## Tail Risk Correlation Spikes

Tail risk correlation spikes occur when the likelihood of simultaneous extreme price movements across different assets increases significantly during market stress. These events are in the "tails" of the probability distribution, meaning they are rare but have a massive impact.

When correlations spike in the tails, it means that extreme negative events are more likely to occur across multiple assets at once. This makes tail risk management extremely difficult, as hedges may fail exactly when they are needed.

Quantitative models must account for these spikes to accurately estimate potential losses in extreme scenarios. It is a fundamental challenge in risk management.
