In 2013 the Basel Committee on Banking Supervision published “The Principles for Effective Risk-Data Aggregation and Risk Reporting”. These principles, which became BCBS 239, were designed to remedy the risk data aggregation and risk reporting failings exposed during the financial crisis, and to deliver greater clarity and quicker information. The ambition of the Committee was to empower banks and financial institutions to facilitate better decision making. It took effect from January 2016, introducing a set of 14 best-practice principles spread across four closely related topics: overarching governance and infrastructure, risk data aggregation capabilities, risk reporting practices, and supervisory review, tools and cooperation.
