Correlation Breakdowns

Correlation breakdowns occur when the historical relationship between two assets suddenly changes, often during periods of extreme market stress. For example, assets that typically move in opposite directions might suddenly both plummet as investors rush to cash.

In derivatives and lending protocols, models that rely on stable correlations can fail, leading to inaccurate risk assessments and under-collateralization. When these breakdowns happen, the protective mechanisms designed for "normal" markets may be ineffective.

Systemic stability design must account for these potential deviations by stress-testing portfolios against extreme correlation scenarios, ensuring that protocols can survive even when traditional relationships dissolve.
