1. The relationship between supply and demand directly affects the market pricing of commodities. When the relationship between supply and demand is in a temporary balance, the market price of the commodity will fluctuate within a narrow range, and when the relationship between supply and demand is unbalanced, the price will fluctuate greatly. In the futures market, an indicator reflecting the change of copper supply and demand is inventory.

2. Inventory is one of the important factors affecting copper price. Under different market conditions, enterprises will take different measures to increase or decrease inventory. In order to ensure the production of raw materials or accelerate the flow of funds, we will also use the throughput reserves in different periods to stabilize the copper market.

3. Influence of other policies and regulations As the copper market is an international market with a large volume of international trade, increasing the changes in import and export policies and exchange rate systems of relevant countries and cracking down on smuggling will also have an impact on copper prices.
