Basel III is the international regulatory framework developed by the Basel Committee on Banking Supervision (BCBS) post-global financial crisis to enhance bank prudential standards. It focuses on improving the quantity and quality of capital, constraining leverage, and bolstering liquidity resilience. The framework employs a multi-metric "belts and suspenders" approach combining risk-weighted assets (RWA) with non-risk-based measures.

- **Pillar 2Supervisory review via ICAAP and stress testing.
- **Pillar 3Standardized disclosures for RWA comparability. No formal certification; relies on national supervisory compliance.
