On 14 October 2026, Commission Delegated Regulation (EU) 2026/1536 of 6 July 2026 (the Amending Regulation) was published in the Official Journal. The Amending Regulation amends the regulatory technical standards laid down in Commission Delegated Regulation (EU) 2018/1229 of 25 May 2018 on settlement discipline (the Settlement Discipline RTS) to improve settlement efficiency and facilitate the transition to a shorter settlement cycle (T+1). Furthermore, on 16 October 2026, ESMA published a final report containing revised guidelines (the Guidelines) on standardised procedures and messaging protocols. The revised Guidelines also support the EU’s transition to a T+1 settlement and promote greater automation across post-trade processes.
