Delivery is the transfer of goods between the contract seller and the contract buyer. Because stock index futures are cash delivery, it will not involve spot delivery. The final settlement price is based on the arithmetic average price of the last two hours of the underlying index.

Crude oil is not convenient for delivery, and it is also tons, and it can only be used after treatment, which is not suitable for delivery. Unlike gold and silver, delivery is much more convenient.

Adjustment price for delivery: As international crude oil has a great influence on domestic refined oil prices, the delivery price of 93# gasoline is closer to the change of domestic refined oil prices, so the adjustment policy that the National Development and Reform Commission regularly adjusts refined oil prices every ten working days should be adopted. The adjusted price of this delivery reflects the expectation of the long-term trend of domestic refined oil prices, and is a tool to provide price reference for spot delivery of 93# gasoline.
