Risk-adjusted return on capital (RAROC)

3 key takeaways

• RAROC measures the return on capital after adjusting for the risk taken, helping to compare the profitability of different investments or business activities on a risk-adjusted basis.
• It is used by financial institutions and businesses to allocate capital efficiently, ensuring that capital is deployed where it can achieve the highest risk-adjusted returns.
• RAROC is crucial for risk management, as it incorporates the cost of risk into performance evaluation, promoting better decision-making and resource allocation.

What is risk-adjusted return on capital (RAROC)?

Risk-adjusted return on capital (RAROC) is a financial performance metric that evaluates the profitability of an investment, project, or business unit by adjusting for the amount of risk taken.

This adjustment allows for a more accurate comparison of returns across different investments or activities with varying levels of risk. By incorporating risk into the return calculation, RAROC provides a clearer picture of the true economic value generated by an investment or business activity.

RAROC is particularly useful in financial institutions, such as banks and insurance companies, where it is used to assess the performance of different business units, allocate capital efficiently, and manage risks effectively.

How does RAROC work?

RAROC works by adjusting the return on capital to reflect the risk associated with an investment or business activity. The formula for calculating RAROC is:

RAROC = (Risk-Adjusted Return) / (Economic Capital)

where:

• Risk-Adjusted Return is the net income or profit generated by the investment or activity, adjusted for risk. This typically involves subtracting expected losses and the cost of capital from the gross return.
• Economic Capital is the amount of capital required to cover potential losses, determined based on the risk profile of the investment or activity.

Calculation steps

1. Calculate the gross return: Determine the gross return generated by the investment or activity.
2. Adjust for expected losses: Subtract expected losses associated with the investment or activity from the gross return.
3. Adjust for the cost of capital: Subtract the cost of capital, which includes the cost of equity and debt, from the adjusted return.
4. Determine economic capital: Calculate the amount of capital required to cover potential losses, based on the risk profile.
5. Calculate RAROC: Divide the risk-adjusted return by the economic capital.

Example calculation

Consider a bank evaluating a loan portfolio. The portfolio generates a gross return of $1 million. The expected losses from defaults are $200,000, and the cost of capital is $100,000. The economic capital required to cover potential losses is $500,000. The RAROC is calculated as follows:

1. Gross return: $1,000,000
2. Adjust for expected losses: $1,000,000 – $200,000 = $800,000
3. Adjust for cost of capital: $800,000 – $100,000 = $700,000
4. Economic capital: $500,000
5. RAROC: $700,000 / $500,000 = 1.4 or 140%

This RAROC of 140% indicates that the loan portfolio generates a risk-adjusted return of 140% of the economic capital required.

Importance of RAROC

RAROC is crucial for several reasons, particularly in promoting efficient capital allocation, improving risk management, and enhancing decision-making:

Efficient capital allocation

By providing a risk-adjusted measure of return, RAROC helps financial institutions and businesses allocate capital to the most profitable investments and activities. This ensures that capital is deployed where it can achieve the highest risk-adjusted returns, maximizing overall profitability.

Improved risk management

RAROC incorporates the cost of risk into performance evaluation, promoting better risk management practices. By adjusting returns for risk, organizations can identify and mitigate high-risk, low-return activities, enhancing their overall risk profile.

Enhanced decision-making

RAROC provides a comprehensive view of profitability by considering both returns and risks. This enables more informed decision-making, helping managers and investors choose investments and projects that offer the best risk-adjusted returns.

Benefits and limitations of RAROC

Understanding the benefits and limitations of RAROC provides insight into its practical applications and effectiveness.

Benefits

• Risk-adjusted performance measurement: RAROC offers a more accurate assessment of profitability by considering the risk associated with investments and activities.
• Capital efficiency: By focusing on risk-adjusted returns, RAROC promotes efficient capital allocation, ensuring resources are deployed where they can generate the highest value.
• Enhanced risk management: Incorporating the cost of risk into performance evaluation helps organizations identify and manage high-risk activities, improving their overall risk profile.

Limitations

• Complexity: Calculating RAROC can be complex, requiring detailed risk assessments and adjustments for expected losses and the cost of capital.
• Data requirements: Accurate RAROC calculations depend on reliable data on returns, expected losses, and economic capital, which may not always be readily available.
• Assumptions: The accuracy of RAROC depends on the assumptions used in calculating expected losses and economic capital, which can introduce potential biases.

Examples of RAROC in practice

To better understand RAROC, consider these practical examples that highlight its application in different contexts:

Example 1: Banking

A bank uses RAROC to evaluate the performance of different loan portfolios. By comparing the RAROC of each portfolio, the bank can allocate capital to the most profitable and least risky portfolios, optimizing its risk-adjusted returns and enhancing overall profitability.

Example 2: Insurance

An insurance company uses RAROC to assess the profitability of different insurance products. By adjusting returns for the risk of claims and potential losses, the company can identify high-performing products and allocate resources accordingly, ensuring efficient use of capital.

Example 3: Corporate finance

A corporation uses RAROC to evaluate investment projects. By considering both the potential returns and risks of each project, the company can prioritize investments that offer the best risk-adjusted returns, enhancing its overall financial performance.
