Fundamentally speaking, government acquisition is a kind of market acquisition behavior, which increases market demand and will play a favorable role in commodity prices under the condition of certain output and inventory in the early stage.

The government's acquisition performance is obvious, and often the government will introduce a certain purchase price, which is also an important factor affecting the current commodity price changes.

To sum up, the purchase price and quantity will have a positive pull-up effect on the market. Coupled with the speculation of market funds, commodity prices will generally rise sharply after the market gets the news of purchase.
