The Financial Sector Assessment Program (FSAP) carried out a targeted evaluation of issues relating to the effectiveness of banking supervision and regulation in Japan. The scope of the work focused on the key findings from the 2017 Basel Core Principles (BCP) Detailed Assessment Report (DAR) and the transformation of the supervisory approach by the Financial Services Agency (FSA) undertaken since the last FSAP. The overall conclusion of the 2017 DAR was that the supervisory framework was generally sound, but some key priority areas were identified as needing to be addressed. This note reviews progress made in these areas as well as examining the fundamental shift to a more risk-focused, principles-based supervisory approach than before.
