What is model risk?
Financial institutions rely heavily on financial and economic models for a wide range of applications ― such as risk management, valuation, and financial / regulatory reporting. The level of sophistication of models used for such applications varies widely from relatively simple spreadsheet tools to complex statistical models applied to millions of transactions.
Regardless of the level of sophistication, model usage exposes a financial institution to model risk ― which typically involves the possibility of a financial loss, incorrect business decisions, misstatement of external financial disclosures, or damage to the company’s reputation arising from:
Possible errors in the model design and development process (including the design and development of changes to existing models) ― such as errors in the data, theory, statistical analysis, assumptions, or computer code underlying a model
Misapplication of models, or model results, by model users
Use of models whose performance does not meet company standards
Possible errors in the model production process ― such as errors in data inputs and assumptions, or errors in model execution.
