Basel accords

The Basel accords are not treaties but internationally agreed standards issued by the Basel Committee on Banking Supervision, hosted at the Bank for International Settlements in Basel. Basel I focused on minimum capital for credit risk; Basel II refined risk sensitivity and supervisory review; Basel III strengthened capital quality, leverage and liquidity after the financial crisis. Switzerland implements Basel standards through its banking regulation and supervisory practice, often with additional requirements for systemically important banks. The accords shape comparability and resilience, while national law determines legal force.
