The COVID-19 pandemic provided the first widespread bear market conditions since the inception of cryptocurrencies. We test the widely mooted safe haven properties of Bitcoin, Ethereum and Tether from the perspective of international equity index investors. Bitcoin and Ethereum are not a safe haven for the majority of international equity markets examined, with their inclusion adding to portfolio downside risk. Only investors in the Chinese CSI 300 index realized modest downside risk benefits (contingent on very limited allocations to Bitcoin or Ethereum). As Tether successfully maintained its peg to the US dollar during the COVID-19 turmoil, it acted as a safe haven investment for all of the international indices examined. We caveat the latter findings with a warning that Tether's dollar peg has not always been maintained, with evidence of impaired downside risk hedging properties earlier in our sample.
新冠疫情大流行带来了自加密货币诞生以来首次广泛的熊市状况。我们从国际股票指数投资者的角度,测试了比特币、以太坊和泰达币广受热议的避险属性。比特币和以太坊对多数所考察的国际股票市场而言并非避险资产,将它们纳入投资组合会增加下行风险。只有中国沪深300指数的投资者实现了适度的下行风险收益(这取决于对比特币或以太坊的极低配置)。由于泰达币在新冠疫情动荡期间成功维持了与美元的挂钩,它对所有所考察的国际指数而言都起到了避险投资的作用。我们对后一发现给出提醒,即泰达币并非总能维持与美元的挂钩,在我们样本期较早阶段有证据显示其下行风险对冲属性受损。
