Definition of Tier 1 Capital Ratio
The Tier 1 Capital Ratio represents the core capital of a bank, which is primarily comprised of common equity, retained earnings, and any regulatory adjustments. This ratio is calculated by dividing the bank’s Tier 1 capital by its total risk-weighted assets (RWAs). It is a crucial measure introduced under the Basel III regulatory framework designed to enhance the banking sector’s financial resilience.
Formula
\[ \text{Tier 1 Capital Ratio} = \frac{\text{Tier 1 Capital}}{\text{Total Risk-Weighted Assets}} \]
| Tier 1 Capital Ratio | Total Capital Ratio |
|---|---|
| Measures core capital | Measures total capital |
| Focuses on financial stability | Focuses on overall capital adequacy |
| Includes common equity and retained earnings | Includes Tier 1 and Tier 2 capital |
| Central to Basel III regulations | Comprehensive measure but less stringent |
Example
If a bank has Tier 1 capital of $200 million and total risk-weighted assets of $1 billion, the Tier 1 Capital Ratio would be calculated as:
\[ \text{Tier 1 Capital Ratio} = \frac{200,000,000}{1,000,000,000} = 0.2 \text{ or } 20% \]
This means that the bank maintains 20% of its risk-weighted assets in the form of core capital, a healthy cushion that can keep the bank afloat during turbulent times.
