In the global banking system, banks play a crucial role in managing money, providing loans, and supporting economic growth. However, banks also face risks such as borrowers failing to repay loans or sudden financial crises. To maintain stability and trust in the banking system worldwide, international banking regulations are necessary. These regulations ensure banks hold enough capital to absorb losses and continue operating safely.
One of the most important sets of global banking regulations is known as the Basel Norms. These norms were developed by the Basel Committee on Banking Supervision (BCBS), a group of central banks and regulators from major economies. The Basel Norms provide guidelines on how much capital banks must keep relative to their risks, helping prevent bank failures and financial crises.
The Basel Norms have evolved over time through three main phases: Basel I, Basel II, and Basel III. Each phase introduced improvements to address new challenges in banking risk management. Indian banks follow these norms under the supervision of the Reserve Bank of India (RBI) to ensure their safety and soundness.
The Basel Accords are international agreements that set standards for banking regulation, focusing mainly on capital adequacy, risk management, and liquidity. Here's a simple overview of each phase:

The Capital Adequacy Ratio (CAR) is a key measure used by banks and regulators to assess a bank's financial strength. It is the ratio of a bank's capital to its risk-weighted assets (RWA). This ratio shows how much capital a bank has to cover potential losses from its risky assets.
Capital is divided into two main categories:
| Capital Type | Description | Examples |
|---|---|---|
| Tier 1 Capital (Core Capital) | Capital that absorbs losses without the bank needing to stop operations. | Equity capital, disclosed reserves, retained earnings |
| Tier 2 Capital (Supplementary Capital) | Capital that absorbs losses in case Tier 1 is exhausted, but less secure. | Revaluation reserves, subordinated debt, hybrid instruments |
Maintaining a minimum CAR ensures that banks can absorb losses and protect depositors. The Basel Norms require banks to maintain a minimum CAR of 8%, though Indian regulations often require higher levels for safety.
Not all assets held by a bank carry the same level of risk. For example, loans to the government are generally safer than loans to private companies. To account for this, assets are assigned risk weights based on their riskiness. These weights are used to calculate the bank's risk-weighted assets (RWA).
The main types of risks considered under Basel Norms are:
Here is a simplified table showing typical risk weights for different asset classes:
| Asset Class | Risk Weight (%) | Explanation |
|---|---|---|
| Cash and Government Securities | 0% | Considered risk-free |
| Loans to Corporates | 100% | Standard risk |
| Residential Mortgages | 50% | Lower risk due to collateral |
| Past Due Loans | 150% | Higher risk due to default |
Step 1: Recall the formula for CAR:
\[ \text{CAR} = \frac{\text{Tier 1 Capital} + \text{Tier 2 Capital}}{\text{Risk Weighted Assets}} \times 100 \]
Step 2: Substitute the given values:
\[ \text{CAR} = \frac{500 + 200}{8000} \times 100 = \frac{700}{8000} \times 100 \]
Step 3: Calculate the ratio:
\[ \text{CAR} = 0.0875 \times 100 = 8.75\% \]
Answer: The bank's Capital Adequacy Ratio is 8.75%, which is above the minimum Basel requirement of 8%.
Step 1: Calculate risk-weighted assets (RWA) for Bank A:
Total RWA for Bank A = Rs.0 + Rs.3,000 + Rs.1,000 = Rs.4,000 crore
Step 2: Calculate CAR for Bank A:
\[ \text{CAR}_A = \frac{700}{4000} \times 100 = 17.5\% \]
Step 3: Calculate RWA for Bank B:
Total RWA for Bank B = Rs.0 + Rs.5,000 + Rs.1,000 = Rs.6,000 crore
Step 4: Calculate CAR for Bank B:
\[ \text{CAR}_B = \frac{700}{6000} \times 100 = 11.67\% \]
Answer: Bank A has a higher CAR (17.5%) compared to Bank B (11.67%), indicating Bank A is safer as it holds more capital relative to its risk-weighted assets.
Step 1: Recall the LCR formula:
\[ \text{LCR} = \frac{\text{High Quality Liquid Assets (HQLA)}}{\text{Total Net Cash Outflows over 30 days}} \times 100 \]
Step 2: Substitute the values:
\[ \text{LCR} = \frac{1200}{1000} \times 100 = 120\% \]
Answer: The bank's LCR is 120%, which means it has enough liquid assets to cover 120% of its expected cash outflows over 30 days. This is above the Basel III minimum requirement of 100%, indicating a strong liquidity position.
