Stress Testing


Stress Testing – Confluence of the Actuaries and Economists Viewpoints in the New Economic Environment

Actuaries Summit 2017

An integral part of stress testing is understanding where vulnerabilities to macroeconomic shocks lie. This is however a challenging problem.
Key challenges include

  • Lack of data to calibrate models
  • Changes in the business and macro-economic environment which mean that the use of historic experience may not be valid.

In this presentation we look at different approaches to tackling this challenge. We take in the viewpoint of both actuaries and economists. The actuary is often tasked with translating a specific shock or adverse scenario of the world into forecasts of financial metrics. Economists can provide an important perspective on how scenarios can work itself through the segments of the economy, and the potential responses of different economic agents.

The current environment is continuing to evolve. We are in an unprecedented low interest environment. The speed of information flow is rapid amongst both other institutions as well as consumers. Further capital and liquidity flows are global and can turn on or off very rapidly. The impact of new and agile disruptors who may be service provider or competitors also needs to be considered.

This is a continuously evolving area where close cooperation between experts with different viewpoints and backgrounds can provide greater insights, and help understand the impact from macro-economic scenarios.
