Abstract

This paper uses a novel econometric framework to dissect connectedness into spillovers and correlations. The results based on a sample of the largest cryptocurrencies show that spillovers play a small role relative to correlations. This finding implies that the crypto market is highly efficient as information is processed quickly and minimal lagged giving and receiving of information occurs. Tether stands out for its relatively high auto-spillovers emphasizing its special role as a stablecoin. We also find increased correlations during the COVID-19 outbreak consistent with financial contagion but no significant increase in spillovers. Graphical Abstract
