Introduction to Capital Adequacy Ratio (CAR)

• Definition: The Capital Adequacy Ratio (CAR) is the ratio of a bank’s total capital to its risk-weighted assets (RWA), expressed as a percentage.
• Purpose: It measures a bank’s financial strength and ability to absorb potential losses.
• Alternative Name: Also referred to as the Capital to Risk-Weighted Asset Ratio (CRAR).
• RWA Concept: Risk-weighted assets represent assets with different levels of risk. For example:
  • Collateral-backed loans → Lower risk.
  • Unsecured loans → Higher risk.
• Implementation in India: The Reserve Bank of India (RBI) introduced the CRAR system for Indian banks in 1992.

Significance of Capital Adequacy Ratio

• Ensures financial stability: Maintains sufficient capital buffers to cover potential losses.
• Protects depositors: Enhances confidence in the banking system.
• Mitigates financial risks: Helps banks respond to credit risks and operational risks.
• Regulatory compliance: Ensures banks meet minimum capital requirements set by regulators.
• Prevents bank failures: A higher CAR indicates stronger financial health.

Formula for Calculating CAR

CAR is calculated using the formula:

• Tier 1 Capital: Core capital that absorbs losses while keeping the bank operational.
• Tier 2 Capital: Supplementary capital that absorbs losses during liquidation.

Tier 1 Capital – Core Capital

• Definition: The most reliable and stable form of capital.
• Purpose: Ensures banks can withstand financial losses without shutting down.
• Components:
  • Share Capital: Bank’s common equity.
  • Undistributed Profits: Retained earnings not distributed as dividends.
  • Preference Share Capital: Hybrid securities combining equity and debt characteristics.
• Form: Primarily in the form of equity capital.

Tier 2 Capital – Supplementary Capital

• Definition: Less stable capital that absorbs losses in case of bank failure.
• Purpose: Provides an additional financial cushion but offers less protection to depositors.
• Components:
  • Subordinated Debt: Long-term bonds issued by banks.
  • Revaluation Reserves: Gains from asset revaluation.
  • General Loan-Loss Reserves: Provisions set aside for non-performing loans.
  • Hybrid Capital Instruments: Debt-equity hybrid instruments.
• Form: Primarily in the form of debt capital.

Basel Committee and Global CAR Standards

• Formation: Established in 1974 after the collapse of Bankhaus Herstatt in West Germany.
• Objective: Set global banking regulations to ensure financial stability.
• Basel I (1988): Introduced minimum CAR requirement of 8%.
• Basel II (2004): Introduced risk-sensitive framework for better capital adequacy measurement.
• Basel III (2010): Strengthened capital requirements post the 2008 financial crisis.

Conclusion

• CAR is crucial for banking sector stability.
• Higher CAR reflects a bank’s financial strength and risk management capacity.

Regulatory bodies like RBI ensure strict CAR compliance to prevent financial crises.
