Basel Committee on Banking Supervision (BCBS)

The Basel Committee on Banking Supervision (BCBS) is the global standard-setter for the prudential regulation of banks. Hosted by the BIS, it writes the Basel framework on capital, liquidity and leverage that national regulators then put into law.

Also called: BCBS · Basel Committee · Basel standards · Basel III

The committee was set up by the central bank governors of the G10 at the end of 1974, after the failure of Bankhaus Herstatt showed how a bank collapse in one country could damage markets in others. Its members today are central banks and bank supervisors from 28 jurisdictions.

Its output is the Basel framework. Basel I (1988) set minimum capital against credit risk. Basel II refined how risk is measured. Basel III, written after the 2008 crisis, raised the quality and amount of capital and added a leverage ratio and two liquidity requirements. The committee also issues guidance on topics such as correspondent banking, operational resilience and banks' exposures to crypto-assets.

The committee has no legal authority of its own. Its standards bind a bank only when the bank's home jurisdiction adopts them. They still shape the market: how much capital a bank must hold against an activity largely decides whether it will offer that activity to payment firms and other clients.

In practice

Implementation dates and details differ between jurisdictions. A rule described as 'Basel III' may be in force in one country, delayed in another and modified in a third.
