Basel I
Basel I was the 1988 international bank-capital accord that introduced a common definition of capital, broad credit-risk weights, and an 8% total capital standard.
Basel I, Basel II, Basel III, and the supervisory rules that define bank capital, risk-based requirements, buffers, leverage, and disclosure.
The Basel accords are international bank-supervision standards developed by the Basel Committee on Banking Supervision. They provide a common framework for capital, risk measurement, supervisory review, and disclosure, but national authorities must implement them through enforceable local rules.
| Framework | Main contribution |
|---|---|
| Basel I | Established a common risk-based capital framework beginning in 1988 |
| Basel II | Organized minimum capital, supervisory review, and market discipline into three pillars |
| Basel III | Strengthened capital quality and added buffers, leverage, liquidity, and revised risk constraints |
Basel III builds on rather than erases the three-pillar structure. Historical references should be interpreted using the rule and reporting date that applied at the time.
