Report Summary 1. Report Industry Investment Rating - The trend strength of caustic soda is -1, indicating a weak bearish view [4]. 2. Core View of the Report - The caustic soda market is under pressure in the short - term after a valuation repair, and in the long - term, the negative feedback in the industrial chain may occur due to alumina production cuts. The situation can only be changed by supply - side production cuts [3]. 3. Summary by Relevant Catalogs Fundamental Tracking - On November 5, 2025, the 01 - contract futures price of caustic soda was 2336, the cheapest deliverable 32% caustic soda spot price in Shandong was 780, the Shandong spot 32% caustic soda converted to the futures price was 2438, and the basis was 102 [2]. - On November 5, in Shandong, individual enterprises in southwestern and southern Shandong lowered their prices. Due to increased supply in the west, high - price products had poor sales, so they were sold at reduced prices [2]. Market Condition Analysis - The sharp decline in liquid chlorine prices over the weekend increased the cost of caustic soda significantly. However, caustic soda enterprises did not cut production, resulting in insufficient upward drivers [3]. - The pattern of high production and high inventory of caustic soda continues, and the market is continuously shorting the chlor - alkali profit. The impact of alumina's production - start and production - cut expectations on caustic soda basically offsets each other. The winter is a low - maintenance season for chlor - alkali enterprises, and the supply - demand gap caused by stockpiling may be limited. Non - aluminum downstream support is limited, and exports are under pressure, increasing domestic supply pressure [3]. - In the long run, alumina production cuts will lead to negative feedback in the industrial chain, and only supply - side production cuts can change the situation. So, pay attention to the supply changes under the background of liquid chlorine and low profits [3].

Report Industry Investment Rating No relevant information provided. Core Viewpoints - In November, the caustic soda industry still faces certain supply - demand pressures. With fewer maintenance enterprises, the supply is expected to increase. The price is weakly stable, and the overall trend is bearish. For PVC, from November to December, the supply pressure will continue due to new production capacity, and the demand is in the off - season. The price is expected to continue the bottom - oscillating pattern [2][3]. - Futures trading for both caustic soda and PVC should adopt a bearish approach, and options trading should be on the sidelines [4][5]. Summary by Related Catalogs Caustic Soda - **Price and Market Situation**: The price of caustic soda futures has fluctuated due to various factors such as macro - environment, supply - demand changes, and cost shifts. The spot price has also been affected by factors like downstream demand and inventory. In November, the price is expected to be weakly stable [2][8]. - **Supply**: In October, the industry's operation was at a high - level with fluctuations, and the inventory of caustic soda plants first decreased and then increased. The national average weekly weighted operating load rate was 85.55%, a 0.1 - percentage - point increase from the previous week. The caustic soda production in terms of 100% purity was 82.53 tons, a 0.12% increase from the previous week [21][27]. - **Demand**: The main downstream, alumina, has a weakening demand for caustic soda. From the end of 2024 to 2025, the planned new alumina production capacity is 1230 tons, which is expected to increase the demand for caustic soda by about 80 tons per year [32]. - **Export**: In September, the export profit of caustic soda increased, and the export volume rebounded significantly. In October, the estimated export profit declined [56]. Polyvinyl Chloride (PVC) - **Price and Market Situation**: In October, the PVC spot price decline accelerated. The core contradiction is that the supply - demand situation has not been substantially improved. The futures price has also been affected by factors such as supply - demand, macro - environment, and cost [63][64]. - **Supply**: In October, there were 20 PVC maintenance enterprises, 3 fewer than in September. The utilization rate of calcium - carbide - based PVC production capacity was 78.10%, a 0.49 - percentage - point decrease from September. The utilization rate of ethylene - based PVC production capacity was 81.48%, a 2.46 - percentage - point increase from September [79][85]. - **Demand**: The two major downstream industries of PVC, profiles and pipes, face great pressure. The real - estate sector continues to have a negative impact on demand. The downstream orders are significantly lower than the average of the past five years, and the raw material and finished - product inventories are at high levels [94]. - **Inventory**: The PVC inventory has been continuously increasing, and the total inventory is at the highest level in recent years compared year - on - year [102]. - **Export**: In September 2025, the PVC import volume was 1.44 tons, with a single - month import increase of 16.08% month - on - month and 7.73% year - on - year.

Report Industry Investment Rating - The investment view is "oscillating", indicating that the short - term market has no obvious driving force, and the price is expected to mainly fluctuate [3]. Core View of the Report - The spot price of caustic soda is stable with a slight decline, and the futures market is oscillating weakly. The supply has increased due to reduced maintenance and higher production. The demand is mixed, with alumina开工 declining and non - aluminum demand weak in some aspects, while other downstream industries show some improvements. Inventory has accumulated, and profits have decreased. The overall market is expected to be in a state of oscillation [3][6]. Summary by Relevant Catalogs Part One: Main Views and Strategy Overview - **Supply**: It is neutral. This week, maintenance decreased, and production increased. The weekly domestic caustic soda production rose by 24,000 tons to 830,000 tons. The average capacity utilization rate of sample enterprises with 200,000 tons or more of caustic soda was 84.3%, a week - on - week increase of 3.5%. Most regions saw an increase in load, except for Central China [3]. - **Demand**: It is neutral. Alumina开工 decreased, and non - aluminum demand was weak. The capacity utilization rate of the viscose staple fiber industry was 89.64%, a week - on - week increase of 1.03%. The comprehensive startup rate in the Jiangsu and Zhejiang regions was 68.32%, a week - on - week increase of 1.01%. The monthly开工 rate of lithium hydroxide in China in June 2025 was about 49.27%, and the overall output was basically flat after offsetting increases and decreases [3]. - **Inventory**: It is bearish. Recently, the shipment pressure increased, and caustic soda inventory accumulated. The factory inventory of fixed liquid caustic soda sample enterprises with 200,000 tons or more was 442,600 tons (wet tons), a week - on - week increase of 6.84% and a year - on - year increase of 52.42%. The national liquid caustic soda sample enterprise storage capacity ratio was 25.75%, a week - on - week increase of 1.56% [3]. - **Basis**: It is neutral. The current basis of the main contract is around 95, and the futures price is at a discount [3]. - **Profit**: It is bearish. The weekly average gross profit of chlor - alkali enterprises in Shandong was 292 yuan/ton, a week - on - week decrease of 17%. Liquid chlorine prices rose, and caustic soda prices fell, leading to a decline in overall chlor - alkali profits [3]. - **Valuation**: It is bearish. The spot price is neutral, and the absolute futures price is low. The near - month contract is at a discount [3]. - **Macro Policy**: It is neutral. The anti - involution sentiment in the energy and chemical sector has subsided, and the futures market trades based on fundamentals [3]. - **Investment View**: The short - term futures market has no obvious driving force, and it is expected to mainly oscillate [3]. - **Trading Strategy**: There are no unilateral or arbitrage strategies at present. Attention should be paid to changes in liquid chlorine prices, rotation storage policies, and the global economic recession [3]. Part Two: Futures and Spot Market Review - The futures market oscillated within a range. This week, the spot price in Shandong was stable with a slight increase, while the futures price hit a new low. The liquid chlorine subsidy was less, and the liquid chlorine price rose to 350 yuan/ton. Chlor - alkali profits remained high, and factory开工 loads remained high. Demand reached the turning point between peak and off - peak seasons. In the future, the new maintenance intensity of alumina will increase, and the supply and demand of caustic soda will turn to be loose. The spot price is expected to be stable with a slight decline. Future attention should be paid to changes in liquid chlorine and the alumina production start - up rhythm [6]. Part Three: Caustic Soda Supply and Demand Fundamental Data - **Electricity Price**: Coal supply was tight, and electricity prices rose [29]. - **Device Loss and Production**: In the main production areas, maintenance in North China decreased, and production increased [34]. - **Chlor - Alkali Profit**: Chlor - alkali comprehensive profits decreased [42]. - **Downstream Price**: Alumina prices declined, and non - aluminum prices were weak [45]. - **Alumina**: Alumina开工 recovered, and inventory accumulated. Due to the end of maintenance and the commissioning of new devices, the alumina开工 rate in Henan increased significantly. Alumina supply - demand balance was restored, inventory accumulated, port bauxite inventory decreased, and alumina profits were good and remained stable year - on - year [57][68]. - **Non - Aluminum Demand**: Non - aluminum开工 remained stable but was lower than the same period last year. Non - aluminum demand entered the seasonal off - peak season, and开工 began to decline [69]. - **Liquid Chlorine Downstream**: The开工 rate rebounded [78]. - **Subsequent Maintenance Information**: Multiple enterprises in different regions have planned or are expected to carry out maintenance in October and November [82].

1. Report Industry Investment Ratings No information provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: In November, with few PX unit overhauls in Asia and China, but concentrated PTA unit overhauls, PX supply - demand is expected to be weak. PX absolute prices are expected to gradually face pressure. The strategy is to follow crude oil for unilateral trading and go short on rallies, and try to shrink the PX - SC spread [1]. - PTA: In November, there are still many PTA unit overhaul plans. With better - than - expected terminal and polyester demand in October and low polyester inventory, PTA supply - demand is expected to be slightly loose with a small inventory accumulation expectation. PTA will continue to oscillate at a low level. The strategy is to follow crude oil for unilateral trading and go short on rallies, and treat TA1 - 5 as a rolling reverse spread [1]. - Ethylene Glycol (MEG): In November, domestic supply is high, overseas shipments are concentrated, and inventory accumulation is expected to be high, putting pressure on the price. The strategy is to sell out - of - the - money call options on rallies and do a reverse spread on EG1 - 5 on rallies [1]. - Short Fiber: In November, supply is expected to remain high, demand may weaken seasonally, and cost support is limited. Short - fiber prices will gradually face pressure. The strategy is similar to PTA for PF12, and try to shrink the PF processing margin when it is above 1000 [1]. - Bottle Chips: In November, supply changes little, demand is in the off - season, and the supply - demand pattern remains loose. Bottle - chip prices will follow the cost side, and the processing margin will fluctuate with raw material costs. The strategy is similar to PTA for PR, and the main - contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [1]. Chlor - Alkali Industry - Caustic Soda: In November, supply is expected to increase, demand support is weak, and prices are expected to be weakly stable. The overall trend is bearish, and it is necessary to track downstream restocking rhythm [2]. - PVC: In October, PVC prices continued to decline. In November - December, supply pressure will continue due to new capacity and high - season operation, and demand is in the off - season. Prices are expected to continue to oscillate at the bottom [2]. Methanol Industry The current market is trading the "weak reality" logic centered on high port inventory. Before the Iranian gas restriction, the weak reality will continue to be priced in. The 01 - contract inventory problem cannot be solved [3][4][5]. Pure Benzene - Styrene Industry - Pure Benzene: In November, supply is expected to be loose, demand support is limited, and although the East China port inventory decreased in October, it may increase later. Pure - benzene prices are expected to have weak driving force, but attention should be paid to unit changes [8]. - Styrene: In November, supply may slightly decrease, demand is expected to change little, and the supply - demand may be in a tight - balance state. However, high port inventory will limit price increases. The strategy is to be bearish on EB12 price rebounds [8]. Polyolefin Industry PP supply recovery has slowed down due to unplanned overhauls, while PE supply is expected to increase. Demand has recovered, but the agricultural film peak is approaching. Overall, supply will increase and demand will decrease, and there is inventory pressure on the 01 - contract. The 05 - contract may have long - term low - buying opportunities, and the monthly spread is suitable for reverse spreads [10]. 3.

1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The current spot market for caustic soda is weaker than expected, with non - aluminum sectors showing no obvious restocking behavior and speculative demand remaining subdued. As maintenance work concludes, supply pressure is rising, and the strong price of liquid chlorine is weakening cost support [1]. - The high - profit and high - production pattern restricts the price increase of caustic soda. There are limited overall contradictions, but the near - term demand and restocking rhythm are falling short of expectations, leading to a judgment of weak and volatile prices. It is recommended to adopt range - bound trading strategies within the range of [2200, 2400] [5]. 3. Summary by Relevant Catalogs 3.1 Chapter 1: Core Contradictions and Strategy Recommendations 3.1.1 Core Contradictions - **Near - term trading logic**: The overall spot market is weak, with non - aluminum restocking falling short of expectations. Alumina is under pressure, with local supply adjustments and a slight decline in operating rates, which may affect the demand outlook for caustic soda. The chlor - alkali industry maintains medium - to - high profits, and the recent strength of liquid chlorine weakens cost support. Production is increasing, and supply pressure persists [1]. - **Long - term trading expectations**: High profits limit price increases. In the medium - to - long term, there is continued pressure from new production capacity. The realization degree and timing of downstream alumina production capacity may vary, affecting the phased restocking rhythm [1]. 3.1.2 Trading - Type Strategy Recommendations - **Market positioning**: The high - profit and high - production pattern restricts the price space of caustic soda. Overall contradictions are limited, but near - term demand and restocking rhythm are below expectations. It is recommended to trade within the range of [2200, 2400] [5]. - **Basis, calendar spread, and hedging arbitrage strategy recommendations**: Current short positions on a single - side basis are advised to be closed, or wait for signs of the spot market hitting bottom [6]. 3.1.3 Industrial Customer Operation Recommendations - **Price range forecast**: The predicted monthly price range for caustic soda is 2200 - 2400, with a current 20 - day rolling volatility of 22.75% and a historical percentile of 43.8% over three years [7]. - **Risk management strategy recommendations**: For inventory management, when product inventory is high and there are concerns about price drops, enterprises can short caustic soda futures to lock in profits and sell call options to collect premiums. For procurement management, when the regular inventory for procurement is low, enterprises can buy caustic soda futures to lock in procurement costs and sell put options to collect premiums [7]. 3.1.4 Basic Data Overview - **Factory - gate prices**: The factory - gate prices of 32% caustic soda in various regions on October 31, 2025, mostly remained unchanged compared to the previous day, except for a 1.5% decrease in Shaanxi Beiyuan. The prices of 50% caustic soda and flake caustic soda also showed little change, with a 1.5% decrease in Shandong flake caustic soda [8][9]. - **Price differentials**: The price differentials between different grades and regions of caustic soda were mostly stable on October 31, 2025, with a 10 - yuan decrease in the price differential of 50% caustic soda between Guangdong and Shandong [9]. - **Futures prices and spreads**: On October 31, 2025, the caustic soda 05 contract increased by 0.12%, the 09 contract decreased by 0.16%, and the 01 contract decreased by 0.3%. The basis and spreads also showed corresponding changes [10]. 3.2 Chapter 2: This Week's Important Information and Next Week's Focus Events 3.2.1 This Week's Important Information - **Positive information**: There are still expectations for downstream aluminum plants to stock up on caustic soda from November to December, which may boost the spot market [10]. - **Negative information**: Caustic soda production continues to recover, increasing supply pressure. Non - aluminum sectors have not shown concentrated restocking. The high price of liquid chlorine weakens cost support [13]. 3.2.2 Next Week's Important Events to Watch - Whether liquid chlorine prices will continue to rise, which would further weaken the cost support for caustic soda. - Observe the mid - and downstream demand, especially whether non - aluminum sectors will show restocking signs. - Monitor whether inventory accumulation continues [13]. 3.3 Chapter 3: Market Interpretation 3.3.1 Price, Volume, and Capital Interpretation - The main 2601 contract of caustic soda showed low - level fluctuations this week, with the absolute price reaching a relatively low level for the year. This is mainly related to market sentiment and weak market conditions, as non - aluminum downstream restocking in the short - term fell short of expectations [14]. - **Basis and spread structure**: The spot market remained stable, with the 32% caustic soda from Shandong Jinling converted to the futures price at 2406 yuan/ton, with a premium of 95 - 100 yuan over the 01 contract. The spot market was weak, and the 12 - 01 spread was positive [16]. 3.4 Chapter 4: Valuation and Profit Analysis 3.4.1 Upstream and Downstream Profit Tracking in the Industry Chain - Profit valuation is moderately high. This week, the price of industrial salt remained stable, while the price of liquid chlorine was strong, resulting in high chlor - alkali profits. Currently, the price of liquid chlorine in Shandong is 250 yuan/ton, and in Jiangsu it is 200 yuan/ton (up 100 yuan). The current profit of caustic soda in Shandong is over 400 yuan/ton (including liquid chlorine) [21]. 3.4.2 Import and Export Profit Tracking - In terms of exports, the CFR price in Southeast Asia increased by 5 US dollars week - on - week to around 460 US dollars, remaining generally stable. There is an expected substitution effect on overseas caustic soda demand, and the sustainability of exports needs to be observed [28]. 3.5 Chapter 5: Supply, Demand, and Inventory 3.5.1 Spot Data - **Caustic soda prices**: The report provides historical price trends of 32% caustic soda, 50% caustic soda, and flake caustic soda in different regions, as well as price differentials between regions and grades, and spot - to - futures conversion prices [30][35][40]. - **External market prices**: It shows the historical price trends of caustic soda in international markets such as Northeast Asia, Southeast Asia, the United States, and Western Europe [84]. 3.5.2 Supply Side - **Production losses**: It presents the seasonal trends of weekly and monthly production losses of caustic soda [93]. - **Liquid caustic soda production and operating rates**: The weekly and monthly production and operating rates of liquid caustic soda in different regions are provided, showing an overall upward trend in production and relatively stable operating rates [95][96]. - **Flake caustic soda production and operating rates**: The weekly production and operating rates of flake caustic soda in different regions are presented, with production and operating rates also showing certain trends [105]. 3.5.3 Demand Side - **Downstream product data**: It includes the spot price, cost, and profit of alumina, as well as the operating rates of downstream products such as propylene oxide, epichlorohydrin, and viscose staple fiber [112][113]. - **Export structure**: The export structure of caustic soda by continent is shown [119]. 3.5.4 Inventory - **Liquid caustic soda inventory**: The weekly factory inventories of liquid caustic soda in different regions and the overall inventory trends are provided [121][124]. - **Flake caustic soda inventory**: The weekly factory inventories and total industry inventories of flake caustic soda in different regions are presented [140][142].
