Level 1 flows of the EU market infrastructure: the key exchanges, clearing houses, depositories and payment systems of the euro area, one diagram per service, grouped by the institution that runs them (Euronext, Deutsche Börse, LCH SA, Euroclear, the Eurosystem’s platforms, EBA Clearing, the other venues, CLS). Each diagram follows an illustrative trade or payment through the service’s own cycle with the infrastructure at the center in purple, its members on one side, the clients behind them, the infrastructures it hands off to on the other, and the overseer; the strip above it is the profile (owner, what it handles, members, links, overseer, the clock). Columns are the parties, rows the phases; numbered steps are messages, deliveries, payments or reports between them, with the channel or system in the pill. Hover a step for the detail, click it or use the walkthrough to be taken through the diagram step by step. The institutions are the subject; the products they handle are on the sell-side, buy-side and other pages of this set, and the foreign bank pages show the same infrastructures from the user’s side. Euro area market conventions and EUR throughout; all numbers illustrative. New to this? Begin with Start here.

The Eurosystem’s own infrastructures, the four TARGET services the ECB and the national central banks own and four of them operate: four services on this page. T2, the euro’s real-time gross settlement system where every large payment and every infrastructure’s cash leg ends on an account at a national central bank; T2S, the settlement platform of 24 depositories where the securities and the cash settle together in central bank money; TIPS, the instant payment settlement in seconds around the clock that the 2024 regulation made the euro retail payment’s default layer; and ECMS, the single collateral system since June 2025 behind the monetary policy credit and T2’s intraday credit.
OwnerThe Eurosystem (the ECB and the national central banks of the euro area); T2 and T2S operated by the Banque de France, the Bundesbank, the Banca d’Italia and the Banco de España; TIPS by the Banca d’Italia; ECMS by the Banque de France and the Banco de España.
What it runsT2 (the RTGS and the central liquidity management, since March 2023), T2S (since June 2015), TIPS (since November 2018), ECMS (since June 2025); the Danish krone and the Swedish krona on the platforms beside the euro.
How a payment movesA high-value payment settles on the RTGS accounts at once; a securities delivery settles on T2S against the cash on the dedicated cash accounts; an instant payment settles on the TIPS accounts in seconds; the collateral in ECMS sets the credit line the RTGS draws on.

EURO1, the large-value net system whose single obligation structure makes each payment final as it is processed and settles the net once in T2; STEP2, the batch clearing house of the SEPA credit transfers and direct debits that carries the payroll, the pensions and the bills; and RT1, the first pan-European instant payment system, settling since the reachability measures on a TIPS account in central bank money.
OwnerEBA Clearing, owned by its user banks (the shareholders in Paris); founded in 1998 by the Euro Banking Association’s banks for the euro’s start.
What it runsEURO1 and STEP1 for the large-value and commercial payments, STEP2 for the SEPA batch, RT1 for the instant payments, the request-to-pay and the fraud services.
How a payment movesA commercial payment nets through EURO1 and settles in T2 at 16:00 CET; a payroll file goes through STEP2’s cycles and settles in T2 per cycle; an instant payment adjusts the RT1 positions on the TIPS technical account within seconds.
Overseen byThe ECB as lead overseer under the SIPS Regulation for EURO1 and STEP2 and as a prominent system for RT1; designated under the Settlement Finality Directive; the EPC for the SEPA schemes.
The venues the exchanges do not own: two services on this page. Cboe Europe, the pan-European equity MTF born of the competition MiFID opened in 2007, trading every exchange’s shares from Amsterdam since Brexit with its own clearing house, Cboe Clear Europe, the largest cash equity CCP in Europe netting the trades across 47 venues; and the bond and swap venues, the request-for-quote platforms and the interdealer OTFs rebuilt in Amsterdam and Paris after Brexit, where the swaps go to the CCP within seconds under the trading and clearing obligations and every trade is reported to the repositories, the APAs and the NCAs.
OwnerCboe Global Markets (listed in the US) for Cboe Europe and Cboe Clear Europe; Tradeweb (LSEG-controlled), Bloomberg, MarketAxess, TP ICAP, BGC and Tradition for the OTC venues; DTCC, Clearstream and KDPW for the trade repositories.

How a trade movesA French share matched on Cboe Europe clears at Cboe Clear Europe and settles at Euroclear France on T2S; a euro swap executed on Tradeweb EU goes to Eurex Clearing or LCH Ltd within seconds and to a trade repository by T+1; a corporate bond traded on MarketAxess NL settles through the custodians at the CSD.
Overseen byThe AFM for the Amsterdam venues and the AFM with DNB for Cboe Clear Europe; the AMF and the others for the OTFs; ESMA for the trade repositories, the obligations and the consolidated tapes; the home regulators of the stocks under MAR.
CLS, the bank the banks built in 2002 to remove the Herstatt risk, seen from the euro: one service on this page, the settlement day in which the euro legs of the world’s FX trades are paid in through T2 to an account at the ECB in the five-hour window of the European morning, settled against the dollars, the yen and the sterling payment versus payment on CLS’s own books and paid out again by noon, with the ECB in the oversight committee the Fed leads.
OwnerCLS Group Holdings, owned by about 70 settlement member banks; CLS Bank International, an Edge corporation under the Fed, operating since 2002 with the euro among the founding currencies.
What it runsThe payment-versus-payment settlement of FX spot, forwards and swaps in 18 currencies; CLSNet for the bilateral netting of the others; the same-day session; the FX data.
How a trade movesA euro FX trade submitted on T is netted into the pay-in schedule, the euro leg paid in through T2 to CLS’s account at the ECB in the window, settled against the other leg on CLS’s books both at once and paid out through T2 by noon.
Overseen byThe Federal Reserve as primary supervisor; the CLS Oversight Committee of the 18 central banks of issue with the ECB for the euro; designated under the Settlement Finality Directive.
How to read a diagram
Columns are the partiesThe investors on the left, then the members (the banks, investment firms and custodians that hold the membership), the infrastructure itself in the middle in purple (the service the diagram is about), the other participants (the market makers, the other side, the trade sources), the infrastructures it hands off to (the clearing house behind an exchange, the CSD and the Eurosystem behind a clearing house) and the overseer on the right.
Rows are the phasesTime runs down the page in the service’s own cycle: the opening auction to the close for an exchange, trade capture to netting to settlement for a clearing house, the night-time cycles to the end-of-day cash for a depository, the pay-ins to the pay-outs for CLS, the open to the close for T2. The band label gives the timing.
Arrows are stepsNumbered in order. Solid arrows are messages, deliveries or payments; dashed ones are standing flows like reports and oversight; two-headed ones are exchanged or matched. Boxes on the infrastructure’s own lifeline are what it does internally: a novation, a netting run, a settlement cycle.
Pills are the channelAmber for voice and chat, blue for electronic platforms and portals, rose for SWIFT and ISO 20022 messages, grey for infrastructure and regulatory systems (the matching engines, the clearing portals, the Eurosystem’s services, the repositories), teal for market data, lavender for the members’ internal systems. Each pill shows a one-line definition on hover.
The strip is the profileAbove each diagram the worked example strip gives the institution’s profile: who owns it, what it handles with illustrative volumes, who its members are, what it links to, who oversees it, and the clock of its cycle. Hovering a step shows the full detail; clicking it opens the walkthrough.
The grouping is by institutionThe area tabs are the groups that run the services (Euronext, Deutsche Börse, LCH SA, Euroclear, the Eurosystem’s platforms, EBA Clearing, the other venues, CLS) and the product tabs under each are the services with their own mechanics; the facts table below lists every service with the same five columns. The flags open the same chain for the other jurisdictions, where the institutions differ.
A flow 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.

Every diagram on this page is one link of this chain seen from inside: the venue that matches (a regulated market, an MTF, an OTF), the clearing house that novates and nets, the depository that settles against the cash on T2S, and the Eurosystem where the cash becomes final; the investment firm carries the investor through the chain as the member the investor is not, and the authorities read the record at each link. What the EU version shows is a market of many venues competing for the same shares under MiFID, of clearing choice and interoperability for the cash equities beside the exchanges’ own CCPs for the derivatives, of national depositories kept in name and settled on one Eurosystem platform, and of a central bank that runs the settlement layer and oversees the private systems beside it.
The flows, 24 of them
Each card opens its diagram. The tabs at the top do the same; the search box finds a flow by name, rule, report or keyword.
Who owns each service, what it handles, who its members are, what it links to, who oversees it
The same five questions for every service. The answers are what distinguish the EU infrastructure: listed exchange groups that own their clearing houses and depositories beside user-owned utilities and the central bank’s own platforms, clearing choice and interoperability for the cash equities beside the exchanges’ silos for the derivatives, national depositories settled on one Eurosystem platform, and a supervision split between the national authorities, ESMA’s colleges and the Eurosystem’s oversight.

Glossary
The terms that come back on every diagram. Every pill in the diagrams also shows its definition on hover.
Concepts, terms and rules
Regulated market: A trading venue authorized under MiFID II as an exchange (Euronext Paris, the Frankfurt Stock Exchange, Euronext Amsterdam, the Borsa Italiana markets): the admission to trading of the listed securities, the market abuse surveillance, the transparency; the MTFs and OTFs are the other two kinds of venue.
MTF: A multilateral trading facility under MiFID II: a venue run by an investment firm or market operator under lighter rules than a regulated market; Cboe Europe, Aquis and Turquoise for equities, Tradeweb and MarketAxess for bonds, the dark MTFs under the double volume cap.
OTF: An organised trading facility: the MiFID II venue category for non-equities where the operator has discretion in matching (voice and hybrid broking in bonds and derivatives).
Share trading obligation: MiFIR’s rule that an investment firm trades shares admitted to trading on a regulated market on a regulated market, an MTF, a systematic internalizer or an equivalent third-country venue, with exemptions for non-systematic and large trades; narrowed to EEA shares by the 2024 review.
Derivatives trading obligation: MiFIR’s requirement that the derivatives subject to the clearing obligation and sufficiently liquid (the euro, dollar and sterling fixed-to-float swaps in the benchmark tenors, the overnight index swaps, the iTraxx indexes) be executed on a regulated market, an MTF, an OTF or an equivalent third-country venue.
Clearing obligation: EMIR’s requirement that the standardized OTC derivatives ESMA designates (the interest rate swaps in the main currencies, the iTraxx Europe and Crossover indexes) be cleared at an authorized or recognized CCP by the financial counterparties and the large non-financial ones.
Active account requirement: EMIR 3.0’s requirement (2024) that firms subject to the clearing obligation keep an active account at an EU CCP for euro and Polish zloty interest rate swaps and euro short-term rate futures, to move clearing from London.
Clearing choice: The arrangement under which a trading venue lets its members choose among interoperable CCPs for the cash equities (Euronext Clearing or Cboe Clear Europe on Euronext, Eurex Clearing or Cboe Clear Europe on Xetra since October 2024), the CCPs margining each other for the trades between their members; the derivatives have no choice.
Interoperability: The link between two CCPs under which a trade between a member of each is cleared by both, each facing its own member and the two CCPs facing each other with margin between them; the EU cash equity market runs on it (Cboe Clear Europe, LCH SA, SIX x-clear, Euronext Clearing) and the Italian bonds between Euronext Clearing and LCH SA.
Opening and closing auctions: The single-price auctions that open and close the equity exchanges’ day: the on-open and on-close orders and the continuous book are matched at the price that maximizes the volume, with the imbalance published in advance; the closing auction sets the official close the funds are valued at and trades the index rebalances.
Designated sponsor: The bank or trading firm an issuer mandates to quote its shares on Xetra under the exchange’s minimum requirements (the spread, the size, the presence), rated quarterly; the German model of liquidity provision for the mid and small caps, which a Prime Standard mid cap needs for the MDAX and SDAX.
Liquidity provider: A market maker quoting a venue’s instruments under a program with a maximum spread, a minimum size and a presence time against rebated fees (Euronext’s single-stock and global liquidity providers, the ETF market makers), under MiFID II’s market making agreements.
Periodic auction: A frequent batch auction (Cboe Europe’s every 100 milliseconds) matching the orders at one price inside a short call phase, treated as lit trading; the venues built them after MiFID II’s volume caps limited the dark trading in 2018, and ESMA reviews them as a market structure of their own.
Volume cap: The limit on dark trading under the reference price and negotiated trade waivers: a double cap of 4% per venue and 8% EU-wide until the 2024 MiFIR review, a single EU-wide cap of 7% per share since, above which the waiver is suspended for six months.
Novation: The legal step by which one trade between two parties becomes two trades with the clearing house in the middle.
Netting: Offsetting all of a firm’s buys and sells of the same thing into one net delivery or payment.
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.
Default fund: The prefunded contributions of a CCP’s clearing members, in proportion to their risk, that stand behind the margin in the default waterfall after the defaulter’s own resources, sized under EMIR to cover the default of the two largest members under stress (cover two); the EU name for the clearing or guarantee fund.
Default waterfall: The order in which a clearing house absorbs a defaulting member’s losses: the defaulter’s margin and fund contribution, the clearing house’s own contribution, the surviving members’ fund, the assessments on the members, then the recovery tools.
Cover two: The standard for the systemically important clearing houses: prefunded resources sufficient to cover the default of the two members (with their affiliates) that would cause the largest losses under extreme but plausible stress; cover one for the others.
Skin in the game: The clearing house’s own capital placed in the default waterfall ahead of the surviving members’ contributions, the subject of the standing argument between the CCPs and their members on how much it should be.
Prisma: Eurex Clearing’s portfolio-based margin model (2013): a filtered historical simulation across the correlated contracts in a liquidation group with the stress scenarios, the liquidity and concentration add-ons and the cross-margining between the listed and the OTC positions; the counterpart of CME’s SPAN 2 and OCC’s STANS.
Jump-to-default risk: The margin component of a CDS clearing house for the loss if a reference entity defaults tomorrow, net of the recovery, charged on top of the spread risk; the risk the futures models do not have.
Price alignment: The interest paid or received on the cumulative variation margin of a cleared swap at the overnight rate, so that the daily settlement of the variation margin leaves the cleared swap priced like a collateralized bilateral one.
Settled-to-market: The treatment of a cleared swap’s daily variation margin as a settlement that resets the swap’s value to zero rather than as collateral, which changes its accounting and the leverage ratio treatment; the standard at CME and LCH.
Client segregation: EMIR Article 39’s requirement that a clearing member offer its clients the choice between an omnibus client account (the clients’ positions and collateral together, separated from the member’s own) and an individually segregated account at the CCP, so that in the member’s default the clients’ positions port to another member with their collateral.
Sponsored clearing: A clearing member bringing its clients’ trades into the clearing house under its own membership; at FICC, the netting member sponsors money funds, hedge funds and asset managers into the CCP, submits their Treasury and repo trades, guarantees their performance and margins them.
ISA Direct: Eurex Clearing’s model (2016) under which a buy-side firm becomes a direct clearing member with a clearing agent (a bank) providing the default fund contribution and the default management obligations, so that the client’s positions and collateral are its own at the CCP; the EU counterpart of FICC’s sponsored service.
Delivery versus payment: A settlement in which the securities are delivered only if the payment is made and the payment made only if the securities are delivered, removing the principal risk; model 1 settles both gross and simultaneously (Fedwire Securities), model 2 the securities gross and the cash net (DTC).
Payment versus payment: A settlement in which the two currency legs of an FX trade are settled together or not at all, removing the Herstatt risk; CLS’s mechanism across its accounts at the central banks.
Herstatt risk: The settlement risk of paying one currency of an FX trade before receiving the other, named for Bankhaus Herstatt, closed in June 1974 after receiving its Deutsche mark legs and before paying its dollar legs; the risk CLS was built to remove.
Commercial bank money: A claim on a commercial bank: the cash accounts the participants hold with an ICSD (Euroclear Bank, Clearstream Banking Luxembourg) on which the Eurobond settlement is made, carrying the bank’s credit; CSDR regulates the ICSDs as banking-type CSDs for it.
Central bank money: A claim on the central bank: the balances on the T2 main cash accounts and the T2S and TIPS dedicated cash accounts on which the RTGS payments, the T2S settlements and the instant payments are final, with no credit risk; the Eurosystem’s policy prefers it for the systemically important settlements.
Night-time settlement: T2S’s two settlement cycles from 20:00 CET on the day before the settlement date, in which the matched instructions settle in sequences (the corporate actions, the CCPs’ positions, the deliveries) against the funded dedicated cash accounts and the auto-collateralization, so that most of the volume settles before the European morning.
Auto-collateralization: T2S’s intraday credit from the central bank (or from a payment bank to its client) granted automatically to a participant whose dedicated cash account is short, secured on the securities it is receiving (on flow) or holds (on stock) and reversed when the cash arrives; the feature that lets T2S settle gross without the gross liquidity.
Dedicated cash account: The central bank money account in T2 that a CSD participant uses on T2S for the cash legs of its settlements, in its own name or through a payment bank; funded from the participant’s T2 account.
Main cash account: The account each bank holds at its national central bank in T2’s central liquidity management module, where the reserves sit, the intraday credit line is attached and the liquidity is moved from to the RTGS, T2S and TIPS dedicated cash accounts; one per bank since the 2023 consolidation.
Central liquidity management: The T2 module (2023) through which a bank manages its central bank liquidity from one main cash account across the RTGS, the T2S and the TIPS dedicated cash accounts, with the liquidity transfers, the floor and ceiling rules and the end-of-day sweeps.
Intraday credit: The credit the Eurosystem extends to a bank during the day on its main cash account, free and unlimited within the collateral it has pledged (now through ECMS), to be repaid by the close or turned into marginal lending at the penalty rate; the counterpart of the Fed’s daylight overdraft, collateralized.
Single obligation structure: EURO1’s legal design under German law in which each participant has at every moment one claim on or obligation to the system as a whole, adjusted as each payment is processed, so that the payments are final when processed with no bilateral claims to unwind; the model for a net system with finality.
Settlement finality: The moment a transfer order can no longer be revoked, by the system’s rules under the Settlement Finality Directive’s protection against the insolvency of a participant: on processing in T2, EURO1 and TIPS, on the settlement in T2S, on the ICSD’s books for the Eurobonds, on CLS’s books for the FX legs.
Real-time gross settlement: A payment system that settles each payment individually and finally in central bank money as it arrives, with no netting and no settlement risk between the participants (Fedwire, T2, CHAPS, Lynx), at the cost of the liquidity each payment needs.
T+1: The settlement cycle of the US securities market since May 28, 2024 (Canada and Mexico the day before), one business day after the trade, which halved the margin NSCC holds and set the 21:00 ET affirmation deadline on the trade date; the UK and the EU follow in October 2027.
Settlement discipline: CSDR’s rules on fails: the allocation and confirmation deadlines for institutional trades, the matching and the T2S functions that reduce fails, the cash penalties on every failing instruction, the reporting of settlement efficiency; the mandatory buy-in was suspended and then removed.
Dematerialization: The replacement of the paper certificates by book entries in the CSD under the national laws (France 1984, Italy 1998, Germany’s electronic securities act of 2021 beside the global certificates), so that a security exists only as a position in the depository and ownership moves by book entry.
Direct holding: The Nordic model in which the beneficial owner holds its securities in an account in its own name in the CSD’s register (Euronext Securities Copenhagen and Oslo, Euroclear Finland and Sweden), rather than behind a nominee or an intermediary; the issuer sees its holders, and the CSD runs the shareholder register.
The bridge: The electronic link between Euroclear Bank and Clearstream Banking Luxembourg (1980, automated in 1993, hourly since) through which a Eurobond held in one ICSD is delivered against payment to a participant of the other, the two ICSDs keeping accounts with each other; it makes the Eurobond market one market in two systems.
Collateral pool: The set of securities and credit claims a counterparty has mobilized to its national central bank, against the whole of which the Eurosystem’s credit (the refinancing operations, the marginal lending, the intraday credit line) is secured; one pool per counterparty in ECMS, substituted freely and margin-called on its total.
Eligible assets: The securities and credit claims the Eurosystem accepts as collateral under the Governing Council’s collateral framework (the General Documentation): the marketable assets on the list the ECB publishes daily and the credit claims meeting the credit quality thresholds, each with its haircut by class, maturity and rating step.
Quote-driven market: A market run on the market makers’ firm two-way quotes rather than on an order book of anonymous orders, with the takers hitting the quotes (MTS for the euro government bonds, BrokerTec in the US); the makers’ obligations are enforced by the issuers through the primary dealer system.
Primary dealer system: The designation by a euro area Treasury (the Italian Treasury, the Agence France Trésor, the Belgian Debt Agency, the Spanish Tesoro) of the banks obliged to bid at its auctions and to quote its bonds on the electronic market it recognizes, ranked on the quoting and the auction participation and rewarded with the syndication mandates; MTS built its national markets on these specifications.
Cheapest to deliver: The deliverable bond in a Bund, Bobl or Schatz future’s basket that is cheapest for the short to deliver after the conversion factor against the 6% notional, which the future tracks and the basis trade between the future and the cash bond is built on.
Credit event: The failure to pay, the bankruptcy or the restructuring of a reference entity under the ISDA 2014 definitions, ruled by the regional determinations committee, after which the auction sets the recovery price and the CDS contracts settle to it; the cleared contracts settle in cash at the CCP.
Request to pay: The EPC’s SEPA request-to-pay scheme (2021) under which a payee sends a payment request with the amount and the reference to the payer’s bank app, which the payer approves and pays by an instant credit transfer; the European answer to the card at the point of sale and the bank-owned Wero wallet builds on it.
Verification of payee: The check of the payee’s name against the IBAN before a credit transfer is executed, mandatory for the euro-area PSPs since October 9, 2025 under the Instant Payments Regulation, which warns the payer of a mismatch and cuts the misdirected and fraudulent transfers.
Composite price: A reference price for a bond built from the recent trades (TRACE), the quotes and a model, published by the platforms (MarketAxess’s CP+) and the data vendors, which the request-for-quote responses are judged against.
Reports, tapes and data
EMIR Refit reporting: The April 29, 2024 rewrite of the EMIR trade reporting: the ISO 20022 XML messages, 203 fields, the global UTI and UPI and the critical data elements, the mandatory delegation rules, the reconciliation of the two counterparties’ reports and the error notifications, reported to a registered trade repository by T+1 with the valuations and the collateral daily.

MT306: The Swift confirmation of the FX options the MT305 cannot describe: average rate (Asian) options and forwards, barriers, digitals and other exotic structures, with their averaging or observation dates.
MT380: The Swift FX order: an investment manager instructs its custodian to buy or sell a currency for a fund; the custodian confirms the execution with an MT381.
MT606: The Swift precious metal debit advice: the account keeper tells the account owner its metal account was debited, with the bar list when the metal moves into allocated bars.
MT607: The Swift precious metal credit advice: the account keeper tells the account owner its metal account was credited, in fine troy ounces.
MT608: The Swift statement of a metal account: the opening and closing balances in ounces and the movements of the period, or the bars held in an allocated account.
The Euronext Cash Markets: the Opening Auction, the Order Book on Optiq, the Liquidity Providers, the Close and the Trade to the CCP
The Euronext cash markets’ day: the pre-opening and the opening auction at 09:00 CET on Optiq’s single order book, the continuous trading with the fee grid, the MTF competition and the volume cap, the liquidity providers’ obligations and rebates, the closing auction at 17:30 that sets the reference prices and the indexes, the trade to Euronext Clearing or Cboe Clear Europe under interoperability and to the seven countries’ CSDs on T2S at T+2, the listing on the regulated markets and the Growth and Access MTFs under the Listing Act, and the seven national regulators in the college under ESMA’s rules.
Worked example, illustrative:owner Euronext N.V., listed in Paris; the merger of the Paris, Amsterdam and Brussels exchanges in 2000, Lisbon 2002, Dublin 2018, Oslo 2019, Milan 2021handles listing and trading of the equities, ETFs, funds and bonds of seven markets; 1,500 listed companies; EUR 10,000,000,000 a day, illustrativemembers the member banks, brokers and proprietary firms; the retail brokers through them; the liquidity providerslinks Euronext Clearing as the preferred CCP and Cboe Clear Europe under interoperability; Euroclear’s ESES, Euronext Securities and Euroclear Bank for settlement on T2Soverseen by the seven national regulators (the AMF, the AFM, the FSMA, the CMVM, the Central Bank of Ireland, Finanstilsynet, Consob) in the Euronext college; ESMA for the rulesthe day pre-opening from 07:15 CET; opening auction 09:00; continuous to 17:30; closing auction 17:35; trading at last to 17:40; settlement T+2

Seven exchanges, one book: a share listed in Paris trades on the same engine as one listed in Milan, the members of every market see it, and the two auctions a day fix the prices Europe’s funds are valued at. The trade then goes to the group’s own clearing house and to the CSD of the country the company listed in.
Optiq: Euronext’s trading platform since 2018, running one order book per security for the seven cash markets and the derivatives markets from one data center; the members connect through the Optiq order entry gateway and the market data gateway, and the same engine serves Oslo and Milan since their acquisitions; the matching is by price, time and the auction algorithm.
The liquidity provider programs: MiFID II requires a market making agreement between a venue and any firm pursuing a market making strategy, and the exchanges turned it into programs: Euronext’s single-stock liquidity provider (a bank sponsored by the issuer to quote a mid cap), the global liquidity providers across the blue chips and the ETF market makers, each with a maximum spread, a minimum size and a presence time against rebated fees.
Clearing choice: a Euronext cash trade clears at Euronext Clearing, the group’s preferred CCP since the November 2023 migration from LCH SA, or at Cboe Clear Europe under the interoperability arrangement, the member choosing its CCP; the two CCPs margin each other for the trades between their members; the derivatives have no choice and clear at Euronext Clearing alone.
T+2 and T+1: the EU settles securities on T+2 under CSDR since 2014 and moves to T+1 on October 11, 2027 under the 2025 amendment, on the same day as the UK and Switzerland; the settlement discipline regime’s cash penalties on the fails apply since February 2022, and the mandatory buy-ins were shelved.
Euronext Derivatives: the CAC 40 and AEX Contracts, the Single Stock Options and the Milling Wheat From the Order to the Expiry
Euronext’s derivatives markets: an order in a CAC 40 future, an AEX option or a milling wheat contract through the members to the Optiq derivatives book, the match against the book and the market makers’ quotes with the strategies and the block trades, the novation at Euronext Clearing with the VaR margin and the segregated client accounts since the 2024 migration from LCH SA, the daily settlement prices and the variation margin, the expiry in cash on the index, by delivery of the stock through the CSD or of the wheat into the silos, and the AMF, the AFM, ESMA’s position limits and the CCP’s college.
Worked example, illustrative:owner Euronext N.V.; the Paris MATIF and MONEP (1986, 1987) and the Amsterdam options exchange (1978) merged into Euronext in 2000; Euronext Clearing since 2024handles the CAC 40, AEX, BEL 20 and PSI futures and options, 400 single stock option classes, the milling wheat, rapeseed and corn; 500,000 contracts a day, illustrativemembers the member banks and brokers; the clearing members of Euronext Clearing; the options market makers; the clients and the grain trade behind themlinks Euronext Clearing for every contract; the cash markets for the index values and the stock delivery; the CSDs for the exercised stock; the approved silos for the wheatoverseen by the AMF for Paris and the AFM for Amsterdam as regulated markets; ESMA’s position limits; the CCP’s collegethe day index contracts 08:00 to 22:00 CET; stock options to 17:30; wheat 10:45 to 18:30; settlement prices at the close; margin the next morning; expiry the third Friday

The CAC 40 future, the AEX option and the European wheat contract trade on one book and clear at the group’s own clearing house, with the index expiries settled in cash against the auction prices and the wheat delivered into the silos of Rouen. The retail options market of Amsterdam is what makes it different from Eurex.
The Amsterdam options market: the European Options Exchange of 1978 was the first options exchange in Europe and made the Dutch retail investor an options trader; it became part of Euronext in 2000 and its single stock and AEX options are the largest retail options market on the continent, with market makers (the Amsterdam trading firms that grew into the global electronic market makers) quoting under obligations.
The milling wheat contract: the Euronext No. 2 milling wheat future (50 tonnes, delivery into the approved silos of Rouen, Dunkirk and the other ports) is the European price reference for wheat, used by the farmers’ cooperatives, the millers and the exporters to hedge and by the funds to trade the harvest; the position limits under MiFID II and the delivery rules keep the physical market and the contract aligned.
The migration from LCH SA: Euronext’s derivatives cleared at LCH SA (the former Clearnet, once Euronext’s own) until 2024; the group bought CC&G with Borsa Italiana in 2021, renamed it Euronext Clearing and moved the cash markets in November 2023, the commodities in July 2024 and the financial derivatives in September 2024, ending the long dependence on LCH and bringing the clearing revenue into the group.
The index expiries: the CAC 40 contracts settle on the third Friday against an expiry value computed from the component prices in the cash market (the monthly expiry at 16:00 from the auction prices, with the daily and weekly expiries beside), the AEX against the close; the settlement into the cash auction is the moment the two markets meet and the volumes spike.
Euronext›Euronext Clearing
Euronext Clearing: Trade Capture From the Euronext Markets and MTS, the VaR Margin, Netting and Settlement on T2S, the Default Fund
The former CC&G in Rome as the CCP of the group: the trades captured from the seven cash markets under clearing choice, from the derivatives markets and from MTS for the Italian government bond cash and repo, the novation at capture, the initial margin from the VaR model called through T2 and the CSDs with the segregated client accounts, the overnight netting into one position per ISIN per settlement date, the delivery-versus-payment settlement on T2S through the seven countries’ CSDs with the cash in central bank money, the default funds per asset class with the cover-two sizing, the waterfall and the auction, and the Banca d’Italia, Consob, the EMIR college and ESMA.
Worked example, illustrative:owner Euronext N.V.; the Cassa di Compensazione e Garanzia of 1992, acquired with Borsa Italiana in 2021 and renamed; the migrations from LCH SA in 2023 and 2024handles the Euronext cash markets under clearing choice, every Euronext derivatives contract, the Italian government bond cash and repo; EUR 15,000,000,000 of cash trades, 500,000 contracts and EUR 100,000,000,000 of repo a day, illustrativemembers the general clearing members (banks) carrying the trading members and the clients; the individual clearing members for their own tradeslinks Euronext Securities Milan and the other CSDs on T2S for the settlement; T2 through the Banca d’Italia for the cash and the margin; Cboe Clear Europe under interoperability for the cash marketsoverseen by the Banca d’Italia and Consob under EMIR; the college with the markets’ and CSDs’ authorities, the Eurosystem and ESMA; recognized in the UKthe cycle capture through the day; margin by the morning deadline through T2; netting overnight; settlement on T+2 on T2S; the derivatives marked daily

The Italian clearing house became the clearing house of the whole group: every Euronext trade that is not sent to Cboe Clear Europe, every derivatives contract and the Italian repo novate in Rome, are margined on a VaR model and net into one position per ISIN that settles through seven countries’ CSDs on T2S. The default fund is sized for two members at once.
CC&G: the Cassa di Compensazione e Garanzia was created in 1992 as the clearing house of the Italian derivatives market and became the CCP of the Italian equities, government bonds and repo; Borsa Italiana owned it from 2000 and LSEG from 2007, and Euronext bought the Borsa Italiana group in 2021 for EUR 4,400,000,000 with the CCP and Monte Titoli as the prize that let it clear and settle its own markets.
The EMIR college: a CCP authorized in the EU is supervised by its national competent authority with a college of the authorities of the markets it serves, the CSDs it uses, the central banks of issue of the currencies it clears and ESMA; the college gives opinions on the authorization, the model changes and the extensions of service, and ESMA’s CCP Supervisory Committee (2020) coordinates the supervision of the EU CCPs and supervises the third-country ones.
Cover two: EMIR requires a CCP to hold prefunded resources (the margin, the default fund, its own contribution) sufficient to cover the default of the two clearing members to which it has the largest exposures under extreme but plausible conditions; the default fund is sized to the stress test results and recalculated monthly, with the CCP’s skin in the game at 25% of its capital placed before the survivors’ contributions.
The CCP Recovery and Resolution Regulation: the EU regime of 2021 (applicable from 2022) requires each CCP to keep a recovery plan with the tools beyond the waterfall (the cash calls, the variation margin gains haircutting, the tear-up) and gives the resolution authority (the Banca d’Italia for Euronext Clearing) the powers to resolve a failing CCP; the counterpart of the UK’s 2023 regime and of the US Title II for the CCPs.
Euronext›Euronext Securities
Euronext Securities: the Four CSDs, Instructions and Settlement on T2S, the Cross-CSD Links and the Asset Services
The depositories of the Euronext group: the securities of Italy, Denmark, Norway and Portugal held in book entry, the instructions for T+2 from the CCPs’ net positions, the custodians’ DVP and the free deliveries, the settlement on T2S in the night-time cycles and the real-time day with the cash on the dedicated cash accounts in central bank money and Oslo on its own platform, the cross-border settlement across the CSD links and the ICSDs’ omnibus accounts, the asset services for the coupons, the dividends, the corporate actions and the issuers, and the CSDR authorities with the central banks behind.
Worked example, illustrative:owner Euronext N.V.; Monte Titoli (1978) with Borsa Italiana in 2021, VP Securities (1980) in 2020, VPS (1985) with Oslo Børs in 2019, Interbolsa with Euronext Lisbon in 2002handles book-entry custody and settlement of the Italian, Danish, Norwegian and Portuguese securities; EUR 7,000,000,000,000 under custody across the four, 150,000 settlements a day, illustrativemembers the participant banks, brokers and custodians; the CCPs; the issuers and the holders behind themlinks T2S for Milan, Copenhagen and Porto; the dedicated cash accounts at the Banca d’Italia, Danmarks Nationalbank and the Banco de Portugal; the links to Euroclear Bank, Clearstream and the other CSDsoverseen by Consob and the Banca d’Italia, the Danish and Norwegian Finanstilsynet, the CMVM under CSDR; the central banks and the Eurosystem for T2Sthe day instructions matched through the day; night-time settlement from 20:00 CET; real time 05:00 to 16:00 DVP cutoff; settlement T+2; the asset services daily

Four national depositories on one balance sheet: the Italian debt stock at Milan is the largest line, three of the four settle on T2S in central bank money and Oslo on its own, and the links to Euroclear and Clearstream are where the foreign holders of the BTPs come in. The coupons and the corporate actions ride the same accounts.
T2S outsourcing: a CSD on T2S keeps its participants, its accounts and its asset services but runs the settlement on the Eurosystem’s platform, where the securities accounts it opens and the participants’ dedicated cash accounts at the central bank are matched and settled together; Monte Titoli joined in the first wave of June 2015, Interbolsa in March 2016, VP in September 2016 for the euro and October 2018 for the krone; the Norwegian CSD is outside the platform.
Dematerialization: the Italian securities are dematerialized by law since 1998 (the Monte Titoli account is the security), the Danish since 1983 and the Norwegian since 1985 with the investors’ own accounts in the CSD (the Nordic direct holding model, where the beneficial owner is named in the register rather than behind a nominee), the Portuguese under the 1999 code; the direct holding model is why the Nordic CSDs run the shareholder registers and the issuers see their holders.
The Italian government bond settlement: the BTPs, BOTs and CCTs settle at Milan after clearing at Euronext Clearing or LCH SA (RepoClear SA), with the primary dealers’ auction purchases settled against the Treasury’s account at the Banca d’Italia; a large share of the stock is held by the foreign investors through Euroclear Bank’s and Clearstream’s accounts, so the ICSD links are the busiest in the system.
SRD II: the revised Shareholder Rights Directive (2020) requires the CSDs and the intermediaries to pass the shareholder identification requests and the general meeting information down the chain and the votes up within set deadlines, on ISO 20022 messages, which turned the issuer services of the CSDs into a regulated process; the Nordic registers already knew their holders.
MTS: the Interdealer Euro Government Bond Market, the Quote-Driven Book, BondVision, MTS Repo and the Trade to the CCP
The interdealer market of the euro government bonds: the primary dealers’ firm two-way quotes under the Treasuries’ specifications on the national MTS markets, the anonymous hit on the quote-driven book that makes the trade, the dealer-to-client RFQ on BondVision beside the interdealer screen, the Italian repo market and the general collateral on MTS Repo, the trade to Euronext Clearing or LCH SA under their interoperability and to the CSDs on T2S, and Consob, the Banca d’Italia and the Treasuries’ specifications behind the obligations.
Worked example, illustrative:owner Euronext N.V. since the Borsa Italiana acquisition of 2021; founded by the Italian Treasury in 1988, privatized in 1997, LSEG-owned from 2007handles euro government bond cash trading on the national MTS markets, the dealer-to-client RFQ on BondVision, the Italian repo on MTS Repo; EUR 20,000,000,000 of cash and EUR 150,000,000,000 of repo a day, illustrativemembers the primary dealers and market makers as quoting members; the other dealers as price takers; the investors and the Treasuries on BondVisionlinks Euronext Clearing and LCH SA (RepoClear SA) as the CCPs under interoperability; Euronext Securities Milan, Euroclear France, Iberclear and the other CSDs on T2S; the Treasuries’ quoting statisticsoverseen by Consob and the Banca d’Italia for the Italian regulated market; the AMF, the FSMA and the others for the national MTFs; the Treasuries through the primary dealer specificationsthe day quotes from 08:15 CET; the cash market to 17:30; MTS Repo from 07:30; settlement T+2 for the cash; the repo on its dates

The dealers’ own screen for the government bonds: the makers show firm prices because the Treasuries rank them on it, the takers hit anonymously, the clients see it only through BondVision, and the Italian repo behind it is the largest cleared repo market in the euro area. Every trade goes to one of two interoperable CCPs and settles on T2S.
The quote-driven market: unlike the equity order books, the interdealer government bond markets (MTS in Europe, BrokerTec in the US) run on the market makers’ firm quotes, with the takers hitting them anonymously and the makers’ obligations enforced by the issuers through the primary dealer system; the makers’ quoting statistics (the presence, the spread, the size) decide the dealers’ ranking, the syndication mandates and the auction privileges.
The primary dealer specifications: each euro area Treasury (the Italian Treasury since 1988, the Agence France Trésor, the Belgian Debt Agency, the Spanish Tesoro) designates its primary dealers or specialists with the obligation to bid at the auctions and to quote the bonds on the electronic market it recognizes, and ranks them on the quoting and the auction participation; MTS built its national markets on these specifications, and the Treasuries read the data it sends them.
The CCP interoperability for the bonds: Euronext Clearing (CC&G) and LCH SA have cleared the Italian government bond cash and repo trades under an interoperability arrangement since 2003, each CCP’s members facing their own CCP and the two CCPs facing each other with margin between them; it is the only interoperable clearing of bonds in Europe, and the Italian repo market depends on it.
The Italian repo market: the dealers and the banks fund their BTP inventories and lend cash on MTS Repo, in special repo on a named bond (where a bond in demand trades below the general collateral rate) and in general collateral baskets, cleared and netted with the cash trades; the market’s size (the Italian debt stock is the largest in Europe) and its central clearing are why the Italian bonds are the collateral of the euro money market beside the Bunds.
Xetra: the Opening Auction on T7, the Order Book, the Designated Sponsors and the Floor, the DAX Close and the Trade to Eurex Clearing and CBF
The Frankfurt order book’s day: the pre-trading and the opening auction at 09:00 CET on T7, the continuous trading with the volatility interruptions and the midpoint books, the designated sponsors quoting the mid caps and the Frankfurt floor specialists quoting until 22:00, the closing auction at 17:30 that fixes the DAX close, the trade to Eurex Clearing or Cboe Clear Europe under clearing choice and the settlement at Clearstream Banking Frankfurt on T2S at T+2, the listing on the Prime Standard, Scale and the ETF segment, and the Hesse exchange authority, the trading surveillance office and BaFin.
Worked example, illustrative:owner Deutsche Börse AG, listed in Frankfurt; the Frankfurt Stock Exchange (1585) as a public-law institution it operates; Xetra since 1997, on T7 since 2017handles trading of the German and international shares, 2,000 ETFs and ETPs, funds and bonds; the DAX, MDAX and SDAX; EUR 6,000,000,000 a day, illustrativemembers the admitted trading members (banks, brokers, proprietary firms); the retail brokers through them; the designated sponsors and the floor specialistslinks Eurex Clearing and Cboe Clear Europe under clearing choice; Clearstream Banking Frankfurt on T2S with the cash at the Bundesbank; STOXX for the indexesoverseen by the exchange supervisory authority of Hesse and the Trading Surveillance Office; BaFin for the market abuse and the venue rules; ESMA’s standardsthe day pre-trading from 07:30 CET; opening auction 09:00; intraday auction 13:00; closing auction 17:30 to 17:35; the floor 08:00 to 22:00; settlement T+2

The German shares trade on the group’s own engine, clear at the group’s own clearing house (or at Cboe Clear Europe since 2024) and settle at the group’s own depository on T2S: a vertical chain under a state supervisor, with the designated sponsors quoting the mid caps and the floor specialists serving the retail investor until ten at night.
T7: Deutsche Börse’s trading architecture, built for Eurex in 2013 and extended to Xetra and the Frankfurt floor in 2017, with the same order entry, market data and matching for the cash and the derivatives markets; the group licenses it to other exchanges (the Vienna, Prague, Budapest and Ljubljana exchanges, the Bombay Stock Exchange), the way Nasdaq licenses INET.
The designated sponsors: the German model of liquidity provision for the mid and small caps, where the issuer mandates one or two banks or trading firms to quote its shares under the exchange’s minimum requirements (the spread, the size, the presence), rated AA to C each quarter and published; a Prime Standard mid cap needs a sponsor to be in the MDAX and SDAX selection; the DAX shares trade without one.
The Frankfurt floor: Börse Frankfurt is the second trading venue of the Frankfurt Stock Exchange, the successor of the floor trading, where specialists (the former lead brokers) quote every listed security continuously from 08:00 to 22:00 for the retail investors’ orders on T7, with the quotes referenced to Xetra during its hours; the regional exchanges (Stuttgart, Munich, Düsseldorf, Hamburg and Hanover, Berlin) run the same specialist model for the retail flow.
Clearing choice at Deutsche Börse: Xetra trades cleared at Eurex Clearing alone until October 2024, when Deutsche Börse opened the market to Cboe Clear Europe under an interoperability arrangement after years of the members’ requests, aligning Frankfurt with the clearing choice of Euronext, the LSE and the MTFs; the derivatives and the repo stay at Eurex Clearing alone.
Eurex: the Bund Future, the Euro Stoxx 50 Contracts and the €STR Futures From the Order to the Delivery, With Eurex Repo and GC Pooling
The Eurex day: an order in a Bund future, a Euro Stoxx 50 option or a €STR future through the members to T7, the match against the book and the market makers with the strategies and the block trades, the novation at Eurex Clearing with the Prisma margin called by 08:00 CET, the daily settlement prices and the variation margin, the expiry with the Bund delivery through Clearstream against the cheapest to deliver, the index contracts in cash and the stock options in stock, the cleared euro repo market on Eurex Repo and GC Pooling, and the Hesse exchange authority, BaFin, ESMA and the Bundesbank.
Worked example, illustrative:owner Deutsche Börse AG; Eurex formed in 1998 from the Deutsche Terminbörse (1990) and the Swiss SOFFEX, wholly owned since 2012; Eurex Repo since 2001handles the Bund, Bobl, Schatz and Buxl futures and options, the Euro Stoxx 50 and DAX contracts, the €STR and Euribor futures, 1,000 single stock option classes, the dividend and volatility derivatives; 8,000,000 contracts a day, illustrativemembers the admitted members (banks, brokers, proprietary firms) from Europe, the US and Asia; the clearing members of Eurex Clearing; the market makerslinks Eurex Clearing for every contract and the repo; Clearstream Banking Frankfurt on T2S for the Bund deliveries and the collateral; STOXX for the index values; the members’ T2 accounts for the marginoverseen by the exchange supervisory authority of Hesse and the Trading Surveillance Office; BaFin; ESMA’s standards and position limits; the CFTC as a foreign board of tradethe day trading 01:10 to 22:00 CET; settlement prices 17:15 and 17:30; margin by 08:00 the next morning; the Bund delivery on the tenth of the quarter month; the index expiry the third Friday

The Bund future prices the euro curve, the Euro Stoxx 50 contracts hedge the continent’s equity books, and every one of them clears at the group’s own clearing house and delivers through the group’s own depository. The cleared euro repo market sits beside it on the same membership.
The Bund future: the Euro-Bund future (EUR 100,000 of a notional 6% German government bond with 8.5 to 10.5 years to maturity, deliverable from a basket at the conversion factors, expiring in March, June, September and December) is the reference contract of the euro rates market, with the Bobl (4.5 to 5.5 years), the Schatz (1.75 to 2.25 years) and the Buxl (24 to 35 years) completing the curve; the cheapest to deliver and the basis trade between the future and the cash Bund are the market’s mechanics.
The Euribor to €STR transition: the three-month Euribor future was the euro money market’s hedge for thirty years; after the euro short-term rate replaced EONIA in 2019 and the regulators pushed the risk-free rates, Eurex launched the three-month €STR futures in 2023 and relaunched the Euribor contracts in 2024 beside them, in competition with ICE Futures Europe’s euro contracts in London; EMIR 3’s active account requirement covers the €STR futures.
Prisma: Eurex Clearing’s portfolio-based margin model (2013) replaces the older risk-based margining with a filtered historical simulation across the correlated contracts in a liquidation group, with the stress scenarios, the liquidity and concentration add-ons and the cross-margining between the listed and the OTC positions; the counterpart of CME’s SPAN 2 and OCC’s STANS.
GC Pooling: the euro area’s main cleared general collateral repo market, where the banks lend and borrow cash against standardized baskets of ECB-eligible collateral (the ECB basket, the extended basket, the equity basket) through Eurex Repo, cleared at Eurex Clearing and settled in triparty at Clearstream, with the received collateral reusable for the Bundesbank’s operations; the GC Pooling rates are the secured euro money market’s reference beside the ECB’s deposit rate.
Eurex Clearing: Trade Capture, Prisma Margin, the OTC Swap Service Under EMIR 3, the Daily Cycle Through T2 and Clearstream, the Default Fund
Deutsche Börse’s CCP: the trades captured from Eurex, the swap venues, Eurex Repo and Xetra, the initial margin on Prisma with the cross-margining of the swaps against the Bund and €STR futures, the OTC swap service with the partnership program and EMIR 3’s active account requirement pulling the euro swaps from London, the daily cycle of settlement prices, variation margin and premiums paid through T2 by 08:00 CET, the deliveries and the collateral through Clearstream with the cash at the Bundesbank, the default fund with the waterfall, the default management and the auction, and BaFin, the Bundesbank, the EMIR college and ESMA.
Worked example, illustrative:owner Deutsche Börse AG; Eurex Clearing AG, a credit institution and an EMIR CCP in Frankfurt; the OTC swap service since 2012, the partnership program since 2018handles every Eurex contract, the euro interest rate swaps, the GC Pooling and Repo Market trades, the Xetra cash market under clearing choice; 8,000,000 contracts a day, EUR 30,000,000,000,000 of swaps outstanding, EUR 150,000,000,000 of repo, illustrativemembers the general and direct clearing members (banks, brokers) carrying the trading members and the clients; the ISA Direct members with their clearing agentslinks T2 and the Bundesbank for the cash and the margin; Clearstream Banking Frankfurt on T2S for the deliveries and the collateral; Eurex, Xetra, Eurex Repo and the swap venues as trade sourcesoverseen by BaFin and the Bundesbank under EMIR; the college and ESMA’s CCP Supervisory Committee; the CFTC as a DCO; recognized in the UK and Switzerlandthe cycle capture through the day; margin by 08:00 CET and intraday; settlement prices at 17:30; the cash cycle through T2 the next morning; the deliveries on the expiry and settlement dates

One clearing house for the Bund futures, the euro repo and the swaps the EU wants cleared at home: Prisma margins them together, T2 and the Bundesbank carry the cash, Clearstream the deliveries, and EMIR 3’s active account is the regulation pushing the swaps here while the basis against London pulls the other way.
EMIR 3 and the active account: the December 2024 revision of EMIR requires the EU firms subject to the clearing obligation and above the thresholds to hold an active account at an EU CCP for the euro and Polish zloty interest rate swaps and the €STR futures, applicable from June 2025, with the representativeness obligation (a number of trades per class cleared there) and the reporting; the aim is to reduce the reliance on LCH Ltd, which the Commission recognized as a tier 2 CCP until June 2028; the industry opposed a quantitative target and the requirement stayed qualitative.
The partnership program: in 2018 Eurex Clearing offered the dealers and the buy side a share of the economics and the governance of its OTC swap service in exchange for moving volume, after the Brexit vote raised the question of euro clearing in London; the program took the euro swap share from near zero to a fifth or more (illustrative), with the CME-LCH-style basis between Eurex and LCH as the cost of the split liquidity.
ISA Direct: Eurex Clearing’s model (2016) under which a buy-side firm becomes a direct clearing member with a clearing agent (a bank) that provides the default fund contribution and the default management obligations, so that the client’s positions and collateral are its own at the CCP rather than held through a member; the EU counterpart of FICC’s sponsored service.
The central bank of issue: an EU CCP holds its cash at the central bank where it can (Eurex Clearing at the Bundesbank, LCH SA at the Banque de France) under the EMIR requirement to minimize the commercial bank exposure, and the Eurosystem sits in the college as the central bank of issue of the euro with the ECB’s oversight standards for the CCPs; the Fed gives the same to the US SIFMUs under Title VIII.
Clearstream: the ICSD in Luxembourg and the German CSD on T2S, the Bridge, the Collateral Management and the Fund Services
The Deutsche Börse group’s depositories: the Eurobonds, the international positions and the German securities held in two depositories, the Eurobond settlement on Clearstream Banking Luxembourg’s own books in commercial bank money with the bridge to Euroclear Bank, the German settlement at Clearstream Banking Frankfurt on T2S in central bank money at the Bundesbank, the collateral management through Xemac, the triparty and the Global Liquidity Hub, the fund order routing and custody through Vestima, the asset services for the coupons, the corporate actions, the issuers and the Bund auctions, and the CSSF, BaFin, the Bundesbank and CSDR.

Two depositories in one group: the Eurobonds settle on Clearstream’s own books in Luxembourg, in commercial bank money, with a bridge to Euroclear; the German shares and Bunds settle at Frankfurt on T2S, in central bank money. The collateral management between them is what the euro repo market and the Bundesbank’s operations run on.
The two ICSDs: Euroclear Bank (1968, Brussels) and Cedel (1970, Luxembourg, now Clearstream Banking Luxembourg) were built by the Eurobond market’s banks to settle the bonds issued outside any national system; each holds the bonds through a common depositary or safekeeper and settles on its own books in commercial bank money, and the bridge between them (1980, electronic since 1993) makes the two one market; a Eurobond is held in one or the other, never in a national CSD.
Commercial versus central bank money: an ICSD settles the cash leg on its own books (it is a bank, and the participants hold cash accounts with it, with the ICSD holding the currencies at its correspondent banks), so the settlement carries the ICSD’s credit; a CSD on T2S settles the cash on the central bank’s accounts, with no credit risk but the central bank’s hours and currencies; CSDR regulates both, the ICSDs as banking-type CSDs with the extra capital.
The collateral chain: the German banks pledge their collateral to the Bundesbank through CBF’s Xemac (the system that marks and substitutes the pledged securities), the Eurosystem’s ECMS since June 2025 reads the pool, the GC Pooling repos reuse the same baskets in triparty, and the Global Liquidity Hub lets a bank move a position from CBL to CBF or to a CCP’s margin account without a settlement; the collateral efficiency of the group is its argument against Euroclear’s Collateral Highway.
Vestima: Clearstream’s fund processing platform (2000) routes the subscription and redemption orders of the banks and the distributors to the funds’ transfer agents, settles the cash and holds the units in custody at the ICSD, so that a bank distributing 50,000 funds has one connection and one custody account; the Fund Centre (2020, the former UBS Fondcenter) adds the distribution agreements and the retrocessions; the Luxembourg and Irish fund industries’ plumbing.
EEX and ECC: the Power, Gas and Carbon Markets From the Order to the Delivery Through the Grid, the Hubs and the Union Registry
The European Energy Exchange and its clearing house: an order in a German power future, a TTF gas contract or an EU allowance through the trading participants, the match on the exchange and the EU allowance auctions with the spot power on EPEX SPOT, the novation at European Commodity Clearing with the margin on the energy curves called through T2 and the settlement banks, the daily settlement prices and the variation margin the 2022 crisis multiplied, the delivery of the power through the transmission system operators, the gas at the virtual trading points and the allowances in the Union Registry, and the Saxon exchange supervisor, BaFin, ACER under REMIT and the Commission.
Worked example, illustrative:owner Deutsche Börse AG as the majority shareholder of EEX Group (Leipzig, 2002 from the merger of the Frankfurt and Leipzig power exchanges); EPEX SPOT (Paris) and ECC inside the grouphandles power, gas, emissions, freight and agricultural derivatives, the EU allowance auctions, the spot power and gas through EPEX SPOT and the gas markets; 500,000 megawatt-hours and 10,000,000 allowances a day, illustrativemembers the trading participants (utilities, traders, industrials, banks, funds); the clearing members of ECC (banks and licensed energy companies) carrying themlinks the transmission system operators and the balancing groups for the power delivery; the virtual trading points for the gas; the Union Registry for the allowances; T2 and the settlement banks for the cashoverseen by the exchange supervisory authority of Saxony; BaFin and the Bundesbank for ECC under EMIR; ACER under REMIT; the Commission for the allowance auctionsthe day the derivatives 08:00 to 18:00 CET; the day-ahead auction at 12:00; the intraday market continuous; settlement prices at the close; margin the next morning; the physical delivery per schedule

The power and gas curves trade in Leipzig, the EU auctions its carbon there, and one clearing house novates every trade and delivers the electricity through the grid operators, the gas at the hubs and the allowances in the Union Registry. The 2022 energy crisis showed what the margin on an energy curve can do to a utility.
The power futures: a European power future is a financial contract on the average spot price of a delivery period (a base or peak load profile for a day, week, month, quarter or year in a bidding zone), settled in cash against the day-ahead auction prices of EPEX SPOT or the other spot exchanges; the physical delivery happens in the spot market, through the balancing groups the transmission system operators keep; the Phelix (German-Luxembourg baseload) is the continental benchmark, with the French, Italian, Spanish and Nordic contracts beside.
The EU ETS auctions: the EU emission allowances enter the market through the auctions EEX runs as the common auction platform on behalf of the Commission and 25 member states (Germany and Poland had their own platforms at times) under the Auctioning Regulation, several times a week, with the proceeds to the member states and the Innovation and Modernisation Funds; the secondary market trades the allowances as spot and futures on EEX and ICE Endex, and the allowances are financial instruments under MiFID II and MAR.
The 2022 crisis: the gas and power prices of 2022 multiplied the margin requirements on the utilities’ hedges (a generator short the forward power at EUR 100 facing a market at EUR 1,000 owes the variation margin on the difference), the margin calls reached tens of billions across Europe, the governments guaranteed the utilities’ margin facilities and the EU’s EMIR 3 widened the collateral the non-financial counterparties may post (the bank guarantees, the public guarantees); ECC and the exchange raised the margins and the prices came down in 2023.
REMIT: the EU regulation on wholesale energy market integrity and transparency (2011, revised in 2024) is the market abuse and reporting regime of the physical and financial energy markets, with ACER (the EU agency in Ljubljana) collecting the trade and order reports from the exchanges, the brokers and the participants and the national energy regulators enforcing; it sits beside MAR and MiFID II for the derivatives, and ACER’s surveillance is the energy market’s counterpart of the NCAs’.
CDSClear: the iTraxx and the Single Names From Submission to the Jump-to-Default Margin, the Daily Cycle and the Credit Event Auction
LCH SA’s credit default swap clearing: a CDS submitted from the venues and the affirmation platforms and novated within seconds, the margin on the spread risk, the jump to default and the wrong-way add-on called through T2 and the Banque de France, the client clearing under EMIR’s segregation with the porting and the clearing obligation on the iTraxx indexes, the daily cycle of end-of-day prices, coupons and compression, a credit event ruled by the ISDA determinations committee and settled in cash at the auction price, and the ACPR, the AMF, the Banque de France, the college and the CFTC.

The credit market’s clearing house in Paris: the iTraxx and the single names novate within seconds, the margin prices the jump to default the rates CCPs never see, and a credit event becomes cash at the ISDA auction’s recovery price. Since ICE left the European CDS in 2023, it is the EU’s only one.
LCH SA: the Paris clearing house (the Banque Centrale de Compensation of 1969, Clearnet from 1999 as the CCP of the Paris Bourse and then of Euronext) merged with the London Clearing House in 2003 into LCH.Clearnet, now LCH Group under LSEG; it clears the European CDS (CDSClear), the euro government bond cash and repo (RepoClear SA) and a few remaining cash markets, while LCH Ltd in London clears the swaps, the gilts, the FX and the UK equities; Euronext’s markets left for Euronext Clearing in 2023 and 2024.
Jump-to-default risk: a CDS clearing house margins not only the spread moves but the loss if a reference entity defaults overnight, which the recovery rate and the position’s direction determine; the JTD component is why a seller of protection on a distressed name posts far more than the spread value-at-risk would require, and why a member cannot clear protection sold on itself or its own sector without the wrong-way add-on.
The credit event process: under the ISDA 2014 definitions, a market participant asks the regional determinations committee (five dealers and five buy-side firms voting) whether a credit event has occurred; if so, the auction (run by Creditex and Markit) sets the final price from the dealers’ two-way markets and the net open interest, and the cleared and the bilateral contracts settle to it; the CCP settles its contracts in cash on the auction price without the physical delivery.
The EU clearing obligation for credit: EMIR’s clearing obligation covers the iTraxx Europe Main and Crossover indexes (the five-year series) for the financial counterparties and the large non-financial ones, from 2017; the single names and the options are cleared voluntarily; the US clearing mandate covers the CDX and the iTraxx indexes at ICE Clear Credit and CDSClear, and the two CCPs compete for the dealers’ index books with the margin offsets.
RepoClear SA: the Euro Government Bond Cash and Repo CCP From Trade Capture to the VaR Margin, Netting, Settlement on T2S and €GCPlus
LCH SA’s government bond clearing: the cash and repo trades in the French, Italian, Spanish, German and the other euro debt captured from MTS, BrokerTec, Tradeweb and the voice brokers, the margin from the VaR model with the sovereign and concentration add-ons called through T2 and the Banque de France, the overnight netting into one position per ISIN per settlement date that is the dealers’ balance sheet relief, the delivery-versus-payment settlement through the national CSDs on T2S with the €GCPlus general collateral in Euroclear’s triparty, the sponsored clearing that brings the funds and the treasuries in, and the ACPR, the AMF, the Banque de France, the college and ESMA.

The euro repo market clears in Paris: every government bond trade and repo from the platforms nets into one position per bond per day, the margin prices the sovereign spread, and the net settles through the national depositories on T2S. The netting is the balance sheet the dealers clear for, and the funds come in behind a sponsor.
The euro repo market: the banks and dealers fund their government bond inventories and lend cash against them in repo, overnight to a year, with the special repo on a named bond (the bonds in demand trade below the general collateral rate) and the general collateral against baskets; most of the interdealer market clears at RepoClear SA, Eurex Clearing (GC Pooling and the Repo Market) and Euronext Clearing (the Italian market), and the cleared repo nets on the dealers’ balance sheets, which the uncleared repo with the clients does not.
€GCPlus: the triparty general collateral repo product LCH SA launched in 2014 with the Banque de France and Euroclear France: standardized baskets of ECB-eligible collateral (the high-quality and the extended baskets), the trades cleared at RepoClear SA, the collateral allocated in Euroclear’s triparty and reusable for the Banque de France’s refinancing operations; the French counterpart of Eurex’s GC Pooling.
The sovereign margin: a CCP clearing the euro government bonds margins the sovereign risk of each issuer (the Italian and the Spanish spreads against the Bunds) and the concentration of a member’s book in one issuer; in November 2011 LCH SA and CC&G raised the margins on the Italian bonds as the spread passed 450 basis points, which the market read as a signal, and the procyclicality of the CCP margins has been the regulators’ subject since (the EMIR anti-procyclicality measures of 2013 and 2024).
The balance sheet relief: under the accounting and the leverage ratio rules a dealer may net a repo and a reverse repo with the same counterparty on the same settlement date, which a CCP makes possible across the whole market; the netting is why the dealers clear their repo, why the sponsored models bring the clients in, and the rationale the SEC used for the US Treasury clearing mandate of 2026 and 2027.
Euroclear Bank: the ICSD’s Own Books, the Bridge and the Links, the Collateral Highway, the Eurobond Closings and the Immobilized Russian Assets
The international CSD in Brussels: the Eurobonds and the cross-border positions of 50 markets held for 2,000 participants, the settlement on the ICSD’s own books in commercial bank money in the overnight batch and the real-time day, the bridge with Clearstream and the links to the national CSDs on T2S and beyond, the Collateral Highway with the triparty repo, the CCPs’ margin and the central banks’ collateral, the Eurobond closings, the coupons and the corporate actions, the immobilized Russian assets and the windfall contribution, and the NBB, the FSMA, CSDR and the Eurosystem.

The Eurobond market has no national depository: it lives on the books of two banks in Brussels and Luxembourg, and Euroclear Bank is the larger. The trades settle in commercial bank money, the collateral of the euro market moves on the same accounts, and since 2022 the frozen Russian reserves sit on its balance sheet.
The ICSD model: Euroclear Bank is a bank, so its participants hold cash accounts with it and the settlement of a Eurobond trade is a book entry on both the securities and the cash side inside the bank, final under the Belgian settlement finality law; the bank extends intraday credit to let the participants settle before their cash arrives and holds the currencies at its correspondent banks; CSDR regulates this as a banking-type CSD with the extra capital and the liquidity requirements the central-bank-money CSDs do not need.
The bridge: the electronic link between Euroclear Bank and Clearstream Banking Luxembourg (1980, automated in 1993, with the daytime cycles since 2004 and the hourly settlement since) through which a Eurobond held in one ICSD is delivered against payment to a participant of the other; the two ICSDs keep accounts with each other and settle the bridge transactions in their own books, which makes the Eurobond market one market in two systems.
The Collateral Highway: Euroclear’s 2012 name for the collateral services across its group (Euroclear Bank, the ESES CSDs, Euroclear UK and International, the partner CSDs): the triparty agent role for the repo and the securities lending, the segregated margin accounts for the CCPs and the uncleared margin, the central banks’ collateral, and the mobilization of a participant’s securities from the CSD where they are held to the account where they are needed; the counterpart of Clearstream’s Global Liquidity Hub and of BNY’s tri-party in the US.
The immobilized Russian assets: the EU sanctions of February 2022 froze the Central Bank of Russia’s reserves held in the EU, most of them securities and cash at Euroclear Bank (EUR 190,000,000,000, illustrative), which cannot be moved and whose coupons and redemptions pile up as cash; the EU’s 2024 regulation channels the net profits on that cash to Ukraine and the G7’s 2024 loan is repaid from them, while the confiscation of the principal is debated against the legal and the Euroclear-stability objections; Euroclear’s Russian assets are frozen in return.
Euroclear ESES: the French, Belgian and Dutch CSDs, Instructions and Settlement on T2S in Central Bank Money, the Links and the Asset Services
The three national CSDs of the Euroclear group: the French, Belgian and Dutch securities held in book entry on one platform, the instructions for T+2 from the CCPs’ net positions, the custodians’ DVP, the free deliveries and the OAT auctions, the settlement on T2S in the night-time cycles and the real-time day with the cash on the dedicated cash accounts at the Banque de France, the NBB and DNB, the cross-border settlement across the T2S links and through Euroclear Bank, the asset services for the dividends, the coupons, the corporate actions and the registers, and the CSDR authorities with their central banks and the Eurosystem behind T2S.
Worked example, illustrative:owner Euroclear Holding; the Sicovam (1949), the CIK (1967) and the Necigef (1977) joined Euroclear in 2001 and 2002 and merged their platforms into ESES in 2007 to 2009handles book-entry custody and settlement of the French, Belgian and Dutch equities, government and corporate bonds, funds and money market instruments; EUR 10,000,000,000,000 under custody, 400,000 settlements a day, illustrativemembers the participant banks, brokers and custodians; the CCPs; the issuers and the holders behind them; Euroclear Bank as the group’s own participantlinks T2S and the dedicated cash accounts at the Banque de France, the NBB and DNB; the T2S links to the other CSDs; Euroclear Bank for the foreign holders; Euronext Clearing, Cboe Clear Europe and LCH SA as the CCPsoverseen by the AMF and the Banque de France, the NBB and the FSMA, the AFM and DNB under CSDR; the Eurosystem for T2Sthe day instructions matched through the day; night-time settlement from 20:00 CET; real time 05:00 to 16:00 DVP cutoff; settlement T+2; the asset services daily

The CAC 40 shares and the OATs live at Euroclear France, the Belgian and Dutch securities next door on the same platform, and all three settle on T2S in central bank money at their central banks. The foreign holders of the French debt come in through Euroclear Bank, the group’s own participant.
ESES: Euroclear Settlement of Euronext-zone Securities, the single platform Euroclear built in 2007 to 2009 for its French, Belgian and Dutch CSDs after Euronext merged the three markets, with one account structure, one matching and one set of procedures, settled in central bank money through the three central banks; in 2016 the three CSDs moved their settlement to T2S and kept the platform for the custody and the asset services.
T2S and the night-time settlement: T2S settles in two night-time cycles from 20:00 CET (the first for the bulk of the next day’s instructions, the second for the rest) and in real time from 05:00 until the 16:00 cutoff for the DVP and 18:00 for the free deliveries, with the partial settlement and the recycling of the failed instructions; the night-time cycles settle most of the volume before the European morning, which is how the T+2 market absorbs the day.
Auto-collateralization: on T2S a participant whose dedicated cash account is short can settle a purchase against the securities it is receiving (the collateral on flow) or holds (on stock), with the central bank granting the intraday credit automatically and reversing it when the cash arrives; the payment banks can grant the same to their clients; the feature is why T2S settles the volume it does without the gross liquidity each delivery would otherwise need.
The French financial transaction tax: since 2012 a 0.3% tax on the purchases of the shares of the French companies above EUR 1,000,000,000 of market capitalization, collected by the custody chain and paid to the French Treasury through Euroclear France as the central collection agent, which makes the CSD a tax infrastructure too; the Italian and the Spanish taxes work through their CSDs the same way.
T2: the Euro RTGS From 02:30 to 18:00 CET, the Main Cash Accounts, the Intraday Credit and the Ancillary Systems Settling Through It
The Eurosystem’s real-time gross settlement system: a corporate payment ordered through the bank, formatted in ISO 20022 and sent through ESMIG, settled on the RTGS dedicated cash accounts at once or queued against the liquidity management and the intraday credit line from the main cash account, credited to the receiving bank final and irrevocable, the ancillary systems (EURO1, STEP2, the CCPs, the CSDs, CLS) and the Eurosystem’s own T2S and TIPS settling through it, the end of the day with the cutoffs, the standing facilities and the reserves, and the Eurosystem as operator with the ECB’s oversight apart.
Worked example, illustrative:owner the Eurosystem (the ECB and the national central banks); operated by the Banque de France, the Bundesbank, the Banca d’Italia and the Banco de España; T2 since March 2023, TARGET2 since 2007, TARGET since 1999handles euro payments in central bank money, final on processing; 400,000 a day worth EUR 2,500,000,000,000, illustrative; the cash legs of the euro area’s infrastructuresmembers the banks with main cash accounts and RTGS accounts at their national central banks (1,000 direct participants, 40,000 addressable BICs, illustrative); the ancillary systems; the Eurosystem itselflinks EURO1, STEP2, RT1 through TIPS, the CCPs through their central banks, the CSDs; T2S and TIPS through the central liquidity management; CLS through its account at the ECB; ECMS for the collateraloverseen by the ECB’s oversight function under the SIPS Regulation, apart from the operator; the Governing Council through the Market Infrastructure Boardthe day night-time window from 19:30 CET; the day from 02:30; customer cutoff 17:00; interbank cutoff 18:00; the standing facilities at the close; ISO 20022 since March 2023

Every euro that matters ends its day on an account at a national central bank, moved by T2 and final the moment it moves. The main cash account is where a bank keeps its reserves and its credit line, and the RTGS, the securities platform and the instant service all draw on it.
The T2-T2S consolidation: in March 2023 the Eurosystem replaced TARGET2 with T2, built on the T2S technical platform, with the central liquidity management module (one main cash account per bank holding the reserves and the credit line, from which the liquidity is moved to the RTGS, T2S and TIPS dedicated cash accounts), the ISO 20022 messages, the single gateway (ESMIG) and the common reference data; the migration was delayed from November 2022 by four months and went live in one weekend.
The intraday credit: a bank in T2 may draw intraday credit on its main cash account free of charge and without limit within the collateral it has pledged to its national central bank (now through ECMS), so that the RTGS never stops a creditworthy bank for the timing of its inflows; the credit must be repaid by the close, or it becomes an overnight marginal lending at the penalty rate; the US Fedwire’s daylight overdraft is the uncollateralized counterpart.
The ancillary system procedures: T2 settles the other infrastructures through standard procedures (the real-time settlement of a single debit and credit, the bilateral and multilateral net settlements, the settlement on dedicated sub-accounts for the CSDs outside T2S) under which each system sends its settlement instructions and T2 moves the balances between the participants’ accounts and the system’s technical account at the time the system chooses.
The SIPS Regulation: the ECB’s regulation of 2014 (revised in 2017 and 2021) applies the CPMI-IOSCO principles for financial market infrastructures to the systemically important euro payment systems it identifies (T2, EURO1, STEP2, CORE(FR) and the Spanish and Italian retail systems at times), with the requirements on governance, credit and liquidity risk, settlement finality, operational risk and the participants’ access, enforced by the Eurosystem’s oversight function, which oversees T2 at arm’s length from the operator.
T2S: the CSDs on the Platform, Instructions and Matching, the Night-Time Cycles, the Real-Time Day, the Cash and the Auto-Collateralization
The Eurosystem’s securities settlement platform: the 24 CSDs that outsource their settlement to it, the instructions from their participants and the directly connected parties matched on the platform including the cross-CSD trades, the two night-time cycles from 20:00 CET that settle most of the volume, the real-time window to the 16:00 DVP cutoff with the partial settlement and the CSDR penalties, the cash on the dedicated cash accounts funded from T2 with the central bank and client auto-collateralization and the end-of-day sweep, and the Eurosystem’s oversight, the CSDs’ authorities and the T+1 move of October 2027.

One settlement engine for 24 depositories: the securities and the cash settle together in central bank money, mostly at night, with the central banks lending the liquidity against the securities themselves. The CSDs keep their names and their clients; the Eurosystem runs the plumbing, and T+1 will run on it in 2027.
The T2S project: proposed by the ECB in 2006 to end the fragmentation of the European securities settlement (the Giovannini barriers of 2001 and 2003), built by the four central banks and launched in June 2015 with Monte Titoli, the Greek, Maltese, Romanian and Swiss-owned CSDs in the first wave, then the Portuguese, Belgian and NBB systems, the ESES CSDs and the Danish VP in 2016, Clearstream Banking Frankfurt and the Austrian, Hungarian, Slovenian and Slovak CSDs in 2017, the Baltic CSDs in 2017, and Euroclear Bank, Euroclear Finland and the Bulgarian and Croatian CSDs in 2023; Iberclear joined in 2017.
The CSDs’ role on T2S: a CSD on the platform remains the legal depository of its securities and the point of access for its participants, keeps the issuer services, the corporate actions and the registers, and opens the securities accounts on T2S in its own books’ image; the settlement, the matching and the cash are the platform’s; the participants may connect directly (the large custodians and CCPs) or through their CSD.
The Danish krone and the other currencies: T2S settles in euro and, since October 2018, in Danish krone for the Danish CSD’s participants through Danmarks Nationalbank’s dedicated cash accounts; the Swedish and Norwegian CSDs stayed outside; the platform was built multi-currency and the digital euro and the wholesale central bank money experiments of 2024 and 2025 (the settlement of tokenized securities against T2 and T2S cash) are the next uses discussed.
T+1 in the EU: the Regulation of 2025 amending CSDR moves the standard settlement cycle from T+2 to T+1 on October 11, 2027, aligned with the UK and Switzerland, after the US move of May 2024; ESMA’s T+1 governance, the industry’s roadmap and the T2S changes (the matching deadlines, the night-time cycle, the partial settlement) are the preparation; the settlement efficiency and the penalties are the metrics the regulators watch for the transition.
The Eurosystem’s Platforms›TIPS
TIPS: the Instant Payment Settled in Central Bank Money Within Seconds, Around the Clock, Under the Instant Payments Regulation
The Eurosystem’s instant payment settlement service: an instant credit transfer ordered on a phone on a Sunday night under the SCT Inst scheme with the verification of payee, settled on the TIPS dedicated cash accounts in central bank money within seconds, the other instant systems (RT1, the national ACHs) settling in TIPS through their technical accounts since the reachability measures, the Instant Payments Regulation’s reachability, sending, fee and verification obligations since 2025, and the Eurosystem as operator, the ECB as overseer and the EPC’s scheme.

A euro paid from a phone at ten on a Sunday night settles in central bank money in under five seconds: the two banks’ prefunded accounts at the Eurosystem move, final, and the ACHs that used to net the retail payments now settle through the same accounts. The 2024 regulation made it the default of the euro retail payment.
The SCT Inst scheme: the European Payments Council’s scheme of November 2017 for the instant SEPA credit transfer (ten seconds end to end, EUR 100,000 maximum since July 2020, available every moment of the year, in ISO 20022), optional for the PSPs until the Instant Payments Regulation made it mandatory; the scheme defines the messages and the timeouts, the settlement layer (TIPS, RT1, the national ACHs) is the PSP’s choice.
The reachability measures: in July 2020 the ECB decided that every PSP adhering to SCT Inst and reachable in TARGET2 must be reachable in TIPS, as a participant or a reachable party, and that every ACH offering instant payments must move its technical account to TIPS (done by February 2022), so that an instant payment can reach any euro-area account through one settlement layer; the measures ended the fragmentation of the instant payment systems by country.
The Instant Payments Regulation: Regulation (EU) 2024/886 of March 2024 amended the SEPA Regulation to require the euro-area PSPs to receive instant payments by January 9, 2025 and to send them by October 9, 2025, at a price no higher than the regular credit transfers, with the verification of payee service and the daily sanctions screening of the customers; the non-euro member states follow in 2027; the payment institutions and e-money institutions gained direct access to the designated payment systems under the Settlement Finality Directive amendment.
The cross-currency service: TIPS settles the Swedish krona since February 2024 (the Riksbank moved its RIX-INST service to the platform) and the Danish krone since April 2025 (with Denmark’s migration to T2 and TIPS), and the Eurosystem and the Riksbank tested the cross-currency instant payments between the euro and the krona; Norges Bank plans to join; the platform is the Eurosystem’s multi-currency instant layer the way T2S is for securities.
ECMS: the Eurosystem Collateral Management System From the Mobilization on T2S and in Triparty to the Valuation, the Credit Line in T2 and the Lifecycle
The fourth TARGET service since June 2025: the counterparties’ collateral pools at their national central banks held in one system, the mobilization of the marketable securities on T2S, the credit claims and the triparty baskets, the daily valuation with the haircuts and the eligibility of the collateral framework, the intraday credit line in T2 and the monetary policy operations secured on the pool, the lifecycle of the coupons, the maturities, the corporate actions and the substitutions, and the Governing Council’s framework with the Eurosystem’s oversight.
Worked example, illustrative:owner the Eurosystem; built and operated by the Banque de France and the Banco de España; live since June 16, 2025, replacing the 20 national collateral management systemshandles the collateral the counterparties pledge for the Eurosystem’s monetary policy credit and the intraday credit in T2: marketable securities, credit claims, triparty baskets; EUR 1,500,000,000,000 mobilized, illustrativemembers the monetary policy counterparties (the banks) with a pool at their national central bank; the national central banks as the lenders; the CSDs and the triparty agents as the mobilization channelslinks T2S and the CSDs for the securities; T2 for the credit line and the operations’ cash; Euroclear Bank, Clearstream and the national triparty agents; the common pricing hub for the valuationsoverseen by the Governing Council’s collateral framework; the Market Infrastructure Board; the Eurosystem’s oversight functionthe day mobilizations during T2S’s hours; valuation daily; the credit line updated in real time in T2; the operations settled on their dates; the margin calls when the pool falls short

Every bank that borrows from the Eurosystem pledges a pool of securities and loans to its central bank, and since June 2025 one system holds, values and haircuts every pool and sets the credit line in T2 from it. Twenty national systems became one, and the ECB’s refinancing runs on it.
The collateral framework: the Eurosystem lends only against adequate collateral (the Statute’s Article 18), and the Governing Council’s General Documentation sets the eligible assets (the marketable securities meeting the credit quality, the credit claims, the non-marketable retail debt instruments at times), the haircuts and the limits; the framework widened in the crises (the ABS, the lower-rated government bonds, the additional credit claims of 2011 and 2020) and is being unwound and unified since 2024.
The pooling system: the Eurosystem’s claim on a counterparty is secured on the whole pool of collateral it has mobilized rather than on specific assets earmarked to each operation (the earmarking system some central banks used), so that a bank manages one pool for its refinancing operations, its marginal lending and its intraday credit line, substitutes freely and is margin-called on the pool’s total; ECMS made the pooling the single model for the euro area.
The credit claims: the loans the banks have made to companies and public entities, pledged to the central bank under the national laws (the assignment or the pledge of the receivable), are a third or more of the mobilized collateral since 2012, valued by the central banks from the banks’ internal ratings (the internal ratings-based systems the Eurosystem accepts) or the external assessments; ECMS harmonized the registration and the updates that the national systems handled each in their own way.
The triparty mobilization: a bank can mobilize collateral through a triparty agent (Euroclear Bank, Clearstream Banking Luxembourg and Frankfurt, the Spanish and Italian CSDs’ services) that allocates a basket to the central bank’s account, values and substitutes it and reports to ECMS, so that the bank’s collateral management for the central bank uses the same agent as its repo and margin collateral; the agents’ models were harmonized for the single system.
EBA Clearing›EURO1
EURO1: the Single Obligation Structure, the Limits and the Debit Cap, Finality on Processing and the End-of-Day Settlement in T2
EBA Clearing’s large-value net system: a commercial payment routed to EURO1 rather than T2 for the liquidity it saves, the processing against the bilateral limits and the multilateral debit cap under the single obligation structure that makes each payment final as it is processed, the receiving participant’s position adjusted at once with the liquidity pool at the ECB behind, the end-of-day settlement of the net positions in T2 as an ancillary system, and the ECB’s oversight under the SIPS Regulation with the system’s place beside T2 and the instant payments.
Worked example, illustrative:owner EBA Clearing, owned by its user banks; founded in 1998 by the Euro Banking Association’s banks for the euro’s start; the single obligation structure under German lawhandles large-value and commercial euro payments netted continuously; 190,000 a day worth EUR 200,000,000,000, illustrative; STEP1 for the smaller banksmembers about 40 participant banks, the large euro area and international banks; the STEP1 banks through them; the liquidity pool deposits at the ECBlinks T2 for the end-of-day settlement as an ancillary system; the ECB for the liquidity pool and the settlement account; SWIFT for the messagesoverseen by the ECB as lead overseer under the SIPS Regulation; designated under the Settlement Finality Directivethe day processing from the early morning to the cutoff; the limits adjustable until 02:00 CET for the same day; the net settlement in T2 at 16:00 CET; the positions back to zero

The banks’ own large-value system nets the commercial euro payments through the day into one position per participant, final as each payment is processed under a legal structure built for it, and settles the net once in T2 at four o’clock. A tenth of T2’s value, declining, and still the euro’s CHIPS.
The single obligation structure: EURO1’s legal design under German law in which each participant, at every moment of the day, has one single claim on or obligation to the system as a whole rather than bilateral claims on the other participants; each processed payment adjusts the sender’s and the receiver’s single positions, so there are no pending bilateral claims to unwind and the payment is final when processed; the structure was validated by legal opinions in every participant’s jurisdiction and is the model for a net system with finality.
The limits and the liquidity pool: each participant sets a bilateral limit on every other participant (the credit it extends in the netting) and the system derives the multilateral credit and debit caps; the liquidity pool is the participants’ equal cash deposits at the ECB, sized to cover the largest debit cap, so that the end-of-day settlement completes if one participant fails to pay, with the loss shared among the survivors; the design is the CPMI’s Lamfalussy standards of 1990 for a net system.
EURO1 beside T2: at the euro’s start the banks ran EURO1 as the liquidity-saving alternative to TARGET’s gross settlement; as T2 added the liquidity-saving offsetting and the instant and batch systems took the retail flow, EURO1’s share fell, and EBA Clearing’s study of its future positioning (2017) led to the ISO 20022 migration and the longer hours rather than a closure; the system continues as the private large-value alternative, with the CPMI’s question of whether a net system is still needed beside an efficient RTGS.
EBA Clearing: the company owned by its user banks that runs EURO1 and STEP1 (large value), STEP2 (the SEPA batch) and RT1 (the instant payments), founded in 1998 by the Euro Banking Association (the association of the banks that ran the ECU clearing of the 1980s); its systems are overseen by the ECB as the systemically important and the prominent payment systems of the euro, and its shareholders are the banks that use it.
EBA Clearing›STEP2
STEP2: the SEPA Credit Transfers and Direct Debits in Batch, the Cycles, the Net Settlement in T2 and the Files to the Receiving Banks
EBA Clearing’s pan-European ACH: an employer’s payroll file of SEPA credit transfers and a utility’s direct debit collections sent through their banks in ISO 20022, the processing by cycle with the validation against the scheme rules, the sorting by receiving bank and the net positions, the settlement of the net debits and credits in T2 as an ancillary system, the receiving banks’ credits to the employees and the direct debit collections with the refund rights and the national ACHs’ interoperability, and the ECB’s oversight, the EPC’s schemes and the SEPA Regulation.
Worked example, illustrative:owner EBA Clearing, owned by its user banks; STEP2 since 2003, the SEPA credit transfer service since January 2008, the direct debit since November 2009handles SEPA credit transfers and SEPA Core and B2B direct debits in batch; 50,000,000 transactions a day, illustrative; the payroll, the pensions, the bills, the supplier paymentsmembers the direct participants (the large banks, the national ACHs); 4,000 PSPs reachable through them across the 36 SEPA countrieslinks T2 for the net settlement by cycle; the national ACHs under the interoperability framework; the EPC’s schemes; SWIFT and the networks for the filesoverseen by the ECB as lead overseer under the SIPS Regulation; designated under the Settlement Finality Directive; the EPC for the schemes; the PSD and the SEPA Regulation for the rulesthe day the files through the day to the cycle cutoffs; several settlement cycles in T2 from the night to the afternoon; next-day execution at most; the direct debits on their collection dates

The payroll, the pensions and the bills of the euro area travel as files: the banks send their SEPA transfers and direct debits in batches, STEP2 sorts and nets them by cycle, the net settles in T2 and the files go on to the receiving banks. The system that made SEPA real, and the one the instant payments are emptying.
SEPA: the Single Euro Payments Area (2008 for the credit transfers, 2009 for the direct debits, the migration completed in 2014 under the SEPA Regulation) made the euro credit transfer and direct debit the same instrument in 36 countries, on the IBAN and the ISO 20022 formats, with the EPC’s rulebooks as the schemes; STEP2 was the first pan-European ACH for them and the national ACHs adapted or linked to it.
The SEPA direct debit: the Core scheme for the consumers (the mandate held by the creditor, the pre-notification, the refund right of eight weeks for an authorized debit and thirteen months for an unauthorized one) and the B2B scheme for the businesses (no refund right, the mandate checked by the debtor bank); the direct debit is how the European households pay their utilities, rent and subscriptions, and the R-transactions (returns, refunds, rejects) are a large share of the processing.
The interoperability framework: the national ACHs (the Italian ICBPI and SIA systems, the Spanish Iberpay, the Portuguese SIBS, the German Bundesbank’s SEPA-Clearer) exchange their files with STEP2 and with each other under the EACHA interoperability framework, so that a SEPA payment reaches any bank in the area through at most two systems; the Eurosystem’s reachability policy and the ECB’s oversight of the systemic ones (STEP2, the French CORE) tie them together.
The batch model and the instant payments: a SEPA credit transfer in batch executes by the next business day (the SEPA Regulation’s D+1), which was the standard for twenty years; the instant credit transfer (ten seconds, any time) is replacing it as the Instant Payments Regulation makes it the default and no dearer, and the ACHs including STEP2 are moving their volumes to the instant rails (RT1, TIPS); the direct debits stay in batch for now.
EBA Clearing›RT1
RT1: the Instant Euro Payment Processed Within Seconds Around the Clock on Prefunded Positions Settled Through TIPS
EBA Clearing’s instant payment system: an instant payment or a request to pay from a merchant’s customer under the SCT Inst scheme with the verification of payee, the processing with the position check, the forward to the receiving PSP and the confirmation within seconds, the prefunded positions held on RT1’s technical account in TIPS in central bank money and managed from T2, the receiving PSP’s credit to the payee and the reach across RT1 and TIPS under the reachability measures and the Instant Payments Regulation, and the ECB’s oversight as a prominent system with the EPC’s scheme.
Worked example, illustrative:owner EBA Clearing, owned by its user banks; RT1 since November 2017; the positions in TIPS since the Eurosystem’s reachability measures of 2021 and 2022handles SEPA instant credit transfers and the request-to-pay, 24 hours a day; 3,000,000 a day, illustrative; 2,500 PSPs reachablemembers the participant PSPs with prefunded positions; the PSPs reachable through them; every TIPS participant through the linklinks TIPS for the technical account, the settlement in central bank money and the reach; T2 for the liquidity transfers during its hours; the EPC’s SCT Inst and request-to-pay schemesoverseen by the Eurosystem as a prominent retail payment system with the ECB as overseer; designated under the Settlement Finality Directive; the EPC for the scheme; the national authorities and the EBA for the PSPsthe day always open; the processing within seconds; the prefunding and withdrawals during T2’s hours; the balances held over the night and the weekend

The banks built the first pan-European instant system a year before the Eurosystem built TIPS, and the two now form one network: RT1 processes the ten-second payment against positions that sit in central bank money on a TIPS account, and a payee at any euro bank is reached through one or the other.
RT1 and TIPS: EBA Clearing launched RT1 in November 2017 as the first pan-European SCT Inst platform, settling on the participants’ prefunded positions held at the ECB through a TARGET2 technical account; the Eurosystem launched TIPS a year later and in 2020 decided that every instant ACH must move its technical account to TIPS and every TIPS-reachable PSP must be reachable in TIPS, so that the two systems and the national ones became one network with the finality in central bank money on TIPS.
The prominent payment systems: the Eurosystem’s oversight framework classifies the euro retail payment systems as systemically important (under the SIPS Regulation: STEP2, CORE(FR) and the others identified), prominently important (RT1 and the larger national systems, assessed against the CPMI-IOSCO principles in a lighter form) and the others; the classification sets the oversight’s intensity and the requirements on the system’s governance, risk and operations.
The request to pay: the EPC’s SEPA request-to-pay scheme (2021) lets a payee send a payment request to the payer’s bank app with the amount and the reference, which the payer approves and pays by an instant credit transfer, the European answer to the card at the point of sale and to the invoice in the mail; the banks and the fintechs build the merchant and the bill-payment services on it, with EPI (the European Payments Initiative’s Wero wallet) as the bank-owned brand since 2024.
The liquidity over the weekend: an instant system never closes but T2 does, so the participants prefund their positions before the Friday close for the weekend’s outflows and manage the balances with the inflows; a PSP that runs out cannot send until Monday’s T2 opening (or until it receives), which is the operational discipline the instant model imposes and the reason the balances count toward the minimum reserves to make the prefunding costless.
The Other Venues›Cboe Europe
Cboe Europe: the Pan-European Equity Venue From the Routed Order to the Lit and Periodic Auction Books, Cboe Clear Europe and the National CSDs
The pan-European MTF and its clearing house: an order for a French, German or Italian share routed by the broker’s smart order router across the venues under MiFID II, the match on the lit books, the periodic auctions, the dark book and the BIDS blocks, the reference prices from the listing exchanges’ auctions and the European best bid and offer with the consolidated tape coming, the trade to Cboe Clear Europe as the largest cash equity CCP under interoperability with the cross-venue netting and the settlement at the national CSDs on T2S, CEDX for the pan-European derivatives, and the AFM, DNB, ESMA and the home regulators.

A French share can trade on a Dutch MTF, clear at a Dutch clearing house and settle at the French depository on T2S: that is the market structure MiFID built, and Cboe Europe is its largest single venue and largest cash equity CCP. The listing exchange keeps the close; the MTF competes for the day.
The MTF competition: MiFID (2007) ended the exchanges’ concentration rules and let the multilateral trading facilities trade any EU share, and Chi-X, BATS, Turquoise and the others took a third of the European equity trading within five years on lower fees and faster technology; the exchanges kept the listings, the auctions and the closes, and the MTFs the continuous trading; Cboe Europe is the consolidation of that first wave, and Brexit split it into an EU and a UK entity.
The periodic auction books: after MiFID II’s double volume cap (2018) limited the dark trading under the reference price waiver, the venues launched frequent batch auctions (Cboe’s every 100 milliseconds) that match the orders at the midpoint-like price inside an auction, which the regulators treat as lit; they took the flow the dark books lost and are a standing subject of ESMA’s market structure reviews; the 2024 MiFIR review replaced the double cap by a single 7% cap.
Cboe Clear Europe: founded as EuroCCP in 2007 by Fortis and DTCC to clear the MTF trades, merged with the Dutch EMCF in 2013, owned by the exchanges and the banks, and bought by Cboe in 2020; it clears for the exchanges (Euronext, Xetra since October 2024, the LSE, the Nordic markets) and the MTFs under interoperability (the member choosing its CCP, the CCPs margining each other), nets the trades across every venue per ISIN and settles at 20 CSDs; the largest European cash equity CCP by trades cleared.
The consolidated tapes: MiFIR’s 2024 review created the EU consolidated tapes, one per asset class, with the provider selected by ESMA for five years; Ediphy (fairCT) was selected for the bonds in July 2025, EuroCTP (the exchanges’ joint venture) for the shares and ETFs in December 2025 and Etrading Software for the OTC derivatives in July 2026, with the tapes to go live after the authorizations; the equity tape carries the pre-trade best bid and offer and the trades of every venue, which the European market lacked since MiFID fragmented it.
The Bond and Swap Venues: the RFQ on Tradeweb EU, BTFE and MarketAxess NL, the Trading and Clearing Obligations, the Reports to the Repositories and the Tapes
The OTC venues after Brexit: a request for quote for a euro swap, a corporate bond or a Bund on the Amsterdam platforms, the dealers’ responses against the composites and the best execution record, the derivatives trading obligation and the clearing obligation sending the swap to Eurex Clearing or LCH Ltd within seconds with EMIR 3’s active account, the reports under EMIR Refit to the trade repositories, to the APAs and to the NCAs through the ARMs, the settlement of the cleared swap’s margin through T2, the bond at the CSD on T2S and the uncleared trades under the margin rules, and ESMA, the AFM, the NCAs, the consolidated tapes and the UK equivalence.

The buy side asks five dealers for a price, takes the best, and the swap is at a clearing house before the screen refreshes; the platforms moved to Amsterdam after Brexit, the swaps go to Frankfurt or London, and every trade is reported three ways. Not infrastructures themselves, but what the clearing houses and the repositories are fed by.
The venues after Brexit: Tradeweb, Bloomberg, MarketAxess and the interdealer brokers set up EU entities in Amsterdam and Paris in 2019 and 2020 so that the EU clients could keep trading under the EU trading obligations after the UK left, with the Dutch AFM as the home regulator of the RFQ platforms; the EU recognized the UK venues as equivalent for the derivatives trading obligation in 2021 to avoid the split of the swap market, and the two sets of venues serve the two client bases.
EMIR Refit reporting: the April 2024 rewrite of the EMIR trade reporting (the ISO 20022 XML messages, 203 fields, the global UTI and UPI, the critical data elements, the mandatory delegation rules, the reconciliation of the two counterparties’ reports and the error notifications) aligned the EU with the global standards after the CFTC’s 2022 rewrite and the UK’s of September 2024; the trade repositories registered with ESMA (DTCC Derivatives Repository Ireland, Regis-TR in Luxembourg, KDPW in Warsaw) hold the EU derivatives market.
The derivatives trading obligation: under MiFIR, the derivatives that are subject to the clearing obligation and sufficiently liquid must be traded on a regulated market, an MTF, an OTF or an equivalent third-country venue; ESMA’s standards cover the euro, dollar and sterling fixed-to-float swaps in the benchmark tenors, the overnight index swaps since the benchmark transition, and the iTraxx indexes; the post-trade risk reduction services (compression, rebalancing) are exempt since the 2024 review.
The active account and the basis: EMIR 3’s active account requirement (June 2025) obliges the EU firms above the thresholds to clear a representative share of their euro and zloty swaps and €STR futures at an EU CCP (Eurex Clearing, or CDSClear for the CDS), while LCH Ltd keeps most of the euro swap market under its tier 2 recognition to June 2028; the Eurex-LCH basis (a few basis points on the ten-year swap, illustrative) is the price of clearing in one house or the other, and the dealers run both.
CLS for the Euro: the Trades on T, the Pay-In Schedule, the Pay-Ins Through T2 to the ECB Account, Payment Versus Payment and the Pay-Outs
The euro in the FX settlement system: the euro FX trades submitted and matched by the settlement members on T, the pay-in schedule from the multilateral netting of each member’s positions, the pay-ins of the short euro positions through T2 to CLS’s account at the ECB in the 07:00 to 12:00 CET window, the settlement of each trade’s two legs together on CLS’s books subject to the risk tests, the pay-outs of the long positions through T2 until the account returns to zero, and the ECB in the CLS Oversight Committee as the central bank of issue of the euro under the Fed’s lead.

The euro legs of the world’s FX trades are paid into an account at the ECB through T2 in the European morning, settled against the dollars, the yen and the sterling on CLS’s own books so that neither leg moves without the other, and paid out again by noon. The ECB sits in the oversight committee for the euro, the Fed leads it.
The euro in CLS: the euro was one of the seven founding currencies of CLS in September 2002, and the ECB opened an account for CLS Bank in T2 (then TARGET) as the central bank of issue, the condition every currency’s central bank sets; the euro is on one side of about a third of the value CLS settles, second to the dollar, and the euro area’s banks are among the largest settlement members; the ECB’s surveys of FX settlement risk track the share of the euro trades settled through CLS or other payment-versus-payment arrangements.
The settlement window: the five hours from 07:00 to 12:00 CET are the only time of day when the RTGS systems of all 18 currencies are open at once (the Asia-Pacific systems late in their day, the Americas’ early), so the FX market’s settlement happens in the European morning and T2’s opening at 02:30 and the Eurosystem’s intraday credit supply the euro liquidity the pay-ins need; the Fed opened Fedwire at 21:00 ET for the same reason.
The Eurosystem’s location policy: the Eurosystem’s policy on the oversight and the location of the infrastructures settling the euro (2011, adjusted after Brexit) expects a system settling a significant share of the euro to be located in the euro area or subject to the Eurosystem’s oversight; CLS, outside the euro area, is accepted under the cooperative oversight arrangement with the ECB’s participation and the account at the ECB, the model the Eurosystem applies to the other global systems.
The cooperative oversight: the 2008 protocol under which the Federal Reserve, as CLS Bank’s primary supervisor, chairs the CLS Oversight Committee of the central banks of issue of the 18 currencies, which review the system’s risk management, the rule changes and the new currencies and services; the arrangement is the CPMI’s model for a multi-currency infrastructure, and the ECB sits in it for the euro as the Bank of England does for sterling and the Bank of Japan for the yen.
