Report Summary 1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - SH2603 fluctuated narrowly, closing at 1,958 yuan/ton. This week, the operating loads in various regions decreased to varying degrees, and the national average capacity utilization rate of caustic soda decreased slightly but remained at a high level [2]. - Affected by the maintenance of some domestic alumina plants, the alumina operating rate decreased slightly. The load of some viscose staple fiber units was slightly adjusted, and the operating rate decreased slightly. Printing and dyeing enterprises in the Jiangsu and Zhejiang regions have fully taken holidays and stopped production, and the printing and dyeing operating rate has dropped to 0% [2]. - Some downstream enterprises in East and South China actively replenished their stocks this week, and some production enterprises in North and Northwest China cleared their inventories before the Spring Festival. The inventory of liquid caustic soda plants across the country decreased month - on - month, but the inventory was still at a relatively high level compared to the same period [2]. - Affected by the weak price of liquid chlorine, Shandong's chlor - alkali profit showed a downward trend this week, and the theoretical loss of enterprises deepened. With the decline of chlor - alkali profit, the market price of 32% caustic soda in Shandong has gradually stopped falling and rebounded. However, in the short term, the caustic soda price is still suppressed by high domestic supply and weak demand. Sustained rebound requires the support of production cuts by chlor - alkali plants in the future [2]. - After the Spring Festival, as the delivery month of the 03 contract approaches, the price rebound space is limited. The daily range of SH2603 is expected to be around 1,930 - 2,000. The 05 contract trades on the expectation of chlor - alkali plant maintenance, and the price has relatively high upward elasticity. The daily range of SH2605 is expected to be around 2,130 - 2,200 [2] 3.

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Views of the Report - The overall supply - demand pattern of PVC is weak. After April, the export is expected to decline significantly, and the supply - demand relationship of subsequent contracts will be further relaxed. The supply of domestic PVC is abundant, the downstream starts are generally flat, the inventory is increasing, and the cost - side profit is still low year - on - year. The supply - demand of caustic soda is also weak, with inventory accumulation in Shandong and Jiangsu, high overall supply - side start, and general downstream receiving sentiment [3]. Group 3: Summary by Related Catalogs PVC Market News and Important Data - Futures price and basis: The closing price of the PVC main contract is 4940 yuan/ton (+43), the East China basis is - 320 yuan/ton (- 43), and the South China basis is - 310 yuan/ton (- 43). - Spot price: The East China calcium carbide method is quoted at 4620 yuan/ton (+0), and the South China calcium carbide method is quoted at 4630 yuan/ton (+0). - Upstream production profit: The semi - coke price is 750 yuan/ton (+0), the calcium carbide price is 2805 yuan/ton (+25), the calcium carbide profit is - 85 yuan/ton (+25), the PVC calcium carbide method production gross profit is - 634 yuan/ton (+80), the PVC ethylene method production gross profit is - 192 yuan/ton (+87), and the PVC export profit is - 18.2 US dollars/ton (+3.8). - Inventory and start - up: The in - factory inventory of PVC is 32.8 tons (+1.9), the social inventory is 54.6 tons (+2.1), the calcium carbide method start - up rate is 80.23% (+2.00%), the ethylene method start - up rate is 75.69% (+0.41%), and the overall start - up rate is 78.85% (+1.51%). - Downstream order situation: The pre - sales volume of production enterprises is 90.9 tons (+9.4) [1]. Market Analysis - The export tax rebate for PVC will be cancelled from April 1st, and there may be a situation of rushing to export. The export orders still have resilience, which is beneficial to the contracts before April. The overall supply - demand pattern of the PVC market is weak. The supply is abundant, the downstream start is generally flat, and there is an expectation of further decline in the future. The inventory is increasing slightly and is at a high level year - on - year. The cost - side profit is still low year - on - year, and the pressure of hedging on the disk still exists. After April, the export is expected to decline significantly, and the supply - demand relationship of subsequent contracts will be further relaxed [3]. Strategy - Unilateral: Oscillation - Inter - delivery: Go long V03 - 05 at low prices - Inter - commodity: None [4] Caustic Soda Market News and Important Data - Futures price and basis: The closing price of the SH main contract is 2180 yuan/ton (- 44), and the basis of 32% liquid caustic soda in Shandong is - 30 yuan/ton (+44). - Spot price: The price of 32% liquid caustic soda in Shandong is 688 yuan/ton (+0), and the price of 50% liquid caustic soda in Shandong is 1080 yuan/ton (+0). - Upstream production profit: The single - variety profit of caustic soda in Shandong is 1125 yuan/ton (+0), the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) is 557.8 yuan/ton (+40.0), the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) is - 239.20 yuan/ton (- 35.00), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) is 554.50 yuan/ton (- 50.00). - Inventory and start - up: The factory inventory of liquid caustic soda is 49.51 tons (+0.94), the factory inventory of flake caustic soda is 3.08 tons (+0.06), and the start - up rate of caustic soda is 86.80% (+0.40%). - Downstream start - up: The start - up rate of alumina is 85.74% (+1.07%), the start - up rate of printing and dyeing in East China is 60.09% (- 0.72%), and the start - up rate of viscose staple fiber is 88.43% (+3.38%) [1][2]. Market Analysis - The spot price of caustic soda is stable with a slight decline, and is weak due to the influence of low - price warehouse receipts. The macro - sentiment has subsided, and the disk has oscillated and corrected. The draft for soliciting opinions on differential electricity prices in Shaanxi has raised the cost expectation, but the impact is small. The supply - demand of caustic soda is weak, with inventory accumulation in Shandong and Jiangsu. The overall supply - side start is at a high level, the demand - side receiving sentiment is general, and the export orders continue to be sluggish [3]. Strategy - Unilateral: Cautiously bearish - Inter - delivery: Go short SH03 - 05 at high prices - Inter - commodity: None [4][5]

Core Viewpoint - The caustic soda futures market is experiencing a significant upward trend, with the main contract rising by 4.43% to 2263.0 CNY/ton as of January 7 [1]. Market Summary - On January 6, the price of 32% liquid caustic soda in the Zhejiang market ranged from 980 to 1020 CNY/ton, while the price for 48% ion membrane caustic soda was between 1450 and 1550 CNY/ton [2]. - The top 20 futures companies held a total of 155,500 long positions and 170,100 short positions, resulting in a long-to-short ratio of 0.91. The net position increased by 6,460 contracts to -14,500 contracts compared to the previous day [2]. Supply and Demand Dynamics - Recent recovery of certain facilities in North China, East China, and South China has led to an increase in the national average capacity utilization rate for caustic soda [3]. - Newhu Futures indicates that high operating rates on the supply side are expected to continue, with additional capacity creating further supply pressure. Although profits have been compressed, companies can still maintain production, supported by good demand for liquid chlorine. However, the demand for caustic soda is expected to remain weak due to high production and inventory levels in alumina, leading to anticipated production cuts in Shanxi and Henan [4]. - Huatai Futures notes that with fewer planned maintenance activities in January, supply pressure is unlikely to ease. The non-aluminum downstream sector is entering a seasonal decline, and the demand for caustic soda is expected to contract due to the impact of anti-competitive policies on alumina [4].

Report Industry Investment Rating - Not provided in the document Core Viewpoints - The caustic soda market is currently in a situation of supply contraction, weak demand, and improving profits. Liquid caustic soda is expected to stabilize in the short term, and prices in Shandong may rise slightly. The futures market is expected to remain volatile and weak in the short term, and attention should be paid to the sustainability of the rebound in Shandong spot prices and the cost - side logic transformation caused by liquid chlorine price fluctuations [4]. - For trading strategies, a unilateral long position in caustic soda is recommended as prices may rise steadily; for arbitrage and options, it is advisable to wait and see [5]. Summary by Directory 1. Comprehensive Analysis and Trading Strategy Comprehensive Analysis - Supply side: This week, the number of caustic soda plant overhauls increased. The national sample enterprise operating load rate dropped to 88.47% (a 1.37% week - on - week decrease), and the output of 100% equivalent caustic soda decreased to 856,300 tons (a 1.52% week - on - week decrease), slightly alleviating the short - term supply pressure [4]. - Demand side: The operating rate of the core downstream alumina industry dropped to 80.29% (a 1.08% week - on - week decrease), weakening the support for caustic soda. Non - aluminum downstream industries such as viscose staple fiber saw a slight increase in operating rates, but overall procurement remained at a just - in - time level, and most purchases were made at low prices, resulting in a lukewarm market [4]. - Inventory side: There was a significant differentiation in inventory. For liquid caustic soda, the overall sample inventory in East China decreased by 10.25%, but the factory inventory in Shandong increased by 6.01%. For flake caustic soda, due to shipping issues and hoarding by traders, the social inventory in East China surged by 55.56%, and traders faced greater pressure to sell [4]. - Profit side: The comprehensive profit of chlor - alkali (ECU) was significantly repaired due to the sharp rebound in liquid chlorine prices, despite the decline in caustic soda prices. The profit of enterprises with self - owned power plants in Shandong increased by 49.18% to 160.2 yuan/ton, which may support manufacturers' willingness to maintain production [4]. Trading Strategy - Unilateral: Caustic soda prices may rise steadily [5]. - Arbitrage: Wait and see [5]. - Options: Wait and see [5]. 2. Core Logic Analysis - In Shandong, the delivery volume of liquid caustic soda to large alumina plants was at a high level, and prices continued to decline. From November 14 to December 6, the purchase price of 32% ion - exchange membrane caustic soda by major alumina manufacturers in Shandong decreased from 730 yuan/ton to 675 yuan/ton [7][9]. - As of December 18, 2025, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons or more in China was 464,700 tons (wet tons), a 1.66% week - on - week increase and a 52.34% year - on - year increase. The capacity utilization ratio of national liquid caustic soda sample enterprises was 29.41%, a 0.41% week - on - week increase. Different regions showed different inventory trends [11]. - The supply contradiction in the alumina spot market became more prominent. Although the operating capacity of alumina was basically stable this week, the inventory of alumina at the electrolytic aluminum end continued to rise. The supply contradiction is expected to continue to be reflected in limited spot transactions [15][18]. - This week, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons or more was 84.7%, a 1.5% week - on - week decrease.

Core Insights - The domestic liquid caustic soda market is experiencing weak transaction activity, with prices for 32% and 50% liquid caustic soda declining in various regions due to low demand from downstream industries and traders [1][2] - The overall operating rate of major sample enterprises in the country has decreased slightly, indicating a reduction in production activity [1][2] - Inventory levels for 32% liquid caustic soda have increased in several regions, reflecting a lack of purchasing enthusiasm from downstream buyers [2] Price Trends - Prices for 32% liquid caustic soda in Shandong are currently between 680-775 RMB/ton, while 50% liquid caustic soda is priced at 1150-1170 RMB/ton [1] - The price of liquid caustic soda is expected to continue to trend weakly due to ongoing supply pressures and a lack of significant demand [2] Inventory Levels - As of November 26, the inventory of 32% liquid caustic soda in East China has risen to 261,400 tons, a 6.04% increase from the previous week [2] - In Shandong, the inventory for 32% liquid caustic soda has increased by 9.19% to 124,800 tons, attributed to high operating rates and low unloading efficiency from aluminum oxide enterprises [2] Market Outlook - The caustic soda industry is facing ongoing supply and demand pressures, with high production levels and elevated inventories leading to a weak price outlook [2] - The traditional demand off-season is persisting, and there is no significant boost from exports, suggesting that prices will likely remain weak in the near term [2]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report Caustic Soda - The caustic soda industry still faces certain supply - demand pressures. Shandong chlor - alkali enterprises are operating at a high level, and there are still vehicle - queuing situations at major downstream enterprises. Enterprises have high inventories, and there are no short - term positive factors. The price is expected to be weak in the next week. In the East China region, supply will remain abundant, the traditional off - season for demand will continue, and exports are not significantly boosted. It is estimated that the price in East China will continue to decline. Overall, the demand side provides weak support, and there are still long - term supply - demand pressures. The price of caustic soda is expected to run weakly [2]. - Futures strategy advice: Adopt a bearish approach. - Options strategy advice: Stay on the sidelines. PVC - The supply pressure will not ease next week, and the operating rate still has room for improvement. The operating rate of pipe and profile products remains low, while the soft products will remain in high demand, and export orders may increase slightly. The cost - side support is expected to continue to strengthen, and the PVC market is expected to continue to operate in a range. From November to January of the following year is the traditional off - season for demand. As outdoor construction in the north gradually decreases in winter, the overall real - estate demand reduction still has a negative impact. In terms of exports, the inventory in the Indian region is currently at a high level, the purchasing enthusiasm is average, the international market competition is fierce, and the export boost is limited. The overall demand side provides weak support for PVC, the supply - demand situation remains in an oversupply pattern, the price is not optimistic, and although the absolute price is low, it is difficult to form a continuous upward drive. It is expected to continue the bottom - weakening pattern [3]. - Futures strategy advice: Treat rebounds with a bearish attitude. - Options strategy advice: Stay on the sidelines. Summary by Relevant Catalogs Caustic Soda Market Performance - The caustic soda market has shown various trends due to factors such as macro - environment changes, supply - demand relationships, and cost fluctuations. For example, the 8 - month contract repaired the basis, and the market accelerated its decline. The spot market was in a game, and there were concerns about the marginal weakening under the subsequent supply recovery, with the downstream demand being stable [6]. Supply - As of Thursday this week, the weekly weighted average operating load rate of sample enterprises in major regions across the country was 89.86%, a 0.17 - percentage - point increase from 89.69% last week. There were few chlor - alkali device overhauls this week, and the operating load rate increased slightly. In Shandong, it was 91.45%, a decrease of 0.21% [25]. - On December 3rd, the inventory of 32% liquid caustic soda of expanded sample enterprises in East China was 253,150 tons, a 3.16% decrease from 261,400 tons on November 26th. The inventory in Shandong decreased slightly due to some factories delivering goods to downstream, and the overall inventory in East China decreased. The inventory of 32% liquid caustic soda of expanded sample enterprises in Shandong was 120,400 tons, a 3.53% decrease from 124,800 tons on November 26th [25]. Device Dynamics - There are multiple caustic soda production enterprises with various overhaul situations, including long - term shutdowns, current overhauls, and future planned overhauls. For example, Wuhai Chemical in the Northwest has been shut down since July 22, 2023, and the start - up time is undetermined; Zhejiang Juhua in the East China has been operating at half - load since October 11, continuing until January 1, 2026 [26]. Downstream Demand - Alumina: From the end of 2024 to 2025, the planned alumina production capacity to be put into operation is 1.23 billion tons (including 200 million tons of replacement). It is estimated that the annual production capacity growth rate will be around 10%. The estimated annual alumina production in 2025 will be over 88 million tons, with a production growth rate of around 6%. The new alumina demand is estimated to require an additional 400,000 - 550,000 tons of caustic soda per year, and the total demand increase for caustic soda is around 800,000 tons, with a relatively concentrated demand increase of 150,000 tons from April to June [30]. - Currently, the domestic alumina futures and spot prices are both poor, market confidence has not been significantly restored, and it is expected that the price will maintain a weak adjustment trend, with the price operating in the range of 2,700 - 2,900 yuan/ton [34]. - Non - aluminum downstream industries: The textile operating rate has declined, while the viscose staple fiber operating rate has increased [49]. Export - In October, caustic soda exports weakened, and the estimated export profit declined [56]. PVC Market Performance - The PVC futures market has been affected by factors such as supply - demand relationships, macro - sentiment, and cost. For example, due to the lack of positive supply - demand drivers and a poor commodity atmosphere, the futures price has continued to decline [63]. Profit - The industry profit of PVC has continued to deteriorate, and the profits of various production methods such as the calcium carbide method and ethylene method in East China and the northwest region have shown different degrees of decline [69]. Supply - This week, the operating load rate of the domestic PVC powder industry increased slightly. Only one enterprise had a temporary shutdown this week, and the previously overhauled enterprises gradually resumed production, resulting in a decrease in overhaul losses. The overall operating load rate of PVC powder this week was 79.01%, a 0.16 - percentage - point increase from last week; among them, the operating load rate of calcium carbide - based PVC powder was 82.09%, a 0.12 - percentage - point decrease; and the operating load rate of ethylene - based PVC powder was 71.92%, a 0.8 - percentage - point increase [85]. Device Dynamics - There are long - term shutdowns, current overhauls, and future planned overhauls of PVC production enterprises. For example, Taiwen Yanhua in North China has been shut down since September 30, 2022, and the start - up time is undetermined; Ningbo Hanwha in East China plans to conduct an overhaul from December 15th to December 28th [87]. Downstream Demand - The two major downstream industries of PVC, profiles and pipes, are facing great pressure. In addition to demand issues, they also face industry competition, so the industry's contribution is difficult to improve. The real - estate sector still provides negative demand feedback, and the domestic demand has not shown obvious improvement. The downstream orders are significantly lower than the average level of the past five years, and both raw material and finished product inventories are at high levels, so the PVC downstream is expected to lack positive drivers [93]. Inventory - The total PVC inventory is still at the highest level in recent years compared to the same period [101]. Export - In October 2025, the PVC export volume was 312,100 tons, with an average export price of 605 US dollars/ton. The cumulative export from January to October was 3.2338 million tons. The single - month export decreased by 9.91% month - on - month, increased by 34.28% year - on - year compared to the same month last year, and the cumulative export increased by 48.88% year - on - year. In October 2025, the PVC import volume was 10,900 tons, with an average import price of 725 US dollars/ton. The cumulative import from January to October was 186,400 tons. The single - month import decreased by 24.14% month - on - month, increased by 20.66% year - on - year compared to the same month last year, and the cumulative import increased by 1.74% year - on - year [119].

Core Insights - The average weekly price of 32% caustic soda is 794 CNY/ton, down 0.75% month-on-month, while the average price of 50% caustic soda remains stable at 1250 CNY/ton [1] - In Shandong province, the market shows mixed performance, with increased inventory leading to price reductions, affecting the overall average price of 32% caustic soda [1] - In Jiangsu, the low-concentration liquid caustic soda market is trending weak, with a weekly average price of 910 CNY/ton, down 2.15% month-on-month, due to lack of demand despite some maintenance in production facilities [1] Inventory Analysis - As of November 12, the inventory of 32% liquid caustic soda in East China is 204,200 tons, a decrease of 5.20% from November 5 [2] - In Shandong, the inventory of 32% liquid caustic soda is 100,800 tons, down 0.79% from November 5, with variations in inventory levels across different factories due to low-price sales and maintenance [2] - The caustic soda industry faces supply-demand pressure, particularly from the main downstream aluminum oxide buyers, leading to weak support for caustic soda prices [2]

1. Report Industry Investment Rating No information about the industry investment rating is provided in the report. 2. Core Views of the Report - **Caustic Soda**: The caustic soda industry still faces certain supply - demand pressures. With fewer maintenance enterprises, the total supply shows an increasing trend. The price of alumina, the main downstream product, continues to weaken, and the industry's profit keeps shrinking with increasing losses. Thus, the support from the main demand side of caustic soda is weak, suppressing the price. In the short term, the caustic soda price lacks support. Although the middle and lower reaches may have phased replenishment needs after consuming their own inventories, the price is still under pressure due to increased supply and weak demand. The non - aluminum market remains sluggish. It is expected that the caustic soda price will run weakly in the short term, and a bearish trend is advised, while tracking the downstream replenishment rhythm [2]. - **PVC**: The contradiction of oversupply has not improved. The pressure on the supply side continues to rise, the demand expectation weakens, and the cost - side support is insufficient. There is no positive macro - level expectation for the time being. Therefore, the price is expected to continue to decline. The main downstream fields such as real estate are still weak. The new orders of profile and pipe product enterprises are limited, mainly for rigid - demand procurement, which is difficult to provide continuous support to the market. There will still be an impact from new production capacity on the supply side from November to December. The demand from November to January of the next year is in the traditional off - season, and the overall real - estate demand will decrease, forming a negative impact. Regarding exports, the anti - dumping tax in India is unclear, and exports are mainly on hold. The supply - demand is still in an oversupply pattern, and it is difficult to be optimistic about the price. Although the absolute price is low, it is difficult to form an upward driving force, and it is expected to continue the downward trend at the bottom [3]. 3. Summary by Relevant Catalogs Caustic Soda - **Price and Market Situation**: The caustic soda price is affected by multiple factors such as macro - environment, alumina demand, and cost. The price has shown fluctuations, with periods of decline due to factors like increased supply and weak downstream demand, and short - term rebounds due to factors such as policy expectations and increased demand from alumina [6]. - **Supply**: The national average weekly weighted operating load rate of sample enterprises is 85.55%, a 0.1 - percentage - point increase from last week. The caustic soda output in terms of 100% strength this week is 82.53 tons, a 0.12% increase from last week. There are many ongoing maintenance of chlor - alkali plants this week, but some enterprises with under - capacity operation have increased their loads, resulting in a slight increase in output [25]. - **Alumina Demand**: From the end of 2024 to 2025, the planned production capacity of alumina is 12.3 million tons (including 2 million tons of replacement), and the estimated annual production capacity growth rate is around 10%. The estimated annual output of alumina in 2025 is over 88 million tons, with a production growth rate of around 6%. The new alumina projects will increase the demand for caustic soda by about 800,000 tons per year, with a relatively concentrated increase of 150,000 tons from April to June [30]. - **Alumina Market**: Although the operating rate of some alumina enterprises in the north has decreased recently, the domestic supply - demand contradiction has not been effectively resolved, and the social inventory of alumina continues to increase. It is expected that the domestic alumina price will continue to run weakly in the short term, with a price range of 2,750 - 2,950 yuan/ton [34]. - **Bauxite**: The bauxite price is stable, the port inventory fluctuates, and the enterprise raw - material inventory has increased significantly [38]. - **Electrolytic Aluminum**: In October, the electrolytic aluminum production remained at a high level, and the in - plant inventory of electrolytic aluminum decreased [44]. - **Non - Aluminum Downstream**: The operating rate of the printing and dyeing and textile industries has increased seasonally, and it is in the peak season. However, the overall non - aluminum downstream has not shown strong driving forces [49]. - **Caustic Soda Export**: In September, the export profit of caustic soda increased, and the export volume rebounded significantly. It is estimated that the export profit will decline in October [54]. PVC - **Price and Market Situation**: The PVC price has been on a downward trend due to the lack of positive supply - demand drivers and a poor commodity atmosphere. The price has been affected by factors such as macro - sentiment, supply - demand changes, and export conditions, with periods of sharp declines and short - term rebounds [61]. - **Profit**: The PVC industry has been in a state of continuous losses, with losses in both the calcium - carbide and ethylene - based production methods [67]. - **Calcium Carbide**: The calcium carbide production has increased month - on - month, but the profit has weakened [72]. - **Supply**: The operating load rate of the domestic PVC powder industry has increased this week. Although there are 4 new enterprises for maintenance or shutdown, the overall maintenance loss has decreased, and the industry operating rate has increased. The overall operating load rate of PVC powder this week is 79.28%, a 2.19 - percentage - point increase from last week [83]. - **Downstream Demand**: The two major downstream industries of PVC, profiles and pipes, face great pressure. The real - estate sector, with the goal of "de - inventorying and stabilizing prices", will continue to have a negative impact on demand. The domestic demand has not improved significantly, and it is expected that the PVC downstream will not have positive drivers [93]. - **Real - Estate Data**: The real - estate industry is still in the bottom - building cycle, with indicators such as housing sales price index, land transaction area, and new - construction area showing weak performance [94]. - **Inventory**: The PVC inventory has remained flat recently, and the total inventory is at the highest level in recent years compared year - on - year [101]. - **External Market**: The external market price of PVC has weakened, and the export situation is affected by factors such as anti - dumping taxes in India [108]. - **Export**: In September 2025, the PVC import volume was 14,400 tons, and the export volume was 346,400 tons. The export volume has increased significantly both month - on - month and year - on - year [119].

Group 1 - The core viewpoint is that the caustic soda market is experiencing a shift towards a stronger price trend due to supply reductions, increased demand, and recovering exports [2][6] - Since July, the market sentiment for caustic soda has been bullish, with futures prices rebounding significantly after hitting a low, with the 2601 contract increasing by over 500 yuan/ton [2] - The supply of caustic soda is expected to decrease due to maintenance schedules for several production facilities, which will support prices [2][6] Group 2 - The demand for caustic soda is anticipated to rise during the "golden September and silver October" period, driven by increased operating rates in industries such as alumina, viscose staple fiber, and lithium hydroxide [4] - As of late August, the domestic alumina operating rate has risen to approximately 85%, an increase of over 15 percentage points from previous lows, with further increases expected [4] - Exports of caustic soda have also shown significant growth, with July exports reaching 30.78 million tons, markedly higher than the same period last year, and cumulative exports from January to July totaling 203.3 million tons, indicating a strong export outlook for the fourth quarter [4][6]

Report Industry Investment Rating - Not provided Core Viewpoints of the Report - The upward trend of caustic soda in the spot market is not over, but the time for a strong rally has not yet arrived. The core lies in the concentrated stockpiling in the alumina and export sectors. Short - term warehouse receipt factors may lead to a phased correction, but there is no need to be overly pessimistic about Zhejiang warehouse receipts [4] Summary by Relevant Catalogs Fundamental Tracking - The futures price of the 11 - contract is 2732, the price of the cheapest deliverable 32% caustic soda in Shandong is 860, the Shandong spot 32% caustic soda converted to the futures price is 2688, and the basis is - 45 [3] - Taking Shandong as the benchmark, the purchase price of 32% caustic soda by major downstream enterprises in Shandong over the weekend was raised by 15 yuan to 815 yuan. Before that, small - scale buyers in the province had already started to raise prices, and caustic soda plants slightly followed suit with a 10 - yuan increase over the weekend. Currently, the short - term inventory of liquid caustic soda in the province remains low, and attention should be focused on changes in the delivery volume to major downstream enterprises [3] Market Condition Analysis - The core driver of the current caustic soda market is the continuous expansion of demand. Non - aluminum demand is expected to improve during the peak season. In Guangxi, there are expectations of 3.6 million tons of alumina production capacity to be put into operation by the end of this year. If the tank - filling and stockpiling go smoothly, the demand is expected to start in October. The caustic soda supply in Guangxi is tight, and most of the caustic soda for tank - filling needs to be purchased from outside. With the flake - liquid caustic soda price spread at a high level this year, the subsequent alumina stockpiling will drive the circulation of domestic 50% caustic soda. If the flake - liquid caustic soda price spread remains strong and the 50 - 32% caustic soda price spread widens, caustic soda will face a continuous positive feedback, and the upward driving force will be stronger than the current situation [4] - The 9.3 military parade affects caustic soda transportation. Recently, the delivery volume of caustic soda to an alumina plant in Shandong has been continuously low, and its purchase price was further raised this weekend. Today, the delivery volume to major downstream enterprises is still lower than the daily consumption and has decreased compared to the previous period [4] - In terms of exports, the support is still strong. The export direction has expanded significantly year - on - year this year, but the stockpiling rhythm will affect the domestic caustic soda price. On the supply side, the weakness of chlorine - consuming downstream industries such as PVC will limit the substantial expansion of the overall industry profit [4] Trend Intensity - The trend intensity of caustic soda is 0, with the value range of trend intensity being an integer within the [- 2, 2] interval. The strength levels are classified as weak, relatively weak, neutral, relatively strong, and strong, where - 2 represents the most bearish and 2 represents the most bullish [5][6]
