At present, domestic prices are still operating at high levels. However, the prices of gasoline and diesel, which are closely related to the people's consumption, have not been adjusted. This is not unrelated to the current pricing mechanism for refined oil products. Since 2011, the prices of international crude oil prices have been rising and falling frequently, and domestic refined oil prices have only undergone two adjustments. That is, on February 20 this year, the price of gasoline and diesel was increased by 350 yuan per ton. On April 7, gasoline and diesel were raised by 500 yuan and 400 yuan per ton respectively.
Since August, the prices of international crude oil prices have continued to decline, which has driven the rate of change in crude oil in the three regions from negative to positive, and the domestic refined oil market has ushered in a long-lost downward adjustment expectation. However, just as rumors rose intensified, the international crude oil ran up beautifully, while domestic product oil price adjustment faces a risk of abortion. With the arrival of the traditional sales season, September refined oil market conditions are expected to be better than in August. The rainy season in the south is basically over, and terminal demand will also be fully launched. Jin Jiuyin 10 is worth looking forward to. In early September, if the price adjustment still failed to materialize, the market doubted and the market became clear. Customers with continuous low inventory operations were expected to focus on replenishment. Under the psychological support of buying and not buying, the price might rise.
