The European Banking Authority (EBA) has finalized the implementing standards for the Pillar 3 Data Hub (P3DH), which will centralize prudential disclosures of banks and make this data publicly available through a single electronic access point. This initiative is expected to have significant strategic implications for banks and other market participants.

The standards provide technical details and timelines that institutions must follow when submitting their Pillar 3 disclosures. The Hub will feature API-enabled data downloads and data visualization tools, allowing comparisons across institutions, countries, and portfolios in a standardized format. Key dates include June 30, 2025, as the first disclosure reference date for large institutions, while small and non-complex institutions (SNCIs) will follow on December 31, 2025.

Standards specific to SNCIs and the resubmission policy are set to be proposed separately in the first half of 2025. The P3DH mandate is part of the Banking Package (CRR3/CRD6) aligned with Basel III reforms in the EU.

The EBA P3DH links with the European Single Access Platform (ESAP), an EU project designed to centralize public information disclosure within the EU single market. The EBA plans to integrate Pillar 3 information into ESAP by 2030.

An onboarding plan will be released with reporting framework version 4.1 during Q1 of 2025. It will include onboarding information for large institutions, identification system confirmation for submissions, and go-live dates corresponding to reference dates in June, September, and December of 2025.

This centralization initiative aims to enhance regulatory oversight of banking sector health, systemic risk assessment, and compliance enforcement regarding capital requirements. Banks are encouraged to develop robust data governance frameworks for accurate reporting despite potential initial challenges. The long-term benefits include increased efficiency, automation, data consistency, and transparency.

With the June 2025 deadline nearing, banks should begin formulating their implementation plans immediately. Quantitative data submissions to the EBA Data Hub will require XBRL-csv format adherence alongside automated reporting solutions that align with BCBS 239 principles for risk data aggregation.
