The Capital Adequacy Ratio (CAR), also known as the solvency ratio, measures a bank’s capital in relation to its risk-weighted assets and current liabilities. It ensures that financial institutions can absorb a reasonable amount of loss and complies with statutory capital requirements. The minimum international requirement for CAR is 8%, but this may rise to 10.5–13% under new regulatory proposals.
Historical Context
The concept of capital adequacy has evolved through various financial crises. Regulatory frameworks such as the Basel Accords have shaped how banks manage their capital:
- Basel I (1988): Introduced the basic CAR standard of 8%.
- Basel II (2004): Emphasized risk management and included operational risk in CAR calculations.
- Basel III (2010): Post-2008 financial crisis adjustments, increasing capital requirements and introducing additional buffers.
Types and Categories
CAR is divided into two key types based on the composition of capital:
- Tier 1 Capital: Core capital, including common equity tier 1 capital, such as common shares and retained earnings.
- Tier 2 Capital: Supplementary capital, including subordinated debt and hybrid financial instruments.
Key Events and Developments
- 1988: Introduction of the Basel I Accord.
- 2004: Basel II accord adoption.
- 2010: Implementation of Basel III reforms.
- Ongoing: Adjustments to capital requirements based on evolving economic conditions.
Detailed Explanations
Calculation of CAR
The CAR formula is:
Where:
- Tier 1 Capital includes common equity and disclosed reserves.
- Tier 2 Capital includes revaluation reserves, hybrid capital instruments, and subordinated term debt.
- Risk-Weighted Assets (RWA) are the total of all assets held by the bank, weighted by credit risk.

Importance and Applicability
The CAR is critical for:
- Bank Stability: Ensures banks have sufficient capital to absorb losses.
- Depositor Confidence: Protects depositor interests.
- Regulatory Compliance: Meets the statutory requirements set by financial authorities.
- Economic Stability: Reduces systemic risk in the financial system.
Examples
A bank with Tier 1 capital of $10 million, Tier 2 capital of $2 million, and RWAs of $100 million will have:
Considerations
- Economic Conditions: Economic downturns may necessitate higher CAR.
- Risk Profile: Banks with higher-risk profiles need stronger capital bases.
- Regulatory Changes: Continuous updates in regulatory frameworks affect required CAR levels.

Comparisons
- Capital Adequacy Ratio vs. Liquidity Ratio: CAR focuses on long-term stability, while the liquidity ratio focuses on short-term cash flows.
Interesting Facts
- Historical CAR Levels: Many banks in emerging markets historically maintained higher CARs due to perceived higher risks.

- Post-Crisis Resilience: Banks with robust CARs emerged stronger post-2008 financial crisis.
