Recently, according to the National Development and Reform Commission, a new round of refined oil price adjustment window will open at 24:00 today (July 31). The details of this oil price adjustment are as follows: gasoline was raised by 685 yuan per ton, and diesel was raised by 655 yuan per ton. On a national average, the number 92 gasoline was raised by 0.54 yuan per litre; the number 95 gasoline was increased by 0.57 yuan per litre; and the number 0 diesel was increased by 0.56 yuan per litre. It is estimated that according to the 50L capacity of the general household automobile fuel tank, it will cost 27 yuan more to fill up a tank of No. 92 gasoline. Previously, on July 17, domestic oil prices had been raised (No. 92 gasoline was raised by 0.24 yuan per litre), and this oil price adjustment will form a "two consecutive rises" situation. In 2026, the retail price adjustment window of domestic refined oil products has opened 15 rounds of price adjustment windows, of which 10 rounds of upward adjustment windows, 4 rounds of downward adjustment windows, and 1 round of price adjustment window was stranded. There were 14 rounds of oil price changes, with No. 92 gasoline increasing by RMB 0.07/L, RMB 0.16/L, RMB 0.14/L, RMB 0.55/L, RMB 0.87/L, RMB 0.33/L, RMB 0.25/L, RMB 0.06/L, RMB 0.24/L and RMB 0.54/L, respectively, and decreasing by RMB 0.44/L, RMB 0.41/L, RMB 0.40/L and RMB 0.75/L. During the price adjustment cycle, the overall international oil price rose more or fell less, showing a periodical shock trend, and the average price of the current cycle was significantly higher than that of the previous round. One is the volatility of international oil prices. The price of Brent crude oil futures once exceeded $100/barrel; the oil price quickly fell back to around $84/barrel from July 24 to 28; and the oil price shock rose to near $89/barrel from July 29. Second, the blockage of important shipping routes for crude oil has exacerbated the shortage of supply. In the case of the Strait of Hormuz, the main export routes of crude oil from the Gulf States were blocked; in the case of the Red Sea and the Strait of Mande, ship traffic in the Strait of Mande was significantly reduced; and in the case of the Black Sea, the Sea of Azov and the Caspian Sea, crude oil exports from the region were disrupted. In addition, the storage reserves of US oil depots have fallen sharply, and oil consumption is at the peak of demand in the summer, which also disturbs the trend of international oil prices. According to the Price Monitoring Center of the National Development and Reform Commission, there is great uncertainty in the current geopolitical situation. In the future, we need to continue to focus on the impact of the international situation on international oil prices. (Compiled by Qin Chao, Automobile House).
