细分地区来看，主产区生产积极性高，内蒙古地区最新日均产量为14710吨，较低位累计增加1460吨。 前期检修的工厂复产后负荷不断提升，叠加新增产能投放，预计后续产量在高位继续攀升。同时，近期 宁夏、云南地区产量回升也十分明显，最新产量分别为7060吨/日、2470吨/日，均已创年内新高，且处 于近年来同期高位。其中云南地区产量处于高位主要是因为丰水期电价偏低。目前两地暂无工厂减产计 划，预计产量维持高位。 当前，锰硅需求虽表现尚可，但也存在隐忧，而供应方则维持在高位。 市场情绪迎切换 本轮锰硅价格下行呈现出基差走强的态势。引发期价下行的原因主要有以下两方面： 一方面，市场情绪发生切换，"反内卷"交易逻辑逐渐降温。前期领涨品种开始进行高位调整，乐观情绪 趋于弱化。同时，近期公布的7月国内宏观数据显示，房地产市场延续弱势，而基建投资增速下滑，进 一步加剧了市场情绪的切换。 另一方面，成本端有所松动。前期支撑锰硅价格从低位回升的主要产业逻辑是焦炭价格强势导致成本上 升。然而，自8月中旬以来，焦炭期价出现回落，主力合约价格从高位累计跌幅超过9.7%，进而带动了 锰硅期价的下行。 供应压力偏大 预期交易权重趋弱，锰硅市 ...

The weighted contract positions increased by 1889 lots to 323,092 lots [11][13]. b. Fundamental Analysis - For industrial silicon, the problems of over - capacity, high inventory, and insufficient demand have not changed. The demand in August can provide some support, but it is expected to fluctuate weakly. For polysilicon, the supply - demand situation is weak, and it is expected to fluctuate widely [12][13][14]. Glass and Soda Ash a. Price and Inventory Data - The spot price of glass in Shahe was 1160 yuan, unchanged from the previous day, and that in Central China was 1090 yuan, also unchanged. As of August 14, 2025, the total inventory of national float glass sample enterprises was 63.426 million heavy boxes, up 2.55% month - on - month. The spot price of soda ash was 1230 yuan, down 30 yuan from the previous day. As of August 18, 2025, the total inventory of domestic soda ash manufacturers was 1.8973 million tons, up 0.18% from last Thursday [16][17]. b. Fundamental Analysis - For glass, although the fundamentals are under pressure, the price adjustment space is limited. In the long - term, it follows macro - sentiment. For soda ash, it is expected to fluctuate in the short - term, and the price center may gradually rise in the long - term, but the upward space is limited [16][17].

Report Overview - The report is a black metal R & D report focusing on ferroalloys, including market information, market analysis, and relevant charts, dated August 19, 2025 [2] 1. Market Information Futures - SF main contract closed at 5678, down 202 for the day and 142 for the week, with a trading volume of 372,552 (up 155,765) and an open interest of 214,474 (up 18,596) [4] - SM main contract closed at 5914, down 206 for the day and 196 for the week, with a trading volume of 193,093 (up 80,701) and an open interest of 114,885 (down 27,813) [4] Spot - For ferrosilicon, 72%FeSi in Inner Mongolia, Ningxia, and Qinghai decreased by 50 - 100 yuan/ton, while in Jiangsu and Tianjin it remained stable or increased slightly [4] - For silicomanganese, 6517 silicomanganese in most regions decreased by 20 - 100 yuan/ton [4] Basis/Spread - Ferrosilicon basis in Inner Mongolia, Ningxia, and Qinghai improved, while the SF - SM spread was -236, up 4 for the day and 54 for the week [4] Raw Materials - Manganese ore prices in Tianjin decreased slightly, and the price of semi - coke small materials in some regions increased [4] 2. Market Analysis Trading Strategy - On August 19, ferroalloy futures prices dropped significantly. The SF main contract fell 3.44%, and the SM main contract fell 3.37% [7] - For ferrosilicon, spot prices were weak on the 19th. Supply increased rapidly, while steel output growth was limited. After the sharp drop, the futures price is close to the cost in some regions, and short - selling profit - loss ratio is not high, so short positions can be partially reduced [7] - For silicomanganese, manganese ore and spot prices decreased. Supply also increased rapidly, and there are risks on the demand side. Similar to ferrosilicon, short - selling profit - loss ratio is not high, and short positions can be partially reduced [7] - Unilateral: Short positions can be partially reduced; Arbitrage: Consider cash - and - carry arbitrage when the basis is low; Options: Sell straddle option combinations on rallies [8] Important Information - Starting from August 19, 2025, Shagang reduced the scrap steel price by 30 yuan/ton [9] - On the 19th, the quotes of manganese ore in Tianjin Port were announced [9] 3. Relevant Attachments - The report includes multiple charts showing ferroalloy main contract trends, spreads, basis, spot prices, electricity prices, production costs, and production profits [11][15][19][24]
