On 26 May 2026, the European Securities and Markets Authority (ESMA) published a consultation paper proposing amendments to the Guidelines on standardised procedures and messaging protocols under the Central Securities Depositories Regulation (CSDR). The document seeks stakeholder feedback on proposed changes aimed at enhancing the efficiency and harmonisation of settlement processes across the EU, directly impacting CSDs, investment firms, and market infrastructure operators.
The consultation paper, issued by ESMA's Markets and Market Infrastructures unit, outlines revisions to the existing guidelines that govern how CSDs and other market participants communicate and process settlement instructions. The amendments focus on updating messaging standards, clarifying procedures for fails management, and aligning with evolving market practices and technological developments. ESMA invites comments from all interested parties, including CSDs, banks, investment firms, and trade associations, by the deadline specified in the document.
Policy orientations and trade-offs
The proposed amendments aim to reduce operational risks and improve settlement efficiency by standardising messaging protocols and procedures. However, they may impose compliance costs on market participants who need to update their systems and processes. ESMA seeks to balance harmonisation benefits against the burden of implementation, particularly for smaller CSDs and firms. The consultation also touches on the trade-off between flexibility for national practices and the need for uniform EU-wide standards.
Impact on stakeholders
- Central Securities Depositories (CSDs): Will need to adapt their messaging systems and procedures to comply with updated guidelines, potentially incurring IT and operational costs. Positive impact from reduced fragmentation and improved cross-border settlement.
- Investment firms and banks: May benefit from streamlined processes and reduced settlement fails, but face initial adaptation costs for updating internal systems and training staff.
- Market infrastructure operators: Could see improved interoperability and reduced risk, but may need to coordinate with multiple CSDs to ensure compliance.
- EU regulators and policymakers: Gain from enhanced oversight and data consistency, supporting financial stability objectives.
Expected institutional follow-up
Following the consultation period, ESMA will analyse responses and publish a final report with the revised guidelines. The European Commission and other EU institutions may subsequently consider legislative or regulatory adjustments to CSDR if the guidelines reveal broader policy needs. Market participants are encouraged to submit feedback to shape the final outcome.
