Capital Adequacy Rules

1. Meaning and Concept

Capital Adequacy Rules (CAR) are banking regulations that require banks to maintain a minimum level of capital in relation to their risk-weighted assets (RWA).

In simple terms:

Banks must keep enough “own money” (capital) to absorb losses and protect depositors.

Capital acts as a financial safety cushion against:

• loan defaults
• market risks
• operational losses
• systemic financial shocks

2. Legal and Regulatory Framework

(A) International Framework

• Basel Committee on Banking Supervision (BCBS)
  • Basel I (1988)
  • Basel II (2004)
  • Basel III (2010–ongoing reforms)

(B) India

• Reserve Bank of India (RBI) Guidelines
• Based on Basel III norms
• Governed under:
  • Banking Regulation Act, 1949
  • RBI Master Circulars on Capital Adequacy

3. Key Components of Capital Adequacy

1. Tier 1 Capital (Core Capital)

• Equity share capital
• Reserves
• Retained earnings
• Highest quality capital

2. Tier 2 Capital (Supplementary Capital)

• Subordinated debt
• Hybrid instruments
• Revaluation reserves

3. Risk-Weighted Assets (RWA)

Assets are weighted based on risk level:

• Government bonds → low risk
• Corporate loans → medium/high risk
• Unsecured loans → high risk

4. Capital Adequacy Ratio (CAR)

CAR=Tier 1 Capital + Tier 2 CapitalRisk Weighted Assets×100\text{CAR} = \frac{\text{Tier 1 Capital + Tier 2 Capital}}{\text{Risk Weighted Assets}} \times 100CAR=Risk Weighted AssetsTier 1 Capital + Tier 2 Capital​×100

Minimum Requirement (Basel III / RBI):

• Generally 9% in India (plus buffers)
