Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - The current supply and demand of industrial silicon and polysilicon are both weak, with slow inventory depletion for industrial silicon and high inventory levels for polysilicon. Industrial silicon is expected to maintain wide - range fluctuations in the short term, while polysilicon is expected to remain in high - level oscillations, supported by anti - involution policies and market expectations. Attention should be paid to the start - up changes of large northwest factories and the implementation of policies [6][8]. 3. Summary by Related Catalogs Industrial Silicon - **Price**: The spot price of industrial silicon fluctuated significantly this week. As of November 21, 2025, the price of Xinjiang industrial silicon 553 oxygen - passed was 8900 yuan/ton, unchanged from last week. The futures main contract showed a weak oscillation, then a sharp rise and fall, and closed at 8960 yuan/ton on November 21 [6]. - **Supply**: Xinjiang's start - up rate remained stable, with stable supply. There were few changes in the start - up in Qinghai, Ningxia, and Gansu in the Northwest. Some silicon enterprises in Yunnan reduced or stopped production, with a slight decline in output. Sichuan is in the flat - water period and will enter the dry - water period at the end of the month, with a further decline in the start - up rate. Overall, industrial silicon production decreased month - on - month [6]. - **Demand**: The weekly start - up of polysilicon enterprises remained stable, with relatively stable demand for industrial silicon. The start - up of organic silicon was basically stable, with a small increase in monomer production capacity recently. After the organic silicon anti - involution meeting, the price increased, but then fell. The start - up rate of aluminum alloy enterprises increased slightly, with good downstream order demand. In October, industrial silicon exports were 45,100 tons, a 36% month - on - month and 31% year - on - year decrease [6]. - **Cost**: The cost of industrial silicon remained stable this week [6]. - **Inventory**: As of November 20, the national social inventory of industrial silicon was 548,000 tons, an increase of 2000 tons from last week [6]. - **Price Difference**: As of November 21, 2025, the price difference between Yunnan industrial silicon 553 oxygen - passed and 421 oxygen - passed was 400 yuan/ton, unchanged from last week.

The futures main contract fluctuated sharply at a high level and closed at 53,360 yuan/ton on November 21 [8]. - **Supply**: In November, with the shutdown of a large number of production capacities in Sichuan and Yunnan during the dry - water period, the polysilicon output is expected to be close to 120,000 tons, a significant decrease from October. The output is expected to continue to decline in December [8]. - **Demand**: The current terminal demand is weak. The terminal component prices are weakly stable, while the prices of silicon wafers and battery cells continue to fall. Downstream crystal - pulling enterprises have a low willingness to purchase and only maintain rigid restocking. In October, the polysilicon import volume was 1446.4 tons, a 12% month - on - month increase; in September, the polysilicon export volume was 1547.9 tons, a 28% month - on - month decrease [8]. - **Cost**: The cost of polysilicon remained stable this week [8]. - **Inventory**: As of November 21, the polysilicon factory inventory was 268,500 tons, an increase of 2800 tons from last week [8].

Group 1: Report Industry Investment Rating - No relevant content Group 2: Core View of the Report - The short - term disk of lithium carbonate fluctuates greatly, but the spot transaction has improved. Supply has shrunk, consumption has increased month - on - month, and there is also uncertainty in other lithium ore supplies. The subsequent start - up situation of the ore end needs attention. The lithium ore approval issue remains uncertain, and the recent market may still fluctuate [1][3] Group 3: Summary According to Related Catalogs Market Analysis - On August 13, 2025, the lithium carbonate main contract 2511 opened at 83,000 yuan/ton and closed at 85,100 yuan/ton, with a - 0.61% change in the closing price compared to the previous settlement price. The trading volume was 1,245,424 lots, and the open interest was 392,675 lots. The previous day's open interest was 356,998 lots. The current basis was - 3,360 yuan/ton. The lithium carbonate warehouse receipts were 21,679 lots, an increase of 850 lots from the previous trading day [2] - According to SMM data, the price of battery - grade lithium carbonate was 79,000 - 83,000 yuan/ton, an increase of 3,000 yuan/ton from the previous trading day. The price of industrial - grade lithium carbonate was 78,100 - 79,500 yuan/ton, also an increase of 3,000 yuan/ton. The price of 6% lithium concentrate was 970 US dollars/ton, an increase of 30 US dollars/ton. Due to the rigid demand of some downstream enterprises and the reluctance of upstream and traders to sell, the transaction price of lithium carbonate spot has continued to rise significantly [2] Strategy - Supply has shrunk, consumption has increased month - on - month, and there is uncertainty in other lithium ore supplies. Attention should be paid to the subsequent start - up of the ore end. The lithium ore approval issue remains uncertain, and the recent market may fluctuate. Participants need to manage risks [3] Hedging Strategy - Unilateral: Buy on dips for hedging; No strategies for inter - period, cross - variety, spot - futures, and options [5]
