Model Risk
Model risk refers to the risk that arises from the potential inaccuracies or errors in financial models used to make decisions, such as pricing derivatives, managing risk, or conducting valuations. Models are based on assumptions and historical data, and if these inputs are incorrect or incomplete, the model may produce misleading results.
Example
A bank uses a model to price a complex derivative, but due to incorrect assumptions about volatility, the model produces an inaccurate valuation, resulting in a loss.
