Report Summary 1. Report Industry Investment Rating No information provided in the content. 2. Core Viewpoints of the Report - OPEC+ plans to increase oil production by 548,000 barrels per day this month, and there are expectations for another 548,000 barrels per day increase in September, which may lead to an oversupply and downward pressure on oil prices. The US tariff agreements may improve market risk appetite, but the potential secondary tariffs on countries buying Russian oil could cause price fluctuations [4]. - PX is in a tight - balance situation with low inventory and high operating rates. With only one potential new device planned at the end of 2025 and high uncertainty, PXN has support due to new PTA device demand [4]. - A 3.2 - million - ton PTA device in East China has one line put into production, and multiple devices are under maintenance. The short - term polyester load is strong, but in the long run, there is an oversupply, and prices are expected to fluctuate with the cost [4]. - Rising coal prices support the cost of ethylene glycol. Port inventory is decreasing, and the supply - demand is tight. However, there is an expected increase in imports in August, and short - term prices are expected to be strong [4]. - The average weekly capacity utilization rate of the Chinese polyester industry is 85.82%, down 0.60% week - on - week. Downstream demand is weak, and the industry is in an oversupply situation. The demand for textile raw materials is expected to recover in mid - to late August [26]. 3. Summary by Related Catalogs Crude Oil - OPEC+ is set to increase production by 548,000 barrels per day this month, and there are expectations for the same increase in September, which may lead to oversupply and downward price pressure. The US tariff agreements may improve market risk appetite, but the claim of secondary tariffs on countries buying Russian oil could cause price fluctuations [4]. PX - Current PX inventory is low, and the operating rate is high, maintaining a tight - balance situation. In 2025, only one 3 - million - ton device of Yulong Petrochemical is expected to be put into operation at the end of the year, with a capacity growth rate of about 5%. The domestic PX output in the first half of 2025 was 18.3 billion tons, a year - on - year increase of 2.7%. The annual supply in 2025 is expected to be about 47.8 billion tons, with a growth rate of about 3%. The domestic weekly average PX capacity utilization rate is 82.35%, down 0.56% week - on - week, and the Asian weekly average is 71.98%, down 0.03% week - on - week. The PX - naphtha spread is around $265 per ton. The downstream PTA is still in an expansion cycle, and the supply - demand gap supports PX prices [4][8]. PTA - A 3.2 - million - ton PTA device in East China has one line put into production recently, and multiple devices are under concentrated maintenance. The downstream polyester is in the off - season, and the processing fee is 204 yuan per ton, remaining flat compared to last week and at a low point this year. With new device production, the oversupply situation will intensify, and the processing fee may be compressed. The weekly average PTA capacity utilization rate is 79.67%, down 1.09% week - on - week. The spot market price is 4,750 yuan per ton, and the mainstream spot basis is 09, - 13 [4][14]. MEG - The market price of ethylene glycol this week is 4,485 yuan per ton, down 2.05% week - on - week. The total domestic ethylene glycol capacity utilization rate is 60.67%, up 1.47% week - on - week, and the coal - based capacity utilization rate is 63.87%, up 3.88% week - on - week. The gross profit has risen to 103.33 yuan per ton, up 15.42 yuan per ton week - on - week. The inventory in East China ports is 427,200 tons, down 47,800 tons week - on - week, at a historical low. Due to the delay of imported goods caused by typhoons, imports are expected to increase. Affected by coal prices, the overall price is expected to be strong [19]. Polyester Industry - The average weekly capacity utilization rate of the Chinese polyester industry is 85.82%, down 0.60% week - on - week. Downstream demand is weak, and there is inventory accumulation due to high - level operation. The effectiveness of potential production cuts needs further observation. The demand for long - and short - fiber textile raw materials is expected to recover in mid - to late August [26].
