Report Summary 1. Report Industry Investment Rating No information provided. 2. Core View of the Report The weakening US job market has heightened expectations of a Fed rate cut. However, due to the traditional domestic consumption off - season suppressing downstream demand, the total inventory of electrolytic copper at home and abroad is oscillating upwards. As a result, there is still room for the Shanghai copper price to decline. It is recommended that investors hold their previous short positions. They should pay attention to the support levels around 76,000 - 78,000 and the resistance levels around 80,000 - 81,000 for Shanghai copper, the support levels around 3,300 - 9,500 and the resistance levels around 10,000 - 10,200 for London copper, and the support levels around 4.0 - 4.2 and the resistance levels around 4.6 - 5.0 for US copper.

Industry News - Corporate News: Mitsubishi Materials Corporation is considering reducing the copper concentrate processing volume at its Onahama Smelting Co., Ltd. After the scheduled equipment maintenance from October to November this year, it plans to reduce copper concentrate processing through partial facility shutdowns while maintaining the processing of electronic waste, aiming to increase the utilization ratio of recycled materials and profitability. The 2025 cathode copper production forecast will be announced separately (Onahama's copper rough - smelting capacity is 230,000 tons) [2]. - Regional News: Peruvian informal miners have suspended negotiations with the government and may resume protests due to disagreements. The government refused to adjust the August 17 deadline and required miners to transfer explosives to a formal "powder magazine". About 20,000 miners who cannot meet the deadline will be excluded from the government's work regularization plan [2]. Supply - Demand Analysis - Supply Side: European high - quality scrap steel export restrictions, uncertainties in Sino - US tariff negotiations, negative price differences between domestic electrolytic copper and scrap copper, and the closure of the scrap copper import window may lead to a decrease in domestic scrap copper production (import) in August. Many copper smelters around the world are facing production adjustments, such as the shutdown of Glencore's PASIAR copper smelter in the Philippines, the suspension of Zhongkuang Resources' Isunebag plant in Namibia, and the suspension of Glencore's Altonorte smelter in Chile. Some projects are under construction or planned to increase production, like Jiangxi Hongyuan's second - phase project and the 200,000 - ton high - purity copper project in Baotou [3]. - Demand Side: The traditional domestic consumption off - season suppresses downstream demand [3]. Inventory Situation The inventory of electrolytic copper in domestic bonded areas has decreased compared to last week, while the domestic social inventory, LME inventory, and COMEX copper inventory have all increased [3]. Investment Strategy Investors are recommended to hold their previous short positions and pay attention to the support and resistance levels of Shanghai copper, London copper, and US copper as mentioned above [3].
