What Basel III Capital Requirements requires
Basel III's framework, established by the Basel Committee on Banking Supervision's global regulatory framework and implemented through regulations such as the European Union's CRR and the US Federal Reserve's Regulation Q, mandates significantly strengthened capital and liquidity standards to enhance banking sector resilience. Institutions must maintain a minimum Common Equity Tier 1 ratio of at least 4.5 percent, a Tier 1 capital ratio of 6.0 percent or greater, and a Total Capital ratio equal to or exceeding 8.0 percent of risk-weighted assets. Beyond these minimums, a capital conservation buffer of at least 2.5 percent is required, alongside a calculated countercyclical capital buffer designed to protect against periods of excessive credit growth. Furthermore, a G-SIB surcharge is applied where applicable, consistent with the BCBS updated assessment methodology for higher loss absorbency by globally systemically important banks. A non-risk-weighted leverage ratio of 3.0 percent or more serves as a critical backstop. The framework also introduces two vital liquidity standards from dedicated BCBS publications: a Liquidity Coverage Ratio of at least 100 percent to ensure short-term survivability during stress, and a Net Stable Funding Ratio of 100 percent or greater to promote stable long-term funding structures. Compliance further necessitates meeting specific market risk capital requirements and applying the standardized approach for operational risk.
