Executive Summary

ESMA has issued a statement urging EU market participants to prioritise implementation work for the EU move to a T+1 settlement cycle on 11 October 2027. ESMA states that readiness surveys show awareness and commitment are improving, but implementation remains uneven across markets, sectors and firms. The statement confirms two key compliance milestones: 7 December 2026 for improvements to allocation and confirmation processes, including timing and default use of international communication standards, and 11 October 2027 for settlement-layer requirements, including earlier settlement instructions and wider use of CSD functionalities such as auto-partial settlement, hold and release, and auto-collateralisation. ESMA also notes that amendments to Commission Delegated Regulation (EU) 2018/1229 have been endorsed by the European Commission and are under scrutiny by the European Parliament and Council. Firms should treat this as a high-priority implementation and ecosystem-readiness issue, with operational, reputational and counterparty risks if preparations lag.
