount carries the index ratio, the coupon and the principal are inflation-adjusted, and the hedge has two legs: nominals for the real rate and inflation-linked gilts or inflation swaps for the breakeven.
United Kingdom: the index-linked gilts are linked to the RPI with a three-month lag (the RPI aligns with CPIH from 2030), issued by the DMO and held mostly by the pension schemes and the insurers; the break-even trades against the nominals and the inflation swaps, and the linker market is the largest in the world relative to the sovereign curve.
Indexation: the reference CPI for a date is interpolated between the CPI-U NSA of three and two months earlier; the index ratio is the reference CPI on the date divided by the reference CPI on the issue date. gilt publishes daily index ratios per ISIN.
Breakeven inflation = nominal yield − real yield of the same maturity; it is the market’s inflation expectation plus a risk premium less a liquidity premium. The desk hedges breakeven risk with inflation-linked gilts of other maturities, inflation swaps or the inflation-linked gilts futures basis.
inflation-linked gilts are issued at 5-, 10- and 30-year maturities, about GBP 2 trillion outstanding, auctioned like nominals (yield-based, single price) with a reopening schedule; they are LCH Ltd-eligible and repo-able.
Deflation floor: at maturity the holder receives at least the original par; coupons have no floor and fall with the index ratio in deflation. Seasonality in CPI makes short inflation-linked gilts carry volatile month to month.
Agency and Supranational Debt in Sterling, the EIB, KfW and the World Bank
Agency debentures are the debt of the supranationals and the UK the agencies and supranationals (the EIB, the World Bank, Transport for London, the housing associations): gilt-like settlement on CREST, a spread over gilts for the implied guarantee, and a daily primary market of callable notes built to order. A bullet (B) trades and settles like a gilt with a spread; a callable (C) is a bullet plus a swaption the investor sold to the issuer for extra coupon, and the bank hedges that option.
Worked example, illustrative:B, client buys GBP 50,000,000 covered bond 3-year bullet at gilt + 14.5 bp, 99.85B, market gilt + 16 / 14B, margin 0.5 bp, about GBP 7,000C, client buys GBP 100,000,000 5nc1 callable at 5.30%, at parC, bullet equivalent 4.50%, plus about 80 bp for the optionC, outcome called at par after year 1 when rates fell

Two routes to the same settlement rail: the bullet is a secondary RFQ with a gilt hedge; the callable is a reverse inquiry the bank turns into a new issue with the agency, hedged in the swaption market. Both settle DVP on CREST and net at LCH Ltd between dealers; the callable usually ends early, when the issuer exercises the option it bought.
United Kingdom: the supranationals and the foreign agencies issuing in sterling, with explicit or implicit state guarantees, are the UK agency market, traded like the gilts; there is no domestic agency issuer of size since Network Rail stopped issuing, and callables are rare.
The issuers: the EIB and the EIB (in conservatorship since 2008), the national promotional banks (the largest, funding their member banks), Farm Credit; about GBP 2 trillion of debentures and discount notes outstanding, 20% risk-weighted and HQLA for banks.
Bullets trade like gilts at a spread (agency spreads of 10 to 30 bp), settle on CREST, net at LCH Ltd and are hedged with gilt futures; discount notes are the money-market end (see Money Markets, Treasury Bills).
Callables: issued daily by reverse inquiry through selling-group dealers, in Bermudan, European and American styles; the investor earns the option premium as coupon, the issuer swaps the callable to floating with a swaption from the dealer, and the dealer hedges the swaption; most are called within a few years when rates fall.
The implied guarantee: agency and supranational debt (the EIB, the World Bank, the housing associations) carries no explicit gilt backing; the conservatorships and the Treasury’s support agreements make it near-sovereign in practice; covered bond debt is the joint and several obligation of the 11 banks.
Sovereign and Supranational Bonds, SSA and Emerging Markets
Government-related dollar bonds come in two kinds. Supranationals, sovereigns and the agencies and supranationals (SSA: the World Bank, EIB, KfW, Canadian provinces) are AAA swap-spread products traded in size on tiny margins and settled in CREST or Euroclear. Emerging-market sovereigns are credit products quoted over gilts, hedged with sovereign CDS, and settled in Euroclear for the Reg S line. Both print to the APA.
Worked example, illustrative:S, client buys GBP 25,000,000 AAA supranational 5-year at swaps + 20.5 bp, price 99.79S, margin 0.5 bp, about GBP 6,000S, settlement T+1 in CRESTE, client buys GBP 25,000,000 BB sovereign 2035 at 96.60, gilt + 260 bpE, CDS 180 bpE, margin 10 cents over mid, GBP 25,000E, settlement T+2 in Euroclear

The same RFQ leads to two different operating models. The SSA route is priced off the swap curve, hedged with a swap and settled at CREST; the emerging-market route is priced off gilts and the country’s CDS, hedged in both, and settled in Euroclear. The two depositories and the two settlement cycles are the main operational difference.
United Kingdom: the SSA market in sterling is the supranationals and agencies that issue in pounds (the EIB, KfW, the World Bank, the Nordic agencies) and the UK’s own public issuers (Transport for London, the housing associations, the devolved governments), traded like the gilts and settled at CREST and the ICSDs; the emerging markets business runs through the global desks.
SSA: supranationals, sovereigns (non-US, in GBP), the agencies and supranationals and provinces issue GBP benchmarks of GBP 3 to 6 billion through syndicates of banks, priced as a spread to mid-swaps; the paper is 0% risk-weighted and HQLA, so bank treasuries and central banks hold it, and dealers make markets on a basis point or less.
Emerging-market sovereigns issue in GBP under New York or English law, usually in a 144A/Reg S format with two lines; trading is quoted in price and spread to gilts, EMBI is the index, and sovereign CDS (cleared at ICE) is the hedge; sanctions screening is part of onboarding for some countries.
Settlement: CREST for the 144A line and for most SSA global notes (with a bridge to Euroclear), Euroclear and Clearstream for Reg S lines on T+2; Europe moves to T+2 in October 2027. The bank keeps GBP cash accounts at the ICSDs through a correspondent to fund its deliveries.
Risk: SSA is swap-spread risk and new-issue underwriting risk; EM is country risk, a default ending in an exchange offer under collective action clauses, and liquidity that can disappear in a crisis.
Corporate bonds trade in an over-the-counter market made by dealers out of inventory, increasingly on electronic request-for-quote platforms. The bond is quoted as a spread over gilts, the trade is printed on the APA within minutes, matched with the client’s custodian the same day and settled delivery versus payment at CREST on T+2. The desk’s risk is split into rates (hedged with gilts) and credit spread (hedged with CDS or run).

The client puts five dealers in competition; the bank wins by selling from inventory at a spread two basis points inside where it bought. The trade is printed to the market on the APA, allocated to funds and matched through CTM, and settled against payment at CREST the next day. The bank’s remaining inventory is financed in repo and its spread risk hedged in CDS.
United Kingdom: sterling corporate bonds settle at the ICSDs or at CREST, traded by RFQ on MarketAxess, Tradeweb and Bloomberg or by voice; the dealer publishes the trade through an APA under the FCA’s bond transparency regime (reformed in December 2025) and reports the transaction to the FCA; the Bank of England’s corporate bond holdings were sold back by 2024; the bond consolidated tape is the first UK tape.
Market structure: about 45% of IG volume is electronic (MarketAxess, Tradeweb, Bloomberg), mostly RFQ to several dealers and increasingly all-to-all and portfolio trades; the rest is voice and chat. Dealers hold far less inventory than before 2008.
The APAs make the corporate bond trades public under the FCA’s regime of December 2025 (real time for the liquid bonds, deferred by size and liquidity for the rest); the transparency keeps spreads tight and the margin in basis points, not points.
Settlement: sterling corporate bonds settle T+2 at the ICSDs or in CREST. Institutional trades settle DVP trade for trade after CTM matching; dealer-to-dealer trades stay bilateral or net through the CCP where the bond is eligible.
Risk: a corporate bond is a gilt plus a credit spread. The desk hedges the gilt leg mechanically and manages the spread leg as a book: iTraxx index hedges for beta, single-name CDS for large positions, and the carry on inventory financed in repo.

Corporate Bond New Issue, Bookrunner
The primary market is where a bond comes into existence. The issuer mandates a syndicate; over one day the banks announce, build a book of investor orders, tighten the price, launch, allocate and price. The bank underwrites (commits to buy the bonds) and distributes them; the bonds are born at the ICSDs on closing day and delivered against payment to the allocated investors.

One day from announcement to pricing: initial price thoughts attract orders, guidance tightens them, launch fixes the spread, allocation decides who gets what, and the DMO spot sets the coupon. The bonds then settle into CREST against payment a few days later, and the deal moves from the syndicate desk to the secondary desk, which supports it in the market.
United Kingdom: the sterling Eurobond new issue is led by the banks’ syndicate desks, priced in a day from the initial price talk, documented under the issuer’s EMTN program with a prospectus approved by the FCA or the wholesale exemption, allocated under the FCA’s allocation rules and settled at the ICSDs; the sterling market is a fraction of the euro and dollar markets, with the long end the pension schemes’ and insurers’ demand.
Roles: bookrunners run the book and allocate; co-managers get a small fee for distribution; the billing and delivering bank handles settlement. Fees for IG are 35 to 65 bp depending on tenor, HY 1.25% to 2%.
Documentation: an EMTN program with a base prospectus approved by the FCA, or a standalone Eurobond; a 144A tranche for US investors; the prospectus, comfort letters and legal opinions are delivered at pricing and closing. Ratings are confirmed before announcement.
Pricing moves in steps: IPTs, guidance, launch, then the gilt benchmark is spotted and the coupon and price follow. The new-issue concession (a few bp cheap to secondary) is what makes the bonds trade up in the grey market.
Underwriting risk: in a bought deal or if the book collapses, the banks own the bonds. Allocation favors long-term holders over fast money; regulators (the FCA’s rules for equities, conduct rules for debt) watch for abuses.
Below investment grade the bond market changes character: prices instead of spreads, 144A documentation, thin single-name hedges, capital structures that determine recovery, and issuers that default. A performing high-yield bond (H) trades and settles like a corporate with wider margins and index hedges; a defaulted bond (D) trades flat on its expected recovery and ends in a bankruptcy plan that exchanges it for new securities.
Worked example, illustrative:H, client buys USD 10,000,000 B-rated 7.25% 144A at 92.25H, run 91.50 / 92.50H, yield to worst 9.1%, callable at 103.625H, margin about USD 25,000D, client buys USD 10,000,000 face of a defaulted bond at 45.50 flatD, bid 44.50D, recovery new notes and shares worth 52 on the plan’s effective date

Two routes that share the back end: both print on TRACE and settle DVP at DTC on T+1. The high-yield route is priced off the capital structure and hedged with the index; the distressed route is priced off the recovery and ends in a Chapter 11 distribution through DTC. Claims that are not securities (bank debt, trade claims) leave DTC and settle by assignment, slowly.
United Kingdom: the sterling and European high yield market is a Eurobond market settled at the ICSDs, with the restructurings under a restructuring plan (Part 26A) or a scheme of arrangement in the English courts; the diagram keeps the US market the bank also trades.
Market: about USD 1.4 trillion of US high-yield bonds, mostly 144A with registration rights, callable after a few years, held by mutual funds, ETFs, insurers and CLOs through loans; trading is voice and chat with a growing electronic share (MarketAxess, Trumid); dealers hold little inventory.
Pricing and conventions: quoted in price with yield to worst (the lowest yield across the call dates); TRACE caps high-yield prints at USD 1 million; a bond trades flat after a missed coupon or a default, so no accrued interest changes hands.
Distressed: the desk values the claim through the restructuring (absolute priority, the fulcrum security, DIP loans, exchange offers, Chapter 11 plans); information barriers separate the private-side (creditor committee) and public-side desks; non-security claims settle on LSTA distressed documentation by assignment or participation.
Risk: single-name CDS exists for the largest names only, so the book is hedged with CDX HY and managed as a portfolio of issuers; liquidity risk (a fund forced to sell into a thin bid) is the main one, and the reason the desk’s bid is wide.
A credit default swap is insurance-like protection against a borrower’s default, paid for with a running coupon. Two different lifecycles under one product name: the index (K) is a liquid, standardized contract that must be traded on an MTF or OTF and cleared at ICE Clear Credit; the single name (B) is a bilateral contract under the ISDA, thinly traded, with collateral moving between the two parties and, in the rare case, a credit event settled by auction.
Worked example, illustrative:K, client buys protection USD 100,000,000 CDX IG 5-yearK market 52.0 / 52.5 bpK client 52.5 bp; coupon 100, upfront to client about USD 2.2mK margin 0.25 bp, about USD 11,000B, client buys protection USD 25,000,000 single-name BBB 5-yearB market 180 / 190B client 192 bp; upfront USD 979,200credit event recovery 35%, pays USD 16.25m

Both routes start with a spread quote and convert it into a standard coupon plus an upfront payment. K then goes to the trading venue, to the CCP and into the margin cycle; B stays between the two parties with CSA collateral and the trade repository report. Both pay a quarterly coupon on IMM dates. The index rolls to a new series twice a year; the single name waits for a credit event that usually never comes, and if it does, an ISDA auction fixes the payout.
United Kingdom: the iTraxx indices clear at ICE Clear Credit or LCH SA CDSClear under the UK EMIR clearing obligation and the single names are bilateral or cleared voluntarily; both sides report under UK EMIR; the diagram keeps the US index for comparison.
Conventions since the 2009 Big Bang: fixed coupons of 100 bp (IG) or 500 bp (HY) with the difference to the traded spread paid upfront; quarterly IMM dates; the ISDA 2014 definitions; credit events decided by the Determinations Committee and settled by auction.
CDX IG (125 investment-grade names) and CDX HY (100 names) roll into a new series every March 20 and September 20; the on-the-run series carries most of the liquidity. Index CDS are FCA swaps, made available to trade and cleared at ICE Clear Credit (which clears over 95% of cleared CDS).
Single-name CDS are derivatives reported under UK EMIR regulated by the FCA: reporting to a security-based swap data repository, dealer registration, and FCA uncleared-margin rules; clearing at ICE is available for the liquid names but voluntary.
The bank’s credit desk uses CDS to hedge bond inventory (the basis between cash bonds and CDS is a trade in itself), the xVA desk uses them to hedge counterparty risk, and the index is the beta hedge for the whole credit book.
Leveraged loans are syndicated bank loans traded like securities but settled as contracts: there is no CUSIP-based depository, no DVP and no T+1. A trade is settled by assigning the lender’s rights under the credit agreement through the administrative agent, which takes days to weeks, and the LSTA’s delayed-compensation rules keep the economics honest in the meantime.
Worked example, illustrative:client buys USD 10,000,000 term loan B, B-ratedmarket 98.50 / 99.00client 99.00margin half a point, USD 50,000coupon SOFR + 350 bptarget settlement T+7, par/near-paractual T+10 to T+20agent fee about USD 3,500

The quote and the trade resemble a bond trade. The rest of the lifecycle differs: an LSTA confirmation on ClearPar, an assignment agreement that the agent bank and sometimes the borrower must approve, a lender register update, and a wire of the purchase price that is not linked to the transfer. Delayed compensation accrues from T+7 so that slow settlement does not reward either side. Interest and principal flow through the agent, not a depository.
United Kingdom: the UK and European leveraged loan market runs on LMA documentation from London, with the agent banks and the CLOs as the buyers and settlement by assignment in weeks; the diagram keeps the US market the bank also trades.
The US leveraged loan market is about USD 1.4 trillion of outstanding term loans, mostly held by CLOs, loan funds and banks. Loans are floating rate (SOFR plus a margin), senior secured, prepayable at par, and traded over the counter by dealer desks in price terms.
Settlement by assignment makes the buyer a lender of record under the credit agreement; participation is the alternative (the seller stays the lender and passes the economics through) when consent is refused or for speed. Settlement averages 15 to 25 days; the LSTA’s T+7 target and delayed-compensation rules push it shorter.
Information: a loan desk may receive private (non-public) borrower information as a lender; trading desks sit on the public side and screen for material non-public information. Loans are not securities under US law, so the trading rules differ from bonds.
Clearing: there is no CCP or central depository; ClearPar (IHS Markit, now S&P) is the settlement platform for documents and the funding memo, and the agent bank keeps the register. DTC’s role is limited to the loans that are CUSIP-bearing.
Municipal Bonds, Competitive Sale and Secondary (US Market)
Municipal bonds are the USD 4 trillion tax-exempt market: debt of states, cities and authorities, mostly held by individuals directly or through funds and separately managed accounts. Two routes: the bank underwrites a new issue by winning a competitive sale (P) and reoffers the bonds to its clients, or sells from inventory in the secondary market (S). Reporting goes to the MSRB instead of FINRA, and settlement is DTC on T+1 like a corporate bond.
Worked example, illustrative:P, issuer USD 300,000,000 GO, 20 serial maturities, 5% couponsP, winning bid TIC 3.68%, by 1 bpP, client USD 5,000,000 of the 2036 at 3.05%, price 116.66P, underwriting spread USD 5.00 per bond, USD 25,000S, client buys USD 5,000,000 of the same bondS, MMD AAA 10y 2.90%S, client 3.10%, price 116.20, markup about USD 23,000settlement S: T+1; P: closing about two weeks after the sale

On the primary route the issuer publishes a notice of sale, the bank prices a scale, bids a true interest cost through the Parity platform and wins; it then reoffers each maturity to investors and pays the issuer at closing two weeks later, when the bonds are born at DTC. On the secondary route the desk offers from inventory against the MMD curve and the MSRB tape, and settles T+1. Both routes print to RTRS within 15 minutes and pay coupons through DTC.
United Kingdom: the US municipal market has no UK counterpart, so the diagram keeps it for comparison; UK local authorities borrow from the Public Works Loan Board, and the housing associations, the universities and Transport for London issue sterling bonds through the banks’ syndicates, traded like the agencies.
Munis are exempt from federal income tax (and usually state tax in the state of issue), so they yield less than Treasuries: the 10-year muni-to-Treasury ratio is the market’s core relative-value measure, around 65% to 75% most of the time. The MMD AAA scale (Refinitiv) is the benchmark curve every trade is priced off.
Primary market: competitive sales (the issuer takes the lowest true interest cost from sealed bids, common for GO bonds) and negotiated sales (the issuer picks a senior manager who runs a bookbuild, common for agency bonds and large deals). Underwriting spreads are USD 3 to 7 per bond; closing is two to three weeks after the sale.
Regulation: the MSRB writes the rules (G-15 confirmations with markup disclosure, G-17 fair dealing, G-32 new-issue disclosure) and FINRA and the SEC enforce them; trades are reported to RTRS, not TRACE, and displayed on EMMA with the official statements and continuing disclosures. Issuers are exempt from SEC registration but underwriters must ensure disclosure under Rule 15c2-12.
Structure: serial maturities (one CUSIP per year) and term bonds with sinking funds; 5% coupons priced at a premium to a par call in year 10 are the convention, because the call protects the issuer and the premium protects the investor from the de minimis tax rule on market discount. Settlement moved to T+1 with the rest of the US market in May 2024.
An asset swap is a bond and a swap sold as one package: the client buys the bond and swaps its fixed coupon into floating, so it holds the issuer’s credit at a spread over SONIA without the interest-rate risk. The bank sells the bond from one desk and the swap from another, clears the swap and settles the bond at CREST. The asset swap spread is the market’s price for the bond’s credit relative to the swap curve.
Worked example, illustrative:client buys GBP 25,000,000 7-year 4.50% A bond at 97.50, swapped to floating7y swap 3.78%ASW market 112 / 108 bpclient receives SONIA + 108 bp, pays 4.50%margin 2 bp, about GBP 30,000 PVpackage par: 97.50 for the bond plus 2.50 upfront into the swap

One quote, two trades: the bond settles DVP the next day; the swap starts on the same date with an upfront that brings the package to par, is cleared at LCH and runs to the bond’s maturity. The client receives the coupon on the bond and pays it away on the swap, keeping SONIA plus the spread. If the issuer defaults, the swap survives and the client is left paying fixed on a bond that stopped paying.
United Kingdom: the asset swap is a SONIA swap against the bond; the bank’s swap desk clears the swap at LCH SwapClear and holds the bond at the ICSD or CREST.
Par versus market asset swap: in a par asset swap the client pays 100 for the package and the difference to the bond’s price goes into the swap as an upfront; in a market asset swap the client pays the bond price and the swap notional is set to that price. Par is the convention for quoting the spread.
The asset swap spread is the oldest credit spread measure: the bond’s yield over the swap curve, adjusted for the price; the z-spread and the CDS basis (asset swap spread versus CDS spread on the same name) are the trades built around it.
Users: bank treasuries and insurers that fund floating and want credit carry; dealers packaging new issues for investors; CDS basis traders. Floating-rate note investors get the same economics without the swap.
The swap is a standard tax authority with an odd fixed coupon and dates, so it clears like any swap and stays alive after a default; the package indicator in the trade repository report tells the regulator the two trades were priced together.
The USD 9 trillion agency mortgage market trades mostly as TBAs (to-be-announced forwards): a forward contract on a generic pool with a known agency, coupon, term and settlement month, but unknown specific pools until 48 hours before delivery. The lifecycle adds a monthly settlement calendar, netting at FICC MBSD, a pool allocation step, the dollar roll as a financing trade, and the agency’s factor and remittance cycle after settlement.
Worked example, illustrative:client buys USD 100,000,000 FNMA 30y 5.5% TBA, next monthscreen 99-24 / 99-25client 99-25+margin half a tick, about USD 15,600roll 6/32 front minus back monthVM 1 point = USD 1msettlement the retail class date, Fedwire Securities DVPgood delivery 0.01% variance per million, 3 pools max

Buyer and seller agree the generic terms today and the settlement date next month; FICC MBSD nets all the bank’s TBA positions per coupon and month, and daily variation margin covers the forward exposure. Two days before settlement the seller announces the pools; on the SIFMA date they move on Fedwire Securities against payment. The client can instead roll into the next month; the roll is also how dealers finance mortgage inventory.
United Kingdom: the bank’s US dealer trades the TBA market in New York and the diagram keeps the US infrastructure; UK mortgages fund through covered bonds under the regulated covered bond regime and RMBS, with no forward market.
TBA eligibility: pools must meet the agency’s and SIFMA’s good-delivery guidelines; cheapest-to-deliver pools (high loan balance, seasoned, investor loans) are what a seller delivers into a TBA, so specified pools trade at a payup over TBA (see Specified Pools).
SIFMA publishes the settlement calendar: the retail class (30-year FNMA and FHLMC UMBS) around the 12th, Class B (15-year) around the 17th, the retail class with trailers (GNMA) around the 20th. Notification is two business days before, by 15:00 ET.
FICC MBSD is the CCP for TBAs: it nets positions, guarantees settlement and runs EPN, the electronic pool notification system. Members post margin to MBSD; non-members face the dealer bilaterally under an MSFTA with margin (SIFMA best practice since 2014, effectively mandatory).
The dollar roll: selling the front month and buying the back month is economically a secured financing of the pools. The implied financing rate compared with repo tells whether the roll is trading special, which happens when the Fed or large buyers hoard the front month.
Risk: an MBS is a bond with a prepayment option held by millions of homeowners. The desk hedges duration with Treasuries and swaps, convexity with swaptions, and runs the OAS (option-adjusted spread) basis as its P&L.
Specified pools are the other half of the agency market: trading actual pools by CUSIP, priced as the TBA plus a payup for characteristics that slow prepayments (low loan balances, certain states, seasoning). Settlement is like a Treasury, T+1 DVP on Fedwire Securities; the hedge is a TBA sale, so the desk is left owning the payup.
Worked example, illustrative:client sells 10 pools, USD 80m original face, FNMA 5.0% low balanceTBA reference 97-12payup +1-08 low balance, +0-12 othersawarded 6 pools, USD 50m original, 41.5m current at factor 0.83settlement USD 40.78m plus accrued, T+1 DVPhedge sell USD 41.5m TBA at 97-12

An insurer puts pools out for bid; the desk runs its prepayment model and bids each pool as TBA plus a payup; it wins six, hedges them by selling TBA, and takes delivery on Fedwire Securities the next day. From then on it owns the difference between how these pools prepay and how the generic TBA prepays, until it resells them or delivers them into its TBA short.
United Kingdom: a US market kept for comparison; the UK mortgage bond trade is in the regulated covered bonds and the RMBS master trusts of the large lenders, traded as bank debt.
Payups compensate for prepayment protection: a borrower with a USD 85,000 loan refinances less often than one with USD 500,000, so low-loan-balance pools prepay slower and are worth more when rates fall. Other stories: geography (New York, Texas), investor property, high LTV, seasoning.
Settlement amount on a pool = original face × current factor × price / 100 + accrued; factors are published monthly and the amount is recomputed if settlement crosses a factor date.
Specified pools also trade on an all-in price basis and in CMO form (REMIC tranches cut from pools); CMOs settle at DTC or Fedwire depending on the issuer and bring their own structure risk (PAC, support, IO, PO).
The desk’s book: long pools, short TBA, financed in repo (agency MBS are high-quality collateral at 2% to 3% haircuts). The P&L is the payup move and the carry; the risk is model risk on prepayments.
Agency CMO, REMIC Structured From Pools (US Market)
Agency CMOs are the structuring side of the agency market: the desk buys pools, hands them to an agency trust and sells back the same cash flows re-cut into tranches with different prepayment profiles, planned amortization classes for investors who want a predictable schedule and a support class for those paid to take the variability. The deal lives on Fedwire Securities like the pools it was made from, and pays monthly through the agency’s waterfall.
Worked example, illustrative:collateral USD 500,000,000 FNMA 30y 5.5% at 99-20PAC 1 USD 150m, 3y WAL, 100-24PAC 2 USD 200m, 10.7y WAL, 100-08, swaps + 163support USD 150m, 98-24PAC band 100 to 250 PSAdeal profit about USD 1,000,000, 0.2 pointsettlement monthly agency date, Fedwire Securities DVP

Three investors want three different things from the same mortgage cash flows; the desk buys the collateral, designs the tranches so the proceeds exceed the cost, and files the REMIC with the agency, which guarantees the classes and issues them on the settlement date against the pools. From then on the agency pays the waterfall every month; the PACs get their schedule while the support absorbs the prepayment surprises, and the desk trades all three in the secondary market.
United Kingdom: the diagram keeps the US market; the UK structuring business is the covered bond program and the RMBS and CLO tranching under the UK securitisation rules.
A REMIC (real estate mortgage investment conduit) is the tax vehicle: the trust holds the pools and issues classes without being taxed itself. Agency REMICs (Fannie Mae, Freddie Mac, Ginnie Mae) carry the agency guarantee and are Fed-eligible book-entry securities; private-label CMOs settle at DTC and carry credit risk as well.
Classes: sequential pay (A then B then C), PACs (a schedule that holds between two prepayment speeds), TACs, supports or companions, floaters and inverse floaters, interest-only and principal-only strips, Z bonds that accrue. The cash flows always sum to the collateral; structuring moves risk between buyers, it does not remove it.
The arbitrage: tranche proceeds exceed collateral cost when the market pays more for a predictable PAC than it charges for the support, which depends on the shape of the curve and demand from banks and insurers. Desks issue heavily when the arbitrage is open and go quiet when it closes.
Settlement follows the agency MBS calendar: new issues settle on the monthly settlement date, secondary trades T+1 on Fedwire Securities with the factor applied; Trade reporting since 2011; the desk finances inventory in repo at agency haircuts.
Securitization turns a pool of loans into tranched bonds through a trust. The bank structures the deal, places the tranches with investors over one or two days, and the notes are born at CREST on closing day. After that the lifecycle is monthly: the servicer collects, the trustee pays through the waterfall, and investors watch the collateral. Secondary trades settle at CREST on T+2 with a declining factor.
Worked example, illustrative:deal GBP 1.2bn prime auto ABS, tranches A1 to CA2 1-year WAL, talk swaps + 70, priced + 65client GBP 40m order, 30m allocatedclosing T+7 at CRESTfee 25 to 40 bpremittance 15th monthly, sequential waterfallsecondary sold at swaps + 55 six months later

Structuring takes weeks: the cash-flow model, the credit enhancement and the ratings. Marketing takes days: price talk, orders, pricing off the swap curve, allocation. Closing issues the notes into CREST against payment and sends proceeds to the sponsor. Then the trust runs itself: monthly collections, waterfall payments and remittance reports, while the bank trades the bonds in the secondary market.
United Kingdom: UK ABS (the prime and buy-to-let RMBS master trusts, auto and credit card deals from the captives and the banks) are issued under the UK securitisation rules (the FCA’s and PRA’s rulebooks since November 2024) with 5% risk retention, loan-level reporting and the STS label; the tranches are Eurobonds settled at the ICSDs.
US ABS: auto loans and leases, credit cards, student loans, equipment, consumer loans; about GBP 300 billion issued a year. Credit cards use master trusts with revolving periods; autos amortize sequentially. Most tranches are AAA with subordination of 5% to 10%.
Rules since 2008: the UK securitisation rules (loan-level disclosure through a securitisation repository, 5% risk retention, due diligence duties, the STS label) and the CRA Regulation.
Pricing: ABS tranches are quoted as a spread to the interpolated SONIA swap curve at the tranche’s weighted-average life; floating-rate tranches as a discount margin. Secondary liquidity is mostly bid lists (BWICs) and dealer axes.
Operations: a factor-based security like an MBS. The trustee publishes a monthly remittance report; CREST pays P&I to participants; the bank’s surveillance watches triggers (cumulative net loss, delinquency) that can redirect the waterfall.
Bonds backed by commercial mortgages (office, retail, multifamily, hotel), structured in conduits with a senior AAA class protected by 30% subordination. Secondary trading is by bid list and dealer axes, settlement is at CREST on T+2, and the lifecycle after that is the monthly remittance from the master servicer, with a special servicer stepping in for defaulted loans.
Worked example, illustrative:client sells GBP 15,000,000 CMBS conduit AAA, 10-yeardealer runs swaps + 95 / 90bank bid swaps + 92, price 98.75resale swaps + 88margin 4 bp, about GBP 30,000settlement GBP 14.81m plus accrued, T+2 at CRESThedge 7-year swap and CMBX AAA

The desk analyzes the loan pool and the tranche’s protection, bids on the list as a spread to swaps, wins, hedges the duration with swaps and the spread with CMBX, and settles at CREST the next day. The bond sits in inventory, financed in repo, until a client buys it at a tighter spread. Every month the trust reports loan by loan and pays through the waterfall.
United Kingdom: CMBS is a small UK market, issued from Irish or Jersey SPVs under the UK securitisation rules and settled at the ICSDs; the commercial mortgages are mostly held by the banks and the debt funds.
Conduit CMBS pool 50 to 100 loans from several originators; single-asset single-borrower (SASB) deals securitize one large property. Credit support for the last-cash-flow AAA is about 30%; the B-piece buyer takes the first loss and often selects the pool.
Servicing: the master servicer collects and advances, the special servicer takes over loans in default or at risk and decides on modification or foreclosure; the controlling class holder appoints it. Remittance reports (CREFC format) are the surveillance input.
Risk since 2020: office exposure and refinancing risk at maturity (most loans are 10-year balloons); the desk’s hedge is CMBX, a synthetic index on 25 deals per series, which trades more than the cash bonds in stress.
Private-label RMBS (jumbo, non-QM, re-performing loans) follows the same lifecycle at CREST with monthly remittance; agency CMBS (the EIB K, the EIB DUS) settles on CREST like covered bonds and RMBS.
Listed stocks trade on the London Stock Exchange, the MTFs and the systematic internalisers, cleared at the interoperable CCPs and settled at CREST on T+2. The bank either executes as agent, slicing the order through algorithms and earning a commission (A), or prints the block as principal at a discount and works out of the position itself (R). The post-trade and settlement chain is the same.
Worked example, illustrative:A, client buys 500,000 shares, VWAP algo, limit GBP 81A result avg 80.12 vs VWAP 80.10; commission 2 cents, GBP 10,000R, client sells 500,000 shares in one printR risk bid GBP 79.60, 50 bp below lastsettlement T+2 at CREST; matched under the T+1 code’s allocation and confirmation practices on Tthe CCP’s netting one net position per ISIN

A: the parent order passes the pre-trade risk checks and the algorithm feeds child orders to the venues all day; the client pays a commission and owns every fill. R: the client wants certainty now, the desk bids the block at a discount and takes the risk of unwinding it. Both: allocations are matched with the custodian the same evening, the CCP nets the street side, and CREST moves the shares against cash the next day.
United Kingdom: the cash equities desk routes across the London Stock Exchange (SETS), the MTFs and its own systematic internaliser under COBS best execution and the tick size regime, with the transaction report to the FCA and no volume cap on the dark pools since 2023; the risk block is executed under the large-in-scale waiver; the trades clear at LCH Ltd, Cboe Clear Europe or SIX x-clear and settle at CREST on T+2, with stamp duty reserve tax of 0.5% on the purchases.
Market structure: COBS best execution and the UK MiFID venue rules govern the routing; about half of the volume trades away from the London Stock Exchange’s order book, on the MTFs, the dark pools and the systematic internalisers, and every transaction is reported to the FCA through an ARM by the next day.
Settlement is T+2, moving to T+1 on 11 October 2027 alongside the EU and Switzerland; the T+1 code asks for allocation and confirmation on trade date, so CTM matching happens the same evening.
The CCP nets each participant to one position per security per day and guarantees it; CREST holds the shares in dematerialised form in the members’ names (the nominees are the registered holders of most holdings) and moves them by entries against cash in central bank money.
Agency versus principal: as agent the bank owes best execution and earns a commission; as principal it owns the risk and the discount is its compensation. Capital commitment for blocks is the service large asset managers pay for with their agency flow.
Listed options are exchange-traded options on indices and single stocks, cleared at ICE Clear Europe. The bank acts as broker (routing and clearing the client’s order) and often also as market maker on the other side. The lifecycle is premium up front, no margin for the long, daily marks at ICE Clear Europe, and automatic exercise at expiry: cash for index options, share delivery through the CCP for stock options.

The client’s order fills on ICE Futures Europe, partly against the bank’s own market maker in a crossing auction; ICE Clear Europe becomes the counterparty to both. The premium is paid in full on T+2 and the long puts carry no margin. For three months ICE Clear Europe marks everything daily and settles with the clearing member each morning. At expiry the in-the-money puts are exercised automatically and the cash difference is paid out.
United Kingdom: index options on the FTSE 100 (ESX) and equity options on the UK names trade on ICE Futures Europe and clear at ICE Clear Europe; the bank’s dealer is a clearing member and a market maker under ICE Futures Europe’s liquidity provider schemes.
ICE Clear Europe clears the options on ICE Futures Europe, the former LIFFE contracts; the bank’s US options business clears at the US options clearing house. Clearing members post margin on net positions; customers’ margin is governed by the firm’s margin policy and portfolio margin rules.
Index options (FTSE 100, FTSE 250) are cash settled, European style, and taxed as derivatives under the UK rules; stock options are physically settled, American style, and deliver 1,000 shares per contract through ICE Clear Europe.
Market making: the bank’s derivatives desk quotes two-sided markets on the exchanges, hedges delta with futures and stock, and manages a volatility book; the bid-offer and the auction price improvement are the economics.
Weekly FTSE 100 options exist, but the zero-day boom is a US phenomenon; most FTSE 100 option volume is in the monthly expiries. The protective put here is the institutional hedging use; overwriting (selling calls) is the yield use.
Index futures are the fastest way to change equity exposure: one order on ICE Futures Europe moves GBP 250 million of beta. The bank is the clearing member, not the counterparty: it routes the order, clears it as a member of ICE Clear Europe and holds the client’s margin in segregation. Cash variation margin twice a day, a quarterly roll, and cash settlement at expiry.
Worked example, illustrative:client sells 2,800 FTSE 100 futures, £10 per point, about £250m notionalfill 9,000.5commission about £1.00 per contractIM about £5,500 per contract, £15m1 point £28,000 on 2,800 lotsexpiry third Friday, cash to the SOQ

The clearing broker’s risk filter passes the order to the exchange, where it fills against the order book; ICE Clear Europe novates it; the clearing broker collects initial margin into segregated funds and passes variation margin between the client and the CCP every day. The fund rolls each quarter or closes when it no longer needs the hedge; a contract held to expiry settles in cash to the opening index level.
United Kingdom: the FTSE 100 and FTSE 250 futures trade on ICE Futures Europe and clear at ICE Clear Europe; the bank’s dealer is the clearing member for its clients; US index futures go through the bank’s US FCM.
FTSE 100 futures trade about GBP 10 billion a day on ICE Futures Europe, from 01:00 to 21:00 London time; the FTSE 250 futures and the Euro Stoxx 50 and DAX futures on Eurex follow the same model.
Fair value: futures trade at the index plus financing cost less expected dividends to expiry; the basis is arbitraged by program-trading desks buying the stock basket against selling futures, which keeps the two markets locked.
Margin: exchange minimums are set by ICE Clear Europe’s margin model, about 6% of notional for the FTSE 100 contract; the clearing member may charge more. Client margin is segregated under UK EMIR’s account models and the CASS rules or a title transfer arrangement.
Futures versus swaps: a fund that wants longer-dated or customized exposure uses an equity total return swap (see Equity TRS); futures are cheaper and cleared but roll every quarter and track only the major indices.
Where listed options stop (long dates, baskets, custom strikes and payoffs) the derivatives desk writes options bilaterally under the ISDA. The lifecycle follows the FX option with equity specifics: a stock delta hedge that settles at CREST, dividends and corporate actions to manage, correlation risk on a basket, UK EMIR reporting, and variation margin for two years.
Worked example, illustrative:client buys 2-year basket call, 10 US stocks, ATM, GBP 50m notionalbasket vol 22%, correlation 45%premium 14.2%, GBP 7.1mmargin 0.8 vol, about GBP 200,000delta 59%: buy about GBP 16m of stocksvaluation basket at 128%: pays GBP 14m

The desk prices the basket from each stock’s vol surface and a correlation assumption, charges a margin for the risks it cannot hedge, and buys the delta in stocks through the program desk. For two years it re-hedges daily and posts variation margin to the client. On the valuation date the calculation agent fixes the payout from the official closes and the bank pays cash two days later.
Regulation: options on single stocks and baskets are OTC derivatives under UK EMIR (reported to a trade repository by both sides, the margin rules for uncleared derivatives, the CRR capital rules).
Risks beyond vanilla: correlation (the buyer of a basket call benefits from high correlation, so the dealer who sold it is short correlation and cannot hedge it directly), dividends over two years, and stock borrow for any short delta.
Corporate actions: the ISDA equity definitions and the calculation agent handle mergers, spin-offs, special dividends and delistings in the basket by adjusting strikes, weights or replacing the stock.
Users: insurers hedging indexed annuities and structured note issuers are the natural buyers of long-dated options; hedge funds trade dispersion (index vol against single-stock vol) with the same desk.
A variance swap is a direct position on realized volatility: at maturity the parties exchange the difference between the realized variance of daily returns and a strike agreed today. The bank replicates it with a strip of listed options and daily futures hedges. The lifecycle has no premium and no coupons, only variation margin and a single payment at the end computed from a year of closing prices.
Worked example, illustrative:client sells variance FTSE 100, 1 year, vega notional GBP 500,000implied vol 18.0; fair variance strike 19.5client strike 19.0margin 0.5 vol, about GBP 250,000variance notional GBP 13,158 per variance pointcap 2.5× strikerealized 16.0: bank pays GBP 1,381,590

The fair strike comes from the price of the whole option strip, not one option. The client sells it a little below fair; the bank buys the strip and hedges delta every day, so its P&L is the difference between the variance it paid for and the variance the market delivers, plus the margin. Variation margin runs daily. At the end, 252 squared returns are summed and one payment settles everything.
Payoff = variance notional × (realized variance − strike²), with realized variance = 252/N × Σ ln(S_t/S_t−1)², annualized; vega notional = variance notional × 2 × strike so that one vol point near the strike is worth the vega notional.
The variance risk premium: implied variance has exceeded realized most of the time (investors pay for crash protection), so funds sell variance; the cap limits their loss in a crash like March 2020 when realized FTSE 100 vol exceeded 80.
Replication: a log contract is a strip of options weighted by 1/K², so the fair strike is model-free and the dealer’s hedge is listed options plus futures. ICE Futures Europe’s the FTSE 100 volatility index (VFTSE) is the 30-day version of the same formula; the FTSE 100 volatility index (VFTSE) futures and options trade the same risk in listed form.
Variants: volatility swaps (payoff linear in vol, harder to hedge), corridor and conditional variance, dispersion (index variance against single-stock variances) and the vol-of-vol trades in the FTSE 100 volatility index (VFTSE) derivatives.
Equity Total Return Swap, Synthetic Prime Brokerage
A total return swap gives the return of stocks without ownership of the stocks: the client receives price and dividends on a notional and pays a financing rate; the bank buys the shares as its hedge. It is the core of synthetic prime brokerage and the way hedge funds get leverage, short exposure and access to markets. The lifecycle is monthly resets, daily margin and a termination priced at the hedge’s unwind.
Worked example, illustrative:client receives total return on GBP 100m mid-cap basketclient pays SONIA + 60 bp, monthly resetinitial margin 20%, GBP 20mbank margin about 15 bp in the spreadhedge the bank buys GBP 100m of sharesVM daily; 5% move = GBP 5mterm 1 year, early termination at will

The prime brokerage desk sets margin and financing terms, the bank buys the shares and books the swap against them. Every day the swap is marked and cash margin moves; every month the return and the financing leg are exchanged and the notional resets. Dividends on the hedge pay the dividend leg. When the fund unwinds, the bank sells the shares and the sale price is the swap’s final price.
United Kingdom: the bank’s prime brokerage writes the total return swaps and the CFDs on UK and US names, reported under UK EMIR by both sides; the hedge is on the venues and settles at CREST (the intermediary relief spares the hedge the stamp duty); the UK short selling rules and DTR 5 count the synthetic positions.
Why swaps instead of shares: leverage beyond the prime’s margin (margin set by the bank’s risk model), short exposure without borrowing the stock directly, access to markets where the fund has no account, and no disclosure as beneficial owner (DTR 5 now aggregates the swaps into the DTR 5 notifications).
The bank’s economics: the financing spread over SONIA less its own funding, capital (leverage ratio consumption of GBP 100 million of shares on balance sheet) and the stock-lending income on the hedge shares.
Archegos (2021) was a family office with GBP 100 billion of such swaps across several banks; since then, prime brokers share concentration data, margin dynamically and every such swap is now reported to the trade repository under Reg SBSR.
Regulation: TRS on single names and narrow baskets are FCA derivatives reported under UK EMIR; on broad indices they are UK EMIR derivatives like any other. Dividend equivalents on UK shares attract the national withholding and anti-arbitrage rules, which the cum-ex and cum-cum cases made strict.
Equities›Share Plan Hedging
Hedging Share Plans: the Employee Benefit Trust and the Share Swap
A FTSE company satisfies its LTIP and SAYE awards with shares bought in the market by an employee benefit trust it funds, rather than new shares, so the cost of its share plans is the price of its own stock at the time the trust buys. The trust buys through a broker over the open periods and settles in CREST with stamp duty; or the company fixes the cost now with a cash-settled share swap from the bank, reported under UK EMIR, whose gain funds the trust’s later purchases.
Worked example, illustrative:company a FTSE company; LTIP over 4,000,000 shares, SAYE over 2,000,000, illustrativetrust an EBT funded by a GBP 30,000,000 loan, consolidated, own shares in equityroute M the trust buys on SETS over the open periods; CREST T+2; 0.5% SDRTroute S a 3-year cash-settled share swap on 2,000,000 shares, SONIA + spreadrules the financial assistance exemption; the IA dilution limits; UK EMIRaccounting IFRS 2 equity-settled; the swap at FVTPL

The trust turns the plans into a buying program the company funds but does not run: the trustee buys when the company is open and holds the shares until the awards vest. The swap is the way to buy the price today and the shares later.
United Kingdom: the UK version is the employee benefit trust buying shares in the market for the LTIP and SAYE awards, with a cash-settled share swap as the way to fix the cost now; the swap is reported under UK EMIR by the bank and the trust’s purchases settle in CREST with stamp duty.
The trust: an employee benefit trust (often offshore, in Jersey or Guernsey) holds shares for the plans at arm’s length from the company; the company lends or gifts the money, the Companies Act’s exemption for the purposes of an employees’ share scheme covers the assistance, and the trust is consolidated, so its shares show as own shares deducted from equity and its purchases are not a buyback needing a shareholder authority.
New shares or market shares: new shares cost dilution within the Investment Association limits (10% in ten years for all plans, 5% for the discretionary ones) and no cash; market shares cost cash and no dilution; treasury shares held by the company can also be used and count toward the limits. The choice is the remuneration committee’s and the treasurer’s.
The swap: a cash-settled equity swap fixes the cost of future purchases without tying up cash now; the company is a non-financial counterparty below the UK EMIR clearing thresholds, the bank reports for it, and the swap is a derivative at fair value through profit or loss; a physically settled forward between the bank and the trust delivers the shares at a fixed price instead.
Market abuse: the trust buys in the open periods and under instructions given while the company holds no inside information; the trustee’s independence is the protection, and the broker applies its own controls under MAR; the directors’ holdings and dealings follow the PDMR notification rules, the trust’s holdings the major shareholding rules where they apply.
ETFs trade like stocks but are born and die through authorized participants: a bank that delivers a basket of the underlying stocks to the fund and receives new ETF shares in return, or the reverse. The arbitrage between the ETF price and the basket keeps the ETF at its NAV; the creation and redemption flow through the CCP and CREST on T+2 alongside ordinary stock settlement.
Worked example, illustrative:client buys 2,000,000 ETF shares, GBP 200m, at the closeETF vs iNAV 100.02 vs 100.00client 100.015margin about GBP 10,000creation 40 units of 50,000 sharescreation fee about GBP 500 per ordersettlement T+2: basket in, ETF shares out, ETF shares to client

The client buys ETF shares from the bank; instead of buying them in the market the bank buys the underlying basket and hands it to the fund for new shares. On T+2 three things settle at once: the basket into the fund, the new ETF shares to the bank, and the ETF shares to the client against payment. Day to day the desk makes markets in the ETF and arbitrages it against the basket; redemptions run the loop backwards.
United Kingdom: the bank’s dealer is an authorised participant for the Irish UCITS ETF issuers, creating and redeeming at the transfer agent and settling through the ICSD structure or CREST depositary interests; the ETF trades on the London Stock Exchange and the MTFs and mostly OTC through the market makers on the RFQ platforms, reported through APAs.
US ETFs hold about GBP 10 trillion; creations and redemptions are in-kind for equity ETFs (securities for shares), and this is the source of their tax efficiency: the fund hands out low-basis stock in redemptions instead of selling it.
Authorized participants are investment firms with an agreement with the fund’s distributor; a few dozen banks and market makers do most creations. Fixed-income ETFs often create with cash or negotiated baskets because the bonds are hard to source.
the CCP processes ETF creations and redemptions through its ETF module so the basket legs net at the CCP; CREST credits the new shares to the AP. Standard settlement is T+2 like stocks; some international ETFs settle later.
The arbitrage keeps premiums and discounts to a few cents for liquid ETFs; in stress (March 2020) bond ETFs traded at discounts of several percent because the basket could not be sold at the marks the NAV used.
A convertible is a bond with an embedded call option on the issuer’s stock, traded by the equity-linked desk against a short position in the shares. The bond settles at CREST like a corporate; the hedge settles through the CCP like a stock; the client borrows the shares it shorts from the bank’s prime brokerage. The lifecycle ends in conversion into shares when the stock is above the conversion price, or in redemption at par when it is not.
Worked example, illustrative:client buys GBP 20,000,000 5-year 1.50% convertible, conversion price 50.00stock 42.00; delta 62%; vol 34%dealer run 101.50 / 102.25client 102.00 vs 42.00margin quarter point, about GBP 50,000hedge fund shorts 249,000 shares; desk buys back 249,000settlement T+2 DVP at CREST, GBP 20.4m plus accruedyear 5 stock 60.00: converted into 400,000 shares

The desk quotes the bond against the stock price, so both parties know the delta they are trading. The fund buys the bond and shorts the delta in shares through the bank’s stock loan desk; the desk, which was short shares against its inventory, buys that delta back. From then on both sides trade the gamma: as the stock moves they adjust the hedge, and the credit spread sets the floor. At year five the stock is above the conversion price and the bonds become shares.
United Kingdom: sterling and European convertibles are Eurobonds settled at the ICSDs and traded OTC with the banks’ convertible desks; the delta hedge runs on the venues with the locate under the UK short selling rules.
Pricing: a convertible is a straight bond (the investment value, from the issuer’s credit spread) plus a call on the stock (from implied volatility and borrow cost) with features layered on top: issuer call, holder put, dividend protection, takeover make-whole. Desks quote it as a dollar price versus a stock reference so that the delta is explicit.
Convertible arbitrage funds hold most of the paper: long the bond, short the delta in shares, earning the coupon, the short rebate and the gamma; they need borrow, so the bank’s prime brokerage and stock loan desks sit next to the trading desk.
Issuance: most US converts are 144A deals marketed overnight by the equity capital markets desk, with the bank buying back stock for investors’ hedges at pricing (the "delta placement"); the issuer often buys a call spread from the bank to raise the effective conversion price.
Settlement and reporting: CREST on T+2, the APA for the bond, the APA for the shares; conversion goes through CREST’s conversion agent service, with net share settlement increasingly standard so the issuer pays par in cash and only the excess in shares.
Autocallable Note on the FTSE 100, the Bank as Issuer
A structured note is the bank’s own debt with an option inside, sold to individuals through distributors. gilt raises three-year funding, the derivatives desk sells the index exposure, and the two are stapled into one senior note issued under the bank’s shelf, settled at CREST. The lifecycle is a series of observations: a coupon if the index holds above a barrier, early redemption if it is above its starting level, and a loss only if it ends below the barrier at maturity.
Worked example, illustrative:note GBP 25,000,000, 3 years, on the FTSE 100coupon 8.10% a year if the index is at or above 70%autocall at or above 100% from observation 2barrier 70% at maturityestimated value about 96.20: fee 2.50%, margin 1.30%funding SONIA + 70 bp to treasurypath obs 1 at 97%: coupon; obs 2 at 103%: called, GBP 25.51m paid

The distributor asks for a payoff, the desk prices the options and treasury the funding, and the gap between the issue price and the note’s estimated value is the fee and the margin. At closing the notes are born at CREST and the proceeds fund the bank. Every quarter the index is observed: in this example it pays a coupon at three months and is called at six, returning par plus coupon through CREST. The desk hedges the option package in listed FTSE 100 options and futures throughout.
United Kingdom: the banks issue autocallables and capital-protected notes under their base prospectus with a KID under the PRIIPs rules (the consumer composite investments regime replaces it), distributed through the structured product providers, the advisers and the private banks under product governance and the appropriateness or suitability tests, with the structured deposits inside the FSCS; the plans are not exchange quoted, the issuer makes the secondary market.
The US market issues about GBP 100 billion of structured notes a year, mostly autocallables and buffered or barrier notes on equity indices, sold through investment firms and private banks; the issuer’s credit matters, as noteholders of a failed issuer learned in 2008.
Disclosure: FCA-registered under the bank’s shelf, with a free writing prospectus during marketing and a final terms at pricing; since 2012 the issuer must disclose its estimated value of the note, which shows the fee and the margin as the gap to the issue price.
Inside the bank the note is two trades: a medium-term note issued by treasury at its internal funding rate, and an option package sold by the derivatives desk to treasury; rates-linked notes (callable range accruals), credit-linked notes and commodity-linked notes follow the same chain with other desks.
Risks the desk manages: the digital around the autocall level and the barrier, vega and dividends out to three years, and the correlation between the bank’s own funding and the index; secondary liquidity is provided by the issuer, bidding near the estimated value.
Equities›IPO
Initial Public Offering, the Bank as Lead Bookrunner
An initial public offering is how a stock comes into existence. The bank takes the company through the prospectus and the listing process, markets the deal on a roadshow, builds a book of orders, prices and allocates in one evening, commits to buy the shares and delivers them to investors at closing two days later. Then it opens the stock on the exchange, stabilizes it if needed, and exercises the greenshoe. It is the equity counterpart of the bond new issue, with the exchange involved from the first day.

Months of preparation, two weeks of marketing, one evening of pricing and allocation, one morning of opening, two days to closing. The fee is the gross spread; the risk is the underwriting commitment between pricing and closing and the stabilization short, which the greenshoe turns into an option.
United Kingdom: the IPO is a bookbuilt offering under a prospectus approved by the FCA (the POATRs), listed on the London Stock Exchange’s Main Market under the 2024 Listing Rules or admitted to AIM with a nominated adviser, with the stabilisation under UK MAR’s safe harbour and the FCA’s allocation rules; the closing through CREST on T+2; the listing reforms and the PISCES private market answer the thin IPO years since 2022.
Roles: the lead-left bookrunner runs the book and the process; joint bookrunners share the economics; co-managers add distribution. The gross spread (2% to 3.5% in London, with an incentive fee at the issuer’s discretion) splits into management fee, underwriting fee and selling concession.
Regulation: a prospectus approved by the FCA under the UK prospectus rules (the POATRs since January 2026), the quiet period, the FCA’s allocation rules (no spinning, a written allocation policy), UK MAR’s stabilisation safe harbour; the FCA’s 2018 IPO rules put the registration document and the unconnected analysts’ access ahead of the connected research.
The greenshoe: the banks sell 15% more shares than the base deal, creating a short they cover either by buying in the market (supporting a falling stock) or by exercising the option with the issuer (a rising stock). Stabilization is the one permitted form of price support.
Alternatives: direct listings (rare in London), the SPACs of 2021, PISCES for private company share trading, and follow-on offerings (marketed or overnight blocks) for companies already listed; the bank’s equities desk inherits the stock as a market maker in every case.
Equities›Accelerated Bookbuild
Accelerated Bookbuild and Block Trade
Follow-ons and blocks are the two ways of selling a large amount of an already listed stock. A marketed follow-on (M) is a smaller IPO: the company raises primary equity over two days of marketing, priced at a discount to the last close, settled T+2 with new shares issued into CREST. A block trade (B) is the opposite in speed and risk: a holder sells to the bank at a discount after the close, the bank re-offers the shares to wall-crossed investors overnight and settles T+2, keeping any unsold stock on its own book.
Worked example, illustrative:M, issuer GBP 600m primary, 15 million sharesM, pricing 4% discount, GBP 40; spread 3.5%M, client GBP 50m order, GBP 30m allocatedM, settlement T+2, new shares into CRESTB, seller 10 million shares, GBP 450m at the closeB, bank’s bid GBP 43.20, a 4% discountB, re-offer GBP 43.50 to 43.80 overnight; GBP 20m unsoldB, settlement T+2

Two routes from the seller to the investors. The follow-on is agency-like: the bank builds a book over two days and underwrites at the end. The block is principal: the bank owns the shares at 16:30 and has until the open to sell them, so it bids at a discount and calls wall-crossed investors in the evening. Both end at CREST, one with new shares, the other with existing ones.
United Kingdom: the follow-on is an accelerated bookbuild: an overnight placing with institutions under the prospectus exemptions of the POATRs (qualified investors, fewer than 150 persons, admissions below 75% of the existing shares), within the Pre-Emption Group’s 20% guidelines (10% plus 10% for an acquisition, with a retail offer alongside), often a block from a selling shareholder bought by the banks on risk; the rights issue is the alternative for a large capital raise.
Follow-ons: marketed (two to three days, the standard for large primary raises), accelerated bookbuilds (one evening, for sellers who can accept a wider discount) and the rights issues and open offers for the large raises under the pre-emption rights; the 2026 prospectus rules exempt most placings from a prospectus.
Blocks: a competitive auction among a few banks after the close; the winner buys as principal and bears the overnight risk; wall-crossing lets the bank sound out investors before the launch under confidentiality; UK MAR’s market sounding rules make the information handling around the bid a compliance focus.
UK MAR’s stabilisation safe harbour and the buy-back and stabilisation rules restrict the underwriters’ trading in the stock around an offering; UK MAR and the wall-crossing agreements govern what investors may do with the knowledge of a pending block; the bank’s equities desk, ECM and compliance all sit in the room for the bid.
Settlement: a placing settles T+2 after the admission of the new shares; a block of existing shares is a secondary trade and settles T+2 through the CCP like any sale from the bank’s account.
A producer locks in a price for next year’s production: it receives a fixed price and pays the monthly average of the NYMEX WTI front-month settlement. The bank hedges in WTI futures at CME and carries the credit exposure to the producer uncollateralized. Each month one cash settlement passes between them.
Worked example, illustrative:client receives fixed USD 72.20 per barrel, 500,000 bbl a month, 12 monthsfutures strip avg USD 72.40margin 20 cents, USD 100,000 a monthhedge sell 500 WTI futures per month, 6,000 totalmonth 1 WTI avg 68.50: bank pays USD 1.85mVM on hedge USD 1 = USD 6m

The desk prices the strip off the futures curve and bids below mid; once dealt, it sells the equivalent futures at CME and is left with the credit risk on the producer and the basis between a monthly average and daily settlements. The hedge pays and collects margin daily; the swap pays once a month; the gap is funded by treasury. After twelve settlements the strip is done.
Commodity swaps are FCA swaps; producers and consumers hedging commercial risk may elect the end-user exception from clearing, so many stay bilateral and uncollateralized within a credit line (often secured on reserves alongside the reserve-based loan).
The dealer’s hedge is listed futures (WTI at NYMEX, Brent at ICE) or cleared swaps at CME ClearPort; the mismatch between a monthly-average swap and a single futures settlement is the Asian-option basis the desk manages by selling the hedge down through the month.
Position limits: the FCA and the exchanges set limits on futures and economically equivalent swaps in energy; bona fide hedge exemptions cover the dealer’s hedges of client swaps.
Variants: collars and three-way collars (options), swaps on basis (WTI Midland vs Cushing, natural gas at Henry Hub vs regional hubs), and physical supply contracts for utilities and refiners.
Producer Hedge Program in the UK: Brent Collars and Swaps Under a London RBL and the Energy Profits Levy
A North Sea producer hedges its Brent under its London reserve-based loan: the RBL banks quote collars on the ICE Brent average and swaps on Dated Brent, the hedges are secured with the debt so no margin moves, the producer stays outside the clearing obligation as an NFC- under UK EMIR while the bank reports for both, and the Energy Profits Levy sets how much of each dollar of price the producer keeps.
Worked example, illustrative:program 40% to 60% of the next 18 months under the London RBLcollar 250,000 barrels a month: 64 put bought, 86 call sold on the ICE Brent averageswap 100,000 barrels a month of Dated Brent at USD 73.40UK EMIR NFC- below the EUR 3,000,000,000 commodity threshold; the bank reports for bothtax the Energy Profits Levy at 38% on the ring fence profits to March 2030accounting IFRS 9 cash flow hedges for many producers

The North Sea producer sells physical cargoes priced on Dated Brent and hedges on the ICE futures average and on Dated itself; its lenders require the hedges and hold them as secured debt. The levy changes the economics, not the mechanics: more of the price goes to the Treasury, less is left to protect.
United Kingdom: a North Sea producer hedges Brent and Dated Brent with the banks of its London RBL, outside the clearing obligation as an NFC- under UK EMIR, and pays the Energy Profits Levy on the profits it hedges.
The London RBL: an LMA-based facility with a banking base set from the net present value of the fields at the banks’ price deck, redetermined twice a year by the technical bank and the agent, with the hedging requirement, the hedge counterparties limited to the lenders, and the hedges ranking with the debt under the intercreditor agreement; the decommissioning security for the fields sits beside it.
Brent and Dated Brent: ICE Brent futures settle in cash against the ICE Brent index; the physical North Sea cargoes are priced on Dated Brent, the Platts assessment of the loading cargoes (with WTI Midland in the basket since 2023); a producer hedging its sales uses Dated Brent swaps or the futures with a CFD to bridge the two.
The Energy Profits Levy: introduced in May 2022, raised to 38% from November 2024 on top of the 30% ring fence corporation tax and the 10% supplementary charge, to end on March 31, 2030 under the Finance Act 2025, with a revenue-based price mechanism at USD 90 a barrel and 90p a therm announced to follow; a hedged producer pays the levy on its profits and keeps less of each price move.
UK EMIR: a non-financial counterparty below the clearing thresholds (EUR 3,000,000,000 gross notional for commodity derivatives, the hedging trades excluded) is an NFC-: no clearing, no margin with its dealers, and the financial counterparty reports its trades for it; above them the producer would clear and margin its non-hedging trades.
Listed oil and products futures at NYMEX (CME) and ICE, used by producers, consumers and funds. The bank is the clearing member: it routes, clears and margins the client’s positions, and is responsible to the clearing house for them, including the physical delivery obligations the client must avoid by closing before expiry.

The clearing broker lifecycle of financial futures with two differences: margins are larger and move with energy volatility, and the ending is physical. A long that holds through the last trading day takes delivery of product at the exchange’s delivery point, so the clearing broker makes sure clients close or roll before then.
The main contracts: WTI crude (NYMEX, physical at Cushing, Oklahoma), Brent (ICE, cash settled), RBOB gasoline and ULSD (NYMEX, physical at New York Harbor), Henry Hub natural gas (NYMEX, physical), power at ICE and Nodal.
Physical delivery makes energy futures different from index futures: the clearing broker is liable to the clearing house for delivery, so it monitors clients’ open positions into the delivery period and liquidates those who cannot perform.
Negative WTI in April 2020: the May contract settled at −USD 37.63 because longs could not take delivery with Cushing storage full; clearing brokers absorbed losses from clients who could not pay, and margin models were changed to allow negative prices.
Position limits apply to the spot month and all months combined; bona fide hedgers (an airline hedging fuel) file for exemptions. The FCA and exchanges share large-trader data daily.
Gold trades like a currency, priced in USD per troy ounce and settled T+2 loco London, with COMEX futures as the hedging market. The lifecycle forks at settlement: unallocated metal is a book entry, a claim on the bank for ounces, cleared between bullion banks through AURUM (U); physical means identified good-delivery bars in a vault or COMEX warehouse warrants, with premiums, logistics and storage (P).
Worked example, illustrative:client buys 10,000 oz gold spot, loco Londonmarket 2,650.00 / 2,650.50client 2,651.00margin 50 cents, USD 5,000EFP +8 futures over spotU settlement USD 26.51m against unallocated creditP settlement plus USD 1.50/oz premium: 25 bars allocated

The desk prices off COMEX and the London spot market and hedges in futures plus the EFP. On U the client pays dollars and receives a credit in ounces on its unallocated account, and the bank’s own hedge settles between bullion banks by book entry through AURUM. On P the client pays a premium and receives a list of specific bars allocated to it in a vault; the bank may source them by standing for delivery of its futures.
Loco London: the standard for OTC gold is delivery in London, unallocated, T+2; the London clearers settle among themselves through LPMCL’s AURUM system, transferring metal by book entry against USD. The LBMA sets good-delivery standards (350 to 430 oz bars, 995 fineness minimum) and runs the twice-daily gold price auction (ICE Benchmark Administration).
Unallocated versus allocated: unallocated is an unsecured claim on the bank (cheap, fungible, lendable; the bank can lease the ounces); allocated is specific bars held in custody (storage fees, no credit risk on the bank). Basel III’s NSFR treats unallocated gold as a funded asset, which pushed banks to shrink those books.
COMEX (CME) gold futures are the price-discovery and hedging market; the EFP links futures to London spot. Standing for delivery yields warrants on 100 oz or kilo bars in New York depositories; the 2020 and 2025 dislocations in the EFP showed how shipping between London and New York can bottleneck.
Regulation: spot and physically settled forwards on gold are not swaps; gold is treated as a currency for capital purposes in some rules; LBMA’s Global Precious Metals Code governs conduct. Silver, platinum and palladium follow the same lifecycle with their own clearing and delivery specifics.
Industrial metals trade on the London Metal Exchange as forwards for any daily prompt date up to three months and monthly beyond, cleared at LME Clear, with physical delivery by warrant in an approved warehouse. The bank is a member: it faces the client as counterparty, covers on the screen or at the ring, and clears both sides. Most positions close out in cash; the ones that go to the prompt date end in warrants.
Worked example, illustrative:client buys 5,000 t copper, 200 lots, 3-month promptLME 3-month USD 9,250 / 9,254client USD 9,258 per tonne, USD 46.29mmargin USD 4 per tonne, USD 20,000USD 100 move USD 500,000 of variation marginprompt 1,000 t delivered by warrant, 4,000 t closed out in cash

An LME contract is a forward with a daily prompt date, not a quarterly future: the quote, the cover and the clearing are LME-specific, the margin cycle is a clearing house’s, and the ending is either a cash close-out or a warrant for metal in a warehouse. The LME’s curve of prompt dates and its warehouse stocks are what the desk trades.
The LME trades copper, aluminum, zinc, nickel, lead, tin and others in lots of 25 tonnes (6 for nickel and tin), for daily prompts to three months, weekly to six, monthly to ten years; the ring (open outcry) sets the official and closing prices used in physical contracts worldwide; CME’s COMEX copper and the Shanghai Futures Exchange are the alternatives.
Members: category 1 (ring dealing) and category 2 members clear at LME Clear and face clients as principals; the client contract and the market cover are both LME contracts, so the bank is a counterparty, unlike a clearing broker on CME.
Margin: LME Clear uses contingent variation margin on forwards (settled at the prompt, collateralized until then) rather than the daily cash settlement of a future; the March 2022 nickel episode (an 8-hour short squeeze to USD 100,000, trades cancelled) rewrote the margin and position-limit rules.
Delivery: a warrant is a document of title to a lot in a named LME warehouse; warrants are transferred on LMEsword, cancelled to take the metal out, and the queues and rents at warehouses are themselves a market; producers, consumers, traders and financiers use the LME to hedge physical business priced off its official prices.
Grains and softs trade as CBOT, ICE and KC futures with the bank as clearing member: a producer or consumer hedges the price of a physical crop, the basis between the futures and its local cash price is what remains, and the contract delivers by shipping certificate if held into the delivery month. Federal position limits, hedge margin rates and USDA reports shape the lifecycle.
Worked example, illustrative:client buys 500 December corn, 2.5 million bushelsprice USD 4.50 per bushel, USD 11.25mIM about USD 1,500 per contract, USD 750,000 (hedge rate)1 cent USD 50 per contract, USD 25,000position limits federal spot-month and all-months limitsdelivery shipping certificate at an approved elevator

The clearing broker lifecycle of any listed future, with agricultural specifics: hedge margin rates for commercial hedgers, daily price limits, the spot-month position limit, and a delivery by shipping certificate instead of a wire or a pipeline. The producer closes the hedge when it buys the physical, so delivery is the exception.
The contracts: corn, soybeans, wheat (CBOT and KC), soybean oil and meal, oats, rough rice; sugar, coffee, cocoa and cotton on ICE; live cattle and hogs on CME; all with the bank as clearing broker and some with the bank’s own commodities desk writing OTC swaps for clients that want cash settlement.
Hedgers and speculators: commercial hedgers (producers, elevators, processors, exporters) get hedge margin rates and hedge exemptions from position limits on proof of the physical business; the FCA’s Commitments of Traders report shows the two sides every week; the FCA’s position limits apply to the critical commodity contracts (Brent, gasoil, the agricultural contracts on ICE Futures Europe), set by the FCA for the venue.
Delivery: CBOT grains deliver by shipping certificate or warehouse receipt at approved elevators along the Illinois River and at the Gulf; the oldest long is assigned first; most hedgers close out against the physical instead, keeping the basis (cash price minus futures) they negotiated with their elevator.
The market moves on USDA reports (the monthly WASDE, acreage and stocks reports), weather and export sales, and has daily price limits that expand after limit moves; the bank’s commodities desk hedges its OTC swaps in the same futures.
UK Allowances for a Gas-Fired Generator: the ICE Auctions, the Futures Hedge and the UK ETS Registry
A gas-fired generator fixes its clean spark spread: it sells power forward, buys the gas and buys the allowances, part at the fortnightly UK ETS auctions on ICE Futures Europe and part forward from the bank, which hedges in the UKA futures. The allowances move in the UK ETS Registry, the futures deliver through ICE Clear Europe, the payment goes by CHAPS, and the generator surrenders by April 30; the forward is a derivative under UK EMIR because the allowances are financial instruments.
Worked example, illustrative:client a gas-fired generator, 3,000,000 t a year, no free allocationtrade 2,000,000 UKAs for December at GBP 45.50, illustrativehedge 2,000 December UKA futures on ICE, cleared at ICE Clear Europeauctions every two weeks on ICE Futures Europe, about 52,000,000 UKAs in 2026compliance verified report by March 31, surrender by April 30classification UKAs are financial instruments: UK MiFID, UK EMIR reporting, UK MAR

In the UK the allowances are financial instruments, so the bank’s forward is a reportable derivative and the market is the FCA’s. The generator buys its carbon as one leg of its spark spread, at the auctions and from the bank, and the link with the EU ETS under negotiation would make UKAs and EUAs one market.
United Kingdom: the UK ETS has its own allowances, auctions and registry since 2021; the allowances are financial instruments, so the forwards are UK EMIR derivatives, and a link with the EU ETS is under negotiation.
The UK ETS replaced the EU ETS in the UK from 2021: the cap set by the four governments’ UK ETS Authority, the free allocation to the industry exposed to carbon leakage (none for power), the auctions run by ICE Futures Europe every two weeks, a market stability mechanism, and a registry run by the Environment Agency.
Expansion: the domestic maritime emissions are in the scheme from July 1, 2026 for ships of 5,000 gross tonnage and above; waste incineration and energy from waste report from 2026 and are fully in from 2028; greenhouse gas removals are planned.
The EU link: at their May 2025 summit the UK and the EU agreed to work toward linking the two systems, which would make the allowances mutually recognized and exempt each side from the other’s CBAM; the talks continued through 2026 with an agreement targeted for a summit by the end of the year. The UK CBAM itself starts on January 1, 2027 for aluminium, cement, fertilisers, hydrogen, iron and steel.
Regulation: UKAs are financial instruments under UK MiFID, so a forward or an option on them is a derivative reported under UK EMIR and trading in them falls under UK MAR; the auctions themselves are regulated under the auctioning regulations and the FCA’s rules.
Inside the Bank›Front to Back
One Trade Through the Bank, Front to Back
The corporate bond trade of the Fixed Income section, seen from inside the bank: which team touches it, in what order, in which system. Sales and trading make the price and take the risk; the middle office checks, confirms and reports; operations settles and reconciles; finance turns it into P&L and a ledger entry. Most of it is straight-through processing; the people work the exceptions.
Who uses what:front office pricing engine, RFQ dealer screens, trade capture (Murex, Calypso, Summit, Bloomberg TOMS, Fidessa)middle office trade support queue, CTM, confirmation system, reporting huboperations settlement system (Broadridge or the back-office module of Murex or Calypso), SWIFT gateway, reconciliation tool (SmartStream TLM, Duco)finance P&L system, sub-ledger, general ledger (SAP, Oracle)backbone client master, security master, SSI database (DTCC ALERT), market data

The columns run left to right: the client, then the bank’s teams in the order a trade reaches them, then the market and its infrastructure. Every arrow is a data flow between two teams or two systems and the pill names the system. The chain is the same for every product; what changes is which trade capture system, which confirmation platform and which settlement rail.
United Kingdom: the bank is a PRA-authorised bank under the PRA’s rulebook (the onshored CRR and the Basel 3.1 rules), with its markets division authorised under COBS by the FCA and outside the ring-fenced retail bank; the trade runs through the same chain with the CCPs, CREST and CHAPS as the infrastructure and the FCA, the PRA and the Bank of England as the supervisors.
Who is who: the front office faces the client and takes the risk; the middle office (trade support) sits between the desk and operations and owns the exceptions, confirmations and regulatory reports; the back office (operations) makes the exchange of value happen; finance owns the official numbers. Risk and compliance sit alongside (see Risk, Finance, Compliance).
Systems: most banks run one trade capture system per asset-class family (a rates and FX system, a credit and equities system, a loans system), one settlement system, one ledger, and a layer of reference data (client master, security master, SSIs) that everything depends on. The "golden source" of a trade is the front-office booking; every other system is a copy that must reconcile to it.
STP and exceptions: on an electronic trade nothing above is typed by a human after the quote; the cost of operations is in the 1% to 5% of trades that break a check, a match or a settlement. T+2 settlement (May 2024) pushed allocation and matching into the evening of trade date, hence the end of T cut-off throughout.
Controls along the way: the pre-deal limit check, the price-tolerance check, the confirmation match, the matching, the settlement match at CREST, the nostro and depot reconciliations, and product control’s P&L explain are the seven points where an error is caught before it costs money.
Inside the Bank›Client Onboarding
Client Onboarding, KYC and Documentation
No trade happens until the client exists in the bank’s systems: identified and screened, documented under the right agreements, given credit lines and settlement instructions, and set up in every system that will see its trades. Onboarding runs the case across KYC, legal, credit and reference data; sales sponsors it; the client waits. It is the longest lead time in the business and the source of most first-trade failures.
Who uses what:onboarding onboarding and case system (Fenergo, Pega, Salesforce, in-house), client portalKYC and compliance screening tools (LexisNexis, Dow Jones, World-Check), KYC utilities (Markit, Swift Registry), transaction monitoringlegal and credit document negotiation and repository, the limits systemreference data client master (the golden record), DTCC ALERT for SSIs, entitlementssales CRM, the revenue case

A request, a case, the KYC file and its risk rating, the agreements and the lines, the settlement instructions, the setup of the golden record and the downstream systems, then the periodic review and the changes. Every product lifecycle begins with a client who is already set up; this view covers the setup.
United Kingdom: onboarding runs under the FCA’s client categorisation and information rules, the Money Laundering Regulations’ identification and beneficial ownership rules, UK EMIR’s counterparty classification (FC, NFC+, NFC-) and the LEI for reporting, the CASS acknowledgment letters and the ISDA and clearing documentation.
KYC is the law: the Money Laundering Regulations and the National Crime Agency customer due diligence rule (beneficial ownership, 2018) in the US, the AML directives in Europe; the bank must identify the client and its beneficial owners, screen them, rate the risk, monitor the activity and refresh the file; failures cost banks billions in fines, so onboarding is deliberately thorough.
The documents: the ISDA master and CSA for derivatives, the MRA for repo, the GMSLA for securities lending, the futures customer agreement and the cleared derivatives execution agreement for listed and cleared products, the prime brokerage agreement, the FX master (or the ISDA) for FX; each takes negotiation, and the terms (thresholds, haircuts, eligible collateral, events of default) drive the collateral and credit processes.
The golden record: one client master feeding every other system is the aim; most banks have several (one per legacy platform) with reconciliation between them, so onboarding is also a data problem; LEIs (legal entity identifiers) are the common key since 2012.
Timing: a simple fund trading listed products at a bank it already knows can be live in days; a new manager with dozens of funds, bilateral derivatives and repo takes two to four months; utilities, portals and shared KYC services (Markit, Swift, Kyckr) exist to cut the document chase.
Inside the Bank›Reference Data
Reference Data and the Security Master
Reference data is one record per instrument and per client that every system reads before it can book, price, settle, margin or report a trade. The reference data team sources instruments from the vendors when a trade needs them, validates and golden-copies the record, propagates it everywhere, and maintains it through thousands of daily changes and corporate actions. Data governance sets the owners, the rules and the regulatory standards.
Who uses what:reference data team security master and client master platforms (in-house, GoldenSource, Bloomberg, SIX, Fenergo for clients), validation rules, exceptions queuesources Bloomberg Data License, LSEG, ICE Data, ISIN Global Services, exchanges, GLEIF (LEIs), rating the agencies and supranationals, issuers’ prospectusesconsumers every trade capture, pricing, settlement, risk, ledger and reporting systemdata governance the chief data office: ownership, quality rules, lineage, BCBS 239, ISO and regulatory standards

A new instrument from request to distribution, the daily maintenance of changes and corporate actions, the quality loop fed by the problems the rest of the bank finds, and the governance on top. The security master appears as a system on most other desk views; this view covers what sits behind it.
United Kingdom: the security master carries the ISINs and SEDOLs with CREST and ICSD settlement details, the LEIs and the FCA’s instrument reference data (FIRDS), the venue identifiers (MICs) and the UK EMIR product classifications; the UK pricing sources sit alongside the global vendors.
Identifiers: ISIN (US and Canada, from ISIN Global Services), ISIN (international, built from the ISIN in the US), FIGI (Bloomberg’s open identifier), SEDOL (UK), ticker and exchange symbol, RIC (LSEG); the LEI identifies the legal entity (issuer or counterparty) and is mandatory in most regulatory reports; a security master cross-references all of them.
The record: identifiers, issuer, terms (coupon, maturity, day count, business-day convention, calendars, calls, puts, conversion, amortization, factors), classification (asset class, product type, CFI, sector, country, rating), listing and trading data (exchange, lot size, tick), settlement data (depository, cycle), accounting and regulatory flags; derivatives and structured products need templates instead of static records.
Consequences of errors: a wrong day count mis-prices every trade in the bond; a missing depository fails every settlement; a stale rating mis-states capital; a duplicate record splits a position in two; the regulators (BCBS 239, the FCA and FCA reporting rules) require the bank to show where every reported field comes from.
Client master versus security master: the same discipline applied to legal entities (see Client Onboarding): LEIs, hierarchies (the fund, its manager, its parent), agreements, SSIs, ratings, KYC status; both are the golden sources the rest of the bank must not override locally, and both are where most banks still carry legacy duplicates.
Inside the Bank›New Product and Models
New Product Approval and Model Governance
New product approval is how a product enters the bank’s catalog. A desk proposes it; a committee of every control and support function decides whether the bank can price it, book it, confirm it, settle it, margin it, account for it and report it, and under which rules; the quants build the model and model risk management validates it independently; operations and technology build what is missing; the product goes live with conditions and is reviewed. The model inventory and the product inventory are what the examiners ask for first.
Who uses what:business sponsor the proposal: product, clients, revenue, risks, systemsnew product committee the approval workflow and the product inventory (in-house, GRC platforms)quants the pricing library, the model documentationmodel risk management the model inventory, validation reports, monitoring and re-validation (the PRA’s model standards)operations and technology templates in trade capture and confirmation, the build plan, the dry runaudit and regulators the third line; the PRA’s model standards, the CRR trading book rules, the product perimeter

A proposal, the assessments by every function, the model built and validated in parallel, the build and the readiness check, the approval with conditions, then the monitoring and the review. The process is deliberately thorough: nothing trades that the bank cannot process and control, and no model prices a book without an independent check.
United Kingdom: new product approval runs under PROD (the target market, the manufacturer and distributor duties), the KID for retail products, the Consumer Duty and the PRA’s expectations for the bank; the model governance follows the PRA’s model risk principles and the SMCR accountability.
New product approval: every bank runs one (the NPA, NPC or NBI process); the definition of "new" is the first question (a new payoff, a new underlying, a new client type, a new booking entity, a new jurisdiction all count); the committee’s sign-offs are the evidence that risk, finance, legal, compliance, operations, technology and treasury each considered the product; regulators and auditors test the process, and products traded without it are findings.
Model risk: the PRA’s model standards (the Bank of England and ICE Clear Europe guidance, 2011) defines a model, requires an inventory, independent validation proportionate to materiality, ongoing monitoring and governance; it covers pricing models, risk models (VaR, CCR), valuation adjustments, and increasingly the machine-learning models in surveillance and pricing engines; the model inventory of a large bank runs to thousands of entries.
The three lines on models: the quants (first line) build, document and test; model risk management (second line) validates and monitors; internal audit (third line) tests both; the model owner is a named person accountable for the model’s use within its approved scope.
Why products fail here: a payoff the systems cannot book without a spreadsheet, a confirmation that needs a lawyer for every trade, a valuation that needs a manual process, a regulatory treatment nobody can settle (a swap or a security?), or a model whose limitations the desk will not accept; the committee’s conditions (caps, limits, reviews) are how a bank trades a new product while it learns.
Inside the Bank›Market Data and Pricing
Market Data, Curves and Pricing
Every quoted price starts with market data. Feeds from venues and vendors are normalized by the market data team, the quants turn them into curves and surfaces in the pricing library, the trader marks the instruments and sets the skew and the inventory, the pricing engine turns that into quotes and streams at scale, and at the close the same marks become the valuation that finance and risk check independently.

Top to bottom: the raw feeds, the curves built from them, the trader’s marks, the quotes those produce, the end-of-day valuation and the controls on the models and the data. The product sections show the quote arriving at the client; this view covers what happens before the pricing engine answers.
United Kingdom: the curves are built from SONIA and the gilt curve, with the swap spreads and the linker break-evens; the APAs, the gilt-edged market makers’ screens and the London Stock Exchange are the UK market data sources alongside the global vendors, with the bond consolidated tape to come.
The curve set is the bank’s view of the market: discount curves (SONIA, ESTR, SONIA), projection curves per index, gilt and agency curves, FX forward and cross-currency basis curves, vol surfaces (rates, FX, equity, commodity), credit curves per name and index, dividend and repo curves for equities, inflation curves; a large bank maintains thousands, rebuilt many times a day.
Marks versus independent prices: the trader marks the book and the pricing engine quotes off those marks, but the official valuation is finance’s; independent price verification compares the marks with external evidence and the difference, with the reserves, is a valuation adjustment. The more illiquid the instrument, the more the mark is a model and the larger the reserve.
The pricing engine is the industrialized trader: in FX, equities, gilts and increasingly credit it answers most RFQs and streams prices with no human in the loop, within parameters the trader sets (spreads by tier, skew by inventory, maximum size, last-look windows); the trader handles the exceptions and the large tickets.
Data is a business in itself: Bloomberg, LSEG and ICE sell the feeds; exchanges and interdealer brokers sell their own; the market data team manages hundreds of contracts, entitlements per user and application, and the audits that go with them. Benchmark fixings (SONIA, WM/Refinitiv, LBMA) are regulated since the SONIA and FX fixing scandals.
Inside the Bank›Hedging and Positions
Hedging and Position Management
After every client trade the trader has to deal with the risk: hedge it in the market, warehouse it inside the limit, or internalize it against the next client. The book is managed as net risk by factor, re-hedged as the market moves, funded by treasury and charged for the credit and capital it uses. Market risk watches it live and signs off at the close. In the liquid markets most of this is done by the auto-hedger.

Mandate and limits first, then the loop that runs all day: a client trade changes the net risk, the trader (or the engine) hedges, warehouses or internalizes, risk sees it live, the market moves and the book is re-hedged. At the close the day is explained by risk factor, and treasury and xVA send the bill for the balance sheet, funding and credit the positions consumed.
United Kingdom: the hedges run on ICE Futures Europe (the gilt complex, the FTSE 100 and FTSE 250 futures and options, the SONIA futures), at LCH SwapClear for the SONIA swaps, and on the global venues for the rest; the desk’s risk limits are under the PRA’s market risk rules and the bank’s own framework.
Hedge, warehouse, internalize: back-to-back hedging keeps only the sales margin and pays the market’s bid-offer; warehousing earns the bid-offer the bank quoted but takes the risk until the next client; internalization matches one client against another and earns both spreads. A market maker’s edge is the share of flow it can internalize.
Instruments: the hedge is rarely the same product as the trade. Rates desks hedge DV01 with gilt futures and interdealer swaps and vega with listed options and swaptions; FX desks hedge in spot and forwards on ECNs; credit desks hedge beta with iTraxx and rates with gilts; equity desks hedge delta in stock and futures and vega in listed options. The basis between hedge and position is the residual risk.
Greeks: delta (price), DV01 (rates), vega (volatility), gamma (how delta changes), theta (time), CS01 (credit spread), correlation, dividends, basis. The limits are set per Greek per book; the hedging policy says which must be flat by when; the P&L attribution explains the day by the same Greeks.
Automation: in FX spot, cash equities, gilts and listed derivatives the auto-hedger runs the loop (internalize, net, hedge above threshold) in milliseconds; the trader sets the rules and handles the exceptions and the large tickets; in exotics and illiquid credit the trader still does it by hand.
Confirmation is the agreement of the facts of every trade with the other side, the same day, by the route that fits the product: SWIFT messages matched field by field for FX and money markets (X), electronic matching on Markitwire, MarkitSERV or a signed document for OTC derivatives (D), allocation and matching through CTM for securities (S). The work is in the exceptions: economic breaks go back to the desk, operational breaks to the counterparty, and nothing settles cleanly until the trade is matched.

Three routes side by side after one shared capture step: the FX route matches two SWIFT messages, the derivatives route matches on a platform or signs a document, the securities route allocates and matches through CTM matched under the T+1 code’s allocation and confirmation practices. The exceptions and the controls at the bottom are shared. Every product passes through one of the three routes.
United Kingdom: confirmations run on the same platforms (MarkitWire, MarkitSERV, CTM, SWIFT) with the UK custodians and counterparties; UK EMIR’s confirmation deadlines and the T+1 code’s allocation and confirmation practices set the timing; the bond trades are confirmed dealer to dealer and published through the APA.
A confirmation is the legal record of the trade; an unconfirmed trade is a dispute waiting to happen (the 2005 credit derivatives backlog, when dealers had tens of thousands of unconfirmed trades, is what created Markitwire, MarkitSERV and the Trade Information Warehouse).
The routes: FX and money markets match SWIFT messages (MT300 for FX, MT320 for deposits, MT305 for options), increasingly through central matching; rates and credit derivatives affirm electronically, and the platform record is the confirmation; securities use allocation and matching through CTM, which since T+2 must be done matched under the T+1 code’s allocation and confirmation practices.
Economic versus operational breaks: a different rate or notional means the two parties think they did different trades, and the desk must resolve it today; a wrong SSI or a missing reference is fixed by operations. Aging reports and the UK EMIR confirmation deadlines (T+1 for cleared and electronically confirmed trades, T+2 otherwise) are the controls.
Straight-through: on an electronic trade the confirmation is generated and matched without a human; the team works the 2% to 10% of exceptions, with paper confirmations for structured trades the largest share of the effort by far.
Inside the Bank›Clearing and Custody
Clearing, Settlement and Custody
Clearing, settlement and custody are what happens to a trade after it is matched and before it is a position the bank can rely on: clearing (a CCP steps in, guarantees and nets the trade), settlement (securities and cash change hands at the depository) and custody (the bank holds its own and its clients’ securities in segregated accounts, reconciles them every day and services the income and corporate actions). Three teams, all in operations, around the infrastructures the products settle through.
Who uses what:clearing CCP portals and reports (LCH Ltd, the CCP, ICE Futures Europe, ICE Clear Europe, LCH, ICE), reconciliation of CCP records to the front-office tradessettlements settlement system, SWIFT gateway, CREST and CREST interfaces, fails managementcustody and asset servicing custody system, depot reconciliation (SmartStream TLM, Duco), corporate actions platform, custody and prime brokerage portalsfinance and risk segregation computation, CCP exposure reports, capitaldesks position system fed by settled positions, entitlements and elections

Time runs down from memberships through submission and netting, settlement, margin, custody and the daily controls. Clearing turns bilateral trades into net obligations against a guaranteed counterparty; settlement moves the net; custody keeps the record and services it. Cash management and collateral have their own views; this one covers the securities.
United Kingdom: the bank’s dealer is a clearing member at LCH Ltd, ICE Clear Europe and Cboe Clear Europe and a CREST participant with its own settlement bank status, settling the cash through CHAPS and the ICSDs for the Eurobonds; US securities settle through the bank’s US broker-dealer; the custody arm holds the clients’ assets under the CASS custody rules.
Clearing versus settlement: clearing is the step where a CCP becomes the counterparty and nets obligations (LCH Ltd and the CCP for securities, ICE Futures Europe, ICE Clear Europe, LCH and ICE for derivatives); settlement is the exchange of value at the depository (CREST, CREST) or through the CCP’s margin accounts. Some products are cleared and settled (gilts, stocks), some only settled (FX spot, uncleared derivatives), some only cleared (futures, swaps, which never settle a principal).
Cleared repo at LCH Ltd carries most of the gilt repo market, with the funds reaching it through clearing members or LCH’s sponsored clearing at LCH Ltd; dealers are building the sponsored and done-away models for their clients now.
Custody and segregation: an investment firm holds customer securities under FCA the CASS rules (client asset segregation, reserve formula), a clearing broker holds customer margin under FCA segregation rules; the daily computations and the depot reconciliation are what regulators examine first after a failure (MF Global, 2011).
Fails: a delivery not made on settlement date; most clear within a day, aged fails attract capital charges and, for gilts, the cost of the repo that covers the fail; securities lending exists largely to make deliveries that would otherwise fail (see Securities Lending).
Every derivative, repo and forward reaches collateral management the next morning. The risk engine values the book overnight, collateral management turns the moves into margin calls out and in (bilateral under the CSAs, and the CCPs’ calls on the bank), treasury decides what to post and funds it, settlements moves the cash and securities, and credit risk watches what is not covered. One day in the cycle, with one call out and one call in.

Time runs down through one margin day: end-of-day valuation, calls by the morning deadline, agreement or dispute, funding, delivery, reconciliation. The CCP call arrives at night and must be paid by 09:00 London time; the bilateral calls go out by 10:00 London time and settle the same day. gilt sits in the middle because margin is a funding problem as much as an operational one.
United Kingdom: the bank exchanges margin under the UK EMIR margin rules for its uncleared derivatives, posts margin at LCH Ltd and ICE Clear Europe, and runs its collateral through the triparty agents (Euroclear Bank, BNY, J.P. Morgan) and CREST; UK SFTR’s reuse rules and the exchanges’ and the CCPs’ buy-in rules (no cash penalties on fails in the UK) apply.
Scale: a large dealer runs thousands of CSAs and several hundred calls a day, most agreed without a word; disputes are a small share by count but carry the risk, so the regulators require them to be reported when large or old.
Bilateral versus cleared: under a CSA the two parties call each other; at a CCP the clearing house calls its members, and the members call their clients (the clearing broker model); the uncleared-margin rules (phased in 2016 to 2022) added daily VM and segregated IM to most dealer-to-dealer and dealer-to-large-fund relationships.
Collateral is a funding question: posting cash costs the bank its funding rate, posting gilts costs their repo rate and uses inventory; the optimizer and treasury’s choice are worth basis points a year on the whole book, and the cost is charged back to the desks as MVA.
Triparty agents (BNP Paribas Securities Services in the US) hold and value collateral for both parties under one agreement; repo, securities lending and increasingly IM collateral are handled this way; a bilateral delivery by SWIFT is the alternative for cash and simple portfolios.
One day in the bank’s account at the central bank. Operations forecasts the cash in and out from every settlement system, cash management manages the payments and the intraday balance, the funding desk borrows and lends to square the position, ALM sets the targets and charges the desks for the balance sheet they use, and liquidity risk stress-tests the whole. Every settlement and margin flow in the product sections lands somewhere in this cycle.

Time runs down one day: the forecast at the start, the morning funding, the intraday payment management, the end-of-day squaring, and the planning layer that sits above the days. The left column is the outside world the money moves through; everything else is inside the bank. The figures follow one day with a GBP 2.1bn shortfall.
United Kingdom: the bank funds through CHAPS with its reserves account at the Bank of England, the overnight market at SONIA, the Bank’s short-term and indexed long-term repo operations and the Discount Window Facility as backstop, cleared repo at LCH Ltd, and the wholesale markets (covered bonds, senior and MREL-eligible debt under the Banking Act); the PRA’s LCR and NSFR and the PRA110 reporting govern the liquidity ratios.
The central bank account at the Bank of England is the bank’s GBP cash: every CHAPS payment, CREST settlement, CCP margin and CLS pay-in moves it. Since 2008 banks hold large reserves instead of squaring to zero, and the Bank of England pays interest on them; the funding desk still manages the margin above target every day.
Intraday liquidity became a discipline after 2008 (Basel intraday monitoring, 2013): the bank must know its peak intraday usage and keep enough at the Bank of England, or collateral for daylight overdrafts, to make its time-critical payments; CLS and CCP deadlines are the hard points of the day.
Funds transfer pricing is the mechanism that connects this tab to every desk: a bond desk holding inventory pays treasury the repo rate plus a liquidity charge; a deposit desk earns a credit for stable deposits; prime brokerage pays for the balance sheet its clients use.
The ratios: the liquidity coverage ratio (30-day stressed outflows covered by high-quality liquid assets) and the net stable funding ratio (one-year structural funding) are reported to the regulator; the bank’s own stress tests and contingency funding plan sit on top, with the Discount Window Facility and the standing repo facility as backstops.
As clearing member the bank is broker and clearer of listed futures and options, not counterparty: it routes the client’s orders to the exchange under pre-trade limits, claims the trades given up by other brokers, clears them at the CCP in a customer account, calls and holds the client’s margin in segregated accounts, funds the CCP every morning, and handles expiries, deliveries and reporting. The clearing broker is responsible to the CCP for everything its clients do, so margin and limits run the business.

From the clearing agreement and the give-up setup, through order routing with a pre-trade check, give-ups and allocations, clearing and the CCP’s margin call, the client’s margin call and segregation, to expiries, deliveries and the daily segregation statement. The SONIA, gilt, index, energy, FX and agricultural futures products describe the trade; this view describes what the clearing broker runs behind it.
United Kingdom: the bank’s dealer clears ICE Futures Europe contracts at ICE Clear Europe and the LME contracts at LME Clear, and the global futures through its memberships or a US FCM; client margin and segregation follow UK EMIR’s segregation models (omnibus and individual) and the CASS rules or a title transfer arrangement; the US FCM rules apply to the US entity.
Roles: the executing broker fills the order, the clearing broker carries the position and the margin; many clients split the two (execute with several brokers, clear with one); give-ups and EGUS (the exchanges’ electronic give-up agreement system) exist for that purpose. The bank can be either or both.
Margin: the CCP calls the clearing member on its net customer positions; the clearing broker calls each client on its gross positions at the CCP’s rate or higher; the difference, and the clearing broker’s own residual interest, are the buffer. Customer funds are segregated at the clearing broker’s bank and at the CCP and cannot be used for the house or for another client.
Regulation: FCA authorisation for the clearing business and the PRA’s capital rules, the RTS 6 pre-trade risk controls, the daily client money reconciliations under CASS 7 and the monthly CMAR, the FCA’s position limits and position reporting; the MF Global (2011) administration in London, where client money was short, is the reason the CASS rules were tightened.
Economics: execution and clearing fees per contract, interest on customer cash balances above what is passed back, and the balance sheet and capital that customer margin and the default fund consume; clearing brokers therefore price large clients on their margin usage, not their volume.
Prime brokerage is how a hedge fund gets leverage and shorts: the prime broker settles and holds the fund’s positions, lends it cash against its longs (the margin loan), borrows stock for its shorts (the locate and the borrow), calls margin every day, and funds the whole book by re-using the client’s collateral and lending out inventory. The securities lending desk is the supply side; treasury is the balance sheet; PB operations runs the segregation rules that keep client assets safe.

Setup, then a long bought on margin and a short that needs a locate and a borrow, then the daily cycle of revaluation, margin calls, recalls and corporate actions, then the funding layer and the controls. Equity TRS (under Equities) is the synthetic version of the same business and Securities Lending (under Money Markets) the stock borrow trade itself; this view covers the business around them.
United Kingdom: the bank’s prime brokerage finances the hedge funds under the UK EMIR margin rules and the PRA’s capital rules, reuses collateral under title transfer arrangements or with the client’s express consent under CASS, borrows from the agent lenders and reports every loan under UK SFTR; the hedge fund managers sit in London, with the funds in Cayman, Ireland and Luxembourg.
The business: a prime broker clears, settles, finances and reports for hedge funds; the revenue is the financing spread on margin loans, the borrow fees on hard-to-borrow shorts, the spread on cash balances and the stock lending book; the risk is the client’s credit, managed by margin, and the funding of a large gross balance sheet.
Margin: the firm’s margin policy sets 50% initial margin on US equities for a cash or margin account; portfolio margin (since 2007) lets qualified clients margin on a stress-based net requirement, typically 15% to 25% of a hedged book; house rules sit above both and change with the client’s concentration and the market.
Securities lending: the supply of borrowable stock comes from long-only investors (pensions, mutual funds, ETFs) through their custodians as agent lenders, from other brokers, and from rehypothecated client longs; the borrow fee is the price of the short; UK SFTR has every loan reported to a trade repository by the next working day.
Segregation: the CASS rules require the broker to keep client fully-paid and excess-margin securities in client asset segregation and to lock up a cash reserve against client credit balances, computed daily or weekly; the reuse with consent cap is the US rule (the UK had none, which Lehman’s clients learned in 2008).
Inside the Bank›Risk, Finance, Compliance
Risk, Finance and Compliance Around the Desk
The independent functions that watch the desk: market risk measures and limits the positions, credit risk the counterparties, product control the P&L and the marks, compliance the conduct and the reports. They run on the same closing snapshot as the desk and give it back, every morning, a risk report, an official P&L and a list of alerts. The three lines of defense, drawn as one day plus the month end and the year.

The desk is on the left and the regulators on the right; in between, the four control functions in the order their work reaches the desk each morning. Before the trade they set the limits; during the day they watch; at the end of the day they measure; the next morning they report back; at month end they verify and close the books; through the year they are examined. The figures follow one credit desk for one day.
United Kingdom: the controls run under the PRA’s rulebook (the market risk rules, the trading book boundary, the Basel 3.1 standards), the PRA’s model risk principles, SYSC and the SMCR for the dealer, UK MAR’s surveillance duties, the UK EMIR and UK SFTR reporting, and the PRA’s and the FCA’s supervision; the bank’s compliance answers to the FCA, the PRA and the National Crime Agency.
Three lines of defense: the desk and its managers own the risk and the first checks (first line); market risk, credit risk, product control and compliance are independent of the business and report to the chief risk officer, the chief financial officer and the chief compliance officer (second line); internal audit tests both (third line).
Market risk: VaR is the common language (the loss not exceeded on 99 of 100 days), backed by sensitivities (DV01, CS01, vega, delta) and stress tests; since FRTB (2025 in the US) expected shortfall and risk-factor eligibility drive the capital charge, so the risk engine and the P&L attribution must agree.
Product control and valuation: the trader marks the book, but the official mark and P&L are finance’s; month-end price verification and reserves are where illiquid positions are challenged, and the P&L explain is where booking and model errors surface. The ledger produced here is what the regulators and auditors see.
Compliance and surveillance: the UK EMIR, MiFID and Market Abuse frameworks made trade and communication surveillance mandatory; regulatory trade reporting is executed by the middle office but owned by compliance, which reconciles what was reported to what was booked and answers the regulators.
Inside the Bank›Regulatory Reporting
Regulatory Reporting, From Transaction Reports to COREP
The reports the regulators receive from a trading business, organized by regime and deadline instead of by trade. Real-time trade reports (the APA, the APA, the APA, the trade repository price feed) within seconds or minutes; the T+2 records (transaction reporting, the full trade repository and the trade repository record, the Bank of England’s Sterling Money Market Data collection, the UK SFTR report); position and threshold reports; the periodic capital, liquidity and conduct returns. The reporting hub builds them from the bookings, reporting operations runs the daily cycle, compliance owns the obligations and finance and risk the returns. Completeness is the control: every reportable event has an accepted report.

One day on a credit desk followed into every regime it touches: the corporate bond trade to the APA within minutes, the equity hedge to the APA and to transaction reporting by the next morning, the CDS hedge to the trade repository, the positions into the threshold reports, and the same trades rolling into the month-end returns. Rejects go back to the source; completeness is reconciled by regime; failures are self-reported.
United Kingdom: the dealer reports every transaction to the FCA through an ARM by the next day, publishes its OTC and SI trades through an APA, reports its derivatives to a trade repository under UK EMIR and its financing transactions under UK SFTR, and keeps its order records; the bank files COREP, FINREP and PRA110 with the PRA, the statistical returns and the Sterling Money Market Data with the Bank of England and its suspicious activity reports with the National Crime Agency; there is no CAT, no TRACE and no FOCUS.
The regimes by product: equities to the consolidated tape (10 seconds) and transaction reporting (T+2); corporate, agency and securitized bonds to the APA (15 minutes, 1 minute for electronic trades from 2026); municipals to the APA (15 minutes); swaps to the FCA-registered trade repository (real-time price data, full record by T+2, daily valuation and collateral); derivatives reported under UK EMIR (single-name CDS, equity swaps on single names and narrow baskets) to the FCA’s the trade repository; securities loans to the UK SFTR report; the overnight rate to the Bank of England’s Sterling Money Market Data collection; gilt and repo positions to the OFR collections. Every product section names its regime in the facts table.
The reporting hub: one engine for all regimes is the goal; most banks have one per regime from the era it was built (the APA in 2002, the trade repository in 2013, transaction reporting in 2020) and a program to consolidate them; vendors (DTCC Report Hub, AxiomSL, Broadridge) sell the regime rules and the connectivity; the bank keeps the mapping from its bookings to the fields, which is where the errors come from.
Enforcement: regulators test completeness (every reportable trade reported), accuracy (the fields match the source) and timeliness (within the deadline), and fine the gaps: transaction reporting and the APA late-reporting cases, trade repository rewrite failures and the 2023 to 2025 off-channel communications settlements all fall on the reporting and record-keeping controls; a self-reported, remediated and back-reported failure is treated far more leniently than a found one.
Periodic returns are a finance process on the same data: the COREP and the market risk COREP for the holding company, the IFPR report and own funds for the investment firm, own funds and segregation for the clearing broker, the ALMM liquidity reporting for liquidity, the trading book boundary metrics per desk; each return has an owner, a reconciliation to the ledger and an attestation, and the regulators compare them with each other and with the trade reports.
