Report Industry Investment Rating No relevant content provided. Core Viewpoints - The steel price continues to fluctuate after the macro - sentiment fades, and the glass and soda ash markets fluctuate due to repeated market sentiment. The double - silicon market sentiment cools down, and ferroalloy futures decline slightly [1][3] - For glass, the supply - demand contradiction is large, and it needs low prices and low profits to reduce supply. For soda ash, the supply - demand imbalance will intensify, and it needs to limit capacity release through losses [1] - Both the silicon manganese and silicon iron industries have obvious over - supply, and need to limit production through losses. Their prices are expected to fluctuate with the sector [3] Market Analysis Glass and Soda Ash - **Glass**: The glass futures oscillated weakly yesterday, with the main 2601 contract down 1.76%. Spot trading sentiment is average. Supply is stable in production and sales, but factory inventories are growing. The supply - demand contradiction is large, and short - term premium suppresses prices. Later, attention should be paid to the performance of peak - season demand [1] - **Soda Ash**: The soda ash futures declined yesterday, with the main 2601 contract down 1.8%. Spot prices were adjusted downwards, and downstream buyers purchase at low prices. Supply is increasing as summer maintenance nears the end. Consumption is currently stable but is expected to weaken with new capacity coming online. The supply - demand imbalance will intensify, and losses are needed to limit capacity release. Attention should be paid to the impact of "anti - involution" policies on the photovoltaic sector [1] Double - Silicon - **Silicon Manganese**: The silicon manganese futures declined yesterday. The main contract closed at 5862 yuan/ton, down 36 yuan/ton from the previous day. The spot market oscillated. Production and sales increased month - on - month, and inventories decreased. The cost increased slightly due to a small increase in manganese ore prices. The industry has obvious over - supply, and losses are needed to limit production. Prices are expected to follow the sector, and attention should be paid to manganese ore cost support, inventory, and ore shipments [3] - **Silicon Iron**: The silicon iron futures declined slightly yesterday. The main contract closed at 5656 yuan/ton, down 24 yuan/ton from the previous day. The spot market sentiment was average, and prices were slightly adjusted. Production and sales increased, and factory inventories decreased, but absolute inventories are still high, suppressing prices. The industry has obvious over - supply, and losses are needed to limit production. Prices are expected to follow the sector, and attention should be paid to steel mill production restrictions, cost support, and industrial policies [3] Strategies - **Glass**: Oscillate weakly [2] - **Soda Ash**: Oscillate weakly [2] - **Silicon Manganese**: Oscillate [4] - **Silicon Iron**: Oscillate [4]

Report Industry Investment Rating - The mid - term outlook for the black building materials industry is "oscillation" [5]. - The mid - term outlooks for individual varieties such as iron ore, coke, etc. are also "oscillation" [7][8][10][11] Core Viewpoints - The black market has limited upside potential due to weak terminal demand expectations, but there is support from supply disruptions and downstream restocking needs. The market will mainly oscillate, and attention should be paid to policy implementation and terminal demand performance [5]. Summary by Related Catalogs Overall Market Analysis - The black market's upward movement lacks drive, with the previous day's gains mostly erased and coking coal leading the decline. Supply constraints for furnace materials remain, and the downside space for prices is limited. Steel apparent demand is weak, and it is in the restocking window before the peak season. If there is topic - driven news, there is a small rebound space; otherwise, it will oscillate. Attention should be paid to future demand and furnace material supply recovery [1]. By Variety Iron Ore - Overseas mine shipments decreased, 45 - port arrivals slightly declined, and total supply is relatively stable. Iron ore demand is expected to remain high as iron - making water production increases slightly. Port inventories decreased slightly. With limited negative driving factors in the fundamentals, prices are expected to oscillate [2][7][8]. Coking Coal - Some coal mines have resumed production, but some are still restricted by accidents and safety inspections. Import volumes are high but have recently declined briefly. Coking coal's short - term rigid demand has slightly decreased, and some mines have inventory accumulation, but overall inventory pressure is not significant. The short - term futures market still has support [2][12]. Coke - The eighth round of price increases has started, with regional differentiation. Some areas' coking production is restricted. Upstream coking enterprises' inventories are still low, and short - term supply and demand remain tight under simultaneous coking and steel production restrictions. Before the parade, the futures market still has support [11]. Alloys - **Manganese Silicon**: Before the parade, manufacturers' raw material restocking is nearly finished, port prices are loosening, and supply pressure is increasing. In the long - term, the supply - demand relationship may become looser, and prices may face downward pressure [2]. - **Silicon Iron**: The current market inventory pressure is not large, and short - term prices are expected to oscillate. However, in the long - term, the supply - demand gap is expected to be filled, and there are concerns in the fundamentals [2]. Glass - After the futures price decline, the spot market sentiment has cooled. Supply is expected to remain stable, and there is some inventory accumulation upstream. Cost support has strengthened due to rising coal prices, but the fundamentals are still weak, and short - term futures and spot prices are expected to oscillate widely [2][13]. Soda Ash - The supply surplus pattern remains unchanged. After the futures price decline, spot trading volume has increased slightly. In the long - term, the price center will decline to promote capacity reduction [2][5][15]. Scrap Steel - The arrival volume at steel mills has decreased, and the fundamentals' contradictions are not prominent. Due to the pressure on finished product prices, electric furnace profits are low, but resources are still tight, and short - term prices are expected to oscillate [9].

Core Viewpoint - The domestic soda ash market is experiencing a stable yet weak trend, with prices showing little fluctuation across various regions [2][3]. Price Summary - Light soda ash prices in North China range from 1220 to 1320 CNY/ton, while heavy soda ash prices are between 1240 and 1350 CNY/ton [2]. - Northeast region prices for light soda ash are between 1330 and 1410 CNY/ton, and for heavy soda ash, they range from 1340 to 1500 CNY/ton [2]. - The soda ash price index for light soda ash is 1210, remaining unchanged, while the heavy soda ash index is 1254.29, reflecting a decrease of 1.43, or -0.11% [3]. Supply and Demand Analysis - Supply is tightening as companies like Wucai Soda Industry are undergoing maintenance, and Shaanxi Xinghua has plans for repairs, leading to an overall contraction in supply [2]. - Downstream demand remains limited, with companies primarily maintaining just-in-time inventory, which does not provide substantial support to the market [2]. Futures Market Dynamics - On August 26, the main contract for soda ash (SA2601) opened at 1336 CNY/ton and closed at 1311 CNY/ton, showing a daily decline of 1.80% [5]. - The market sentiment is affected by a general decline in the chemical sector, with high inventory levels persisting despite supply-side maintenance [5]. Future Market Predictions - There are upcoming maintenance plans from some companies, which may cause slight fluctuations in supply [6]. - Demand is expected to remain cautious, with limited order releases, and the overall inventory in the industry is still high [6].
