Core Viewpoint - The polyester industry is experiencing an unusual pricing cycle characterized by "off-season price increases and peak-season promotions," deviating from the traditional pattern of "off-season promotions and peak-season price increases" [1][4]. Group 1: Pricing Dynamics - In September 2025, polyester factories saw an average sales rate of 186.4% for polyester filament, with some factories reaching as high as 400% due to strong promotional policies [1]. - The price of PTA increased by 18% in a single month during the off-season due to maintenance shutdowns of several domestic PTA facilities, leading to a rise in polyester product prices [3]. - The market is witnessing a structural mismatch in capacity, where companies over-expand during peak seasons, resulting in excess supply, while reducing production during off-seasons due to inventory concerns, creating conditions for price increases [3][5]. Group 2: Market Expectations and Demand - The disconnect between market expectations and actual demand is a core reason for the current pricing anomaly, with external factors like geopolitical tensions and rising oil prices pushing up raw material costs [4][5]. - The cautious purchasing behavior of downstream weaving enterprises has led to a situation where they prefer "just-in-time" procurement rather than stockpiling, increasing uncertainty in production plans [7][9]. - The phenomenon of "off-season price increases" reflects a strong demand that exceeds expectations, driven by factors such as "export grabbing" [3][4]. Group 3: Industry Challenges - The frequent price fluctuations disrupt normal production schedules and hinder the establishment of a stable pricing system, leading to a vicious cycle of "wait-and-see—demand—shrinkage—promotion—more waiting" [7][9]. - The profit distribution within the polyester industry is severely imbalanced, with upstream raw material producers benefiting from price increases while polyester manufacturers struggle with low margins [9][10]. - Small and medium-sized enterprises face significant challenges due to their limited ability to withstand price wars and cash flow pressures, exacerbated by the current pricing dynamics [10][11]. Group 4: Solutions and Future Outlook - Industry experts suggest that breaking the current pricing cycle requires rebuilding trust between upstream and downstream players, moving from a "zero-sum game" mentality to a collaborative ecosystem [11][12]. - Addressing structural overcapacity on the supply side and actively exploring new market demands on the demand side are crucial for stabilizing the industry [12][13]. - The focus should shift from price competition to value competition, emphasizing technological innovation and optimizing capacity structures to escape reliance on promotions [12][13].

Report Industry Investment Rating No relevant content provided. Core Views Chlor - Alkali Industry - The caustic soda futures market is stabilizing, with overall commodity sentiment positive. Supply may decline due to planned maintenance, and demand from the alumina industry is weakening, while non - alumina demand is improving but with limited price support. Spot prices may stabilize, and the downside of futures prices is limited [27]. - The PVC futures market is rebounding, driven by macro - sentiment. Supply is expected to decrease due to more maintenance this week, and demand from downstream products is slightly increasing. The cost side is providing bottom support, and it is expected to stop falling in the peak season from September to October [27].

The inventory pattern is relatively healthy, and the overall valuation is neutral. The market is swinging between high - inventory reality and overseas gas - restriction expectations, and the inventory inflection point should be monitored [42]. LLDPE - PP Industry - PP's PDH and propylene - purchasing profits are suppressed, with more unplanned maintenance and falling inventory, but the basis is still weak. PE's maintenance is at a relatively high level, with short - term low supply pressure, rising basis, and inventory reduction. Demand for new orders is poor, and the market is in a state of "decreasing supply and increasing demand" [45]. Crude Oil Industry - Overnight oil prices rose due to geopolitical conflicts, which increased concerns about supply disruptions of Russian refined oil and crude oil. The market's focus has shifted to immediate supply risks, and the oil price is likely to run along the upper edge of the shock range in the short term.

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the reports. 2. Core Views of the Reports Polyolefin Industry - The market is in a state of "supply reduction and demand increase" with no obvious core contradictions. For PP, due to strong propylene and propane prices, PDH and external propylene procurement profits are suppressed, leading to more unplanned maintenance and inventory decline, but the basis is still weak due to new device commissioning. For PE, current maintenance remains at a relatively high level, resulting in low short - term supply pressure, rising basis, and inventory depletion. However, attention should be paid to the supply rhythm as maintenance volume may gradually decrease from mid - September. Current new orders for demand are poor, and attention should be paid to downstream replenishment before the Double Festival [2]. Crude Oil Industry - Overnight oil prices rose. The main trading logic is the market's concern about the interruption of refined oil and crude oil supply from Russia due to the escalation of geopolitical conflicts. The market's expectation of tight diesel supply has heated up, which may drive the crack spread to strengthen. At the macro level, the market expects the Fed to cut interest rates soon, and the weakening of the US dollar also provides additional upward momentum for oil prices. The current market trading focus has shifted from the easing expectation to the spot supply risk dominated by geopolitical factors, and the futures price is likely to run along the upper edge of the shock range in the short term. It is recommended to mainly wait and see on the single - side, with the upper pressure of WTI at [65, 66], Brent at [68, 69], and SC at [500, 510]. Wait for opportunities to expand the spread on the option side [4]. Chlor - Alkali Industry - For caustic soda, the futures price has stabilized and rebounded. From the supply side, there are maintenance plans in the northwest and northeast this week, and the operating rate is expected to decline. From the demand side, the main alumina enterprises have good receiving, but the alumina itself is in an oversupply pattern, and the price has shown a downward trend recently, and most alumina plants have sufficient raw material inventory days. The non - aluminum end demand has improved in the peak season, but the support for the caustic soda price is limited. Overall, the Shandong region has significantly accumulated inventory, but the main buyers have good willingness to receive, and the spot price may tend to be stable. Therefore, the downward space of the futures price may be limited. For PVC, the futures price has shown signs of stabilizing and stopping falling. On the supply side, there are many maintenance enterprises this week, and the output is expected to decline. On the demand side, the operating rate of downstream products has increased slightly, and some enterprises are preparing inventory for the National Day. The overall supply - demand pattern shows a marginal improvement trend. The supply tension of raw material calcium carbide has gradually eased, and the price has a narrow downward trend, while the ethylene price is weakly stable, and the cost side maintains bottom support [9]. Polyester Industry Chain - For p - xylene (PX), as domestic and foreign PX maintenance devices resume operation and short - process benefits are good, PX supply gradually increases to a relatively high level. Although the "Golden Nine and Silver Ten" expectation still exists, the polyester and terminal loads are slowly recovering, providing some short - term support for demand. However, the expectation for new orders and load peaks in the future is limited. The PX supply - demand is expected to be relatively loose in September, but the medium - term supply - demand is expected to be tight, and the price has support at the low level. This week, the PX price has shifted to November and December. Under the scenario of downstream demand transfer in the fourth quarter, the positive support for PX is limited. It is expected that PX will fluctuate strongly with the oil price in the short term, but the rebound space is limited. For PTA, the PTA supply - demand is expected to be tight in September as device maintenance is still concentrated. However, due to the good liquidity in the spot market and the sales of some mainstream suppliers, the overall spot basis is weak. The demand side has some support, but the basis and processing fee repair drive are limited under the weak medium - term supply - demand expectation, and the absolute price follows the raw material fluctuation. For ethylene glycol, the supply pattern is strong in the near term and weak in the long term. The import expectation is not high in September, and as it enters the peak demand season, the polyester load increases, and the rigid demand support improves, resulting in low port inventory and a strong basis. However, the supply - demand is expected to be weak in the fourth quarter due to new device commissioning and device restart, and ethylene glycol will enter the inventory accumulation channel, with the price under pressure. For short - fiber, the short - term supply - demand pattern is weak. The supply continues to increase, and although there is still the "Golden Nine and Silver Ten" expectation, new order follow - up is insufficient, and the peak season this year is not expected to be very prosperous. Currently, short - fiber factory inventory is low, and it has relatively strong support compared to raw materials. Overall, it mainly follows the raw material fluctuation. For bottle - grade polyester chips, in September, device restart and shutdown coexist, and supply increases slightly. Considering the decline in soft drink and catering demand as the weather turns cooler, demand may decline, and inventory is expected to increase slowly. The price mainly follows the cost side, and the processing fee has limited upward space [13]. Methanol Industry - In terms of supply and demand, the inland supply is at a high level year - on - year. Although unplanned maintenance has increased recently, some devices are expected to resume production in mid - September. With continuous external procurement by some olefin plants in the inland and unexpected maintenance, the inventory pattern is relatively healthy, which supports the price. The demand side is weak due to the off - season of traditional downstream industries. Some previously shut - down MTO plants at the port restarted last week, slightly relieving the port inventory pressure. In terms of valuation, the upstream profit is neutral, the MTO profit is marginally weakening, and the traditional downstream profit is still weak, with the overall valuation being neutral. The port is continuously accumulating a large amount of inventory, and the import volume remains high in September. The futures price fluctuates between trading the current high inventory and weak basis and the expectation of overseas gas restrictions in the future. Attention should be paid to the inventory inflection point [19]. Urea Industry - The futures price of urea has rebounded, mainly due to short - covering driving the improvement of low - end spot transactions, rather than the substantial improvement of supply and demand. Device restart has brought the daily output back above 190,000 tons, and there will be further increments in the future, so the supply pressure continues to accumulate. On the demand side, it is the off - season for agriculture, the industrial demand is rigid, and the export is marginally weakening. The fundamentals do not provide continuous upward momentum. This rebound is more of a result of capital game and sentiment repair, and the upward height is limited by the dual pressures of supply expansion and export profit contraction. Attention should be paid to the restart and maintenance implementation rhythm of devices such as Henan Xinlianxin and Shanxi Tianze [25]. Benzene - Styrene Industry - For pure benzene, due to the unplanned maintenance of a reforming device in East China, the supply in September is lower than expected. On the demand side, most downstream products are in a loss state, and some products' secondary downstream inventories are high. In addition, the maintenance plan of downstream styrene devices increases from September to October, so the demand - side support weakens. The supply - demand of pure benzene in September is still expected to be relatively loose, and the price driving force is weak. However, in the short term, with the strong oil price and the improvement of the domestic commodity macro - atmosphere, the price center of pure benzene is expected to be supported. For styrene, the overall operating rate of downstream 3S has declined. Some styrene devices are under planned maintenance, and some have reduced their loads due to accidents, resulting in a continuous decline in the high - level port inventory. With the short - term strong oil price, the driving force of styrene is expected to strengthen, but the rebound space is still limited by the high port inventory [30]. 3. Summaries According to Relevant Catalogs Polyolefin Industry - **Price Changes**: The closing prices of L2601, L2509, PP2601, and PP2509 all increased, with increases of 0.88%, 3.11%, 0.77%, and 2.65% respectively.
