有色金属周报：工业硅、多晶硅关注供给端政策-20251015

1. Report Industry Investment Rating No relevant information provided. 2. Core Viewpoints of the Report - The industrial silicon market maintains a pattern of strong supply and weak demand, with the short - term expected to trade in the range of 8,300 - 9,000 yuan/ton. Continued attention should be paid to macro - sentiment fluctuations and supply - side start - up conditions [3]. - The polysilicon market is in a state of high - level range - bound trading due to the game between policy - favorable expectations and weak fundamentals. Continued attention should be paid to the implementation of industrial policies and macro - sentiment [3]. 3. Summary According to the Directory 3.1产业链价格回顾 - Industrial Silicon Futures and Spot Prices: On October 10, 2025, the closing price of the industrial silicon futures main contract was 8,685 yuan/ton, up 0.52% from September 30. Most spot prices remained unchanged, with only the price of the oxygen - free 553 at Tianjin Port down 0.53% [12]. - Polysilicon Futures and Spot Prices: The closing price of the polysilicon futures main contract on October 10, 2025, was 48,965 yuan/ton, down 4.66% from September 30. Spot prices of various polysilicon types remained unchanged [12]. - Silicon Wafer, Battery Cell, and Component Prices: Prices of silicon wafers, battery cells, and components were generally stable, with only minor price changes in some products [12]. - Organic Silicon and Aluminum Alloy Prices: As of October 10, the average DMC price was 11,050 yuan/ton, unchanged from the previous period; the 107 - rubber average price was 11,500 yuan/ton, up 3.14% from the previous period; the silicone oil average price was 12,850 yuan/ton, unchanged from the previous period. The ADC12 average price was 21,100 yuan/ton, up 0.96% from the previous period; the A356 average price was 21,450 yuan/ton, up 1.42% from the previous period [12]. 3.2开炉增加，供给持续增量 - Cost and Profit of Industrial Silicon: Driven by anti - involution sentiment and increased demand, the prices of silicon coal, petroleum coke, and electrodes have rebounded. The power cost in the southwest production area will gradually increase as it transitions from the wet season to the dry season [3]. - Supply of Industrial Silicon: In October, Sichuan and Yunnan are transitioning to the dry season, leading to increased costs and production cuts by some enterprises. In contrast, small factories in Gansu and Ningxia have completed raw material stockpiling, and the start - up rate in Xinjiang has increased. Overall, the start - up rate has increased [3]. - Demand for Industrial Silicon: The production of polysilicon in October may still have a slight increase, increasing the demand for industrial silicon. However, some organic silicon enterprises have maintenance plans, and the start - up rate has declined. Overall, the demand for industrial silicon remains weak [3]. - Inventory of Industrial Silicon: The futures warehouse receipts have fluctuated slightly. After the holiday, downstream enterprises have successively inquired, but some manufacturers' orders have not been delivered, and factory inventories have accumulated [3]. 3.3光伏产业运行平稳，关注终端需求 - Polysilicon: In September, the polysilicon output was 130,000 tons, basically the same as in August. The cumulative output from January to September was 941,600 tons, a cumulative year - on - year decrease of 33%. It is expected that the output in October will maintain an incremental trend, with a month - on - month increase of about 3,000 - 5,000 tons. As of October 9, the total polysilicon inventory was 240,000 tons, and the silicon wafer inventory was 16.78 GW. As of October 10, the registered polysilicon warehouse receipts were 8,140 lots [3]. - Silicon Wafer: The market was sluggish during the holiday, with little market trading [80]. - Battery Cell: The price was stable [87]. - Component: The component installation did not meet expectations, and the price was under pressure. The lifting of the component export tax - refund policy is still undetermined. If the policy is implemented, it may stimulate component export demand in the next few months. The pre - implementation inventory rush of India's "double - anti" policy will also support exports to some extent. Domestically, the front - loaded installation in the first half of the year has overdrawn some demand in the second half, resulting in a decrease in domestic tender and bidding projects, lower - than - expected centralized installation, and a decline in distributed trading volume. The component segment is under great pressure, and there is no obvious restocking action for upstream demand [3]. 3.4支撑有限，有机硅价格大稳小动 - Start - up Rate: In September, the start - up rate of China's DMC was 71.25%, a month - on - month decrease of 4.38 percentage points. The DMC output was 210,200 tons, a month - on - month decrease of 12,900 tons. Recently, a monomer factory has a maintenance plan, and the start - up rate may decline slightly [108]. - Price: As of October 10, the average DMC price was 11,050 yuan/ton, unchanged from the previous period; the 107 - rubber average price was 11,500 yuan/ton, up 3.14% from the previous period; the silicone oil average price was 12,850 yuan/ton, unchanged from the previous period. Due to factory maintenance, the supply has tightened periodically, and the price has increased [114]. 3.5铝合金开工回升 - Start - up Rate: In the week of October 9, the start - up rate of primary aluminum alloy was 58%, a month - on - month decrease of 0.4 percentage points; the start - up rate of recycled aluminum alloy was 58.9%, a month - on - month increase of 2.3 percentage points [122]. - Price: As of October 10, the average ADC12 price was 21,100 yuan/ton, up 0.96% from the previous period; the average A356 price was 21,450 yuan/ton, up 1.42% from the previous period [125]. 3.6库存维持高位 - Industrial Silicon Inventory: As of October 9, the social inventory of industrial silicon (social inventory + delivery warehouse) was 545,000 tons, a month - on - month increase of 2,000 tons; the total factory inventory in Xinjiang, Yunnan, and Sichuan was 167,900 tons, a month - on - month increase of 54,000 tons. As of October 10, the exchange - registered warehouse receipts were 50,281 lots, equivalent to 251,400 tons of spot [139]. - Polysilicon Inventory: As of October 9, the total polysilicon inventory was 240,000 tons, an increase of 14,000 tons [74].
