Exchanges, Clearing & Settlement
Explore the infrastructure behind global financial markets, from trading venues and clearing houses to securities settlement, custody and market technology.
Follow developments in exchange operations, central counterparty clearing, post-trade processing and settlement systems, and read who may be affected. A planned launch stays planned. A consultation stays a consultation. Industry research is not rewritten as a statute.
The review date is an editorial pass of this page. It is not a live check of every venue. Each briefing has its own WiT Markets date. Each document has its own source date. 7 developments are on this file, including the ESMA T+1 note that also sits on the regulatory desk.

DTCC research sets out operational strains ahead of Europe’s T+1 move
On 21 October 2026 DTCC and ValueExchange published research on fragmented post-trade workflows ahead of Europe’s move to T+1. The figures are the report’s findings. They are not a legal requirement.
Why it matters. Brokers, custodians and settlement operators can see which operational gaps the research names before the settlement day shortens. The gaps are about data, matching and instructions. They are not a new statute.

Counts are the briefings on this file. An empty count is a gap in the file, not a claim that the subject has no rules.
Exchanges and trading venues
Where an order can be matched: stock and futures exchanges, alternative venues, listings, sessions, halts and venue rules.
Central clearing
How a central counterparty calculates obligations, collects margin and handles a member default. Clearing is not the transfer of the security.
Settlement and custody
How securities and cash move after a trade, including depositories, custodians, settlement finality and fails.
Trading technology
Messaging, market data, allocation, confirmation and the operational systems that connect a venue to post-trade processing.
Digital market infrastructure
Tokenised securities, tokenised collateral and distributed-ledger arrangements that a supervisor has actually asked about.
Market regulation and resilience
Implementation dates, supervisory statements and resolution planning for critical infrastructure. A rehearsal is not an outage.
From order to settlement: the trade lifecycle
Select a stage. The notes describe a securities trade on an exchange that uses a central counterparty and a depository. They are not a map of every product.
Order submission
Participants. The client and the broker or other intermediary that accepts the order.
Purpose. Turn an instruction into an order the venue can receive.
What can go wrong. The order can be rejected, routed to a different venue, or filled only in part.
Typical process. The firm checks the account, the instrument and the order type, then sends the instruction on.
No briefing in this file is tagged to this stage.
This sequence is a representative exchange-traded securities trade. An over-the-counter contract, a futures trade, a bilateral settlement, a CFD and a cryptoasset transfer do not all pass through the same rooms. A CFD is a contract with the provider. It is not delivery of the share at a depository.
Clearing and settlement are not the same process
Execution matches the orders. Clearing works out the obligations and the collateral. Settlement transfers the securities and the cash. A match is not ownership.
| Question | Clearing | Settlement |
|---|---|---|
| What is determined | Who owes what after the trade, including net amounts where the rules allow netting. | Which account delivers securities and which account pays or receives cash. |
| Who is in the middle | A central counterparty, where the market uses one. Some trades stay bilateral and never face a clearing house. | A central securities depository, custodians and a cash payment system. |
| Collateral | Initial margin, variation margin and, for members, default-fund resources. | The securities and the cash that have to be in place on the settlement day. |
| What “done” means | Obligations are calculated and margin is called. The security may still not have moved. | The depository’s rules say the transfer is final. That point is later than the trade confirmation. |
Execution is not clearing, and clearing is not settlement. A CFD closes against the provider. A futures contract is margined and expires. A cryptoasset transfer follows the network’s own record. None of those is this securities diagram by default.
Important infrastructure dates
Dates stated in the documents. A planned company launch is labelled differently from a compliance date and from a consultation deadline.
Mandatory requirementEuropean UnionESMA
EU allocation and confirmation requirements
ESMA said investment firms and their clients are to comply with new allocation and confirmation requirements from 7 December 2026. This date is not the day the settlement cycle changes.
Planned launchUnited StatesCME Group
CME Securities Clearing’s announced launch date
CME Group said on 10 September 2026 that it plans to launch the service on 7 December 2026, pending necessary regulatory approvals. A planned launch is not a legal mandate, and it is not a statement that the service is operating.
Compliance dateUnited StatesSEC
Eligible US Treasury cash transactions
The SEC’s 25 February 2025 release extended the compliance date for eligible cash-market transactions to 31 December 2026. The obligation is on covered clearing agencies and the eligible secondary-market transactions of their direct participants. It is not a rule for every Treasury trade.
Consultation deadlineEuropean UnionESMA
Tokenised collateral call for evidence closes
ESMA asked for contributions by 15 January 2027. A call for evidence is not approval of tokenised collateral for EU central clearing.
Scheduled end of a transitional regimeEuropean UnionESMA
Third-country CSD transitional regime is scheduled to end
ESMA said the current transitional regime is set to end on 17 January 2027. Its 7 October 2026 statement says EU participants should not be prevented from access while legislation to extend the regime is still under negotiation. The statement is not that extension.
Compliance dateUnited StatesSEC
Eligible US Treasury repo transactions
The same 25 February 2025 SEC release extended the compliance date for eligible repo transactions to 30 June 2027. Scope remains the eligible transactions described in the rule.
Scheduled transitionEuropean UnionESMA
EU securities settlement moves to T+1
ESMA said the EU switches to T+1 settlement on 11 October 2027. This is the settlement-cycle date, separate from the 7 December 2026 messaging requirements.

How to read the themes
Context for the documents above. These notes are not forecasts and they do not add figures.
Faster settlement
A shorter cycle leaves less time to allocate a trade, confirm it, fund it and deliver it. The EU dates in this file keep the December 2026 messaging step separate from the October 2027 settlement step.
Central clearing expansion
A clearing mandate changes who must face a central counterparty, and for which transactions. The US Treasury dates apply to eligible transactions of direct participants at a covered clearing agency.
Clearing-house resilience
Default management is how a central counterparty continues if a member fails. The US-UK readout in this file is a rehearsal of coordination. It is not a report of a failure.
Cross-border settlement
A security constituted under one country’s law can be recorded at a depository in another. The ESMA statement on third-country depositories is about access during a legislative gap. It is not the extending statute.
Tokenisation
Representing collateral on a ledger raises questions of enforceability, segregation and whether the asset can be turned into cash in a default. ESMA has asked those questions. It has not approved a token as margin.
Market infrastructure reference
Short definitions for this page. Where WiT Markets already has a glossary entry, the term links to it. New glossary routes were not added.
Trading venue
A system where orders can meet under published rules. An exchange is one kind of venue. Other venues match orders without being the listing exchange.
Exchange
A trading venue that lists standardised contracts or securities and sets session, halt and membership rules.
Clearing house
The organisation that operates central clearing. In many markets it is also the central counterparty.
Central counterparty
A clearing house that becomes the buyer to every seller and the seller to every buyer, when the market’s rules provide for that.
Clearing member
A firm that faces the central counterparty directly. Clients often reach the clearing house through a member.
Initial margin
Collateral collected at the start of a cleared position to cover a defined range of price moves.
Variation margin
Collateral collected or returned as the cleared position’s value changes. It is not a fee.
Default fund
A pool of resources clearing members contribute so the clearing house can cover a member default beyond the defaulter’s own margin.
Central securities depository
The system that keeps the official record of who holds which securities and that operates the settlement of those securities.
Custodian
A firm that holds securities for a client and sends settlement instructions. The custodian’s statement is the client’s view of an account.
Securities settlement
The transfer of securities against payment after a trade. It is later than the match, and it is a different step from clearing.
Delivery versus payment
A settlement method in which the securities move only if the cash moves. It reduces the chance that one side delivers and receives nothing.
Settlement finality
The point at which the rules say a transfer can no longer be unwound. A trade confirmation is earlier than that point.
Settlement fail
A settlement that does not complete on the intended day, often because securities or cash were not available. The trade can still exist.
T+1
A settlement cycle in which securities are due to settle one business day after the trade date. The EU date stated by ESMA is 11 October 2027.
Repo
A sale of securities with an agreement to buy them back. In the US Treasury rule, eligible repo has its own later compliance date.
Collateral
Assets posted to support an obligation. At a clearing house, collateral includes margin. Tokenised collateral is the subject of an ESMA call for evidence, not an approval.
Netting
Combining offsetting obligations so that a smaller amount is settled or margined. Netting follows the rules of the clearing house or the contract. It is not automatic for every product.

News methodology
How a source date is kept apart from the WiT Markets date.
How these briefings are checked
An infrastructure item starts from a regulator, a public authority, or the infrastructure company’s own notice. The documents for the briefings on this page were read on 22 October 2026. That check date is on the source record. It is not a claim that a venue was watched after that day.
Industry research is labelled as research. A planned launch stays planned until a later notice says the service is operating. A call for evidence is not an approval. A supervisory statement is not the statute it discusses. A tabletop exercise is not an outage. A compliance date applies to the transactions and participants named in the rule.
The briefing date is the day WiT Markets published the note. The source date is the day on the document. Company figures, including savings and volume changes, stay attributed to the company or the research. They are not remeasured here. The ESMA T+1 briefing was already published on the regulatory desk. It is listed here as well, rather than rewritten as a second article.
