Volatility Spillover Effects

Analysis

Volatility spillover effects, within cryptocurrency and derivatives markets, represent the transmission of volatility changes from one asset to another, often exceeding expectations based on linear correlation. This phenomenon is particularly pronounced in crypto due to interconnected trading strategies and information flow, where shocks in Bitcoin frequently propagate to altcoins. Quantifying these effects requires models beyond traditional GARCH, incorporating measures like dynamic conditional correlation and copula functions to capture tail dependencies. Effective risk management necessitates understanding these spillovers, as portfolio diversification benefits can be diminished during periods of heightened market stress.
