Can cryptocurrencies hedge oil price fluctuations? A pandemic perspective

The article aims to verify whether cryptocurrencies can hedge extreme price movements in Brent crude oil. The COVID-19 pandemic revealed that oil prices are heavily influenced by economic uncertainty and the mobility factor. We analyse Brent crude oil prices from February 10, 2020, to February 10, 2022. We consider Bitcoin, BNB, Ether, Tether, and USD Coin, the top five cryptocurrencies by market capitalization, as possible hedges. We explore their potential to protect oil investments using two approaches. The first focuses on price movement, and the second one on minimizing portfolio volatility. We use three modelling techniques: asymmetric causality in prices, a threshold vector-autoregressive model for returns, and dynamic conditional correlation analysis. We show that while stablecoins provide the best protection against downward movements in oil prices, they do not reduce investment volatility. •We investigate hedging properties of cryptocurrencies against Brent oil fluctuations.•We focus on the dynamic dependency in returns.•We construct minimum risk hedging portfolios.•Stablecoins offer better protection against falling oil prices, but do not reduce portfolio volatility.
