Core Viewpoint - PTA is currently supported by cost factors, with market focus on the execution of maintenance schedules and the recovery of export orders. The polyester futures prices are expected to remain supported due to cost boosts, domestic "anti-involution" policies, and improved export expectations from India [1] Cost Support - Cost support remains strong, with expectations of oversupply in oil from Q4 to Q1 next year, leading to a weak and fluctuating international oil price. The transmission of oil price changes to downstream industries is relatively mild due to low PTA processing fees [2][3] PX Supply and Demand - Domestic PX operating rates have slightly decreased to 86.8%, a drop of 3 percentage points. Asian PX operating rates are at 78.5%, down 1.7 percentage points. Several PX facilities in Asia are undergoing maintenance, tightening the PX spot market supply. The overall PX supply-demand balance is improving, supporting PTA costs [6] Inventory Pressure - PTA social inventory is approximately 3.1561 million tons, showing a slight accumulation. The inventory structure is reasonable, with polyester factories maintaining raw material stock for 13-14 days. The overall inventory level is lower than in the past two years, indicating limited inventory pressure [8] PTA and Polyester Production - By 2025, PTA production capacity is expected to reach 91.715 million tons, with a growth rate of 9.5%. The polyester industry is projected to maintain a high average operating rate of 88.29%, providing rigid demand support for PTA. However, weak weaving orders may lead to reduced purchasing intentions among polyester companies [11][13] Market Dynamics - The PTA market is currently facing a balance between cost support and demand suppression, with prices expected to fluctuate between 4500 and 4900 yuan per ton [11][13]

Core Viewpoint - PTA is currently supported by cost factors, with market focus on the execution of maintenance schedules and the recovery of export orders. The polyester futures prices are expected to remain supported due to cost boosts, domestic "anti-involution" policies, and improved export expectations from India [1] Group 1: Cost Support - The oil supply surplus is expected to be strong from Q4 to Q1 next year, leading to a weak and fluctuating international oil price. The low PTA processing fee results in a mild transmission of oil price changes to downstream industries [2] - The domestic PX operating rate has slightly decreased to 86.8%, down 3 percentage points week-on-week, while the Asian PX operating rate is at 78.5%, down 1.7 percentage points. This decline in operating rates is due to maintenance activities, leading to tight PX spot market supply [4] Group 2: Inventory Pressure - The total PTA production capacity is projected to reach 91.715 million tons by the end of 2025, with a capacity growth rate of 9.5%. Recent new capacities have led to a relatively loose spot liquidity [5] - PTA social inventory is approximately 3.1561 million tons, showing a slight accumulation. The inventory structure is reasonable, with polyester factories maintaining raw material stock for 13-14 days. The overall inventory level is lower than the same period in the past two years [5] Group 3: Market Dynamics - The PTA industry operating rate has adjusted to 75.7%, while the polyester industry operating rate is at 90.5%. The overall supply-demand dynamics for PTA remain stable [7] - The polyester industry is expected to exceed 90 million tons in total production by 2025, with an average operating rate of 88.29%. However, the demand for polyester is showing signs of weakness, leading to a forecasted trading range for PTA contracts between 4500 and 4900 yuan/ton [8]

Summary by Relevant Catalogs 3.1 Olefins - Polyolefins - Propylene futures fluctuate widely around the 5 - day moving average. Low enterprise inventory supports prices, but downstream cost pressure and low international oil prices may drag down sentiment [2] - Plastic and polypropylene futures have narrow - range fluctuations. For polyethylene, cost support weakens, supply pressure is high, and demand is limited, so prices will be weak. For polypropylene, inventory is transferred to the middle - link, but downstream demand is poor, and the supply - demand contradiction persists [2] 3.2 Polyester - Falling oil prices but firm PX support PTA prices. PTA has increased device maintenance due to poor efficiency, and terminal demand is weakening. For ethylene glycol, supply pressure is high, and the market is expected to be bearish. Short fiber has no new investment pressure but demand is expected to weaken, and bottle chip demand is declining with over - capacity as a long - term issue [3] 3.3 Pure Benzene - Styrene - The narrowing of the US - South Korea aromatic hydrocarbon spread makes the market focus on Asian aromatic hydrocarbon outflows. Pure benzene prices rebound strongly, but the sustainability of exports to the US is to be observed. Styrene futures rise, with cost support from pure benzene and supply reduction and increased export demand [5] 3.4 Coal Chemical Industry - Methanol futures are in low - level oscillations. Overseas device operation is high, and demand is expected to be weak. Urea futures fluctuate narrowly. Agricultural demand is weakening, but industrial demand is picking up, and supply remains high [6] 3.5 Chlor - Alkali - PVC continues to decline due to weakened cost support. Although exports to India may improve, the overall demand boost is limited. Caustic soda is in a downward trend, with cost support insufficient and downstream demand weak [7] 3.6 Soda Ash - Glass - Soda ash continues to decline as the cost side moves down. The industry inventory decreases, and the supply - demand pattern is in surplus in the long - term. Glass also declines, with high intermediate - link inventory. Although cost support exists at the current price, it is recommended to wait and see [8]
