Report Summary 1) Report Industry Investment Rating - No information provided. 2) Core Viewpoints - The PTA market had limited overall fluctuations, with sufficient spot supply, a weakening spot basis, and a slight decline in prices. The expansion of the spread between PX and naphtha and the weak benzene price restricted the further increase in PX production. With the improvement in recent sales and inventory reduction, especially the significant reduction of filament inventory, profits were significantly repaired, but some downstream devices had strong maintenance expectations [2]. - The ethylene glycol price rebounded. The planned production cut of South Korean naphtha cracking units and the continuous postponement of the maintenance of overseas ethylene glycol units, especially Saudi Arabian units, would have a significant impact on the market outlook, boosting the ethylene glycol price. The later arrival volume of ethylene glycol decreased, polyester inventory was in good condition, and the downstream weaving load increased [2]. 3) Summary by Relevant Catalogs Market Data - INE crude oil price decreased from 485.2 yuan/barrel on August 29, 2025, to 483.5 yuan/barrel on September 1, 2025, a decrease of 1.70 yuan/barrel.

1. Report Industry Investment Rating - Not provided in the given content 2. Core View of the Report - The supply - demand pattern of polyester raw materials has improved, and with cost support, prices are likely to rise and difficult to fall. The polyester industry chain is expected to remain relatively strong in the short term, but the fulfillment of peak - season demand needs to be monitored [1][4] 3. Summary by Relevant Catalogs 3.1 Daily Market Summary PTA & PX - On August 25, the PX main contract closed at 6,970.0 yuan/ton, up 0.06% from the previous trading day, with a basis of - 147.0 yuan/ton. The PTA main contract closed at 4,862.0 yuan/ton, down 0.12% from the previous trading day, with a basis of 8.0 yuan/ton. The Brent crude oil main contract closed at 67.26 US dollars/barrel, and WTI closed at 63.77 US dollars/barrel. The total transaction volume of the Light Textile City was 541.0 million meters, with a 15 - day average transaction of 504.67 million meters [2] - On the supply side, PX device load has increased due to the weakening demand for aromatic hydrocarbon blending oil, and there may be复产 pressure on Asian devices in the fourth quarter. PTA has unexpected maintenance currently, but there is an expectation of restart and output increase in September. On the demand side, weaving orders and Light Textile City transactions have seasonally improved, but the year - on - year growth rate is still low, and the sustainability of terminal orders needs verification. The high polyester operating rate depends on speculative restocking caused by raw material price fluctuations. On the inventory side, PTA factory inventory has reached a high level, and the deep basis discount reflects loose spot circulation. Downstream polyester raw material inventory days are in a neutral range, and there is a risk of implicit inventory turning into explicit inventory [3] Polyester - On August 25, the short - fiber main contract closed at 6,596.0 yuan/ton, down 0.27% from the previous trading day. The spot price in the East China market was 6,585.0 yuan/ton, down 15.0 yuan/ton from the previous trading day, with a basis of - 11.0 yuan/ton [3] - From August 15 to August 25, PX and PTA prices both increased, indicating stronger cost support or tighter supply. The Light Textile City MA15 transaction volume fluctuated between 480 - 505 million meters, showing weak terminal demand. The inventory pressure of the polyester industry chain is mainly concentrated in the short - fiber segment. The polyester industry chain is expected to remain strong in the short term, and the fulfillment of peak - season demand needs attention [4] 3.2 Industrial Chain Price Monitoring - For PX, on August 25, the main contract price was 6,970 yuan/ton, up 0.06% from August 22; the main contract trading volume decreased by 8.85%; the main contract position increased by 3.14%.

Core Viewpoint - The polyester sector has experienced a rebound since August 15, driven by multiple factors including stable oil and coal prices, low inventory levels of key raw materials, and an approaching demand peak season [1][2]. Group 1: Market Dynamics - The recent price increase in the polyester sector is supported by stable oil and coal prices, which have rebounded, and the sector's long-term low valuation limits further downside potential [1]. - The inventory levels of key raw materials such as PX, PTA, and MEG are currently low, which, combined with the upcoming demand peak season, provides strong upward price elasticity if unexpected positive factors arise [1]. - The demand side is transitioning from a low to a high season, with weaving operating rates recovering to 63% and polyester operating rates increasing to 89.4% [2]. Group 2: Supply Chain Insights - The polyester industry is currently in a phase of orderly expansion, with upstream production of PX and short fibers being paused, while PTA and bottle-grade PET continue to see rapid capacity growth [2][3]. - The overall profit levels in the polyester supply chain remain low, with profits concentrating in the upstream due to differing production rhythms across the supply chain [2][3]. Group 3: Future Outlook - The current trading logic in the polyester sector reflects a contradiction between strong realities and weak expectations, with concerns about demand being dragged down by earlier "export rush" activities [3]. - Short-term expectations suggest that the polyester sector may experience a pattern of easy price increases but difficult declines, while long-term price strength will depend on cost stability, supply-demand dynamics, and macroeconomic sentiment [3]. - Analysts predict a generally strong price trend for polyester until September, with a focus on valuation changes and the actual impact of supply-side factors thereafter [3].

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The report analyzes the weekly performance of the polyester industry chain, including PX, PTA, MEG, polyester, and terminal products. It points out that the market is in a state of waiting for the peak season. Although there are some improvements in the terminal, the overall upstream valuation is still suppressed by the weak performance of the terminal and polyester. It also suggests paying attention to the opportunity of going long on dips following crude oil after the peak season [11][12][13]. 3. Summary According to Relevant Catalogs 3.1 Weekly Assessment and Strategy Recommendation - **PX**: Last week, the price fluctuated. The supply side saw an increase in load, with some domestic and overseas device changes. The demand side had a slight increase in PTA load, but the overall load in August decreased. The inventory continued to decline in July - August. The PXN fluctuated, and the valuation was at a neutral level. It is recommended to pay attention to the opportunity of going long on dips following crude oil after the peak season [11]. - **PTA**: The price also fluctuated last week. The supply side had an increase in load, but the overall load in August decreased due to more maintenance. The new device put into production increased the supply pressure. The demand side saw an increase in polyester load, and the terminal showed some improvement. The inventory continued to accumulate. The processing fee rebounded from a low level. It is recommended to pay attention to the opportunity of going long on dips following PX after the peak season [12]. - **MEG**: The price fluctuated last week. The supply side had a decrease in load, mainly due to the decline in ethylene - based load. The subsequent load is expected to increase. The demand side is similar to PTA. The inventory in ports and downstream factories increased. The valuation is relatively high, and there is a downward pressure on the short - term valuation [13]. 3.2 Futures and Spot Market - **PX**: The basis rebounded, and the spread was weak. The trading volume was small, and the open interest was stable [32][35]. - **PTA**: The basis was continuously weak, and the spread fluctuated.
