多晶硅周报：下周会议或有新的产能整合或出清动向，多晶硅有望偏强震荡-20250811

1. Report Industry Investment Rating - The report gives a bullish outlook on polysilicon, suggesting it is likely to experience strong fluctuations. It recommends a strategy of buying on dips, with a focus on the polysilicon futures market [3][5]. 2. Core Viewpoints of the Report - In August, both supply and demand of polysilicon are increasing, but the supply growth rate is higher, leading to inventory accumulation pressure. If there are new developments in capacity integration or exit, polysilicon prices may rise again; otherwise, they may fluctuate downward under inventory and warrant pressure [3][5]. - The anti - involution policy has supported the increase in polysilicon prices, and the industry is expected to shift from "scale expansion" to "quality development." The sustainability of price increases and their downstream transmission are key factors, and capacity integration and output regulation are important for the industry's sustainable development [30][31]. 3. Summary According to the Table of Contents 3.1 Periodic and Spot Price Trends - Spot Price Trend Review: Guided by the anti - involution policy, polysilicon prices remained stable, with an average price of about 47,200 yuan/ton. The average prices of various types of polysilicon, such as N - type recompounded materials, were stable, and the transaction prices showed a slight increase [7][8]. - Spot Trend Analysis: The price difference between PS2511 and PS2512 contracts is large, mainly because the warrants of the 11 - contract will be centrally cancelled upon expiration [9]. - Futures Contract Price Trend: The price of the main contract PS2511 increased by 3.23% to 50,790 yuan/ton [3][5]. 3.2 Supply and Demand Analysis - Supply Side: In August, polysilicon production is expected to reach 125,000 - 130,000 tons, with the weekly output increasing by 11% to 29,400 tons. There are 9 polysilicon enterprises in production this week, with one resuming production and another entering maintenance. The proportion of N - type polysilicon and granular silicon is increasing, and the industry is expected to see capacity integration and exit [18][19][21]. - Demand Side: Downstream product prices, such as silicon wafers, battery cells, and components, have increased to varying degrees, and demand has slightly recovered. Overseas demand may also increase. The weekly output of silicon wafers increased by 1.02GW to 12.02GW, an increase of about 9%. The output of battery cells and components in August is expected to increase slightly [5][32][49]. - Supply - Demand Balance: There is an oversupply situation, and inventory is expected to accumulate. The weekly output of polysilicon increased by 11%, while the weekly output of silicon wafers increased by 9%, slightly lower than the growth rate of polysilicon [5]. 3.3 Cost and Profit - The cost of polysilicon may increase due to the rise in raw material prices such as coal and industrial silicon. The increase in polysilicon prices is beneficial for profit repair in the photovoltaic industry, but the cost pressure will be transmitted to terminal installation enterprises. The acceptance of price increases by downstream power stations needs attention [68]. 3.4 Import and Export - The report provides data on China's polysilicon, monocrystalline silicon wafer, polycrystalline silicon wafer, battery cell, and component import and export volumes, but no specific analysis of trends is provided [71][81][97]. 3.5 Inventory - This week, polysilicon inventory increased by 0.4 tons to 233,000 tons, and warrants increased by 380 lots to 3,580 lots, equivalent to 10,740 tons. As prices rise above full cost, warrants are expected to further increase [5][105][106].
