中美贸易担忧缓和，基本金属再度走强

1. Report Industry Investment Rating - No specific industry investment rating is provided in the report. 2. Core Viewpoints of the Report - In the short - to - medium term, against the backdrop of tight scrap and ore supplies, there is a high risk of contraction in the smelting sector, and the supply - demand balance of base metals is expected to tighten, which supports base metal prices. However, weak demand limits the upside potential of prices. In the long term, there are still expectations of potential incremental stimulus policies in China, and supply disruptions in copper, aluminum, and tin remain, so the prices of copper, aluminum, and tin are expected to rise [3]. 3. Summary by Related Catalogs 3.1行情观点 3.1.1 Copper - Viewpoint: After the release of the communiqué of the Fourth Plenary Session of the 20th Central Committee, copper prices are showing a strong trend. - Logic: Macroeconomic sentiment has warmed up with the release of the communiqué and the resumption of Sino - US trade negotiations. On the supply - demand side, copper ore supply disruptions are increasing, and the cost and difficulty of scrap copper recycling have risen, leading to a decline in electrolytic copper production. Although the peak demand season has arrived, high prices have suppressed demand to some extent. - Outlook: Copper supply constraints remain, and considering the improved macro - sentiment, copper prices are expected to be oscillating with an upward bias [8]. 3.1.2 Alumina - Viewpoint: As the operating capacity of smelters declines, alumina prices are oscillating. - Logic: High - cost production capacity has reduced output, but the reduction is insufficient, and China still maintains a strong inventory build - up trend. Ore prices have shown a slight decline, so there is still pressure on the upside of the disk price. - Outlook: Alumina is expected to oscillate in the short term. It is recommended to wait and see or conduct short - term trading, and pay attention to the potential increase in volatility [10]. 3.1.3 Aluminum - Viewpoint: The risk of Mozal's shutdown has intensified, and aluminum prices have slightly rebounded. - Logic: The macro - tone at home and abroad is positive. On the supply side, some replacement capacities are being put into production, and the operating capacity and utilization rate are at a high level. On the demand side, orders in the peak season have improved marginally, and social inventories have started to decline. The current copper - aluminum price ratio is above 4.0, and the valuation of aluminum is relatively low. - Outlook: In the short term, aluminum prices are expected to be oscillating with an upward bias. In the medium term, the supply increase is limited, and demand remains resilient, so the center of aluminum prices is expected to rise [11]. 3.1.4 Aluminum Alloy - Viewpoint: With strong cost support, the disk is oscillating upward. - Logic: The tight supply of scrap aluminum is difficult to change in the short term, providing strong cost support. Although some enterprises have slightly reduced production due to unclear policies and weak demand, the overall reduction is not large. Demand has improved marginally, and social inventories and warehouse receipts have continued to rise. - Outlook: In the short term, prices are expected to oscillate within a range. In the medium term, due to unclear policy implementation and potential raw material disruptions, prices are expected to continue to oscillate [12]. 3.1.5 Zinc - Viewpoint: With optimistic macro - expectations and an open export window, pay attention to short - selling opportunities at high zinc prices. - Logic: Macroeconomic sentiment is optimistic. In the short term, zinc ore supply has become looser, and smelters' profitability is good, so their production willingness is strong. Domestic consumption is in the transition period between peak and off - peak seasons, and demand expectations are average. The overall fundamentals are in surplus, but the "soft squeeze" of LME zinc has not ended. - Outlook: In October, zinc ingot production will remain high, and demand recovery is limited, so inventories may continue to accumulate. Zinc prices are expected to oscillate [14]. 3.1.6 Lead - Viewpoint: Due to supply disruptions in recycled lead and low social inventories, lead prices have risen significantly. - Logic: On the spot side, the spot discount has narrowed slightly, and the price difference between primary and recycled lead has increased. On the supply side, the profitability of recycled lead smelters has improved, and production has increased slightly. On the demand side, the operating rate of lead - acid battery factories has recovered, and demand remains high. - Outlook: After the Fed's interest rate cut, the US dollar may still decline. After the holidays, lead supply growth has been slightly lower than expected, and demand is in the peak season. Lead prices are expected to be oscillating with an upward bias [15]. 3.1.7 Nickel - Viewpoint: With LME nickel inventories exceeding 250,000 tons, nickel prices are oscillating widely. - Logic: Market sentiment still dominates the disk. The industrial fundamentals are weakening marginally. Ore supply is relatively loose, and the reality of excess electrolytic nickel is serious, with significant inventory accumulation. - Outlook: In the short term, nickel prices are expected to oscillate widely [18]. 3.1.8 Stainless Steel - Viewpoint: With low warehouse receipts, the stainless - steel disk is rising. - Logic: Nickel - iron prices have weakened, and chromium prices are relatively stable. Stainless - steel production has increased in September, but the sustainability of demand in the "Golden September and Silver October" peak season needs to be monitored. Social inventories have decreased slightly, and warehouse receipts have continued to decline. - Outlook: Downstream demand is slightly lower than expected, and cost support has a certain boosting effect on steel prices. Stainless - steel prices are expected to oscillate within a range in the short term [22]. 3.1.9 Tin - Viewpoint: With supply constraints remaining, tin prices are oscillating. - Logic: There have been continuous supply disruptions in tin. Indonesia has taken measures to restrict supply, and the resumption of production in the Wa State's Manxiang mining area is slow. The domestic tin ore supply is tight, and the processing fee for tin concentrate remains low. - Outlook: With tight supply at the mine end, tin prices are expected to oscillate [23]. 3.2行情监测 - Comprehensive Index: The commodity index increased by 0.70% to 2250.50, the commodity 20 index increased by 0.58% to 2546.54, the industrial products index increased by 1.12% to 2229.03, and the PPI commodity index increased by 0.86% to 1342.15 [148]. - Plate Index: The non - ferrous metals index on October 23, 2025, increased by 0.70% on the day, 1.60% in the past 5 days, 3.15% in the past month, and 7.08% since the beginning of the year [149].
