弱美元继续发酵，沪铜再度带动基本金属突破上行

Report Industry Investment Rating No specific industry investment rating was provided in the report. Core Viewpoints - In the short - and medium - term, the influence of the weak US dollar and supply concerns dominates again. The reality of weak consumption and relatively loose supply - demand has become a secondary factor. Shanghai copper drives the base metals to break through and rise. Opportunities for going long on copper, aluminum, and tin can be continuously monitored. In the long - term, there are still expectations of potential incremental stimulus policies in China, and there are still supply disruptions for copper, aluminum, and tin. There are expectations of tightening supply - demand, so the price trends of copper, aluminum, and tin are optimistic [1]. - The weakening of the US dollar index causes copper prices to run strongly; the cost support for alumina is weak and prices remain under pressure; aluminum prices fluctuate at high levels due to inventory accumulation; the aluminum alloy market should focus on demand changes and the price fluctuates at high levels; zinc prices fluctuate at high levels with differentiated inventory trends at home and abroad; the rebound space of lead prices is limited due to the decline in the operating rate of lead - acid battery enterprises; nickel prices continue to rise due to the expected policy disturbances in Indonesia; the stainless - steel market is driven up by the rebound of nickel prices; high prices suppress downstream demand, and tin prices fluctuate at high levels [2]. Summary by Related Catalogs 1. Copper - Information Analysis: The 2026 copper concentrate long - term processing fee benchmark is 0 dollars/ton and 0 cents/pound. CSPT members will reduce copper ore production capacity by over 10% in 2026. In November 2025, SMM China's electrolytic copper production increased month - on - month and year - on - year. On December 23, the 1 electrolytic copper spot was at a discount to the contract. As of December 22, copper inventory increased. LME plans to set and implement position limits for key and related contracts from July 6, 2026 [6][7]. - Main Logic: The loose liquidity supports copper prices. The supply of copper mines is increasingly disrupted, and the expectation of refined copper supply contraction is strengthened. The terminal demand is weak, and inventory accumulates, limiting the upward space for copper prices. The risk of LME copper cornering has temporarily weakened [8]. - Outlook: Copper prices are expected to fluctuate strongly [8]. 2. Alumina - Information Analysis: On December 23, the spot price of alumina decreased. The alumina warehouse receipt decreased by 6,641 tons [8][9]. - Main Logic: The high - cost production capacity has fluctuations, but the supply contraction is insufficient, and the inventory is strongly increasing. The raw material prices are weak, and the cost support is general. The warehouse receipt is in the process of destocking, but there is pressure on the price [9][10]. - Outlook: Alumina is expected to fluctuate [10]. 3. Aluminum - Information Analysis: On December 23, the average price of SMM AOO aluminum decreased. As of December 22, aluminum ingot and aluminum rod inventories changed. On December 23, the SHFE electrolytic aluminum warehouse receipt increased. In November 2025, China's unforged aluminum and aluminum products exports changed. Some enterprises launched the "aluminum replacing copper" standard implementation, and South32 raised the aluminum ingot premium [11]. - Main Logic: The macro - expectation is positive. The domestic supply is high, and the overseas supply may tighten in the long - term. The high aluminum price suppresses demand, and the inventory accumulates [12]. - Outlook: In the short - term, aluminum prices are expected to fluctuate strongly. In the medium - term, the price center may rise [12]. 4. Aluminum Alloy - Information Analysis: On December 23, the price of Baotai ADC12 remained unchanged, and the spread with AOO aluminum changed. The SHFE registered warehouse receipt remained unchanged. An Indonesian electrolytic aluminum project started production, and in October, China's scrap aluminum imports increased [13]. - Main Logic: The cost support is solid. The operating rate is flat, and there is a risk of production reduction. The end - of - year automobile demand may weaken, and the warehouse receipt inventory is high [13]. - Outlook: In the short - and medium - term, prices are expected to fluctuate strongly [13]. 5. Zinc - Information Analysis: On December 23, the spot premium of zinc in different regions was different. As of December 23, the SMM seven - region zinc ingot inventory increased. In November 2025, China's zinc concentrate imports increased [15]. - Main Logic: The macro - outlook is positive. The short - term supply of zinc ore is tight, and the production of zinc ingots has decreased. The domestic consumption is in the off - season, and the demand is average. In the short - term, zinc prices may continue to fluctuate at high levels. In the long - term, zinc prices may decline [16]. - Outlook: Zinc prices are expected to fluctuate [16]. 6. Lead - Information Analysis: On December 23, the price of waste electric vehicle batteries and SMM1 lead ingots increased. As of December 22, the lead ingot social inventory decreased, and the SHFE lead warehouse receipt decreased. Since December, the implementation of the new national standard for electric bicycles has affected battery consumption, and the operating rate of some enterprises has declined [17]. - Main Logic: The spot premium decreased slightly, and the warehouse receipt decreased. The supply decreased due to maintenance, and the demand was mixed, with the operating rate of lead - acid battery enterprises slightly weakening [17]. - Outlook: Lead prices are expected to fluctuate [18]. 7. Nickel - Information Analysis: On December 23, LME nickel inventory increased, and SHFE nickel warehouse receipt decreased. The price of high - nickel pig iron increased. Indonesia plans to revise the nickel ore pricing formula and reduce the 2026 nickel ore production target [20][21]. - Main Logic: The domestic nickel supply decreased in November, but the overall supply pressure still exists. The demand is in the off - season. If Indonesia's production reduction plan is implemented, the supply - demand surplus will decrease [22]. - Outlook: Before the policy is implemented, nickel prices may remain strong [22]. 8. Stainless Steel - Information Analysis: The stainless steel futures warehouse receipt decreased. On December 23, the spot premium in Foshan was 45 yuan/ton. The price of high - nickel pig iron increased, and Indonesia plans to reduce the 2026 nickel ore production target [23]. - Main Logic: The cost of stainless steel is supported, and the production is expected to decline in December. The inventory may accumulate, and the warehouse receipt is at a low level [24][25]. - Outlook: Before the Indonesian policy is implemented, stainless - steel prices may remain strong [25]. 9. Tin - Information Analysis: On December 23, the LME and SHFE tin warehouse receipts decreased, and the SHFE tin position decreased.
