Pillar 3 Data Hub (P3DH)

What is Pillar 3 Data Hub (P3DH)?

The Pillar 3 Data Hub (P3DH) is a centralised digital platform developed by the European Banking Authority (EBA) to publish prudential disclosures by credit institutions across the European Economic Area (EEA). The P3DH initiative aims to move away from institution-specific web publication and establish the EBA as the central access point for prudential disclosures. In the coming years, P3DH data will also feed into the European Single Access Point (ESAP), further improving accessibility for investors, analysts, and the public.

Its implementation responds to new mandates introduced under the Capital Requirements Regulation (CRR 3, Regulation (EU) 2024/1623) and Capital Requirements Directive (CRD VI, Directive (EU) 2024/1619), as part of the EU’s effort to enhance transparency, comparability, and accessibility of regulatory disclosures within the banking sector.

Impact Analysis

Who is Impacted?

Large and other relevant credit institutions across the EEA, as defined under CRR III.

Scope of Impact

• Introduction of a centralised publication process via the EBA, replacing institution-specific web disclosure.
• Mandatory use of XBRL-CSV and data-extractable PDF formats for submission.
• Expanded disclosure content across 22 thematic areas aligned with DPM 4.1.
• Requirement to ensure internal system readiness, taxonomy compliance, and data quality validation.
• Reinforced governance through management-level sign-off of submitted data.
• Dual publication window from June to December 2025, with P3DH becoming the sole channel from March 2026.

Voluntary disclosures

As part of the initial rollout, institutions may also voluntarily disclose information on MREL and TLAC, although this is not required under the ITS. These additional disclosures can enhance market transparency on resolution planning and loss-absorbing capacity.

What is the implementation timeline?

Effective date and transition period

From 30 June 2025, large and relevant institutions must submit Pillar 3 disclosures to the P3DH in a structured, machine-readable XBRL-CSV format, accompanied by data-extractable PDFs for narrative elements. 

The first P3DH reporting date aligns with the launch of DPM 4.1 under CRR III, introducing major updates on credit risk (standardised and internal models), operational risk, CVA templates, ESG disclosures, and guidance on crypto-asset exposures.

The platform includes a transition period from June to December 2025, during which institutions may continue their existing publication practices in parallel. From March 2026, use of the P3DH becomes mandatory for all applicable institutions.
