硅料挺价氛围浓厚，工业硅震荡走强

1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core View of the Report - Last week, industrial silicon showed a strong and volatile trend, mainly due to the strong price - holding atmosphere in each link of the photovoltaic industry chain. The polysilicon market had a lot of "rumors", but market transactions were relatively limited, and the anti - involution sentiment continued to ferment. It is expected that the futures price will maintain a volatile and strong operation in the short term [2][3][6]. 3. Summary According to Relevant Catalogs 3.1 Market Data | Contract | 8/15 Price | 8/8 Price | Change | Change Rate | Unit | | --- | --- | --- | --- | --- | --- | | Industrial silicon main contract | 8805.00 | 8710.00 | 95.00 | 1.09% | Yuan/ton | | Oxygen - passing 553 spot | 9400.00 | 9250.00 | 150.00 | 1.62% | Yuan/ton | | Non - oxygen - passing 553 spot | 9200.00 | 9100.00 | 100.00 | 1.10% | Yuan/ton | | 421 spot | 9750.00 | 9700.00 | 50.00 | 0.52% | Yuan/ton | | 3303 spot | 9600.00 | 9500.00 | 100.00 | 1.05% | Yuan/ton | | Silicone DMC spot | 11400.00 | 12150.00 | - 750.00 | - 6.17% | Yuan/ton | | Polysilicon dense material spot | 46.00 | 44.00 | 2.00 | 4.55% | Yuan/ton | | Industrial silicon social inventory | 54.5 | 54.7 | - 0.2 | - 0.37% | 10,000 tons | [4] 3.2 Market Analysis and Outlook - Supply side: The operating rate in Xinjiang rose to 57%, and the operating rates in Sichuan and Yunnan increased month - on - month, showing a marginally loose supply situation. As of August 14, the weekly output of industrial silicon was 84,700 tons, a month - on - month increase of 1.5% and a year - on - year decrease of 16.3%. The number of open furnaces in the three major production areas remained at 280, and the overall open - furnace rate slightly rose to 35.2% [6][7][8]. - Demand side: Polysilicon enterprises had a strong price - holding atmosphere, but transactions were limited near the end of the signing period. The inventory in the silicon wafer market decreased significantly, and most integrated enterprises tended to reduce production. Photovoltaic cell manufacturers mainly executed existing orders, and there might be resistance to the increase in domestic export orders. The component end showed a weak and volatile trend, and terminal demand was poor [2][6][8]. - Inventory: As of August 15, the national social inventory of industrial silicon decreased to 545,000 tons, a month - on - month decrease of 2,000 tons. The warehouse receipt inventory of the Guangzhou Futures Exchange continued to rise to 50,599 lots, equivalent to 253,000 tons [9]. 3.3 Industry News - The automotive and photovoltaic industries held symposiums against disorderly competition. In 2024, the production capacity of Chinese chip manufacturers increased by 15%. In 2025, domestic wafer foundries will be the main force in the increase of mature - process production capacity, but price trends will be suppressed. Some enterprises are exploring ways to break through the low - level competition dilemma, such as Ruixin Micro focusing on basic capabilities and high - end markets [11]. - In the second half of 2025, the DDR4 market was in short supply, and prices rose strongly. The tight supply and demand in the DDR market also pushed up the contract price of Mobile DRAM. The third - quarter increase in LPDDR4X was the largest in a single quarter in the past decade. The demand for semiconductor hardware was growing steadily, and the storage sector was expected to continue to rise in the third and fourth quarters [12]. 3.4 Relevant Charts - The report provides 10 charts, including those related to industrial silicon production, export volume, social inventory, warehouse receipt inventory, production in major production areas, and prices of various products such as organic silicon DMC, polysilicon, and industrial silicon [15][18].
