Stories and Lessons Learned

Scenario 1: A model risk analyst identified a potential bias in a credit risk model due to insufficient data on certain customer segments. This resulted in the timely adjustment of the model, reducing potential losses and enhancing the accuracy of credit decisions.

Lesson: Thorough data analysis is essential for identifying and mitigating model risks.

Scenario 2: A collaboration between a model risk analyst and a business unit identified the need for a new model to assess the risk of cyberattacks. The analyst worked with the business unit to define the model's scope and develop appropriate risk measures, resulting in a more robust assessment of cyber risk.

Lesson: Collaboration between analysts and business units leads to the development of innovative and effective models.

Scenario 3: A regular model monitoring process detected an unexpected increase in the volatility of a market risk model's outputs. The model risk analyst promptly investigated the issue, identified a flaw in a model parameter, and made the necessary adjustments to ensure continued model reliability.

Lesson: Regular model monitoring is crucial for identifying and addressing potential model issues.
