China's energy stock market jumps: To what extent does the COVID-19 pandemic play a part?

COVID-19 and China commodity price jump behavior: An information spillover and wavelet coherency analysis

“…Firstly, the lockdown in China's “Zero-COVID” policy will significantly impact the energy market, especially the crude oil market. The significant reduction in the transport of China's goods and people has led directly to a decline in energy consumption ( Narayan, 2020 ; Selmi et al, 2022 ), energy supply ( Akhtaruzzaman et al, 2021 ), and China's energy firms ( Tong et al, 2022 ). Especially, crude oil is the blood of the industry, and fluctuations in crude oil prices are easily transmitted to other commodity prices ( Kang et al, 2017 ; Umar et al, 2021a , Umar et al, 2021b ).…”

“…In the general case, the pattern of movement of commodity prices obeys a Geometric Brownian Motion (GBM), i.e. , the price of a commodity consists of a drift term reflecting changes in the mean, and a fluctuation term reflecting changes in the variance ( Tong et al, 2022 ). However, some studies have found that the movement pattern of commodity prices is likely to add a jump term to the GBM.…”

How Energy Sector Reacted to COVID‐19 Pandemic? Empirical Evidence from an Emerging Market Economy

“…Crude oil is sometimes considered an economy's blood, and as a reason, oil price variations have a significant impact on many countries throughout the world [24]. For instance, Tong et al [27] claimed that jumps in the oil market were the most strongly connected to the disease, notably through the peak and refall stages. e COVID-19 pandemic has put the energy markets under stress, but its most direct impact was on energy consumers through isolation measures that have deepened preexisting energy poverty problems, increased residential demand due to increased occupancy, and reduced the earnings of many families that have been economically affected by the crisis [60].…”

“…First, to the best of our knowledge, the study provides the first empirical evidence for the case of Romania. Prior studies were focused on a diverse worldwide sample [4,26], several European countries [17], China [9,13,21,[27][28][29][30][31][32], G7 nations [33], Indonesia [19], South Korea [20], United States [32,[34][35][36], Germany and United States [10], Canada [18], United Kingdom [37], United States and China [38], United States and Japan [39], China and Nigeria [40], Turkey [41], various countries with the leading energy sectors by market capitalization [5], emerging economies [2], or advanced and developing nations [42]. Hence, the evidence for emerging market economies is limited.…”

A multiscale integrated analysis of the COVID-19 restrictions: The energy metabolism of UK and the related socio-economic changes

“…The main contributions of the paper can be listed as follow: First, a metabolic approach is used, for the first time, to investigate the energy implications of the COVID-19 restrictions. Compared to existing studies, that have mainly been focused on the analyses of specific energy markets, energy compartments and sectoral energy use ( Tong et al, 2022 ; Su et al, 2022 ; Cihan, 2022 ), the MuSIASEM technique provides the possibility to integrate a wide range socio-economic and energy data at different scales of analysis (such as the sectoral and the national scale). Within this context, the MuSIASEM approach is particularly suitable to provide a comprehensive analysis of the trends taking place inside the system, as well as the role that external variables (such as crisis and resource constraints) can have on energy allocation and use ( Lu et al, 2016 ; Han et al, 2018 ).…”
