Some products are facing supply pressure and weak demand, while others have certain support from demand but also face future uncertainties [2][3][5] Summary by Category Olefins - Polyolefins - Olefin futures' main contracts fluctuated narrowly. Supply is controllable as restarting devices are not in place, and downstream demand provides some price support [2] - Polyolefin futures' main contracts also fluctuated narrowly. Polyethylene maintenance decreased with increased domestic production, and downstream has pre - holiday stocking demand but faces post - holiday de - stocking pressure. Polypropylene prices are under pressure due to multiple factors such as demand differentiation, supply pressure, and high inventory [2] Pure Benzene - Styrene - Pure benzene oscillated downward. Although the current fundamental situation is okay with port inventory decreasing and spot price being relatively firm, high import volume and expected demand decline drag the market [3] - Styrene futures' main contracts fluctuated narrowly. Cost - end oil price provides support, but high inventory suppresses the price [3] Polyester - PX's strong expectation weakened, and PTA's profitability is still poor. Although the pre - holiday stocking in the polyester yarn industry has reduced inventory pressure, post - holiday demand is expected to weaken, and the supply - demand situation remains under pressure [5] - Ethylene glycol's domestic operation decreased slightly, and port inventory is low. However, new device trials and weakening demand may lead to a weak supply - demand situation in the fourth quarter [5] - Short - fiber's new capacity is limited, and inventory decreased. The pre - holiday stocking has fulfilled the positive expectation. Bottle chips showed a short - term strong trend due to typhoon - affected device shutdown, but long - term over - capacity is a pressure [5] Coal Chemical Industry - Methanol's main contract oscillated. Port inventory is expected to increase after the holiday, and the market is expected to be weak [6] - Urea prices increased slightly, but downstream follow - up is cautious. The domestic supply - demand situation is loose, and attention should be paid to policy adjustments [6] Chlor - Alkali - PVC oscillated weakly with high supply and high inventory. Domestic downstream pre - holiday stocking intention is low, and foreign demand is weak [7] - Caustic soda's futures price oscillated under the weak situation. Although there is an expectation of downstream stocking before alumina production, the current supply is high [7] Soda Ash - Glass - Soda ash weakened. The industry is de - stocking, and the downstream pre - holiday stocking is nearly over. The long - term supply is in excess [8] - Glass prices fell from a high level. Some manufacturers plan to increase prices, and attention should be paid to downstream restocking sentiment [8]

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].
