Europe’s move to T+1 settlement by October 2027 represents far more than a post-trade timeline change. It is a structural transformation that will reshape front-to-back operating models across capital markets — from trading and treasury to technology, risk, liquidity, and client engagement.
In this ebook we explore why the European T+1 transition is fundamentally different from the US experience, and why success will depend on enterprise-wide transformation, not tactical fixes.
Drawing on regulatory guidance, industry insights, and lessons learned from the US T+1 implementation, this paper outlines the operational, financial, and governance challenges firms must address to achieve resilient, scalable, and compliant T+1 settlement.
