Supply - Demand Analysis - Supply Side: Disruptions in the production of multiple domestic and foreign copper mines have led to a negative China copper concentrate import index, which has increased compared to last week. This has tightened the supply - demand expectation of domestic copper concentrates. The processing fees of domestic blister copper or anode plates are trending down, and the maintenance capacity of copper smelters from September to October has increased month - on - month [2]. - Demand Side: With the significant increase in copper prices, downstream buyers mainly make purchases based on rigid demand [2]. - Inventory Side: The social inventory of electrolytic copper in China has increased compared to last week; the inventory of electrolytic copper on the London Metal Exchange has decreased, and the inventory of COMEX copper has increased [2].
