有色金属大宗金属周报：关税落地，铜价承压-20250713

Investment Rating - The investment rating for the non-ferrous metals industry is "Positive" (maintained) [4][106]. Core Views - The report highlights that copper prices are under pressure due to the implementation of a 50% tariff on copper by the U.S., which is expected to take effect in late July or early August. This has led to a significant increase in U.S. copper prices while London and Shanghai copper prices have declined [5][9]. - The report anticipates that global copper inventory transfers will conclude, providing some support for copper prices despite the short-term pressure from tariffs. It is expected that Shanghai copper will fluctuate between 77,000 and 79,000 CNY per ton in the near term [5]. - The aluminum market is characterized by low inventory levels, with aluminum prices experiencing high volatility. The report notes a slight increase in alumina prices and a decrease in aluminum production margins [5][26]. - Lithium prices are rebounding from the bottom, driven by a "reverse involution" trend, with expectations for supply-side reductions and seasonal demand support [5][78]. - Cobalt prices may rebound due to an extended export ban from the Democratic Republic of Congo, which is expected to tighten supply in the fourth quarter [5][88].
