Report Overview - Report Name: Polyester Data Weekly Report - Date: September 28, 2025 - Analyst: He Xiaoqin, Qian Jiayin 1. Investment Rating - The report does not mention the industry investment rating. 2. Core Views - The overall trend of PX, PTA, and MEG remains weak. Suggest 1 - 5 inverse spreads for these products. For PTA, consider shorting on the rebound of processing fees for 01/05 contracts. For MEG, operate within the range of 4000 - 4400 and consider the strategy of going long on L and short on MEG [3][4][6][7][9]. 3. Summary by Product PX Valuation - The PX valuation is affected by factors such as the strengthening of naphtha, the weakening of PXN, and the strong overseas oil product cracking spreads. The external PX is strong in the near - term, and attention should be paid to the monthly spread inverse spread [20][28][34]. Supply and Demand - Domestic PX supply is gradually increasing. The domestic PX operating rate is 86.7% (+0.4%), and the Asian PX operating rate is 78% (-0.2%). In August, the PX表观 consumption was 393000 tons, and the import volume was 88000 tons, a month - on - month increase of 10000 tons. The inventory in August decreased to 3.9 million tons (-240000) [55][56][57][60][67][73]. PTA Valuation - The 1 - 5 month spread is in an inverse spread. The PTA processing fee is at a low level, and the device operation willingness is weakened. The cost has collapsed, the price has dropped significantly, and the basis has declined [79][81][87]. Supply and Demand - The PTA supply is gradually increasing. The current operating rate is 76.8% (unchanged). The cumulative PTA production from January to August 2025 was 48.11 million tons, a year - on - year increase of 3.56%. Exports increased from July to August, and the inventory is at a low level [90][93][106]. MEG Valuation - The MEG valuation shows a downward trend, and the basis remains high. The MEG is relatively more valuable compared to ethylene oxide, styrene, and plastics. The coal - based profit has dropped to 305 yuan/ton (-95), the naphtha - based MEG profit is -970 (-130) yuan/ton, and the MTO profit is -1106 (-70) yuan/ton [123][129][131]. Supply and Demand - The overall operating load of MEG in the Chinese mainland is 73.08% (a month - on - month decrease of 1.85%), and the operating load of oxalic acid catalytic hydrogenation (syngas) to produce MEG is 74.36% (a month - on - month decrease of 5.02%). The supply pressure has marginally improved. The import volume in August was about 590000 tons, and it is expected to increase in September. The port inventory is at a low level [133][136][137]. Polyester - The current polyester operating rate is 90.3% (-1.3%). Affected by the typhoon, a 1.1 - million - ton bottle - chip factory in South China temporarily stopped production. The bottle - chip sales improved significantly, the filament factory's promotion drove the inventory to decrease by 7 - 10 days, and the staple fiber inventory continued to decline. However, in the medium - to - long - term, the inventory pressure of polyester factories is expected to rise again after the festival [158][160].
