Model risk

Back in April, the Prudential Regulation Authority (PRA) published its Supervisory Statement (SS 3/18), setting out its expectations as to the model risk management practices that firms should adopt when using stress test models.

The PRA’s model risk management principles for stress testing are centred on four key principles:

  • Firms should have an established definition of a model and maintain a model inventory.
  • Firms should have an effective governance framework, policies, procedures and controls to manage their model risk
  • Firms should have a robust model development and implementation process and ensure appropriate use of models
  • Firms should undertake appropriate model validation and independent review activities to ensure sound model performance and greater understanding of model uncertainties.

In the following articles we explore what each of the principles mean and more importantly what the pitfalls are and how you can make sure you don’t fall foul of the regulator.
