What Is the Difference between Historical and Hypothetical Stress Testing?

Historical stress testing uses data from actual past market events (e.g. 2008 crisis) to assess portfolio losses.

Hypothetical stress testing uses fabricated, extreme but plausible scenarios (e.g. a sudden geopolitical shock) that may not have occurred historically. Both are used to ensure margin coverage in severe conditions.
