Group 1: Research View - On August 12, industrial silicon fluctuated weakly. The main contract 2511 closed at 8,840 yuan/ton, with an intraday decline of 1.12%. The position increased by 6,917 lots to 279,000 lots. The spot reference price of industrial silicon by Baichuan was 9,540 yuan/ton, remaining stable compared to the previous trading day. The price of the lowest deliverable 421 grade rebounded to 8,950 yuan/ton, and the spot premium widened to 150 yuan/ton [2]. - Polysilicon fluctuated strongly. The main contract 2511 closed at 51,800 yuan/ton, with an intraday increase of 0.69%. The position decreased by 3,684 lots to 136,000 lots. The price of N-type recycled polysilicon materials dropped to 44,500 yuan/ton, and the price of the lowest deliverable silicon materials also dropped to 44,500 yuan/ton. The spot discount narrowed to 6,005 yuan/ton [2]. - The north and south of industrial silicon continued to resume production, and the downstream crystalline silicon production increased significantly. The supply and demand showed a double - increase pattern, and it will continue to fluctuate following the sentiment of coking coal in the short term. Recently, industrial silicon industry associations in many provinces put forward a joint initiative against involution. In the short term, relevant news may become an important driver for the industrial silicon futures market [2]. - After the polysilicon futures market showed a premium again, it attracted an increase in warehouse receipts. The market traded on a series of news such as capacity storage. In the short term, the range pattern of polysilicon with a clear upper and lower limit is relatively obvious. Attention should be paid to the resumption progress of industrial silicon production, the impact of the association's initiative, and the policy promotion of polysilicon [2]. Group 2: Daily Data Monitoring Industrial Silicon - The futures settlement price of the main contract decreased from 8,940 yuan/ton on August 11 to 8,905 yuan/ton on August 12, a decrease of 35 yuan/ton. The near - month contract decreased from 8,860 yuan/ton to 8,800 yuan/ton, a decrease of 60 yuan/ton [4]. - The spot prices of most grades of industrial silicon remained stable, except for some minor price increases in the 421 grade in certain regions. The current lowest deliverable price was 8,950 yuan/ton, and the spot premium widened from 90 yuan/ton to 150 yuan/ton [4]. - The industrial silicon warehouse receipts decreased by 102 to 50,658 (daily), and the Guangzhou Futures Exchange inventory decreased by 880 to 251,700 tons (weekly). The total social inventory of industrial silicon increased by 4,100 tons to 444,000 tons [4].
