A committee at Basel that writes the rule book for banks
Background
A forum of supervisors, the Basel Committee on Banking Supervision sets the global standards by which banks are regulated. It is hosted by the Bank for International Settlements in Basel, and works through what is called the Basel Process. Its 45 members are central banks and bank supervisors from 28 jurisdictions. It exchanges information on the banking sector and financial markets to spot risks to the global financial system. Guidelines and sound practices go with those standards. The full set of its standards is called the Basel Framework. Basel III sits inside that framework, and the Committee monitors how it is being put in place, so that internationally active banks face a level playing field. Its published data covers the Countercyclical capital buffer (CCyB) and Global systemically important banks (G-SIB).
