有色金属周报：工业硅、多晶硅上方承压-20251111

1. Report Industry Investment Rating No relevant information provided. 2. Core Views of the Report - Industrial silicon supply is tightening, with demand mainly for rigid procurement. The oversupply situation remains unchanged, and weak demand and high inventory are the main factors restricting price increases. Short - term silicon prices are expected to range between 8,500 - 9,500 yuan/ton [3]. - The "purchase and storage platform" for polysilicon has not been implemented, and the market has become desensitized. With weak demand and high inventory risks, polysilicon spot prices have declined, and the high premium in the futures market lacks support. Short - term prices are expected to consolidate, and previous long positions should protect profits [3]. 3. Summary by Directory 3.1 Industrial Silicon 3.1.1 Cost and Profit - Petroleum coke prices have slightly increased, while silica, electrode prices have remained stable. With the southwest region entering the dry - season, power costs have significantly increased [3]. - In September, the average profit of industrial silicon 553 was - 1,029 yuan/ton, a month - on - month increase of 252 yuan/ton; the average profit of 421 was - 665 yuan/ton, a month - on - month increase of 267 yuan/ton [36]. 3.1.2 Supply - In Sichuan, as it enters the normal - water period and electricity prices rise, most manufacturers have stopped production. In Yunnan, due to the dry - season and increased costs, most businesses have stopped production. In the north, the start - up rate is slowly increasing, but a factory in Xinjiang reduced production last week. The overall supply is expected to fall below 400,000 tons in November, a decrease of about 12% [3]. - On November 7, the number of open furnaces decreased by 37 week - on - week, mainly in Sichuan and Yunnan, and slightly in Xinjiang [37]. 3.1.3 Demand - Some polysilicon manufacturers are under maintenance, and production is expected to decline. Organic silicon enterprises that previously cut production have gradually resumed, increasing the demand for industrial silicon, but purchases are mainly for rigid replenishment. The silicon - aluminum alloy industry has no plans to increase or decrease production, and the start - up rate is relatively stable [3]. 3.1.4 Inventory - Except for some southwest silicon enterprises that have reduced production, most manufacturers are in normal production. Due to low prices, silicon enterprises are reluctant to sell, and inventory continues to accumulate [3]. 3.1.5 Market Outlook - The oversupply situation of industrial silicon remains unchanged. Weak demand and high inventory restrict price increases. Short - term silicon prices are expected to range between 8,500 - 9,500 yuan/ton [3]. 3.2 Polysilicon 3.2.1 Supply - Last week, polysilicon production was 27,000 tons, a week - on - week decrease of 1,200 tons. As of November 6, the inventory was 259,000 tons, a decrease of 2,000 tons. In October, production was 134,000 tons, an increase of 4,000 tons from September. In November, production is expected to decline to about 120,000 tons [68]. 3.2.2 Demand - The upstream demand from the component side is weak, and there is no obvious inventory - building action. The support from the battery - chip side is insufficient, and the silicon - wafer production plan for November has declined [3]. 3.2.3 Inventory - As of November 6, the total polysilicon inventory was 259,000 tons, and the silicon - wafer inventory was 17.52GW. As of November 7, the registered polysilicon warehouse receipts were 9,850 lots [3]. 3.2.4 Market Outlook - The "purchase and storage platform" has not been implemented, and the market has become desensitized. With weak demand and high inventory risks, polysilicon spot prices have declined, and the high premium in the futures market lacks support. Short - term prices are expected to consolidate [3]. 3.3 Organic Silicon 3.3.1 Supply - In October, the DMC start - up rate was 69.71%, a month - on - month decrease of 1.54 percentage points, and the output was 209,600 tons, a month - on - month decrease of 600 tons. Recently, the previously maintained devices in Yunnan and Jiangxi have gradually resumed production, and the supply shows an increasing trend [97]. 3.3.2 Price - As of November 7, the average DMC price was 11,150 yuan/ton, a week - on - week increase of 1.36%; the average 107 - rubber price was 11,500 yuan/ton, remaining unchanged; the average silicone oil price was 13,050 yuan/ton, a week - on - week increase of 1.56%. In the long - term, prices may continue to weaken due to oversupply [104]. 3.4 Aluminum Alloy 3.4.1 Start - up Rate - In the week of November 6, the start - up rate of primary aluminum alloy was 59.4%, a week - on - week increase of 0.2 percentage points; the start - up rate of recycled aluminum alloy was 59.1%, remaining unchanged [112]. 3.4.2 Price - As of November 7, the average ADC12 price was 21,450 yuan/ton, a week - on - week increase of 0.70%; the average A356 price was 22,000 yuan/ton, a week - on - week increase of 1.38% [115]. 3.5 Inventory - As of November 6, the industrial silicon social inventory (social + delivery warehouse) was 552,000 tons, a week - on - week decrease of 6,000 tons; the total factory inventory in Xinjiang, Yunnan, and Sichuan was 172,000 tons, a week - on - week increase of 3,900 tons. As of November 7, the exchange - registered warehouse receipts were 46,180 lots, equivalent to 230,900 tons of spot [126].
