Report Summary 1. Report Industry Investment Rating No information provided in the given content. 2. Report's Core Views - **PTA**: Near - end TA maintenance is over, and the start - up rate has increased. Polyester load has slightly risen, inventory is stable, the basis is weak, and spot processing fees are at a low level. PX domestic start - up has increased, and overseas plants have restarted. In the future, TA de - stocking will slow down, and long - term inventory accumulation is expected. However, processing fees are extremely low and have lasted for a long time. With the gradual return of PX supply, attention should be paid to the opportunity to expand processing fees under potential additional maintenance [1]. - **MEG**: Near - end domestic oil - based EG is stable, coal - based start - up has slightly increased, and overall load has recovered. Overseas, there are both maintenance and restarts. Port inventory has slightly accumulated. Downstream stocking levels have increased, the basis has weakened, and the benefit ratio has shrunk. New EG devices are put into operation earlier than expected, and valuations are significantly compressed. In the future, ports may start to gradually accumulate inventory, but the current inventory is not high, and valuations may be slowly compressed. Attention should be paid to the cost support of coal - based production [6]. - **Polyester Staple Fiber**: Near - end plants such as Sanfangxiang and Yizheng have increased their loads, and the start - up rate has reached 94.4%. Production and sales have improved, and inventory has slightly decreased. On the demand side, the start - up rate of the polyester yarn end is stable, raw material stocking has decreased, and finished product inventory has decreased. In the future, the rate of increasing the load at the polyester yarn end may slow down. The start - up rate of staple fiber is expected to remain high due to good spot benefits, and inventory pressure is limited. Processing fees are expected to fluctuate [6]. - **Natural Rubber**: National explicit inventory is stable, and the price of Thai cup lump rubber is stable. Rainfall has affected rubber tapping [6]. 3.

1. Report Industry Investment Rating No information provided in the documents. 2. Core Views of the Report - PTA: The start - up of PTA devices has rebounded slightly, polyester load has increased, inventory has continued to decline, basis has weakened month - on - month, and spot processing fees have declined. PX domestic start - up is stable, overseas devices are restarted, PXN has weakened month - on - month. Although TA inventory continues to decline, its structure and efficiency are still weakening. Considering the lack of unexpected performance in polyester and subsequent new production, there is an expectation of inventory accumulation in the far - month. However, the processing fee has reached a very low level, and PX supply is gradually recovering. One can pay attention to the opportunity of expanding the processing fee at low prices [1]. - MEG: Recently, domestic oil - based production has increased the load, coal - based start - up has slightly declined, the overall load has decreased, overseas maintenance has increased. At the beginning of the week, port inventory continued to decline, and the arrival of goods within the week has rebounded. Downstream inventory levels have decreased, and the basis has strengthened month - on - month. There is an expectation of inventory accumulation in the far - month due to the return of maintenance and the commissioning of new devices. The pattern is not bad, and the profit level is also considerable. It is expected to fluctuate in a relatively wide range. One should pay attention to the restart progress of Satellite and Xinrun [8]. - Polyester Staple Fiber: Recently, the start - up of Xin凤鸣, Times Hollow, and Zhongtai has increased, and the start - up rate has reached 93.9%. Sales have weakened month - on - month, and inventory has remained stable month - on - month. On the demand side, the start - up of the polyester yarn end has slightly increased, raw material inventory has rebounded, and finished product inventory has continued to accumulate, with weak efficiency. In the future, the start - up rate of the polyester yarn end may slow down after the accumulation of finished product inventory. It is expected that the start - up will remain high under the good spot efficiency of staple fiber, and the processing fee is expected to fluctuate [8]. - Natural Rubber: The national explicit inventory remains stable at an absolute level, and the price of Thai cup rubber remains stable. The strategy is to wait and see [8]. 3.

Group 1: Report Industry Investment Rating - Not provided in the content Group 2: Core Viewpoints of the Report - The supply reduction supports the price resilience of PTA, and its driving force depends on the terminal volume. The polyester industry chain presents a demand - driven repair, with PX - PTA prices likely to enter a bottom - oscillation stage. The inventory pressure of polyester staple fiber and some filament varieties still needs continuous terminal volume to digest, while POY has more price elasticity due to healthy inventory [2][7] Group 3: Summary by Relevant Catalogs 1. Daily Market Summary PTA & PX - On September 10, the PX main contract closed at 6,770.0 yuan/ton, up 0.65% from the previous trading day, with a basis of - 149.0 yuan/ton. The PTA main contract closed at 4,698.0 yuan/ton, up 0.43% from the previous trading day, with a basis of - 88.0 yuan/ton. The Brent crude oil main contract closed at 66.53 dollars/barrel, and WTI at 62.77 dollars/barrel. The total transaction volume of the Light Textile City was 702.0 million meters, with a 15 - day average transaction of 662.8 million meters [2] - On the supply side, there is a short - term tightening expectation for PX supply. The PX plant operating rate has decreased slightly, and the PTA load has dropped, which may force PX manufacturers to adjust the operating rate. For PTA, some large - scale plants have entered maintenance, and the overall industry load has dropped below 75%, which may support the PTA price [3] - On the demand side, the polyester demand still has resilience, but the risk of marginal weakening increases. The current polyester operating rate remains at a high level of 89%, but attention should be paid to the continuous accumulation of terminal grey fabric inventory and the fading of the pre - effect of European and American autumn and winter orders, which may suppress the subsequent replenishment momentum [4] - On the inventory side, the de - stocking intensity of PTA factories is a key variable. Although the absolute value of social inventory is still at the median level in the past three years, the available inventory days have decreased from 4.5 days to 3.8 days (a month - on - month decrease of 15.6%), indicating a marginal relief of inventory pressure. If the downstream stocking demand is released later, the PTA price center may move up [5] Polyester - On September 10, the short - fiber main contract closed at 6,364.0 yuan/ton, up 0.19% from the previous trading day. The spot price in the East China market was 6,465.0 yuan/ton, up 5.0 yuan/ton from the previous trading day, with a basis of 101.0 yuan/ton [6] - The current supply - demand pattern of the polyester industry chain is differentiated but generally stable. On the supply side, the prices of PX and PTA futures have declined, indicating loose supply or weakened cost support. On the demand side, the MA15 data of the China Light Textile City's trading volume has increased by 17% from September 1 to September 10, indicating a recovery in terminal weaving demand. On the inventory side, the inventory of polyester staple fiber is 6.97 days, far exceeding the five - year average of 4.96 days. Among filament varieties, the inventories of FDY (26.4 days) and DTY (29.7 days) are also higher than the historical averages, while the POY inventory of 17.4 days is lower than the historical center [6] 2.

Appendix: Big Model Inference Process - Analyze the future price trends of PTA and PX from three dimensions: supply, demand, and inventory. On the supply side, the price increases of PX and PTA main contracts may indicate supply tightness, and the impact of crude oil price trends on PX cost needs to be considered. On the demand side, the trading volume data of the Light Textile City is crucial. High trading volume may indicate increased demand for PTA. On the inventory side, although the PTA factory inventory data is missing, the basis and price trends can be used to infer the inventory level. Finally, comprehensively analyze the three aspects to predict the future price trends of PTA and PX [38][39][40]

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints - OPEC+ plans to increase production, leading to a significant drop in crude oil prices. Domestic PTA plants are gradually resuming operations, resulting in a rise in PTA production and a rapid decline in PTA basis. The spread between PX and naphtha remains stable. With the recent improvement in sales and inventory reduction, especially the significant reduction in filament inventory, downstream profits have been significantly restored, and the operating load of polyester has rebounded to 91%.
