VaR Model Sensitivity Analysis

VaR Model Sensitivity Analysis is the process of examining how Value at Risk (VaR) calculations change in response to variations in input parameters or market conditions. VaR estimates the potential loss of a portfolio over a given time frame at a specific confidence level.

Sensitivity analysis helps users understand the robustness of this estimate by testing it against changes in volatility, asset correlations, or time horizons. This is vital for risk managers who need to know if their VaR estimates are reliable or if they are overly dependent on specific, potentially unstable assumptions.

By identifying which factors most heavily influence the risk estimate, teams can focus their monitoring efforts where they matter most. It is a key tool for improving the accuracy of risk reporting.
