Level 1 lifecycle of each product from the asset manager’s point of view: the manager trades as agent for its funds and mandates, the custodian holds and settles, the administrator strikes the NAV, and dealers, brokers and clearing brokers sit on the other side of every trade. Columns are the parties, rows the phases from order to accounting; 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 (competitive or custodian, bilateral or sponsored, dealer or all-to-all), the lettered routes show them side by side. The Inside the Firm section covers the same flows from inside the manager, 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 buy-side page: the manager is the authorised fund manager of UK UCITS and NURS or a UK AIFM with a depositary, authorised by the FCA, 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 gilt market, settlement is T+2 until October 2027 (gilts already T+1), and the foreign products the fund trades (US credit, TBAs, loans) 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. GBP throughout; all numbers illustrative.

How the diagrams work, the lifecycle common to all 32 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.
Currency for a fund is a by-product of its securities and its investors: the FX needed to settle a foreign bond, the hedge of a share class sold in another currency, the NDF that hedges a local-currency bond, the option that protects a foreign equity book. The manager’s FX desk trades in competition on multi-dealer platforms or lets the custodian execute under a standing instruction; the custodian settles every leg, in CLS where it can, into the fund’s cash accounts.
OrderThe need for currency comes out of a securities trade, a hedge ratio or a flow; the OMS raises the FX and compliance checks the counterparty and the mandate.
ExecutionRFQ to several dealers on FXall, 360T or Bloomberg, netted across funds; or the custodian’s standing instruction at its fixing plus a spread.
Post-tradeMT300 confirmations per fund under each fund’s ISDA or FX master; forwards, NDFs and options reported to the trade repository by the dealer.
SettlementThe custodian settles both legs in CLS as a third party or gross on each currency’s rails, into the fund’s cash accounts.
Life and accountingForwards and options marked daily; collateral under the CSA through the custodian; the hedge P&L attributed to the share class; open currency priced at the London fixing for the NAV.
Where a fund’s cash lives. A money fund invests in bills, commercial paper, CDs and repo under the UK MMF rules; every other fund sweeps its residual cash into a money fund or repo through its custodian; a hedge fund finances positions in repo with its dealers; and any fund that holds securities can lend them through its custodian as agent lender. Same-day settlement and cut-offs frame the whole section.
OrderCash to invest or to raise, from subscriptions, redemptions and settlements; the UK MMF limits for a money fund, the cash policy for the others.
ExecutionDealer levels and RFQs for bills and paper in the morning; the custodian’s sweep and repo programs for residual cash; the agent lender’s desk for loans.
Post-tradePlatform or email confirmations; MRA confirmations for repo; the transfer agent’s register for money fund shares.
SettlementSame day: bills on CREST, CP and CDs through the ICSDs’ same-day settlement, triparty cash at BNP Paribas Securities Services, loans DVP at CREST, all through the custodian.
Maturity and accountingPar at maturity and a roll; amortized cost and a shadow NAV for a government money fund; lending income and collateral reconciled monthly.
Interest rate derivatives as a fund uses them: a cleared swap to add duration through the fund’s clearing broker, a bilateral swaption for a pension mandate under the uncleared margin rules, gilt futures as the fastest duration tool, and a cross-currency swap that turns a foreign bond into a synthetic domestic one. Every one is a margin flow the custodian moves and a position the derivatives rule counts.
OrderA duration or hedge target converted into a notional or a number of contracts; the COLL derivatives rules limits, the ISDA or clearing agreement and the dealer limits checked.
ExecutionRFQ on an MTF for cleared swaps with the clearing broker limit checked first; voice or Bloomberg for swaptions and cross-currency swaps; a broker algo on ICE Futures Europe for futures.
Post-tradeClearing at ICE Futures Europe or LCH through the clearing broker; Markitwire confirmations for bilateral trades; the dealer reports to the trade repository; give-ups for futures.
Clearing and settlementInitial margin at the clearing broker or, under the UK EMIR margin rules, at a segregated custodian; daily variation margin through the custodian; premium and principal exchanges as payments.
Life and accountingResets, coupons and rolls; compression or unwind; valuation from the CCP or the vendor; the UK UCITS reporting to the FCA and the COLL derivatives rules VaR.
Bonds and credit as a fund buys them. gilts by platform RFQ with bilateral or sponsored settlement; corporate bonds on MarketAxess and Tradeweb by dealer RFQ or all-to-all; new issues through the syndicate book; high yield by voice and distressed through a restructuring; sub-sovereign ladders for thousands of separately managed accounts; CDS cleared and bilateral; leveraged loans by assignment through the agent bank.
OrderThe analyst’s view becomes an order with issuer, sector, rating and liquidity limits tested; the trader checks the APA, the composite and the dealers’ axes.
ExecutionPlatform RFQ to several dealers, all-to-all, a voice trade, an order into a syndicate book, or a bid by voice for distressed and loans.
Post-tradeAllocation across funds at one price under the policy; CTM confirmation; the dealer’s APA print; LSTA documents on ClearPar for loans.
SettlementDVP through the custodian on CREST or at CREST on T+2, or sponsored at LCH Ltd; closing date for new issues; weeks on the agent’s register for loans.
Life and accountingCoupons and corporate actions through the custodian; credit monitoring; evaluated prices or the fair value committee; the liquidity buckets and the UK UCITS reporting to the FCA.
Mortgages and structured credit for a fund. Agency MBS through TBAs (a US market) rolled month after month under the MSFTA, with delivery of pools when the fund wants them; ABS and CMBS bought in new issues and by voice, modeled in Intex, settled at CREST as Eurobonds and run monthly through the trustee’s waterfall and factors.
OrderA sector weight or a deal the analyst has modeled; the MSFTA for TBAs (a US market), 144A eligibility and the liquidity bucket for the rest.
ExecutionPlatform RFQ for TBAs (a US market); the syndicate book for a new ABS; voice and BWIC checks for a CMBS tranche.
Post-tradeConfirmation under the MSFTA or through CTM; the dealer nets at LCH Ltd CREST on its own side; daily TBA margin from the trade date.
SettlementPool notification 48 hours ahead and DVP on CREST on the SIFMA date; CREST for private-label deals on T+2 or the closing date.
Life and accountingThe dollar roll; monthly principal and interest with factors; trustee reports and Intex reruns; valuation with factors and dealer quotes.
Stocks and their derivatives for a fund: an order worked by a broker’s algorithm, a program trade at the close for an index rebalance, a block sold on risk, index futures to equitize cash, a covered call overlay cleared at ICE Clear Europe, ETFs bought in the market or created through an authorized participant, total return swaps for a hedge fund through its prime broker, and an IPO allocation. Everything settles at CREST through the custodian on T+2.
OrderThe PM’s order across funds, with position limits and the restricted list tested; the trader chooses the broker and the strategy under the best execution policy.
ExecutionA broker algorithm across exchanges and dark pools, a program desk, a risk bid for a block, ICE Futures Europe for futures, the options exchanges, an AP for ETFs, the prime broker for swaps.
Post-tradeAllocation at the average price; CTM matching on trade date; give-ups to the clearing broker; ICE Clear Europe clearing; the broker’s tape and transaction reporting reports.
SettlementDVP at CREST through the custodian on T+2 with the broker’s side in the CCP; margin at the clearing broker or the prime broker; the closing date for an IPO.
Life and accountingDividends, corporate actions and proxy votes through the custodian; recalls from the lending program; expiry and assignment; the 16:00 close for the NAV; the quarterly holdings disclosure (none in the UK).
Commodities for a fund are futures and bills, or bars in a vault. A commodity index fund rolls two dozen contracts with the index every month through its executing broker and clearing brokers, watches position limits, and holds its money in bills; a gold fund buys allocated bars from LBMA dealers into a London vault and reconciles a bar list.
OrderThe index roll schedule or a creation converted into contracts or ounces; position limits, the clearing broker accounts, the trust’s indenture.
ExecutionTAS calendar spreads through the executing broker on Globex and ICE; RFQ to LBMA dealers for gold.
Post-tradeGive-ups to the clearing brokers and clearing; MT600 confirmation and allocation instructions for gold.
SettlementMargin in bills at the clearing brokers and daily variation through the custodian; bars allocated on the vault’s books against a wire on T+2.
Life and accountingThe monthly roll and the collateral yield; position limits; storage fees, bar lists and audits; NAV at the settlement prices or the LBMA price.
The same flows seen from inside the asset manager: who does what, in which system, in what order. Front to Back is the map. The foundations come first: a mandate must be onboarded and an instrument must exist in the security master before anything trades. The investment process runs from the model portfolio through the desk and compliance; operations settles, reconciles, margins, funds and accounts for it with the custodian and the administrator; oversight measures, reports and files. Columns are the firm’s own teams, with the outside world at the edges; the pills name the systems.
FoundationsA mandate or a fund is onboarded (agreements, accounts, coded guidelines) and every instrument, price and settlement instruction exists in the reference data before an order can be raised. Systems: OMS portfolio setup, compliance engine, security master, pricing engine, ALERT.
Investment processResearch becomes a model portfolio, the model becomes orders per account, compliance tests them, the desk executes under the best execution policy. Systems: research platform, portfolio system, OMS, EMS, TCA, compliance engine.
OperationsTrade support confirms and instructs; the custodian settles; operations reconciles, processes corporate actions, runs collateral and cash; the administrator strikes the NAV. Systems: CTM, SWIFT or the custodian portal, reconciliation tool, collateral system, cash forecast, accounting system, IBOR.
OversightPerformance measured and reported to clients, risk measured against limits and programs, filings built from the books. Systems: performance system, risk engine, reporting hub, data warehouse.
How to read a diagram
Columns are the partiesThe asset manager on the left, acting as agent for its funds and mandates, then the dealers and brokers it trades with, the custodian that holds and settles, the market infrastructure the custodian and the dealers reach, and the fund administrator that strikes the NAV. In the Inside the Firm section the columns are the manager’s own teams instead, with the outside world at the edges.
Rows are the phasesTime runs down the page: order, execution, post-trade, settlement, life of position, accounting. 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 statements; two-headed ones are exchanged or matched. 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 firm’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 ways (competitive or custodian FX, bilateral or sponsored settlement, dealer RFQ or all-to-all, secondary or creation), 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 decision tested against the mandate, a trade through a dealer or a broker, an agreement on the facts, settlement by the custodian, the maintenance of the position, and the accounting that produces the NAV. What changes is the venue, the confirmation platform, the settlement rail and how much the fund’s own operations have to do.

Inside the firm, 13 views
The same flows seen from the manager’s own teams: who does what, in which system. Front to Back is the map; the foundations (the mandate, the instrument, the price) come before any order; the investment process runs from the model to the desk; operations settles, margins, funds and accounts for it with the custodian and the administrator; oversight measures, reports and files.
Where each product trades, clears, settles and is reported
The same five questions for every product, from the fund’s side. Cleared means a clearing house stands between the fund (through its clearing broker) and the dealer after the trade; the cycle is the gap between the trade and the exchange of value. Reported says who files what: on the buy side most transaction reports are the dealer’s or the broker’s, and the fund’s own reports are about holdings.

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.
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.
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).
TCA: Transaction cost analysis: measuring execution quality against benchmarks (arrival price, VWAP, implementation shortfall) by broker, algorithm and venue.
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.
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).
Fund administrator: The service provider that keeps the fund’s official books, strikes the NAV and prepares financial statements; often a unit of the custodian bank.
NAV: Net asset value: the value of a fund’s assets less liabilities, per share, struck daily at the close for mutual funds and used for subscriptions and redemptions.
IBOR: Investment book of record: the manager’s own real-time view of positions and cash, including trades not yet settled, used for investment decisions.
ABOR: Accounting book of record: the fund administrator’s official positions and valuations, as opposed to the manager’s IBOR.
Mandate: The investment management agreement and guidelines that say what a portfolio may hold, in what size, with what risk; coded into the compliance engine.
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.
Client clearing: Access to a clearing house through a clearing member: the fund faces its clearing broker, which faces the CCP; the fund’s margin is segregated at the clearing broker and the CCP.
Agent lender: A custodian or specialist that lends a fund’s securities on its behalf, takes the collateral and shares the fee.
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.
Share-class hedging: Rolling currency forwards sized to the NAV of a share class so that its investors receive the fund’s return in their own currency.
Cash equitization: Using index futures to keep the fund’s cash balance invested in the market until the stocks are bought.
Market infrastructure, platforms and utilities
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.
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.

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.

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.
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.
Open Trading: MarketAxess’s all-to-all protocol: anonymous requests answered by dealers and other investors, with the platform’s investment firm as the counterparty.
FXall: LSEG’s multi-dealer FX platform where managers put dealers in competition for spot, forwards and swaps.
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.

Inside the firm: systems and filings
OMS: Order management system: where portfolio managers raise orders, compliance checks run and allocations across funds are kept (Aladdin, Charles River, SimCorp, Bloomberg AIM).
EMS: Execution management system: the trading desk’s tool for routing orders to brokers, algorithms and venues and watching fills (FlexTrade, Bloomberg EMSX, Tradeweb and MarketAxess for bonds).
Compliance engine: The rules engine that checks every order and every position against the fund’s mandate, the regulations and the restricted lists, before and after the trade.
Portfolio system: The portfolio manager’s view of positions, exposures and models, fed by the IBOR.
Risk engine: Computes end-of-day and intraday sensitivities, VaR and stress results from the trade population and market data; in-house, or the risk module of the trade capture system.
Accounting system: The fund administrator’s book of record (ABOR): settled and accrued positions, valuations and the NAV; reconciled daily to the custodian and the IBOR.
Performance system: Computes returns, attribution and risk statistics from the accounting data for client reporting and GIPS composites.
Data warehouse: The manager’s central store of positions, transactions, prices and reference data feeding reporting and analytics.
Security master: The bank’s one record per instrument: identifiers, terms, calendars and classifications, read by every system that books, prices, settles or reports a trade.
Pricing engine: The desk’s automated pricer: builds quotes from market data, the curve or vol surface and the inventory, and answers small electronic RFQs without a human.
Custody portal: The custodian’s web platform where the manager instructs, monitors settlements, views cash and holdings and handles corporate actions.
Client portal: The manager’s reporting platform for its clients: holdings, performance, risk and documents.
FCM portal: The clearing broker’s client portal: cleared positions, margin calls, statements and fees for the fund’s futures and cleared swaps.
Prime portal: The bank’s prime brokerage client platform for financing, margin and reporting.
Trade file: A batch file of trades or positions exchanged between the manager, a custodian or a sponsor platform when no messaging standard applies.
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.
Collateral system: Holds every CSA’s terms, computes the daily margin calls, tracks collateral balances, disputes and substitutions (Calypso, Murex, CloudMargin, Acadia).
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).
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).
UK AIFMD: The onshored AIFMD: the authorisation of the UK AIFMs, the depositary, the risk and liquidity management, the Annex IV reporting to the FCA and the marketing under the national private placement regime; the FCA’s 2025 review proposes a simpler regime by size.
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.
COLL: The FCA’s Collective Investment Schemes sourcebook: the rules for UK UCITS, NURS and QIS funds (the authorisation, the investment limits, the pricing and dealing, the depositary, the reports), with the assessment of value and the liquidity management rules.
Subscriptions and redemptions: Investors buying or selling fund shares at the NAV through the transfer agent; the resulting cash flows drive the fund’s daily trading.
Local terms, rules and institutions
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.
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.
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.
UK UCITS: The onshored UCITS regime under COLL: the authorised funds (OEICs and unit trusts) a UK management company runs with a depositary, with the investment and borrowing limits, the pricing rules and the liquidity tools; the NURS (non-UCITS retail scheme) and the QIS sit beside it, and the UK and EU UCITS no longer passport.
LTAF: The Long-Term Asset Fund, the FCA’s open-ended fund for illiquid assets (2021), with notice periods and the valuation rules, open to retail clients as a restricted mass market investment since 2023 and to the defined contribution pension schemes; the UK counterpart of the ELTIF.
Investment trust: A closed-ended company listed on the London Stock Exchange that invests in a portfolio (equities, property, private equity, infrastructure), bought and sold like a share at a premium or discount to its net asset value; the UK’s oldest fund structure and the retail route into illiquid assets.
LDI: Liability-driven investment: the hedging of a defined benefit pension scheme’s liabilities with gilts, swaps and repo-financed leverage, run by the LDI managers; the 2022 gilt crisis, when the scheme’s collateral calls forced gilt sales and the Bank of England intervened, reshaped the leverage limits and the collateral buffers.
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.
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 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.
ICE Futures Europe: ICE’s London derivatives exchange (the former LIFFE and IPE): Brent and gasoil, the gilt and SONIA futures, the FTSE 100 futures and options and the UK single stock options; cleared at ICE Clear Europe.
LME: The London Metal Exchange, the base metals exchange (copper, aluminium, nickel, zinc) with its prompt dates and warehouses, cleared at LME Clear.
LSE: The London Stock Exchange: the Main Market and AIM, the SETS order book for the liquid shares, the closing auction, the retail service provider network for retail orders and the order book for retail bonds (ORB); cleared at LCH Ltd and settled in CREST.
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.
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.
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.
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.
Gilt futures: The long gilt, medium gilt and short gilt futures on ICE Futures Europe, cleared at ICE Clear Europe, with the conversion factors and the cheapest to deliver of the US model; the duration tool of the UK pension funds and the LDI managers.
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.

FX Spot for a Securities Settlement, Competitive and Custodian
A fund buying a foreign security needs the currency for settlement. The manager’s FX desk either puts dealers in competition on a multi-dealer platform (C), netting the day’s flows across funds first, or lets the custodian execute under a standing instruction at its fixing plus a spread (S). The custodian settles both legs, in CLS where it can, into the fund’s cash accounts, and the administrator prices the positions for the NAV.
Worked example, illustrative:fund needs EUR 10,000,000 vs GBP, value T+2, for a bond settlementC, quotes 1.0853 to 1.0855 from 4 dealersC, done 1.0853 with dealer AS, custodian 1.0862: fixing plus spread, 9 pips widersettlement CLS third party through the custodian, or grossNAV open currency at the 16:00 London fixing

The order comes out of a bond trade, not a currency view. The competitive route costs a few pips less and needs an FX desk, platform access and an FX master or ISDA per fund; the custodian route costs more and needs nothing. Both end in the fund’s cash accounts at the custodian, and the manager’s transaction cost analysis keeps score between them.
United Kingdom: the fund settles its foreign securities through its depositary’s global network; GBP/USD is the pair of most trades, settled in CLS through the depositary or the dealer; the UK banks and the global banks are the counterparties.
Who trades FX at a manager: a central FX desk for the large firms, trading on FXall, 360T, Bloomberg FXGO and FX Connect with netting across funds; smaller managers and most custody-driven flows (income repatriation, small settlements, restricted currencies) go through the custodian’s standing-instruction program at a disclosed markup.
The custodian FX cases of 2009 to 2015 (BNP Paribas Securities Services and State Street settled for over GBP 1 billion over undisclosed markups on standing-instruction FX) are the reason the custodian’s rate and spread are now disclosed, benchmarked and reviewed in the manager’s TCA.
Settlement: the fund is not a CLS member; its custodian settles the fund’s trades in CLS as a third party through a settlement member where the dealer agrees, and gross otherwise, so the fund carries settlement risk on the dealer for gross trades on the value date.
Documentation: each fund signs its own FX master or ISDA with each dealer; the manager trades as agent and allocates; the dealer’s credit line is on the fund, so the counterparty list and the settlement lines are checked before the RFQ.
Share-Class Currency Hedge, Rolling One-Month Forwards
A fund that is managed in GBP and sold to EUR investors hedges the EUR share class with rolling forwards sized to that class’s NAV. The program recomputes the hedge daily, trades the forward in competition, posts and receives collateral under the CSA with the dealer, and rolls the forward every month with an FX swap; the hedge P&L is cash in the share class and offsets its currency translation.
Worked example, illustrative:hedged class EUR 400,000,000 of NAV at 100% ± 2%forward sell EUR 400m, 1 month, 1.08695points +19 / +20VM a 2% EUR move is GBP 8.7m of collateralroll FX swap two days before value; net GBP settlementNAV hedge P&L to the EUR class only

Jump to16 steps, hover or click any of them
The size comes from the NAV, not from a view. The trade is a forward in competition, the life is daily marking and collateral, and the end of each month is a roll rather than a settlement: the maturing forward is bought back and a new one sold in one swap, and only the difference moves in cash. The accounting keeps the hedge in the share class it belongs to.
United Kingdom: the hedged share classes of UK authorised funds run the same rolling forward program under COLL and the FCA’s guidance on hedged classes (the hedge kept within 95 to 105%); the forwards are reported to a trade repository under UK EMIR.
Share-class hedging (UCITS and US funds sold abroad) and portfolio hedging (a GBP fund hedging its foreign bond holdings) use the same machinery; passive programs run to a rule (100% of the class NAV, rebalanced daily or at a threshold), overlay managers run them for several funds at once.
Collateral: a fund under the uncleared-margin rules posts and receives daily variation margin under its CSA; FX forwards are exempt from initial margin in the US; the collateral sits at the custodian in accounts segregated per fund and per dealer; a rally in the hedged currency can mean large collateral calls for cash the fund must hold or raise.
The roll: an FX swap (buy back the maturing forward, sell a new one) with the same dealer nets the currency legs so only the P&L settles; with a different dealer both legs settle gross on the value date through the custodian, which doubles the settlement flows and the CLS usage.
Economics: the hedged class earns the fund’s return plus the interest differential embedded in the forward points (positive for EUR investors in a GBP fund when GBP rates are higher), less the roll costs and the collateral drag; prospectuses disclose the expected hedging error.
Non-Deliverable Forward, Hedging a Local-Currency Bond
An emerging-market debt fund hedges part of a local-currency bond position with an NDF: the currency cannot be delivered offshore, so the forward settles in USD on the difference between the contract rate and the official fixing. The fund trades it in competition under its ISDA with EMTA terms, posts variation margin as the mark moves, and receives or pays one USD amount at the end, through its custodian.
Worked example, illustrative:fund hedges BRL 250,000,000 of a 500m bond position, 3 monthsquotes 5.2235 to 5.2250done 5.2235 with dealer C, USD 47.86mfixing PTAX 5.3000settlement USD 690,819 received by the fundVM daily under the CSA

The order is a hedge ratio decision by the portfolio manager; the execution is a three-dealer RFQ; the life is marking and collateral; the end is a fixing the manager verifies and a single USD receipt the custodian matches. The NAV shows the hedge gain against the bond’s currency loss.
United Kingdom: the NDF is traded with the global banks and reported to a trade repository under UK EMIR; NDFs are in the UK EMIR margin rules for variation margin; the depositary settles the USD.
EM debt funds hedge selectively: the carry in the local bond is partly the currency risk premium, so a full hedge gives up return; hedge ratios are an active decision and the NDF is the only instrument for most of these currencies (BRL, CNY onshore, INR, KRW, TWD, IDR).
Documentation: EMTA template terms per currency in the fund’s ISDA confirmations (fixing source and time, valuation and settlement dates, unscheduled holiday and price-source disruption fallbacks); the fund is never the reporting party against a swap dealer.
Margin: NDFs are not exempt from the uncleared-margin rules: daily VM under the CSA for every fund, IM segregated at a custodian for funds above the AANA thresholds (USD 8 billion); clearing at LCH ForexClear is available through a clearing broker but rarely used by funds.
Operations: the manager verifies every fixing against the published source before agreeing the settlement amount; the custodian is pre-advised to expect the receipt; a dispute on the fixing or the amount is the commonest NDF operational issue.
A fund buys a currency put to protect the USD value of a European equity position without giving up the upside. The premium is paid once through the custodian, the dealer posts collateral to the fund as the option gains, and at expiry the fund elects cash settlement and receives one USD amount. The option’s delta counts in the fund’s hedge ratio throughout.
Worked example, illustrative:fund buys 6-month EUR put, strike 1.0525, EUR 300,000,000vols 6.4 to 6.5premium 0.95%, USD 3,092,250delta about 35% of the position hedgedexpiry 1.0300: USD 6,750,000 received, cash settled

An RFQ on volatility, a premium payment, six months of marking with collateral flowing from the dealer, and a cash settlement the manager elects at expiry. The fund never delivers currency, and the payout lands in the same account the stocks are valued in.
United Kingdom: the option is under the fund’s ISDA with a UK or global bank, reported to a trade repository under UK EMIR; the margin follows the UK EMIR margin rules (variation margin for all, initial margin above the thresholds).
Options are the hedge for managers who want protection without the symmetric give-up of a forward: put protection, collars (a put paid for by a sold call, which needs a margin line for the fund), participating forwards; prospectus and mandate language usually limit options to hedging and cap the premium.
Credit: the fund that buys an option has credit exposure to the dealer for the option’s value, so the dealer posts VM to the fund under the CSA; a sold option reverses it and the fund posts; the collateral sits at the custodian in the fund’s name.
Cash versus delivery: a fund hedging a securities position elects cash settlement so the hedge pays without moving the underlying currency; a fund hedging a known future cash flow may take delivery and use the currency.
Valuation: options are marked from dealer quotes or a vendor vol surface for the NAV; the administrator’s pricing policy names the source and the fallback; a long-dated or exotic option is where pricing disputes between manager and administrator arise.
UK Treasury Bills for a Money Market Fund, Tender and Secondary
A government money fund invests subscription cash in UK Treasury bills, either in the secondary market by RFQ to dealers (S) or at the weekly tender through a dealer (P). The custodian receives the bills on CREST against the fund’s cash, the fund accretes them to par at amortized cost under the UK MMF rules, and the administrator shadow-prices the portfolio against the stable GBP 1.00.
Worked example, illustrative:fund invests GBP 200,000,000 in the 3-month billS, offers 3.954% to 3.957% yield; done at 3.957%, price 99.0231P, bid 3.960% through the dealer; highest accepted 3.962%, filled in fullsettlement T+1 or issue date, CREST via the custodianaccounting amortized cost; shadow NAV daily2a-7 WAM 60 days, WAL 120, liquidity buckets

Jump to16 steps, hover or click any of them
The order starts from cash and the UK MMF limits, not from a market view. Secondary bills are bought in competition on a platform; tender bills through a dealer’s bid; both arrive at the custodian on CREST. The fund accretes the discount to par and the administrator checks the stable NAV against market prices every day.
United Kingdom: the DMO sells one, three and six-month bills at the weekly Friday tender, bid by the Treasury bill primary participants (the banks and the gilt-edged market makers), with a fund bidding through a dealer; bills settle at CREST on T+1; the UK MMF rules (the onshored MMF Regulation the FCA is reforming) govern the fund’s types, liquidity floors and maturity limits.
The sterling money market funds (about GBP 250 billion, most of them Irish or Luxembourg funds sold into the UK under the overseas funds regime, with the UK MMF rules for the domestic ones) hold bills, deposits, CP and repo under the MMF rules: weighted average maturity 60 days, weighted average life 120 days, daily and weekly liquid asset floors, and a stable GBP 1.00 NAV at amortised cost with a daily shadow price for the low-volatility funds.
Buying bills: secondary RFQ on Tradeweb and Bloomberg to the bank dealers, or the weekly tender through a UK Treasury bill primary participant (the fund’s bid goes in the dealer’s submission to the DMO); tenders are bid-yield, so every award pays its own price.
Settlement: the fund holds its bills at its custodian, a CREST member; DVP in CREST against the fund’s cash at the custodian; T+1 or same day for secondary trades.
Clearing: there is no clearing mandate for gilts or bills in the UK; a fund that wants cleared repo reaches LCH Ltd through sponsored clearing at LCH Ltd, which the sterling money funds use for their reverse repo.
Sterling Commercial Paper and Certificates of Deposit for a Money Market Fund
A prime money fund buys short unsecured paper each morning from the dealers’ posted levels: commercial paper created at CREST by the issuer’s agent and certificates of deposit issued by banks, settling the same day through CREST’s money market instrument program into the fund’s custodian account. Thirty days later the paper matures at par and the cash rolls. The UK MMF credit and liquidity rules limits frame every order.
Worked example, illustrative:fund invests GBP 30,000,000 CP at 5.30% and GBP 20,000,000 CD at 5.32%, 30 dayssettlement same day, CREST the ICSDs’ same-day settlement via the custodianmaturity par plus interest through CREST in 30 days2a-7 eligible issuers, 5% per issuer, liquidity bucketsNAV floating to four decimals for institutional prime funds

The dealers post, the fund orders, the agent creates the paper at CREST and the custodian receives it against cash before the afternoon cut-off. The life is a credit watch; the end is par through CREST. Everything is same-day, so the cash forecast and the CREST cut-offs run the morning.
United Kingdom: sterling commercial paper and the banks’ certificates of deposit settle at CREST, euro commercial paper at the ICSDs, same day or T+1; the UK MMF rules set the credit assessment and the diversification, and the fund’s sterling book is mostly the banks’ and the corporates’ short paper and the deposits.
Prime money funds hold CP, CDs, time deposits and repo of banks and corporates; after the 2016 and 2023 reforms institutional prime funds float their NAV and carry liquidity fees, and the sector shrank in favor of government funds; the remaining prime funds and the separately managed cash accounts of corporates are the main CP buyers.
Settlement: ECP and CDs are ICSD instruments; the issuing and paying agent creates the notes on issue date and pays them at maturity; trades settle same day with the ICSDs’ cut-offs in the afternoon; the fund’s custodian is the CREST participant.
Credit: the fund’s own credit team approves issuers and sets limits; The UK MMF rules require an internal credit assessment for every holding, diversification and a board process for downgrades and defaults; the 2008 Reserve Primary Fund break (Lehman CP) is the case the rules were written against.
Reporting: monthly the UK MMF rules reporting filings of every holding to the FCA, public on a lag; daily liquidity and weekly liquid asset disclosures on the fund’s website.
Money Markets›Cash Sweep
Cash Sweep Into a Money Market Fund
A fund’s residual cash is swept each evening into a government money market fund through the custodian, above a buffer the cash forecast sets, and redeemed the same day when a settlement needs it. The money fund is a holding of the fund, valued at its stable NAV with a daily dividend; the transfer agent issues and cancels the shares. For most funds this is the cash management product, with no trading desk involved.
Worked example, illustrative:residual cash GBP 12,000,000; buffer GBP 4,000,000sweep GBP 8,000,000 subscribed at GBP 1.00 before the 13:00 London time cut-offreturn the SONIA rate less the expense ratio, accrued dailyredemption GBP 5,000,000 same day for tomorrow’s settlementaccounting a holding valued at GBP 1.00; acquired fund fee disclosed

Jump to10 steps, hover or click any of them
No order, no RFQ: a standing instruction and a daily cash forecast. The custodian subscribes and redeems through the transfer agent by the money fund’s cut-offs, the shares sit in the custody account, and the administrator reconciles them to the register. The whole product is cut-offs and forecasts.
United Kingdom: the fund’s uninvested cash sits with the depositary (where the COLL deposit limits apply: 20% per bank for a UCITS) or in a money market fund of the same group under the UK MMF rules.
Why a sweep: a fund cannot leave cash uninvested (it dilutes return) and cannot buy bills for every day’s residual; a government money fund gives same-day liquidity at the SONIA rate less 10 to 20 basis points; custodians run cash placement into their own or third-party money funds, and the choice of fund and the fee are a governance point for the fund’s board.
Cut-offs run the product: government money funds offer multiple intraday NAV strikes with a late final cut-off (13:00 London time or later) so that end-of-day cash can still be placed; the custodian’s own cut-off is earlier; a sweep that misses the cut-off leaves the cash overnight at the custodian’s deposit rate.
Alternatives: overnight repo with a dealer through the custodian (used by larger funds and for larger balances), bank deposits (counterparty limits apply), and direct bill purchases; many funds use all of them under a cash policy with concentration limits per money fund and bank.
The COLL fund-of-funds limits (20% in one fund for a UCITS, 30% in non-UCITS funds) cap a fund’s investments in other funds; money market funds are the usual exception; the acquired fund’s charges appear in the investing fund’s ongoing charges figure.
Repo From the Fund’s Side, Investing Cash and Financing Positions
Repo serves the buy side in two directions. A money fund invests cash overnight in reverse repo against gilt collateral held for it by the triparty agent, increasingly through a dealer that sponsors it into LCH Ltd (I). A hedge fund finances a bond position by repoing it with its dealer for cash, posting a haircut and daily margin (L). In both the custodian moves the cash or the bonds and the fund’s books show a cash equivalent or a liability.
Worked example, illustrative:I, fund invests GBP 500,000,000 overnight with 3 dealers at 5.31% to 5.32%; sponsored at 5.33%I, collateral gilts at 102% in the fund’s triparty accountI, interest about GBP 73,800 overnightL, fund finances GBP 300,000,000 of a 10-year note, 1 week at 5.35%, 2% haircut: GBP 294m of cashL, interest GBP 306,000 for the weekdocumentation MRA per dealer; LCH Ltd sponsored terms
Routes:Ireverse repo, the fund invests cash against gilt collateral in tripartyLrepo, a hedge fund finances a gilt position through its prime or repo dealer1shared steps

Jump to14 steps, hover or click any of them
On the investing route the fund never touches the collateral: the triparty agent allocates, values and holds it, and the custodian moves the cash. On the financing route the fund’s custodian delivers the bonds and the dealer margins them daily. Sponsored clearing puts LCH Ltd between the fund and the dealer on either route, which LCH Ltd RepoClear already provides for most of the gilt repo market.
United Kingdom: repo is documented under the GMRA and priced off SONIA; gilt repo clears at LCH Ltd RepoClear (the £GC and term £GC baskets for the cleared general collateral), with the funds reaching the CCP through clearing members or LCH’s sponsored clearing; Euroclear Bank, BNY and J.P. Morgan run the triparty; every repo is reported under UK SFTR, and the Bank of England collects the market’s daily data.
Money funds are the largest repo cash lenders (over GBP 2 trillion), mostly in triparty against gilt and agency collateral, and the main users of LCH Ltd sponsored clearing at LCH Ltd; the Bank of England’s reserves rate sets the floor on their rate; counterparty limits per dealer and the LCH Ltd guarantee are the credit controls.
Hedge funds and relative-value strategies finance gilt positions in bilateral repo with their prime or repo dealers at haircuts of 0 to 2% (the basis trade of 2023 to 2025 ran on this), and the banks’ balance sheet costs move most of it into LCH Ltd through sponsored clearing at LCH Ltd; the haircut, the term and the roll are the fund’s liquidity risk.
Documentation and operations: a master repurchase agreement per dealer; triparty through BNP Paribas Securities Services with instructions matched on its platform; bilateral repo settles DVP on CREST through the custodian; the fund’s accounting treats reverse repo as a cash equivalent and repo as a borrowing, and the Annex IV report under UK AIFMD and the UK UCITS reporting to the FCA report both.
The UK MMF rules treat gilt repo as a daily liquid asset if it can be unwound on demand; the collateral schedule, the haircut and the counterparty are reviewed by the fund’s credit team; a dealer default means the fund keeps and sells the collateral, so gilts at 102% are the standard.
Money Markets›Securities Lending
Securities Lending, the Fund as Lender Through Its Agent
A fund earns a few basis points a year by lending the securities it holds. The custodian, as agent lender, lends them to investment firms against cash collateral at 102%, reinvests the cash, marks the loans daily, collects the fees and manufactured dividends, and recalls the shares when the manager sells or wants to vote. The manager sets the program and sees the reports; the agent runs the loans and indemnifies the fund against a borrower default.
Worked example, illustrative:program agent lender, cash collateral 102%, fee split 80 / 20, borrower limits, exclusionsloan 500,000 shares of a hard-to-borrow mid-cap at a 3% feecollateral cash at 102%, reinvested; marked dailyincome reinvestment yield less rebate, plus the fee; a few basis points a year on the fundrecall for a sale or a proxy vote, T+2

Setup, then loans the agent makes without asking, then a daily cycle of marks, collateral and income, then recalls when the fund needs its shares back. The fund keeps the economic return and the risk of the collateral reinvestment; the agent keeps a share of the fee and takes the borrower risk.
United Kingdom: the fund lends through its depositary or an agent lender within the COLL efficient portfolio management rules (the collateral and reinvestment restrictions of the FCA’s guidance); the loans are reported loan by loan under UK SFTR; the borrowers are the banks and the prime brokers.
Supply: mutual funds, ETFs, pensions and insurers lend through their custodians (BNP Paribas Securities Services, State Street, JPMorgan, Northern Trust) or third-party agents, which run pooled programs across clients; demand comes from investment firms covering shorts and fails and from prime brokers for their hedge fund clients; the fee is the price of the borrow and most of the income on a large-cap fund comes from a few hard-to-borrow names.
Risks the fund keeps: collateral reinvestment (the 2008 losses in cash collateral pools were the lenders’, not the borrowers’), the recall and proxy voting trade-off, and operational risk on recalls; the agent’s indemnity covers borrower default (collateral shortfall), not reinvestment.
Regulation: UK SFTR has every loan reported to a trade repository by both counterparties (the lender’s side usually delegated to the agent) by the next working day; registered funds disclose securities on loan, collateral and income in the UK UCITS reporting to the FCA and the financial statements; COLL limits lending to a third of a fund’s assets and requires the board to oversee the program and the fee split.
ETFs and index funds are the largest lenders and treat the income as a return enhancement that offsets fees; active managers often restrict lending on names they may sell or vote; some funds opt out entirely.
Cleared SONIA Interest Rate Swap Through a Clearing Broker
A bond fund adds duration with a receive-fixed SONIA swap traded on an MTF or OTF and cleared at ICE Futures Europe through the fund’s clearing broker. The clearing broker holds the fund’s initial margin in segregation, passes the daily variation margin, and settles the coupons; the fund can unwind with any dealer because the trade sits at the CCP. The COLL derivatives rules and the fund’s cash forecast frame the position.
Worked example, illustrative:fund wants +2 years duration: GBP 100,000,000 10-year receive-fixedquotes 3.512% to 3.514%; done at 3.514%DV01 about GBP 85,000 per bpIM at the clearing broker about GBP 3,500,000 plus add-onVM 10 bp is GBP 850,000 a daythe COLL derivatives rules VaR within the limit; reported to the board

Jump to15 steps, hover or click any of them
The fund never faces the dealer after the trade: the trading venue, the clearing broker and the CCP take over at execution, and the fund’s relationships are its clearing broker (limits, margin, statements) and its custodian (moving the margin). The daily margin is cash the fund must have, so the cash forecast and the collateral desk see every swap.
United Kingdom: SONIA swaps are subject to the UK EMIR clearing obligation and the UK derivatives trading obligation for the standard tenors; they clear at LCH SwapClear through a clearing broker, and both counterparties report to a trade repository under UK EMIR (the Refit formats since 2024).
Rule the COLL derivatives rules (2022) lets a registered fund use derivatives under a VaR-based limit (150% of a reference portfolio’s VaR or 20% absolute) with a derivatives risk manager and board reporting; limited users under 10% of net assets are exempt from the VaR test; the rule replaced asset segregation.
Clearing: the fund is a client of a clearing broker (the bank’s futures and cleared swaps business) under a cleared derivatives addendum; the clearing broker guarantees the fund to the CCP, calls margin and holds it in LSOC segregation (legally segregated, operationally commingled); the fund’s exposure to the clearing broker is the excess margin and the operational dependency.
Execution: swaps subject to the trading obligation must trade on a regulated market, an MTF or an OTF, by RFQ or on an order book; the fund can trade a block off-MTF above the block size; packages, compression and portability between clearing brokers are the operational topics.
Why not bonds: a swap adds duration without cash, keeps the fund’s credit exposure in bonds, and can be reversed in minutes; the costs are margin (cash drag), the clearing broker fees and the swap spread basis against gilts.
Bilateral Swaption for a Pension Scheme Under the UK EMIR Margin Rules
A liability-driven mandate buys a receiver swaption to protect a pension plan against lower rates. Swaptions are not cleared, so the trade is bilateral under the mandate’s ISDA: daily variation margin under the CSA and, because the plan is above the uncleared margin threshold, two-way initial margin computed with SIMM and posted to segregated accounts. At expiry the in-the-money option exercises into a cleared swap at the mandate’s clearing broker.
Worked example, illustrative:mandate buys 1y10y receiver swaption, strike 3.60%, GBP 250,000,000premium 255 bp, GBP 6,375,000 on T+2VM daily under the CSA, cash or giltsIM about GBP 9,000,000 SIMM, segregated, two-wayexpiry swap rate 3.20%: exercised into a cleared swap at the clearing broker

Bilateral means the dealer relationship stays live for a year: confirmations, daily marks and VM, and under the UK EMIR margin rules a second margin that neither side can use. The exercise moves the resulting swap into clearing, so the operational model changes on expiry day from CSA and custodian to clearing broker and CCP.
United Kingdom: the swaption is under the pension scheme’s ISDA with a bank; variation margin is exchanged under the UK EMIR margin rules and initial margin above the threshold; the pension schemes’ clearing exemption was extended to 2027, so their swaps clear voluntarily; after the 2022 gilt crisis the LDI managers hold collateral buffers under the Bank of England’s resilience standard; the trade is reported to a trade repository.
Uncleared margin rules: since phase 6 (2022) any entity with over GBP 8 billion of average aggregate notional in uncleared derivatives exchanges two-way initial margin with its dealers; large pension plans, insurers and the biggest funds are in scope; the margin is computed with ISDA SIMM, posted to a segregated custodian account or triparty, and cannot be rehypothecated.
Operations for an in-scope manager: IM calculation and reconciliation on AcadiaSoft, custody arrangements with the dealer’s and the fund’s custodians (account control agreements), monitoring of the GBP 50 million threshold per counterparty group below which IM need not move, and the choice between bilateral and voluntary clearing to avoid the IM cost.
LDI: pension mandates hedge the interest rate and inflation sensitivity of the plan’s liabilities with swaps, swaptions and long bonds; the hedge ratio, the collateral waterfall and the liquidity buffer for margin calls are the mandate’s governing parameters; the UK gilt crisis of 2022 was an LDI margin-call event.
Valuation: swaptions are valued off the dealer’s and the manager’s vol surfaces; the administrator uses vendor prices (Bloomberg, Refinitiv) with a dealer quote as a check; disputes over VM are resolved on Acadia within the CSA’s dispute process.
A bond fund changes its duration for a week by selling gilts futures through an executing broker’s algo on ICE Futures Europe, given up to the fund’s clearing broker. The clearing broker holds the initial margin in segregation and passes the daily variation margin, which the custodian wires; the fund buys the contracts back after the event. Futures are the fastest and cheapest duration tool a fund has, and the margin is the only cash involved.
Worked example, illustrative:fund wants -0.5 years of duration for a week: sell 900 ZNexecution broker algo on ICE Futures Europe, average 110-17.5give-up to the fund’s clearing broker under EGUSIM about GBP 2,100 per contract, GBP 1,890,000VM 1 point is GBP 900,000 a dayclose bought back after the Monetary Policy Committee; margin released

Execution and clearing are split: an executing broker works the order, the clearing broker holds the position and the margin. The fund sees the fills in its EMS within minutes and the clearing broker statement the next morning, and its custodian moves the margin cash every day. Nothing else moves until the position is closed or rolled.
United Kingdom: the long gilt futures (and the medium and short gilt contracts) trade on ICE Futures Europe and clear at ICE Clear Europe through the fund’s clearing broker; the overlay runs under the COLL global exposure rules (commitment or VaR) or the pension scheme’s policy.
Executing broker and clearing broker: a fund typically clears all its futures at one or two clearing brokers and executes with several brokers, who give the trades up under a three-way give-up agreement documented on EGUS; the executing broker charges a commission, the clearing broker a clearing fee and the margin interest.
Margin: ICE Futures Europe SPAN (now SPAN 2) sets the initial margin; the clearing broker may add a buffer; the margin sits in a 4d(a) customer segregated account at the clearing broker, invested in gilts or cash; variation margin settles twice a day at the CCP and daily with the client; the fund’s treasury sizes a margin buffer for a stress move.
Rolls and delivery: a fund that keeps a position across the quarterly expiry rolls it with a calendar spread before first notice day; a fund that fails to roll a long can be delivered gilts, which the operations desk avoids with a hard calendar; the roll cost (the calendar spread) is part of the overlay’s cost.
Why futures: no cash, no ISDA, no dealer line, one-minute execution and a visible price; the limits are the contract grid (2, 5, 10, 20, 30 year), the basis against the fund’s actual bonds, and the margin cash drag, which the fund offsets by holding gilts as margin.
A global bond fund hedges a EUR bond into USD with a cross-currency swap that exchanges the principal at the start and the end and swaps the coupons for five years. The swap is bilateral under the fund’s ISDA with daily variation margin; the custodian settles the principal and coupon exchanges and moves the collateral. The swap is linked to the bond in the fund’s books and unwound if the bond is sold.
Worked example, illustrative:fund hedges EUR 50,000,000 5-year bond into USDswap pay EUR 3.10%, receive USD 4.92%, principal exchanged at 1.0850basis about -20 bp EUR/USD in the priceVM a 5% EUR move is USD 2.7m of collateralcoupons EUR 1,550,000 out, USD 2,669,100 in, yearlyfinal EUR 50m out, USD 54.25m in at year 5

The swap turns a EUR bond into a synthetic USD bond for the fund. The flows are heavier than a forward: principal exchanged twice, coupons swapped every year, collateral every day, all through the custodian. A rolling forward hedge is simpler and more common; the cross-currency swap fixes the basis for the bond’s life.
United Kingdom: the diagram keeps the US example (a EUR bond hedged into USD); a sterling fund hedges its foreign bonds back to pounds the same way, under its ISDA with a UK or global bank, reported under UK EMIR, with the hedged share classes using it alongside the forwards.
Cross-currency swaps are not mandated for clearing (the principal exchange makes them hard to clear) and stay bilateral under the ISDA, with VM under the CSA and IM under the UK EMIR margin rules for in-scope funds; some managers clear the interest rate component and leave only the FX legs bilateral.
When a fund uses one: to hedge a foreign bond for its life at a fixed basis, to fund in one currency and invest in another, or because a long-dated forward is illiquid; most mutual funds hedge with rolling 1- to 3-month forwards instead and accept the basis roll.
Operations: principal and coupon exchanges are payment instructions the custodian executes against the fund’s cash accounts; the collateral desk runs the daily VM; the swap and the bond are linked for hedge accounting and the unwind value is a dealer quote at the current basis.
The basis: the cross-currency basis is the premium or discount for swapping one currency into another beyond the interest differential; EUR/USD has been negative for most of the past decade (USD costs more), which is part of the hedged return of a EUR bond for a USD fund.
Gilts, Bilateral Settlement and Cleared at LCH Ltd
A bond fund buys gilts by RFQ to several dealers at once and settles through its custodian on CREST, either bilaterally against the dealer (B) or through LCH Ltd under the dealer’s sponsorship (C), which the dealers already use for their own trades. The custodian collects the coupons and the position is the fund’s duration and its liquidity reserve.
Worked example, illustrative:fund buys GBP 150,000,000 10-year noteoffers 99.578 to 99.594 from 5 dealersdone 99.578, 4.302%, T+1B DVP on CREST, risk on the dealer for a dayC sponsored into LCH Ltd, netted, guaranteedcoupon 4.25% semi-annual through the Bank of England

Execution is a platform RFQ in seconds. Settlement is where the routes split: bilateral DVP through the custodian, or submission to LCH Ltd by the sponsoring dealer with net settlement and the CCP guarantee. The fund’s own work is the allocation, the instruction and the reconciliation; the DMO itself is the simplest bond the fund holds.
United Kingdom: gilts are bought by RFQ on Tradeweb or Bloomberg from the gilt-edged market makers and settle at CREST on T+1 (gilts already settle T+1); the dealers clear their trades at LCH Ltd RepoClear, and a fund can be sponsored into the CCP; the DMO runs the auctions and the syndications, and the Bank of England’s portfolio runs down under its sales program.
Execution: most buy-side gilt trading is RFQ on Tradeweb and Bloomberg to the primary dealers (the gilt-edged market makers), with all-to-all and streaming protocols growing; blocks go by voice; the fund’s TCA compares the fill to the composite price at the time.
Clearing in the UK: gilt repo and cash trades clear at LCH Ltd RepoClear, with the dealers as clearing members; a fund clears through a clearing member or as a sponsored member under LCH’s sponsored clearing at LCH Ltd; there is no clearing mandate for cash gilts or repo, but the banks’ balance sheet costs push most of the repo there.
Settlement: the fund’s gilts sit at its custodian, which holds them in CREST directly or through a sub-custodian; bilateral trades settle DVP on CREST, each with settlement risk on the dealer for the day; sponsored trades net at LCH Ltd and settle through the sponsor’s netting.
Uses of the position beyond duration: eligible collateral for cleared and bilateral margin (posted through the custodian), lendable through the agent lender, financeable in repo, and the first thing sold to meet redemptions.
Corporate Bonds on an Electronic Platform, Dealer RFQ and All-to-All
A credit fund buys a corporate bond either by RFQ to several dealers on MarketAxess or Tradeweb (R) or anonymously through all-to-all trading where another investor can be the other side (A). The trade settles DVP at CREST through the custodian, the coupons and corporate actions flow back through CREST, and the vendor’s evaluated price sets the NAV. The order starts and ends with the fund’s issuer limits and liquidity rules.
Worked example, illustrative:fund buys GBP 10,000,000 BBB 7-yearR, offers +137 to +142 bp; done at +137, 101.42A, response +136 bp from another manager, anonymoussettlement T+2 DVP at CREST through the custodiancoupons semi-annual through CRESTNAV evaluated price at the close; 22e-4 liquidity bucket

Electronic trading made the credit order a platform workflow: pre-trade composite, RFQ or all-to-all, straight-through fill to the OMS, CTM confirmation, CREST settlement. The dealer is one of several responders and sometimes not the counterparty at all. What stays manual is the credit view, the corporate actions and the chasing of fails.
United Kingdom: sterling corporate bonds settle at the ICSDs or at CREST, bought by RFQ on MarketAxess, Tradeweb and Bloomberg or by voice from the banks; the dealer publishes the trade through an APA under the FCA’s bond transparency regime (reformed in December 2025) and both sides report the transaction to the FCA; the bond consolidated tape is the first UK tape.
Electronic trading: about half of US investment grade volume trades electronically, led by MarketAxess and Tradeweb RFQ, Open Trading all-to-all, portfolio trading (a basket of up to hundreds of bonds priced as one trade by a dealer, often against an ETF) and algorithmic responses from the dealers for small sizes; high yield is lower but rising.
Pre-trade data: the APA prints (real time, with size caps), composite prices (MarketAxess CP+, Bloomberg BVAL, ICE), dealer axes and runs sent on Bloomberg and Neptune, and the ETF’s implied prices; the fund’s TCA measures each fill against the composite at the time and the dealers’ hit rates.
Settlement at CREST is T+2 since May 2024; CTM matching on trade date is what the FCA’s same-day matching rule expects; the custodian is the CREST participant and the fund’s operations chase fails with the broker; a bond bought on Open Trading settles against the platform’s investment firm.
the COLL liquidity rules: an open-end fund classifies every holding into four liquidity buckets, holds a highly liquid investment minimum and caps illiquid holdings at 15%; corporate bonds move between buckets with market conditions and the vendor’s liquidity scores; the classification is reported in the UK UCITS reporting to the FCA.
Fixed Income›New Issue
Participating in a Bond New Issue
A manager’s credit funds place an order into the syndicate’s book for a new bond, receive an allocation at pricing that is usually a fraction of the order, and settle the bonds at the closing several days later. The manager allocates its share across its funds under its own policy. Nothing is traded on a platform: the book runs on the syndicate’s platform and the sales desks, and the fund’s relationship with the issuer’s banks sets what it receives.
Worked example, illustrative:deal GBP 1.5 billion 10-year, talk +150, launched +125order GBP 60,000,000 at +140 limitallocation GBP 18,000,000 (30%); book 4x coveredpricing 5.35% coupon, 99.85settlement T+5 closing, DVP at CRESTbreak tightened to +118 bp

Jump to13 steps, hover or click any of them
The order is a limit and a size, the allocation is the syndicate’s decision, and the manager’s own allocation among its funds is a compliance process with an audit trail. Settlement waits for the closing, so the fund carries the bond as a pending trade for a week while it already trades in the grey market.
United Kingdom: the corporate new issue is a sterling Eurobond led by the banks’ syndicate desks under a prospectus approved by the FCA or the wholesale exemption (£100,000 denominations, qualified investors), priced in a day from the initial price talk, allocated under the FCA’s allocation rules and settled at the ICSDs; the POATRs replaced the Prospectus Regulation in January 2026.
Allocation by the syndicate: the leads allocate under the issuer’s guidance, favoring large holders, early and firm orders, and accounts that keep bonds; inflated orders and flipping are tracked; the fund’s new issue hit rate is a performance input for a credit fund, since new issues come with a concession to secondary levels.
Allocation within the manager: an allocation policy approved by compliance, usually pro rata to the orders with rounding rules, documented trade by trade; the FCA’s examination priorities list new issue allocation among the conflicts it tests, since it can favor one client over another.
Platforms: Ipreo (now part of S&P) and DirectBooks carry announcements, orders and allocations between syndicates and managers; the manager’s OMS imports the terms; security setup from the prospectus on announcement day is an operations task the trade cannot wait for.
Settlement: new issues close T+3 to T+5 (the time to deliver the final documents) and settle DVP at CREST on the closing date; the bond trades in the grey market from pricing and those trades settle on the closing date too; equities IPOs follow a similar pattern (see Equities, IPO).
High Yield Bonds and a Distressed Position Through a Restructuring
A high yield fund buys a single-B bond by RFQ or by voice from the dealers that hold it (H). A distressed fund buys defaulted notes at a deep discount, joins the creditor group, goes restricted on the name and receives new equity and new notes when the company’s plan is confirmed (D). Both settle at DTC through the custodian; the distressed position is valued by the manager’s fair value process and sits in the illiquid bucket.
Worked example, illustrative:H, fund buys USD 8,000,000 B+ 8-year at 96.50, 7.65%D, fund buys USD 25,000,000 face at 38, flatD, restricted joins the creditor group under an NDAexchange 80% of the new equity plus USD 10 of new notes per 100 face, through DTCvaluation H vendor price; D fair value committee under 2a-5

High yield is a less liquid version of the corporate bond flow, with more voice and more fails. Distressed changes the role of the fund: it becomes a negotiating creditor, its trading is restricted by what it learns, and the position turns into other securities through a corporate action. The valuation moves from the vendor to the manager’s own committee.
United Kingdom: the sterling and European high yield market is a Eurobond market settled at the ICSDs, with the same bookbuild and secondary mechanics, and a restructuring runs under a restructuring plan (Part 26A, with cross-class cram-down) or a scheme of arrangement rather than Chapter 11; the fund also holds US high yield through US dealers, which the diagram shows.
High yield for a fund: issuer and sector limits are tighter, the liquidity classification matters (much of the market is in the less liquid bucket), the call schedule drives the yield to worst, and the ETF (HYG, JNK) is both a liquidity tool and a pricing reference; portfolio trades against ETF creation baskets are a growing execution route.
Distressed for a fund: the restricted list (material non-public information from the creditor group), the fair value process (Rule 2a-5 makes the board or the adviser as valuation designee responsible, with a committee and documented inputs), the 15% illiquid cap for open-end funds, and the operational handling of plan exchanges, claims and new unlisted securities; most distressed investing sits in closed-end funds, interval funds and private vehicles for these reasons.
Settlement: defaulted bonds still settle at DTC as securities; bank debt and trade claims settle by assignment through the agent and take weeks (see Loans); a plan exchange is a mandatory corporate action the custodian processes with instructions from the manager for any elections.
CDS interaction: a fund holding CDS protection on the name goes through the ISDA credit event auction at the same time (see CDS); the bonds it holds can be delivered into the auction or kept for the restructuring.
Housing Association and Agency Bonds for a Managed Account Program
A sub-sovereign SMA program builds ladders for thousands of individual accounts, each with its own custodian and tax preferences. The desk buys from dealer offerings and RFQs on the platforms, aggregates across accounts into round lots, and allocates under a policy; the trades settle at CREST into each client’s own custodian through daily trade files. Coupons are public sector and calls and refundings are a constant corporate action load.
Worked example, illustrative:program 20,000 accounts; a new GBP 2,000,000 account needs 10 rungstrade GBP 500,000 of a 2034 regional bond at 3.05%, split across 3 accountstax-equivalent about 5.15% for the clientreporting the APA within 15 minutes; visible on the FCA registersettlement T+2 DVP at CREST to each account’s custodianoperations trade files to a dozen custodians daily

The product is the same bond flow as corporates with two differences: the client is an individual with a tax profile, and the account is at the client’s custodian, not the manager’s. The desk’s skill is aggregation and allocation across thousands of small accounts; operations is files and reconciliations to many custodians.
United Kingdom: there is no municipal bond market (local authorities borrow from the Public Works Loan Board); the housing associations, Transport for London, the universities and the supranationals and agencies issuing in sterling (the EIB, KfW, the World Bank) are the government-related sterling issuers bought by RFQ and laddered; there is no tax exemption.
The sub-sovereign bond SMA market: over GBP 1 trillion of separately managed accounts run by the large bond managers for private bank and adviser firm clients, on model ladders and active strategies; the client owns the bonds directly in an account at the sponsor’s custodian, which gives tax-lot control and state selection a fund cannot offer.
Execution: dealers post offerings on Bloomberg, MarketAxess and Tradeweb; the desk aggregates buy lists across accounts and trades round lots where possible; odd lots cost more; the APA and the FCA register give a 15-minute public tape that the desk and the regulators use for best execution reviews.
Operations at scale: thousands of custodians and sponsor platforms with their own file formats, SSIs, settlement cut-offs and corporate action interfaces; the manager’s reconciliation and trade file factory is the core system of an SMA business, together with the model and rebalancing engine.
Tax: the interest is exempt from federal tax and from state tax in the issuer’s state; the client’s tax rate sets the taxable equivalent yield; tax-loss harvesting across the ladder is a service the program sells; de minimis and market discount rules affect which discounted bonds the desk buys for an individual.
Credit Default Swaps, Cleared Index and Bilateral Single Name
A credit fund hedges with CDS in two forms. The index (CDX) trades on an MTF or OTF and clears at ICE through the fund’s clearing broker, with initial margin and daily variation margin like a cleared swap (I). A single name trades bilaterally under the ISDA with variation margin under the CSA, and pays out through the ISDA auction if the issuer defaults (S). Both are confirmed on MarkitSERV and live in the DTCC Trade Information Warehouse, which runs the coupons and the credit events.
Worked example, illustrative:I, fund buys protection on USD 50,000,000 CDX HY at 104.12I, IM about USD 2,500,000 at the clearing brokerI, coupon 500 bp quarterly through the clearing brokerS, fund buys USD 10,000,000 at 285 bp; upfront USD 790,000S, credit event recovery 35: USD 6,500,000 received through the TIWvaluation Markit and the CCP; the COLL derivatives rules VaR

The cleared index runs through the clearing broker and the CCP like a cleared rate swap; the single name runs through the dealer and the CSA like any bilateral derivative. The Trade Information Warehouse sits under both and turns a default into a cash payment without any instruction from the fund.
United Kingdom: the iTraxx indices clear at ICE Clear Credit or LCH SA CDSClear under the UK EMIR clearing obligation through a clearing broker, and the single names are bilateral under the ISDA; the COLL derivatives rules cap the counterparty exposure; both sides report under UK EMIR.
What funds use CDS for: hedging credit beta with the indices (CDX IG and HY, iTraxx) rather than selling bonds, hedging a single issuer the fund holds but cannot sell, and taking credit exposure synthetically where the bond is scarce (selling protection); the COLL derivatives rules counts the notional in the derivatives exposure and the VaR.
Clearing: index CDS is mandated for MTF trading and clearing at ICE Clear Credit (and LCH CDSClear); the fund clears through its clearing broker under the same addendum as rate swaps; single names clear voluntarily and most stay bilateral; the roll to a new index series every six months is a trading decision with its own cost.
The Trade Information Warehouse: DTCC’s golden record for CDS; it calculates the quarterly coupons (IMM dates, 20 March, June, September, December) and settles them through CLS, and it runs the credit event settlement after the ISDA determinations committee and the auction.
Credit events: the determinations committee rules, the auction sets the recovery, and protection pays par minus recovery in cash; the fund holding the bonds has a choice between delivering them into the auction (physical settlement request) and keeping them for the restructuring (see High Yield and Distressed).
A loan fund buys a term loan from a dealer by voice, settles it weeks later by assignment on the agent bank’s register through ClearPar, and holds it as a position the custodian books from the agent’s notices. Interest, amortization, repricings and amendments all arrive through the agent. The flow is documents and consents rather than depository settlement, and that is the reason loans sit in the less liquid bucket.
Worked example, illustrative:fund buys USD 15,000,000 term loan B at 99.25terms SOFR plus 375 bp, floor 0.50%, 1% amortizationsettlement T+7 target, T+12 actual; delayed compensationdocuments LSTA confirmation, assignment agreement, agent and borrower consentincome through the agent at each contract periodvaluation dealer-quote composite; CLO trustee tests

The order and the trade look like a bond; everything after does not. There is no depository: the agent’s register is the ownership record, settlement waits for signatures and consents, and the custodian books the loan from notices. A loan operations team that reads agent notices and keys in resets is a buy-side function with no equivalent in bonds.
United Kingdom: UK and European leveraged loans are documented under the LMA and settle by assignment through the agent banks, with ClearPar for the US side; a loan fund in the UK is an AIF or an LTAF; the diagram keeps the US settlement.
Buyers of leveraged loans: CLOs (two thirds of the market, run by asset managers as collateral managers under an indenture with coverage and quality tests), loan mutual funds and ETFs, and private credit funds; each has its own constraints, and the CLO’s tests are rerun on every trade.
Settlement: loans settle by assignment on the agent’s register (par trades) or by participation when assignment is not possible; the LSTA’s T+7 target is missed on average by a week, delayed compensation shifts the economics to the target date, and the LSTA and ClearPar push for faster settlement; a loan ETF carries a cash and TRS buffer for this.
Operations: loan operations teams process agent notices (resets, paydowns, interest, amendments), reconcile positions to the agents, maintain the facility data in the security master (contracts, rates, floors, amortization), and vote on amendments; vendors (ClearPar, Virtus, WSO, Black Mountain) and the custodian’s loan servicing team support it.
Information: the fund can elect to be public-side (no borrower private information, can trade bonds and equity of the issuer) or private-side (receives projections, restricted on the public securities); most loan managers run a public-side desk with a wall to any private-side team.
TBA Mortgages for a Bond Fund, Rolls and Delivery (US Market)
A bond fund gets its mortgage exposure through TBAs: a forward purchase of agency pools for a settlement month, traded by RFQ and margined daily under the MSFTA. Most months the fund rolls the position into the next month instead of taking delivery; when it does take delivery the dealer notifies the pools 48 hours before settlement and the custodian receives them on Fedwire Securities. From then on the pools pay monthly principal and interest with a changing factor.
Worked example, illustrative:fund buys USD 100,000,000 UMBS 30-year 5.5% for Decemberoffers 99-20 to 99-21; done at 99-20VM 1 point is USD 1,000,000 under the MSFTAroll December to January at a drop of 6/32delivery notified pools, DVP on Fedwire Securities on the retail class datemonthly P&I on the 25th; factor updates

A TBA is a forward with margin, so the fund needs an MSFTA and a collateral process for a cash product. The roll keeps the exposure synthetic month after month; delivery turns the forward into pools and a different operational life of factors and paydowns. The fund is never an MBSD member: the dealer nets, the fund settles with the dealer.
United Kingdom: a UK fund trades US TBAs through US dealers and its depositary’s US network, so the diagram keeps the US infrastructure; UK mortgages fund through covered bonds under the regulated covered bond regime and RMBS under the UK securitisation rules, with no forward market.
Why TBAs: the agency mortgage market trades as forward contracts on a coupon and a month rather than on specific pools; a bond fund tracks the index’s mortgage weight through TBAs and rolls, taking delivery only when the roll is expensive or it wants specified pools; the dollar roll’s drop is a financing rate the fund compares to repo.
Margin: FINRA Rule 4210 (2022) requires dealers to collect variation margin on TBAs and specified pools from counterparties beyond a small exception; the fund signs an MSFTA with each dealer and runs the margin like a CSA; the COLL derivatives rules treats a TBA settling in the standard cycle as a non-derivative, but a roll can bring it into the derivatives exposure.
Settlement: SIFMA’s monthly schedule sets the notification and settlement dates by class (A for 30-year UMBS, B for 15-year, C for GNMA); the dealer, as an MBSD member, nets its TBA activity at FICC; the fund settles the net pools with the dealer on Fedwire Securities through its custodian; good delivery rules set the variance and the pool count.
Specified pools: a fund that wants prepayment protection buys specified pools (low loan balance, geography, seasoning) at a pay-up over TBA, settles them like Treasuries and never rolls them; ABS, CMBS and private-label RMBS settle at DTC and are a different workflow (see ABS and CMBS).
A securitized fund buys an ABS class in a new issue through the syndicate and a CMBS mezzanine tranche from a dealer by voice, after running the deals in Intex. Both settle at CREST as Eurobonds through the custodian. From then on the trustee pays monthly through the waterfall and reports the collateral; the analyst reruns the deal each month and the factor drives the accounting.
Worked example, illustrative:ABS new issue GBP 20,000,000 ordered at +58; allocated GBP 15,000,000 at +55CMBS secondary GBP 10,000,000 BBB- at +400, 88.50settlement closing date T+5 and T+2, DVP at CREST, 144Amonthly trustee distributions and factors through CRESTsurveillance Intex rerun with the trustee reportvaluation vendor plus dealer quotes; the liquidity buckets

The trading is a new issue book or a voice trade; the settlement is a corporate bond; the life is a monthly cycle of trustee reports, factors and cash flow models that agency pools do not need. The securitized desk’s analyst, the security master and the factor reconciliation are the parts the rest of the fund does not have.
United Kingdom: UK ABS (the prime and buy-to-let RMBS master trusts, auto and credit card deals) and the European CLOs 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 for the simple deals; the tranches are Eurobonds settled at the ICSDs; CMBS is a small market.
Securitized products for a fund: covered bonds and RMBS (see TBA) is a core index sector; ABS (auto, credit card, student loan, equipment), CMBS (conduit and single-asset deals), non-agency RMBS and CLO tranches are the credit sectors; most are 144A, so the fund must be a qualified institutional buyer and its prospectus must allow 144A holdings.
Analysis and data: the collateral tape and the deal structure are modeled in Intex or Bloomberg; the trustee report arrives monthly on the trustee’s site and through vendors; the factor, the credit enhancement, delinquencies and losses are the surveillance data; the fund’s security master must carry the model and the payment calendar.
Trading: new issues through the syndicate books; secondary mostly by voice and BWIC lists (a holder puts a list out for bids at a set time, dealers bid, the cover is the second-best bid); the APA disseminates 144A securitized trades with caps; liquidity in mezzanine tranches is episodic.
Operations: CREST settlement like corporates, monthly principal and interest with factor updates (a factor mismatch between the trustee, the custodian and the manager is the most common reconciliation break), and the valuation of thinly traded tranches through the fund’s fair value process.
A fund buys a large position by sending the order from its EMS to a broker’s algorithm, which works it across exchanges and dark pools over the day. Fills stream back, the trade is allocated and matched in CTM on trade date, and settles T+2 at CREST through the custodian. The fund never connects to a venue; the broker, the commission arrangement and the TCA are its execution relationship.
Worked example, illustrative:fund buys 400,000 shares, GBP 34,000,000, 8% of the firm’s terms of businessstrategy VWAP algo, 10% participation capresult GBP 85.12 vs VWAP 85.10: 2 cents of slippagecommission 1.5 cents per share; CSA for researchmatching CTM on trade datesettlement T+2 DVP at CREST; the CCP the CCP’s netting on the broker’s side

The fund’s order becomes thousands of child orders it never sees; what it sees is the average price, the slippage and the commission. Post-trade is a straight line: allocation, CTM, CREST, custodian. The fund’s own decisions are the broker, the algorithm and the participation rate.
United Kingdom: the fund’s orders go to the broker’s algorithms across the London Stock Exchange (SETS), the MTFs (Cboe Europe, Aquis, Turquoise) and the systematic internalisers under COBS best execution and the tick size regime, with no volume cap on the dark pools since 2023; the broker reports the transaction to the FCA; the trades clear at LCH Ltd, Cboe Clear Europe or SIX x-clear (the interoperable CCPs) and settle at CREST on T+2, with stamp duty reserve tax of 0.5% on the purchases.
Execution choices: broker algorithms (VWAP, TWAP, implementation shortfall, liquidity seeking, dark aggregation), direct market access, program trades for baskets, blocks with a sales trader or on a block venue (Liquidnet, the broker’s crossing); the trader’s choice and the broker list are governed by the best execution policy and reviewed by the brokerage committee with TCA.
Commissions: a few cents per share, with a research component under commission sharing arrangements (CSAs) or, for MiFID-affected managers, paid from the manager’s own P&L; soft dollars under the UK MiFID research rules remain the US framework; the broker vote allocates research payments.
Post-trade: allocation and matching in CTM matched under the T+1 code’s allocation and confirmation practices is the FCA’s same-day matching expectation under T+2 (since May 2024); the custodian settles DVP at CREST against the broker, whose own side is netted in the CCP’s netting; the fund’s operations monitor the fail queue (the exchange’s and the CCP’s buy-in rules fall on the broker).
Reporting on the fund: the quarterly holdings disclosure (none in the UK) quarterly holdings for managers over GBP 100 million, DTR 5 notifications at 3% for positions over 5% of an issuer, the LEI (no large trader identification in the UK) for large traders, and the broker’s transaction reporting reporting of every order; short sales bring Rule the net short position reports under the UK short selling rules reporting of short positions.
Equities›Program Trade
Program Trade for an Index Rebalance
An index fund trades a basket of hundreds of names at the closing price on the day the index changes. The basket goes to a broker’s program desk, either as a guaranteed close trade (the broker guarantees the closing price on every name for a fee) or as an agency trade worked into the closing auctions. Five hundred fills come back at 17:30, are matched in CTM and settle T+2 at CREST through the custodian.
Worked example, illustrative:rebalance 23 changes across 500 names; GBP 180,000,000 two-wayexecution guaranteed close at 2 cents per share, or agency MOCfills every name at the official closepost-trade 500 CTM matches; 500 instructions to the custodiantracking zero rebalance tracking error by construction

A program trade is one order with five hundred lines and a single benchmark: the close. The broker carries the auction risk, the fund carries the file and the reconciliation. The same flow runs for cash flows into and out of an index fund every day, with a smaller basket.
United Kingdom: the program trade follows the FTSE quarterly reviews and the MSCI rebalances, executed by the banks’ program desks across the venues with the London Stock Exchange’s closing auction; the trades clear at the interoperable CCPs.
Program trading: baskets traded as one order by the broker’s program desk, on an agency basis (worked, commissions) or as principal (guaranteed VWAP or close, a fee or a spread); index funds, ETFs, transition managers and quant funds are the users; the broker hedges a principal basket against futures and the auction imbalance.
Index events: S&P, Russell (the June reconstitution is the largest equity trading day of the year), MSCI and FTSE rebalances concentrate flow in the closing auction; the index provider’s files arrive days ahead; the index team computes the basket from the fund’s cash and the new weights.
Operations: hundreds of trades in one file; CTM matching and custodian instructions by file; fails on names leaving the index are the main exception; a fund with many portfolios tracking the same index trades a block and allocates by the portfolios’ weights.
Transition management: when a plan moves a mandate between managers, a transition manager trades the legacy portfolio into the target one with the same program machinery, reporting the implementation shortfall to the plan; the custodian moves positions in kind where the two portfolios overlap (free of payment transfers).
A fund sells a position that is several days of volume in one trade, to a broker that bids for the whole block as principal and takes the risk of working out of it. The trader compares the broker’s discount with the expected cost of an algorithm over several days and with a natural buyer on a block venue. The trade prints as one block, settles T+2 through the custodian, and the shares the fund had on loan are recalled before it.
Worked example, illustrative:fund sells 2,500,000 shares, GBP 120,000,000, 3 days of volumerisk bid GBP 47.60 vs last 48.00: 0.8% discountalternative a 3-day algo at about 0.5% plus driftdone as principal at 15:05; risk transferredsettlement T+2 DVP at CREST; loans recalled first

A block converts days of market risk into a discount paid in a minute. The decision is the trader’s, documented against the alternatives for best execution; the post-trade is the same as any equity trade, with one extra step: the recall of shares on loan, which a fund that lends must plan before it sells.
United Kingdom: the block is crossed under the large-in-scale waiver on a venue or a block MTF (Liquidnet, Cboe BIDS, Turquoise Plato), or bought by the bank as principal; UK MAR governs the handling of the inquiry and the bank’s risk position is under the PRA’s market risk rules.
Block routes: a risk bid from a broker’s block desk (capital commitment), a natural cross through a sales trader or a block venue (Liquidnet, Luminex, the brokers’ conditional order types), or an agency algorithm over days; the trader’s choice and its documentation are the best execution record.
Information: a block inquiry leaks; the trader limits the brokers shown and the time between inquiry and trade; the broker’s own trading ahead of a client block is surveilled (front running); Regulation FD and the fund’s own insider policy limit what the PM can act on.
Securities lending interaction: a fund that lends must recall the shares before it sells (T+2 settlement leaves one day for the return); the lending agent’s recall process and the fund’s OMS link (shares on loan flagged as unavailable) are what prevent a fail on a sale.
Tax and distributions: a US mutual fund distributes realized capital gains to its shareholders each year; large sales late in the year are checked against the distribution estimate; ETFs avoid most of this through in-kind redemptions (see ETFs).
An equity fund keeps new subscription cash exposed to the market by buying index futures through an executing broker, given up to its clearing broker, and buys the actual stocks later in one program trade. The clearing broker holds the margin, the custodian wires the daily variation, and the unwind can be done as an exchange for physical with a dealer. The flow is the gilt futures flow with an equity index.
Worked example, illustrative:cash to equitize GBP 50,000,000 of subscriptionsfutures 220 ES at 5,210.25, GBP 57.3m notionalIM about GBP 12,000 per contract, GBP 2,640,000VM 1% is GBP 573,000 a dayunwind sell futures and buy the basket at the close, or an EFPthe COLL derivatives rules usually within the limited user exemption

Equitization is the most common futures use in a long-only fund: cash flows, dividends and redemptions are all managed with a few contracts rather than hundreds of stock trades. The executing broker, the clearing broker, the margin and the custodian are the same chain as any futures position; the program trade at the end is the same as an index rebalance.
United Kingdom: the FTSE 100 and FTSE 250 futures trade on ICE Futures Europe and clear at ICE Clear Europe through the fund’s clearing broker; the COLL global exposure rules govern the overlay.
Uses: equitizing cash (subscriptions, dividends, a cash buffer for redemptions), tactical asset allocation overlays across equity, bond and currency futures, transition management, and hedging a long portfolio; the cost is the futures basis (the implied financing rate, which trades rich when dealers’ balance sheets are tight) and the roll.
EFPs and basis trades: an exchange for physical swaps a futures position for the underlying basket with a dealer at a negotiated basis, in one trade reported to ICE Futures Europe; it avoids trading the basket in the market and is how large funds move between futures and stocks.
Clearing and margin: the same clearing broker, give-up, SPAN margin, 4d(a) segregation and daily variation flow as gilt futures (see Rates, Gilt Futures); equity index futures margin is higher and the variation larger in a sell-off, which the fund’s cash forecast must cover.
the COLL derivatives rules: a fund whose derivatives exposure is under 10% of net assets is a limited derivatives user and needs no VaR test, only policies; equitization overlays and currency hedges usually fit; a fund above the threshold needs the full program with a derivatives risk manager.
An equity income fund sells one-month calls on part of its holdings every month through an options broker, cleared at ICE Clear Europe with the shares as cover. The premium arrives T+2; at expiry the in-the-money calls are assigned and the custodian delivers the shares at the strike, the rest expire. The shares are locked while the calls are open, which the OMS and the lending program must know.
Worked example, illustrative:overlay calls on 20% of holdings, 5% out of the money, monthlytrade 2,000 December 90 calls on stock X at GBP 1.86: GBP 372,000premium GBP 4,100,000 across 16 lines, T+2cover shares at the custodian under an escrow receiptexpiry stock at 93: assigned, 200,000 shares delivered at 90yield about 0.5% a month on the covered portion

Listed options for a fund run through a broker and a single clearing house, like futures, with one twist: the shares must cover the written calls, so the custodian certifies them and the fund cannot lend or sell them. Expiry is where the work is: assignments become stock deliveries the custodian settles the next day.
United Kingdom: options on UK names and on the FTSE 100 trade on ICE Futures Europe and clear at ICE Clear Europe; the covered call overlay runs within the COLL efficient portfolio management rules.
Options for funds: covered call and put-write income strategies, protective puts and collars on a portfolio, index options (FTSE 100, cash settled, European) for hedging, and the defined outcome ETFs built from FLEX options; each is the COLL derivatives rules exposure and a cover or margin question.
Clearing: all US listed options clear at ICE Clear Europe through the broker as clearing member; written options require margin unless covered; a fund covers calls with the shares (escrow receipt from the custodian) and puts with cash or gilts; the broker’s margin rules and the fund’s custody arrangement must agree.
Expiry and assignment: American-style equity options can be assigned any day, with early assignment likely before a dividend; ICE Clear Europe assigns by random allocation to clearing members and the broker to accounts; assignments settle as stock trades T+2; index options settle in cash at the opening or closing index level.
Execution: options trade on ICE Futures Europe under one clearing house; brokers route to the best quote and use auctions for size; the fund’s TCA on options compares the fill to the mid and the implied volatility; large lines can be negotiated with a market maker and crossed on the floor.
ETFs as an Investor, Secondary Market and Creation
A fund buys an ETF for quick exposure to a sector, either in the secondary market through a broker like any share (S) or, for size, through an authorized participant that creates new shares at NAV (C). The ETF settles at CREST like a stock, pays through CREST, and is priced at its exchange close; the fund looks through to its holdings for its own limits and reports it under the fund-of-funds rules.
Worked example, illustrative:fund buys GBP 40,000,000 of a high yield ETF for a monthS 520,000 shares at 77.04, 3 cents over iNAVC creation through an AP at NAV plus fee and spreadsettlement T+2 DVP at CREST; creation through the CCPrules COLL fund-of-funds limits; look-throughexit secondary sale or in-kind redemption

Jump to15 steps, hover or click any of them
For a fund an ETF is a share that happens to be a portfolio: the execution, matching and settlement are those of any equity, and the creation route is a way to get size at NAV through an AP. What the ETF adds is the look-through, the fund-of-funds limits and the premium or discount to NAV as a cost.
United Kingdom: the ETFs are Irish UCITS ETFs created and redeemed through the authorised participants at the transfer agent, settled through the ICSD structure or CREST depositary interests; the same ETF trades on the London Stock Exchange and the MTFs, and most volume is OTC through the market makers on the RFQ platforms, reported through APAs; the consolidated tape will change that picture.
Why a fund buys ETFs: cash equitization in bonds (where futures are a poor proxy), tactical sector or country exposure, a liquidity sleeve for redemptions in a less liquid fund, and model portfolios built entirely from ETFs; the costs are the ETF’s expense ratio, the premium or discount to NAV and the bid-ask spread.
Creation and redemption: authorized participants (large investment firms) exchange the basket for shares at NAV through the ETF’s distributor and the CCP; a fund that needs size can trade with an AP at NAV plus a spread rather than in the secondary market; in-kind redemption delivers the underlying securities, which a bond fund may want.
COLL lets a UCITS put up to 20% in one fund and 30% in non-UCITS funds, with a look-through to the underlying for the risk limits; ETFs are the main case; the fund’s look-through to the ETF’s holdings feeds its own concentration and liquidity rules.
Operations: an ETF settles at CREST T+2 like a share; the fund’s security master carries it as an equity with a look-through file from the sponsor’s daily holdings; pricing is the exchange close, so an ETF of foreign or illiquid assets carries a premium or discount the fund’s NAV reflects.
Total Return Swaps for a Hedge Fund Through Its Prime Broker
A hedge fund takes a short and a leveraged long through total return swaps with its prime broker rather than borrowing and buying stock. The PB executes the hedge in the market and passes the stock return plus or minus a financing spread; the fund posts margin from its PB account, receives daily or monthly resets, and never holds the shares. The swaps are derivatives reported under UK EMIR the PB reports, and the fund’s exposure to the PB is a counterparty risk it manages with a second prime and a custodian.
Worked example, illustrative:short GBP 30,000,000 of a European stock; pays the return, receives SONIA minus 40 bplong GBP 20,000,000 of a US name; receives the return, pays SONIA plus 60 bpmargin about 15% of gross, GBP 7,500,000 at the PBresets daily or monthly; dividends pass throughreporting PB to the trade repository; the fund in the Annex IV report under UK AIFMDunwind after three months; margin released

Jump to14 steps, hover or click any of them
A swap turns the prime broker into the fund’s whole post-trade chain: execution, borrow, custody of the hedge, margin, resets and reporting all sit with the PB. The fund’s operational work is the confirmation, the margin and the reconciliation to the PB’s statement; its risk is the PB itself.
United Kingdom: the total return swap is with the prime broker under the ISDA, reported under UK EMIR and, where it is a securities financing transaction in substance, under UK SFTR; a UK hedge fund is an AIF managed by an FCA-authorised AIFM, and the swap avoids the stamp duty a purchase would carry.
Hedge funds and prime brokers: a hedge fund holds most of its assets at one or two prime brokers under a prime brokerage agreement that gives the PB a lien and the right to rehypothecate; swaps, margin lending, stock borrow and short sales all run on the PB’s platform; the fund’s counterparty risk to the PB (2008, Lehman) is why the largest funds use several primes and move unencumbered assets to a custodian.
Why swaps: leverage on the PB’s balance sheet, shorts without the fund doing the locate and the borrow, access to markets the fund is not set up for, and in some cases a different tax or disclosure treatment; the cost is the financing spread and the dependence on the PB; the Archegos collapse (2021) was family office total return swaps across several primes with no view of the whole.
Reporting: equity TRS are derivatives reported under UK EMIR under UK EMIR, reported by the dealer to the trade repository; the FCA’s Rule 10B-1 (position reporting for large security-based swap positions) and the quarterly holdings disclosure (none in the UK) and a major holdings notification treatment of swap exposure are the current regulatory edge; the Annex IV report under UK AIFMD reports a large adviser’s exposures, leverage and counterparties.
Operations: confirmations under the ISDA equity derivatives definitions (2002 or 2011), daily resets or monthly, the PB’s margin on a portfolio basis across swaps, stock borrow and cash positions, and the administrator’s reconciliation to the PB statement for the monthly NAV; the hedge fund’s treasury function manages the margin and the financing across primes.
Equities›IPO
Participating in an IPO
A manager’s funds indicate interest in an IPO through the syndicate’s book, receive an allocation that is a fraction of their demand when the deal prices, and settle the shares at the closing after the first trading day. The manager allocates its shares across its funds under a policy the FCA examines. Nothing is traded on a venue until the first day; the allocation is a relationship outcome and the flipping decision a policy one.
Worked example, illustrative:deal GBP 1.2 billion, range 28 to 32, priced at 34indication GBP 60,000,000 at the rangeallocation 400,000 shares, GBP 13,600,000, 23% of demandfirst day opens at 41closing DVP at CREST, T+2 after the first trading daypolicy allocation across funds documented and tested

Jump to12 steps, hover or click any of them
The IPO flow is the bond new issue flow with a public first day in the middle: the indication, the pricing, the syndicate allocation and the manager’s internal allocation all happen before the shares exist in CREST. The fund’s operations set the security up from the prospectus and carry a pending trade until the closing.
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 (the single commercial companies category) or admitted to AIM with a nominated adviser, settled at CREST; the allocation follows the FCA’s allocation rules (COBS 11.3); follow-ons are accelerated bookbuilds.
Allocation: the issuer and the leads allocate to accounts they expect to hold, with hedge funds and fast money allocated less; the manager’s IPO hit rate and its treatment by the syndicates depend on its roadshow participation, its indication quality and its flipping record; the FCA’s rules and 5131 restrict allocations to industry insiders and spinning.
Internal allocation: an IPO allocation policy (pro rata to demand, with rounding and minimums, documented before pricing) is required under the adviser’s compliance program; the FCA examines whether hot IPOs were allocated to favored funds or accounts; a fund that cannot buy IPOs (a value mandate) must not be used to park them.
Mechanics: indications through the syndicate’s platform or the sales desk, pricing the evening before, the first trade in the opening auction of the listing exchange (a designated market maker on the London Stock Exchange, a cross on the London Stock Exchange), and the closing DVP at CREST on T+2 after the first day; the lead’s stabilization bid and the greenshoe operate in the first 30 days.
Follow-ons and blocks: a secondary offering by an issuer or a selling shareholder runs the same book and allocation flow, overnight; a block trade by a selling shareholder is bought by a bank and reoffered to funds in an hour; both are confirmed and settled like any share (T+2), without a closing period.
Commodity Futures for an Index Fund, the Monthly Roll
A commodity index fund holds its exposure in futures on two dozen contracts with the rest of its assets in Treasury bills as collateral. Every month it rolls each contract forward with the index, trading calendar spreads at the settlement price through an executing broker, given up to its clearing brokers. The clearing brokers hold the margin in bills, the custodian moves the daily variation, and the fund watches position limits across every contract.
Worked example, illustrative:fund USD 2 billion tracking the Bloomberg Commodity Index, 24 contractstoday’s roll sell 300 Dec WTI, buy 300 Jan, TAS, for 5 daysfills 78.12 / 77.85: backwardation, positive rollIM about USD 160,000,000 in bills at the clearing brokersVM a 1.5% day is USD 30,000,000limits FCA and exchange limits checked daily

Jump to14 steps, hover or click any of them
The fund is two portfolios: futures that carry the exposure and bills that carry the money. The roll is the recurring trade, executed at the settlement price to match the index; the margin and the variation are the recurring operations; the position limits are the recurring compliance check. Nothing physical ever appears.
United Kingdom: commodity futures are a global market (ICE Futures Europe for Brent, gasoil and UK gas, the LME for metals, the CME) through the fund’s clearing broker; a UK UCITS cannot hold commodity derivatives directly, so the index fund is an AIF or holds them through an index swap or exchange-traded commodities.
Commodity exposure for funds: index funds and ETFs on the Bloomberg Commodity Index and the S&P GSCI, active commodity funds, and multi-asset funds with a commodity sleeve; all hold futures (or swaps on the index with a dealer) and collateral; physical commodities are held only by precious metals trusts (see Gold).
The roll: a futures index rolls its contracts on a published schedule; the fund trades TAS or settlement-priced spreads to match; the roll yield (positive in backwardation, negative in contango) is a large part of the return; enhanced strategies roll to other months to reduce the cost; the index roll days attract front-running by other traders.
Position limits: FCA federal limits on 25 core contracts (agriculture, energy, metals) and exchange limits on the rest; passive index funds hold exemptions in some cases; the fund’s compliance engine checks limits per contract, per month and across all accounts and funds the manager controls (aggregation), which is the hard part.
Structure and tax: a US mutual fund or ETF holding commodity futures earns non-qualifying income under COLL’s tax rules, so most hold the futures in a Cayman subsidiary (up to 25% of assets) or qualify as a commodity pool; the collateral (bills) is the fund’s income and its liquidity for margin; two clearing brokers are standard for continuity.
A gold ETF or a precious metals fund buys gold from an LBMA dealer, unallocated at first, and has it allocated into specific bars in its account at a London vault against payment. The fund owns the bars, which the vault lists by serial number and audits; the holding earns nothing and costs a storage fee, and the NAV is the ounces times the LBMA price. There is no exchange, no clearing house and no depository.
Worked example, illustrative:fund buys 9,300 ounces loco London at USD 2,415.10value USD 22,460,430 on T+2allocation 23 bars, 9,298.7 ounces, listed by serial numbercustody a London vault; sub-custodians disclosedcost a storage fee in basis points, paid in goldNAV ounces times the LBMA Gold Price PM

Gold trades like FX (spot, loco London, T+2, bilateral with a dealer) and settles like a physical delivery: specific bars moved on a vault’s books against a wire. The fund’s records are a bar list, not a depository position, and its reconciliation is a count. A futures-based gold fund would run the commodity futures flow instead.
United Kingdom: physical gold products are exchange-traded commodities listed on the London Stock Exchange rather than funds, since a UCITS cannot hold physical gold; the metal sits in a London vault, allocated under the LBMA’s rules and audited.
Physical gold funds: the large gold ETFs (SPDR Gold Shares, iShares Gold Trust) are grantor trusts holding allocated gold at a London custodian with APs creating and redeeming in gold; precious metals mutual funds hold a mix of metal, futures and mining shares within COLL’s limits; the metal is bought from LBMA dealers at spot or at the LBMA Gold Price auction.
Unallocated and allocated: unallocated gold is a claim on a dealer or bank’s pool (credit risk, no storage fee, the form most trading uses); allocated gold is specific bars in the client’s name (no credit risk, a storage fee, a bar list); funds hold allocated and accept unallocated only in transit; the allocation is a book entry at the vault, not a physical move.
Operations: confirmations by MT600, allocation instructions by MT604, bar lists by weight and fineness (400-ounce London good delivery bars are 350 to 430 ounces, 995 fine or better), monthly vault statements and semi-annual physical counts; sub-custodians (the Bank of England and other LBMA vaults) are a disclosure and a risk item.
Other metals and physical holdings: silver, platinum and palladium trusts run the same way at London and Zurich vaults; funds do not hold oil or grain; a commodity fund that wants physical exposure to base metals can use LME warrants, which are warehouse receipts transferred on LMEsword (see the sell-side Commodities, Base Metals).
Inside the Firm›Front to Back
One Order Through the Firm, Front to Back
The corporate bond purchase of the Fixed Income section, seen from inside the asset manager: who touches the order, in what sequence, in which system. Portfolio management decides, compliance tests, the desk executes, operations confirms and instructs, the custodian settles, the administrator strikes the NAV and fund finance releases it. The OMS is the spine; the IBOR is the firm’s own book; most steps are automatic.

The columns run from the investment decision on the left through the control and operations teams to the outside world on the right. Every arrow is a hand-off between two teams or two systems and the pill names the system. The chain is the same for every product; the product decides the venue, the confirmation platform and the settlement rail.
United Kingdom: the manager is the authorised fund manager of UK UCITS and NURS (an authorised corporate director for the OEICs) or an AIFM, and a MiFID portfolio manager for the mandates, authorised by the FCA with a depositary for every fund; the regulator is the FCA, with the senior managers certified under the SMCR; the custodian is the depositary bank.
Who is who: portfolio management and research make decisions; the trading desk executes and owns best execution; compliance tests before and after and files; investment operations (trade support, settlements, reconciliations, corporate actions, collateral) make the trades real; data and technology run the security master, pricing and the IBOR; the cash team funds the trades; fund finance oversees the administrator and the reporting. Risk sits with compliance as the second line.
Systems: one order management system is the spine of most managers (Aladdin, Charles River, SimCorp Dimension, Bloomberg AIM, Eze), with an EMS for equities and FX, a compliance engine inside or beside it, an IBOR (in the OMS or separate), a data warehouse, and feeds to the custodian and the administrator; the administrator’s accounting system is the accounting book of record (ABOR) and the manager reconciles its IBOR to it daily.
Outsourcing: most managers outsource custody, fund accounting, transfer agency and often middle office (confirmations, settlements, reconciliations) to the custodian banks (BNP Paribas Securities Services, State Street, JPMorgan, Northern Trust, Citi) and the administrators; what stays inside is the decision, the execution, compliance, oversight and the data; the oversight of the providers is itself a function (see Oversight and Vendors).
Controls along the way: pre-trade compliance, the allocation policy, the TCA, the CTM match, the settlement match, the position and cash reconciliation, the NAV review and the post-trade compliance run are the points where an error is caught before it reaches the NAV or a client.
Inside the Firm›Mandate Onboarding
Onboarding a Mandate or Launching a Fund
What happens between a mandate award or a fund approval and the first trade: the IMA or prospectus turned into coded guidelines, accounts at the custodian and every broker and dealer, agreements (ISDA, clearing broker, MSFTA, MRA), the portfolio in the OMS and the IBOR with its rules and risk limits, the funding, the initial investment program, and the start of reporting and regulatory cycles. Weeks of setup, most of it operational.
Who uses what:legal and compliance IMA negotiation, guideline coding in the compliance engine, N-1A and board for a fundoperations custodian accounts and SSIs (ALERT), broker and dealer setups, ISDA, clearing broker, MSFTA and repo agreementsops portfolio setup in the OMS and the IBOR, benchmark, accounting feed, reportingrisk limits in the risk engine, the COLL derivatives rules programfinance performance inception, fee schedule, GIPS composite

Jump to14 steps, hover or click any of them
Onboarding is the mandate’s setup phase and the point where most later operational errors are created: an uncoded guideline, a missing broker setup or a wrong SSI shows up months later as a breach, a fail or a break. The go-live checklist is the control.
United Kingdom: a fund launch needs the FCA’s authorisation of the UCITS, the NURS or the QIS, the prospectus and the KIID or KID, the depositary agreement and the authorised fund manager’s approval; a pension mandate follows the Pensions Act, the Pensions Regulator’s rules, the trustees’ statement of investment principles and the investment consultant’s selection, with the LGPS pools for the local authority schemes.
Documents: the investment management agreement (institutional), the prospectus and statement of additional information (fund), the custody agreement (the client’s or the fund’s), the ISDA with a CSA per dealer, the futures and cleared derivatives agreements with the clearing broker, the MSFTA, the MRA, the securities lending agreement, the prime brokerage agreement for a hedge fund; each must name the account before it can trade that product.
Guideline coding: the IMA’s words become rules in the compliance engine; the hard cases are relative limits (duration within a band of the benchmark), look-through rules (ETFs, funds), ESG exclusions needing a data vendor, and ambiguous terms ("high quality"); the coded rules and the client’s sign-off on their interpretation are kept with the IMA.
Client types and their differences: a registered fund (COLL tests, board, NAV, transfer agent, public filings), an institutional separate account (IMA, the client’s custodian, client reporting, no NAV), a collective investment trust (bank-sponsored, for plans), a UCITS or other offshore fund (a management company, a depositary, a different rule set), and a hedge fund (an offering memorandum, a prime broker, a monthly NAV by the administrator).
Transitions: a new mandate funded in kind from a previous manager uses a transition manager to trade from the legacy portfolio to the target with implementation shortfall reporting; the custodian moves overlapping positions free of payment; terminations run the same way in reverse with a final reconciliation and performance period.
Inside the Firm›Reference Data and Pricing
Reference Data, the Security Master and Pricing
Every order, test, valuation and report in the firm reads from the same reference data: the security master built from vendor terms, the daily prices chosen under the valuation policy, the standing settlement instructions in ALERT, the counterparty master and the index data. The data team maintains it, the valuation function rules on exceptions, and the administrator keeps a parallel copy that must agree with it for the NAV.
Who uses what:security master GoldenSource, Eagle, or the OMS’s own; vendors Bloomberg, ICE, Refinitiv; identifiers ISIN, ISIN, FIGI, LEIpricing evaluated prices, exchange closes, FX fixings, dealer quotes and models; pricing hierarchy, tolerances, the valuation committee (Rule 2a-5)settlement data SSIs in DTCC ALERT, counterparty master, call-back controlsbenchmarks index constituents and returns under licensegovernance owners, golden sources, lineage, quality metrics, data warehouse

Jump to13 steps, hover or click any of them
A security that does not exist in the master cannot be ordered; a price that is wrong is a wrong NAV; an SSI that is wrong is a fail. Reference data is the quiet function the rest of the firm depends on, and the one the administrator duplicates.
United Kingdom: the security master carries the ISINs and SEDOLs with CREST and ICSD settlement details, the LEIs for UK EMIR and UK MiFIR reporting, the venue and instrument reference data (the FCA’s FIRDS) and the fund platforms’ codes; the pricing policy follows the COLL valuation rules.
Systems: the security master is in the OMS for smaller managers and a dedicated platform for larger ones; the pricing engine applies the hierarchy and tolerances; the data warehouse stores positions, prices and transactions for reporting; cloud data platforms (Snowflake and the like) now hold the warehouse; the vendors’ data licenses restrict redistribution and are audited.
Valuation under COLL: the authorised fund manager is responsible for the pricing and the depositary oversees it; the manager’s valuation committee sets the policy, approves pricing sources, reviews exceptions and fair-values what the vendors cannot price; the administrator applies the policy and challenges prices; the board receives quarterly reports; the same process serves the institutional accounts’ IBOR valuations.
SSIs and payment fraud: a changed SSI received by email is the standard fraud attempt; the control is ALERT as the source for custodians’ SSIs, call-back to a known number for any change, and dual approval; the firm’s own SSIs are the same risk for its clients’ custodians.
What goes wrong: a new issue whose terms arrive late, a factor mismatch on a securitized bond, a corporate action that changes the security (a new ISIN after a merger), a stale price in a thin market, a vendor outage at the close; each becomes a NAV error, a breach or a fail if not caught, so the data team sits in operations and not in technology alone.
Inside the Firm›Portfolio Construction
Portfolio Construction, Models and Orders
How an investment decision becomes orders across many accounts: research into a model portfolio, the model against each account’s actual holdings and cash, a rebalance that generates orders per account, pre-trade compliance, and an aggregated block for the desk. Subscriptions and redemptions come in from the transfer agent and the cash team and drive the next day’s orders. Risk, performance and compliance review the result.
Who uses what:research research management system, sell-side research, quant signals, ESG dataportfolio portfolio system or OMS: model portfolios, rebalance engine, drift and cash; risk engine (Aladdin, Barra, Axioma) for the risk budgetorders OMS aggregation across accounts, instructions to the EMSflows transfer agent estimates and finals, cash forecastreview risk engine, performance system, allocation and conflicts reviews

Jump to12 steps, hover or click any of them
A model portfolio is the decision; the accounts are copies with their own constraints; the rebalance engine is the translation; the desk receives one block per security and the accounts receive their share at one price. Cash flows and risk limits are the two external forces on the model every day.
United Kingdom: the compliance checks encode the COLL limits (5/10/40 for a UCITS, the 20% deposit limit, the global exposure, the counterparty limits) or the AIF’s leverage limits and the mandate; the managers are under COBS and the fund rules.
Model-based management: most long-only managers run each strategy as a model portfolio with every fund and separate account tracking it within tolerances; the rebalance engine (in the OMS or the portfolio system) generates the orders and handles exclusions, cash and round lots; SMA programs with thousands of accounts run entirely on this engine (see the Fixed Income section, Municipal Bonds).
Order aggregation and allocation: orders for the same security across accounts are aggregated into a block so that every account gets the same average price; the allocation policy (pro rata, with minimums and rounding) is written, tested by compliance and examined by the FCA; partial fills are allocated by the same rule.
Cash flows: an open-end fund receives net subscriptions or redemptions every day through the transfer agent, which the PM must invest or fund; the cash forecast, the sweep and a futures overlay are the tools; large redemptions in a less liquid fund are the 22e-4 scenario the liquidity program plans for; swing pricing and liquidity fees are the tools in Europe and, since 2023, for US money funds.
The three reviews: risk (is the portfolio within its risk budget and limits), performance (did the decisions add value, by what), compliance (were clients treated fairly in allocation and side by side); each produces a report to the fund board or the client and each can force a trade.
Inside the Firm›Trading and Best Execution
The Trading Desk, Best Execution and Brokers
The desk sits between the portfolio managers’ orders and the brokers, dealers and platforms. It chooses the route under the best execution policy, manages the order through the day in the EMS, and hands the fills to post-trade. Transaction cost analysis measures every fill, the brokerage committee reviews it quarterly, commissions and research payments are allocated under CSAs and the broker vote, and compliance surveils the desk.
Who uses what:desk EMS (FlexTrade, Bloomberg EMSX, Portware, Tradeweb and MarketAxess for bonds, FXall for FX), FIX connectivity, OMS allocationgovernance best execution policy, approved broker list, brokerage committee, TCA (internal or Flow Traders, Abel Noser, BestX)commissions CSAs, the UK MiFID research rules, the broker vote, research payment accounts for MiFID clientsrisk and surveillance counterparty limits, trade surveillance, 17a-7 and 17e-1 reviews, communications retention

Jump to12 steps, hover or click any of them
The desk’s product is a fill and its proof is the TCA. The broker relationship is a setup, a route choice, a connection and a quarterly review; the commission is the one place where the desk’s choice pays for something else (research), so it is governed and reported.
United Kingdom: best execution under COBS, the research paid from the manager’s own account, a research payment account or, since the FCA’s 2024 rules, bundled with execution again under a budget and a disclosure, the broker list and the transaction reports the brokers make; the venue landscape is the London Stock Exchange, the MTFs and the SIs.
Desk organization: a central dealing desk by asset class is the norm for large managers (equities, fixed income, FX and derivatives, sometimes money markets separately), with regional desks following the sun; small managers let the PMs trade; outsourced trading desks (Northern Trust, State Street, Jones Trading and others) serve managers that do not want a desk.
Best execution for an adviser is a fiduciary duty under UK MiFID, documented by a policy, a committee and TCA; for equities the RTS 27 report and RTS 28 reports from brokers and venues feed the venue analysis; for bonds and FX the composite prices and the RFQ records are the evidence; the UK dropped the RTS 27 and 28 reports in 2021 and relies on the firm’s own monitoring.
Commissions and research: US managers pay for research with client commissions under the UK MiFID research rules through CSAs; after MiFID II most global managers pay for research themselves for European clients; the broker vote, the research budget and the CSA administration (often by a vendor) are a compliance process; bond and FX trading has no commission, so research there is paid in hard dollars or bundled in the relationship.
Operational dependencies: the desk needs every broker set up in the EMS, the OMS, CTM and ALERT before it can trade with it; a new fund must be mapped at every broker (see Mandate Onboarding); a broker’s operational failure (missed matching, fails) is part of the quarterly review.
Inside the Firm›Compliance
Compliance, Guidelines and the Code of Ethics
Compliance turns every mandate, prospectus and regulation into coded rules, tests every order before and every account after trading, logs and reports breaches, runs the code of ethics for personal trading, maintains the restricted list, approves cross and affiliated trades, reports to the fund board and the regulator, and oversees the service providers. The compliance engine does the testing; the people do the interpretation, the exceptions and the records.
Who uses what:rules IMA, prospectus, COLL and UK MiFID rules, the Pensions Act and the Pensions Regulator’s rules, UCITS; the rule library and interpretationsengine compliance engine (Charles River, Aladdin, Fundapps, SimCorp, Bloomberg) with pre-trade, post-trade and daily runsethics personal trading system (ComplySci, StarCompliance, MCO), restricted list, information barriersgovernance breach log, board reporting, 38a-1 and 206(4)-7 reviews, FCA exams, service provider oversight

Jump to12 steps, hover or click any of them
Compliance is a rules engine with a records function around it. The rules are only as good as the data they test (see Reference Data), the exceptions are where the judgment is, and the records (breach log, allocation records, exam files) are what the regulator reads.
United Kingdom: the compliance function under SYSC and the fund rules (COLL, FUND), the risk management function, the conflicts policy, the personal account dealing rules, the UK MAR controls, the sustainability labels and disclosures under the FCA’s SDR, the assessment of value, the Consumer Duty and the FCA’s supervision.
Rule families for a US manager: COLL for funds (diversification, concentration, leverage and derivatives under the COLL derivatives rules, liquidity under 22e-4, names under 35d-1, fund of funds under 12d1-4, affiliated transactions under 17a-7, 17d-1 and 17e-1, valuation under 2a-5), UK MiFID for the adviser (fiduciary duty, the compliance program rule 206(4)-7, the code of ethics 204A-1, the CASS rules 206(4)-2, marketing rule 206(4)-1, pay-to-play, books and records 204-2), the Pensions Act and the Pensions Regulator’s rules for plan assets, the CEA and FCA rules for commodity interests, and the IMA for each client.
Pre-trade and post-trade: the pre-trade test prevents active breaches; the post-trade run catches passive ones and the effect of prices and ratings; the cure period and the client reporting terms are in the IMA; the error account and the reimbursement policy handle the losses; the FCA’s exams focus on whether the breach log is complete and the client was told.
Information: the restricted list is where MNPI (creditor groups, private deals, wall-crossings on block trades or new issues) is controlled; expert networks, data vendors with alternative data and the firm’s own private markets teams are the current MNPI risks; the FCA’s insider trading cases against managers are the reason for the wall.
Oversight of providers: the fund board approves and the adviser oversees the administrator, custodian, transfer agent, pricing vendors, sub-advisers and the distributor; SOC 1 reports, KPIs and due diligence are the evidence; the outsourcing of middle office to the custodian banks makes this oversight the control over most of the operations chain.
Inside the Firm›Settlement and Custody
Settlement, Custody and Asset Servicing
After the trade: confirmation matching with the broker, settlement instructions to the custodian, settlement at the depositories the custodian reaches, fails worked every morning, the daily reconciliation of positions and cash to the custodian and the administrator, corporate actions with elections and income, proxy voting and the lending interface. The custodian does the settlement and the servicing; the manager instructs, reconciles and decides.
Who uses what:confirmation CTM for securities, platforms and MT300 for FX, Markitwire and MarkitSERV for swaps, ClearPar for loans, email for the restinstructions MT541/543, MT304, pacs.009 through SWIFT or the custodian portal; ALERT for SSIsfails and reconciliation fail queue, reconciliation tool (SmartStream TLM, Duco), three-way IBOR / custodian / ABORasset servicing MT564/565/566 corporate actions, income and tax reclaims, proxy service (Broadridge, ISS), lending agent reports

The manager is never at the depository: everything it holds is a position at its custodian, and everything it does after the trade is an instruction to that custodian and a reconciliation against it. The fail queue, the breaks and the election deadlines are the daily work; the custodian’s cut-offs are the clock.
United Kingdom: the depositary holds the assets with strict liability under the fund rules, settling at CREST and the ICSDs and through its global network; the T+1 code’s allocation and confirmation deadlines apply, there are no cash penalties on fails (the exchanges’ and the CCPs’ buy-in rules discipline them), and settlement is T+2 until October 2027.
The custodian relationship: a global custodian (BNP Paribas Securities Services, State Street, JPMorgan, Northern Trust, Citi, HSBC) holds the funds’ assets through its own network of sub-custodians in each market, settles, services income and corporate actions, runs tax reclaims, lends securities, provides cash accounts and FX, and often the fund accounting and the middle office; the fund board or the client appoints it; the CASS rules (206(4)-2) requires qualified custodians for an adviser’s clients.
Cut-offs and messages: SWIFT MT (and ISO 20022 MX from 2025) carry instructions and statements; the custodian’s cut-off per market is hours before the depository’s; the same-day matching expectation under T+2 (matched under the T+1 code’s allocation and confirmation practices for CTM) moved the manager’s confirmation work into the evening; foreign markets add pre-matching, local holidays, FX funding and later cut-offs for Asia.
Fails: a fund’s purchase fails when the broker cannot deliver (short inventory, a fail upstream); a fund’s sale fails when the shares are on loan, pending a corporate action, or at a different custodian after a transition; the cost is the cash not received or the penalty (CSDR in Europe); fail rates are a KPI for the broker review and the custodian review.
Corporate actions are the most error-prone operations process: voluntary events with deadlines, entitlement calculations, tax, and data that differs between the custodian, the vendor and the administrator; the control is the corporate actions system with event tracking, a PM election workflow and the reconciliation of entitlements; a missed tender or a wrong election is an operational error the firm reimburses.
Inside the Firm›Collateral and Margin
Collateral and Margin Across Dealers, clearing brokers and Custodians
Every derivative, TBA and repo the funds hold produces a margin flow: variation margin calls under the CSAs with the dealers, cleared margin through the clearing brokers, initial margin under the UK EMIR margin rules to segregated accounts. The collateral team agrees the calls on Acadia and the clearing broker portals, the cash team funds them, the custodian moves the cash or the gilts, and the balances are reconciled daily. Risk watches the exposure and the liquidity the calls could demand.
Who uses what:agreements CSAs, clearing broker agreements, MSFTA, MRA, the UK EMIR margin rules custodial arrangements in the collateral system (OMS module, CloudMargin, the custodian’s service)calls Acadia MarginSphere for CSA VM and the UK EMIR margin rules IM, clearing broker portals for cleared margin, email for the rest; disputes under the CSAmovements pacs.009 cash, MT540-543 securities, triparty for IM; CHAPS, CREST, CREST through the custodianrisk and reporting risk engine for exposure and stress, portfolio reconciliation on Acadia, the UK UCITS reporting to the FCA and the COLL derivatives rules reporting, client reports

A fund with derivatives is a fund with daily collateral flows, and the flows need cash: the collateral team and the cash team are the same morning process. The dealers and the clearing brokers are on one side, the custodian on the other, and the manager agrees the numbers in between.
United Kingdom: the fund exchanges margin under the UK EMIR margin rules with its bank counterparties, posts initial and variation margin to its clearing broker for LCH and ICE Clear Europe, and holds its collateral at the depositary; the COLL collateral rules and UK SFTR’s reuse rules apply.
Margin regimes a fund can be in at once: bilateral VM under the CSA (daily, since 2017 for most funds), the UK EMIR margin rules IM for funds over GBP 8 billion AANA (two-way, segregated, SIMM), cleared margin through a clearing broker (IM and VM, LSOC segregation for swaps, 4d(a) for futures), TBA margin under the firm’s margin policy, repo haircuts and margin under the MRA, prime brokerage margin for hedge funds; each has its own calls, cut-offs and statements.
Operations: the collateral management function is often outsourced to the custodian (BNP Paribas Securities Services, State Street, JPMorgan offer it) or run on a vendor platform; the manager keeps the agreement data, the valuation, the dispute decisions and the funding; Acadia is the common rail for calls, IM calculation and portfolio reconciliation; the clearing brokers each have their own portal and file.
Liquidity: a margin call is a same-day cash need; the COLL derivatives rules program and the 22e-4 liquidity program both require the fund to hold enough liquid assets for stressed calls; the 2020 dash for cash and the 2022 UK LDI crisis were margin-call liquidity events; the cash team’s forecast carries the expected calls and a buffer.
Collateral the fund holds: a dealer’s VM posted to the fund is cash or gilts the fund holds (often at the custodian, sometimes rehypothecable under the CSA); cleared IM at the clearing broker is the fund’s asset at the clearing broker; the UK EMIR margin rules IM is segregated and cannot be reused by either side; the accounting shows collateral as assets and liabilities and the UK UCITS reporting to the FCA reports it.
Inside the Firm›Cash and Liquidity
Cash Management and Fund Liquidity
The cash team starts each day from the custodian’s balances and the forecast of settlements, income, margin, expenses and flows, tells the PMs what to invest or raise, sweeps the residual cash, arranges the FX for the flows, and funds the margin calls and the payments through the custodian’s cut-offs. Risk runs the liquidity program under the COLL liquidity rules and the redemption stress tests; the line of credit covers timing gaps.
Who uses what:forecast cash forecast from MT950, the IBOR and the OMS; transfer agent flowsinvesting sweeps into money funds, repo through the custodian, deposits under the cash policy; futures overlay by the PMflows FX desk or custodian standing instructions for currency; pacs.009 payments with dual approval; sweeps by MT502 or portalliquidity the liquidity buckets (Bloomberg LQA, MSCI, ICE), HLIM, stress tests, the UK UCITS reporting to the FCA and N-RN; lines of credit and interfund lending

A fund’s cash is at its custodian and its flows come from its investors: the cash team sits between the two and the PMs, and its day is a forecast, a set of actions before the cut-offs and a check that nothing went into overdraft. The liquidity program is the regulatory frame around the same question: can the fund pay its redemptions.
United Kingdom: the fund’s liquidity runs under the COLL liquidity rules and the FCA’s liquidity management guidance (swing pricing and dilution levies, deferred redemption, suspension), with the notice periods of the LTAF and the rules on funds investing in inherently illiquid assets after the 2019 property fund suspensions; the cash sits with the depositary within the deposit limits or in an MMF; liquidity stress testing is a standing requirement.
Cash on a fund: uninvested cash is a drag, an overdraft is a cost and a compliance exception, and a missed settlement is a fail; the cash policy sets the target, the sweep vehicles, the bank limits and the overdraft rules; most managers now run a central cash function with a forecast system (the OMS module, or a vendor) fed by the custodian and the transfer agent.
Flows: a mutual fund’s investors subscribe and redeem daily at the NAV through the transfer agent and the distributors’ platforms (omnibus accounts at the brokerages and the occupational pension recordkeepers), settling T+2; the estimates during the day and the finals after 16:00 are the biggest uncertainty in the forecast; ETFs replace this with creations and redemptions through APs; institutional accounts announce flows ahead.
the COLL liquidity rules (2018): the liquidity risk management program with a program administrator, classification of every holding into four buckets, a highly liquid investment minimum, the 15% limit on illiquid investments, redemption stress testing and board reporting; the UK UCITS reporting to the FCA reports the buckets monthly; the FCA’s liquidity management rules make swing pricing, gates and redemption fees available to every fund, with the fund rules review of 2024 and 2025 behind them.
Credit lines and interfund lending: a committed line with a bank group, drawn for redemption timing gaps, and an interfund lending program under an exemptive order where one fund lends cash to another; both are rare in use and reported to the board; a hedge fund’s liquidity management is its margin and financing with the prime brokers, its investors’ redemption terms (gates, notice periods) and its unencumbered cash.
Inside the Firm›Fund Accounting and NAV
Fund Accounting, the NAV and the Books of Record
The administrator keeps the accounting book of record from the manager’s trades and the custodian’s settlements, accrues income and expenses, prices the portfolio, strikes the NAV and prepares the financial statements; the manager’s fund finance team reviews the NAV before release, reconciles its own investment book of record to it every morning, handles NAV errors, distributions and tax, and oversees the administrator. Two books, one truth, reconciled daily.
Who uses what:books ABOR at the administrator (accounting system), IBOR at the manager (OMS or dedicated), custodian records; three-way reconciliationNAV pricing hierarchy, NAV pack and review, release to the transfer agent and the London Stock Exchange by 18:00 London time; NAV error policyclose month-end trial balance, ASC 946 financial statements, audit, N-CSR; distributions under Subchapter M, taxoversight performance reconciliation, regulatory data, administrator KPIs and SOC 1

Jump to12 steps, hover or click any of them
The NAV is the product a fund sells every day, and it is produced by a vendor from the manager’s data: the daily review, the reconciliation and the error policy are how the manager stays responsible for a number it does not compute. The IBOR exists so the PM sees today’s book, not yesterday’s accounting.
United Kingdom: the NAV is struck by the administrator (often the depositary’s group) under the COLL valuation rules with the ongoing charges figure disclosed in the KIID; the annual and half-yearly reports go to the FCA and the investors, with the authorised fund manager’s assessment of value; Edinburgh, Dublin and the Channel Islands host most of the administration.
IBOR and ABOR: the investment book of record is the manager’s real-time view (positions and cash including today’s trades and expected flows) for portfolio management and compliance; the accounting book of record is the administrator’s settled-and-accrued view for the NAV; most managers keep an IBOR in the OMS or a dedicated platform (Eagle, SimCorp) and reconcile it to the ABOR and the custodian daily; a shadow NAV computed by the manager is the stronger control.
NAV production: the administrator (the custodian bank’s fund services arm, or an independent such as SS&C or Citco for hedge funds) strikes the NAV under a service agreement with cut-offs, pricing sources and an error policy; the manager’s review before release is the control; NAV errors are measured against the industry’s materiality (half a cent per share or 50 basis points) and corrected by reprocessing and reimbursement; the fund board is told.
Accounting and tax: US funds report under ASC 946 (investment companies) with the schedule of investments, financial highlights and the expense ratio; a fund elects RIC status and must distribute substantially all income and gains, which the tax team computes from the books with the disposal and repurchase, straddle and PFIC adjustments; ETFs use in-kind redemptions to limit gains; hedge funds allocate P&L to partners by lot in the partnership accounting.
Oversight: the fund board approves the administrator and the custodian yearly on the adviser’s due diligence; the SOC 1 report, the KPIs and the service reviews are the evidence; under the FCA’s outsourcing proposals and the existing compliance rule, the adviser remains responsible for the outsourced function.
Inside the Firm›Performance and Client Reporting
Performance Measurement and Client Reporting
Performance is computed daily per account from the books, compared with the licensed benchmarks, attributed monthly, aggregated into GIPS composites, checked by compliance under the UK MiFID marketing rules, and delivered to clients, consultants, distributors and data vendors in reports, portals and files. Fee invoices run off the same values. Every published number has to reconcile to the NAV or the IBOR and to the client’s own custodian.

The investment result becomes a number through the performance system and a document through the reporting function; between the two sit the benchmark license, the GIPS composite and the compliance review. The client’s question is always the same (why this return) and the answer is the attribution.
United Kingdom: performance is presented under GIPS for institutional clients and in the KIID and the fund reports for retail; the platforms’ and the advisers’ ex post costs and charges reports under COBS carry the fund’s costs to end clients, and the sustainability labels under the SDR frame the marketing.
Performance standards: GIPS (the CFA Institute’s Global Investment Performance Standards) govern how a firm presents composite performance to prospects; the FCA Marketing Rule (2022) governs performance in advertising for US advisers (net and gross, standard periods, hypothetical performance conditions); fund performance in the prospectus follows Form N-1A’s rules; all three read from the same performance system.
Client reporting at scale: institutional clients receive tailored reports on a portal, consultants receive database feeds (eVestment, Mercer), fund investors receive factsheets, shareholder reports and the website; the reporting function is a production line (data, templates, approvals, delivery) on a monthly calendar, often on a vendor platform (Vermilion, Seismic, the performance system’s reporting module).
Fees: institutional fees are invoiced on the IMA’s schedule (tiers, most-favored-nation clauses, performance fees with hurdles and high-water marks, fulcrum fees for funds); fund fees accrue in the NAV; fee billing errors are a common FCA exam finding, so the invoice runs from the accounting values and compliance tests a sample.
Data vendors and ratings: Morningstar, Lipper and others compute fund ratings from the NAVs and the holdings the fund files and feeds; platform placement and flows follow the ratings; the fund’s data feeds (daily NAV, monthly holdings, the prospectus data) are a sales-critical operations output.
Inside the Firm›Risk Oversight
Risk Oversight, Derivatives and Liquidity Programs
Risk sets the limits, computes exposures and VaR overnight from the IBOR in the risk engine, reports exceptions to the PMs each morning, monitors counterparties, runs the COLL derivatives program and the liquidity stress tests, validates the models, keeps the error log, and reports to the risk committee, the fund board and the regulators. It is the second line: the PMs own the risk, risk measures and challenges it.

An asset manager’s risk function measures other people’s risk: the funds’ and the clients’. Its tools are models the firm configures rather than builds, its authority is the limit framework and the board, and its two named regulatory roles (derivatives, liquidity) are where the FCA made the function explicit.
United Kingdom: the risk management function under COLL and the UK AIFM rules: the global exposure (commitment or VaR), the counterparty limits, the liquidity stress tests, the leverage reporting under the Annex IV report; the LDI mandates hold the Bank of England’s resilience buffer since the 2022 gilt crisis; the sustainability risks under the SDR.
Risk at a manager versus a bank: no capital, no trading book of its own, no regulatory capital models; the risks are the clients’ (market, credit, liquidity) and the firm’s (operational, reputational, counterparty); the functions are investment risk (second line to the PMs), operational risk and compliance; the fund board and the regulators are the audience.
The two FCA programs: Rule the COLL derivatives rules (2022) requires a derivatives risk management program with a derivatives risk manager approved by the board, a VaR limit (relative 200% of a designated reference portfolio or absolute 20%), stress testing, backtesting and board reporting, for any fund using derivatives beyond the limited user threshold; the COLL liquidity rules (2018) requires the liquidity program with a program administrator, classifications, the HLIM and board reporting.
Counterparty risk for a fund: unsettled trades (DVP limits it to a day), OTC derivatives net of collateral, margin at the clearing broker and the prime broker (the 2008 and MF Global cases), cash at banks and money funds, securities lending collateral reinvestment; the limits, the collateral terms and the diversification of providers are the controls; a fund’s exposure to its own custodian is a separate item.
Operational risk: trade errors (wrong side, wrong size, wrong account) are the most frequent; the error policy decides who bears the loss (the adviser, usually) and the error log feeds the risk and control self-assessment, the board report and the FCA exam file; the FCA’s rules on cybersecurity and business continuity for advisers and funds add programs with their own reporting.
Inside the Firm›Regulatory Reporting
Regulatory Reporting, From the Fund Reports to the DTR 5 Notifications
An asset manager’s regulatory reporting is mostly about holdings and ownership rather than transactions: the UK UCITS and MMF reports to the FCA, the Annex IV reports for the AIFs, the ownership thresholds (the DTR 5 notifications, the net short position reports, the managers’ transactions under UK MAR and the foreign rules) monitored daily, the FCA’s trade repository disclosures, the fund census and the statistical reports to the central banks, and the UK EMIR and UK SFTR reports that fall on the fund rather than the dealer. Compliance owns the calendar, the data team builds the files from the books, and every figure must reconcile.
Who uses what:holdings the UK UCITS reporting to the FCA, the UK MMF rules reporting, the quarterly holdings disclosure (none in the UK) and the net short position reports under the UK short selling rules, built from the ABOR and the security master by the reporting hub (internal, administrator, Confluence, Donnelley)thresholds daily aggregation against 5% and 10% and foreign thresholds in the compliance engine (Fundapps or the OMS); DTR 5 notifications at 3%, the managers’ transactions rules of UK MAR filingsadviser and private funds the Annex IV report under UK AIFMD, the firm’s terms of business, the Annex IV report, the LEI (no large trader identification in the UK), LEIs, TIC formsfund filings the annual report, N-CSR, 24f-2, N-PX, 485 prospectus updates, XBRLtransactions trade repository (through the dealer), the UK SFTR report (through the agent), the APA and transaction reporting (through the brokers); EMIR delegated

The sell side reports what it traded; the buy side reports what it holds and who it holds it for. The hard part is aggregation: every threshold and most forms count positions across every fund, account and affiliate the adviser controls, which is a data problem before it is a legal one.
United Kingdom: the funds report to the FCA (the COLL reports, the Annex IV reports for the AIFs, the MMF reports), the derivatives to a trade repository under UK EMIR and the financing transactions under UK SFTR; the thresholds are the DTR 5 notifications at 3% and every 1% above and the net short position reports to the FCA (0.2% under the 2025 regime, with aggregated publication); no 13F, no Form PF, no N-PORT.
The main forms for a US manager, for comparison: the UK UCITS reporting to the FCA (fund holdings, monthly), the UK MMF rules reporting (money funds, monthly), the annual report (fund census, yearly), N-CSR (shareholder reports), N-PX (proxy votes), 24f-2 (shares sold), the quarterly holdings disclosure (none in the UK) and the net short position reports under the UK short selling rules (adviser’s long and short positions, quarterly), DTR 5 notifications at 3% (5% ownership), the managers’ transactions rules of UK MAR (10% insiders), the LEI (no large trader identification in the UK) (large traders), the Annex IV report under UK AIFMD (private funds), the firm’s terms of business (the adviser), the Annex IV report and CTA-PR (commodity pools), TIC forms (cross-border), and the FCA’s N-RN for liquidity and the COLL derivatives rules events.
Aggregation: the quarterly holdings disclosure (none in the UK), the thresholds and the Annex IV report under UK AIFMD aggregate across every fund and account the adviser has discretion over, and sometimes across affiliates (a bank-owned manager aggregates with the bank); the compliance engine and the data warehouse must hold every position, including derivatives and shares on loan, with consistent issuer mapping; the foreign threshold rules (dozens of countries) are the reason specialist vendors exist.
Transaction reporting: unlike a dealer, a fund rarely reports transactions itself; swaps are reported by the dealer (the fund reports only trades with another non-dealer, or in Europe under EMIR where both sides report unless delegated); the APA, the APA and transaction reporting are the broker’s; the UK SFTR report is the lending agent’s; the fund keeps the UTIs and reconciles the repositories’ data against its books where it can access them.
Direction of travel: more frequent and more public holdings data (the UK UCITS reporting to the FCA monthly public from 2025, the net short position reports under the UK short selling rules short positions, the Annex IV report under UK AIFMD event reporting), more detail on liquidity and derivatives, and the FCA’s use of structured data to compare advisers; the response is a reporting hub with lineage from the books rather than a spreadsheet per form.
