近期，工业硅期货维持震荡下跌态势。9月30日，工业硅期货主力2511合约收报8640元/吨，下跌 0.17%，重回9000元/吨下方。 中信期货分析师郑非凡认为，当前工业硅期货价格震荡下行，主要原因是成本支撑减弱。"此前，煤炭 价格上涨为工业硅价格带来有力的成本支撑，叠加西北产区复产节奏放缓限制了供应增长。临近国庆假 期，煤炭市场交易量减少，价格大幅回落，工业硅的成本支撑明显减弱，进而带动价格同步下行。"郑 非凡解释称，工业硅对煤炭的依赖，主要体现在碳质还原剂的直接消耗以及火电电价的间接传导。自去 年年底以来，煤炭价格与工业硅价格高度相关，煤价波动会对硅价形成显著影响。 库存方面，当前工业硅库存出现小幅增加态势。根据百川盈孚数据，截至9月26日当周，工业硅现货库 存为44.50万吨，环比增加0.54%。 展望后市，方富强认为，大厂持续增产或带动工业硅供应增长，而多晶硅短期仍有限产预期，或导致工 业硅需求走弱。整体来看，工业硅基本面偏弱，价格或维持偏弱震荡态势。 蔡定洲也认为，尽管当前工业硅行业供需双增，但去库周期基本结束，甚至存在累库迹象，反映出基本 面已转向宽松。考虑两大主产区供应增减不一，同时核心消费终端 ...

Report Summary 1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - During the week from September 1st to 5th, 2025, the price of industrial silicon in the futures market fluctuated upward, while the spot market remained stable. The main contract of industrial silicon futures showed a trend of first falling and then rising, with relatively sharp fluctuations and a significant increase in trading volume, indicating intense competition between long and short positions [2]. 3. Summary by Relevant Catalogs 3.1 Futures Market - **Contract Price**: The price of industrial silicon futures fluctuated during the week, showing a pattern of two down - days and three up - days. By the end of the week, the main contract (si2511) rose 450 points, closing at 8,820 points, with a maximum of 8,920 points and a minimum of 8,270 points. The trading volume was 1,916,401 lots, which was higher than the average level in the past period, in line with the characteristics of an adjustment and correction market [3]. - **Variety Market**: Among the industrial silicon futures contracts, the price of the industrial silicon (si2608) contract was the highest and remained relatively stable, while the price of the industrial silicon (si2509) contract was the lowest [6]. 3.2 Spot Market - **Spot Market Conditions**: The spot price of industrial silicon fluctuated slightly this week. As of September 5th, the price of East China oxygen - containing 553 silicon remained at 11,800 yuan/ton, the price of East China non - oxygen - containing 553 silicon remained at 11,500 yuan/ton, the price of East China 421 silicon remained at 12,200 yuan/ton, the price of East China organic silicon - used 421 silicon remained at 12,800 yuan/ton, the price of 99 silicon (Xinjiang) remained at 10,950 yuan/ton, and the price difference between 421 and 553 was 400 yuan/ton [7]. - **Basis Data**: The spot price in East China remained stable during the week, while the futures price rose slightly. The basis was positive and narrowed, with a basis of 130 yuan/ton during the week [8]. 3.3 Influencing Factors - **Latest News**: On the supply side, the production of industrial silicon is expected to decline in September. Although the current silicon price has fallen below the lowest cost line in the southwestern region during the wet season, some enterprises have locked in the selling price through selling hedging, so there is no obvious production cut for the time being. However, after the delivery of hedging orders, silicon factories will cut production due to the inability to accept long - term low prices. In terms of regions, although there is a resumption of production in Xinjiang, the overall resumption rhythm and capacity release are limited; Yunnan and Sichuan are struggling near the cost line, and production enthusiasm is affected [10]. - **Technical Analysis**: Currently, the cumulative main buying of industrial silicon is greater than the main selling, and the main buying has been strong for two consecutive days, indicating strong buyer sentiment. However, from a longer - term and overall supply - demand perspective, industrial silicon still faces significant upward pressure. Whether this rebound can continue depends on changes in the fundamentals and the subsequent sustainability of funds [11]. 3.4 Market Outlook - Overall, the spot price of industrial silicon remained stable this week without significant fluctuations. However, market feedback shows that the spot trading activity is not high, and traders and downstream enterprises are cautious in purchasing, mainly for rigid demand, with strong market wait - and - see sentiment [13][14].

1. Report Industry Investment Rating - Not mentioned in the provided content 2. Core View of the Report - Industrial silicon spot prices are generally stable, while futures prices continue to oscillate within a range without clear directional guidance, with a balanced drive from both long and short funds. The fundamentals show an increase in both supply and demand, maintaining a loose balance. The anti - involution policy sets a bottom tone, but without actual policy implementation in the industrial silicon industry, the spot prices are only stable and not rising, and the market lacks a major driving force. In the short term, it is expected to operate in a convergent triangular and volume - shrinking oscillation between 8000 - 9000 yuan/ton, and interval operation is recommended [4] 3. Summary by Relevant Catalogs 3.1 Market Performance - Industrial silicon futures prices mainly oscillated. The closing price of Si2511 was 8675 yuan/ton, with a decline of 1.14%.
