UK Taskforce Sets T+1 Settlement Target for Oct. 11, 2027 Go-Live

1 articles · Updated · Markets Media · May 29

The Accelerated Settlement Taskforce said post-transition performance will be judged against the market’s average settlement rate in July, August and September 2027, rather than a fixed theoretical benchmark.
That target is meant to prevent a rise in settlement fails after the UK shifts to T+1 on Oct. 11, 2027, and to keep market efficiency at current T+2 levels.
Starting in 2027, the taskforce will publish a rolling 3-month average using CREST data so firms can track the benchmark ahead of the deadline.
The approach follows Recommendation SETT04 in the taskforce’s 2025 final report, which anchored expectations in real-world market performance.
Chair Andrew Douglas said firms should act now on the February 2025 implementation plan, with automation critical to meeting shorter settlement deadlines.
