MSCI: Modeling Future Shocks - Best Practices for Predictive Stress Tests

Posted: 1 November 2016  |  Source: MSCI


Stress testing has experienced a resurgence of interest in the aftermath of the 2008 global financial crisis. The lessons from that period, perhaps more than any previous one, taught the risk industry that expert judgment and economic insight may help investors anticipate and avoid exposure to major financial downturns by using forward-looking models.

But what are best practices for creating these forward-looking scenarios? Currently, there is no consensus.

As we see it, stress testing is the practice of evaluating risks whose likelihood can be better estimated by an expert, using economic reasoning and fresh information. Stress testing is the most direct way to insert human experience into risk models.

The subjective nature of stress testing involves a delicate balance between art and science. We portray MSCI best practices for stress testing in a flowchart that guides risk managers and other investors through a series of steps that lead to a structured way of stress testing portfolios:

The framework enables risk managers at financial institutions, asset owners, asset managers and hedge funds design stress tests for their own portfolios. MSCI uses this same methodology in designing stress tests for real-world scenarios, such as the possibility of an oil-price shock or the Federal Reserve raising interest rates.

Predictive stress testing offers a comprehensive and forward-looking way to evaluate the exposure of individual portfolios to potential risks. By combining expert knowledge with a structured protocol, this approach offers risk managers guidance in designing these scenarios, which are becoming a key element of modern risk management.
