This document discusses implementing the Basel Committee on Banking Supervision's Principles for Effective Risk Data Aggregation and Risk Reporting (BCBS-239). It begins with some questions and challenges around BCBS-239 implementation related to the scope of risk data aggregation, level of automation, compliance focus, regulator engagement, implementation guidance, target state definition, and progress measurement. The document then presents six themes for interpreting the BCBS-239 principles: materiality, flexibility, reconciliation and validation, transparency, automation and adaptation, and speed and confidentiality. It outlines a framework moving from siloed, manual arrangements to a totally integrated, automated environment. Benchmarks are suggested to measure compliance levels against this target state.
