The financial industry evolves rapidly, offering numerous opportunities but also introducing inherent risks that require careful navigation by institutions. This paper explores the performance of traditional and digital assets as tools for hedging, diversification, and safe-haven strategies during the Russian-Ukrainian crisis and the Silicon Valley Bank (SVB) collapse. Utilizing daily data from April 30, 2021, to September 15, 2023, and employing the Asymmetric Dynamic Conditional Correlation (ADCC) model, which combines four Generalized Autoregressive Conditional Heteroskedasticity (GARCH) family models and two residual distributions, we conduct a comprehensive analysis. The results indicate that Bitcoin's role as a safe haven is limited during the geopolitical crisis, impacting specific stocks, while gold's effectiveness varies. Digix Gold (DGX) demonstrates robust safe-haven properties, and Paxos Gold (PAXG) proves notably effective for certain stocks. Before the SVB crisis, gold primarily acts as a diversifier but later emerges as a significant safe haven during the banking crisis. These findings provide valuable insights to portfolio managers, emphasizing the importance of adaptive asset allocation in addressing financial uncertainties.
金融行业发展迅速,带来了众多机遇,但也引入了内在风险,各机构需要谨慎应对。本文探讨了传统资产和数字资产在俄乌危机和硅谷银行(SVB)倒闭期间作为套期保值、多元化和避险策略工具的表现。利用2021年4月30日至2023年9月15日的日数据,并采用结合了四个广义自回归条件异方差(GARCH)族模型和两种残差分布的非对称动态条件相关(ADCC)模型,我们进行了全面分析。结果表明,在地缘政治危机期间,比特币作为避险资产的作用有限,对特定股票有影响,而黄金的有效性则有所不同。Digix Gold(DGX)表现出强大的避险属性,Paxos Gold(PAXG)对某些股票的避险效果尤为显著。在硅谷银行危机之前,黄金主要起到多元化作用,但在银行危机期间后来成为重要的避险资产。这些发现为投资组合经理提供了有价值的见解,强调了适应性资产配置在应对金融不确定性方面的重要性。
