In the banking sector, model risk management is the process of identifying, measuring, monitoring and controlling model risk. Model risk is the potential for losses arising from incorrect or imprecise models. Managing model risk is essential for effective decision-making and for maintaining the safety and soundness of banks.
Why is Model Risk Management Important?
Banks rely heavily on models for a variety of purposes, such as credit scoring, fraud detection, stress testing and asset/liability management. Models are also used extensively in trading and investment activities. With such heavy reliance on models, it is essential that banks have robust model risk management processes in place. Incorrect or imprecise models can lead to losses for the bank, which could impact its financial stability.
How to Manage Model Risk?
There are four main steps in managing model risk: identification, measurement, monitoring and control.
Identification: The first step is to identify all the models used by the bank and to assess their impact on the business. This includes understanding the purpose of the model, how it works and what risks it might pose to the bank.
Measurement: The next step is to measure the model risk. This includes estimating the potential financial impact of model errors and assessing the likelihood of those errors occurring.
Monitoring: Once the risks have been identified and measured, they need to be monitored on an ongoing basis. This includes tracking changes in model inputs and performance, as well as changes in market conditions that might impact the model’s accuracy.
Control: The final step is to put controls in place to manage model risk. This might include validating models before they are deployed, setting limits on exposure to model risk and establishing independent review processes.
