Core Viewpoint - The industrial silicon market is experiencing price fluctuations with current prices hovering at the bottom, indicating a price negotiation phase. The supply side shows stable production but with downward price pressure, while demand remains steady with signs of improvement in downstream sectors [1] Supply Side - The current ex-factory prices for industrial silicon in East China are 8900 - 9200 CNY/ton for 553 silicon and 9800 - 10100 CNY/ton for 421 silicon [1] - The main futures contract for industrial silicon (si2506) closed at 8490 CNY, up 2.72%, with a decrease in open interest by 15,774 contracts, totaling 146,500 contracts and a transaction value of 16.036 billion CNY [1] - Production remains stable in Inner Mongolia, Ningxia, Shaanxi, and Shandong, but the sentiment among silicon manufacturers is low due to price pressures, with some production in Yunnan being planned [1] Demand Side - The prices for multi-crystalline silicon are stable, with N-type dense material priced at 38 - 40 CNY/kg, N-type granular silicon at 35 - 38 CNY/kg, N-type recycled material at 39 - 43 CNY/kg, and N-type mixed package material at 36 - 38 CNY/kg [1] - The silicon material market is characterized by a strong price support mentality from silicon manufacturers, despite ongoing price declines in downstream sectors [1] - The price of DMC (Dimethyl Carbonate) is stable, with mainstream opening prices ranging from 11,300 - 12,000 CNY/ton, while major manufacturers continue to negotiate prices aggressively [1] Inventory and Market Outlook - As of May 14, the industrial silicon warehouse inventory stands at 66,531 contracts, an increase of 31 contracts, indicating a high overall inventory level [1] - The current oversupply situation in the industrial silicon market is unlikely to change in the short term, but there are signs of improvement in downstream stability, suggesting a gradual bottoming out of silicon prices [1] - Future attention should be paid to macro policies, production conditions of leading companies, and policies in the photovoltaic industry [1]

Group 1 - Report industry investment rating: Not provided Group 2 - The core view of the report: The current oversupply pattern of industrial silicon is difficult to change in the short term, but there are signs of improvement in the downstream, and the silicon price is approaching the bottom [3] Group 3 Market Conditions - Industrial silicon spot prices fluctuated little yesterday, with the ex - factory price hovering at the bottom. The price of East China oxygen - passing 553 silicon is 8900 - 9200 yuan/ton, and that of East China 421 silicon is 9800 - 10100 yuan/ton [2] - The closing price of the main contract si2506 of industrial silicon futures yesterday was 8490, up 2.72%, with a single - day reduction of 15774 lots. The current position is 146,500 lots, and the trading volume is 16.036 billion yuan [2] Supply Side - Silicon enterprises in Inner Mongolia, Ningxia, Shaanxi, and Shandong have stable production starts. Under the pressure of falling prices, the enthusiasm of silicon factories to start production is not high. Some silicon enterprises in Yunnan are planning to start production. The ex - factory quotation of silicon enterprises is slightly higher than the futures price, but there is not enough risk - free arbitrage and hedging space. Traders and basis traders are cautious in purchasing, and the overall inventory remains at a high level [2] Demand Side - Polysilicon prices are temporarily stable. N - type dense material is quoted at 38 - 40 yuan/kg, N - type granular silicon at 35 - 38 yuan/kg, N - type re -投料 at 39 - 43 yuan/kg, and N - type mixed material at 36 - 38 yuan/kg. Silicon material enterprises have a strong mentality of maintaining prices, and the prices are temporarily stable [2] - The price of organic silicon DMC is stable. The market's mainstream opening price is 11300 - 12000 yuan/ton (net water delivered). Large monomer manufacturers still offer discounts in actual transactions and have a strong willingness to ship. The number of inquiries from downstream enterprises has increased, showing a certain purchasing intention [2] - The price of aluminum alloy ingots is improving. Enterprises are producing normally and actively shipping. Favorable macro news has improved the market trading atmosphere [2] Inventory - On May 14, the warehouse receipt inventory of industrial silicon was 66,531 lots, an increase of 31 lots, and the total inventory of industrial silicon remains at a high level [2]

Report Industry Investment Rating - Not provided Core Viewpoint of the Report - The current oversupply situation of industrial silicon is difficult to change in the short term. Downstream production cuts and high inventory suppress price rebounds, leading to weak and volatile silicon prices [2] Summary by Relevant Catalogs Market Conditions - Yesterday, the industrial silicon market declined. Manufacturers' quotes were under pressure, and downstream demand had no new growth. The price of East China oxygenated 553 silicon was 8900 - 9200 yuan/ton, and that of East China 421 silicon was 9800 - 10100 yuan/ton. The closing price of the industrial silicon futures main contract si2506 was 8230, down 0.60%, with a single - day reduction of 9326 lots. It was shifting to the far - month contract, with a current position of 162,300 lots and a trading volume of 13.666 billion yuan [1] Supply Side - Recently, some silicon plants in the South are preparing to start furnaces, and some submerged arc furnaces will start from the end of this month to early next month. Some northern factories are struggling at the cost line. If the futures price drops below 8000, some small and medium - sized silicon plants are expected to cut production [1] Demand Side - Polysilicon prices are stable, with continuous news of production cuts and acquisitions. The current quotes for N - type dense material, N - type granular silicon, N - type re - feeding material, and N - type mixed material are 38 - 40 yuan/kg, 35 - 38 yuan/kg, 39 - 43 yuan/kg, and 36 - 38 yuan/kg respectively. The price of organic silicon DMC is stable, with a market - mainstream opening price reference of 11300 - 12000 yuan/ton (net water delivered). Shandong's main monomer enterprises slightly lowered prices to boost sales, but downstream inquiry enthusiasm was low, and procurement was mainly for rigid demand. The overall demand release was limited, and market transactions weakened with strong bargaining tendencies. Aluminum alloy ingot prices were temporarily stable, the industry's operating rate decreased, and downstream enterprises mainly consumed pre - holiday orders with insufficient post - holiday stocking willingness [1] Inventory - On May 13th, the industrial silicon warehouse receipt inventory was 66,494 lots, a decrease of 603 lots. Although the warehouse receipt inventory continued to decrease, the total industrial silicon inventory remained at a high level [1]
