Abstract

This paper investigates the correlations among Sino-US stock markets, economic policy uncertainty (EPU) and global oil market. Specificly, by adopting a TVP-SV-VAR model this study analyzes the dynamic effects of volatility of stock price in China and U.S. markets, EPU index, and volatility of oil price in OPCE from 2003 to 2020. It is found that the correlations among China and U.S. stock markets and the global oil market exist though time varying and in different ways.
Generally, effects in short- terms are stronger compared with medium-and-long terms. Most of the effects are positive which means that fluctuations strengths each other across the five markets, except
for the five variables across five markets show correlations to each other in both short terms and long terms. Compared with China stock market, the US stock market show stronger impacts on the global
oil market. The increasing economic policy uncertainty of the two countries both strengthen the fluctuation of global oil price, though the effect by China is weaker. Further, the impact of EPU on the
stock markets is strengthened during the global turbulent events such as the financial crisis and global COVID-2019 pandemic.
