1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The overall atmosphere in the commodity market cooled yesterday, and the prices of finished steel products declined slightly. The demand for finished steel products is clearly weak, the profits of steel mills are gradually shrinking, and the weak characteristics of the market are becoming more prominent. If the subsequent demand cannot be effectively improved, the prices may continue to decline. [3] - The supply and demand contradictions of iron ore are not prominent for the moment, and its price is expected to fluctuate in the short - term. Attention should be paid to the subsequent shipping progress and the impact of safety inspections and environmental protection restrictions. [6] - The prices of ferrous alloys have dropped rapidly. In the short - term, it is not recommended for speculative funds to participate excessively, while hedging funds can seize hedging opportunities. The fundamental problems of over - supply in the manganese - silicon and silicon - iron industries remain. [7][8][9] - Industrial silicon is expected to fluctuate between 8300 - 9300 yuan/ton. Polysilicon continues the pattern of "weak reality, strong expectation" and is expected to have high - volatility. [12][13][14] - The price of glass is expected to fluctuate weakly in the short - term, and the price of soda ash is expected to fluctuate. In the long - term, the price of soda ash may gradually rise, but the increase is limited. [16][17] 3. Summary by Related Catalogs Steel - Price and Position Data: The closing price of the rebar main contract was 3113 yuan/ton, down 25 yuan/ton (-0.79%) from the previous trading day. The closing price of the hot - rolled coil main contract was 3367 yuan/ton, down 22 yuan/ton (-0.64%) from the previous trading day. [2] - Market Analysis: The export volume of steel increased slightly this week but remained in a weak and volatile pattern. The output of rebar decreased significantly this week, demand improved slightly but remained weak, and inventory continued to accumulate. The demand for hot - rolled coils continued to rise, production increased rapidly, and inventory increased for six consecutive weeks. [3] Iron Ore - Price and Position Data: The main contract of iron ore (I2601) closed at 776.50 yuan/ton, with a change of -1.33% (-10.50), and the position changed to 45.29 million hands. The weighted position was 80.85 million hands. The spot price of PB fines at Qingdao Port was 770 yuan/wet ton, with a basis of 41.52 yuan/ton and a basis rate of 5.08%. [5] - Market Analysis: Overseas iron ore shipping was stable. Australian shipping increased, Brazilian shipping decreased, and non - mainstream shipping decreased slightly. The recent arrival volume decreased. The daily average pig iron output was basically flat, the steel mill profitability rate continued to decline, port inventory increased slightly, and steel mill imported ore inventory decreased slightly. [6] Manganese Silicon and Silicon Iron - Price and Position Data: On August 26, the main contract of manganese silicon (SM601) closed down 0.61% at 5862 yuan/ton, and the main contract of silicon iron (SF511) closed down 0.42% at 5656 yuan/ton. [7] - Market Analysis: The prices of ferrous alloys dropped rapidly due to the weakening of the "anti - involution" sentiment. The over - supply situation of manganese silicon remained unchanged, and production continued to rise. There were no obvious fundamental contradictions in silicon iron, and supply also continued to increase. [8][9] Industrial Silicon and Polysilicon - Industrial Silicon - Price and Position Data: The closing price of the main contract of industrial silicon (SI2511) was 8515 yuan/ton, with a change of -1.84% (-160). The weighted contract position changed to 526046 hands. [11] - Market Analysis: The problems of over - capacity, high inventory, and insufficient demand of industrial silicon remained. Production continued to rise, and the support from the demand side was limited. It was expected to fluctuate between 8300 - 9300 yuan/ton. [12] - Polysilicon - Price and Position Data: The closing price of the main contract of polysilicon (PS2511) was 50985 yuan/ton, with a change of -1.15% (-595). The weighted contract position changed to 320439 hands. [13] - Market Analysis: Polysilicon continued the "weak reality, strong expectation" pattern. Production continued to increase, and the number of warehouse receipts increased rapidly. It was expected to have high - volatility. [14] Glass and Soda Ash - Glass - Price and Inventory Data: The spot price in Shahe was 1138 yuan, unchanged from the previous day, and the spot price in Central China was 1070 yuan, up 10 yuan from the previous day. As of August 21, 2025, the total inventory of national float glass sample enterprises was 63.606 million heavy boxes, up 180,000 heavy boxes (0.28%) from the previous period. [16] - Market Analysis: The production of glass remained high, inventory pressure increased slightly, and downstream real - estate demand did not improve significantly. The price adjustment space was limited, and the market expected policy support. It was expected to fluctuate weakly in the short - term. [16] - Soda Ash - Price and Inventory Data: The spot price of soda ash was 1200 yuan, down 20 yuan from the previous day. As of August 25, 2025, the total inventory of domestic soda ash manufacturers was 1.8881 million tons, down 22,700 tons (1.19%) from last Thursday. [17] - Market Analysis: The price of soda ash fluctuated with the coal - chemical sector. The downstream demand was difficult to improve quickly, and the price was expected to fluctuate in the short - term and gradually rise in the long - term, but the increase was limited. [17]
