Definition of Tier 1 Common Capital Ratio
The Tier 1 Common Capital Ratio (CET1 Ratio) is a key measure of a bank’s core equity capital, which helps assess its financial strength in relation to its total risk-weighted assets. This ratio is critical for regulators and investors because it indicates how well a bank can weather financial storms, maintain solvency, and avoid turning into a financial Titanic.
“Banking is very good business if you don’t do any business.” — Alfred B. Sloan 😄
Formula
The formula to calculate the Tier 1 Common Capital Ratio is:
\[ \text{CET1 Ratio} = \frac{\text{Common Equity Tier 1 Capital}}{\text{Total Risk-Weighted Assets}} \times 100 \]
This formula gives a percentage of the capital that can absorb losses, leaving the banker grinning like a Cheshire cat! 🐱

Examples
-
Calculating the CET1 Ratio:
- If a bank has common equity of $200 million and risk-weighted assets of $1 billion, the CET1 Ratio would be: \[ \text{CET1 Ratio} = \frac{200,000,000}{1,000,000,000} \times 100 = 20% \]
-
Importance in Banking:
- A CET1 ratio of less than 4.5% is a red flag, rather like a banker riding a unicycle on a tightrope!
