Basel III is a global regulatory framework designed to make banks more resilient by strengthening capital, leverage, and liquidity standards.
It was developed after the global financial crisis exposed serious weaknesses in the banking system.

Supporters respond that weaker banks impose much larger costs during crises, so stronger rules are worth it.
Basel III interacts with practical bank health indicators such as:
So the framework is regulatory, but the underlying bank balance sheet still determines whether the institution is actually healthy.
