As a strategic reserve material, crude oil is more likely to be bought in the futures market for the following reasons:

1, the purchase in the international market will be more restricted by oil countries. Buying in the futures market is relatively simple.

2. As a reserve, it is not needed now, and the purchase from the futures market takes up less funds and reduces the transportation and warehousing links. The month near the delivery can also be changed, and it is necessary to decide whether to realize it according to the actual situation. Commercial reserves not only need to consider the actual commercial risks, but also need huge funds.

There are no restrictions.
