Abstract

This paper examines gold and cryptocurrencies' hedge and safe-haven capabilities against various downturns, including the COVID-19 pandemic and Geopolitical Risks (GPR), across different market conditions. The study covers a sample period from 2013 to 2021 at a daily frequency, employing the GARCH model and quantile regression with binary variables. The empirical results indicate that neither gold nor cryptocurrencies can act as strong hedges against infectious disease pandemics. However, gold, Bitcoin, and Ethereum exhibit weak safe-haven abilities during geopolitical risks. Using regression quantiles, the study finds that gold demonstrates a strong safe-haven against low and high Infectious Disease Epidemic Market Volatility (IDEMV) during extremely bearish and bullish markets. In contrast, Bitcoin and Ethereum act as strong safe havens only against low IDEMV during extreme bearish markets. Gold also shows a strong hedge propriety against extreme geopolitical events, while cryptocurrencies provide a weak hedge. Overall, gold exhibits strong safe-haven properties against low and high Geopolitical tensions, while cryptocurrencies' hedging and safe-haven abilities vary across markets. These findings convey insights for investors and guidance to supervisors on the evolution of gold, Bitcoin, and Ethereum as safe-haven and hedge instruments during both bearish and bullish markets.

摘要

本文考察了在不同市场条件下,黄金和加密货币针对包括新冠疫情和地缘政治风险(GPR)在内的各种衰退的避险和避风港能力。该研究涵盖了2013年至2021年的日频率样本期,采用了GARCH模型和带有二元变量的分位数回归。实证结果表明,黄金和加密货币都不能作为抵御传染病大流行的有力避险工具。然而,在面临地缘政治风险时,黄金、比特币和以太坊表现出较弱的避风港能力。通过回归分位数,该研究发现,在极度看跌和看涨市场中,黄金在应对低和高传染病流行市场波动(IDEMV)时表现出强大的避风港作用。相比之下,比特币和以太坊仅在极端看跌市场中对低IDEMV起到强大的避风港作用。黄金在应对极端地缘政治事件时也表现出强大的避险属性,而加密货币的避险属性较弱。总体而言,黄金在应对低和高地缘政治紧张局势时表现出强大的避风港属性,而加密货币的避险和避风港能力在不同市场中有所不同。这些发现为投资者提供了见解,并为监管机构在熊市和牛市期间将黄金、比特币和以太坊作为避风港和避险工具的演变方面提供了指导。
