During the current valuation cycle of domestic refined oil products, international crude oil prices rose first and then decreased. After the change rate of crude oil changed from negative to positive, the positive value showed a gradual downward trend. Zhuo Chuang said that as of the 9th working day of the domestic oil product pricing cycle, the reference crude oil change rate was 0.62%, corresponding to an increase of 35 yuan/ton of gasoline and diesel oil. Due to the small adjustment range, it is expected that at 24:00 on July 23, the oil product price adjustment will be stranded for the second time in the year.

Zang Wengang, an oil product analyst at Zhuochuang Information, said that at the beginning of the pricing cycle, the Gulf of Mexico storm cut U.S. offshore crude oil production and boosted international crude oil prices. But since then, after OPEC downgraded its forecast of crude oil demand and Mexico's storm weakened, international oil prices have changed from rising to falling, and gradually entered a turbulent downward path. Affected by this, the change rate of domestic crude oil changed from negative to positive, and then fell again. According to Zhuo Chuang's calculation, as of July 19, the 9th working day of the current cycle of domestic refined oil pricing, the reference crude oil change rate was 0.62%, corresponding to an increase of 35 yuan/ton of gasoline and diesel. However, as the impact of international crude oil factors on the change rate of refined oil is greatly weakened near the end of the price adjustment of refined oil, the grounding situation of the price adjustment of refined oil is basically solid and will usher in the second grounding in 2019.
