Models which typically rely upon historical data to operate successfully are no longer fit for purpose and, in their scramble to find a way forward, many banks put in place quick fix solutions that created more issues than they solved.
Banks now need to put in place a much more coherent model risk management strategy, taking a two-stage approach. In the short term, they need to address the immediate issues, using a crisis response plan. In the longer term, they must create a model risk management framework which is both more resilient and more flexible to enable it to adapt more effectively to rapidly changing risks.
