南华期货工业硅产业周报：下方空间有限，时间换空间-20251214

1. Report Industry Investment Rating No information provided in the report. 2. Core Viewpoints of the Report - In the short - term, there is no driving force, and the market shows a weak and volatile pattern. However, it is necessary to be vigilant about environmental protection speculation in winter. In the medium - to - long - term, the downside space for industrial silicon prices is limited, and it is cost - effective to buy long - term contracts during peak seasons at low prices. The price trend of industrial silicon is also closely related to the price fluctuations of related products such as polysilicon and coking coal [2]. 3. Summary by Relevant Catalogs 3.1 Core Contradictions and Strategy Suggestions 3.1.1 Core Contradictions - The core driving factors for the future price trend of industrial silicon futures include the progress of eliminating backward production capacity under the "anti - involution" background of the industry, production cuts on the supply side due to environmental protection constraints or rising costs, and the expected production cuts on the demand side due to weak terminal sales. The industry has expectations for eliminating backward production capacity, but due to the large number of private enterprises and scattered layout in the industrial silicon industry, there is a lack of confidence in effective capacity clearance through industry self - regulation. - Electricity costs account for 30% of the production cost of industrial silicon, and coal price fluctuations affect electricity costs and then industrial silicon prices. In December, the operating rate of industrial silicon producers is expected to decline. Downstream, the polysilicon industry is reducing production, the silicone monomer plants have maintenance plans, and only the aluminum alloy industry maintains a stable operating rate [1]. 3.1.2 Trading Logic - Near - term trading logic (before the end of 2025): Environmental protection disturbances, and expected production cuts on both the supply and demand sides. - Long - term trading logic (after early 2026): The progress of eliminating backward production capacity under the "anti - involution" background of the industry, and continuous attention to demand [4]. 3.1.3 Industrial Operation Suggestions - Sales management: For enterprises planning to produce industrial silicon in the future and worried about price drops during sales, they can sell corresponding futures contracts and use a combined options strategy (buy put options and sell call options) with a recommended hedging ratio of 20%. - Procurement management: For enterprises planning to produce polysilicon, silicone, or aluminum alloy in the future, if the finished product price is not correlated, they can buy corresponding futures contracts with a recommended hedging ratio of 30% and use a combined options strategy (sell put options and buy call options) with a ratio of 10%. If the finished product price is correlated, they can sell corresponding futures contracts and use a combined options strategy (buy put options and sell call options) with a ratio of 20%. - Inventory management: For enterprises with high industrial silicon inventory and worried about inventory depreciation due to price drops, they can short futures contracts and use a combined options strategy (sell call options and buy put options) with recommended hedging ratios of 20% and 10% respectively [5]. 3.2 Important Information and Events to Watch 3.2.1 This Week's Important Information Review - On December 8, Jianghan New Materials announced that a 60,000 - ton/year trichlorosilane plant was put into trial operation in October this year, 10,000 tons of silane production capacity is planned to be put into trial operation in December, and another 10,000 tons each will be put into trial operation in mid - and late - next year. In 2027, optical fiber - grade silicon tetrachloride and electronic - grade tetraethyl orthosilicate plants will be gradually built. - On December 8, GCL Technology announced that its subsidiaries and other parties signed a partnership agreement to establish a limited partnership, which plans to acquire a 42.469% stake in Inner Mongolia Xinyuan Silicon Materials Technology Co., Ltd. from Hongyuan Green Energy and Tibet Ruihua for a total consideration of RMB 2.01 billion [6]. 3.2.2 Next Week's Events to Watch No events to watch were mentioned in the report [7]. 3.3 Disk Interpretation 3.3.1 Price, Volume, and Capital Analysis - The closing price of the industrial silicon weighted index contract on Friday was 8,412 yuan/ton, a week - on - week decrease of 4.66%. The trading volume was 619,800 lots, a week - on - week increase of 113.65%, and the open interest was 460,100 lots, an increase of 19,000 lots week - on - week. The monthly spread between SI2601 and SI2605 was in a back structure, with a week - on - week increase of 90 yuan/ton. The number of warehouse receipts was 8,619 lots, an increase of 1,331 lots week - on - week. - The industrial silicon weighted futures price quickly fell below the 5 - day moving average this week. The disk showed the characteristic of "short - position increase and price decline". The current price quickly fell below the lower track of the Bollinger Band, and the Bollinger Bandwidth showed signs of widening. It is necessary to focus on the support level of 8,000 yuan/ton, and from Thursday to Friday, there was a characteristic of "short - position exit and price stabilization" [10][11]. 3.3.2 Option Analysis - The 20 - day historical volatility of industrial silicon has been strengthening in the past week, indicating that the actual price fluctuation range has been gradually expanding. The implied volatility of at - the - money options has also been strengthening. The PCR of option open interest has been rising, indicating an increasing bearish sentiment in the market [13]. 3.3.3 Term Structure Analysis - The term structure of industrial silicon futures shows a back structure, which is relatively stable. The basis of the main industrial silicon contract is at a relatively high level [17][19]. 3.3.4 Spot Data of the Silicon Industry Chain - The prices of different grades of industrial silicon in various regions have shown different degrees of decline. The prices of industrial silicon powder have also decreased. The price of trichlorosilane and polysilicon N - type price index remained unchanged, the price of silicone DMC was stable, and the price of aluminum alloy ADC12 increased slightly [22]. 3.4 Valuation and Profit - Since hitting the profit low in May, the average profit of the industrial silicon industry has been in a continuous recovery channel. The profit of the polysilicon industry is currently stable, providing important support for the demand of industrial silicon. The profit of the aluminum alloy industry is showing a weakening trend, while the profit of the silicone industry is recovering [23]. 3.5 Fundamental Analysis 3.5.1 Upstream - Industrial Silicon - The weekly production and operating rates of industrial silicon from different data sources showed different trends. The weekly production of some data sources increased, while others decreased. The operating rates also showed mixed trends [30]. - The inventory data of industrial silicon in different regions and warehouses showed different changes [47][48][50]. 3.5.2 Downstream - Polysilicon - The weekly production of domestic polysilicon decreased, and the operating rate also declined. The total inventory of polysilicon increased slightly, with different changes in the inventory of production enterprises, silicon wafer enterprises, and warehouse receipts [51][52][54]. 3.5.3 Downstream - Aluminum Alloy - The operating rates of primary and secondary aluminum alloys decreased slightly, and the inventory of primary aluminum alloy decreased, while the inventory of secondary aluminum alloy decreased significantly [58][59]. 3.5.4 Downstream - Organic Silicon - The weekly production of organic silicon DMC decreased, with a week - on - week decrease of 6.12% [64]. 3.5.5 Terminal - The report shows the data trends of China's commercial housing sales area, automobile monthly production, and photovoltaic monthly new installed capacity [67].
