Report Summary 1. Investment Rating The report does not provide an industry investment rating. 2. Core Viewpoints - In 2026, the core contradiction in the caustic soda market will revolve around the conflict between "high supply and high inventory" and "negative feedback in the industrial chain due to low profits in the alumina industry." The market is unlikely to experience a trend - based bull market, and the annual price center will be under pressure, likely oscillating within a wide range formed by the "cash - flow cost line" and "downstream periodic restocking." The market will feature an interweaving of "normal pressure" and "pulse rebounds," with the greatest price elasticity and uncertainty coming from unexpected production cuts by chlor - alkali enterprises. Key factors to track include high - frequency inventory data, the pace of alumina production capacity launch, and marginal changes in industrial profits [2][67]. - Domestic terminal demand for caustic soda in China will have limited incremental growth in 2026, while the export market will still show prominent growth. Attention should be paid to short - term supply - demand mismatches in the caustic soda market caused by new alumina production capacity launches and the decline in rigid demand and inventory hoarding due to alumina production cuts. The low - profit situation of caustic soda may lead to unexpected maintenance next year, and major supply - reduction contradictions may come from the passive production cuts of caustic soda caused by PVC. In 2026, the caustic soda delivery rules will be modified, which will change the premium and discount of delivery products and delivery areas, adjust the warehouse receipt trade flow, and intensify the impact of warehouse receipts on the market in the short term [2][67]. 3. Section Summaries 3.1 2025 Caustic Soda Trend Review - The caustic soda market in 2025 experienced significant fluctuations from expectation - driven to fundamentals - dominated. The annual trend can be divided into four main stages: a trend - based upward movement driven by strong expectations from early January to before the Spring Festival; a negative - feedback downward movement due to high profits and weak demand from after the Spring Festival to early May; an interweaving of cost collapse and rebounds from early May to August; and a continuous bottom - seeking under demand negative feedback and high inventory from September onwards [6]. - **First stage (Early January - Before the Spring Festival)**: Driven by the resonance of strong expectations and reality, including alumina industry capacity expansion, pre - production stocking, supply concerns from planned maintenance in South China, and increased overseas export orders, caustic soda prices rose, and inventory decreased. The futures main - contract price reached a maximum of 3358 yuan/ton before the Spring Festival, an increase of about 14.7% from the beginning of the year [7]. - **Second stage (After the Spring Festival - Early May)**: The market logic shifted. High profits led to high operating rates, but demand was weak. Non - aluminum demand recovered slowly, alumina enterprises reduced inventory and pressured prices, and South China's maintenance devices resumed production, leading to a downward trend in the market [8]. - **Third stage (Early May - August)**: Prices rebounded due to short - term restocking demand from new alumina production lines in early May, but cost collapse due to falling coal prices and lower electricity prices led to high profits and a "short - profit" trading logic. A rebound from late June to late August was driven by seasonal maintenance and policy expectations, but it did not change the loose supply - demand situation [9]. - **Fourth stage (September - Present)**: In the fourth quarter, the market continued to seek the bottom. Alumina production cuts due to low profits reduced demand, non - aluminum demand was limited, and exports faced pressure. High operating rates during the off - peak maintenance season led to high inventory, and prices hit new lows, falling below 2200 yuan/ton [10]. 3.2 2026 Caustic Soda Demand Pattern - **External demand drives growth, and domestic demand shows differentiation**: In 2026, China's caustic soda demand pattern will feature external demand driving growth and domestic demand showing differentiation. The export market will remain the core growth driver, with the driving logic shifting to a "structural supply gap" in resource - rich countries like Indonesia. Domestic demand will vary: the alumina industry will have complex demand for caustic soda, the pulp and paper industry will have limited incremental demand, the viscose staple fiber industry will have stable demand, and the printing and dyeing industry will have a stable but un - supportive demand [13]. - **Alumina industry**: In 2026, China's alumina industry will continue to expand production capacity, with about 13.9 million tons of new capacity planned to be put into production in the first half of the year. However, the industry is facing over - supply, and competition will intensify. The demand for caustic soda will show periodic and structural characteristics, with short - term pulse demand from new capacity launches and long - term suppression due to profit concerns. The overall profit situation of the alumina industry will determine the intensity of its demand for caustic soda, and cost - structure differences will lead to demand differentiation [14][22]. - **Pulp and paper industry**: In 2026, the global and Chinese pulp industry will face a complex situation of tightening overseas supply and expanding domestic supply. The demand for caustic soda will be mainly rigid, with limited growth elasticity and high cost sensitivity. Although new domestic chemical pulp capacity will be put into production, it will not significantly increase the overall demand for caustic soda [23][27]. - **Viscose staple fiber industry**: In 2026, the viscose staple fiber industry will have stable and rigid demand for caustic soda. The industry has a concentrated supply pattern, stable demand, and expected profit recovery, which will support high operating rates and continuous demand for caustic soda [30][31]. - **Printing and dyeing industry**: In 2026, the printing and dyeing industry will provide a stable demand base for caustic soda, but its weak profitability will limit its ability to support caustic soda prices. The industry is in a state of low profit or loss, and enterprises will adopt a conservative procurement strategy [35]. - **Export market**: In 2025, China's caustic soda exports increased significantly, with Indonesia becoming the largest export market. In 2026, exports are expected to continue to grow, with an expected year - on - year increase of over 20% and a total volume expected to exceed 4.5 million tons. However, potential risks include the construction of local production capacity in overseas markets, increased international competition, and uncertain trade policies [37][38]. 3.3 2026 Caustic Soda Supply - **Production cuts may exceed expectations**: In 2026, the caustic soda supply side will face the coexistence of "certain production capacity expansion" and "uncertain adjustment effects." The overall supply capacity will continue to grow, but the market will focus on the game between fixed costs and fluctuating marginal profits. Cash - flow cost will form a "hard bottom" for prices, and seasonal and policy - related factors will drive price fluctuations [43]. - **Expected production capacity and output**: In 2026, the caustic soda production capacity is expected to increase by 2.56 million tons, a 5% increase. However, the actual production capacity increase may be about 3% due to the influence of the loss situation of chlorine - consuming downstream industries. The annual output is expected to reach or exceed 45 million tons, a year - on - year increase of nearly 5% [44]. - **Cost and profit**: In 2026, the core game on the supply side will revolve around cost and profit. The cost side is expected to provide stronger support, but profit expansion is difficult due to over - supply and weak downstream profitability. The effectiveness of profit - to - supply transmission needs to be verified, and large - scale and long - term active production cuts of caustic soda may depend on the passive production cuts caused by PVC [47]. - **Impact of loss in chlorine - consuming downstream industries**: The loss of chlorine - consuming downstream products such as PVC will affect the price of liquid chlorine, which in turn affects the comprehensive profit of caustic soda enterprises. When the comprehensive profit is in deficit, enterprises may reduce production. In 2026, the maintenance intensity in spring and summer may exceed that of this year [50]. - **Supply - demand mismatch due to seasonal maintenance and inventory hoarding**: Seasonal maintenance, especially from June to August, can ease the supply pressure. However, when the maintenance season ends, supply will increase. High inventory in 2025 has suppressed demand. When the off - season ends and downstream starts to stock up or new alumina production capacity is launched, a supply - demand mismatch may occur [56][59]. 4. Investment Outlook - **Single - side trading**: In terms of trends, the valuation of caustic soda is under pressure, but it is not advisable to short at the cash - flow cost. Attention should be paid to short - term long - buying opportunities brought by caustic soda supply cuts [3][67]. - **Calendar - spread arbitrage**: There is a positive - spread window period during the peak maintenance season. Attention should be paid to the rebound driven by production cuts and the corresponding downstream active inventory - hoarding space and rhythm [3][68]. - **Key time nodes**: After the Spring Festival, around the start of spring maintenance in March, the situation of summer maintenance from June to August, and before the National Day [3][68].

Report Summary of PVC Industry 1. Industry Investment Rating - No investment rating is provided in the reports [1][2][3] 2. Core Viewpoints - The PVC market's high - production and high - inventory structure is difficult to change in the short term, but supply - side production cuts during the maintenance peak season next year can be expected due to the continuous decline in caustic soda profits and historically low chlor - alkali comprehensive profits [2] - PVC futures prices rebounded starting from last Friday night driven by macro anti - involution sentiment and coking coal rebound. There may still be a small rebound space in the short term, but before the 03 contract, futures contracts face the situation of high开工 and weak demand [1] 3. Summary by Related Catalogs 3.1 Fundamental Data - The 01 contract futures price is 4423, the East China spot price is 4400, the basis is - 23, and the 1 - 5 month spread is - 257 [1] 3.2 Spot Market - The price center of the PVC spot market fluctuates and rises, but the trading atmosphere weakens during the session. The short - term adjustment of the PVC supply - demand fundamentals is limited, the total production reduction by enterprises is small, the market supply remains high, and there is a risk of inventory accumulation. The ex - warehouse cash price of calcium carbide - based type 5 PVC in East China is 4380 - 4500 yuan/ton, and that of ethylene - based PVC is 4450 - 4600 yuan/ton [1] 3.3 Market Situation Analysis - The rebound of PVC futures prices is driven by macro anti - involution sentiment and coking coal rebound. Some devices may cut production due to large losses, but winter is the off - season for chlor - alkali enterprise maintenance, and the scale of new maintenance may be limited. The game of large - scale production cut expectations may occur after the 03 contract. Also, PVC warehouse receipts are still at a high level, and the future pressure on long - position holders to take delivery is large [1] 3.4 Trend Intensity - The trend intensity of PVC is 0, indicating a neutral trend [2]

The news of the planned shutdown of a 450,000 - ton PVC plant in the US boosts the market sentiment, but the spot trading is weak after the price increase. The supply is expected to decrease slightly this week, and the overall supply pattern remains abundant. The downstream start - up rate generally declines, the inventory is slightly reduced but still at a high level. The comprehensive production profit of upstream PVC has decreased, and the export profit has shrunk, but the export orders have strengthened month - on - month [1][3] Caustic Soda - The caustic soda market rebounds with the anti - involution sentiment, and the supply - demand situation has slightly improved. The spot price is mainly stable, and the trading volume has improved at low prices. The inventory in Shandong and Jiangsu has decreased, but it is still at a high level compared to the same period. The supply - side start - up rate is high, and the non - aluminum demand has weakened. Attention should be paid to the price trend of liquid chlorine, the dynamics of caustic soda plants, and the implementation details of the macro - anti - involution policy [2][3] Group 3: Market News and Important Data PVC - Futures Price and Basis: The closing price of the PVC main contract is 4,399 yuan/ton (+84); the East China basis is - 19 yuan/ton (-34); the South China basis is 1 yuan/ton (-64) [1] - Spot Price: The East China calcium - carbide - based PVC is quoted at 4,380 yuan/ton (+50); the South China calcium - carbide - based PVC is quoted at 4,400 yuan/ton (+20) [1] - Upstream Production Profit: The semi - coke price is 780 yuan/ton (+0); the calcium carbide price is 2,930 yuan/ton (+0); the calcium carbide profit is 16 yuan/ton (+0); the gross profit of calcium - carbide - based PVC production is - 1,102 yuan/ton (-83); the gross profit of ethylene - based PVC production is - 520 yuan/ton (-48); the PVC export profit is 3.7 US dollars/ton (-6.9) [1] - Inventory and Start - up: The in - plant PVC inventory is 344,000 tons (+18,000); the social PVC inventory is 517,000 tons (-12,000); the start - up rate of calcium - carbide - based PVC is 79.13% (-2.96%); the start - up rate of ethylene - based PVC is 76.67% (+4.75%); the overall PVC start - up rate is 78.39% (-0.62%) [1] - Downstream Orders: The pre - sales volume of production enterprises is 649,000 tons (-50,000) [1] Caustic Soda - Futures Price and Basis: The closing price of the SH main contract is 2,160 yuan/ton (-3); the basis of 32% liquid caustic soda in Shandong is 90 yuan/ton (+34) [1] - Spot Price: The price of 32% liquid caustic soda in Shandong is 720 yuan/ton (+10); the price of 50% liquid caustic soda in Shandong is 1,140 yuan/ton (-10) [2] - Upstream Production Profit: The single - variety profit of caustic soda in Shandong is 1,229 yuan/ton (+31); the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) is 665.0 yuan/ton (+71.3); the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) is - 546.96 yuan/ton (+51.25); the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) is 280.39 yuan/ton (+20.00) [2] - Inventory and Start - up: The liquid caustic soda factory inventory is 457,100 tons (-47,700); the flake caustic soda factory inventory is 34,500 tons (+800); the start - up rate of caustic soda is 86.20% (+0.20%) [2] - Downstream Start - up: The start - up rate of alumina is 86.11% (-0.09%); the start - up rate of printing and dyeing in East China is 62.74% (-1.72%); the start - up rate of viscose staple fiber is 89.62% (-1.67%) [2]

Core Viewpoint - The caustic soda market is expected to face a structural oversupply in 2026, with supply growth outpacing demand growth, leading to a continued downward pressure on prices [1][5][6] Supply and Demand Dynamics - In 2025, the price of caustic soda fell from a peak of 3332 CNY/ton to 2098 CNY/ton, a decrease of 1234 CNY/ton, primarily due to an imbalance between capacity expansion and demand growth [1] - Domestic caustic soda production capacity increased by 210 million tons in 2025, contributing to a long-term oversupply situation [1] - The aluminum oxide industry, which accounts for 30%-40% of caustic soda demand, is expected to add approximately 11 million tons of capacity in 2025, theoretically increasing caustic soda demand by 1.2 million tons, but actual production is limited by bauxite supply constraints [1][2] - In 2026, the planned new capacity for caustic soda is about 2.19 million tons, with total domestic production expected to reach 43.86 million tons [2] - The overall demand growth for caustic soda in 2026 is projected to slow down compared to 2025 [3] Inventory and Market Pressure - By the end of 2025, caustic soda inventories exceeded 3 million tons, indicating a persistent oversupply [1] - In 2026, inventory pressure is expected to increase significantly, with most companies maintaining inventories above 450,000 tons [2] Cost Factors - The cost support for caustic soda prices is weak, with electricity and raw salt being the main cost components, accounting for 50%-60% and 25% respectively [4] - The price of liquid chlorine, which is produced alongside caustic soda, fluctuated between -650 to 275 CNY/ton in 2025, affecting the pricing dynamics of caustic soda [4] Policy Implications - The "anti-involution" policy proposed by the Ministry of Industry and Information Technology aims to eliminate outdated capacity, potentially impacting caustic soda supply if effectively implemented [5][6] - The actual execution and impact of this policy remain uncertain, and its development will be crucial for the market in 2026 [5][6]
