Model Validation - Not Just for Quants

In an article recently published in the ERisk Monthly Newsletter, it is stated that model validation is not a purely quantitative endeavor. Below is a quote from the article.

Model validation is often thought of as a rather technical and mathematical exercise. However, bank losses from model risk are often caused by poor governance of the wider modeling process, or by a poor understanding of the assumptions and limitations surrounding the model results, rather than by errors in equations.

The growing importance of models in helping executives answer some of banking’s most critical questions – from compliance and capital adequacy to business performance and risk-adjusted compensation – suggests that model validation is too important to be narrowly defined or left to the “quants”.

For both best practice and regulatory compliance reasons, senior bank executives must begin to take a more commanding role in ensuring that model validation is aligned with the overall interests of the bank – and that the bank’s investment in sound risk modeling can be easily communicated and proved to third parties.
