Model validation interest rate risk models

When making decisions under uncertainty we typically want to know how well our model of the world has performed in the past, and if it would help us to make better decisions in the future. We therefore want to review how our models have performed in reality and to what extend they can really help us in the decision making process. In other words, we want to perform a model validation on various interest rate risk models.

We start with a some interest rate risk models from the financial sector. As their primary focus is the determination of capital needs for possible losses caused by extreme changes, they are of particular interest. Consider for example the following models:

  • Basel focusses on the banking sector in virtually all western countries
  • Solvency II focusses on the insurance sector in Europe
  • Wtp focusses on the pension fund industry in the Netherlands

These models are often used as a reference model in risk reports. This raises the question: How well do these models perform? and Is it possible to do better?

In this series of articles we will perform a model validation or backtest on these interest rate risk models and compare the model performance with our Base and Regime models:
