Correlation Convergence
Correlation convergence is a market phenomenon where the correlations between different assets rise toward one during periods of high market stress. In normal market conditions, different cryptocurrencies might show varying degrees of correlation based on their utility or network usage.
However, when a systemic shock occurs, market participants often sell all risk assets indiscriminately to raise liquidity. This leads to a breakdown in diversification benefits, as assets that were previously uncorrelated begin to move in lockstep.
For portfolio managers, correlation convergence is a critical risk, as it invalidates the protective strategies that were based on historical correlations. It means that during the times when protection is needed most, it is often the least effective.
Understanding this concept is essential for stress-testing portfolios and designing hedging strategies that account for tail risk. It serves as a reminder that diversification is not a permanent shield against market volatility.
Instead, it is a dynamic factor that must be continuously reassessed based on the prevailing market regime.
