Financial Risk Modeling
Financial risk modeling is the use of formal mathematical and econometric techniques to measure, monitor, and control the market risk, credit risk, and operational risk on a firm's balance sheet, on a bank's trading book, or a fund manager's portfolio value. Risk modeling is one of many subtasks within the broader area of financial modeling.
Application
Risk modeling uses a variety of techniques, including market risk, value at risk (VaR), historical simulation (HS), or extreme value theory (EVT), in order to analyze a portfolio and make forecasts of the likely losses that would be incurred for a variety of risks. As above, such risks are typically grouped into credit risk, market risk, model risk, liquidity risk, and operational risk categories.
Many large financial intermediary firms use risk modeling to help portfolio managers assess the amount of capital reserves to maintain and to help guide their purchases and sales of various classes of financial assets.
Formal risk modeling is required under the Basel II proposal for all the major international banking institutions by the various national depository institution regulators. In the past, risk analysis was done qualitatively, but now, with the advent of powerful computing software, quantitative risk analysis can be done quickly and effortlessly.
