1. Report Industry Investment Rating No information provided in the text. 2. Report's Core View Polyolefin - In September, the polyolefin market shows a phased characteristic of "decreased supply and increased demand", with inventory being reduced and overall market pressure under control. It is recommended to continue holding the expanding position of the LP01 contract [2]. Caustic Soda - The caustic soda market is strong in the short - term. After the parade, there may be an increase in orders from other provinces, and some caustic soda plants may raise prices. It is necessary to pay attention to the downstream purchasing rhythm and device fluctuations [4]. PVC - The PVC market continues to be in a situation of oversupply. Although it is the traditional demand peak season in September, demand remains sluggish. It is expected to continue weak and volatile [4]. Crude Oil - Overnight oil prices rose. The supply side supports buying, while the demand side is under pressure. It is recommended to pay attention to the subsequent OPEC+ meetings. In the short - term, wait and see, use a positive arbitrage strategy, and look for opportunities to expand options after the volatility increases [7]. Methanol - The methanol supply is expected to increase, while the traditional downstream demand is weak. It is necessary to focus on the restart of MTO devices at ports and the inventory digestion rhythm. The 01 contract can consider the possibility of a decline in imports due to gas restrictions in Iran [17]. Urea - The urea futures price rebounded slightly, driven by supply - side maintenance and Indian tender news. However, weak demand limits the upside space [21]. PX - PX supply is expected to increase, and the supply - demand is in a tight balance in September. PX11 can focus on the area around 6800 [25]. PTA - PTA supply - demand is expected to improve, and the absolute price is supported in the short - term. [26] Ethylene Glycol - In September, domestic ethylene glycol supply is high, imports are revised down, and port inventories are low. Consider going long EG2601 or selling put options EG2601 - P - 4300 [26]. Short - fiber - In September, short - fiber supply - demand is expected to improve, but the inventory reduction is limited. The price fluctuates mainly with raw materials [26]. Bottle Chip - In September, bottle chip manufacturers maintain a 20% production cut. Demand declines slightly, and the upside space is limited [26]. Pure Benzene - Pure benzene supply is expected to remain high, demand support is weak, and the absolute price is under short - term pressure. However, the strong oil price restricts the downward space. For BZ2603, focus on the area around 5800 - 6000 [34]. Styrene - Short - term styrene supply is high, and the driver is weak. However, there is an expectation of supply - demand improvement in the future, and the downward space is limited. Consider going long lightly below 7000 and focus on the support around 6900, and then mainly short on rebounds [34]. 3.

Report Summary 1. Investment Rating No investment rating information is provided in the report. 2. Core View The chlor-alkali - PVC industry is currently in a "subsidizing chlorine with caustic soda" situation. The downstream of caustic soda, such as the alumina industry, is more prosperous than the downstream of PVC, about 60% of whose terminal demand is related to real estate. The high - level operation rate of the alumina industry and new capacity additions in 2025 support the demand for caustic soda. As long as the profit of caustic soda can cover the loss of PVC, chlor - alkali integrated plants may maintain a high operation rate. The situation of strong caustic soda and weak PVC may continue until the real - estate market improves significantly or the comprehensive profit of upstream chlor - alkali integrated plants incurs continuous losses, forcing upstream production cuts [2][13][37]. 3. Summary by Directory 3.1 Upstream and Downstream Industry Chain of Caustic Soda and PVC - **Caustic Soda**: Chemical name is sodium hydroxide (NaOH), with solid and liquid forms. The main production process is the ion - exchange membrane electrolysis method. Its cost mainly comes from electricity (60%) and raw salt (20%). It is mainly used in alumina production (over 30% consumption), and also widely used in other industries. Co - produced with it are liquid chlorine and hydrogen [4][5]. - **PVC**: A polymer of vinyl chloride monomer, mainly produced by the calcium carbide method (about 80% of production) and the ethylene method (about 20% of production) in China. Its downstream consumption is mainly in the construction industry (over 60% consumption) [5][6]. - **Chlor - Alkali Balance**: In the chlor - alkali production process, 1 ton of caustic soda is accompanied by 0.886 tons of liquid chlorine. The downstream demands of the two products are different. When caustic soda demand is good and its price rises, liquid chlorine production increases, and may lead to oversupply and price decline, resulting in the "subsidizing chlorine with caustic soda" situation [8]. 3.2 Current Supply and Demand Fundamentals of Caustic Soda and PVC - **Profit Situation**: About 90.9% of PVC production capacity in China is equipped with caustic soda production devices. The industry is in a "subsidizing chlorine with caustic soda" pattern. The single - product profit of caustic soda in Shandong in August 2025 was 1500 - 1700 yuan/ton, while PVC had a loss of (- 1000) - (- 250) yuan/ton. The comprehensive profit of chlor - alkali in Shandong was 400 - 700 yuan/ton, and in the northwest region was 1300 - 1600 yuan/ton [10][13][14]. - **Inventory Situation**: The inventory of 32% liquid caustic soda in East China sample enterprises decreased by 6.37% from August 20 to August 27. The PVC inventory in sample warehouses in East and South China increased, while the PVC inventory in production enterprise factories decreased [16][18]. - **Downstream Demand Situation**: The planned alumina production capacity to be put into operation from the end of 2024 to 2025 is 1230 tons, with an estimated annual production capacity growth rate of about 10%. The monthly production of viscose staple fiber has been increasing since June - August 2025, and its inventory is low. In August 2025, the PVC powder production increased by 4.62% compared with July, and the annual cumulative production from January - August increased by 2.67% compared with the same period in 2024. The PVC supply is expected to remain high in September, and the domestic demand is expected to improve slightly but limitedly [20][26][27]. 3.3 Market Outlook The situation of strong caustic soda and weak PVC may continue until the real - estate market improves significantly or the comprehensive profit of upstream chlor - alkali integrated plants incurs continuous losses, forcing upstream production cuts. Otherwise, the weak situation of PVC is difficult to change in the short term [37].

1. Report Industry Investment Rating - Not provided in the content 2. Core Viewpoints of the Report - Wait for short - selling opportunities for caustic soda, but the upside space may also be large. Caustic soda is currently supported by peak - season expectations and procurement, with spot prices showing a firm trend. However, the 01 contract is in the off - season, and spot prices may fall again later. [3] - The caustic soda market in August was mainly driven by demand, showing a pattern of rising first and then falling. Looking forward, caustic soda is about to enter the seasonal peak season, and the growth of non - aluminum demand may further boost the near - term market. It is not recommended to chase the rise, and short - selling opportunities can be sought after the full release of price elasticity driven by this round of demand. [5] 3. Summary by Relevant Catalogs 3.1行情回顾 (Market Review) - In August, the caustic soda futures showed a trend of rising first and then falling. The early - stage rise was mainly driven by downstream demand, with the main contract SH2601 rising from a minimum of 2,521 yuan/ton to a high of 2,764 yuan/ton, an increase of 10.43%. The late - stage decline was due to the approaching delivery of the near - month 09 contract, with a large number of registered warrants in the Zhejiang region, suppressing the near - month contract. [13] - Overall, the caustic soda spot market was strong due to downstream demand and peak - season expectations. After the digestion of warrants for near - month delivery, the caustic soda futures are expected to continue to be strong. Attention should be paid to the sustainability of this price increase cycle. [14] 3.2现货价格 (Spot Prices) - Data on the spot prices of 32% caustic soda, 50% caustic soda, and 99% flake caustic soda in different regions such as Shandong, Jiangsu, Inner Mongolia, and Henan on August 28, 2025, were presented.

The cumulative imports from January to July were 232,310 tons, a year - on - year decrease of 96.21%. Exports were 30,78 tons, a year - on - year increase of 59.61% and a month - on - month increase of 5.79%. The cumulative exports from January to July were 2.0333 million tons, a year - on - year increase of 53.79%. [58] - Information on the imports and exports of solid caustic soda in July 2025 was also provided, with imports of 643.49 tons (a month - on - month decrease of 25.42% and a year - on - year decrease of 41.59%) and exports of 63,849.67 tons (a month - on - month increase of 7.30% and a year - on - year increase of 99.89%). [66] 3.6需求端 (Demand Side) - In August, the domestic alumina market price stopped rising and started to fall. The profit of alumina was acceptable, with high production willingness and high operating capacity. The demand for alumina in the north decreased slightly, while that in the south increased significantly. The overall spot trading volume decreased, and the price was stable with a slight decline. As of August 26, the built - in capacity of alumina in China was 11.8 million tons, the operating capacity was 9.52 million tons, and the operating rate was 82.93%. [71] - In August, the domestic viscose staple fiber market price recovered. The monthly average price was 12,902 yuan/ton, a month - on - month increase of 100 yuan/ton (0.80%). The cost side continued to decline, the inventory level decreased, and the demand support was strong. [71] 3.7库存 (Inventory) - In August, the national liquid caustic soda factory inventory first increased and then decreased, with limited overall changes, while the flake caustic soda inventory increased. The inventory in Shandong, the benchmark region, had limited pressure, and enterprises had a strong willingness to raise prices. As of August 29, 2025, the domestic liquid caustic soda factory inventory was 262,100 tons, a slight decrease compared to August 1.
