Ways to Define Shocks in CDS Spread Systems

Summary

The document asks how to define a shock to a system driven by credit default swap spreads. It offers one possible measure: an increase in spreads, with a threshold chosen to mark when that increase qualifies as a shock.

It does not provide additional definitions, a calculation method, examples, or empirical evidence. The question leaves open whether shocks should be measured in absolute or relative terms, across one spread or several, or by changes over a specified time window. Any practical definition would therefore need further specification and validation against the system’s purpose.

Key ideas

• A CDS spread increase is proposed as one possible definition of a shock.
• A threshold is needed to distinguish an ordinary move from a shock.
• The document asks for other definitions but does not supply or assess them.

Assume we have a system that is built on the CDS spread values. If we want to shock the system, how can we define the shock? For instance, we can define it as the increase in the spread. Of course a threshold should be decided for this. What are other ways to define the shock?
