Financial Markets Atlas: Foreign Bank in the UK

Where a Client’s Business Books: the Branch, the Designated Firm and the EU Entity Next Door

One client, the London books: a FTSE 100 engineering group takes a sterling revolver, FSCS-covered operating accounts and an FX and rates hedging program from the London branch of the national bank, and a sterling bond underwriting from the UK securities firm, while its US subsidiaries bank in New York; the branch keeps the risk as the group’s hub, the Frankfurt entity next door faces the EU clients and hedges back in, the bank’s capital stands behind the branch and the firm’s own behind the firm, and the PRA and the FCA read the map on reliance and risk appetite.

• The PRA’s approach to international banks: branches are welcome for wholesale business when the PRA can rely on the home supervisor and the group’s resolution strategy, with limits on retail and SME deposits (above about GBP 100,000,000 of FSCS-covered transactional deposits or 5,000 such customers, the PRA expects a subsidiary); a branch’s senior managers are accountable under the SMCR; the PRA may require subsidiarization where a branch grows beyond its risk appetite.
• The PRA-designated investment firm: a UK investment firm the PRA designates for its size and systemic importance (the large dealers, most of them the UK arms of the US banks), supervised by the PRA under the UK CRR like a bank rather than by the FCA under the IFPR; the US groups’ London securities companies are designated firms, the group’s LCH members and gilt-edged market makers, and the largest balance sheets among the UK investment firms.
• London as the hub: the group’s EMEA treasury (Eurodollars and sterling raised in London, euros with the Frankfurt entity), the European hours of the bank’s global trading books, the LCH membership for the group’s cleared swaps, the coverage of the UK, Swiss, Middle Eastern and African clients, and the back office for the region; Brexit moved the EU clients and a share of the trading to Frankfurt, Paris and Dublin and left London the larger piece.
• The FSCS at a branch: a PRA-authorised branch of a non-UK bank is a member of the FSCS and its eligible deposits are covered to GBP 120,000 (since December 2025), a protection the FDIC does not give to the deposits of a US bank’s foreign branches; since 2013 the US banks make their London deposits dually payable (in London and in the US) so that they rank as deposits, not as general claims, under the US depositor preference in a receivership of the bank.

The Booking Model: a Booking Inside the Bank, a Contract Between the Firm and the US Dealer

A UK corporate’s sterling swap dealt and kept in the London branch’s own book, its dollar swap booked in the branch but managed in the bank’s global dollar book by an internal transfer, and its Treasuries bought through the UK securities firm from the US broker-dealer by a contract between two entities; the clearing, margin and reporting on both sides, the PRA’s and the OCC’s views of the booking arrangements, and the transfer pricing for two tax authorities.

• The US banks’ booking: the large US banks book most of their derivatives in the national bank (the FDIC-insured, OCC-chartered entity) and use its London branch as the booking location for European clients, with the securities business in the UK broker-dealer; the swap push-out rule of 2013 was narrowed in 2014, so the bank entity keeps the rates, FX and most credit derivatives, and the branch is where the bank faces Europe.
• Two rulebooks on one trade: the London branch is a UK counterparty under UK EMIR (reporting, risk mitigation, clearing where applicable) and the national bank is a CFTC-registered swap dealer worldwide (business conduct, reporting to a US swap data repository, the US clearing and margin rules); the CFTC’s cross-border rules and its comparability determination for the UK decide which substituted compliance applies, and the bank reports to both.
• The PRA’s booking expectations: the PRA expects a firm’s booking arrangements to be documented, understood by its board, with the risk management where the risk is booked, with the ability to assess and change the model, and with a senior manager accountable; the OCC’s view is the mirror: the branch’s trades are the bank’s, examined with the global business as one under the market risk rule and the Volcker rule.
• Transfer pricing of a branch: the authorized OECD approach attributes to the branch the profit a separate enterprise would earn from the functions it performs and the risks its people manage; HMRC taxes that profit (25% corporation tax and the 3% bank surcharge) and the IRS taxes the bank’s worldwide income with a credit for the UK tax; the global book’s profit is split by the desks’ contributions, documented in the group’s transfer pricing study.

The London Hours: the Global Dollar Book Through the Branch, the Sterling Book at Home

The bank’s global dollar rates book passed from Hong Kong to London to New York and back inside one legal entity; the sterling and gilt books that live in London only and the euro books shared with Frankfurt by contract; the settlement and margin in the European hours through the Bank of England, LCH and the head office’s dollar access; one risk system with limits by desk and by entity; the P&L closed by region for three regulators and two tax authorities.

• The dollar day: the dollar rates market trades around the clock with the London morning (08:00 to 12:00 London, before New York opens) as the busiest hours outside the US; a US bank’s London branch runs the global book in those hours and hands it to New York at midday ET; the sterling market has no such relay, so the sterling book opens and closes in London.
• One legal entity, three desks: the Hong Kong branch, the London branch and the New York head office are the same national bank, so the book moves by handover and internal transfer, with the positions in one trade capture system and one risk system; the Frankfurt entity and the UK securities firm are separate companies, so their positions move by contracts with the bank.
• The entity views: the PRA reads the London branch’s risk, limits and booking model (its share of the global book and the sterling book entire) and the UK firm’s own books; the OCC and the Fed read the bank’s and the group’s whole under the market risk rule and the Volcker rule, with the London hours inside; the regulators compare notes in the supervisory college the Fed chairs.
• Three closes: London closes the branch’s ledger for the UK (corporation tax and the bank surcharge on the attributed profit, the Branch Return, the FCA), New York closes the bank’s and the group’s (the call report, the FR Y-9C), and the global book’s P&L is split by desk for the transfer pricing; the branch’s accounts are in US GAAP inside the bank’s and restated for HMRC.

The London Dollar Book: Eurodollars, the Head Office Account and One Bank’s Dollars

Where a US bank’s London dollars come from and go: Eurodollar deposits and London CDs from central banks, corporates and money funds (uninsured, dually payable, outside Regulation D, inside the bank’s LCR), lent to the head office through the head office account or to the European dollar clients at the group’s funds transfer price; the group treasury’s dollar plan, the European dollar session and the handoff to New York; the Fed’s and the OCC’s view of one bank’s dollars and the PRA’s view of a branch that depends on its head office.

• Eurodollars: dollar deposits booked outside the US, a market the US banks’ London branches built in the 1960s when Regulation Q capped deposit rates at home and Regulation D required reserves on domestic deposits but not on foreign branch deposits; the caps are gone and the reserve requirement is zero since March 2020, but the market stays in London, where the depositors are and the hours join Asia and the US; a US bank’s Eurodollar deposits are its own liabilities, uninsured by the FDIC.
• Dually payable deposits: the US depositor preference statute of 1993 ranks deposits ahead of general creditors in a receivership of the bank but only deposits payable in the US; after the 2008 crisis the PRA asked the US banks to put their London depositors on the same footing as the US ones, and the FDIC’s 2013 rule confirmed that deposits payable both at a foreign branch and in the US count as deposits; the US banks’ London branches made their deposits dually payable, and the FSCS covers the eligible ones to GBP 120,000.
• The head office account: the positions between a branch and its head office are internal to one legal entity, so London’s lending to New York is a book entry, not an intragroup loan; it is nevertheless priced (at the group’s funds transfer price), reported (on the FFIEC 030 and the branch’s balance sheet) and watched by the PRA as the branch’s reliance on the group; a Japanese bank’s New York branch has the same account the other way round, borrowing dollars from a yen head office.
• The US liquidity rules: the LCR and NSFR apply to the bank consolidated (foreign branches included) and to the holding company; the Fed’s Regulation YY requires internal liquidity stress tests and a 30-day buffer at the holding company and the bank; the FR 2052a reports the liquidity position daily by legal entity and currency, so the Fed sees the London book every day; the PRA relies on that regime for the branch and reads the branch’s own data beside it.

Sterling Funding: CDs, Wholesale Deposits, the FX Swap From Dollars and the FSCS

How a US bank funds its sterling book: wholesale deposits, CDs and the money funds (FSCS-covered where eligible, dually payable, uninsured by the FDIC), dollars swapped into sterling at a basis that works in the dollar lender’s favor, sterling loans at the funds transfer price, the swap and the ladder rolled, the sterling book inside the bank’s currency stress and the FR 2052a, the PRA’s reading of the branch’s sterling data with the FSCS behind the deposits, and the reserves account and the Bank of England’s facilities as the one direct central bank backstop the branch has.

• The GBP/USD basis: the cross-currency basis on sterling is small and usually in the dollar lender’s favor (a few basis points below SONIA for the sterling borrower who brings dollars), because the market’s structural demand is for dollars, not sterling; a US bank swapping dollars into sterling earns the basis the Japanese bank pays on the other side of the same market, which is one reason the US banks fund sterling books cheaply.
• The FSCS at a branch: the eligible deposits (individuals, companies of any size, charities, but not banks, money funds or large public bodies) are covered to GBP 120,000 per depositor since December 2025 (GBP 85,000 before), the branch pays the deposit levy on the covered amount, and keeps the single customer view file the FSCS would pay from in seven days; the PRA’s branch policy expects the covered transactional deposits to stay small at a branch.
• Sterling in the US rules: the US LCR has no currency-level requirement, but the Fed’s Regulation YY internal liquidity stress tests must cover the material currencies, the FR 2052a reports the position by currency, and the OCC’s examiners read the sterling mismatch of the London branch; the PRA’s whole-firm reliance rests on that regime, with the branch’s own data and a sterling buffer by the group’s policy beside it.
• The Bank of England for a branch: a PRA-authorised branch of a non-UK bank can be an SMF participant with a reserves account and access to the Bank’s sterling facilities against pre-positioned collateral (and to the dollar repo on the Fed swap line, which a US bank does not need); the Fed’s discount window is open to the national bank at home, not to the London branch, so the branch’s dollar backstop runs through New York.

The Sterling Monetary Framework: the Reserves Account, the STR, the DWF and the Fed Behind

A US bank’s London branch as an SMF participant: the reserves account at Bank Rate with the floor system, the weekly short-term repo and the monthly ILTR as quantitative tightening drains reserves, the Discount Window Facility and the CTRF for a stress with the collateral pre-positioned and tested, the dollar backstop that runs through New York to the Fed’s discount window and standing repo facility, the payment day on the account with CHAPS, CREST and LCH, the Bank’s three roles beside the PRA and the FCA, and the small cost of sterling liquidity in the FTP.

• The Sterling Monetary Framework: the Bank of England remunerates all reserves at Bank Rate (the floor system), has no reserve requirement, lends reserves at the weekly short-term repo (seven days, Bank Rate, unlimited against level A collateral) and the monthly indexed long-term repo (six months, against levels A to C at auction spreads), and runs the Discount Window Facility (bilateral, 30 days, against the wide collateral set) and the Contingent Term Repo Facility (activated in a stress); the UK branches of non-UK banks are eligible as SMF participants.
• From quantitative easing to the STR: the Bank’s gilt purchases left the banks with abundant reserves; as the purchases unwind (quantitative tightening, with gilt sales and maturities), the Bank supplies the reserves the system needs through the STR and the ILTR, so that the facilities become the ordinary source of reserves rather than a stigma; the PRA expects every firm, branches included, to have tested the DWF.
• The Fed’s facilities: primary credit at the discount window (against pledged collateral, to the bank at home) and the standing repo facility (overnight repo against Treasuries and agencies at the top of the target range, for the primary dealers and the eligible banks) are the national bank’s dollar backstops; a foreign branch of a US bank borrows from its head office, not from the Fed; the Bank of England’s dollar repo operations on the Fed swap line exist for the UK banks and the other foreign banks.
• Three roles: the Bank of England sets monetary policy and runs the framework, supervises the banks and branches through the PRA (a part of the Bank since 2013) and the FMIs directly, and resolves failing firms; the FCA is a separate conduct regulator; a US bank’s branch meets the Bank as a lender, a supervisor, an overseer of LCH and CHAPS, and a resolution authority, and meets the Fed and the OCC at home in the same roles.

Sterling Payments for the Group: CHAPS, the Schemes, the Nostros and the Dollars Going Home

The London branch as the sterling clearer of a US bank: instructions from the head office (an internal account), the Frankfurt entity, the Asian branches and the correspondents, validated, screened against the UK, US and EU lists and routed to CHAPS, Faster Payments or Bacs, settled on the reserves account with the Bank of England’s intraday liquidity, reported back on MT950 and camt.053; the dollars going home by book entry through the head office’s own Fedwire and CHIPS access; AML and sanctions under two regimes; the group’s view on the FFIEC 030 and the OCC’s examination.

• CHAPS: the Bank of England’s RTGS system for sterling, open 06:00 to 18:00 with direct participants (the banks, the large foreign branches, some non-banks) settling across their reserves accounts; the throughput rules keep the participants paying through the day; the Bank operates and oversees it since 2017, and a branch’s CHAPS access is an important business service under the operational resilience rules.
• Two sanctions regimes on one branch: the branch applies the UK regime (OFSI, the Sanctions and Anti-Money Laundering Act) as a UK business and the US regime (OFAC) as part of a US bank, since a US person’s foreign branch is bound by the US sanctions wherever it operates; the two lists are not identical, and the Frankfurt flows carry the EU list too; the screening is one system with three lists and the reporting goes to three authorities.
• A US bank is its own dollar correspondent: the national bank in New York is a Fedwire participant and a CHIPS member, so its London branch’s dollars move by internal instruction and book entry and then through the US systems; a foreign bank’s London branch clears dollars through a US correspondent or its own New York branch; the mirror case is the Japanese bank’s New York branch clearing dollars for Tokyo on this page’s US version.
• The FFIEC 030: the Foreign Branch Report of Condition filed by the US banks for each foreign branch (annually, quarterly for the significant branches) with the balance sheet, the nostro and vostro balances and the memoranda; the branch is consolidated in the bank’s call report and the holding company’s FR Y-9C; the OCC examines the branch’s operations as the bank’s, with its examiners in London for the largest banks.

Intraday Liquidity: the Reserves Account, the Bank’s Free Intraday Credit and the Fed Behind the Dollars

The sterling day of a US bank’s London branch: the opening position and the collateral pre-positioned, the Bank of England’s free intraday liquidity drawn at 06:00 against the pool and repaid as the inflows settle, the queue by priority and the CHAPS liquidity saving mechanism within the throughput rules, the dollar intraday run by the head office at the Fed under the daylight overdraft rules, the afternoon inflows, CLS and the squaring at 18:00 at Bank Rate, the Basel intraday metrics for the PRA and the bank’s intraday across currencies for the Fed and the OCC.

• The Bank of England’s intraday liquidity: the CHAPS participants receive intraday liquidity free of charge against the collateral they pre-position with the Bank (an intraday repo, reversed by the end of the day), with no cap other than the collateral; the Fed charges for daylight overdrafts above the collateralized capacity under its payment system risk policy, so the sterling intraday is cheaper than the dollar one for a US bank.
• The CHAPS liquidity saving mechanism: the participants can submit payments to be settled in matching cycles that offset their outflows against the other participants’ inflows, reducing the liquidity each needs; the time-critical payments settle immediately; the throughput rules (50% of the day’s value by noon, 75% by 14:30) prevent the participants from hoarding liquidity and paying late.
• The Basel intraday monitoring tools (2013): the daily maximum intraday liquidity usage, the available intraday liquidity at the start of the day, the total payments sent and received, the time-specific obligations, the value of payments made on behalf of correspondents, and the stressed scenarios; the PRA collects them for the UK firms and the branches it asks, the Fed requires the intraday in the Regulation YY stress tests.
• The floor system and the close: with all reserves remunerated at Bank Rate, a surplus on the reserves account costs nothing against the market, so the branch does not need an overnight deposit facility or a precise squaring; the dollar side at the Fed is the same since interest on reserve balances, and the group’s treasury runs both accounts to a target rather than to zero.

Syndicated Loan Participation Under LMA Documentation, Booked in the Branch of a US Bank

A US bank’s London branch takes GBP 100,000,000 of a FTSE 100 group’s GBP 1,500,000,000 LMA revolver under English law: the invitation as a relationship lender on both sides of the Atlantic, the credit approval under a global line that counts the sterling and the dollar facilities together, the LMA agreement with the US lender’s OFAC and FCPA clauses, the draws funded by CHAPS at the sterling FTP, the life of the loan through the agent and ClearPar, the OCC’s examination with the SNC rating of the US twin, and the PRA’s reading on reliance.

• LMA and LSTA: the London market lends on the Loan Market Association’s forms under English law (the agent, the pro rata sharing, the majority lender votes, the transfer certificates), the New York market on the LSTA’s forms under New York law (assignments, the more borrower-friendly amendment thresholds, the different trading conventions); a US bank lends on both forms through its two branches, and its global credit line counts both.
• The US lender’s clauses: the US banks bring into the LMA market the representations and covenants they need as US persons, the OFAC sanctions clauses (no use of proceeds in sanctioned business, no sanctioned persons among the borrower’s group) and the anti-corruption clauses under the Foreign Corrupt Practices Act; the LMA forms accommodate them as lender-specific provisions, and the UK banks have their own under the UK regime.
• The Shared National Credit program: the Fed, the OCC and the FDIC review the syndicated credits above USD 100,000,000 shared by three or more supervised institutions and agented by a US bank, with one rating for all the lenders; a sterling LMA facility agented by a UK bank is not in the program, but the US bank’s branch carries the OCC’s own rating on it and the SNC rating of the borrower’s US facility beside it.
• A branch has no UK capital on its loans: the risk weight is the US one in the national bank’s ratios, the stress loss is CCAR’s, and the large exposure limit is the OCC’s single-borrower lending limit (15% of the bank’s capital) applied to the whole bank; the PRA reads the branch’s book in the Branch Return and its concentration in its risk appetite for the branch, with no UK ratio to apply to a branch.

Project Finance: an Offshore Wind Farm Under a Contract for Difference, Financed From London

A US bank as lender and hedge bank to a 1 GW UK offshore wind farm under a CfD: the mandate and the global project finance group, the structuring and the New York credit approval, the lender club with the European ECAs and the National Wealth Fund, financial close under English law with the security and the CfD direct agreement, the drawdowns over construction by CHAPS at the sterling FTP, the operations with the CfD, the waterfall and the hedges under UK EMIR and the CFTC, the OCC’s view of project finance in the bank’s book and the PRA’s reading of the branch’s exposures and climate risk.

• Contracts for difference: the UK’s support scheme for low-carbon generation since 2014; the generator receives from (or pays to) the Low Carbon Contracts Company the difference between a strike price set in the allocation round auctions and the market reference price for 15 years, which gives the lenders a fixed revenue to size the debt on; the allocation rounds set the pipeline the banks lend into.
• The US banks in European project finance: the large US banks lend to the European renewables and infrastructure projects from their London branches with global project finance groups split between New York, London and Asia, bring the US rules with them (the OCC’s guidance, the US risk weights, the CCAR losses, the FCPA and OFAC clauses) and count the deals in their sustainable finance commitments.
• The ECAs and the National Wealth Fund: the export credit agencies of the turbine and cable makers cover the tranches that finance their exports (EKF for Denmark, Euler Hermes for Germany, Atradius for the Netherlands) and the National Wealth Fund (the renamed UK Infrastructure Bank) co-lends on commercial terms to crowd in the banks; the covered tranche carries the ECA’s sovereign risk weight in the US and UK rules alike.
• Climate risk at the PRA: the supervisory statement of 2019 expects the firms, branches included, to manage the financial risks from climate change through their governance, risk management, scenario analysis and disclosure; the PRA reads the branch’s project book and its transition plans in that light and relies on the OCC for the credit quality, while the OCC’s own climate principles for the large banks apply to the bank as a whole.

Trade Finance: a Letter of Credit That Travels Inside One Bank

A letter of credit issued by a US bank’s London branch for a UK importer buying from a US exporter that banks with the same bank: the application against the trade line, the MT700 to the head office that advises and confirms as the same legal entity, the documents examined and paid in the US under UCP 600, the reimbursement by book entry on the head office account, the retailer’s payment with the FX, the screening against three sanctions lists and the UK trade controls, and the contingent in the bank’s books and the leverage ratio.

• UCP 600: the ICC’s Uniform Customs and Practice for Documentary Credits (2007), the rules every letter of credit incorporates; the banks deal in documents, not goods, the issuing bank’s undertaking is independent of the sale contract, and the documents must comply on their face; the examination within five banking days, the discrepancies and the waivers are the trade in practice.
• Advising and confirming inside one bank: a US bank’s foreign branch and its head office are one legal entity, so a credit issued in London and confirmed in New York carries one bank’s undertaking; the exporter gains the convenience of its own bank and the place of payment, not a second credit; in a foreign bank’s network the issuing branch and the confirming branch are often the same entity too, and the confirmation adds the confirming country’s payment undertaking.
• Trade sanctions on a US bank’s branch: the branch applies the UK regime as a UK business and the US regime as part of a US person, screens the parties, the goods (the dual-use and military lists), the vessels and the ports, and files with OFSI and OFAC; the trade-based money laundering guidance (the Wolfsberg principles, the FATF typologies) is the same on both sides.
• The contingent in the capital rules: a trade-related contingent (a documentary credit collateralized by the underlying shipment) carries a 20% credit conversion factor in the US and the UK rules alike, and the leverage ratio counts it at the same factor; the branch has no UK capital, so the US rules apply through the bank’s ratios and the PRA reads the contingents in the Branch Return.

The US Multinationals’ European Treasury Centers: Cash Management, Pooling and FX From London

A US technology group’s EMEA treasury in London served by its US bank: the mandate for one bank at home and abroad, the account opening and the KYC across the group, the payments and collections in sterling through the branch, euros through the Frankfurt entity and dollars through the head office, the sweeping, pooling and the in-house bank, the FX and the intercompany flows under UK EMIR and the CFTC, the parent’s view on one portal with the repatriation by book entry, the FSCS and the two conduct regimes on the branch’s deposits, and the bank’s view of global cash management as one business.

• Treasury centers: the US multinationals run their European cash from a treasury center (London, Dublin, Amsterdam or Switzerland) that pools the subsidiaries’ cash, lends to them as an in-house bank, hedges the group’s FX and manages the intercompany flows; the US banks’ global cash management (one portal, one API, the same bank in every country) is their proposition against the European banks’ local networks.
• Brexit and the euro accounts: a UK branch lost its passport to offer SEPA payment services across the EU, so the US banks moved the euro accounts of their European clients to their EU entities (Frankfurt, Dublin, Paris) and kept the sterling and the multicurrency accounts in London; the client sees the two entities on one portal, and the group’s KYC is run once with the local additions.
• Pooling: physical pooling sweeps the balances to a header account under intercompany loans (the simplest in the UK), notional pooling offsets the balances without moving them (allowed in the UK and some EU countries, restricted in others, and expensive for the bank under the leverage ratio since the gross balances count); the US bank offers both and the group’s tax advisers choose by country.
• The deposits at the branch: a corporate’s sterling deposits at a US bank’s London branch are the national bank’s, dually payable (so they rank as deposits in a US receivership), covered by the FSCS to GBP 120,000 per eligible company (companies are eligible since 2015, whatever their size), and counted as operational deposits in the bank’s US LCR at a 25% run-off; the corporate relies on the bank’s credit for the rest, so it banks with a G-SIB.

The Gilt Market: the DMO’s Auctions, the GEMMs, CREST and LCH RepoClear From a US Bank’s UK Firm

The UK securities firm as a gilt-edged market maker: the DMO’s bid-price auction at 10:00 with the GEMM’s obligations, the client orders and the pre-auction market, the allotment and the results, settlement in CREST on T+1 with the repo at LCH RepoClear, market making to the LDI funds and the pension funds with the 2022 lesson, the Bank of England’s gilt sales under quantitative tightening as the second seller, UK MiFIR and the PRA’s view of the firm’s own capital, and the group’s view of a sterling desk in a global rates business.

• The GEMMs: the Debt Management Office’s gilt-edged market makers (about seventeen firms, the UK arms of the US, European and Japanese banks among them) have the obligation to bid at the auctions, make markets to the investors and report turnover, and the privileges of the auction access, the DMO’s syndications and the switch auctions; the DMO ranks them quarterly and the syndication roles follow.
• Bid-price auctions: the DMO sells the conventional gilts by competitive bids at the prices each bidder names, each successful bidder paying its own price (a multiple-price auction), where the US Treasury sells at the single clearing yield (uniform price); the index-linked gilts are sold by uniform price; the DMO publishes the average price, the tail and the cover within minutes.
• The LDI lesson: in September 2022 the leveraged liability-driven investment funds of the UK pension schemes faced collateral calls as gilt yields rose, sold gilts into a falling market and forced the Bank of England into a temporary purchase program; the GEMMs’ market making and their repo lines to the LDI funds are watched by the Bank and the PRA since, and the funds hold larger buffers.
• The Volcker rule abroad: the proprietary trading ban of the Volcker rule exempts the obligations of a foreign sovereign traded by a foreign entity of a US bank (the UK firm’s gilt market making is in any case market making, a permitted activity); the UK firm is outside the SEC’s broker-dealer rules and inside the Fed’s consolidated supervision of the holding company, and the PRA supervises it as a UK firm under the UK CRR.

LCH SwapClear: the UK Firm as the Group’s Clearing Member for the EMEA Clients, CME on the Other Side

The UK securities firm’s clearing business at LCH SwapClear: the memberships (the firm for the EMEA clients, the national bank for its house book, the US broker-dealer at CME), a Dutch pension fund’s swap given up for clearing, the registration, the novation and the margin in segregated accounts, the CME-LCH basis and the choice of CCP, the daily cycle of variation margin, compression and the default fund, the client reports and the porting arrangements, the Bank of England, the PRA and the CFTC on the clearing, and the group’s view of client clearing as one global business.

• LCH SwapClear: the London clearing house’s interest rate swap service clears most of the world’s cleared swaps in the major currencies; its members are the dealers (the UK firms and the national banks of the US groups among them), its clients clear through them under the client clearing rules of UK EMIR, EU EMIR and the CFTC; the Bank of England supervises it as a UK CCP, ESMA recognizes it for the EU clients under a time-limited equivalence, the CFTC as a derivatives clearing organization.
• The CME-LCH basis: the same swap clears at either CCP, and the prices differ by a few basis points because the margin models, the funding of the margin and the balance of the client flows differ (the US asset managers’ receiving at CME, the European funds’ at LCH); the dealers trade the basis and route the clients to the cheaper CCP where the rules allow; it is one of the places where the group’s two memberships earn.
• Client clearing: the clearing member guarantees its clients’ performance to the CCP, calls them for margin with its own add-ons, segregates their collateral (omnibus or individually segregated accounts under UK EMIR, the legally segregated operationally commingled model under the CFTC), keeps the porting arrangements for its own default and carries the leverage ratio exposure of the guarantee (reduced by the client margin offset the US and UK rules allow since 2020 and 2021).
• The US clearing member abroad: a UK firm clearing for US clients registers with the CFTC as a futures commission merchant or relies on the CFTC’s exemption for foreign clearing members clearing for US customers through a US FCM; the UK firm clears the EMEA clients and leaves the US clients to the US broker-dealer, which is an FCM and a CME and LCH member of its own; the Fed sees the group’s clearing in the holding company’s capital and the resolution plan.

Prime Brokerage to a London Hedge Fund: Margin Lending, Stock Loan and CASS From a US Bank’s UK Firm

The UK securities firm as prime broker to a London equity long-short fund: the prime brokerage agreement with the margin terms and the contractual rehypothecation, the onboarding with the CASS classification and the credit limits, the longs financed, the shorts borrowed and the US exposure taken synthetically, the stock loan and the financing of the book, the daily margin call and the portfolio report with the Archegos lesson, the settlement and custody across CREST, DTC and Euroclear, CASS, SFTR, the short selling rules and the PRA’s capital, and the group’s prime brokerage across the UK firm and the US broker-dealer.

• Prime brokerage: the bundle a hedge fund buys from a dealer, the custody of its assets, the financing of its longs on margin, the borrowing of its shorts, the synthetic exposure through swaps, the reporting and the introductions; the London prime brokers are the UK firms of the US banks and a few European ones, since the business needs a dealer’s balance sheet and a global stock loan desk.
• CASS and rehypothecation: the FCA’s client assets rules (CASS 6 for custody assets, CASS 7 for client money) require segregation and reconciliation and a monthly CMAR report to the FCA, unless the client transfers title to the assets as collateral; a UK prime broker’s right to rehypothecate the fund’s assets is contractual and usually capped at 140% of the fund’s indebtedness by analogy with the US rule, where Rule 15c3-3 caps it in law; the Lehman London estate of 2008 showed what the difference means.
• Archegos: the family office that defaulted in March 2021 on total return swaps with six prime brokers, each of which saw only its own slice of a concentrated book and lost together more than USD 10,000,000,000; the PRA’s and the Fed’s reviews since ask the prime brokers for the fund’s whole leverage, stress-based margin with concentration add-ons, and a counterparty risk function that can say no.
• Two entities, two rulebooks: a US bank’s UK firm prime-brokes under the FCA’s CASS and the PRA’s capital rules, its US broker-dealer under the SEC’s Regulation T margin, Rule 15c3-3 customer protection and FINRA; the funds choose the entity by their own rules (a US fund under ERISA or the Investment Company Act in the US entity, a Cayman fund managed from London in the UK firm), and the group runs one risk view across them.

US Securities for UK Investors: the UK Firm, the US Broker-Dealer and the Overseas Persons Exclusion

A UK insurer’s US Treasuries and US equities bought through the UK securities firm and executed by the US broker-dealer: the order under the UK conduct rules, the execution in New York as a contract between two entities, the clearing and settlement at FICC and DTC on T+1 with the Treasury clearing mandate, the insurer’s settlement, custody and dollars, the coupons, dividends and the withholding tax under the treaty, UK MiFIR and the overseas persons exclusion on the UK side, and the SEC, FINRA and the Fed on the US side.

• The overseas persons exclusion: under the UK’s Regulated Activities Order a non-UK firm may deal with or for UK persons without UK authorization if it does so from outside the UK with or through a UK-authorised firm, or with UK clients it has not solicited (the legitimate approach test); the US broker-dealer uses it for its dealings with the UK firm and its unsolicited institutional business; the FCA’s review of the overseas regime since Brexit has kept it with conditions.
• Rule 15a-6: the SEC’s exemption lets a foreign broker-dealer deal with US institutional investors through a registered US broker-dealer that chaperones the trades and keeps the records, so the UK firm sells gilts to US investors through the US broker-dealer without SEC registration; the two rules are the mirror of each other and the two dealers of one group use both.
• US settlement: US equities settle on T+1 since May 2024 (NSCC and DTC), Treasuries on T+1 at FICC and Fedwire Securities, with the SEC’s Treasury clearing mandate bringing the cash trades into FICC by the end of 2026 and the repo by mid-2027; the UK equities move to T+1 in October 2027 with the EU; a UK firm trading US securities lives on T+1 before its home market does.
• Withholding: Treasury interest paid to a foreign holder is exempt from US withholding under the portfolio interest exemption, US dividends are withheld at 30% reduced to 15% (or 5% for a corporate shareholder above 10%) under the UK-US treaty on the holder’s W-8BEN-E through the custody chain; the qualified intermediary rules put the paperwork on the custodians and the firm.

The Branch Under the PRA’s Approach: No Capital, Reliance on the Fed and the OCC, the Branch Policy

How the PRA supervises a US bank’s branch without capital: the bank’s US Basel III and CCAR in New York stand behind it, the branch policy keeps it wholesale with limited retail, the FSCS covers the deposits the FDIC does not, the PRA relies on the Fed and the OCC under an equivalence assessment refreshed through the college, the branch reports its own Branch Return and liquidity data beside the FFIEC 030 at home, its senior managers answer under the SMCR, and a weakening bank brings reduced reliance, restrictions and in the end subsidiarization.

• The PRA’s approach to international banks (the supervisory statement of 2021): the PRA decides between branch and subsidiary on the home regime’s equivalence, the resolution strategy, the information it can get and the branch’s business (wholesale, with limited retail and SME deposits); it supervises a branch on reliance with its own risk appetite, and it can require a subsidiary; the FCA supervises the branch’s conduct under its own approach to international firms.
• No pledge, no endowment capital: unlike New York for a foreign bank’s branch and the EU under CRD VI, the UK asks a branch for no assets held locally and no capital equivalent; its protections are the FSCS for the depositors, the branch policy for the size of the retail book, the reliance on the home regime for the solvency and the resolution recognition for the end game; a UK liquidity requirement can be imposed where the reliance does not hold.
• The SMCR for a branch: the senior managers regime applies to the UK branches of overseas banks with a reduced set of functions (the head of overseas branch, SMF19, as the senior manager responsible for the branch, with the finance, risk, compliance and money laundering functions where they apply), the certification regime for the material risk takers and the conduct rules for everyone; the statements of responsibilities and the duty of responsibility make the accountability personal.
• Compared with the US page: a foreign bank’s New York branch pledges assets and is examined on its own ROCA rating with the IHC beside it; a foreign bank’s EU branch holds endowment capital and local liquidity under CRD VI with the subsidiary beside it; the US bank’s London branch holds nothing locally, insures its deposits, answers through named managers and is supervised on reliance, with the designated firm beside it; three hosts, three answers to the same question.

The PRA-Designated Investment Firm: UK CRR Capital, Pillar 2 and Internal MREL

The UK securities firm as the entity where the UK holds the group’s capital: UK CRR capital with the buffers and the PRA’s Pillar 2A and buffer, paid in by the holding company and counted twice, internal MREL to the group the Bank of England can write down, the ICAAP and the firm’s own stress tests inside the group’s CCAR, a board and a risk function of its own under the SMCR, the large exposure and CCP capital rules, the operational resilience rules on the clearing, the prime brokerage and the market making, and the reporting of a UK bank.

• PRA designation: the PRA designates the UK investment firms whose size and activities make them systemic (the large dealers, most of them the UK arms of the US banks) and supervises them under the UK CRR like banks, with the FCA for conduct; the other investment firms are supervised by the FCA under the IFPR with the K-factors; a designated firm has a reserves account at the Bank of England and may be an SMF participant and an LCH member.
• Pillar 2 in the UK: the PRA sets a firm-specific Pillar 2A requirement for the risks not captured by Pillar 1 (credit concentration, interest rate risk in the banking book, operational risk, pension risk) and a PRA buffer from the stress test results and the firm’s governance, in its periodic review of the ICAAP; the countercyclical buffer is set by the Financial Policy Committee; the UK’s implementation of the final Basel III rules runs from 2027, the US endgame on its own timetable.
• Internal MREL for a UK subsidiary of a foreign G-SIB: the Bank of England sets internal MREL for the material UK subsidiaries of overseas groups at 75% to 90% of what an external requirement would be, met with capital and eligible liabilities issued to the group with a contractual trigger the Bank can pull; the design supports the holding company’s single point of entry under Title II, with the Bank’s own resolution of the UK entity as the fallback.
• Operational resilience: the PRA’s and FCA’s rules (2021, with the impact tolerances to be met by March 2025) require a firm to identify its important business services, set the maximum tolerable disruption for each, map the people, processes, technology and third parties behind them and test the tolerances; for a US bank’s designated firm the clearing membership, the prime brokerage and the market making are the services, and the group’s US technology centers and the cloud providers are the third parties.

Liquidity: Whole-Firm Reliance for the Branch Under the US Rules, the UK LCR for the Firm, the Bank’s Facilities

The liquidity rules on a US bank’s UK operations: the branch supervised on whole-firm reliance with a buffer of reserves and gilts by the group’s policy and the PRA’s expectations, the designated firm on its own UK LCR and NSFR with the PRA110 report, the stress tests of both inside the group’s Regulation YY stress for the Fed, the US LCR, the resolution liquidity rules and the FR 2052a at home, the PRA110 and the Branch Return as the UK reporting, the contingency funding plan with the Bank of England’s facilities pre-positioned and the Fed’s behind the bank, and the transfer pricing that passes the cost of the buffers to the businesses.

• The PRA’s liquidity approach to branches: the PRA does not apply the UK LCR and NSFR to the branches of non-UK banks; it relies on the home supervisor’s regime for the whole firm where it judges it adequate (the whole-firm approach), collects the branch’s own data and stress tests, and may impose a UK-specific requirement (liquid assets held in the UK) where the reliance does not hold or the branch’s business warrants it; the Bank of England’s facilities are open to the branch as an SMF participant.
• The designated firm’s liquidity: the UK LCR and NSFR as onshored and amended by the PRA (the UK’s definitions of high-quality liquid assets, the outflow rates, the treatment of the margin and the client clearing), the PRA110 liquidity report (the maturity ladder and the metrics, monthly, more often in a stress), the ILAAP and the PRA’s liquidity supervisory review; the firm holds its own buffer and cannot count the group’s.
• The home rules: the US LCR and NSFR apply to the bank consolidated (the foreign branches inside) and to the holding company; the Fed’s Regulation YY requires internal liquidity stress tests by entity and currency and a 30-day buffer; the resolution liquidity rules (RLAP for the adequacy, RLEN for the execution need) in the 165(d) plan tell the group how much liquidity each material entity must have and where; the FR 2052a reports it all daily; the PRA relies on this regime and reads the branch’s data beside it.
• The cost: liquid assets held against stressed outflows earn less than the loans they replace, and the funds transfer pricing allocates the cost to the businesses whose liabilities need them; the branch’s sterling premium is small because reserves earn Bank Rate and the Bank of England’s facilities stand behind the branch directly; the London dollar book carries the group’s dollar liquidity premium, and the firm’s clearing and prime brokerage carry the cost of the margin they must fund.

Resolution: Title II Single Point of Entry at Home, the Bank of England’s Recognition and Internal MREL

How a US bank’s UK operations are meant to come apart, or not: the holding company’s single point of entry under Title II with the external TLAC absorbing the losses, the Bank of England’s recognition of the US resolution for the branch with its own powers in reserve, the designated firm’s internal MREL the Bank can write down and the support agreement behind it, the critical functions (the hub, the LCH memberships, the sterling clearing) that must keep running, the FSCS and the dually payable deposits behind the branch’s depositors, the crisis management group and the 165(d) plan where the Bank and the US agencies reconcile their plans, and the resolution liquidity and capital pre-positioned under RLAP, RLEN, RCAP and RCEN.

• The Banking Act and third-country resolutions: the Bank of England is the UK resolution authority with the stabilisation powers (transfer, bridge bank, bail-in, temporary public ownership) and the special resolution regime; for a third-country bank’s UK branch, the Act lets the Bank recognize and enforce the home resolution action (with the Treasury’s approval) or, where it refuses, take its own action on the UK branch; the PRA’s reliance on a branch’s home regime rests on the credibility of the home resolution strategy.
• Title II and the 165(d) plans: the Orderly Liquidation Authority of the Dodd-Frank Act lets the FDIC resolve a systemic financial company as receiver, with the single point of entry strategy (the holding company into receivership, the losses to its shareholders and TLAC holders, the operating subsidiaries recapitalized and kept open); the 165(d) resolution plans describe the strategy under the Bankruptcy Code and the group’s resources, with the support agreement that obliges the holding company to downstream capital and liquidity to the material entities, the London branch and the UK firm among them.
• Internal MREL and the UK subsidiary: the Bank of England sets internal MREL for the material UK subsidiaries of foreign G-SIBs at 75% to 90% of the external equivalent, met with capital and eligible liabilities issued to the group with a contractual trigger; the UK resolvability assessment framework applies in full to the large UK banks and in part, through the Bank’s expectations, to the designated firms of foreign groups; the US group’s RCAP and RCEN rules decide how much is pre-positioned.
• The FSCS, the FDIC and the London deposits: the FSCS covers the branch’s eligible deposits to GBP 120,000 and pays out in seven days in an insolvency; the FDIC does not insure a US bank’s foreign branch deposits, but since 2013 the US banks make their London deposits dually payable so that they rank as deposits (not as general claims) under the US depositor preference in a receivership of the bank, sharing pro rata with the FDIC’s subrogated claim; the PRA asked for it after the crisis and the FDIC’s rule allowed it.

The Reporting Calendar: the Branch, the Designated Firm, the Taxes and the Levies

The reporting calendar of a US bank’s UK operations: the daily transaction reports under UK EMIR, MiFIR and SFTR beside the CFTC’s and the FR 2052a at home, the monthly statistics, PRA110, COREP and FINREP of the firm with the FFIEC 030 for the branch at home, the semi-annual Branch Return and the annual ICAAP, ILAAP and plans, the UK taxes and levies (corporation tax and the bank surcharge on the attributed profit, the bank levy on the London balance sheet, the FSCS and PRA levies), the US side of the same tax with the foreign tax credit and the CFC rules, and the data behind the returns under the PRA’s data quality expectations.

• The Branch Return: the PRA’s semi-annual return for the UK branches of non-UK banks (since 2015), with the branch’s balance sheet, its funding, its deposits by type and the FSCS-covered amounts, its business lines and its reliance on the group; it is the PRA’s window on a branch it supervises on reliance, beside the Bank of England’s statistical forms the branch files monthly and the FCA’s conduct returns.
• The bank levy: a UK tax on the chargeable equity and liabilities of the banks’ UK balance sheets above GBP 20,000,000,000 (at 0.10% for the short-term and 0.05% for the long-term liabilities since 2021), applied to the UK operations of foreign banks (the branches and the subsidiaries together) as to the UK banks; the bank surcharge adds 3% to the corporation tax on the banking profits above GBP 100,000,000; both are levied on the US groups’ London operations.
• The US tax on the London profit: a foreign branch of a US bank is part of the same taxpayer, so the branch’s profit is in the bank’s US return with a credit for the UK tax paid; a foreign subsidiary like the UK firm is a controlled foreign corporation whose profits the 2017 tax reform taxes as earned under the GILTI rules with a partial credit; the transfer pricing between the branch, the firm and the US entities is documented for both tax authorities under the OECD guidelines.
• Regulatory reporting as a supervisory topic: the PRA’s 2021 letter on regulatory reporting found weak governance, controls and data at many firms and commissioned skilled person reviews under section 166; the designated firms of the foreign banks were among the firms reviewed, and the PRA expects a senior manager to own the reporting with a documented control framework and an attestation on the key returns.

The New York Line: Two Ledgers, the FFIEC 030, the Call Report and One Year-End

How a US bank’s London books reach New York: the daily close in US GAAP into the bank’s general ledger (the branch as a segment) and the holding company’s consolidation (the firm as a subsidiary), the two ledgers and the reconciliation between IFRS or UK GAAP and US GAAP, the monthly close with the FFIEC 030, the call report and the FR Y-9C, the CCAR and FR 2052a submissions built on the same data as the PRA’s stress tests, the December 31 year-end on both sides with two sets of accounts, the branch’s profit attribution and the group’s transfer pricing, and the UK and US views of the same books.

• The FFIEC 030: the Foreign Branch Report of Condition that the US banks file for each foreign branch (annually, and quarterly for the branches above the size thresholds), with the branch’s assets and liabilities, the claims on and due to the head office and the other offices, and the memoranda on the local business; the branch is consolidated in the bank’s call report (the FFIEC 031, with the schedules on the foreign offices) and the holding company’s FR Y-9C.
• Two accounting bases: the UK firm’s statutory accounts are prepared under IFRS or UK GAAP and audited by a UK auditor, the group reports under US GAAP; the differences (the expected credit losses under CECL at origination against IFRS 9’s stages, the hedge accounting, the fair value options, the leases) are reconciled in a bridge the auditors and the regulators read; a branch files no statutory accounts of its own, only the overseas company filings and the HMRC computation.
• Profit attribution: HMRC taxes the branch on the profit attributed under the authorized OECD approach, which treats the branch as a separate enterprise with the functions its people perform, the assets they manage and the risks they control, and attributes to it a notional free capital that limits the interest it can deduct on the head office funding; the IRS taxes the whole bank with a credit; the group’s transfer pricing study documents the split of the global books.
• One year-end: the US groups close on December 31 at home and in London, so the UK entities have one annual cycle where a Japanese bank’s London branch has March 31 for Tokyo and December 31 for the UK; the UK firm’s accounts are filed at Companies House within nine months and the group’s 10-K within 60 days, both audited, the London books inside the group’s under the PCAOB’s standards and the Sarbanes-Oxley controls.

Examinations: the PRA, the FCA, the OCC’s London Examiners and the College

The supervisory year of a US bank’s UK operations: the PRA’s periodic summary meeting and the Proactive Intervention Framework for the branch and the firm, the OCC’s examination of the London branch as part of the bank through its London examiners and the Fed’s of the group, the FCA’s supervision of conduct, markets and the client assets, the section 166 skilled person reviews and the findings reconciled with the OCC’s MRAs, the college, the crisis management group and the memoranda, and the UK accountability of the senior managers and the boards beside the US accountability of the bank’s officers.
