Resumo
In this paper we investigate how tail codependency and systemic risk between the two major cryptocurrencies (Bitcoin and Ethereum) and two traditional assets (the S&P500 index and Gold) evolved before and after the Covid-19 pandemic. Using a quantile regression framework and a selected set of macroeconomic state variables we compute CoVaR and ?CoVaR measures. Our results suggest cryptocurrencies display increased shock transmission and systemic vulnerability in the post Covid-19 period.
