The European Securities and Markets Authority has published its annual report on the quality and use of regulatory data, finding measurable improvements across major datasets including EMIR, SFTR, MiFIR, AIFMD and MMFR. The report also points to wider use of those datasets by ESMA and national competent authorities, linking better data quality to more effective supervision and market monitoring across the EU. This edition expands the scope of the review to additional reporting regimes and registers, including Prospectus reporting and major ICT-related incident reporting under the Digital Operational Resilience Act. It also highlights ESMA's simplification work in 2025, including a Call for Evidence on streamlining reporting under EMIR, MiFIR and SFTR through options such as removing duplications or applying a report once approach, and ongoing development of an integrated reporting framework for investment funds to harmonise requirements and reduce fragmentation. Alongside this, ESMA is increasing automation, advanced analytics and shared tools and dashboards with national competent authorities as part of its broader data strategy. ESMA will hold a webinar on 18 June to present the report's main findings.
