Report Summary Core Viewpoints - PTA: Domestic PTA installations are gradually resuming, leading to an increase in domestic PTA production. The PTA basis has declined rapidly, and the market is under significant pressure due to Hengli's concentrated sales. OPEC+ has increased oil production again, causing a sharp drop in crude oil prices. The spread between PX and naphtha has narrowed. With recent weakening sales and rising inventories, especially as the off - season approaches, the polyester operating load has risen to 91%. However, due to the decline in crude oil prices and the weakening basis, PTA has shown weak performance [2]. - Ethylene Glycol (MEG): The inventory of ethylene glycol at East China ports is 46.5 million tons. The weekly port arrivals are still limited, and the shipping volume from the main warehouse in Zhangjiagang continues to increase, resulting in a continuous decline in the overall ethylene glycol inventory. The ethylene glycol port is expected to continue destocking. Although the import of ethylene glycol in the overseas market is expected to decline, the commissioning of domestic installations has continuously pressured the ethylene glycol price. Coal - based ethylene glycol installations are also resuming. The overall polyester inventory is in good condition, and the downstream weaving load has increased [2].

Industry Operating Rates - PX operating rate remained at 85.57%, PTA operating rate was stable at 79.38%, MEG operating rate stayed at 62.62%, and polyester load remained at 89.00% [2]. Sales and Production Ratios - The sales - to - production ratio of polyester filament increased from 38% to 80%, and the sales - to - production ratio of polyester staple fiber increased from 48% to 67%, and the sales - to - production ratio of polyester chips increased from 58% to 143% [2]. Device Maintenance - Two PTA installations in South China with a total capacity of 500 million tons have reduced their loads recently due to weather conditions, and the recovery time is to be tracked [2].
