Report Industry Investment Rating - Industrial silicon: Oscillating / Polysilicon: Oscillating [4] Core Viewpoints of the Report - For industrial silicon, the current production cut scale is insufficient to reverse the inventory accumulation pattern, and it is expected to continue accumulating inventory in Q1 26 during the dry - season. It is advisable to focus on short - selling opportunities after rebounds. For polysilicon, although there may be a situation of "high prices but low trading volume" from January to February, the peak - season expectation cannot be falsified, so it is more advisable to focus on long - buying opportunities at low prices [3][17][18] Summary According to Relevant Catalogs 1. Industrial Silicon/Polysilicon Industry Chain Prices - The Si2605 contract of industrial silicon increased by 190 yuan/ton week - on - week to 8880 yuan/ton. The SMM spot East China oxygen - blown 553 increased by 50 yuan/ton to 9250 yuan/ton, while Xinjiang 99 decreased by 50 yuan/ton to 8700 yuan/ton. The PS2605 contract of polysilicon decreased by 1290 yuan/ton to 58955 yuan/ton. The average transaction price of polysilicon N - type re - feedstock increased by 700 yuan/ton week - on - week to 53900 yuan/ton [10] 2. Intensified Production Cuts in Organic Silicon, Rising Prices of Silicon Wafers and Batteries Industrial Silicon - The main contract of industrial silicon futures fluctuated upward this week. Some large factories in Xinjiang increased production by 2 furnaces and some had 2 furnaces under maintenance, with the total unchanged. Inner Mongolia had 4 furnaces under maintenance, and Gansu increased production by 4 furnaces after previous maintenance. SMM industrial silicon social inventory increased by 0.2 million tons week - on - week, and sample factory inventory increased by 0.31 million tons. The industrial silicon market is in tight balance in December, but may accumulate inventory in Q1 next year if production cuts are not sustained. After the price increase, some large factories started hedging sales, and downstream purchasing enthusiasm was low. Attention should be paid to whether the polysilicon sector will cut production [12] Organic Silicon - The price of organic silicon remained stable this week. Some companies reduced production loads. The overall enterprise start - up rate was 68.33%, with a weekly output of 45200 tons, a week - on - week decrease of 3.42%. The inventory was 44000 tons, a week - on - week decrease of 2%. With the supply contraction and inventory decline, the price may rise steadily after the pre - festival restocking demand is released [12][13] Polysilicon - The main contract of polysilicon futures fluctuated downward this week. After the establishment of the platform company, the spot price of polysilicon rose again. As of December 25, the factory inventory of polysilicon enterprises was 303,000 tons, a week - on - week increase of 10,000 tons. The production schedule in January is not clear, but the shipment volume will be significantly reduced to 60,000 - 80,000 tons. There may be a situation of "high prices but low trading volume" from January to February, but the polysilicon spot is still considered bullish [14] Silicon Wafers - The price of silicon wafers strengthened significantly this week. The expected production volume in December is 45GW and may decline further in January. As of December 25, the inventory of silicon wafer factories was 21.7GW, a week - on - week increase of 0.19GW. Four leading enterprises raised their quotes on the 25th. Attention should be paid to whether batteries and components can pass on the price [15] Battery Cells - The price of battery cells rose rapidly this week due to the rising silver paste price. As of December 22, the inventory of Chinese photovoltaic battery export factories was 10.06GW, a week - on - week increase of 0.62GW. Leading battery cell manufacturers raised their prices again, but the price increase of components was less than expected. If the price cannot be passed on, the start - up rate in January is expected to decline [15] Components - The price of components remained basically stable this week. Affected by the rising battery cell price, component enterprises raised their quotes. The domestic end - of - year installation demand ended, and overseas orders had no significant increase. Professional component factories will start reducing production in January, and the domestic production volume in January may fall below 30GW. As of December 15, the finished - product inventory of Chinese photovoltaic components was 31.7GW, a week - on - week increase of 0.5GW [16] 3. Investment Recommendations - For industrial silicon, although the market rumors and positive sentiment in the commodity market drove the price up, from the fundamental perspective, it is recommended to focus on short - selling opportunities after rebounds. For polysilicon, it is recommended to focus on long - buying opportunities at low prices, but investors should hold positions carefully due to large price fluctuations and risk - control measures from the exchange [3][17][18] 4. Hot News Compilation - The Guangzhou Futures Exchange adjusted the minimum opening order quantity, trading fee standard, and trading limit of polysilicon futures contracts. The Zhihui Photovoltaic adjusted the price limit range and trading margin standard of industrial silicon and polysilicon futures contracts during the New Year holiday in 2026 [19][20] 5. High - Frequency Data Tracking of the Industry Chain - This part mainly includes various data charts of industrial silicon, organic silicon, polysilicon, silicon wafers, battery cells, and components, such as the price, output, inventory, and profit data of each link, with specific data sources provided [21][30][34]

Core Viewpoint - The industrial silicon market is experiencing weak supply and demand, leading to price fluctuations constrained by cost support and weak demand [1][2]. Supply Side - Production remains stable across major production areas, particularly in Xinjiang, but price differentiation in the spot market has increased due to volatility in futures prices [2]. - Some manufacturers are either maintaining firm quotes, refraining from quoting, or selling below market average to improve cash flow, resulting in a low operating rate [2]. - The current low-price environment is suppressing production enthusiasm, with many existing capacities used for internal settlements or long-term sales [2]. - Overall, the supply side is supported by costs, but slow inventory depletion and reduced downstream production are leading to inventory accumulation in some regions [2]. Demand Side - Demand from downstream sectors, particularly organic silicon and polysilicon industries, is weak, leading to reduced procurement of industrial silicon [2]. - The photovoltaic industry is generally experiencing losses, further suppressing industrial silicon consumption [2]. - Although the aluminum alloy market saw a slight increase in futures prices (from 21,110 CNY/ton to 21,480 CNY/ton), it has limited impact on driving demand for industrial silicon [2]. Price Trends - The comprehensive price of industrial silicon in China as of December 24 is 9,245 CNY/ton, down 5 CNY/ton from the previous week [1][3]. - Specific prices include 5 at 8,713 CNY/ton (down 94 CNY/ton) and 4 at 9,169 CNY/ton (up 51 CNY/ton) [1][3]. - Regional prices vary, with Xinjiang at 8,810 CNY/ton, Yunnan at 10,005 CNY/ton, and Sichuan at 10,050 CNY/ton [1][3]. Market Outlook - The industrial silicon market is expected to continue its range-bound fluctuations in the short term, with future trends dependent on the recovery pace of downstream demand and the progress of inventory depletion [2].

Core Viewpoint - The industrial silicon market is experiencing weak supply and demand, leading to price fluctuations constrained by cost support and weak demand [1][3]. Supply Side - Production remains stable across major production areas, particularly in Xinjiang, but price differentiation has increased due to volatile futures prices. Some manufacturers are either maintaining high quotes or choosing not to quote at all, while others are selling below market average to improve cash flow [2]. - The operating rates in regions like Inner Mongolia, Sichuan, Yunnan, and Gansu are at low levels due to a prolonged low-price environment, which has suppressed production enthusiasm. Overall transaction volumes remain low despite some attempts to support prices [2]. - The pricing mechanism is becoming more financialized, with a growing trend of using a "futures price + basis" procurement model, enhancing the linkage between spot prices and futures markets [2]. Demand Side - Demand from downstream sectors, particularly the organic silicon and polysilicon industries, is weak, leading to reduced procurement of industrial silicon. The overall support for demand is insufficient, with risks of further demand contraction highlighted by losses across the photovoltaic industry chain [2]. - Although the aluminum alloy market has seen a slight increase in futures prices (from 21,110 yuan/ton to 21,480 yuan/ton), this has not significantly boosted demand for industrial silicon [2]. Market Overview - The industrial silicon market is characterized by weak supply and demand, with inventory accumulation and continued price fluctuations. While supply is supported by costs, slow inventory depletion and reduced downstream production are leading to demand contraction, resulting in price resistance [3]. - Short-term price expectations indicate continued range-bound fluctuations, with future trends heavily dependent on the recovery pace of downstream demand and the progress of inventory depletion [3]. Price Data - As of December 24, the national average price for industrial silicon is 9,245 yuan/ton, reflecting a slight decrease of 5 yuan/ton from the previous week. Specific grades show varied price movements, with 553 at 8,713 yuan/ton (down 94 yuan/ton) and 441 at 9,169 yuan/ton (up 51 yuan/ton) [1][4]. - Regional prices vary, with Xinjiang at 8,810 yuan/ton, Yunnan at 10,005 yuan/ton, and Sichuan at 10,050 yuan/ton [4].
