What is the Capital Adequacy Ratio (CAR)?
The Capital Adequacy Ratio (CAR), also known as the Solvency Ratio, is a financial metric that assesses a bank’s capital strength. It determines the proportion of a bank’s total assets, including risk-weighted assets, that is held in the form of shareholders’ equity and other forms of capital. The CAR ensures that a bank can absorb a reasonable amount of loss and complies with statutory capital requirements, thereby maintaining its solvency and protecting depositors.
Key Components of CAR
- Tier 1 Capital: This is core capital, including equity capital and disclosed reserves.
- Tier 2 Capital: This covers subordinated debt, hybrid instruments, and other less secure forms of capital.
- Risk-Weighted Assets (RWAs): These are bank assets weighted by their risk exposure. Different asset classes are assigned different risk weights.
Importance of CAR
Maintaining an appropriate level of CAR helps banks:
- Absorb Shocks: Cushion potential financial losses.
- Protect Depositors: Ensure depositors’ funds are safeguarded.
- Build Confidence: Foster trust among stakeholders.
- Comply with Regulations: Adhere to international standards like Basel III.
Examples of How CAR is Used
Example 1: Assessing Bank Strength
A bank with total risk-weighted assets of $1 billion, a Tier 1 capital of $100 million, and a Tier 2 capital of $50 million will have a CAR as follows:
\[ \text{CAR} = \frac{\text{Tier 1 Capital} + \text{Tier 2 Capital}}{\text{Risk-Weighted Assets}} = \frac{100M + 50M}{1000M} = 15% \]
Example 2: Regulatory Compliance
Under Basel III, banks must maintain a minimum CAR of 8%, which will increase to between 10.5% and 13% to enhance financial stability.
Frequently Asked Questions (FAQs)
What is a good CAR?
A higher CAR indicates stronger solvency. Regulatory bodies set minimum levels, ranging from 8% to over 13%.
Why is CAR important for banks?
CAR helps banks absorb financial shocks, protects depositors, ensures compliance with regulatory requirements, and builds confidence in the banking system.
How is CAR calculated?
CAR is calculated using the formula: \[ \text{CAR} = \frac{\text{Tier 1 Capital} + \text{Tier 2 Capital}}{\text{Risk-Weighted Assets}} \]
What are Tier 1 and Tier 2 Capital?
- Tier 1 Capital: Core capital, including equity capital and reserves.
- Tier 2 Capital: Supplementary capital, including subordinated debt and hybrid instruments.
What’s the difference between CAR and leverage ratio?
CAR accounts for risk-weighted assets, whereas the leverage ratio measures capital in relation to total non-risk-weighted assets.
What happens if a bank’s CAR falls below the required minimum?
The bank may face regulatory action, be required to raise additional capital, or even face stiffer penalties/issues from regulatory bodies.
