The Bank Regulation and Supervision Survey is a unique source of comparable economy-level data on how banks are regulated and supervised around the world. In the early 2000s, the World Bank created a global database of bank regulation and supervision. The second update of the database was issued in 2003, the third in 2007, and the fourth in 2012. The most recent survey was started in 2017 and completed in 2019. The dataset gathers information from bank regulatory agencies around the world on regulations and supervisory practices pertaining to bank (1) entry/licensing, (2) ownership, (3) capital, (4) activities, (5) external auditing, (6) internal management or governance, (7) liquidity and diversification, (8) depositor protection, (9) provisioning, (10) disclosure and information, (11) dealing with problem institutions and exit from the industry, (12) supervisory powers, (13) banking sector characteristics, (14) consumer protection, and (15) Islamic banking. Overall, the surveys cover more than 180 countries, although the number varies from one survey to the next and approximately 80 countries have participated in all four waves.
