Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core View The report suggests a wait - and - see approach for both manganese - silicon and silicon - iron due to factors such as supply - demand balance and coal price trends. For manganese - silicon, with overall loose supply - demand but low inventory and stable thermal coal prices, significant price trends are unlikely. For silicon - iron, its price movement depends on energy prices, and the supply - demand contradiction is limited [43]. 3.

In August 2025, China's excavator output was 27,590, a year - on - year increase of 13.2%. From January to August 2025, China's excavator output was 245,556, a year - on - year increase of 17.6% [5]. - **Manganese - Silicon Futures and Spot Prices**: The report shows the price changes of manganese - silicon futures and spot in different regions, including the basis, year - on - year changes, 30 - day price changes, and weekly price changes. For example, in Inner Mongolia, the basis was 110, with a year - on - year increase of 0.53%, a 30 - day decrease of 0.35%, and a weekly increase of 0.88%, and the price was 5730 [9]. - **Silicon - Iron Futures and Spot Prices**: Although not detailed in the given text, the report also mentions the silicon - iron futures trend and basis situation [13][16]. - **Power Price Changes**: The report presents the power price changes of ferroalloy in different regions such as Ningxia, Qinghai, Yunnan, and Inner Mongolia from June 20, 2023, to August 20, 2025 [19]. Part 2: Manganese - Silicon Industry Chain Overview The report shows the price, import volume, inventory, profit estimation, output, and demand (related to steel output) of manganese ore in the manganese - silicon industry chain from 2019 to 2025 through charts, but no specific numerical data is given in the text [21][24][26][27][30][31]. Part 3: Silicon - Iron Industry Chain Overview The report shows the profit estimation, output, and demand (related to steel output) of silicon - iron in the silicon - iron industry chain from 2019 to 2025 through charts, but no specific numerical data is given in the text [34][38][40]. Part 4: Outlook - **Manganese - Silicon**: Last week, manganese - silicon futures rose, and the spot price increased slightly with a slight decline in the basis. The September bid price of the iconic steel mill was 6000 yuan/ton, slightly higher than expected, but the long - term indecision of downstream bids indicated general demand. The output of manganese - silicon decreased month - on - month, and steel production also decreased. With overall loose supply - demand but low inventory and stable thermal coal spot prices, significant price trends are unlikely, and a wait - and - see approach is recommended [43]. - **Silicon - Iron**: Last week, silicon - iron futures rose, the spot price reached a high and then slightly declined, and the basis changed little. The stable thermal coal spot price and high market expectations for the recovery of thermal coal prices drove the rebound of silicon - iron. In terms of supply - demand, the output last week remained flat, but steel production decreased month - on - month, and the supply - demand contradiction was limited. According to Mysteel statistics, the national capacity utilization rate of 136 independent silicon - iron enterprises was 34.84%, unchanged from last week, and the daily average output was 16,150 tons, unchanged from last week. The trend of silicon - iron depends on energy price changes, and a wait - and - see approach is recommended [43].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints - Expectations are driving the black sector to perform stronger, and ferroalloys will continue to follow the fluctuations of the black sector [1][77][93] - In the short - term, affected by real - demand factors, the black sector may face a downward correction risk after the National Day holiday.

Report Industry Investment Rating No relevant content provided. Core Viewpoints - The steel market was previously driven by macro factors, but currently, the macro - driving force has weakened in the short term, and the fundamentals have not formed an upward drive. After digesting the short - term impact of the Fed's less - than - expected interest rate cut, the steel futures market may turn to a volatile consolidation. The iron ore market has limited price fluctuations, and the price is expected to move in a range. The coal - coke market may see an improvement in the supply - demand structure before the National Day, but the high supply of steel will suppress the rebound height of coal - coke prices. The ferroalloy market is in a game between strong expectations and weak reality, and the supply - demand pressure may weaken. The soda ash market has a pattern of strong supply and weak demand, and the high inventory of the upper - middle reaches restricts the price. The glass market lacks a clear trend and trading logic due to high inventory and weak demand, and the supply - demand pattern of near - term supply exceeding demand remains unchanged [3][20][33][51][62][88]. Summary by Directory Steel - **Macro and Fundamental Analysis**: The Fed's interest rate cut was less than expected, and the market risk preference may be adjusted in the short term. Among the five major steel products, only rebar showed a situation of reduced supply, increased demand, and inventory turning from increase to decrease. The overall steel market is still in the inventory accumulation channel, but the inventory accumulation rate has slowed down, and there is a replenishment expectation before the National Day [3]. - **Price and Spread Data**: Provided the closing prices of rebar and hot - rolled coil futures contracts on September 19 and 18, 2025, as well as the corresponding month - spreads, basis, and spot prices [4][7][10]. Iron Ore - **Market Situation**: The contradiction in the iron ore market is not significant, and the price fluctuation has narrowed. The supply has recovered to a medium - high level, and the overall demand is in a tight balance due to pre - holiday replenishment by steel mills. The profit of steel mills has declined marginally, and the downstream steel demand is average, with inventory accumulation but a slowdown in the inventory accumulation slope [20]. - **Price and Fundamental Data**: Presented the price data of iron ore futures contracts, basis, and spot prices, as well as fundamental data such as daily average hot - metal output, port desilting volume, and global shipping volume [21][27]. Coal - Coke - **Market Outlook**: "Anti - involution" remains the focus of the market in the second half of the year. The market participants' expectations for the future are gradually improving, and there is a possibility of inventory transfer before the National Day to improve the supply - demand structure. However, the high supply of steel will suppress the rebound height of coal - coke prices [33]. - **Price and Spread Data**: Included the cost of coal - coke warehouse receipts, basis, month - spreads, and various profit ratios [38]. - **Spot Price Data**: Provided the spot prices of coking coal and coke, as well as import and export profits [39]. Ferroalloy - **Market Logic**: The trading logic of ferroalloys lies in the expectation of supply - side contraction. The production profit of ferroalloys is declining, and the supply - demand pressure may weaken [51]. - **Data**: Presented the daily data of ferrosilicon and silicomanganese, including basis, month - spreads, and spot prices [52][54]. Soda Ash - **Market Situation**: The market sentiment and focus are volatile. The supply of soda ash is expected to remain high in the long - term, and the demand is stable. The inventory of the upper - middle reaches is high, and the supply - demand pattern of strong supply and weak demand remains unchanged [62]. - **Price and Spread Data**: Provided the closing prices of soda ash futures contracts, month - spreads, and basis [63]. - **Spot Price Data**: Showed the spot prices of heavy and light soda ash in different regions and their spreads [67]. Glass - **Market Analysis**: The high inventory of the upper - middle reaches and weak demand limit the price of glass. The supply - demand pattern of near - term supply exceeding demand remains unchanged, and the price lacks a clear trend and trading logic [88]. - **Price and Spread Data**: Presented the closing prices of glass futures contracts, month - spreads, and basis [89]. - **Sales Data**: Provided the daily sales data of glass in different regions [90].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - For ferrosilicon, supply is relatively stable, demand is limited by slow steel inventory reduction, and the cost side provides support. The slow progress of steel inventory reduction is the biggest risk point [5]. - For silicomanganese, both supply and demand decline slightly, and the cost side has strong support. It is expected to fluctuate at the bottom this week [5]. - The trading strategies include a bottom - oscillating trend for single - side trading, waiting and seeing for arbitrage, and selling straddle combinations on rallies for options [5]. Summary by Directory Chapter 1: Comprehensive Analysis and Trading Strategies Comprehensive Analysis - **Ferrosilicon**: Supply is stable with a slight increase in production. The rumor of supply contraction was refuted. Demand is affected by poor steel inventory reduction and low profits, and there is limited room for further growth in hot metal production. The cost side is supported by strong thermal coal prices and stable - to - strong electricity prices in ferroalloy production areas [5]. - **Silicomanganese**: Supply decreases slightly, but the absolute production volume is still high compared to the same period in previous years. Demand is dragged down by the continuous compression of steel profits and the decline in steel production. The cost side is supported by the relatively low manganese ore port inventory compared to last year and stable overseas mine quotes [5]. Strategies - **Single - side**: Bottom - oscillating [5]. - **Arbitrage**: Wait and see [5]. - **Options**: Sell straddle combinations on rallies [5]. Chapter 2: Core Logic Analysis No relevant content provided.

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The overall atmosphere in the commodity market is weak, and the prices of finished steel products continue to fluctuate weakly. Although the global liquidity easing is expected to drive the recovery of the manufacturing industry and indirectly boost steel demand in the long - term, currently, the demand for both rebar and hot - rolled coils is weak, and steel prices may still decline if demand cannot be effectively restored [2]. - The supply of iron ore has increased, with overseas shipments reaching a high level in the same period. Although the demand for iron ore remains strong in the short - term, the price is expected to fluctuate as the profitability of steel mills has been decreasing [5]. - The prices of ferrosilicon and silicomanganese are in a range - bound pattern, and the operation difficulty is high. From a fundamental perspective, they are likely to follow the trend of the black sector, and the operation cost - effectiveness is relatively low [9][11]. - The price of industrial silicon is expected to fluctuate. Although there is some support from the demand side, the problems of over - capacity, high inventory, and insufficient demand still exist. The price of polysilicon is more influenced by policies, and the inventory reduction space of the whole industry is limited [14][17]. - The glass market shows a differentiated trend, with supply slightly increasing and inventory decreasing marginally. However, terminal demand is weak, and it is expected to maintain a volatile trend. The demand for soda ash is average, and it is expected to fluctuate narrowly [20][22]. Summary by Related Catalogs Steel Products Rebar - **Market Quotes**: The closing price of the rebar main contract was 3147 yuan/ton, down 21 yuan/ton (- 0.66%) from the previous trading day. The registered warehouse receipts decreased by 14137 tons, and the position increased by 36313 lots. In the spot market, the prices in Tianjin and Shanghai decreased [1]. - **Strategy Viewpoints**: The demand for rebar is weak even in the traditional peak season. If demand cannot be effectively restored, steel prices may decline. Attention should be paid to the policy trends of the Fourth Plenary Session [2]. Hot - Rolled Coils - **Market Quotes**: The closing price of the hot - rolled coil main contract was 3354 yuan/ton, down 36 yuan/ton (- 1.06%) from the previous trading day. The registered warehouse receipts decreased by 13892 tons, and the position increased by 20862 lots. The spot prices in Lecong and Shanghai remained unchanged [1]. - **Strategy Viewpoints**: Although hot - rolled coils have some resilience, the overall demand is still weak. The inventory has slightly increased, and steel prices may decline if demand cannot be effectively restored [2]. Iron Ore - **Market Quotes**: The main contract (I2601) of iron ore closed at 800.00 yuan/ton, with a change of - 0.56% (- 4.50), and the position decreased by 936 lots to 53.35 million lots. The weighted position was 84.20 million lots. The spot price of PB powder at Qingdao Port was 792 yuan/wet ton, with a basis of 42.25 yuan/ton and a basis rate of 5.02% [4]. - **Strategy Viewpoints**: The supply of iron ore has increased, with the shipments from Australia, Brazil, and non - mainstream countries all rising. The demand is strong in the short - term, but the profitability of steel mills has been decreasing. The port inventory has slightly decreased, and the price is expected to fluctuate [5]. Ferrosilicon and Silicomanganese Silicomanganese - **Market Quotes**: The main contract (SM601) of silicomanganese closed down 0.33% at 5970 yuan/ton. The spot price in Tianjin was 5820 yuan/ton, unchanged from the previous day, with a premium of 40 yuan/ton to the futures price [8]. - **Strategy Viewpoints**: The price of silicomanganese is in a range - bound pattern. It is recommended to wait and see, focusing on the resistance near 6000 yuan/ton and the support between 5600 - 5650 yuan/ton [9]. Ferrosilicon - **Market Quotes**: The main contract (SF511) of ferrosilicon closed down 0.17% at 5756 yuan/ton. The spot price in Tianjin was 5750 yuan/ton, unchanged from the previous day, with a discount of 6 yuan/ton to the futures price [8]. - **Strategy Viewpoints**: The price of ferrosilicon is also in a range - bound pattern. It is recommended to wait and see, focusing on the resistance near 5800 yuan/ton and the support between 5400 - 5450 yuan/ton [9]. Industrial Silicon and Polysilicon Industrial Silicon - **Market Quotes**: The main contract (SI2511) of industrial silicon closed at 8905 yuan/ton, down 0.67% (- 60).

The spot prices of 553 and 421 in East China remained unchanged, with a basis of 195 yuan/ton and - 105 yuan/ton respectively [13]. - **Strategy Viewpoints**: The price of industrial silicon is expected to fluctuate. Although the demand from downstream polysilicon and silicone DMC has increased, the problems of over - capacity, high inventory, and insufficient demand still exist. Attention should be paid to the progress of capacity reduction and the resumption of production on the supply side [14][15]. Polysilicon - **Market Quotes**: The main contract (PS2511) of polysilicon closed at 53205 yuan/ton, down 0.53% (- 285). The weighted position decreased by 5951 lots to 283593 lots.

The supply is close to the high level in the same period, and the inventory reduction space of the whole industry is limited. Attention should be paid to the progress of capacity integration and downstream price transfer [17]. Glass and Soda Ash Glass - **Market Quotes**: The main contract of glass closed at 1208 yuan/ton on Thursday afternoon, down 2.11% (- 26). The prices in North China and Central China were 1150 yuan and 1140 yuan respectively, with the former remaining unchanged and the latter increasing by 10 yuan. The weekly inventory of float glass sample enterprises decreased by 67.5 million cases (- 1.10%). The atmosphere in the market was bearish [19]. - **Strategy Viewpoints**: The spot market shows a differentiated trend. The supply has slightly increased, and the inventory has decreased marginally due to pre - holiday stocking. However, terminal demand is weak, and it is expected to maintain a volatile trend [20]. Soda Ash - **Market Quotes**: The main contract of soda ash closed at 1306 yuan/ton on Thursday afternoon, down 2.10% (- 28). The price in Shahe decreased by 23 yuan to 1216 yuan.

Report Industry Investment Rating No information provided in the given content. Core Viewpoints - The overall atmosphere in the commodity market has warmed up, but the prices of finished products are showing a volatile and slightly stronger trend. The economic data in August slowed down and were lower than expected, increasing the possibility of more stimulus policies. The real - estate sales are still weak, and it will take time for the real - estate market to stabilize. The export volume decreased slightly last week and remains in a weak and volatile pattern. The demand for rebar is weak, while the demand for hot - rolled coils is relatively firm, and the trends of rebar and hot - rolled coils have diverged. Steel mills' profits are gradually narrowing, and the weak characteristics of the market are becoming more prominent. If the subsequent demand cannot be effectively repaired, steel prices still have the risk of decline. The raw material prices are relatively firm, and continuous attention should be paid to the possible disturbances caused by domestic and overseas macro - policies [3]. - The short - term iron ore price is expected to fluctuate. The overseas iron ore shipments have rebounded to the same - period high, the proximal arrival volume has decreased slightly, and the short - term demand support still exists. The steel mill profitability rate continues to decline, and the port and steel mill inventories have both increased slightly. The terminal data shows that the apparent demand for the five major steel products has increased to some extent, and the inventory accumulation speed has slowed down. The rebar data is weak, and the difference between hot - rolled coils and rebar has been strong recently. Attention should be paid to whether the internal contradictions of finished products will be transmitted to the raw material end [6]. - For manganese silicon and ferrosilicon, the prices of their main contracts fluctuated higher on September 17. From a disk perspective, they are in a range - bound pattern. The fundamentals of manganese silicon are not ideal, mainly due to high - level supply and weak demand in the building materials sector. Ferrosilicon has no obvious contradictions and drivers in its supply - demand fundamentals. Both are likely to follow the trend of the black - sector market, and their operational cost - effectiveness is relatively low [8][9][11]. - The price of industrial silicon fluctuated and strengthened. The fundamentals of over - capacity, high inventory, and insufficient effective demand have not changed fundamentally. The short - term valuation is neutral. If the market continues to discuss topics such as "anti - involution", the price may rise further under the expected drive; otherwise, the weak fundamentals will limit the price increase. The price of polysilicon is more influenced by policy narratives. Before the actual progress of capacity integration, the disk price is prone to fluctuate with the ebb and flow of sentiment [13][14][16]. - For glass, the industry supply has increased slightly, and the enterprise inventory has decreased. The pre - holiday stocking has promoted inventory reduction, but the market supply is still abundant, and the terminal demand is weak. It is recommended to be cautiously bullish. For soda ash, the industry supply has contracted slightly, mainly due to the maintenance of production lines. Some downstream enterprises have pre - holiday stocking needs, but most are still purchasing based on rigid demand. The market trading atmosphere is tepid, and it is expected to fluctuate within a narrow range [18][19]. - Although the black - sector prices still have the risk of short - term phased decline under the influence of real - demand, in the face of the subsequent certainty of overseas fiscal and monetary easing, and the opening of China's policy space after the US enters the interest - rate cut cycle, the black - sector may gradually have the cost - effectiveness of long - allocation in the future, and the key node may focus on the "Fourth Plenary Session" around mid - October [10].
