Report Investment Rating No investment rating information is provided in the report. Core Viewpoints - The industrial silicon market shows "weak reality and weak expectation" with weak consumption, high inventory pressure, and the spot market may continue weak shock in the short term [2][3] - The polysilicon market has weakening demand, high inventory, slow de - stocking, and the 2506 contract is cautiously bullish in the short term, with upstream enterprises considering selling hedging on rallies [7][8] Summary by Related Content Industrial Silicon Market Analysis - **Futures Market**: On April 28, 2025, the industrial silicon futures price was weakly volatile. The main contract 2506 opened at 8780 yuan/ton and closed at 8800 yuan/ton, down 0.73% from the previous settlement. The position of the 2505 main contract was 188,093 lots, and the number of warehouse receipts was 69,417 lots, a decrease of 85 lots from the previous day [1] - **Supply Side**: The spot price of industrial silicon continued to decline. For example, the price of East China oxygen - passed 553 silicon was 9400 - 9700 (- 50) yuan/ton. Although some silicon plants reduced production or had maintenance due to losses, the expected production capacity in the southwest region during the wet season would gradually be released, and the supply pressure was not significantly relieved [1][2] - **Demand Side**: The demand was weak. The downstream polysilicon and organic silicon maintained low operating rates, and downstream enterprises were cautious in purchasing. The organic silicon DMC quotation was 11000 - 11800 (- 200) yuan/ton, and the overall operating rate of monomer enterprises was expected to decline [1][2] Strategy The industry's consumption is weak, and the inventory pressure is large. The spot market lacks positive drivers in the short term and may continue to oscillate weakly [3] Polysilicon Market Analysis - **Futures Market**: On April 28, 2025, the main contract 2506 of polysilicon futures fell sharply, opening at 38,390 yuan/ton and closing at 37,780 yuan/ton, a decrease of 3.05% from the previous trading day. The position of the main contract was 55,092 lots, and the trading volume was 80,862 lots [5] - **Spot Market**: The spot price of polysilicon remained stable. The polysilicon manufacturers' inventory and silicon wafer inventory increased. The polysilicon inventory was 25.90 (a month - on - month change of 3.19%), and the silicon wafer inventory was 19.53GW (a month - on - month change of 7.19%). The weekly polysilicon output was 22,800 tons (a month - on - month change of 2.24%), and the silicon wafer output was 13.38GW (a month - on - month change of - 1.40%) [5][6] Strategy - In the short term, the 2506 contract is cautiously bullish. Upstream enterprises should consider selling hedging on rallies if there is a significant rebound. - For options, consider buying a small amount of out - of - the - money call options [8]

Report Summary 1. Industry Investment Rating No industry investment rating is provided in the report. 2. Core Viewpoint The current supply - demand contradiction of industrial silicon is difficult to resolve. As the southwest production area is about to enter the flat and wet seasons in June, the cost support will weaken, and the silicon price will continue to be weak [1]. 3. Summary by Relevant Catalogs Market Conditions - On the previous day, the industrial silicon market price was weakly stable. The supply side remained stable for the time being, and some manufacturers intended to cut production. The price of East China oxygen - passing 553 silicon was 9,500 - 9,800 yuan/ton, and that of East China 421 silicon was 10,200 - 10,600 yuan/ton. The closing price of the main contract Si2506 of industrial silicon futures was 8,800, down 0.73%, with a reduction of 5,009 lots. The current position was 188,100 lots, and the trading volume was 7.78 billion yuan [1]. Supply Side - Some manufacturers intended to conduct maintenance, and the overall supply might decline. The industrial silicon operation in Gansu production area was relatively stable. The price of 97 silicon had fallen below 9,000 yuan/ton, and the operation rate was at a low level. The current quotation of medium - frequency furnace 3303 silicon was 10,100 - 10,200 yuan/ton, and some medium - frequency furnaces were waiting and watching, with difficult short - term improvement in operation [1]. Demand Side - The price of polysilicon declined. Under the retreat of demand, components started to compete at low prices for shipment, intensifying the negative feedback in the industrial chain. The price pressure in each link was gradually transmitted upwards. Under the pressure of lower - than - expected demand and high inventory, the silicon material production cut increased, and the quotation was also lowered. The current quotation of re - feeding material was 36 - 38 yuan/kg, that of dense material was 34 - 37 yuan/kg, that of cauliflower material was 31 - 33 yuan/kg, and that of N - type material was 39 - 41 yuan/kg. The price of organic silicon DMC showed a fluctuating trend, with the market's mainstream opening price referring to 11,300 - 13,000 yuan/ton (net water delivered). Near the holiday, the rigid demand procurement of downstream enterprises was gradually released, the market inquiry activity increased, and the spot transaction showed a warming trend compared with the previous period. However, industry players were not very optimistic about the future market, and it was expected that the organic silicon market would remain weakly stable in the short term. The price of aluminum alloy ingots was weak. The spot market still showed a situation of weak supply and demand, the downstream demand was difficult to improve, both buyers and sellers were mainly waiting and watching cautiously, and the trading volume was low [1]. Inventory - On April 28, the warehouse receipt inventory of industrial silicon was 69,417 lots, with a single - day decrease of 85 lots. The warehouse receipt inventory was still at a high level [1].

Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The current absolute price of industrial silicon has reached a historical low, but due to weak end - market demand and high inventory, the industrial silicon market will remain weak in the short term [2]. 3. Key Points from Different Aspects Market Price - This week, the industrial silicon market showed a downward trend in both spot and futures prices. The price of East China oxygen - fed 553 silicon is 9,500 - 9,900 yuan/ton, and that of East China 421 silicon is 10,200 - 10,600 yuan/ton. On Friday, the closing price of the main industrial silicon futures contract si2506 was 8,780 yuan, down 0.85%, with an increase of 10,449 lots in positions, the current open interest was 193,100 lots, and the trading volume was 8.356 billion yuan [1]. Supply - In the supply side, small factories in the north have increased their production cut - back efforts, mostly with 12,500KVA furnaces. However, the gradual start - up in the south has offset some of the production reduction, resulting in limited week - on - week fluctuations in weekly supply. The start - up in the southern production areas is slowly recovering, but some small and medium - sized manufacturers still lack confidence in resuming production and are mostly in a wait - and - see mode. In the short term, the supply is still concentrated in the north. A large northern factory plans to conduct maintenance soon, and the production cut situation is unclear. Despite the current low - level start - up, there is still an expectation of increased national production during the wet season [1]. Demand - For the downstream polysilicon plants, the powder single - tender prices released this week decreased by about 500 - 700 yuan/ton compared with the previous period. The supply of silicon material enterprises decreased slightly this week, but with the decline in terminal installation demand, the prices of components and cells dropped rapidly, and market expectations weakened significantly. The price of organic silicon DMC showed a fluctuating downward trend, with the mainstream opening price at 11,500 - 13,000 yuan/ton (net water delivered). The growth rate of new capacity of organic silicon monomers has slowed down significantly, and monomer plants have taken turns to cut production. The aluminum alloy ingot price is weak, and the spot market shows weak supply and demand, with low trading volume [1]. Inventory - On April 25, the industrial silicon warehouse receipt inventory was 69,502 lots, a decrease of 859 lots in a single week, but the warehouse receipt inventory is still at a high level [1].
