T+1: Europe Takes a Major Step Forward
After the United States and Canada last year, Europe is preparing to adopt settlement in T+1 under the CSDR (Central Securities Depositories Regulation). This change marks a significant turning point for financial markets and their participants. The goal is clear: to harmonize international standards and reduce risks associated with transaction settlement. The United Kingdom and Switzerland are moving to the same T+1 cycle on the same date, reinforcing global alignment of settlement practices.
A Timeline Already Defined
The Level 1 EU legislative text of CSDR, together with the Level 2 measures on settlement discipline, has progressed further. A final report on amendments to RTS was published on 13 October 2025. The European Commission has since adopted the corresponding Delegated Regulation (C(2026) 4640 of 6 July 2026), now under scrutiny by the European Parliament and the Council, confirming the implementation date of 11 October 2027.
To support this transition, the EU T+1 Industry Committee published its Industry Handbook, detailing operational impacts and recommendations, in February 2026. Provisions related to allocations, confirmations, and settlement instructions will apply starting December 7, 2026.
The market identifier code (MIC) requirement follows on 1 July 2027. In parallel, ESMA and national regulators are finalizing Level 3 guidance on allocations and confirmations to give the industry a clear, common basis for compliance.
What This Means
Moving to T+1 shortens the settlement cycle by one day for securities traded on a trading venue. This shortening requires full automation of processes; all manual intervention must therefore be eliminated. Allocations and confirmations must be sent before 11:00 p.m. at T to ensure everything is completed on time, and settlement instructions must be sent before 11:59 p.m. to the CSD in a standardized and machine-readable format so they can be processed on T+1. New fields such as PSET (place of settlement) and MIC (market identifier) must be included in messages to ensure fast and compliant settlement.
Although securities financing transactions (SFT*s) are not directly required to move to T+1, further clarifications have since been given to help related settlement flows keep pace with the shorter timeframe: dedicated mechanisms are being introduced to better synchronise repo and securities-lending settlement with the underlying market activity, and lending desks are expected to confirm transactions in real time rather than through end-of-day batches.

During the Transition to T+1
Cash penalties will continue to apply throughout the T+1 transition: no blanket suspension is planned. The European Commission does, however, retain the power to temporarily suspend penalties if it detects a significant spike in settlement fails linked to the switch, a safeguard that underlines the complexity and importance of this regulatory change.
Impacts for Management Companies and Fund Administrators
Management companies must analyze each fund individually to decide whether subscription and redemption cycles should be aligned with T+1. This assessment is critical to avoid asset–liability mismatches and liquidity stress.
The industry continues to push for cash breaches caused by settlement misalignment to be treated as passive, non-reportable breaches; the EU T+1 Industry Handbook (February 2026) is now seeking regulatory clarification by the end of 2026.
If alignment is required, it becomes more challenging for both the management company and the fund administrator. NAV calculation and transmission must be completed much faster, with delivery no later than 9:30 a.m. on T+1 and validation by the management company before 12:00 p.m., so that subscriptions and redemptions made the previous day can be processed by the transfer agency in the afternoon of T+1. This acceleration reduces the margin for quality checks and requires robust automation.
