The T+1 Transition Priorities

A Practical Playbook for Meeting European T+1 Settlement Requirements

Europe’s move to T+1 will fundamentally reshape post-trade operations. This white paper explains what breaks first, where risk concentrates, and how firms can prepare.

The EU, UK and Switzerland will move to T+1 settlement on October 11th, 2027. The compressed cycle cuts the time available for affirmation, funding, and reconciliation by at least half.

Equilend analysis shows that trades booked T+2 today achieve only a 65.5% match rate by the end of T+1. Without changes to automation, pre-matching and real-time visibility, firms should expect settlement fails to rise sharply once T+1 is live.

This white paper provides a concrete readiness plan tailored to the complexity of European markets, which includes multiple CSDs, CCPs, currencies, and cross-border settlement models.
