Common Equity Tier 1 Ratio

Definition

The Common Equity Tier 1 (CET1) Ratio is a key measure of a bank's financial strength, representing the ratio of a bank's core equity capital to its total risk-weighted assets. This ratio is crucial for assessing the capital adequacy of banks, ensuring they have enough high-quality capital to absorb losses and support ongoing operations. A strong CET1 ratio reflects a bank's ability to withstand financial stress, maintain solvency, and comply with regulatory requirements.
