Model risk management is an important aspect of financial institutions, as it helps to identify, assess, and mitigate the risks associated with using models in decision-making processes. One key aspect of model risk management is the concept of the "three lines of defence," which consists of three distinct layers of risk management designed to protect against model risk.
The first line of defence is the business unit, which is responsible for identifying, managing, and monitoring model risks within their specific area of operation. This includes the development and implementation of policies and procedures to ensure that models are used correctly and that any risks are identified and mitigated.
The second line of defence is the risk management function, which is responsible for providing oversight and independent assurance that the model risks are being effectively managed within the business unit. This includes conducting reviews and audits of models to ensure that they are fit for purpose and that any identified risks are being effectively managed.
The third line of defence is the internal audit function, which is responsible for providing independent assurance that the model risk management framework is effective and that the first and second lines of defence are operating effectively. This includes conducting regular reviews and audits to ensure that the model risk management framework is being followed and that any identified risks are being effectively managed.
