Report Industry Investment Rating - Not provided in the given content Core Viewpoints - Grasberg's unexpected copper production cut will change the global copper supply pattern in the next 12 - 15 months. With no significant increase in adjusted copper mine supply this year and no increase next year without the resumption of the Panama mine, the contradiction at the mine end is further intensified. The market sentiment and capital allocation for copper are expected to turn around, and the medium - term allocation value of copper is still favored [1]. - For aluminum, the short - term fundamentals are acceptable. Pay attention to demand, hold at low prices under the low - inventory pattern, and pay attention to far - month inter - month and internal - external reverse arbitrage [1]. - Zinc prices fluctuated this week. The short - term unilateral trend is weakly volatile, and it is recommended to wait and see; for internal - external arbitrage, partial profit - taking can be considered for internal - external positive arbitrage [2]. - The fundamentals of nickel and stainless steel are generally weak. In the short term, the macro - aspect follows the anti - involution expectation, and the policy side has a certain motivation to support prices [3][4]. - Lead prices are expected to maintain a weak and volatile trend next week, in the range of 16,800 - 17,000 [7]. - For tin, the short - term domestic fundamentals maintain a situation of weak supply and demand. It is recommended to wait and see in the short term, short lightly when the price is above 275,000 yuan/ton, and hold near the cost line in the medium - long term [10]. - The short - and medium - term supply and demand of industrial silicon are in a balanced state, and the long - term price is expected to fluctuate at the cycle bottom [11]. - The price of lithium carbonate fluctuates. The price elasticity is high after the supply - side disturbance speculation is realized, and the downward price support is strong before the disturbance occurs [11]. Summary by Metals Copper - Freeport's Indonesian subsidiary's泥石流 accident postponed Grasberg's resumption of production, reducing the 2026 copper guidance by about 35% (equivalent to a reduction of about 270,000 tons of copper and about 1.04 million ounces of gold). The adjusted copper mine supply has no significant increase this year and next year without the resumption of the Panama mine [1]. - Fund long positions are gradually increasing, but macro and bulk CTA funds are still focused on precious metals. The gold - copper ratio is at a low historical quantile. With the structural gap in copper fundamentals emerging, the market sentiment and capital allocation for copper are expected to improve [1]. - Copper currently benefits from the global fiscal and monetary double - loose policy, and there is still room for subsequent interest rate cuts. It is advisable to consider laying out medium - term long positions below 79,000 - 79,500, or selling put options below 78,000 [1]. Aluminum - Supply has increased slightly, with aluminum ingot imports providing an increase from January to August. Downstream开工 has improved, and the production schedule of photovoltaic modules has stabilized. Pay attention to whether overseas demand stabilizes after the decline [1]. - In September, inventory decreased slightly, and it is expected to increase seasonally in October. The short - term fundamentals are acceptable, and attention should be paid to demand [1]. Zinc - This week, zinc prices fluctuated. The domestic TC decreased further, and the imported TC increased further. From the fourth quarter to the first quarter of next year, domestic zinc mines will be marginally tighter, while overseas mine production increased more than expected in the second quarter. In August, China imported 460,000 tons of zinc ore, a cumulative year - on - year increase of 43% [2]. - In October, smelting production recovered slightly month - on - month. When the domestic zinc mine processing fee declines, attention should be paid to the impact of sulfuric acid and silver prices on total profits [2]. - Domestic demand is seasonally weak, with limited growth but certain resilience; overseas, European demand is average, and some smelters face production resistance due to processing fees [2]. - Domestic social inventory fluctuates, and overseas LME inventory decreases. The current pattern of strong overseas and weak domestic may further diverge, and the export window is approaching. Some smelters and traders are preparing for exports [2]. Nickel and Stainless Steel - For nickel and stainless steel, supply is expected to see a slight resumption of production by steel mills. Demand is mainly for rigid needs. Nickel - iron prices remain stable, and chromium - iron prices for stainless steel increase slightly [3][4]. - Nickel inventories in Xifu area increased slightly, and stainless steel inventories in Xifu area decreased. Warehouse receipts for both decreased slightly [3][4]. Lead - This week, lead prices rose due to macro - factors. On the supply side, the scrap volume is weaker year - on - year. The expansion of recycling plants has led to a shortage of waste batteries. With low profits, recycled lead maintains low - level production. From April to August, the operation of concentrate mines increased, but due to smelting profits, supply fell short of demand, and TC quotes declined in a chaotic manner [7]. - On the demand side, the inventory of battery products is high. During the National Day holiday, battery production increased, and demand improved slightly. The refined - scrap price difference is - 75, and the long - term supply of recycled lead in Henan is tight. LME registered warehouse receipts decreased by 2,000 tons [7]. - In August, primary lead supply remained flat, and recycled lead production decreased. In September, both production cuts and resumptions occurred in recycled lead, and primary lead supply is expected to remain flat. Demand has improved slightly, but inventory is at a high level, and the overall inventory reduction needs to be verified [7]. Tin - This week, tin prices fluctuated widely. On the supply side, the processing fee for tin mines is at a low level, and some domestic smelters have cut production. Yunnan Tin had maintenance in early September for about 45 days. Overseas, imports from Wa State were still low in August but gradually recovered from late September to October, and it is expected to maintain above 600 metal tons. Indonesia's tin export is expected to resume in mid - to late September [10]. - On the demand side, the elasticity of solder is limited, mainly supported by rigid demand. When prices declined rapidly this week, downstream replenishment willingness was strong, and combined with National Day holiday replenishment, inventory reduction was significant. Overseas, Indonesia is gradually recovering, and LME inventory has rebounded from a low level [10]. Industrial Silicon - This week, leading enterprises in Xinjiang continued to resume production, with the latest number of operating furnaces reaching 82, an increase of 5 from last week. Currently, the operation in Sichuan and Yunnan is stable, with a monthly output close to 120,000 tons. Some factories in the southwest may gradually cut production in the future [11]. - In September, the supply - demand was in a balanced state, and the core of the balance change is the rhythm and amplitude of Hesheng's resumption of production. In the short term, affected by the resumption rhythm of the southwest and Hesheng, the supply - demand will remain balanced in September and October. In the long term, the over - capacity of industrial silicon is still large, and the price is expected to fluctuate at the cycle bottom based on the seasonal marginal cost [11]. Lithium Carbonate - This week, lithium carbonate prices fluctuated. On the raw material side, overseas mines have a strong willingness to support prices, and traders are reluctant to sell, but salt factories have a low acceptance of high - priced lithium ore [11]. - On the lithium salt side, the pre - holiday replenishment rhythm was strong first and then weak this week and is now approaching the end. The spot basis is stable and weak, with some discounts expanding by 100 - 200 yuan. The transaction of electric - grade lithium carbonate in the market is still mainly at a discount, and inquiries for high - priced goods are relatively scarce [11]. - Lithium carbonate is still in the capacity expansion cycle, and the static supply - demand pattern is still in surplus. With the help of the seasonal peak season and the explosion of energy storage demand, the monthly balance after CATL's gradual production cut has turned to continuous inventory reduction, but the amplitude is average [11].

1. Report Industry Investment Rating - Not provided in the content 2. Core View of the Report - The price of industrial silicon has seasonal inventory accumulation and depletion, but compared with the industry inventory of over 1 million tons, the fundamental contradiction is not obvious. After the previous hedging, short - term price decline is difficult to cause production cuts, but the price needs to break through 10,000 yuan/ton to bring obvious supply increments in the dry season or the next wet season. With the cost floor identified, the lower limit of the industrial silicon price may be clearer. In Q4, the main contract is expected to trade in the range of 8,000 - 10,000 yuan/ton, and it is recommended to focus on the opportunity of buying on dips at the lower end of the range [78]. 3. Summary by Relevant Catalogs 25Q3 Market Review - In 25H1, the price of industrial silicon dropped significantly due to inventory accumulation during the dry season, resumption of production by large manufacturers, and cost collapse driven by falling coal prices. In 25Q3, the price rebounded sharply due to the continuous strengthening of the basis, outflow of warehouse receipts, lower - than - expected resumption of production by large manufacturers, and the "anti - involution" trading. After the "anti - involution" trading declined, the price fluctuated between 8,200 - 9,200 yuan/ton [3]. Cost Analysis - **Electricity Price**: The cost floor in terms of electricity price has emerged. In Xinjiang, self - supplied electricity is about 0.2 yuan/kWh, and subsidized purchased electricity is about 0.3 yuan/kWh, with 0.35 yuan/kWh in Yili. In Yunnan, the electricity price rises slightly in the normal - water period in October and increases by 0.15 - 0.2 yuan/kWh in the dry season from November to December. In Sichuan, the electricity price rises by 0.05 - 0.1 yuan/kWh in the normal - water period in November and by 0.16 - 0.21 yuan/kWh in the dry season in December compared with the wet season [8][10]. - **Raw Materials**: The cost floor for raw materials has also emerged. The cash cost of self - supplied electricity in Xinjiang is 6,800 yuan/ton, and that of purchased electricity is 7,800 yuan/ton. The cash cost in the wet season in Sichuan is 8,500 - 9,100 yuan/ton, and in Yunnan, it is 9,900 yuan/ton. In the dry season, the cash cost in Baoshan is 11,500 yuan/ton, and in other south - western regions, it is 12,500 yuan/ton [22][23][30]. Supply Analysis - **Seasonal Production Cuts**: In the dry season, the supply elasticity is weakened by hedging. Xinjiang's large manufacturers plan to increase the number of furnaces in the eastern base to 50, and may further increase to 60. Yunnan and Sichuan will start production cuts at the end of October, with Yunnan's operation possibly dropping to more than 20 furnaces and Sichuan's to about 35 furnaces. Inner Mongolia's polysilicon integrated and self - supplied electricity - advantaged capacities are operating at full capacity. In Gansu, the operation is expected to change little [31]. - **Potential Supply Pressure**: There are many built - but - not - yet - commissioned capacities, posing a large potential supply pressure. Newly commissioned capacities include Tongwei Baotou, Tongwei Guangyuan, Xin'an Yanjin, and Yongchang Silicon Industry. Built but postponed commissioning includes Qiya Silicon Industry, Qinghai Hongshi, Hesheng Zhaotong, Trina Solar, and Shangnan Zhongjian [37][38]. Demand Analysis - **Polysilicon**: After the "anti - involution" trading, the mainstream transaction price of dense materials from first - tier enterprises rose to 50 - 52 yuan/kg, with a net profit margin of over 10%. The upstream factory inventory is 20 - 21 million tons, mainly concentrated in leading enterprises. The downstream raw material inventory is over 2 months. From January to September 2025, the polysilicon output was 951,000 tons, a year - on - year decrease of 33%. Considering the dry - season production cuts and the resumption expectations of some enterprises, the polysilicon production schedule for Q4 2025 is expected to be 376,000 tons, a year - on - year increase of 8% [50]. - **Organic Silicon**: The real estate market remains weak. In terms of photovoltaic, from January to September, the domestic component output of Chinese enterprises was 412.3GW, a year - on - year increase of 4%. Considering the weakening demand, the production schedule for Q4 2025 is expected to be 136GW, a year - on - year decrease of 3%. For new - energy vehicles, from January to August, the sales volume was 9.592 million, a year - on - year increase of 36%. Due to the high base in Q4 last year, the annual growth rate is adjusted down to 24%, with a year - on - year increase of 9.5% in Q4. In terms of exports, from January to August, the export volume of primary - form polysiloxane was 373,000 tons, a year - on - year increase of 1%. However, the US tariff adjustment is expected to reduce exports to the US. From January to August, the output of organic silicon intermediates was 1.653 million tons, a year - on - year increase of 18%. The production of organic silicon DMC in Q4 2025 is expected to be 677,000 tons, the same as the previous year [51][62][68]. - **Aluminum Alloys and Exports**: From January to August, the output of primary aluminum alloys was 941,000 tons, a year - on - year increase of 1%, and the output of recycled aluminum alloys was 4.056 million tons, a year - on - year increase of 4%. Q4 is the seasonal peak season for aluminum alloys. Aluminum plants mainly purchase industrial silicon as a rigid demand, buying on dips and consuming inventory at other times. The demand for industrial silicon from aluminum alloys in Q4 2025 is expected to be 230,000 tons, a year - on - year increase of 5%. From January to August, the export of industrial silicon was 490,000 tons, a year - on - year increase of 30% [69]. Supply - Demand Balance and Price Outlook - **Supply - Demand Balance**: On the supply side, with Xinjiang's large manufacturers' eastern base operating 50 furnaces, the operating rate in the southwest drops significantly in the dry season. On the demand side, polysilicon production is affected by dry - season cuts and some enterprises' resumption, organic silicon production remains the same year - on - year, and aluminum alloy demand increases slightly year - on - year. Inventory accumulates in October, and about 50,000 tons are depleted from November to December in the dry season. However, if Xinjiang's large manufacturers fully resume production, it may be difficult to deplete inventory in November and only a small amount will be depleted in December [73]. - **Price Outlook**: The lower limit of the industrial silicon price may be clearer with the cost floor identified. The main contract in Q4 is expected to trade in the range of 8,000 - 10,000 yuan/ton [78].
