1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The Fed's expectation of interest rate cuts has been fluctuating, and base metals may shift to a period of consolidation. In the short - to - medium term, concerns about supply disruptions continue to support prices. The positive tone of the Central Economic Work Conference is expected to improve demand, which will boost base metals. However, high prices may suppress consumption, and the fluctuating expectation of Fed rate cuts may restrict further price increases. 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 supply - demand situation is expected to tighten, and the prices of copper, aluminum, and tin are favored [1]. 3. Summary by Relevant Catalogs 3.1 Copper - **View**: Inventory is continuously accumulating, and copper prices are oscillating at a high level. The medium - term outlook is oscillating with an upward bias [6][7]. - **Information Analysis**: The Fed cut the federal funds rate target range by 25 basis points in December. The CSPT decided to reduce the capacity load of mine - copper production by over 10% in 2026. In November, China's electrolytic copper production increased both month - on - month and year - on - year. On December 15, the spot price of 1 electrolytic copper showed a premium, and the national copper inventory increased [6][7]. - **Main Logic**: The Fed's interest rate cut and balance - sheet expansion support copper prices. Supply disruptions in copper mines are increasing, and the CSPT's decision strengthens the expectation of supply contraction. Although the demand is in the off - season, the spot premium indicates that downstream acceptance of copper prices is rising. The increase in the premium of Chilean refined copper reflects the expectation of supply - demand tightness next year [7]. 3.2 Alumina - **View**: The oversupply situation has not improved significantly, and alumina prices continue to be under pressure. The medium - term outlook is oscillating [8]. - **Information Analysis**: On December 15, the spot prices of alumina in different regions showed different trends, and the alumina warehouse receipts decreased [8]. - **Main Logic**: Macroeconomic sentiment amplifies price fluctuations. High - cost production capacity has some fluctuations, but the supply contraction is insufficient. The domestic market is in a strong inventory - building trend, and raw material prices are weak. The current price difference between futures and spot is large, and the low futures price may drag down the spot price. However, as the valuation is in a low range, price fluctuations may increase [8]. 3.3 Aluminum - **View**: Inventory has started to accumulate, and aluminum prices are oscillating at a high level. The medium - term outlook is oscillating with an upward bias [11][12]. - **Information Analysis**: On December 15, the average price of SMM AOO aluminum decreased, and the inventory of aluminum ingots and aluminum rods increased. In November 2025, China's exports of unwrought aluminum and aluminum products decreased year - on - year but increased month - on - month. Some Indonesian aluminum plants are in the trial - operation or production stage [11]. - **Main Logic**: The macro - economic outlook is positive. The domestic production capacity and operating rate are high, while overseas power shortages may tighten future supply. High aluminum prices have suppressed demand, and the inventory has started to accumulate. Overall, the short - term macro - expectation and fundamentals support aluminum prices to oscillate with an upward bias, and the price center may rise in the medium term [12]. 3.4 Aluminum Alloy - **View**: Pay attention to demand changes, and the market is oscillating at a high level. The medium - term outlook is oscillating with an upward bias [13]. - **Information Analysis**: On December 15, the price of ADC12 remained unchanged, and the price difference between ADC12 and AOO aluminum changed. The registered warehouse receipts increased. In October, the import of scrap aluminum in China increased year - on - year, with Thailand being the main source [13]. - **Main Logic**: The supply of scrap aluminum is tight, providing strong cost support. The weekly operating rate has decreased, and there are still risks of production cuts in the medium term. The year - end seasonal peak of automobile sales is approaching the end, and demand may weaken. Although the social inventory has decreased slightly, the warehouse receipt inventory has increased. Overall, the price is expected to oscillate with an upward bias in the short and medium terms [13]. 3.5 Zinc - **View**: The export window has significantly narrowed, and zinc prices are oscillating at a high level. The medium - term outlook is oscillating [14][16][17]. - **Information Analysis**: On December 15, the spot premiums of zinc in different regions varied. The SMM seven - region zinc ingot inventory decreased. In September 2025, Peru's zinc concentrate exports decreased month - on - month but increased year - to - date [16]. - **Main Logic**: The macro - economic outlook is positive. The short - term supply of zinc ore is tight, and the processing fee has declined, leading to a decrease in zinc ingot production. The opening of the export window has relieved the domestic supply pressure. However, the domestic demand is in the off - season, and the overall demand expectation is average. In the short term, zinc prices may continue to oscillate at a high level, and there is a downward risk in the long term [16][17]. 3.6 Lead - **View**: The LME lead inventory has increased significantly, and lead prices are oscillating. The medium - term outlook is oscillating [18][19]. - **Information Analysis**: On December 15, the price of waste electric vehicle batteries decreased, and the price of lead ingots decreased. The domestic lead ingot social inventory increased, and the Shanghai lead warehouse receipts decreased. The recycling price of waste lead - acid batteries in some regions is stable, and the market activity has slightly improved [18]. - **Main Logic**: The spot premium and the price difference between primary and recycled lead are stable, and the futures warehouse receipts are decreasing. The price of waste batteries has decreased, and the smelting profit of recycled lead has slightly expanded. The production of lead ingots has decreased due to many smelter overhauls. The demand for lead - acid batteries is at a high level, but the increase in LME lead inventory will suppress the upside of lead prices [18][19]. 3.7 Nickel - **View**: The LME nickel inventory remains at a high level, and nickel prices are weak. The medium - term outlook is oscillating [19][21][22]. - **Information Analysis**: On December 15, the LME nickel inventory and Shanghai nickel warehouse receipts increased. Some Indonesian projects are in progress, and the expected price of Indonesian domestic - trade nickel ore is decreasing [19][20][21]. - **Main Logic**: Market sentiment dominates the market, and the industrial fundamentals are weakening. The supply of nickel ore is relatively loose, and the overall supply - demand of nickel - related products is also loose. The high inventory of LME and Shanghai nickel futures suppresses nickel prices. There are many supply - side interference policies in major resource - producing countries, and the RKAB quota progress needs to be monitored [21][22]. 3.8 Stainless Steel - **View**: Driven by the weakening of nickel prices, the stainless - steel market is oscillating downward. The medium - term outlook is oscillating [23]. - **Information Analysis**: The stainless - steel futures warehouse receipts decreased. The spot premium of stainless steel in Foshan was positive. The average price of high - nickel pig iron increased [23]. - **Main Logic**: The cost support for stainless - steel prices has strengthened. The stainless - steel production decreased slightly in November and is expected to decline further in December. The social inventory has not accumulated significantly, but there is still pressure in the off - season. Overall, stainless - steel prices are expected to oscillate within a range [23]. 3.9 Tin - **View**: Inventory is continuously accumulating, and tin prices are oscillating at a high level. The medium - term outlook is oscillating with an upward bias [24][25]. - **Information Analysis**: On December 15, the LME tin warehouse receipts decreased, and the Shanghai tin warehouse receipts increased. The spot price of tin decreased [24][25]. - **Main Logic**: Supply - side issues are the core concern. The resumption of production in the Wa State's Manxiang mining area is slow, and the supply of refined tin in Indonesia and Africa is restricted. The supply of tin ore is tightening, and the processing fee is low, limiting the increase in refined tin production. The demand for tin is expected to increase due to the global economic environment and the development of related industries. Therefore, the supply - demand fundamentals support the upward movement of tin prices [25].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The macro - expectation is repetitive but stable, and base metals will oscillate and rise. In the short - to - medium term, supply disruptions will continue to support base metal prices, but macro support has weakened. One can cautiously focus on the opportunity for aluminum ingot price to catch up, and also consider low - absorption and long - position opportunities for copper after its price decline. In the long term, there are still expectations of potential incremental stimulus policies in China, and supply disruptions in copper, aluminum, and tin persist, so the supply - demand situation is expected to tighten, and the price trends of copper, aluminum, and tin are optimistic [1]. - For different varieties: copper prices will adjust in the short term; alumina prices will be under pressure and oscillate; aluminum prices will oscillate upwards; aluminum alloy prices will oscillate strongly; zinc prices will oscillate at a high level; lead prices will oscillate; nickel prices will oscillate; stainless steel prices will oscillate; tin prices will oscillate strongly [2]. 3. Summary According to Relevant Catalogs 3.1行情观点 3.1.1 Copper - **Viewpoint**: Due to tight US monetary liquidity, copper prices have adjusted in the short term. The medium - term outlook is oscillating strongly. - **Analysis**: The Fed cut interest rates by 25 basis points, and the decision on further rate cuts in December is undetermined. The US financial system's capital situation has worsened. In October, China's electrolytic copper production decreased both month - on - month and year - on - year. As of November 6, copper inventory increased, and the spot price was at a premium. - **Logic**: Macroscopically, the Fed's rate cut and Powell's slightly hawkish speech, along with concerns about tight US money market liquidity, led to a decline in risk asset prices, including copper. In terms of supply - demand, copper mine supply disruptions increased, processing fees were low, and the cost and difficulty of scrap copper recycling increased, causing a contraction in supply. On the demand side, copper inventory did not decline significantly, but the spot price turned to a premium, indicating stronger downstream purchasing willingness. If inventory continues to decline, the price adjustment may be limited [7][8]. 3.1.2 Alumina - **Viewpoint**: The fundamentals are still in surplus, and alumina prices will be under pressure and oscillate. - **Analysis**: On November 6, alumina spot prices in different regions showed different trends, and the warehouse receipt increased. - **Logic**: Recently, macro sentiment has amplified price fluctuations. Fundamentally, high - cost production capacity has fluctuations, and supply contraction is not obvious. China is still in a strong inventory - building trend, and ore prices have loosened slightly. The price is under pressure, but as the valuation enters a low - level range, price fluctuations may increase [9]. 3.1.3 Aluminum - **Viewpoint**: With the linkage between stocks and futures, aluminum prices will oscillate upwards. The medium - term outlook is oscillating strongly, and the price center is expected to rise. - **Analysis**: On November 6, the average price of AOO aluminum increased, aluminum bar inventory increased, electrolytic aluminum ingot inventory decreased, and the warehouse receipt decreased. There were also news about power agreements of aluminum plants and environmental protection warnings in some regions. - **Logic**: Macroscopically, the US government shutdown and the Sino - US tariff suspension consensus have made the macro sentiment repetitive. On the supply side, domestic production capacity and operating rate are high, and there are environmental protection policies, while overseas supply has marginal disruptions. On the demand side, the traditional peak season has passed, terminal demand is stable, and social inventory reduction has slowed down. Overall, in the short term, the price will oscillate strongly, and in the medium term, supply growth is limited, and demand is resilient [12][13]. 3.1.4 Aluminum Alloy - **Viewpoint**: Scrap aluminum supply remains tight, and the price will oscillate strongly in the short term and oscillate in the medium term. - **Analysis**: On November 6, the price of ADC12 increased, and the average price of AOO aluminum also increased. The US Aluminum Association proposed to ban UBC scrap exports, indicating local shortages. The estimated retail market scale of narrow - sense passenger cars in October decreased month - on - month. - **Logic**: In terms of cost, scrap aluminum supply is tight, providing strong cost support. On the supply side, the weekly operating rate increased slightly, but some alloy plants face the risk of production cuts. On the demand side, there is marginal improvement, especially in automobile sales. Overall, with strong cost support and weak improvement in supply - demand, the price will oscillate strongly in the short term [14]. 3.1.5 Zinc - **Viewpoint**: The export window has opened, and zinc prices will oscillate at a high level in the short term and may decline in the long term. The overall performance is oscillating. - **Analysis**: On November 6, the spot price of zinc in different regions was at a discount. As of November 6, zinc ingot inventory decreased. A mine in Australia postponed high - grade zinc ore mining due to an earthquake. - **Logic**: Macroscopically, Sino - US economic and trade relations are easing, and the 15th Five - Year Plan is becoming clear. On the supply side, zinc ore supply has loosened in the short term, processing fees have increased, and smelters' profitability is good, with high production willingness. The export window has opened, relieving domestic supply pressure. On the demand side, the domestic market is entering the off - season, and new orders are limited. Overall, domestic social inventory may not accumulate further, and the LME's rule change eases the squeeze - out pressure on LME zinc [16]. 3.1.6 Lead - **Viewpoint**: Social inventory is slightly accumulating, and lead prices will oscillate strongly. - **Analysis**: On November 6, the price of scrap electric vehicle batteries remained stable, the price of lead ingots decreased, and social inventory increased. Some lead ingots were transferred to social warehouses for delivery, and some regenerative lead smelters resumed production. - **Logic**: In the spot market, the premium remained stable. On the supply side, regenerative lead smelters resumed production, but primary lead smelters had many overhauls, and weekly production decreased slightly. On the demand side, although some lead - acid battery factories had short - term production cuts due to high lead prices, it is the peak demand season, and the overall operating rate is high. Considering supply - demand, cost, and macro factors, lead prices will oscillate strongly [17][19]. 3.1.7 Nickel - **Viewpoint**: Market sentiment has recovered, and nickel prices will oscillate. - **Analysis**: On November 6, LME nickel inventory decreased slightly, and Shanghai nickel warehouse receipts decreased. Indonesia strengthened the crackdown on illegal nickel mining, and a company in Mongolia is exploring copper - nickel projects. - **Logic**: Currently, market sentiment dominates the market, and the static valuation is stable. Fundamentally, the supply of nickel ore is relatively loose, the production of intermediate products has recovered, nickel salt prices have weakened slightly, and the market is in surplus with large inventory accumulation. One should focus on changes in LME nickel inventory and RKAB quotas [20][22]. 3.1.8 Stainless Steel - **Viewpoint**: Warehouse receipts continue to decline, and stainless steel prices will oscillate. - **Analysis**: The latest stainless steel futures warehouse receipt inventory decreased. The spot price of stainless steel in Foshan had a premium. The average price of high - nickel pig iron decreased. The Indonesian government allocated special funds for mining and smelting projects. - **Logic**: The prices of nickel - iron and chromium have weakened, reducing cost support. In October, stainless steel production increased, but downstream demand's acceptance of price increases is limited. Social inventory has slightly accumulated, and there may be inventory pressure in the off - season. Overall, the price will oscillate within a range [23][26]. 3.1.9 Tin - **Viewpoint**: Shanghai tin inventory continues to decline, and tin prices will oscillate strongly. - **Analysis**: On November 6, LME tin warehouse receipt inventory increased, Shanghai tin warehouse receipt inventory decreased, and the price of tin ingots increased. - **Logic**: Supply constraints still exist, providing strong support for tin prices. In Wa State, production increase may be delayed, and in Indonesia, the supply of refined tin is expected to tighten. In the future quarter, the shortage of tin ore in China is difficult to significantly ease, and processing fees will remain low. However, after Yunxi's resumption of production, the operating rate of refined tin has increased, and inventory may accumulate slightly, limiting price increases [26]. 3.2行情监测 No specific analysis content provided in the given text, only variety names are listed, so no detailed summary can be made. 3.3中信期货商品指数 - On November 6, 2025, the comprehensive index, including the commodity index, the commodity 20 index, and the industrial products index, all showed an upward trend, with increases of 0.50%, 0.61%, and 0.45% respectively. The non - ferrous metals index increased by 0.64% on that day, decreased by 0.07% in the past 5 days, decreased by 0.30% in the past month, and increased by 7.44% since the beginning of the year [151][153].
