T+1 Settlement Is Coming: How UK and EU Financial Institutions Can Prepare Now
Key challenges
The shift to T+1 compresses the time between trade execution and final settlement from two days to one. This tighter window leaves far less room for error, delay, or manual intervention.
The UK Accelerated Settlement Taskforce (AST) and the European Securities and Markets Authority (ESMA) has recommended 11th October 2027 for the optimal date for T+1 adoption.
The AST’s recommendations identify three critical areas for automation:
- Standard Settlement Instructions (SSIs) YES
- Corporate Actions
- Stock Lending Recalls
For financial institutions in the UK and EU, these priorities should serve as a roadmap.
