Group 1 - The domestic liquid caustic soda market is stable with acceptable transaction volumes, particularly in Shandong where demand remains decent and transportation in Tianjin has resumed, alleviating some shipping pressures for chlor-alkali enterprises [1] - The main prices for 32% liquid caustic soda in Shandong are between 850-915 RMB/ton, while the 50% liquid caustic soda prices range from 1340-1360 RMB/ton [1] Group 2 - As of Thursday, the national average operating rate for major sample enterprises is 86.09%, down 1.25 percentage points from last week due to increased maintenance of chlor-alkali facilities [2] - The inventory of 32% liquid caustic soda in East China decreased by 18.81% to 189,650 tons as of August 20, while Shandong's inventory fell by 19.31% to 67,700 tons, indicating improved purchasing activity from downstream sectors [2] Group 3 - Following the recent military parade, transportation disruptions are expected to ease, allowing liquid caustic soda companies to resume normal supply to downstream markets, with short-term market support from demand [3] - The current low inventory levels in Shandong and the recovery in non-aluminum downstream demand are likely to keep spot prices firm, with increased purchasing activity anticipated as traders prepare for upcoming demand [3]

Report Industry Investment Rating - Not provided in the content Core Viewpoint - The report holds a view of strong current situation but weak future expectations, predicting that the off - season contracts of caustic soda are likely to operate weakly [4] Summary by Relevant Catalogs Supply Side - As of August 29, the weekly production of caustic soda reached 813,200 tons, still at a relatively high level in the past five years but showing a decline. The average operating rate dropped from a peak of 85.1% to 82.4%. The main reasons are the arrival of the autumn regular maintenance peak and temporary shutdowns of some enterprises in Shandong due to traffic control. The current maintenance capacity is 3.13 million tons, and according to the maintenance plan, 2.79 million tons and 1.31 million tons of new maintenance devices are expected in September and October respectively, with the operating rate unlikely to return to the previous high in September. However, some chlor - alkali plants have resumed production after the traffic control in Shandong was lifted [6] - The planned new production capacity this year has decreased from over 4 million tons at the beginning of the year to 2.25 million tons, with some projects postponed to next year due to environmental approval and production profit issues. Currently, Shandong Hydrogen Energy New Energy, Shandong Qingdao Bay, Tianjin Bohua Chemical, and Gansu Yaowang Chemical have all been put into production, and there are still 1.15 million tons of production capacity to be put into operation in the fourth quarter. The achievement rate of production capacity needs to be continuously tracked. Additionally, about 19.25 million tons of caustic soda production capacity is over 20 years old, accounting for 39% of the total capacity. Since the industry is still profitable overall, the impact of the "anti - involution" policy is expected to be limited, and policy changes need to be continuously observed [6] Demand Side - In terms of alumina demand, as of August 29, the latest weekly output of alumina reached 1.847 million tons, at a high level this year. Alumina plants are still profitable, and with the increase in new production in the fourth quarter, the output is expected to rise steadily. Although the alkali - preparation demand before production is lower than that in the first half of the year, the incremental daily alkali consumption demand will still strongly support the caustic soda consumption this year [14] - In terms of non - aluminum demand, the cumulative output of viscose staple fiber in the first seven months of this year was 2.89 million tons, a slight increase of 1.7% compared with the same period last year. The recent seasonal peak season has driven an increase in alkali - preparation demand. The overall starting rate of the printing and dyeing industry is lower than last year, but it has also entered the seasonal peak season recently, with the starting rate rising compared to the previous period. The elasticity and sustainability of peak - season demand need to be continuously observed [14] Market Outlook - The demand side of caustic soda is currently in the early stage of the seasonal peak season. The production has declined due to autumn maintenance, and the inventory has decreased temporarily. The spot price is expected to remain strong in the short term. However, as the peak - season demand fades and the autumn - maintenance production capacity returns, coupled with the fact that the caustic soda inventory this year is still at a high level in recent years, the supply of caustic soda is expected to return to an oversupply situation after October. Therefore, if the seasonal peak season and the overall optimistic sentiment in the commodity market drive the off - season 01 contract to rise significantly to an overvalued level, short positions can be established at high prices after the market fluctuations stabilize or after the warehouse receipts start to be registered. The reference operating range for SH2601 is 2,200 - 2,800 yuan per ton. The changes in peak - season inventory, the registration volume of warehouse receipts, and the progress of alumina production capacity commissioning need to be continuously tracked [3][19]

Report Industry Investment Ratings - Urea: ★★★ (interpreted as a relatively clear upward trend and a relatively appropriate investment opportunity currently) [1] - Methanol: ★★★ [1] - Pure Benzene: ★★★ [1] - Styrene: ☆☆☆ (interpreted as the short - term long/short trend being in a relatively balanced state, with poor operability on the current market, suggesting to wait and see) [1] - Polypropylene: ★★★ [1] - Plastic: ☆☆☆ [1] - PVC: ★★★ [1] - Caustic Soda: ☆☆☆ [1] - PX: ★★★ [1] - PTA: ☆☆☆ [1] - Ethylene Glycol: ★★★ [1] - Short - fiber: ☆☆☆ [1] - Glass: ★★★ [1] - Soda Ash: ★★★ [1] - Bottle Chips: ★★★ [1] - Propylene: ★★★ [1] Core Viewpoints - The chemical futures market shows complex trends, with different products having different supply - demand situations and price trends. Some products are affected by factors such as inventory, production capacity, seasonal demand, and policy expectations [2][3][5]. - For products like methanol and urea, although the current supply is abundant and the market is weak, there are expectations of improvement in the future due to factors such as downstream demand recovery and pre - holiday stocking [6]. - Some products, such as soda ash and glass, are in a situation of high inventory and weak reality, but also have low - valuation characteristics, and their price trends need to be judged based on different market conditions [8]. Summary by Related Catalogs Olefins - Polyolefins - Propylene futures fluctuate narrowly. Enterprises' inventory is low, and offers continue to rise, but high - price transactions are limited [2]. - Polyolefin futures also fluctuate narrowly. Polyethylene supply increases, and demand enters the traditional peak season. Polypropylene supply is relatively loose, and the actual demand recovers slowly [2]. Pure Benzene - Pure benzene returns to above 6000 yuan/ton at night and fluctuates narrowly during the day. Supply increases, demand is weak, and the port inventory accumulates. The market may improve in the third quarter [3]. - Styrene futures get support at the previous low. The cost support is insufficient, and the supply - demand situation is average with high inventory at the terminal [3]. Polyester - PX continues to be weak, and PTA falls with increased positions. The terminal orders increase, but the actual improvement is limited. PX lacks support [5]. - Ethylene glycol fluctuates narrowly at a low level. Supply increases, and the supply - demand situation is weakly stable. There are both supply pressure and demand improvement factors in the medium - term [5]. - Short - fiber supply - demand is stable, and the price fluctuates with the cost. New capacity is limited this year, and the industry expectation is boosted by the peak - season demand [5]. - Bottle chips industry has long - term over - capacity pressure, and the processing margin runs at a low level [5]. Coal Chemical Industry - Methanol imports remain high, and the port inventory accumulates rapidly. Supply increases, but the market expectation is strong due to downstream demand recovery and pre - holiday stocking [6]. - Urea price drops significantly. Supply is sufficient, and the market may oscillate weakly before new positive factors appear [6]. Chlor - alkali - PVC fluctuates narrowly. Supply pressure is high, and demand is weak. The price may oscillate weakly [7]. - Caustic soda price weakens. The inventory situation varies in different regions. The price is relatively firm but may oscillate widely [7]. Soda Ash - Glass - Soda ash oscillates. The supply is high, and the inventory is high. It is recommended to short at high - rebound levels, but be cautious at low - valuation levels [8]. - Glass oscillates. The spot price varies, and the factory inventory decreases. The demand is weak, but the price decline may be limited due to low valuation [8]

1. Report Industry Investment Rating - Not provided 2. Core Viewpoints of the Report - For PVC, the market has a weak supply - demand situation, with long - term supply pressure and low - level downstream demand. Attention should be paid to macro and cost - end impacts, and there is still room for profit compression in the chlor - alkali industry [3]. - For caustic soda, the spot price is stable with a slight increase. Although there are short - term transportation restrictions, the overall order situation in Shandong is acceptable. The cost support remains, and the chlor - alkali profit is at a medium level compared to the same period [4]. 3.

Market Analysis PVC - The PVC futures price stops falling and rebounds. Attention should be paid to the impacts from the macro and cost ends. The supply side has increased maintenance, and the operation rate has decreased month - on - month. However, many maintenance enterprises will resume this week, and the output may increase slightly. In the long - term, the supply - side pressure is still large. The downstream demand remains at a low level, and enterprises maintain just - in - time procurement. The export signing and delivery volume have decreased month - on - month. Affected by India's PVC import policy, the export is expected to be strong before September and weaken in the fourth quarter. The PVC social inventory continues to accumulate, and the absolute inventory value is high. The 09 contract has a large warehouse receipt pressure. The chlor - alkali profit still has room for compression, and the supply - demand situation remains weak [3]. Caustic Soda - The spot price of caustic soda is stable with a slight increase. In September 2025, the delivered price of liquid caustic soda orders of alumina enterprises in Guangxi has increased by 100 yuan/ton compared with last month. The chlor - alkali enterprises have increased maintenance, and the operation rate has decreased but is still at a high level in the same period. Affected by transportation restrictions during the parade, orders from other provinces in Shandong have stopped, and the in - province delivery volume may increase. The receiving price of the main downstream alumina factories in Shandong is mainly stable. Non - aluminum downstream has a fear of high - priced goods. As the peak season is approaching, the overall order backlog in Shandong is acceptable, but the external - province delivery has been suspended in the short - term due to transportation. Attention should be paid to the restocking rhythm of downstream during the "Golden September and Silver October" peak season and the production start - up rhythm of alumina in Guangxi. The electricity price in Shandong has increased slightly in September, the price of liquid chlorine is weak, and the cost support remains. The chlor - alkali profit is at a medium level in the same period [4]. Strategy PVC - Unilateral: Pay attention to macro sentiment. With weak supply - demand, be cautious about shorting at high levels [5]. - Inter - delivery: Reverse arbitrage for V01 - 05 at high levels [5]. - Inter - commodity: None [5]. Caustic Soda - Unilateral: Be cautiously bullish [5]. - Inter - delivery: Positive arbitrage for SH10 - 01 at low levels [5]. - Inter - commodity: None [5].
