BCBS (Basel Committee on Banking Supervision)

The Basel Committee on Banking Supervision (BCBS) is an international body of central banks and bank supervisors that develops standards for the regulation, supervision, and risk management of internationally active banks. It was established in 1974 by the central bank governors of the Group of Ten countries, in the aftermath of the failure of West Germany's Herstatt Bank, which exposed serious gaps in cross-border supervision and settlement risk.

The Committee has no formal supranational authority. Its standards are not legally binding; instead, members commit to implementing them through their own domestic legal and regulatory frameworks. Despite this soft-law character, BCBS standards have become de facto global benchmarks, partly because the IMF and World Bank assess compliance through the Financial Sector Assessment Program (FSAP).

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 three pillars: minimum capital requirements, supervisory review, and market discipline through disclosure.
• Basel III, developed 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). Finalisation reforms agreed in December 2017 (often called "Basel IV" by industry) are being phased in over several years.

The Committee is hosted by, but legally distinct from, the Bank for International Settlements (BIS). Membership has expanded beyond the G10 to include major emerging economies such as China, India, Brazil, and South Africa, and currently spans central banks and supervisors from roughly 28 jurisdictions. Decisions are taken by consensus. The Committee reports to the Group of Governors and Heads of Supervision (GHOS), its oversight body, which endorses major standards before publication.
