Using daily data for eight major cryptocurrencies and bivariate extreme value theory (peaks-over-threshold method), this study examines the extreme dependence between returns and trading volumes in the cryptocurrency market. It is shown that, irrespective of the cryptocurrency under...

Despite warnings issued by different financial institutions, cryptocurrencies are increasingly used for investment and speculation purposes. However, little is known about interdependencies within cryptocurrency markets. By employing an asymmetric Diagonal BEKK model, this paper examines...

Through the application of three pair-wise bivariate BEKK models, this paper examines the conditional volatility dynamics along with interlinkages and conditional correlations between three pairs of cryptocurrencies, namely Bitcoin, Ether and Litecoin. While cryptocurrency price volatility is...

Non-linearity is characterized by an asymmetric mean-reverting property, which has been found to be inherent in the short-term return dynamics of stocks. In this paper, we explore as to whether cryptocurrency returns, as represented by Bitcoin, exhibit similar asymmetric reverting patterns for...

In this paper, we analyse co-movements and correlations between Bitcoin and thirty-one of the most-tradable crypto assets using high-frequency data for the period from January 2019 to December 2020. We apply the Diagonal-BEKK model to data from the pre-COVID and COVID-19 periods, and identify...

This paper studies causal relationships and the potential of improving conditional quantile forecasting between Bitcoin and seven altcoin markets as well as between Bitcoin and three mainstream assets, namely gold, oil, and the S&P500, by applying the Granger-causality in distribution and in...

In this paper, we study the impact of Greek government-debt crisis events on European financial markets during the European sovereign debt crisis. We examine the effect of three categories of Greek government-debt crisis events in realized correlation and correlation jumps of government bonds,...

Through the application of Diagonal BEKK and Asymmetric Diagonal BEKK methodologies to intra-day data for eight cryptocurrencies, this paper investigates not only conditional volatility dynamics of major cryptocurrencies, but also their volatility co-movements. We first provide evidence that all...
