COREP

COREP began with the goal to improve financial transparency and harmonize prudential supervision across Europe. EU legislators first introduced the Capital Requirements Directive IV (CRD IV) and the Capital Requirements Regulation (CRR), which came into effect on January 1, 2014. These regulations established standardized supervisory reporting frameworks, including Common Reporting (COREP) and Financial Reporting (FINREP), under the oversight of the European Banking Authority (EBA). 

COREP focuses specifically on capital adequacy and risk exposure, requiring institutions to report detailed information on: 

• Credit risk 
• Market risk 
• Operational risk 
• Own funds 
• Capital adequacy ratios 

Today, COREP aims to achieve the following five objectives: 

1. Assessments on capital adequacy 
   Enable regulators to determine whether financial institutions hold sufficient capital relative to their risk profiles and comply with minimum prudential requirements. 
2. Standardize supervisory reporting across Europe 
   Replace fragmented national reporting requirements with harmonized templates and definitions, improving consistency across EU and EEA jurisdictions. 
3. Enable centralized supervisory data collection 
   Support the aggregation of banking data across borders, improving regulators’ ability to monitor institutions operating in multiple jurisdictions. 
4. Improve risk analysis and comparability 
   Provide standardized, high-quality data that allows regulators to analyze trends, conduct peer comparisons, assess systemic risk, and gain an apples-to-apples view of institutions. 
5. Facilitate data sharing among supervisory authorities
   Enable efficient information sharing between national competent authorities, supervisory colleges, the European Systemic Risk Board (ESRB), and the European Supervisory Authorities (ESAs). 

Common reporting standards are harmonized regulatory rules, templates, and definitions designed to ensure consistent supervisory reporting across institutions and jurisdictions.

Under COREP, credit institutions and CRR-regulated investment firms operating in EU and EEA jurisdictions are required to submit standardized supervisory data to their National Competent Authority (NCA). Reporting is conducted primarily on a quarterly basis, with certain templates required monthly, depending on the institution’s size, risk profile, and regulatory requirements. 

COREP comprises multiple reporting modules covering key prudential areas, including: 

• Group solvency and large exposures 
• Market risk 
• Capital adequacy 
• Credit risk 
• Operational risk 

COREP standards include: 

• EBA-defined templates for capital, risk-weighted assets, leverage, and large exposures 
• Harmonized data definitions to eliminate ambiguity in reported figures 
• XBRL taxonomies that structure how supervisory data is tagged, validated, and submitted 
• Validation rules that enforce accuracy, completeness, and internal consistency 

These standards reduce interpretation differences between institutions and allow regulators to aggregate and compare data efficiently. COREP works alongside other supervisory frameworks, such as FINREP (Financial Reporting), which focuses on financial statements rather than capital and risk metrics. 

The primary purpose of COREP reporting is to provide a standardized framework for European banks and investment firms to report critical capital and risk data, including credit, market, and operational risk, as well as own funds. 

COREP reporting enables regulators to: 

• Monitor capital adequacy and ensure institutions meet minimum capital requirements 
• Assess risk exposure across credit, market, operational, and leverage risks 
• Identify systemic risks by comparing data across institutions and jurisdictions 
• Promote transparency and consistency in regulatory reporting 
• Strengthen stress testing and supervisory decision-making 

For financial institutions, COREP reporting is not only a compliance requirement but also promotes stronger data governance, risk management, and internal controls. 

Institutions subject to COREP are required to significantly increase the volume, granularity, and quality of regulatory data they report, often expanding from approximately 2,000 data elements to more than 10,000.

COREP also requires enhanced data robustness and validation to ensure reports can be generated accurately and on a timely basis. Institutions must continuously maintain and update their COREP reporting models as regulatory requirements evolve. 

Because the COREP reporting model is closely aligned with Basel III and continues to expand in scope, organizations must evaluate whether their existing reporting processes and systems can scale to meet ongoing regulatory demands.

CCH Tagetik COREP helps financial institutions prepare, validate, and deliver COREP reports through a pre-configured solution that supports accurate, compliant regulatory reporting and XBRL output. 

Here’s how: 

• Pre-built COREP reporting templates 
  Pre-configured COREP and FINREP templates, calculation rules, consolidation logic, and XBRL outputs eliminate the need to build reports from scratch. 
• Automated data integration and workflow 
  End-to-end automation supports data collection, mapping, validation, and submission, reducing manual effort and errors. 
• Data governance and quality controls 
  Built-in validation rules, diagnostic checks, and audit trails strengthen accuracy, transparency, and regulatory confidence. 
• Flexible configuration 
  Finance teams can tailor reporting structures to their chart of accounts and organizational needs using a no-code, finance-friendly interface. 
• Single trusted data source 
  Centralizing close, consolidation, and regulatory reporting data reduces inconsistencies and improves efficiency across COREP, FINREP, and other EBA supervisory reports.
