• CBA's Basel III CET1, Tier 1 and Total Capital ratios were 11.9%, 13.8% and 20.7% respectively

Commonwealth Bank of Australia (CBA) has released its March 2025 Basel III Pillar 3 report, providing detailed information on the Group's capital adequacy, risk-weighted assets, leverage, and liquidity. As at 31 March 2025, CBA's Basel III Common Equity Tier 1 (CET1), Tier 1 and Total Capital ratios were 11.9%, 13.8% and 20.7% respectively. The CET1 ratio increased 45 basis points during the quarter, primarily driven by capital generated from earnings. Total risk-weighted assets (RWA) increased by $2.1 billion to $484.5 billion, driven by increases in credit risk RWA and interest rate risk in the banking book (IRRBB) RWA, partly offset by lower traded market risk RWA. CBA's leverage ratio, defined as Tier 1 Capital as a percentage of total exposures, was 4.7% as at 31 March 2025, above the 3.5% minimum requirement for IRB banks. The Group's liquidity coverage ratio increased from 127% to 133% over the quarter, and the net stable funding ratio remained stable at 116%.

The Group has not provided any high-importance, price-sensitive forward-looking financial metrics in the announcement.
