Basel III Reporting & Supervisory Reporting for Banks

Under Basel III and CRR III, banks must fulfill extensive reporting obligations: COREP submissions on own funds, large exposures, and leverage ratio, FINREP submissions for financial reporting, liquidity metrics (LCR and NSFR), and Pillar 3 disclosures. Since 2025, CRR III introduces additional requirements including the output floor, revised credit risk standardized approaches, and ESG reporting obligations.

COREP (Common Reporting) covers the supervisory reporting of own funds, capital requirements, large exposures, leverage ratio, and liquidity metrics to supervisory authorities such as the EBA. FINREP (Financial Reporting) concerns standardized financial reporting under IFRS or national accounting standards. Both reporting frameworks are closely interconnected under CRR III and require consistent data foundations.

ADVISORI implements automated data extraction and calculation pipelines that consolidate your heterogeneous data sources and generate COREP/FINREP-compliant submissions. Through multi-level validation rules, automatic plausibility checks, and workflow orchestration, we reduce manual interventions by up to 70% and significantly shorten reporting cycles.

CRR III introduces significant changes: the output floor limits internal model relief to 72.5% of standardized approaches, requiring new calculations and reporting obligations. Additionally, revised reporting templates for credit risk, operational risk, and CVA risk, expanded ESG disclosure requirements, and new reporting forms for crypto exposures have been introduced. The first CRR III reporting submission was due on March 31, 2025.

Data quality is the critical success factor for reliable regulatory reporting. Incorrect or inconsistent data leads to wrong own funds calculations, supervisory objections, and reputational risks. Our procedure establishes a data governance framework with automated data quality checks, reconciliation rules between source systems and reporting data, and complete data lineage from source records to the final submission.

Pillar 3 disclosure requires banks to regularly publish information on risk management, capital adequacy, and risk positions. Since CRR III, this also includes ESG risk information. Disclosures are made semi-annually or quarterly depending on institution size and include standardized tables and templates according to EBA implementing technical standards.

An integrated procedure consolidates COREP, FINREP, Pillar 3, and liquidity reporting on a shared data platform. This eliminates data silos, reduces reconciliation efforts, and enables consistent submissions across all reporting frameworks. Additionally, management reports and strategic analyses can be derived directly from regulatory data, transforming reporting from a cost center into a strategic management tool.
