Report Industry Investment Rating No relevant content provided. Core Views - The industrial silicon futures and spot prices are in a downward trend. The supply in the northwest region remains relatively high, and the demand is weak. The industry is expected to oscillate weakly in the short term [1][2][3]. - The polysilicon futures price hit a new low, while the spot price remained stable. There is a game between production cuts by polysilicon enterprises to support prices and weak demand. The 2506 contract may rebound due to delivery games [4][6][7]. Summary by Related Catalogs Industrial Silicon Market Analysis - On May 7, 2025, the industrial silicon futures price hit a new low. The main contract 2506 opened at 8420 yuan/ton and closed at 8290 yuan/ton, down 0.96% from the previous settlement. The open interest of the 2505 main contract was 182,782 lots, and the number of warehouse receipts on May 8 was 68,686 lots, a decrease of 244 lots from the previous day [1]. - The spot price of industrial silicon declined. The price of oxygenated 553 silicon in East China was 9100 - 9300 yuan/ton, down 100 yuan/ton; the price of 421 silicon was 9900 - 10300 yuan/ton, down 100 yuan/ton [1]. - The consumption of organic silicon DMC was stable, with a quotation of 11300 - 11800 yuan/ton. The overall operating capacity of domestic monomers decreased due to the resumption of some plants in East and North China and the maintenance of an 800,000 - ton plant in the northwest [1]. Strategy - The industry's total inventory pressure is relatively high, and the short - term oversupply situation is difficult to change. Industrial silicon is expected to oscillate weakly. For the unilateral strategy, it is advisable to operate within a range, and upstream enterprises can sell hedging at high prices [3]. Polysilicon Market Analysis - On May 7, 2025, the main contract 2506 of polysilicon futures continued to decline, opening at 36,670 yuan/ton and closing at 35,520 yuan/ton, a decrease of 3.14% from the previous trading day. The open interest of the main contract reached 63,290 lots, and the trading volume was 135,166 lots [4]. - The spot price of polysilicon remained stable. The price of polysilicon re - feedstock was 35.00 - 36.00 yuan/kg; the price of dense polysilicon was 34.00 - 35.00 yuan/kg [4]. - Polysilicon factory inventory decreased, while silicon wafer inventory increased. The polysilicon inventory was 26.10 (with a month - on - month change of - 0.50%), and the silicon wafer inventory was 20.62GW (with a month - on - month change of 5.58%). The weekly polysilicon output was 22,400 tons, a month - on - month decrease of 1.75%, and the silicon wafer output was 13.29GW, a month - on - month decrease of 0.67% [5]. - The prices of silicon wafers, battery cells, and components remained stable [5]. - In May, the polysilicon output decreased by about 0.2 million tons month - on - month, and the silicon wafer output decreased by about 4GW month - on - month. Some enterprises have new production capacity investment expectations in May, and the registration of warehouse receipts has started [6]. Strategy - The 2506 contract may rebound due to delivery games. Investors can choose to build long positions opportunistically. If the rebound is significant, upstream enterprises can sell hedging [7].

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]

Core Viewpoint - The price of polysilicon remains stable this week, with specific price ranges and average prices for different types of polysilicon being reported. The overall market dynamics indicate a low transaction volume and high inventory levels among downstream enterprises, affecting price transmission in the supply chain [1]. Price Trends - The transaction price range for n-type polysilicon is between 39,000-46,000 CNY/ton, with an average price of 41,700 CNY/ton. The n-type granular silicon has a transaction price range of 38,000-41,000 CNY/ton, with an average price of 39,000 CNY/ton. The p-type polysilicon has a transaction price range of 32,000-36,000 CNY/ton, with an average price of 34,000 CNY/ton [1]. Market Dynamics - A few polysilicon companies have completed their orders for the month, while others still have room for signing contracts. The number of companies that have transacted n-type polysilicon this week is seven. Feedback from enterprises indicates that the transaction volume is at a low level, with downstream companies maintaining high raw material inventory and only engaging in essential purchases [1]. Inventory and Production - The high inventory levels and low purchasing frequency among downstream enterprises significantly impact the smooth transmission of prices in the supply chain, resulting in the continued low and stable operation of polysilicon prices during this round of installations. As of now, all operating polysilicon companies in China are basically running at reduced capacity, and the expected maintenance plans for this month have been postponed, with no companies undergoing maintenance during the month [1]. Future Outlook - According to the production plans for April, an overall increase in demand is expected, and the polysilicon sector is likely to maintain a slight destocking trend. With the upcoming warehouse receipt registration in April, some companies have begun to actively increase the proportion of dense material products, which may lead to clearer demand from traders and futures merchants, potentially creating a new growth point [1].
