Introduction
Risk-Adjusted Return on Capital (RAROC) is a financial metric used to measure the performance of various units within a bank or financial organization. It was developed by Bankers’ Trust and the Bank of America in the 1980s to provide a standardized way to evaluate the risk and return of different business activities.
Historical Context
In the 1980s, financial institutions faced growing complexities in risk management due to increasing global market integration and innovative financial products. Bankers’ Trust and Bank of America pioneered the RAROC metric to better understand and manage these risks.
Methodology
RAROC is calculated by allocating capital at risk to a business unit and then dividing the return obtained from that unit by the allocated capital. The formula can be expressed as:
This process typically employs a Value-at-Risk (VaR) methodology to quantify the potential loss in value of a unit’s portfolio over a given period, for a specified confidence interval.
Types/Categories
- Managerial Units: Departments responsible for operational decisions.
- Product Units: Different financial products and services.
- Distribution Units: Sales and distribution channels.
- Treasury Units: Functions like trading desks and liquidity management.
Key Events
- 1980s: Development of RAROC by Bankers’ Trust and Bank of America.
- 1990s: Widespread adoption in major financial institutions.

Where:
- z-score = Confidence level (e.g., 1.65 for 95% confidence)
- \(\sigma\) = Standard deviation of returns
- \(\Delta t\) = Time period
