Description
In the context of various volatile changes in the international situation in recent years, such as the impact of public health emergencies, the intensification of regional conflicts, and trade frictions, studies regarding the complexity of crude oil price fluctuations focus on analyzing the special fluctuation characteristics of oil price in different historical ranges. Since the financial crisis in 2008, crude oil price have been in a new historical price range, and the factors that dominate energy price fluctuations have undergone earth-shaking changes along with economic and social development. The force of financial markets often plays a relatively active role, meaning researchers who study of the law of crude oil price fluctuations face a new-era task. The outbreak of the COVID-19 pandemic in late 2019 has profoundly affected people worldwide in terms of transportation and daily livelihood. Geopolitical conflicts such as the China–US trade friction, the Russia–Ukraine conflict, and the Iranian nuclear issue, have led to sudden changes in regional energy supply.
