Accelerated settlement will affect markets in different ways. Local practices, sub-custody arrangements, cut-off times, and domestic workflows vary across jurisdictions – and timelines become tighter with T+1.
For this reason, Nasdaq CSD’s preparations focus on challenges specific to the Baltic and Icelandic markets, tailoring readiness efforts to participants’ needs and local conditions.
Like other European market infrastructures, Nasdaq CSD is adjusting its operations for a shorter settlement cycle.
We are committed to supporting our participants and markets to ensure a seamless transition.
The EU T+1 Industry Committee plays a central role in guiding the transition to a shortened settlement cycle.
The EU T+1 High Level Roadmap, published in summer 2025, includes 58 recommendations to support market participants in their analysis and planning for T+1. The recommendations were developed by stakeholders across the financial sector. They are not legally binding, but are strongly recommended.
Commission Delegated Regulation (EU) 2026/1536, which amends the existing Settlement Discipline RTS (EU) 2018/1229, was published in the Official Journal of the European Union on 14 October 2026. The regulation has not been incorporated into the EEA Agreement and is therefore not yet applicable in Iceland.
The Regulation introduces several changes aimed at improving settlement efficiency and supporting the transition to T+1, including amendments related to settlement instructions, partial settlement, and settlement fails reporting.
The new requirements will apply progressively from 7 December 2026, 1 July 2027, and 11 October 2027.

The EU, UK and Switzerland have published a joint Testing and Readiness Plan for the move to T+1 settlement, setting out how market participants should prepare for the October 2027 transition.
In addition, the EU T+1 Industry Committee has published a comprehensive readiness checklist that translates the High-Level Road Map recommendations and related technical work into actionable considerations across the trade lifecycle. Market participants are encouraged to review the checklist, assess the relevance of each item to their operations, and determine any necessary actions to support their readiness for the transition.
More information is available on the committee’s website:
https://eu-t1.eu/, including a dedicated Q&A section.
Nasdaq CSD will provide further information to its participants, including details on key changes and testing plans.
All information will be published in the Participants’ Secure Portal.
