The summary above is from the announcement ESMA published on October 25, 2026.

What the announcement says

With the publication of the RTS and ESMA Guidelines on standardised procedures and messaging protocols, the regulatory framework is now ready. The first deadline is for investment firms and their clients to comply with the new requirements on allocations and confirmations from 7 December 2026.

“The transition to T+1 is one of the most impactful recent market structure initiatives. It will fundamentally improve the efficiency and international competitiveness of the EU markets. The date is known, the roadmap is clear, and, with the final piece of regulatory guidance published today, the framework is now in place for all players in the trading and settlement chain to prepare for 11 October 2027.

A successful transition is a shared effort by the industry and the public authorities. The focus now shifts to market participants to comply with the regulatory requirements, ready their systems and processes, and test their preparedness for the change, considering the recommendations of the EU T+1 Industry Committee.”
