Pillar 3 Data Hub Reporting

ARKK prepares your Pillar 3 disclosures for the EBA Data Hub, pulling prudential data from your existing systems, mapping it to the EBA taxonomy, and producing structured XBRL-CSV files ready for direct submission to the EBA via the EUCLID platform. Built-in validation checks every disclosure against the EBA's rules before anything leaves your team.

Banks still building Pillar 3 disclosures from PDFs and spreadsheets carry avoidable risk. The move from document-based reporting to structured, machine-readable data means manual formatting no longer holds up, and disclosures that do not reconcile with COREP and FINREP are exposed the moment they reach the Hub.

+ What is Pillar 3 Data Hub reporting?

The Pillar 3 Data Hub (P3DH) is a centralised EBA platform for collecting and publishing banks' prudential disclosures across the European Economic Area. Established under CRR Article 434a, it requires institutions to submit standardised XBRL-CSV disclosures covering risk, capital and sustainability factors, moving away from individual website publication to a single, machine-readable source.

+ How does ARKK support Pillar 3 Data Hub compliance?

ARKK's portal takes your prudential data and shapes it into conformant XBRL-CSV disclosures for the P3DH. DPM validation rules are applied against the EBA taxonomy before submission, and Excel-based templates plug straight into the workbooks your team already uses.

+ How long does it take to implement a Pillar 3 Data Hub solution?

Implementation depends on the disclosure templates in scope and the complexity of your existing data setup. Most institutions are operational well ahead of their next reference date, with our team providing hands-on support and the latest taxonomy packages throughout onboarding.

+ Does ARKK integrate with existing data systems?

Yes. The ARKK portal is source-agnostic, linking data from your existing workbooks, ERP or reporting systems, so figures stay consistent with your COREP and FINREP supervisory reporting rather than being rekeyed separately.

+ How is data secured on the ARKK platform?

ARKK's portal is ISO 27001 certified, with role-based access controls and an approval workflow, giving you a single secure destination for uploading, tracking and submitting your disclosures with a full audit trail.

+ What are the risks of managing Pillar 3 Data Hub reporting manually?

Manual disclosure makes it easy to miss CRR3 template changes, misalign figures with your supervisory reporting, or fall behind the latest ESG, equity and shadow banking updates. With disclosures published publicly by the EBA, a single inconsistency is visible to investors, analysts and supervisors alike.
