Abstract This paper studies asymmetric contagion effects between stock and cryptocurrency markets. We implement the time-varying symmetrized Joe-Clayton copula GARCH model and Bai-Perron breakpoint test to explore dynamic correlations between the daily log-returns of the two markets in each time range. The asymmetric contagion effects between the two markets are studied using the non-linear Granger causality test. We also find that the lower tail dependences are more significant than the upper ones. Our findings can be used as a reference for supervisory authorities, and also provide insights on risk hedging for rational investors to avoid underestimating risk when building their portfolios.
