Report Industry Investment Rating - Not provided Core View - US employment market weakness boosts Fed's interest rate cut expectations, but the traditional domestic consumption off - season suppresses downstream demand, and the total inventory of domestic and foreign electrolytic copper fluctuates upward, suggesting that Shanghai copper prices may still have room to fall. It is recommended that investors hold their previous short positions cautiously and pay attention to support and resistance levels [2].

Industry News - **Policy Impact**: Due to the US government's decision on July 30, 2025, to exempt imported electrolytic copper from tariffs, the spread between COMEX copper and LME copper collapsed, leading a large amount of electrolytic copper to be transferred to the LME delivery warehouse in New Orleans [2]. - **Company Expansion**: Codelco planned to invest $5.7 billion in 2022 to expand El Teniente. As of March 31, 2025, the Andes Norte project was 73% complete, the Andesita project was 70% complete and started operation in February 2025, and the Diamante project was 43% complete. The expansion is expected to add 2 - 3 tons of copper production in 2025 and reach 15 tons after full - production, with the annual output expected to reach 50 tons after all projects are put into operation [2]. - **Accident**: A Chilean earthquake caused a casualty accident at Codelco's El Teniente copper mine, resulting in 6 deaths and halting nearby activities for investigation [2]. Investment Strategy - **Macroeconomic Situation**: The Fed kept the federal funds rate unchanged in January. Import tariffs pushed up commodity prices, causing an increase in the annual rates of US consumer - end inflation CPI and core CPI in June. Due to the possible significant downward revision or far - below - expected new non - farm payrolls in June - July, the US economy shows "stagflation" characteristics, increasing the expectation of Fed interest rate cuts in September, October, and December [2]. - **Supply and Demand**: In August, the domestic production (import) of copper concentrates increased month - on - month, the import index of Chinese copper concentrates was negative and higher than the previous week, and the port copper concentrate throughput (in - port, inventory) in the world (China) decreased (increased, decreased) compared with the previous week. The restriction on high - quality scrap steel exports in Europe and the uncertainty of Sino - US tariff negotiations affected scrap copper imports, and the import window for scrap copper was closed. Some copper smelters suspended production, and domestic smelters' rough - smelting maintenance capacity in August may decrease month - on - month, which may lead to an increase in domestic rough copper production (import) in August [2]. - **Trading Advice**: Hold previous short positions cautiously and pay attention to support and resistance levels of Shanghai copper, London copper, and COMEX copper [2]
