Key Takeaways
- Essential for Stability: CET1 is crucial for assessing the robustness of banks in scenarios of financial distress.
- Regulatory Benchmark: Acts as a primary gauge for regulatory frameworks like Basel III to ensure banks can endure financial upheavals.
- Capital Composition: Comprised mainly of common shares and retained earnings, reflecting the purest form of a bank’s capital.
Understanding Common Equity Tier 1 (CET1)
Initiated under the Basel III regulations, CET1 represents the core measure of a bank’s financial strength from a regulator’s perspective. Its primary components are common shares and retained earnings, excluding any forms of convertible or hybrid instruments. CET1 serves as the gold standard for risk-absorbent capital; it’s the financial buffer that remains when the smoke clears and the mirrors have been put away.
Composition and Importance
CET1 includes:
- Common Shares: The bedrock of bank capital, representing ownership and voting rights in a company.
- Retained Earnings: Historically, the part of earnings a bank has deemed too precious to distribute as dividends, opting instead for reinvestment and rainy-day buffering.
These elements are pivotal as they remain available to absorb losses, continuing operations during financial storms without the need to seek external help or worse, a government bailout—banking’s version of calling up mom and dad when things get tough.
Regulatory Spotlight
Under Basel III, the CET1 ratio—a bank’s CET1 capital to its risk-weighted assets (RWA)—must be at least 4.5%. This ratio ensures that the banks maintain a buffer of high-quality capital that can absorb losses during periods of stress before creditors and depositors are affected. Think of it as the financial equivalent of the airbags in your car.
Special Considerations
Loss Absorption
When financial turbulence hits, CET1 is the first line of defense—it takes the hit so others don’t have to. This preemptive sacrifice preserves the integrity of the banking system, somewhat akin to the ancient ritual of burying treasures to appease the gods and protect the village.
Regulatory Constraints
If CET1 levels fall below the regulatory minimum due to losses, banks may face operational restrictions such as freezing dividend payments—effectively grounding them like unruly teenagers until their financial health improves.

- Tier 2 Capital: Often referred to as supplementary capital, this includes subordinated debt and revaluation reserves.
- Additional Tier 1 Capital (AT1): Comprises non-convertible instruments that do not meet CET1 criteria but still serve as loss-absorbing capital.
- Risk-Weighted Assets (RWA): Bank assets categorized by risk levels to determine capital requirements.

Like a financial knight in shining armor, CET1 stands ready to protect against the dragons of economic downturns.
