The European Securities and Markets Authority (ESMA) published a final report on 4 May 2026 outlining plans for an integrated collection of data from investment funds across the EU. The report, issued by ESMA's Investment Management Unit, aims to streamline reporting requirements for fund managers and enhance the quality and comparability of data available to regulators and investors.

The final report proposes a harmonised framework for collecting data on fund holdings, performance, and risk metrics. While the recommendations are not legally binding, they are expected to inform future legislative proposals from the European Commission. The report sets no concrete numerical targets but calls for a phased implementation starting in 2027.

Policy orientations and trade-offs The report balances two competing objectives: reducing the administrative burden on fund managers by standardising reporting templates, and increasing the granularity of data for supervisory purposes. ESMA argues that a single EU-wide reporting system would cut compliance costs for cross-border fund operators, but acknowledges that smaller national fund managers may face upfront adaptation costs. The report also weighs investor protection against market efficiency, recommending more frequent disclosure of portfolio data to improve transparency, while cautioning that overly detailed public reporting could reveal proprietary trading strategies.

Impact on stakeholders Fund managers, particularly those operating in multiple member states, stand to benefit from reduced duplication of reporting. However, smaller firms may struggle with the initial investment in new IT systems. National competent authorities will gain access to more consistent data, enabling better cross-border oversight. Investors could see improved comparability of fund performance and risk, aiding informed decision-making. ESMA itself will assume a central coordination role, potentially increasing its influence over fund supervision.

Expected institutional follow-up The European Commission is expected to use the report as a basis for a legislative proposal on fund data harmonisation, possibly in early 2027. The European Parliament and Council will then debate the proposal, with industry stakeholders likely to lobby for extended transition periods and cost-sharing mechanisms.
