For example, the state purchasing and storage means that the state buys some goods in the spot market and keeps them by itself, so the corresponding goods circulating in the spot market will inevitably be less. Generally speaking, the futures market price will go up a little. It does not rule out that the market supply exceeds demand, and purchasing and storage will not have an impact on the market, so the price will not change much.
brief introduction
The so-called purchasing and storage mechanism generally refers to a market mechanism in which countries or collectives buy and store commodities when their prices fall and throw them out when their prices rise, so as to regulate the market and balance and stabilize the market prices.
Generally speaking, purchasing and storage refers to national purchasing and storage. As a strategic material reserve, it will be carried out in a lower price range, and its operability is not obvious. In the past, the national purchasing and storage department generally did not see the operation in the market, but only threw some out every few years.
