This research examines the behaviour of cryptocurrencies and stock markets during the COVID-19 pandemic through the wavelet coherence approach and Markov switching autoregressive model. Our results show a financial contagion in March, since both cryptocurrency and stock prices fell steeply....

Analyzing comovements and connectedness is critical for providing significant implications for crypto-portfolio risk management. However, most existing research focuses on the lower-order moment nexus (i.e. the return and volatility interactions). For the first time, this study investigates the...

We examine the relationship between cryptocurrencies (namely Bitcoin (BTC), Ethereum (ETH), and Ripple (XRP)) and COVID-19 cases/deaths. The Wavelet coherence analysis indicates that there is initially a negative relationship between Bitcoin and the number of reported cases and deaths; however,...

This paper assesses the impact of US policy responses to the Covid-19 pandemic on various cryptocurrencies and also technology stocks using fractional integration techniques. More precisely, it analyses the behaviour of the percentage returns in the case of nine major coins (Bitcoin - BITC,...

This study investigates herd effects in 101 cryptocurrencies during the period from January 2015 to June 2020. The results confirm the existence of herding behavior in the cryptocurrency market for the entire sample and show that herding asymmetry is present during both bullish and bearish...

Are gold-backed cryptocurrencies as stable as gold during crises? In this paper, we assess whether gold-backed stablecoins, purported to be safer than other cryptocurrencies indeed demonstrate safe haven characteristics during the COVID-19 pandemic. In the digital assets’ ecosystem,...

The notion that investors shift to gold during economic market crises remains unverifed for many cryptocurrency markets. This paper investigates the connectedness between the 10 most traded cryptocurrencies and gold as well as crude oil markets pre-COVID-19 and during COVID-19. Through the...

This paper assesses the impact of US policy responses to the Covid-19 pandemic on various technology-related assets such as cryptocurrencies, financial technology, and artificial intelligence stocks using fractional integration techniques. More precisely, it analyzes the behavior of the...

We apply wavelet method to daily data of COVID-19 world deaths and daily Bitcoin prices from 31th December 2019 to 29th April 2020. We find especially for the period post April 5 that levels of COVID-19 caused a rise in Bitcoin prices. We contribute both to the fast-growing body of work on the...
