Understanding the tier 1 common capital ratio
The tier 1 common capital ratio serves as a pivotal metric in the financial landscape, providing a nuanced insight into a bank’s resilience and overall financial strength. This ratio measures a bank’s core equity capital against its total risk-weighted assets, excluding preferred shares and non-controlling interests. This article delves deep into the components, calculation, and significance of the tier 1 common capital ratio.
Key components and calculation
The formula for the tier 1 common capital ratio is:
Breaking down the elements:
- T1CCR: Tier 1 Common Capital Ratio
- T1C: Tier 1 Capital
- PS: Preferred Stock
- NI: Noncontrolling Interests
- TRWA: Total Risk-Weighted Assets
This formula emphasizes the exclusion of preferred shares and non-controlling interests, distinguishing it from the closely-related tier 1 capital ratio.
Interpreting the tier 1 common capital ratio
Risk-weighted assets play a pivotal role in calculating the ratio, with different assets systematically weighted for credit risk. Cash and government securities carry minimal risk, while loans bear higher weights based on their credit risk. Regulators employ the tier 1 common capital ratio to categorize a firm’s capital adequacy, ranging from well-capitalized to critically undercapitalized.
A well-capitalized firm must maintain a tier 1 common capital ratio of 7% or higher, refraining from actions that would diminish this ratio. For systemically important financial institutions (SIFIs), additional requirements are imposed, with a 10% threshold for well-capitalization. Non-well-capitalized firms face restrictions on dividends and share buybacks.
