Systemic Correlation Breakdown

Systemic correlation breakdown refers to the phenomenon where assets that usually exhibit low or negative correlation suddenly move in perfect lockstep during a market crash. Under normal conditions, investors diversify to mitigate risk, assuming these assets will behave independently.

However, during a liquidity crisis, the demand for cash or the need to meet margin requirements forces participants to sell all liquid assets simultaneously. This convergence destroys the diversification benefit exactly when it is needed most.

In the crypto domain, this is often observed when risk-off sentiment hits both high-cap tokens and derivative-backed assets at the same time. Recognizing this breakdown is vital for accurate portfolio stress testing.
