National Context
What is the Common Equity Tier 1 Capital Ratio?
The CET1 ratio measures a bank's highest-quality capital (common equity, retained earnings, and qualifying disclosed reserves) against its risk-weighted assets. It is the most-watched single capital indicator in US bank supervision after the 2013 Basel III reforms.
Most well-managed US community banks report CET1 ratios between 11% and 16%. Ratios above 14% generally indicate comfortable capital cushions; below 10% triggers regulatory attention. The CET1 ratio should be read alongside the Tier 1 leverage ratio (which doesn't weight assets by risk), since a bank can have a high CET1 ratio while still being thinly capitalized on a leverage basis.
