Period: there are 1 adjustment windows every 10 working days.
Effective time: 24: 00 on the day of price adjustment release.
Rule: According to the price of crude oil in the international market, the state will adjust the price of refined oil.
Three stages of the development of China's refined oil supervision mechanism
The first stage: in 2008, China formulated a preliminary domestic refined oil adjustment mechanism, and the adjustment of domestic refined oil prices was adjusted according to the fluctuation of international oil prices. The National Development and Reform Commission (NDRC) adjusted the domestic refined oil prices according to the weighted average prices of refined oil in Singapore, new york and Rotterdam for 22 working days. When the oil prices in the three places change by more than 4% for 22 consecutive working days, the domestic refined oil price adjustment window will open and NDRC will release the latest oil prices.
In the second stage, in 20 13, the national development and reform commission shortened the price adjustment period to 10 day, which made the changes of domestic oil prices more closely related to international oil prices and made the price adjustment more frequent. At the same time, the 4% amplitude limit was cancelled. In order to save social costs, when the price adjustment of gasoline and diesel is lower than the 50 yuan per ton, no adjustment will be made, and it will be accumulated or offset in the next price adjustment.
In the third stage, 20 16, the international oil price continued to slump, and the China Development and Reform Commission issued a new price adjustment policy. When the international oil price is lower than 40 dollars per barrel, the domestic refined oil price will not be lowered!
