Europe launches coordinated T+1 testing programme

The EU, UK, and Switzerland have published a joint Testing and Readiness Plan for the move to T+1 settlement, outlining how market participants should prepare for the October 2027 transition.
The plan, issued by the EU T+1 Industry Committee, the UK Accelerated Settlement Taskforce and the Swiss Securities Post Trade Council, is the first coordinated testing framework across the three markets. It follows the creation of a joint workstream in December 2025 and reflects what the authors describe as a “high degree of cross-market participation” across the region.
