Understanding and opportunities in implementing the RDARR Guide

Risk data aggregation and reporting have been a central topic in banking supervision for years – and are currently receiving more attention from the ECB than ever before. With the Risk Data Aggregation and Risk Reporting (RDARR) Guide, supervisors are giving concrete shape to the requirements of the BCBS 239 principles, setting high standards for data management, data transparency and governance in credit institutions. In practice, implementation presents banks with significant challenges: diverging interpretations regarding scope of application, data lineage and end-user computing (EUC) are driving up complexity and effort. The Association of German Banks sets out in its position paper how a proportionate, risk-based and operationally sustainable implementation can be achieved – and calls for structured dialogue with supervisory authorities to ensure clarity, practicability and competitiveness.
