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]. Polyester Industry Chain - For PX, supply is increasing to a relatively high level, and short - term demand has some support, but the upside is limited. It is expected to fluctuate between 6600 - 6900 in the short term [30]. - PTA's spot market liquidity is good, and the medium - term supply - demand is weak. It is expected to fluctuate between 4600 - 4800 in the short term, and TA1 - 5 should be rolled in a reverse spread [30]. - Ethylene glycol's supply - demand pattern is strong in the near - term and weak in the long - term. It is expected to reduce inventory in September but increase inventory in the fourth quarter. It is recommended to wait and see on the single - side and use EG1 - 5 reverse spread [30]. - Short - fiber's short - term supply - demand is weak, and it mainly follows raw material fluctuations. The single - side strategy is the same as PTA, and the processing fee is expected to fluctuate between 800 - 1100 [30]. - Bottle - chip's supply increases slightly, and demand may decline. It mainly follows cost fluctuations, and the processing fee is expected to fluctuate between 350 - 500 yuan/ton [30]. Pure Benzene - Styrene Industry - Pure benzene's supply is at a relatively high level, and demand is weak. It is expected to be supported by the strong oil price and good macro - atmosphere, and BZ2603 should follow styrene to fluctuate strongly [35]. - Styrene's price is strongly supported but the upside is limited by high port inventory. EB10 should be bought at low prices, and the EB11 - BZ11 spread should be widened at low levels [35]. Urea Industry - Urea futures have rebounded in the past two days, driven by supply - side maintenance expectations. Demand is mainly supported by export and industrial needs, and the futures increase is mainly due to short - covering and expectation differences [39][40]. Methanol Industry - Methanol's supply in the inland is at a high level, and demand is weak due to the traditional off - season. 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. It is recommended to wait and see on the single - side, and look for opportunities to widen spreads on the options side after volatility increases [48] Summary by Directory Chlor - Alkali Industry - **PVC, Caustic Soda Spot & Futures**: On September 16, Shandong 32% liquid caustic soda's price decreased by 3.0%, and Shandong 50% liquid caustic soda's price decreased by 4.4%.
