Definition of Common Equity Tier 1 (CET1)
Common Equity Tier 1 (CET1) is a crucial component of a bank’s Tier 1 capital, which primarily consists of common stock and retained earnings. Financial regulators use CET1 to evaluate a bank’s capital strength and ability to absorb losses during economic downturns. CET1 is pivotal in ensuring that a bank has enough liquid assets to meet obligations while maintaining a balance between risk and growth.
CET1 vs AT1: What’s the Difference?
| CET1 | AT1 |
|---|---|
| Composed of common stock and retained earnings | Composed of various instruments not considered common equity |
| Directly measures bank’s financial stability during crises | Provides additional capital cushion beyond CET1 |
| Used primarily in stress tests and regulatory assessments | Tends to be more hybrid in nature and can include perpetual bonds |
| Plays a critical role in maintaining capital adequacy ratio | Aids in maintaining Tier 1 ratios but can be converted to equity under stress |

Frequently Asked Questions
What is the minimum CET1 ratio required by regulators?
The minimum CET1 capital ratio varies by jurisdiction, but under Basel III requirements, it is generally set to at least 4.5% of risk-weighted assets.
How does CET1 influence a bank’s lending capacity?
A higher CET1 ratio indicates a stronger capital base, enabling banks to lend more aggressively while ensuring they have a safety net for economic downturns. More fuels for their financial engines!
Can a bank operate with less than the required CET1 ratio?
Technically, it can operate, but it walks a tightrope! Regulators may impose restrictions and require corrective actions—which definitely spoils the fun!
Why is CET1 primarily composed of common stock?
Common stock is considered the best form of capital as it absorbs losses directly, standing as a first line of defense against economic shocks. It’s like the superhero in the realm of bank capital!
