The main purpose of this study is to explore the commodity characteristics of crude oil market and gold market, and use CBP-GARCH model to capture whether there is instantaneous co-jump variation between the two markets when unexpected information occurs. The empirical results show that there is a phenomenon of volatility clustering between commodity markets. When the interest rate spread of stock market and long-term and short-term bonds expands, it has a significant impact on gold, but not in crude oil commodities, showing that there are different linkage between commodity market and financial market. In addition, when there is a transmission of market information, the jump intensity of crude oil will be higher than that of gold market, and there are instantaneous co-jump variation characteristics. This phenomenon can be attributed to the fact that the crude oil market is affected by market supply and demand, and the gold market plays a mixed characteristic of hedging and investment. Therefore, the empirical results of this study also suggest that investors should consider the asymmetric jump fluctuation variation between commodity markets when the market unexpected information is generated, so as to effectively control the risk degree in the portfolio.
