The rate of change in crude oil has shifted from negative to positive, and the prices of refined oil products will see their eighth increase this year.

The price of gasoline and diesel will be increased at 24:00 on May 21st, with gasoline increasing by 75 yuan per ton and diesel by 70 yuan per ton, equivalent to 0.05 yuan for 89#, 0.06 yuan for 92#, 95#, and 0# per liter. The comprehensive change rate of crude oil in this round of price adjustment started negatively but eventually entered a positive range, corresponding to an increase in finished oil products. The highest change rate within the cycle was 1.61% on the tenth working day, and the lowest was -5.75% on the second working day. When the final adjustment window opened, the corresponding increases for gasoline and diesel were 75 and 70 yuan per ton, making it the eighth increase since 2026. Looking ahead, the US-Iran talks have entered the final stage, but the realization of a comprehensive ceasefire still faces significant uncertainty, as the US may resume military action against Iran. The market is showing a cautious and uncertain attitude, weighing the progress of the situation. Overall, it is expected that there is a high probability that the next round of finished oil price adjustments will be put on hold.
