Report Industry Investment Rating - Not provided in the content Core Views - The current soda ash market is in a weak equilibrium pattern of "high supply, low demand, neutral inventory, and strong cost." The reduction of heavy soda ash inventory brings short - term sentiment repair, and the resilience of light soda ash demand provides bottom support. However, there is no obvious increase in the terminal glass industry, lacking trend - driving forces. The futures price forms technical support in the range of 1,150 - 1,180 yuan/ton, and may continue a volatile and slightly stronger trend in the short term, but still faces over - capacity pressure in the medium term [3]. - As of January 22, the number of registered soda ash futures warehouse receipts dropped sharply to 70, a significant decrease from 2,432 on January 19, and the effective forecast rose to 2,747, indicating an enhanced market delivery intention. Some short - sellers shifted positions or prepared for delivery, and the short - term liquidity pressure eased. The main contract SA2605 closed at 1,198 yuan/ton on January 23, and technically approached the key support area of 1,150 - 1,160 yuan/ton. The basis performance: the spot price of heavy soda ash in North China is about 1,250 yuan/ton, the closing price of SA2605 is 1,185 yuan/ton, the basis narrowed to about 65 yuan/ton, and the futures - spot discount was repaired, reflecting the market's expectation of stable spot prices [3]. Summary by Relevant Catalogs Market Overview - This week, the fundamentals of the soda ash market remained under pressure, featuring high - level supply, slight inventory reduction, structural differentiation in demand, enhanced cost support but price pressure. The futures price formed technical support in the range of 1,150 - 1,180 yuan/ton, and the short - term downward space was limited due to the cost bottom line and the structural demand for light soda ash [3]. Supply - The operating rate remained at a high level, and production increased steadily. This week, the overall operating rate of the soda ash industry remained above 86%. As of January 22, the national comprehensive operating rate of soda ash was 86.42%, among which the operating rate of the ammonia - soda process was 87.69% and that of the combined - soda process was 77.99%, basically the same as the previous week, indicating stable capacity utilization and an undiminished pace of new capacity release, with continuous pressure on the supply side [3]. Demand - Heavy soda ash was under pressure, while light soda ash still showed resilience. During the week, the daily melting volume of float glass was 150,700 tons and that of photovoltaic glass was 87,200 tons. Next week, a 900 - ton production line of float glass is planned to resume production and ignite. Affected by the stable daily melting volume of float glass and the lack of obvious recovery in the capacity utilization rate of photovoltaic glass, the rigid demand for heavy soda ash remained weak. However, recently, some enterprises carried out phased replenishment due to pre - holiday stocking and cold - repair expectations, driving a significant decline in heavy soda ash inventory. The operating rate of the lithium carbonate industry remained above 87%, providing continuous support for light soda ash [3]. Inventory - This week, the inventory of soda ash continued the downward trend, but the pace slowed down. As of January 22, the total inventory of national soda ash manufacturers was 1.5212 million tons, a decrease of 23,000 tons or 1.49% from 1.5442 million tons on January 19, showing a second consecutive week - on - week decline. The inventory of heavy soda ash decreased from 721,600 tons to 696,700 tons, a decrease of 24,900 tons during the week, reflecting the phased replenishment of the downstream glass industry [3]. Profit - The production cost of soda ash remained at a high level, and the industry as a whole was in a deep - loss state. The price of steam coal fluctuated upward, and combined with the stable cost of rock salt, the production cost support was enhanced. However, the long - term losses in the industry inhibited the willingness to actively reduce production, and the cost line became an important support for the price decline. The theoretical profit of the ammonia - soda process was still negative, and the profit of the combined - soda process was also at a low level, with the industry as a whole deeply in the red [3].

Report Summary 1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints - The soda ash market is likely to maintain a weak and volatile pattern in the short term due to rising production, weakening demand, and insufficient downstream inventory reduction willingness, along with the long - standing core contradictions in the industry remaining unresolved. The glass market is also expected to show a weak and volatile trend in the short term, with supply contraction being the core price - supporting factor, but facing challenges from weak downstream real - estate data and the cancellation of export tax - rebate policies [8][9] 3. Summary by Directory 3.1 Soda Ash and Glass Market Review and Operation Suggestions - **Soda Ash**: On January 15, the main contract SA605 of soda ash slightly declined, closing at 1193 yuan/ton, down 25 yuan/ton or 2.05% from the previous day, with an intraday increase of 30,978 lots. The overall supply - demand pattern shows rising production, weakening demand, and inventory is expected to face continuous accumulation pressure. The downstream float glass industry is still weak, and the long - standing core contradictions in the industry remain unresolved. If the export scale does not expand significantly or the elimination of backward production capacity is slower than expected, the supply - demand pattern is not optimistic. In the short term, it will likely maintain a weak and volatile pattern [7][8] - **Glass**: On January 15, the main contract FG2605 of glass futures was weak and volatile, rising during the day and then falling. The glass production line is generally in a loss state, and there is still an expectation of cold repair before the festival, so the supply is expected to further narrow. The overall inventory base is still high. In the short term, supply contraction will support prices, but downstream real - estate data continues to decline year - on - year, and the cancellation of export tax - rebate policies squeezes profit margins. Before substantial benefits such as capacity clearance appear, it is expected to maintain a weak and volatile trend in the short term [9] 3.2 Data Overview - The report presents multiple data charts, including the price trends of active contracts for soda ash and glass, weekly production and enterprise inventory of soda ash, the market price of heavy soda ash in Central China, and the production volume of flat glass, etc., with data sources from Wind, iFind, and the research and development department of Jianxin Futures [12][13][14]

Report Information - Report Name: Soda Ash and Glass Daily Report [1] - Date: January 9, 2026 [2] Industry Investment Rating - Not provided. Core Views - Soda ash supply increased and inventory accumulated as of January 8, maintaining a weak pattern. The short - term is expected to be volatile and slightly stronger due to macro sentiment and other factors, but the long - term supply - demand contradiction remains unsolved [8][9]. - Glass futures' main contract FG2605 continued to rise on January 8, 2025. Short - term supply contraction may support prices, but high inventory restricts the market, and the upward trend is slow [10][11]. Summary by Directory 1. Soda Ash and Glass Market Review and Operation Suggestions Soda Ash - Supply: As of the week of January 8, the weekly output rose to 753,600 tons, a year - high, with a month - on - month increase of 8.11%. The equipment operation is stable with no maintenance plan [8]. - Demand: This week, the total shipment volume of Chinese soda ash enterprises decreased to 589,200 tons, a month - on - month decrease of 18.99%. The downstream float glass daily melting volume decreased by 300 tons to 151,500 tons, while the photovoltaic glass daily melting volume of 88,500 tons was relatively stable [8]. - Inventory: Affected by logistics during the festival, the factory inventory increased to 1.5727 million tons [8]. - Policy: The Shanxi differential electricity price policy strengthened the expectation of capacity clearance and "anti - involution" policies, accelerating the clearance of ammonia - alkali plants [8][9]. - Outlook: The short - term is expected to be volatile and slightly stronger, but the long - term supply - demand pattern remains unoptimistic without significant export expansion or backward capacity clearance [9]. Glass - Market: On January 8, 2025, the main contract FG2605 continued to rise. The market shipment was good, with obvious inventory reduction in some areas, and prices were boosted by market sentiment [10][11]. - Supply: There is an expectation of supply reduction. The overall inventory is high with obvious regional differentiation [11]. - Outlook: Short - term supply contraction may support the price, but high inventory restricts the market. The upward trend is slow, and there is an expectation of rebound and decline before substantial positive factors appear [11]. 2. Data Overview - The report provides multiple data charts, including the price trends of soda ash and glass active contracts, soda ash weekly production, soda ash enterprise inventory, central China heavy soda market price, and flat glass production, with data from Wind and iFind [13][18][20]

1. Report Industry Investment Rating - Not provided in the report 2. Core Views of the Report - The soda ash futures market is in a volatile stage, with a balanced supply and demand situation, high inventory, and weak downstream demand suppressing prices, while cost support limits the downside. The glass futures market is in a downward trend, with a supply - demand imbalance, high inventory, and a weak short - term outlook. [8][32] 3. Summary by Directory 3.1 Soda Ash Futures 3.1.1 Mid - line Market Analysis - Mid - line trend: The soda ash futures are in a volatile phase. - Trend logic: The domestic soda ash market was stable last week, with prices in some regions slightly increasing. Supply recovered as maintenance facilities resumed operation, and demand was divided (light soda ash was in short supply in some areas, while heavy soda ash was weak due to the decline in the glass industry's operation rate). The cost and pending orders supported the price. The futures price was volatile at a low level, and the supply - demand pattern was loose. - Strategy suggestion: It is recommended to wait and see. [8] 3.1.2 Variety Trading Strategy - Last week's strategy review: The domestic soda ash market was stable, with light soda ash demand being stable and heavy soda ash being weak. Supply decreased slightly due to maintenance but was generally sufficient. The market was in a game between weak reality and strong cost, and it was expected that SA2601 would operate in the range of 1100 - 1250. - This week's strategy suggestion: The soda ash spot market was stable last week, with prices in some regions slightly increasing. Supply gradually recovered, demand was divided, and prices were stable under cost and order support. The futures market was volatile at a low level, and it was expected that SA2601 would operate in the range of 1100 - 1250. [11][12] 3.1.3 Relevant Data - Relevant data includes China's weekly soda ash production, operating rate, light and heavy soda ash inventory, basis (daily), and the production cost of the ammonia - soda process in North China (weekly). The variety diagnosis shows that the main force is slightly bearish, the capital is basically stable, and the risk of a market reversal is high. [13][17][24] 3.2 Glass Futures 3.2.1 Mid - line Market Analysis - Mid - line trend: The glass is in a volatile downward trend. - Trend logic: The domestic float glass market declined last week, with prices in various regions dropping by 20 - 50 yuan/ton. Supply was abundant, downstream demand was weak, enterprises increased their inventory - clearing pressure, and the overall inventory was in an accumulating trend. The futures price continued to hit new lows. - Strategy suggestion: It is recommended to stay in an empty position and wait and see. [32] 3.2.2 Variety Trading Strategy - Last week's strategy review: The domestic float glass market was weak, with prices stable or decreasing. Supply was sufficient, but downstream orders were limited. The cost provided support, but the market lacked positive factors, and the futures market was in a weak and volatile trend. - This week's strategy suggestion: The float glass market was weak last week, with spot prices generally falling. Supply was abundant, demand was weak, and inventory pressure remained. The futures market was in a downward trend, and it was expected to maintain a weak and volatile trend. [35][36] 3.2.3 Relevant Data - Relevant data includes China's weekly float glass production, operating rate, production cost and profit of the float process using natural gas as fuel, basis (daily), and end - of - week inventory. The variety diagnosis shows that the main force is strongly bearish, the capital outflow is large, and the risk of a market reversal is extremely high. [37][42][49]

Report Information - Report Title: Soda Ash and Glass Daily Report [1] - Report Date: November 6, 2025 [2] Industry Investment Rating - Not provided Core Views - For soda ash, the supply remains high, the开工 rate declines slightly, and inventory decreases marginally. The downstream market mainly replenishes inventory at low prices, and the glass market continues to face weak supply and demand. With the arrival of winter, there is insufficient driving force in the supply - demand aspect, and the pattern of oversupply may continue. The market is expected to fluctuate weakly [8]. - For glass, although the production limit in Shahe has been implemented, the actual situation is below expectations. Coupled with the arrival of the off - season, there is no new driving force in the market. The short - term bullish sentiment from the Shahe production halt has been digested. The price will mainly fluctuate in the near term, and if there is no new macro - level positive news, the downward trend is difficult to reverse [9]. Summary by Directory 1. Soda Ash and Glass Market Review and Operation Suggestions Soda Ash - **Market Data**: On November 5, the main soda ash futures contract SA601 fluctuated strongly. The closing price was 1,195 yuan/ton, up 1 yuan/ton or 0.08%, with a daily reduction of 36,997 lots [7]. - **Fundamentals**: The enterprise production and sales tend to balance, and inventory fluctuates little. The weekly production increased by 17,000 tons to 757,600 tons, remaining at a high level. The soda ash plant maintenance is at a high level in the same period. In late October, the shipments of Chinese soda ash enterprises continued to recover, with a total shipment of 757,700 tons, a month - on - month increase of 2.53%. The production of float glass remained stable, but four coal - fired production lines in Shahe are planned to be shut down for cold repair, and the production of photovoltaic glass remained unchanged. The alkali plant inventory slightly decreased to 1.702 million tons, at a relatively low level in the past six months [8]. Glass - **Market Data**: The four coal - fired production lines in Shahe will be shut down in the short term. The photovoltaic glass market is in a weak balance, and the overall glass supply is at a high level for the year. After the holiday, the factory inventory remains high, and the inventory days have continued to rise. The real estate market has not shown a stabilizing trend, the completion data is weak, and the recovery of float glass demand may not be sustainable [9]. 2. Data Overview - The report provides multiple data charts, including the price trends of soda ash and glass active contracts, soda ash weekly production, soda ash enterprise inventory, central China heavy soda market price, and flat glass production [11][12][15]

The market will fluctuate around demand, and the overall de - stocking trend remains unchanged [2].

Report Industry Investment Ratings No relevant information provided. Core Views Natural Rubber - Short - term macro - atmosphere improves, fundamentals improve, and rubber prices rebound. Follow - up attention should be paid to raw material output in the peak production season of main producing areas and macro - level changes. If raw material supply is smooth, there is further downward space; if not, rubber prices are expected to run around 15,000 - 15,500 yuan/ton [1]. Logs - Currently, there is no obvious driving force in the log supply - demand situation. The 01 contract is relatively strong. New rounds of foreign quotes have increased, and subsequent port fees are expected to rise, providing strong cost support. During the seasonal peak season, there is some support below the futures price, and the 01 contract may be strong [4]. Industrial Silicon - Some industrial silicon spot prices have decreased by 50 yuan/ton, and futures have fluctuated and closed down by 20 yuan/ton to 8,485 yuan/ton. In September, exports decreased by 8% month - on - month to 70,200 tons, but still increased year - on - year. In October, industrial silicon supply has increased significantly, with inventory risks, and prices will still be under pressure. Although some enterprises in the southwest region have reduced production, the impact on output is small. Considering the possible increase in raw material costs, the price center of gravity is expected to move up in the future. It is expected to fluctuate at a low level, with the main price range between 8,000 - 9,000 yuan/ton [5]. Polysilicon - The polysilicon market is relatively stable. On one hand, pay attention to policy implementation and production control; on the other hand, pay attention to whether there is an increase in orders on the demand side. Currently, it is mainly in a high - level shock. In November, production reduction in the southwest region during the dry season will relieve the pressure of production growth and support prices. Be vigilant against the risk of inventory accumulation due to insufficient demand [6]. Glass and Soda Ash - **Soda Ash**: Driven by the strengthening of coking coal - related varieties, the soda ash futures price has rebounded slightly, but the fundamentals have not changed significantly. Previously, soda ash has been weak, with manufacturers' inventories and mid - stream delivery inventories increasing. The supply is in excess. In the medium - term, downstream demand is expected to remain at the previous rigid - demand level. The overall supply - demand pattern is bearish, and the strategy of short - selling on rebounds can be continued [7]. - **Glass**: Driven by the strengthening of coking coal - related varieties, the glass futures price has rebounded slightly, but the fundamentals have not changed significantly. Manufacturers' sales are average, and prices are continuously decreasing. The trading sentiment reflects that the peak season is not prosperous and the supply is in excess. In the long - term, the real - estate cycle is at the bottom, and capacity clearance is needed to solve the over - supply problem [7].
