This research aims to investigate the propagation of extreme downside risk, commonly referred to as tail risk, within commodity markets using an innovative CAViaR-based connectivity model. We also evaluate the influence of various crises, including the global financial crisis, the shale oil revolution, the COVID-19 pandemic, and the Russia-Ukraine conflict, on the dynamic relationships among seventeen different commodity markets. Our findings reveal a diverse pattern of interconnections among these markets during distinct crisis periods. Surprisingly, we observe that the nature of these interconnections is remarkably similar during geopolitical and health crises. Notably, the spillover effects between different commodity categories are more pronounced during the COVID-19 pandemic and the Russia-Ukraine conflict than during the global financial crisis and the shale oil revolution. However, it is important to note that the total risk spillovers are more substantial during the global financial crisis. Furthermore, our analysis delves into the unique characteristics of each market, revealing that precious metals can function as a safe haven for both energy and industrial metals during times of economic turbulence.

大宗商品市场的尾部风险溢出效应:危机时期的比较研究,大宗商品市场的尾部风险溢出效应:危机时期的比较研究

本研究旨在使用基于 CAViaR 的创新连接模型来调查商品市场中极端下行风险(通常称为尾部风险)的传播。我们还评估了各种危机(包括全球金融危机、页岩油革命、COVID-19 大流行和俄罗斯-乌克兰冲突)对 17 个不同大宗商品市场之间动态关系的影响。我们的研究结果揭示了在不同的危机时期这些市场之间存在不同的相互联系模式。令人惊讶的是,我们观察到,在地缘政治和健康危机期间,这些相互联系的性质非常相似。值得注意的是,不同大宗商品类别之间的溢出效应在新冠肺炎 (COVID-19) 大流行和俄罗斯-乌克兰冲突期间比全球金融危机和页岩油革命期间更为明显。但值得注意的是,全球金融危机期间总体风险溢出效应更为显着。此外,我们的分析深入研究了每个市场的独特特征,揭示了贵金属在经济动荡时期可以作为能源和工业金属的避风港。
