国信期货硅产业链季报 工业硅、多晶硅 政策交易后期，价格震荡前行 / 国信期货研究 Page 1 2025 年 9 月 28 日 主要结论 三季度季度工业硅显性库销比已经下降至 200%以内，这主要是因为交割库 存消化幅度较大，另外因为多晶硅企业开工率上行，增加了对原材料工业硅的需 求。到四季度，西南地区中小企业会陆续停炉，但产量能否快速下降还要看西北 地区开工率变化。在下游需求方面，三季度多晶硅企业生产利润尚可，多晶硅产 量高企，但国内光伏终端需求偏低迷，后期多晶硅想要维持供需平衡必须下调开 工率，对原材料的需求量也会有所减少。有机硅方面，企业生产亏损依然严重， 地产需求低迷且尚未有大规模刺激政策，有机硅终端需求难有改善，后期有机硅 DMC 产量可能维持在 21 万吨左右，对原材料工业硅需求偏弱。铝合金产量保持 稳定增长态势，终端汽车需求旺盛，对工业硅需求尚可。出口需求在下半年大爆 发，但四季度可能是前高后低的情况。基于当前工业硅企业的生产情况、供需数 据推算四季度工业硅行业显性库销比环比三季度可能会上行，但可能不会达到二 季度的水平。工业硅价格可能呈现震荡走势，综合季节性来看工业硅期货价格波 动区间可能为 ...

Report Summary 1. Industry Investment Rating No information provided. 2. Core Views - For industrial silicon, the current fundamentals have little change, and the industrial silicon futures price is mainly affected by the overall commodity sentiment and policy - related news. The valuation is low, and if there are relevant policies, the futures price may rise. For polysilicon, the supply - demand fundamentals are average, and both supply and demand are expected to decline in the fourth quarter. The futures price is affected by anti - involution policies and weak market reality, with large fluctuations. In the long - term, it is suitable to buy polysilicon futures at low prices [2][6]. 3. Summary by Related Content Industrial Silicon - **Market Analysis** - **Futures Price**: On September 24, 2025, the industrial silicon futures price fluctuated. The main contract 2511 opened at 8950 yuan/ton and closed at 9020 yuan/ton, a change of 0.84% from the previous settlement price. The position of the main contract 2511 was 270931 lots, and the number of warehouse receipts was 49925 lots, a decrease of 38 lots from the previous day [1]. - **Supply Side**: The spot price of industrial silicon rose slightly. The price of East China oxygen - fed 553 silicon was 9400 - 9600 yuan/ton, and 421 silicon was 9600 - 9800 yuan/ton. The silicon prices in various regions were relatively stable. As of September 18, the total social inventory of industrial silicon in major regions was 54.3 tons, a week - on - week increase of 0.4 tons [1]. - **Demand Side**: The price of silicone DMC was stable at 10900 - 11200 yuan/ton. Downstream enterprises maintained a rigid demand - based procurement rhythm. Although monomer factories had a stronger willingness to hold prices, price increases were restricted, and the demand was affected by the approaching National Day holiday [2]. - **Strategy** - **Unilateral**: Short - term range trading, and buy - hedging on dips. - **Others**: No strategies for inter - delivery, cross - product, spot - futures, or options [2]. Polysilicon - **Market Analysis** - **Futures Price**: On September 24, 2025, the main contract 2511 of polysilicon futures fluctuated. It opened at 50300 yuan/ton and closed at 51380 yuan/ton, a 2.41% change from the previous trading day. The position was 111187 lots, and the trading volume was 242016 lots [2]. - **Spot Price**: The spot price of polysilicon was stable. The price of N - type material was 50.00 - 55.00 yuan/kg, a decrease of 0.15 yuan/kg. The inventory of polysilicon manufacturers decreased, while the inventory of silicon wafers increased. The weekly output of polysilicon decreased by 0.50% to 31000 tons, and the output of silicon wafers increased by 0.29% to 13.92GW [2][4]. - **Enterprise Event**: Oriental Hope's Xinjiang polysilicon project will conduct annual maintenance on its three - phase production lines with capacities of 60,000 tons, 60,000 tons, and 90,000 tons respectively. This maintenance is expected to improve product quality and production stability, and it will not have a significant impact on the overall supply [5]. - **Strategy** - **Unilateral**: Short - term range trading. - **Others**: No strategies for inter - delivery, cross - product, spot - futures, or options [6].

Report Investment Rating - No investment rating information is provided in the report. Core View - Although the supply of industrial silicon has decreased due to the reduction in the start - up rate, the overall oversupply situation remains unchanged. The demand from the three major downstream industries (organic silicon, polysilicon, and aluminum alloy) for industrial silicon is generally flat. The current industry inventory is still high, and the upward momentum of industrial silicon prices will gradually weaken after reaching 9000. It is recommended to buy on dips [2]. Summary by Directory Futures Market - The closing price of the main contract is 9020 yuan/ton, up 95 yuan; the position of the main contract is 270,931 lots, down 2765 lots; the net position of the top 20 is - 67,515 lots, up 224 lots; the warehouse receipts of GZEE are 49,963 lots, up 161 lots; the closing price of the December contract is - 400 yuan/ton, down 5 yuan; the spread between the November - December contracts is - 400 yuan, down 5 yuan [2]. Spot Market - The average price of oxygen - passed 553 silicon is 9500 yuan/ton, unchanged; the average price of 421 silicon is 9700 yuan/ton, unchanged; the basis of the Si main contract is 480 yuan/ton, down 95 yuan; the spot price of DMC is 11,120 yuan/ton, up 60 yuan [2]. Upstream Situation - The average price of silica is 410 yuan/ton, unchanged; the average price of petroleum coke is 1860 yuan/ton, unchanged; the average price of clean coal is 1850 yuan/ton, unchanged; the average price of wood chips is 490 yuan/ton, unchanged; the ex - factory price of graphite electrodes (400mm) is 12,250 yuan/ton, unchanged [2]. Industry Situation - The monthly output of industrial silicon is 366,800 tons, up 33,600 tons; the weekly social inventory of industrial silicon is 552,000 tons, up 10,000 tons; the monthly import volume of industrial silicon is 1337.59 tons, up 1220.14 tons; the monthly export volume of industrial silicon is 76,642.01 tons, up 2635.83 tons [2]. Downstream Situation - The weekly output of organic silicon DMC is 44,900 tons, up 700 tons; the average price of aluminum alloy ADC12 in the Yangtze River spot market is 20,800 yuan/ton, unchanged; the weekly average price of photovoltaic - grade polysilicon is 6.54 US dollars/kg, up 0.09 US dollars/kg; the overseas market price of photovoltaic - grade polysilicon is 15.75 US dollars/kg, unchanged; the monthly export volume of unforged aluminum alloy is 29,063.7 tons, up 4154.82 tons; the weekly start - up rate of organic silicon DMC is 71.12%, down 1.59 percentage points; the monthly output of aluminum alloy is 1.635 million tons, up 99,000 tons; the monthly export volume of aluminum alloy is 29,063.7 tons, up 4154.82 tons [2]. Industry News - On September 20, the first - phase lithium carbonate project of Luopu Xihai New Energy Materials Co., Ltd. was put into operation in the Hetian Kungang Economic and Technological Development Zone (Non - ferrous Metal Industrial Park) in Luopu County, Hetian Prefecture, Xinjiang Uygur Autonomous Region [2]. Supply - side Analysis - The current start - up rate of industrial silicon is 33.12%, down 1.91% month - on - month. There are expectations of production cuts in the southwest region, and some enterprises plan to cut production. Most manufacturers in the southwest will operate until the end of October and have no plans to resume production. In the northwest region, manufacturers have stable start - up rates, especially in Yili, where large factories have expectations of resuming production. However, the overall oversupply situation has not improved [2]. Demand - side Analysis - In the organic silicon field, the market is declining, profits are decreasing, and the expectation of production increase is declining, with a negative impact on the demand for industrial silicon. In the polysilicon field, inventory and start - up rates are rising, increasing the demand for industrial silicon. But due to limited price increases in downstream links and expected contraction in long - term photovoltaic market demand, the continuous growth of polysilicon's demand for industrial silicon may be restricted. In the aluminum alloy field, inventory is rising, prices are flat, the start - up situation is stable, but demand is average, with limited pulling effect on industrial silicon. Overall, the total demand from the three major downstream industries for industrial silicon remains flat [2].
