The expected pressure of supply glut has not been reflected in the market, and oil prices were stagnant during the Asian session. The CFR China price of PX on September 25 was $817 per ton, and international oil prices continued to rise due to the decline in US crude oil inventories. The domestic PX operating load was stable, and the demand side was waiting for the implementation of the expected changes in PTA plants. The cost support led to a slight price recovery. The PX2511 contract closed at 6,674 yuan per ton (up 1.61%), with a trading volume of 185,500 lots. The increase in PX supply due to the increase in short - process production at home and abroad and the postponement of some plant maintenance was obvious, while the demand for PX decreased more than expected due to the delay of new PTA plant commissioning and multiple PTA plant maintenance. The supply - demand situation did not change significantly, and the PX profit would remain low in the short term [2] - **PTA**: The cost support slightly recovered, and the TA2601 contract closed at 4,678 yuan per ton (up 1.74%), with a trading volume of 701,000 lots. The sales of polyester filament on Wednesday evening were around 149% and 175% on Thursday, which was positive for the PTA market. The cost support was strengthened, and there was a strong expectation of PTA plant maintenance due to low processing fees. The leading polyester factories adjusted the production rhythm to stabilize market supply, but the production enterprises faced great pressure to sell at the end of the month. The new orders of weaving enterprises improved, and the shipment speed of grey cloth continued to improve, but the overall inventory pressure in the grey cloth market still existed, leading to the lack of confidence of downstream enterprises in the future market. As the National Day holiday approached, the sentiment in the downstream market was clearly divided, and some enterprises expected the market to improve after the holiday [2] - **PR**: The mainstream negotiation price of polyester bottle chips in the Jiangsu - Zhejiang market was 5,800 - 5,900 yuan per ton, up 55 yuan per ton from the previous trading day. The prices of PTA and bottle - chip futures rose, and the supply - side quotation of bottle chips mainly increased, but the purchasing enthusiasm of downstream terminals was not high, and the trading atmosphere was light. The PR2511 contract closed at 5,840 yuan per ton (up 1.46%), with a trading volume of 28,600 lots. The operating rate of the bottle - chip industry was expected to gradually recover, and the market supply of goods was relatively abundant. The purchasing intention of downstream terminals was not high, and the market trading atmosphere was light [2] Production and Sales and Operating Conditions - **Operating Conditions**: On September 25, 2025, the operating rate of the PX in the polyester industry chain was 85.57%, unchanged from the previous value; the load rate of PTA plants in the PTA industry chain was 78.12%, unchanged; the load rate of polyester plants was 87.81%, up 0.08 percentage points; the load rate of bottle - chip plants was 69.37%, up 0.27 percentage points; the load rate of Jiangsu - Zhejiang looms was 69.19%, up 1.64 percentage points [1] - **Production and Sales**: On September 25, 2025, the sales rate of polyester filament was 175.16%, up 94.51 percentage points from the previous value; the sales rate of polyester staple fiber was 88.58%, up 21.54 percentage points; the sales rate of polyester chips was 152.51%, up 9.03 percentage points [1]

1. Report Industry Investment Rating - No relevant information provided 2. Core Views of the Report - This week, the PX price rose and then retraced. The absolute price on Friday was down 0.9% week - on - week to $849/ton CFR, but the weekly average price still increased slightly by 1.4% to $855/ton CFR. The PX inventory is at a historical low, providing strong support at the bottom. Whether the PX profit can continue to improve depends on more unexpected factors. PX is in an advantageous position in the industrial chain, and its social inventory is decreasing due to the rigid demand of new PTA production facilities. As the downstream demand peak season approaches, polyester production is gradually recovering [2]. - The PTA spot supply is sufficient, and the spot basis is weakening, which is negative for market sentiment. The PTA processing fee has entered a low - range, and unplanned device maintenance is difficult to continuously boost the price. As the traditional peak season approaches, the polyester production load may increase, and the de - stocking volume is expected to expand. The terminal demand is still weakly recovering, but the downstream's bullish expectation has increased. The industrial chain profit is shifting towards the raw material segment, and PTA will move in a volatile manner with cost as the dominant factor [2]. - The polyester bottle - chip market in Jiangsu and Zhejiang is trading at 5880 - 6030 yuan/ton, down 5 yuan/ton from the previous trading day. The bottle - chip supply side has a stable - to - falling price offer, and the downstream is cautious. The overall production reduction of the supply side has not changed significantly, and the market spot supply is abundant [2]. - Currently, the pricing logic is still cost - driven. It is expected that PX, PTA, and PR will operate in a volatile manner [2]. 3.
