BIS Basel Committee

The Basel Committee on Banking Supervision (BCBS) was established in 1974 by the central bank governors of the Group of Ten (G10) countries, following the failure of West Germany's Bankhaus Herstatt and the resulting disruption to international settlement systems. It is headquartered at and serviced by the Bank for International Settlements (BIS) in Basel, Switzerland, though it is legally distinct from the BIS itself.

The Committee has no formal supranational authority. Its standards, guidelines, and recommendations are not legally binding; members commit politically to implement them through their own national legal and regulatory frameworks. Despite this soft-law character, BCBS standards have become the de facto global benchmark for bank capital, liquidity, and supervisory practice.

Membership has expanded from the original G10 to 45 institutions from 28 jurisdictions, including central banks and bank supervisors from major emerging economies such as China, India, Brazil, and South Africa. The Committee reports to the Group of Central Bank Governors and Heads of Supervision (GHOS), its oversight body, which approves major decisions.

The BCBS is best known for the Basel Accords:

• Basel I (1988) introduced a minimum 8% capital-to-risk-weighted-assets ratio.
• Basel II (2004) added a three-pillar framework covering minimum capital, supervisory review, and market discipline.
• Basel III, issued in response to the 2007–2009 global financial crisis, tightened capital quality, introduced a leverage ratio, and added the Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR). Final Basel III reforms, sometimes called "Basel IV," were agreed in December 2017 with phased implementation.

Beyond the accords, the BCBS publishes the Core Principles for Effective Banking Supervision, guidance on operational risk, anti-money-laundering supervision, and climate-related financial risks. Its work is closely coordinated with the Financial Stability Board (FSB), the IMF, and the G20.
