European Union (EU), United Kingdom (UK), and Switzerland (CH) T+1 Testing Plan
The T+1 Testing Plan is a joint initiative and publication from the EU T+1 Industry Committee, UK Accelerated Settlement Taskforce and Swiss Securities Post-Trade Council to outline a collective industry framework around testing for T+1 settlement.
The report focuses on testing logistics and timelines, different testing touchpoints and scenarios and encourages firms of all sizes to undertake an analysis of their own metrics with a view to de-risking the transition.
T+1 Industry Testing Plan V2
As of September 2026, the industry testing plan has been updated to include information that had been pending at the time of publication in March 2026.
This includes T2S Governance confirmation on testing accessibility, broader metrics inclusion and a link to the AMI-SeCo CEG’s proposed Corporate Action testing scenarios.
