T+1: Community Testing and Buyer Protection Survey

With nearly one year to go until the European securities market transitions to a T+1 settlement cycle on October 11, 2027, the countdown has entered its final and most decisive phase. This milestone is the perfect moment to take stock, assess your operational readiness, and accelerate your testing preparations.

Clearstream has opened its T+1 Community Testing and Buyer Protection Survey, inviting clients to share their perspective ahead of the October 2027 go-live.

Why it matters

The T+1 transition will compress settlement timelines and introduce new operational requirements across instruction management, liquidity, corporate actions, and securities financing. Client input gathered through this survey will directly inform how Clearstream structures its testing support and industry coordination ahead of go-live.

Testing survey responses will shape the testing program and ensure client readiness efforts are appropriately supported. Community testing windows are structured across five phases between February and September 2027, covering core settlement functionalities, gating events, corporate actions scenarios, and end-to-end trade flows, while the Buyer Protection Survey gauges client interest and requirements for implementing automated buyer protection.
