The emergence of the covid-19 health crisis, in this advanced technological era where connections between markets, nations, and economies have grown stronger than ever before, the shock of the COVID-19 pandemic quickly had an impact on both physical and digital financial assets. The Chinese financial market experienced the first consequences of the covid-19 pandemic, then spilled over to other financial markets, including those for cryptocurrencies and the precious metals. This study examines the impact of the covid-19 pandemic on the volatilities of the dynamics of bitcoin and gold. Both assets share some characteristics, such as online trading platforms, however, gold is a tangible financial asset unlike bitcoin, which is digitally generated without any physical form. This study argues that the similarities and differences between bitcoin and gold play major roles in how the covid-19 crisis affected their respective dynamics. Using daily data ranging from 9/22/2014 to 1/31/2023 and employing ARMA as the mean equation for GARCH model, the impact of the health crisis (covid-19) is examined on the volatilities of the prices and volumes of bitcoin and gold. Empirical evidence points out that, the pandemic has a symmetric impact on the volatilities of bitcoin and gold price returns, causing them to be more volatile. The impact of the covid-19 observed on the volume returns of the assets, however, is asymmetrical. The empirical results give evidence to the role that the vital differences existing between these assets played during the covid-19 pandemic.
在这个先进的技术时代,市场、国家和经济之间的联系比以往任何时候都更加紧密,新冠疫情的爆发对实体经济和数字金融资产都产生了冲击。中国金融市场率先受到新冠疫情的影响,随后波及其他金融市场,包括加密货币市场和贵金属市场。本研究考察了新冠疫情对比特币和黄金动态波动性的影响。这两种资产具有一些共同特征,例如都可以在线交易,但黄金是一种有形的金融资产,而比特币是一种没有任何实物形式的数字货币。本研究认为,比特币和黄金之间的相似性和差异性在新冠疫情如何影响它们各自的动态方面发挥了重要作用。使用 2014 年 9 月 22 日至 2023 年 1 月 31 日的日数据,并采用 ARMA 作为 GARCH 模型的均值方程,本研究检验了新冠疫情对比特币和黄金价格和交易量波动性的影响。实证证据表明,疫情对称地影响了比特币和黄金价格回报的波动性,使它们变得更加波动。然而,新冠疫情对资产交易量回报的影响是不对称的。实证结果证明了这些资产之间存在的重要差异在新冠疫情期间所发挥的作用。
