19.3 Risk Adjusted Return on Capital (RAROC)

Risk Adjusted Return on Capital (RAROC) is a key tool in strategic cost management. It helps financial institutions measure performance while accounting for risk, guiding decisions on capital allocation and pricing strategies.

RAROC compares risk-adjusted returns to economic capital, providing a more accurate picture of value creation than traditional metrics. By incorporating expected and unexpected losses, it enables better resource allocation and risk-based pricing across different business units.

1 of 3

• Economic capital represents the amount of capital a financial institution needs to remain solvent
• Calculated based on the institution's risk profile and desired confidence level
• Expected loss refers to the average anticipated loss over a specific time period
• Determined using historical data, statistical models, and expert judgment
• Financial institutions typically set aside reserves to cover expected losses (loan loss reserves)

Exploring Unexpected Loss and its Implications

• Unexpected loss represents potential losses beyond the expected loss
• Calculated using statistical methods, often at a high confidence level (99.9%)
• Covers extreme events or "tail risks" that could threaten the institution's solvency
• Economic capital primarily addresses unexpected losses
• Unexpected losses require additional capital beyond reserves for expected losses

RAROC Applications

Implementing Risk-Adjusted Performance Measurement

• RAROC allows for comparing performance across different business units or products
• Adjusts returns for the level of risk taken, providing a more accurate measure of value creation
• Helps identify which activities are truly profitable when accounting for risk
• Enables management to make informed decisions about resource allocation and strategy
• Can be used to set performance targets and design incentive compensation systems

Optimizing Capital Allocation and Risk-Based Pricing

• RAROC guides efficient capital allocation across various business lines or investments
• Directs capital to activities with the highest risk-adjusted returns
• Supports risk-based pricing strategies for products and services
• Allows institutions to price loans, insurance policies, or other financial products based on their risk profile
• Helps ensure that riskier activities are priced appropriately to compensate for potential losses

RAROC Calculation and Analysis

Understanding the RAROC Formula and Its Components

• RAROC formula: $RAROC = \frac{[Risk-Adjusted Return](https://www.fiveableKeyTerm:risk-adjusted_return)}{Economic Capital}$
• Risk-Adjusted Return calculated by subtracting expected loss from revenues
• Economic Capital represents the amount of capital required to cover unexpected losses
• RAROC expressed as a percentage, similar to other return metrics
• Higher RAROC indicates better risk-adjusted performance

Comparing RAROC with ROE and Interpreting Results

• ROE (Return on Equity) does not account for risk, while RAROC does
• RAROC provides a more comprehensive view of performance in relation to risk
• Allows for fair comparison between activities with different risk profiles
• RAROC can be compared to a hurdle rate to determine if an activity is creating value
• Activities with RAROC above the hurdle rate are considered value-creating
• RAROC analysis helps identify activities that may appear profitable but destroy value when risk is considered
