Market performance varies due to different demand situations [2] - The price of pure benzene is weakly operating, but there may be improvements in the third - quarter supply - demand situation. The price of styrene has certain support [3] - In the polyester industry, PX and PTA prices are related, and the demand for polyester products shows a positive trend, but there are also issues such as high inventory [5] - The methanol market may stabilize after a weak period, while the urea market is expected to remain weak [6] - The PVC market is under supply pressure and may decline, and the caustic soda market will likely fluctuate widely [7] - The soda ash market may be short - sold at high prices, and the glass market is expected to fluctuate widely [8] Summary by Related Catalogs Olefins - Polyolefins - Propylene futures fluctuate narrowly around the 5 - day moving average, with tight supply and strong downstream demand. Polyolefin futures are in a low - level range, with stable supply but slow demand growth [2] Pure Benzene - The price of pure benzene fluctuates above 6000 yuan/ton, with increasing supply and demand, and a weak price due to factors such as poor downstream profitability. The price of styrene has certain support due to device maintenance [3] Polyester - PX price rebounds, PTA follows up slightly, and the demand for polyester products is improving, but there are issues such as high inventory. Ethylene glycol has a strong basis, and short - fiber can be considered for long - position allocation [5] Coal Chemical Industry - The methanol market may stabilize after a weak period, with port inventory accumulation and expected demand improvement. The urea market is expected to remain weak due to factors such as high inventory and weak demand [6] Chlor - alkali Industry - PVC has supply pressure and may decline due to new device production. Caustic soda has a differentiated performance in different regions and is expected to fluctuate widely [7] Soda Ash - Glass - Soda ash supply is slightly reduced, and the market may be short - sold at high prices. Glass production capacity is increasing slightly, and the price may fluctuate widely [8]

Report Title - PX & PTA & MEG Strategy Report for September 2025 [1] Report Industry Investment Rating - Not provided in the given content Core Viewpoints - PX supply is expected to reach a high level in September, with short - process MX being abundant and new MX production adding to PX output. However, downstream TA maintenance is increasing, and with the continuous compression of TA processing fees, TA devices may have further maintenance. Thus, PX fundamentals are weak, and it may show a weak and volatile trend without significant crude oil fluctuations [150]. - For PTA, although the polyester operating load is rising and the fundamentals are improving, the price performance is weak, and the TA processing fee is still compressed below 200 yuan/ton. The "Golden September and Silver October" demand is facing challenges, with increasing external tariff risks. The TA price is expected to have support and show an overall volatile trend [150]. - MEG's operating load has climbed to a high level. In September, there are both maintenance and restart of devices. The port inventory is low, and the spot liquidity is tight. With supply contraction and demand increase, the port inventory is expected to remain low, and the short - term price may be volatile and strong [150]. Summary by Relevant Catalogs 1. PX&PTA&MEG Price: Follow Crude Oil Price Oscillation - **Futures Prices**: From July 31 to August 28, 2025, PTA futures closing price decreased from 4808 yuan/ton to 4792 yuan/ton (-0.3%), MEG increased from 4414 yuan/ton to 4465 yuan/ton (1.2%), and PX decreased from 6928 yuan/ton to 6886 yuan/ton (-0.6%) [6]. - **Basis and Spread**: For PTA basis, it changed from - 17 yuan/ton to - 20 yuan/ton (-17.6%); MEG basis changed from 71 yuan/ton to 64 yuan/ton (-9.9%); PX basis changed from 188 yuan/ton to 97 yuan/ton (-48.6%).
