Report Overview - Report Title: Copper Futures Daily Report [1] - Date: November 12, 2025 [2] - Researcher: Zhang Ping, Yu Feifei, Peng Jinglin [3] Industry Investment Rating - Not provided Core Viewpoints - Copper prices are expected to continue to fluctuate strongly. The reopening of the US government may release the frozen TGA account, and the expectation of liquidity release has pushed up overnight risk assets. Although the rise of copper prices has narrowed due to the weakening of A - shares, the expected decline of domestic social inventories and the possible end of the US government shutdown will support copper prices [10]. Summary by Directory 1. Market Review and Operation Suggestions - Copper prices fluctuated strongly. The expectation of liquidity release pushed up overnight risk assets, and the intraday high of Shanghai copper's main contract jumped to 87,050. However, as A - shares weakened, the increase of copper prices narrowed. The spot copper rose 230 to 86,765, and the spot premium remained flat. The strengthening of copper prices slowed down the release of downstream orders, but with the gradual decline of domestic social inventories, the spot premium is expected to have limited downward space. The loss of spot imports expanded to over 700, the LME 0 - 3 contango narrowed to 14.85, and the Shanghai - London ratio decreased. It is expected that domestic social inventories will continue to decline in the short term, supporting copper prices [10]. 2. Industry News - In October, the sales volume of lithium concentrate in Brazil decreased significantly month - on - month because the largest lithium spodumene producer, Sigma lithium, did not export during this period. In October, Brazilian producers exported 9,993 tons of spodumene concentrate, an 85% decrease from the unusually high 66,800 tons in September, but exports increased by about 54% year - on - year. Sigma Lithium plans to announce its 7 - 9 monthly performance after the stock market closes on November 14 [11]. - On November 10, the State Administration for Market Regulation announced that it approved the establishment of a joint venture between Codelco and SQM with additional restrictive conditions. The two companies planned to form a joint venture through asset injection to jointly operate the lithium mine project in the Atacama Salt Lake in Chile. The restrictive conditions require the two companies and the joint venture to make commitments such as continuing to fulfill contracts, supplying fairly and reasonably without discrimination, and reporting major supply changes in a timely manner, which is beneficial to the stable supply and reasonable price of lithium carbonate products [11][12]
