This study compares the dynamic spillover effects of gold and Bitcoin prices on the oil and stock market during the COVID-19 pandemic via time-varying parameter vector autoregression. Both time-varying and time-point results indicate that gold is a safe haven for oil and stock markets during the COVID-19 pandemic. However, unlike gold, Bitcoin's response is the opposite, rejecting the safe haven property. Further analysis shows that the safe-haven effects of gold on the stock market become stronger when the pandemic critically spreads.
本研究通过时变参数向量自回归方法,比较了新冠疫情期间黄金和比特币价格对石油市场和股票市场的动态溢出效应。时变和时间点结果均表明,在新冠疫情期间,黄金是石油市场和股票市场的避险资产。然而,与黄金不同的是,比特币的反应则相反,不具备避险资产属性。进一步分析表明,当疫情严重蔓延时,黄金对股票市场的避险效应会增强。
