T+1 Settlement: are firms ready for 2027?
AI Analysis
The FCA published an update on market readiness for the UK’s move to a T+1 securities settlement cycle on 11 October 2027, based on ongoing engagement with buy-side and sell-side firms, market infrastructures, trade associations and third-party providers. The message is clear: many firms are on track, but some are materially behind, and the FCA said it may take action and will supervise more intrusively as the deadline approaches.
Key dates
- 2026-12-31 Deadline
- AST critical recommendations expected to be implemented, including same-day trade allocation/confirmation and adoption of the FMSB SSI standard
- 2027-10-11 Deadline
- UK T+1 securities settlement cycle begins; transferables securities traded on a UK venue and settled on a UK CSD are expected to settle on T+1 basis
Suggested considerations
- Review whether the firm has completed a T+1 project plan, secured budget and governance, and mapped all required system and process changes.
- Check that trade allocation and confirmation processes can operate by end of trade date, or identify remediation needed to reach that standard.
- Confirm adoption of the FMSB standard for sharing standard settlement instructions and align client outreach to ensure clients use the same standard where relevant.
- Assess whether current settlement performance can be measured clearly, including failure rates and root causes, and whether management information is sufficient to track progress.
- Validate dependencies on custodians, counterparties, clients and third-party providers, and obtain their implementation timelines and testing plans.
- Prepare testing strategy and evidence for testing readiness, including alignment with the UK/EU joint testing plan.
- Consider whether the firm’s fund settlement cycle should move to T+2 before 11 October 2027 to reduce cycle mismatch risk.
- Increase automation where manual processes remain material, particularly in matching, confirmation and settlement instruction workflows.
What changed
This is not a new rule notice, but it is a supervisory signal about expectations for the 11 October 2027 T+1 transition. The FCA expects firms to have completed T+1 project planning, secured budget and governance, and be well into implementation, with system and process changes underway and testing plans finalised by the time the market moves closer to 2027. The FCA highlighted specific implementation priorities drawn from the Accelerated Settlement Taskforce framework, including allocating and confirming trades by the end of trade date, adopting the Financial Markets Standards Board standard for sharing standard settlement instructions, and preparing to test changes against the UK/EU joint testing plan. It also expects firms to understand and monitor their own settlement failure rates an
Compliance impact
The FCA made clear that lack of readiness is a systemic risk, not just a firm-specific issue, and said it may take action where firms are not prepared. It also warned that supervision will become increasingly intrusive as October 2027 approaches, with expectations for clear evidence of implementation and testing progress.
