1. Report Industry Investment Rating - No relevant content found. 2. Core Views of the Report PTA - Yesterday, PTA futures fluctuated and declined. The spot market negotiation atmosphere was average, and the spot basis was weak with differentiation. Polyester factories' bids increased. The mainstream spot basis today is at 01 - 51. The PTA device maintenance effect was less than expected, the spot market liquidity was okay, the spot basis weakened, and the price fluctuated following the cost side. Although the processing margin improved slightly from the low point, it remained at a relatively low level. Attention should be paid to the maintenance situation of Hengli Huizhou's device and subsequent upstream and downstream device changes [5]. - The spot price is 4700, the 01 - contract basis is - 32, and the futures price is at a premium, which is neutral. The PTA factory inventory is 3.81 days, a 0.1 - day increase compared to the previous period, which is bearish. The 20 - day moving average is downward, and the closing price is below the 20 - day moving average, which is bearish [6]. MEG - On Wednesday, the price of ethylene glycol (MEG) was consolidating at a low level, and the market negotiation was okay. The intraday MEG futures were weakly consolidating. The spot negotiation was traded at a premium of 86 - 92 yuan/ton to the 01 contract. Some contract merchants and suppliers participated in restocking, and the spot basis moderately strengthened at the end of the session. In terms of US dollars, the overseas MEG price was consolidating at a low level. The early - morning negotiation price for near - term shipments was around 524 - 525 US dollars/ton, and the afternoon negotiation price dropped to around 520 - 522 US dollars/ton. The 9 - end - of - September shipments were traded at around 519 - 523 US dollars/ton, and some financing merchants participated in inquiries [7]. - The spot price is 4434, the 01 - contract basis is 103, and the futures price is at a discount, which is bullish. The total inventory in East China is 40.63 tons, a 9.42 - ton decrease compared to the previous period, which is bullish. The 20 - day moving average is downward, and the closing price is below the 20 - day moving average, which is bearish. The arrival volume in early September is still moderately low, and there is still some room for a moderate decline in ports in the short term. In terms of demand, it is expected that the average load in September can reach 91.5%. The rigid demand support is gradually improving. Recently, the commodity market has corrected, and the MEG futures have been under pressure. It is expected that the price of MEG will mainly consolidate within a range in the short term, with strong support at the bottom. Subsequent attention should be paid to device changes and polyester load changes [7][8]. Influencing Factors - Bullish factors: In August, some PTA devices were scheduled for maintenance, improving supply - demand expectations. As the traditional "Golden September and Silver October" peak season approaches, the market has shown some expectations for demand recovery. Yisheng Hainan's 2 million - ton device stopped for maintenance, and Hengli Huizhou's 2.5 million - ton device had an unscheduled shutdown [11]. - Bearish factors: The profit margins of all links in the industrial chain continue to be under pressure, and the overall operating atmosphere remains cautious [10]. Current Main Logic and Risk Points - The short - term commodity market is greatly affected by the macro - level. Attention should be paid to the cost side. For the futures price rebound, attention should be paid to the upper resistance level [10]. 3. Summary by Relevant Catalogs 1. Previous Day's Review - No relevant content found. 2.

Profit - Related Data - There are data on PTA processing fees, MEG production margins from different production methods, and production margins of polyester fibers [61][62][65].

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.
