The European Securities and Markets Authority has published a final report recommending significant amendments to the Regulatory Technical Standards (RTS) on settlement discipline to improve settlement efficiency across the EU, support the move to a shorter settlement cycle (T+1) by 11 October 2027, and reduce administrative burden for central securities depositories (CSDs) and market participants. The proposed package includes same-day timing (trade date) for trade allocations and settlement instructions, machine-readable formats for allocations and confirmations, mandatory implementation of hold and release, auto-partial settlement and auto-collateralisation functionalities, and updated rules for monitoring and reporting settlement fails. Implementation would be phased in from December 2026 and completed by 11 October 2027, with ESMA urging market infrastructures, intermediaries and their clients to build these changes into their T+1 transition plans. The draft RTS amendments have been submitted to the European Commission, which has three months to decide whether to adopt them.
