Report Summary 1. Investment Rating No investment rating for the industry is provided in the report. 2. Core Views - The polyester industry chain is weak due to the continuation of the China - US game. The supply - demand imbalance is prominent, and the market is affected by factors such as crude oil price fluctuations, production capacity changes, and demand trends [2][3][5]. - For the strategy, it is recommended to cautiously short - sell PX/PTA/PF/PR on rallies for hedging, long PF processing fees at low levels, and conduct reverse spreads on PX/PTA2601 - 2605 [5][6]. 3. Summary by Directory Market News and Data - The Chinese Ministry of Commerce announced counter - measures against 5 US - related subsidiaries of Hanwha Ocean Co., Ltd. on October 14, 2025, in response to the US 301 investigation on China's maritime, logistics, and shipbuilding industries [1]. Market Analysis - **Cost Side**: During the China - US trade war, the leaders of both sides will meet around the end of the month. After the National Day, China's import demand slowed down while US exports increased, and Middle - East exports also rose, leading to an oversupply situation. Crude oil prices dropped sharply due to the renewed tariff war threat from the US, but there were some signs of easing later [2]. - **PX**: China's PX load has recovered to a relatively high level. With the restart of overseas units, the overall PX operation rate has increased. The postponement of PX maintenance plans in the fourth quarter and capacity expansion of some units have weakened the PX supply - demand outlook in the fourth quarter [2][5]. - **TA**: The PTA spot processing fee has been repaired but is still suppressed. The inventory accumulation rate has narrowed in October - November due to more maintenance plans and postponed new - unit launches, but there is significant inventory accumulation pressure in December [3][5]. - **Demand**: The polyester operating rate is 91.5% (unchanged from the previous period). The demand for filament yarn improved before the National Day, but the increase in polyester load is limited, and the sustainability of demand improvement needs attention [3]. - **PF**: The spot production profit is 300 yuan/ton (up 36 yuan/ton from the previous period). The inventory of direct - spun polyester staple fiber has decreased to a low level, and the short - term supply - demand situation is better than that of raw materials [4]. - **PR**: The spot processing fee of polyester bottle - grade chips is 509 yuan/ton (up 1 yuan/ton from the previous period). The inventory of domestic polyester bottle - grade chip factories has increased, and the supply - demand pressure is large under the pressure of new - unit launches [4]. Strategy - **Unilateral**: Cautiously short - sell PX/PTA/PF/PR on rallies for hedging [5]. - **Cross - Variety**: Long PF processing fees at low levels: PF2511 - 0.855PTA2601 - 0.332MEG2601 [6]. - **Cross - Period**: Conduct reverse spreads on PX/PTA2601 - 2605 [6].

1. Report Industry Investment Ratings No information about industry investment ratings is provided in the given reports. 2. Core Views of Each Report Methanol Industry - The methanol market has a relatively healthy inventory pattern due to high supply in the inland and continuous external procurement by some olefin plants, which supports prices. However, demand is weak due to the traditional off - season, and the overall valuation is neutral. The market is currently swaying between high inventory and weak basis in reality and the expectation of overseas gas restrictions in the future. Attention should be paid to the inventory inflection point [2]. Crude Oil Industry - Last week, oil prices oscillated, with the main trading logic being the continuous game between the supply - tightening expectation caused by geopolitical risks and concerns about weak macro - demand and supply surplus. In the short term, the market may continue to maintain a range - bound pattern in the tug - of - war between geopolitical risks and weak fundamentals. It is recommended to mainly adopt a wait - and - see approach for single - side trading, and a strategy of expanding spreads for option trading [7]. Chlor - Alkali Industry - For caustic soda, the spot price may stabilize, and the decline space of the futures price may be limited. Attention should be paid to the purchasing rhythm of alumina plants and device fluctuations. For PVC, the overall supply - demand pattern shows a marginal improvement trend, and it is expected to stop falling and stabilize in September. Attention should be paid to downstream demand performance [12]. Urea Industry - The urea futures price is running weakly, mainly due to the phase mismatch between the continuous increase in supply and weak domestic demand. Although export orders support some enterprises, the export's ability to digest inventory is limited. The market sentiment is restricted by high inventory and weak demand [18]. Polyolefin Industry - The market shows a pattern of "decreasing supply and increasing demand", and the core contradiction is not obvious. For PP, the PDH and external propylene procurement profits are suppressed, and the basis is still weak. For PE, the current maintenance is relatively high, and the short - term supply pressure is small, but attention should be paid to the supply rhythm. Attention should also be paid to downstream restocking before the Double - Festival [21]. Pure Benzene and Styrene Industry - The weekly supply - demand of pure benzene is weak, and the price driving force is weak. In the short term, BZ2603 follows the fluctuations of oil prices and styrene. The weekly supply - demand of styrene has improved, and there is an expectation of further improvement in the future. The low price of styrene has support, but the rebound space is limited due to high port inventory [43]. Polyester Industry - For PX, the supply is increasing to a relatively high level, and the short - term demand has some support, but the mid - term supply - demand is expected to be tight, and the price has support at the low level. However, the cost support is limited, and the rebound space is restricted. For PTA, the supply - demand is expected to be tight in September, but the basis and processing fee repair driving force are limited. For ethylene glycol, the supply - demand pattern is strong in the near term and weak in the long term. For short - fiber, the short - term supply - demand is weak, and it mainly follows the raw material fluctuations. For bottle - chips, the supply increases slightly, and the demand may decline, and the processing fee space is limited [47]. 3.
