1. Report Industry Investment Rating - The medium - term outlook for the industry is "Oscillation" [6] 2. Core View of the Report - Macro - disturbances have temporarily ended, and the off - season fundamentals are poor. Prices still face downward adjustment pressure, and attention should be paid to the disturbance of winter storage and replenishment expectations [6] 3. Summary by Relevant Catalogs 3.1 Iron Element - **Iron Ore**: Overseas mine shipments increased slightly month - on - month, arrivals decreased significantly, port inventories continued to accumulate, and steel mill inventories decreased. Iron water production continued to decline sharply, steel mill profitability weakened, and replenishment demand was released slowly. Short - term ore prices are expected to oscillate [1][8][9]. - **Scrap Steel**: Supply increased, demand was stable, and inventories accumulated. However, electric furnace profits were acceptable, and the demand from long - and short - process steel enterprises for scrap steel still had support. It is expected that the spot price will follow the decline [10]. 3.2 Carbon Element - **Coke**: The cost support has weakened, and the expectation of the second - round price cut is strong. But the coking and steel enterprises have gradually started winter storage and replenishment, so the fundamentals still provide support. The current disk valuation is too low, and there is insufficient drive for a significant downward movement. It is expected to oscillate following coking coal [2][14]. - **Coking Coal**: The fundamentals have marginally improved, but the market remains pessimistic in the short term due to bearish funds. After the delivery is settled and the mid - and downstream winter storage and replenishment are gradually launched, the fundamentals and market sentiment will gradually recover, and the disk valuation is expected to repair upward [2][15]. 3.3 Alloys - **Manganese Silicon**: High costs support prices, but the market supply - demand is loose, cost transmission is difficult, and there is insufficient drive for the disk to rise. It is expected that the manganese silicon futures price will oscillate at a low level following the sector [2][18][19]. - **Silicon Ferrosilicon**: High costs support the price bottom, but the market has weak supply and demand, and there are difficulties in destocking. Caution should be exercised regarding the upward space of the disk. It is expected that the silicon ferrosilicon futures price will oscillate at a low level following the sector [2][20]. 3.4 Glass and Soda Ash - **Glass**: There is still an expectation of supply disturbances, but the mid - and downstream inventories are moderately high. The current supply - demand is still in surplus. If there is no more cold repair by the end of the year, high inventories will always suppress prices, and it is expected to oscillate weakly; otherwise, prices will rise [2][16]. - **Soda Ash**: The overall supply - demand is still in surplus. In the short term, it is expected to oscillate. In the long run, the supply surplus pattern will further intensify, and the price center will continue to decline to promote capacity reduction [2][6][18]. 3.5 Steel - Spot market transactions were weak, steel production decreased, and demand was weakening. The inventory of steel continued to decline, but the inventory level was still higher than the same period last year, and there were signs of inventory accumulation in steel mills. The steel disk is expected to continue its weak adjustment [8]. 3.6 Commodity Index - On December 11, 2025, the comprehensive index of CITICS Futures commodities, the specialty index (Commodity 20 Index, Industrial Products Index) all declined, and the steel industry chain index also showed a downward trend in different time - periods [102][104]

Report Industry Investment Ratings - Urea: なな女 - Methanol: ☆☆☆ - Styrene: ★☆☆ - Polypropylene: ★☆☆ - Plastic: ★☆☆ - PVC: ☆☆☆ - Caustic Soda: ☆☆☆ - PX: ☆☆☆ - PTA: ☆☆☆ - Ethylene Glycol: なな女 - Short Fiber: ☆☆☆ - Glass: ななな - Soda Ash: ☆☆☆ - Bottle Chip: ☆☆☆ - Propylene: ☆☆☆ [1] Core Views - The overall chemical market shows a complex situation with different trends in various products. Some products are under downward pressure, while some have certain support factors. The market is affected by supply, demand, inventory, and raw material price fluctuations. [2][3][5] Summary by Relevant Catalogs Olefins - Polyolefins - Propylene futures declined due to increased supply and weakened downstream buying sentiment, but inventory control provided some support [2]. - Plastic and polypropylene futures fell. Polyethylene had weak spot prices due to sufficient supply and low downstream demand. Polypropylene faced increased production and limited demand, resulting in an imbalanced supply - demand situation [2]. Pure Benzene - Styrene - Pure benzene futures had low - level fluctuations, with falling spot prices and high port inventory, but future supply - demand pressure may ease. Consider long - short spreads on dips in the medium term [3]. - Styrene futures declined due to falling crude oil prices, weak pure benzene fundamentals, and expected increased supply [3]. Polyester - PX and PTA continued to fall due to lower oil prices. PX is expected to be strong in the medium term, and PTA's processing margin is expected to recover [5]. - Ethylene glycol had a slight rebound but still faced supply pressure, with long - term pressure from planned new production [5]. - Short fiber's load was high, with a slight inventory increase. Its long - term supply - demand pattern is good. Bottle chip demand weakened, with a weak processing margin and over - capacity pressure [5]. Coal Chemical Industry - Methanol futures prices fell, while the spot market was relatively stable. The market is expected to fluctuate weakly in the short term due to supply - demand factors [6]. - Urea futures were firm in a range. Although there was inventory reduction, high production and weakening market sentiment may lead to continued range - bound trading [6]. Chlor - Alkali Industry - PVC continued to decline due to weak demand and high inventory. It is expected to operate in a low - level range [7]. - Caustic soda was at a low level, with high inventory, increased production, and weak demand, leading to profit compression [7]. Soda Ash - Glass - Soda ash fell below 1100 yuan due to cost and supply pressure, with a high - inventory situation. It is in a long - term supply - surplus pattern [8]. - Glass continued to decline. Although there was inventory reduction, recent sales weakened, and long - term cold - repair may be forced by low profits [8].

1. Report Industry Investment Rating - No relevant information provided 2. Core View of the Report - In the short - term, the decline of glass prices is expected to slow down, and attention should be paid to the upper resistance level of 1030 yuan/ton. The price of soda ash continues to decline, breaking through the previous low - level support, and subsequent attention should be paid to the integer support level of 1000 yuan/ton. In the long - term, the forward policy expectations have positive signals, and the "Three Major Projects" fund allocation is accelerating, which is expected to support the demand for infrastructure glass in Q1 2026 [2] 3. Summary by Relevant Catalog 3.1 Futures Market - The closing price of the soda ash main contract is 1094 yuan/ton, down 31 yuan; the closing price of the glass main contract is 964 yuan/ton, down 20 yuan. The soda ash - glass price difference is 130 yuan/ton, down 11 yuan. The positions of the soda ash and glass main contracts decreased by 79,430 hands and 54,739 hands respectively. The net positions of the top 20 soda ash decreased by 3,031, while that of glass increased by 5,254. The exchange warehouse receipts of soda ash decreased by 724 tons, and those of glass increased by 303 tons. The basis of soda ash increased by 31 yuan/ton, and that of glass increased by 16 yuan/ton. The spread between the January and May glass contracts decreased by 6, and that of soda ash decreased by 3 [2] 3.2 Spot Market - The prices of North China heavy - soda ash and Central China heavy - soda ash remained unchanged at 1120 yuan/ton and 1300 yuan/ton respectively. The prices of East China light - soda ash and Central China light - soda ash were stable at 1400 yuan/ton and 1165 yuan/ton respectively. The price of Shahe glass sheets decreased by 4 yuan/ton to 968 yuan/ton, and the price of Central China glass sheets remained at 1110 yuan/ton [2] 3.3 Industry Situation - The weekly operating rate of soda ash plants increased by 0.66 percentage points to 80.74%, and the weekly operating rate of float glass enterprises decreased by 0.89 percentage points to 73.63%. The weekly in - production capacity of glass decreased by 0.28 million tons/year to 15.44 million tons/year, and the number of in - production glass production lines decreased by 2 to 218. The weekly inventory of soda ash enterprises decreased by 3.61 million tons to 150.25 million tons, and the weekly inventory of glass enterprises decreased by 2.92 million heavy boxes to 59.442 million heavy boxes [2] 3.4 Downstream Situation - The cumulative value of newly - started real estate area was 49,061.39 million square meters, an increase of 3,662.39 million square meters, and the cumulative value of real - estate completion area was 34,861 million square meters, an increase of 3,732 million square meters [2] 3.5 Industry News - Some soda ash plants had production adjustments, such as Jiangsu Jingshen Chemical reducing production, Henan Zhongyuan Chemical maintaining stable production, Hubei Shuanghuan keeping stable output, Henan Haohua Junhua starting operation, Tangshan Sanyou reducing production to 70% load, Shandong Haitian Biological Chemical resuming production, Shandong Haihua reducing load, Zhongyan Anhui Hongsifang resuming load, Henan Jinshan reducing production for maintenance, and Chongqing Xiangyu Yanhua resuming production. For glass, the supply contraction trend will be more obvious next week, and the average daily melting volume in Q1 2026 is expected to drop to around 155,000 tons. The regional supply shows a pattern of "local contraction, overall looseness" [2] 3.6 View Summary - The demand side is the core factor suppressing the current market. In the short - term, the decline in construction site start - up rates in the north, limited demand pull from the automotive industry and the export market, and weak terminal receiving willingness have a negative impact on the market. However, forward policy expectations are positive, and the "Three Major Projects" are expected to support infrastructure glass demand in Q1 2026 [2] 3.7 Prompt Attention - This week, the operating rate of soda ash plants declined. Although some plants such as Zhongyan Kunshan increased production and some completed maintenance, many other plants continued maintenance or reduced load. There is no large - scale maintenance plan for subsequent soda ash plants for now, and the supply is expected to increase next week. The demand from the glass industry, the largest downstream of soda ash, has decreased. If the cold - repair of glass production lines is implemented, the demand for heavy - soda ash will further decrease. Although the inventory of glass manufacturers has decreased to a low level, the short - term driving effect on soda ash demand is limited and there are downward risks [2]

Core Viewpoint - The soda ash industry is facing challenges due to oversupply and weak demand, necessitating a shift from price competition to value competition through technological advancements and green manufacturing practices [1][4][5]. Group 1: Supply and Demand Dynamics - By 2025, the soda ash market is expected to experience a supply surplus and weak demand, with high inventory levels indicating a cyclical adjustment phase [2]. - Domestic soda ash production capacity is projected to exceed 40 million tons by 2024, with a production increase of 493.1 million tons year-on-year in the first three quarters of this year [2]. - The core downstream demand for soda ash comes from float glass, which accounts for 35%-40% of total demand, but new construction in the real estate sector has declined, limiting growth [2]. Group 2: Inventory Trends - Starting from March 2024, soda ash inventory rose from 400,000 tons to a peak of 1.9 million tons, stabilizing above 1.4 million tons [3]. - As of November 27, the total inventory of soda ash manufacturers was 1.409 million tons, with delivery warehouse inventory at 583,800 tons [3]. Group 3: Competitive Landscape - The industry is facing intensified homogenization, with some companies resorting to price competition, which has compressed overall profit margins [4]. - The price of heavy soda ash peaked at 3,681 yuan per ton in October 2021, but has since fluctuated between 1,218.57 and 1,344.29 yuan in the third quarter of this year [4]. - Natural soda ash is gaining market share due to its cost advantages, increasing from 5% in 2022 to 17% in 2025, positioning it favorably against other production methods [4]. Group 4: Path to Value Competition - The industry must transition from price competition to value competition, emphasizing technological and service upgrades to enhance competitiveness [5]. - There is a pressing need to develop high-value products for high-end sectors like renewable energy, which currently lack sufficient production capacity [5]. - Innovations in clean production methods and resource utilization are being prioritized, with companies exploring technologies such as using industrial waste salt for soda ash production [5]. Group 5: Collaborative Ecosystem and Global Expansion - Companies are shifting from independent operations to collaborative ecosystems, with industry leaders like China Salt Group leading initiatives to foster innovation through partnerships [6]. - Chinese soda ash production technology is being exported globally, exemplified by the launch of Indonesia's first soda ash project utilizing Chinese methods, contributing to the diversification of the global soda ash supply chain [6]. - The future of China's soda ash industry lies in enhancing high-end product supply, promoting green processes, and integrating value chains to establish a competitive edge in the global market [6].

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report - The overall sentiment in the commodity market was weak yesterday, and the prices of finished steel products continued to decline. The terminal demand remains weak, and the inventory pressure of hot-rolled coils is still prominent. Steel prices are expected to continue to fluctuate at the bottom, but attention should be paid to the winter storage price situation. Future attention should also be focused on the statements of the Federal Reserve and the Bank of Japan, which may affect the macro environment [2]. - The price of iron ore is expected to fluctuate widely. The overall inventory of iron ore is high, and there is no sign of effectively resolving the structural inventory contradiction. The spot still has certain support. However, due to the expected loose supply pattern of iron ore in 2026 and the lack of imagination on the demand side, there is still pressure for the price to decline periodically within the range, and the support for the weighted contract is expected to be around 750 yuan/ton [5]. - For manganese silicon and ferrosilicon, the future market trend will be led by the direction of the black metal sector and the issues of manganese ore for manganese silicon and electricity price increase for ferrosilicon. Particular attention should be paid to whether there are sudden situations in the manganese ore sector and their possible strong driving force on the market [9]. - The price of industrial silicon is expected to run weakly, with the support level at 8100 - 8300 yuan/ton. The supply and demand of industrial silicon are both weak, and the contradiction is not prominent. The recent low performance of coking coal futures and the decline of the polysilicon futures price have affected the overall sentiment of industrial silicon [12]. - The polysilicon market shows a tug - of - war between reality and expectation, and between the upstream and downstream of the industry. The price is expected to fluctuate widely within the range. Future attention should be paid to the progress of state - owned reserve procurement and the situation of warehouse receipt registration [14]. - For glass, in the absence of unexpected changes, a bearish view on the glass market is recommended. For soda ash, the market is expected to continue the weak and volatile trend in the short term, and a cautiously bearish view is maintained [17][19]. Summary by Related Catalogs Steel (Rebar and Hot - Rolled Coil) Market Information - Rebar: The closing price of the main contract was 3079 yuan/ton, down 44 yuan/ton (-1.40%) from the previous trading day. The registered warehouse receipts were 35,821 tons, a decrease of 10,455 tons compared to the previous day.

The spot prices in Lecong and Shanghai decreased by 40 yuan/ton and 30 yuan/ton respectively [1]. Strategy Viewpoints - Rebar: The production this week has significantly declined, and the inventory continues to be depleted, showing a neutral - to - stable overall performance. - Hot - rolled coil: The production has decreased, but the apparent demand remains neutral. It is difficult to deplete the inventory, and the social inventory is still at a relatively high level. The steel demand in the housing construction sector is under pressure, and future attention should be paid to the winter storage price [2]. Iron Ore Market Information - The main contract (I2605) closed at 757.50 yuan/ton, with a change of -0.39% (-3.00). The open interest changed by +12,385 lots to 441,800 lots. The weighted open interest was 905,300 lots. The spot price of PB powder at Qingdao Port was 784 yuan/wet ton, with a basis of 75.17 yuan/ton and a basis ratio of 9.03% [4]. Strategy Viewpoints - Supply: The overseas iron ore shipment volume increased slightly in the latest period. The shipment from Australia increased, mainly due to the rebound of Rio Tinto and FMG's shipments. The shipment from Brazil decreased, with a significant decline in Vale's shipments. The shipment from non - mainstream countries reached a high for the year, and the near - term arrival volume decreased month - on - month. - Demand: The average daily pig iron output was 232.3 million tons, a decrease of 2.38 million tons month - on - month. The number of blast furnaces under maintenance was more than those under复产, and the annual inspections increased with relatively long durations.

The overall data was marginally neutral after the decline in pig iron production, and the pressure on the raw material end was relatively limited. The overall inventory of iron ore is high, and there is no sign of effectively resolving the structural inventory contradiction, but the spot still has certain support [5]. Manganese Silicon and Ferrosilicon Market Information - Manganese silicon: The main contract (SM603) closed down 0.07% at 5732 yuan/ton. The spot price in Tianjin was 5720 yuan/ton, with a converted basis of 5910 yuan/ton, unchanged from the previous day, and a premium of 178 yuan/ton over the futures price [8]. - Ferrosilicon: The main contract (SF603) closed up 0.33% at 5462 yuan/ton. The spot price in Tianjin was 5600 yuan/ton, unchanged from the previous day, and a premium of 138 yuan/ton over the futures price [8]. Strategy Viewpoints - The supply - demand pattern of manganese silicon is not ideal, with a loose structure, high inventory, and a weak downstream building materials industry. The supply - demand of ferrosilicon is basically balanced. The future market trend will be led by the direction of the black metal sector and the issues of manganese ore for manganese silicon and electricity price increase for ferrosilicon. Particular attention should be paid to the manganese ore sector [9]. Industrial Silicon and Polysilicon Market Information - Industrial silicon: The main contract (SI2601) closed at 8340 yuan/ton, with a change of -3.86% (-335). The weighted open interest changed by +39,071 lots to 498,264 lots. The spot prices of 553 and 421 in East China decreased by 100 yuan/ton and 50 yuan/ton respectively [11]. - Polysilicon: The main contract (PS2601) closed at 55,610 yuan/ton, with a change of +1.95% (+1065). The weighted open interest changed by +12,302 lots to 270,926 lots. The average prices of N - type granular silicon, N - type dense material, and N - type re - feed material in the spot market were unchanged. The basis was -3310 yuan/ton. A new polysilicon platform company was registered on December 9, 2025 [13]. Strategy Viewpoints - Industrial silicon: The production in the southwest region is expected to decline in December due to the dry season, while the production in the northwest region is expected to be stable. The overall demand is slightly weak, and the price is expected to run weakly with support at 8100 - 8300 yuan/ton [12]. - Polysilicon: The production is expected to continue to decline in December, but the decline may be limited due to the capacity ramp - up in some northwest bases. The inventory accumulation pressure before the Spring Festival is difficult to relieve. The price is expected to fluctuate widely within the range, and attention should be paid to the progress of state - owned reserve procurement and warehouse receipt registration [14]. Glass and Soda Ash Market Information - Glass: The main contract closed at 984 yuan/ton, down 1.80% (-18). The sample enterprise's weekly inventory was 59.442 million cases, a decrease of 2.92 million cases (-4.68%).

The top 20 long - position holders reduced their positions by 30,481 lots, and the top 20 short - position holders reduced their positions by 31,328 lots [18]. Strategy Viewpoints - Glass: In November, several production lines in the domestic glass industry were shut down for maintenance. The real - estate industry still has downward pressure, and a bearish view on the glass market is recommended in the absence of unexpected changes [17]. - Soda ash: The overall supply pressure is still large, and the demand is relatively flat. The production enterprises mainly execute previous orders and have a strong mentality of stabilizing prices. The Alxa Phase II project is planned to be put into operation on December 11, which is expected to bring certain pressure to the market. The market is expected to continue the weak and volatile trend in the short term, and a cautiously bearish view is maintained [19].

Report Industry Investment Rating - The report gives a mid - term outlook of "sideways" for the entire black building materials sector, including steel, iron ore, scrap steel, coke, coking coal, glass, soda ash, ferrosilicon, and silicomanganese [7][8][9]. 2. Core Viewpoints of the Report - The Politburo meeting did not release any signals beyond expectations. Attention should be paid to the upcoming Central Economic Work Conference and the overseas interest - rate cut rhythm. The profitability of steel mills has improved recently, and it is expected that steel production will not decline significantly in the later period. The fundamentals are still under pressure after entering the off - season, and the steel futures market is running weakly. There is a seasonal weakening expectation for hot metal, and there is an expectation of an increase in Mongolian coal imports. The iron ore and coking coal markets were weak during the day session and showed signs of stabilization at night. The supply - demand surplus of glass and soda ash continues to suppress the futures prices [1]. - Overall, the fundamentals in the off - season are not good. Without any signals beyond expectations from the Politburo meeting, it is expected that the sector will still face downward adjustment pressure in the short term [6]. 3. Summary by Related Catalogs 3.1 Iron Element - Hot metal production has decreased significantly, downstream demand has declined, and steel mills are conducting annual maintenance. Although the profitability of steel mills has slightly improved, the release of restocking demand is still slow. Overseas mine shipments have increased slightly month - on - month, with Australian shipments rebounding, Brazilian shipments rising and then falling, and non - mainstream shipments increasing significantly. The arrivals this period have decreased significantly month - on - month, but port inventories have continued to accumulate, and steel mill inventories have increased month - on - month, with overall inventory accumulation pressure. The fundamental contradictions of scrap steel are limited. After the spot price has fallen, its cost - effectiveness has recovered. The profits of electric arc furnaces are acceptable, and the demand for scrap steel from long - and short - process steel enterprises is still supported. It is expected that the scrap steel price will fluctuate [2]. 3.2 Carbon Element - The cost support for coke has weakened, and there is a strong expectation of further price cuts. However, there is still an expectation of winter restocking for raw materials in mid - to late December, and the fundamentals still provide support. Currently, the futures valuation is too low, and there is insufficient driving force for a further significant decline. It is expected to fluctuate following coking coal. It will take time to reverse the pessimistic sentiment in the coking coal market. The downstream winter restocking that will start in mid - to late December may gradually improve the fundamentals and market sentiment. Based on the expectation that the weakening of the coking coal supply - demand pattern is limited, the low - level valuation of the futures market is expected to gradually recover [2]. 3.3 Alloys - The firm cost supports the price, but the market supply - demand is in a loose state, the cost transfer is not smooth, and there is insufficient driving force for the futures price to rise. It is expected that the ferrosilicon manganese futures price will mainly fluctuate at a low level. The high - level cost supports the bottom of the ferrosilicon price, but the market has weak supply and demand, and there are still difficulties in destocking. Caution should be exercised regarding the upward space of the futures price. It is expected that the ferrosilicon futures price will mainly fluctuate at a low level [2]. 3.4 Glass and Soda Ash - There are still expectations of supply disruptions, but the inventories of middle - and downstream enterprises are moderately high. From a fundamental perspective, the current supply - demand is still in surplus. If there is no more cold - repair before the end of the year, the high inventory will always suppress the price, and it is expected to fluctuate weakly; otherwise, the price will rise. The soda ash industry price is approaching the cost, and the bottom support is relatively obvious. Recently, the cold - repair of glass has further increased. Although the overall supply - demand is still in surplus, it is expected to fluctuate in the short term. In the long run, the supply - surplus pattern will further intensify, and the price center will still decline, promoting capacity reduction [3][6][12]. 3.5 Specific Products 3.5.1 Steel - The macro support is limited, and the futures market continues to be weak. The spot market transactions are generally weak. Near the end of the year, steel mill maintenance has increased, iron and steel production has declined from a high level, and the demand for building materials has weakened significantly. The overall steel inventory continues to decline, but the current inventory level is still higher than the same period last year. The Politburo meeting did not release any signals beyond expectations. It is expected that the steel production will not decline significantly in the later period, and the futures market will run weakly [7]. 3.5.2 Iron Ore - The market sentiment is average, and the price fluctuates. The overseas mine shipments have increased slightly month - on - month, and the arrivals have decreased significantly this period. The demand has declined, and the inventory has accumulated. It is expected that the hot metal output will continue to decline seasonally, and the short - term iron ore price is expected to fluctuate [8]. 3.5.3 Scrap Steel - The arrivals have increased slightly, and the price fluctuates. The supply has increased, and the demand from electric arc furnaces and blast furnaces has changed. The inventory of steel enterprises has increased slightly. The scrap steel fundamentals have limited contradictions, and it is expected that the price will fluctuate [9]. 3.5.4 Coke - The futures market has stabilized at a low level, and there is still an expectation of price cuts in the spot market. The supply is affected by raw material prices and environmental protection, and the demand has declined seasonally. The inventory has slightly accumulated. The cost support has weakened, but there is an expectation of winter restocking. It is expected to fluctuate following coking coal [10]. 3.5.5 Coking Coal - The auction transactions have improved slightly, and the futures market is still running weakly. The domestic supply is at a low level, and the imports have recovered. The demand has declined, and the inventory has accumulated. The pessimistic sentiment needs time to reverse, and the low - level valuation of the futures market is expected to gradually recover [11]. 3.5.6 Glass - The futures and spot transactions have improved, but the spot market is still weak. The supply is expected to decline in the long run but is difficult to have a large - scale cold - repair in the short term. The demand is weak year - on - year, and the high inventory of middle - stream enterprises suppresses the valuation. If there is no further cold - repair, the price may have a downward pressure [12]. 3.5.7 Soda Ash - The warehouse receipts are still increasing, and the price fluctuates at a low level. The supply is expected to increase, and the demand is weak. The industry is in the bottom - clearing stage. It is expected to fluctuate in the short term and decline in the long run [12][14]. 3.5.8 Ferrosilicon Manganese - The cost price is firm, and the decline of the futures price is limited. The cost support is strong, the demand from steel mills is weak in the off - season, and the supply is affected by production cuts. It is expected that the futures price will mainly fluctuate at a low level [14]. 3.5.9 Ferrosilicon - The cost reduction space is limited, and the futures price runs at a low level. The cost is at a high level, the demand from steel mills and metal magnesium is weak, and the supply has decreased slightly. It is expected that the futures price will mainly fluctuate at a low level [16].
