Report Industry Investment Rating - The report does not explicitly provide an overall industry investment rating. However, for individual commodities, the ratings are as follows: - Crude oil: Oscillating [1] - Fuel oil: Oscillating [3] - Asphalt: Oscillating [3] - Polyester: Oscillating [3] - Rubber: Oscillating [5] - Methanol: Oscillating, with a bias towards strength [5] - Polyolefins: Oscillating [6] - Polyvinyl chloride (PVC): Oscillating, with a bias towards weakness [6] Report's Core View - The report analyzes the market conditions of various energy and chemical commodities on September 2, 2025. It takes into account factors such as geopolitical situations, supply - demand dynamics, and cost - end fluctuations to provide views on price trends for each commodity. For example, due to geopolitical tensions in the Red Sea and the Russia - Ukraine situation, the oil market's geopolitical pricing may rise again, and oil prices can be considered from a rebound perspective [1]. Summary by Relevant Catalogs Research Views - **Crude oil**: On Monday, Brent's new November contract rose 0.67 dollars to 68.15 dollars per barrel, a 0.99% increase. SC2510 closed at 488.9 yuan per barrel, up 5.3 yuan or 1.10%. Geopolitical factors such as the possible suspension of diplomatic efforts and the Red Sea missile incident may lead to a rebound in oil prices [1]. - **Fuel oil**: The main contract of high - sulfur fuel oil (FU2510) rose 0.25% to 2832 yuan per ton, while the main contract of low - sulfur fuel oil (LU2511) fell 0.49% to 3474 yuan per ton. The expected reduction in Western arbitrage cargo inflows in September may boost the fundamentals of low - sulfur fuel oil, but overall demand for both high - and low - sulfur fuel oil lacks significant highlights [3]. - **Asphalt**: The main contract of asphalt (BU2510) rose 1% to 3540 yuan per ton. In September, the demand for road construction in the north increases, but the rise in supply in North China and Northeast China may limit price increases. Overall, the supply - demand contradiction is expected to ease, and prices may rise further [3]. - **Polyester**: TA601 closed at 4772 yuan per ton, down 0.25%. EG2601 closed at 4427 yuan per ton, down 0.87%. PX supply is high, and downstream TA maintenance volume is increasing. TA prices are expected to be supported and oscillate. Ethylene glycol prices are expected to oscillate with a bias towards strength due to supply reduction and demand increase [3][4]. - **Rubber**: The main contract of natural rubber (RU2601) remained unchanged at 15860 yuan per ton, while the main contract of 20 - number rubber (NR) fell 15 yuan to 12680 yuan per ton. Supply weather is favorable, raw material prices fluctuate slightly, demand is stable domestically and weak overseas, and inventory is slightly decreasing. Rubber prices are expected to oscillate [5]. - **Methanol**: Due to the recovery of profits, MTO devices may resume production. In September, supply growth is limited, demand is expected to pick up, and inventory is expected to peak. Methanol prices are expected to enter a phased bottom area [5]. - **Polyolefins**: In September, supply and demand are both strong, inventory is gradually transferred from society to downstream, and fundamentals have few contradictions. Polyolefin prices are expected to continue to fluctuate narrowly [6]. - **Polyvinyl chloride (PVC)**: Real - estate construction recovery is weak, and demand for PVC downstream products is limited. With India's higher anti - dumping duties, exports are expected to decline. PVC prices in September are expected to oscillate with a bias towards weakness [6]. Daily Data Monitoring - The report provides data on the basis of various energy and chemical products, including spot prices, futures prices, basis, basis rates, and their changes and historical quantiles [7]. Market News - Trump is considering suspending diplomatic efforts until more flexibility is shown.

Report Summary 1. Report Industry Investment Rating No information provided. 2. Core Viewpoints - Ethylene glycol's recent fundamental drivers are limited. It was relatively resistant to price drops due to low inventory, but with the cooling of the chemical sector sentiment and lack of policy support, it has seen a compensatory decline. However, considering its low inventory, low valuation, and inelastic supply, it is expected to remain in an upward - biased trend. In the short - term, it oscillates in the 4350 - 4550 range, mainly following the cost side and commodity sentiment. It is recommended to buy on dips within the range. In the long - term, the performance of the downstream polyester peak season needs to be observed, and long positions can be combined with selling out - of - the - money near - month call options for covered operations [3]. 3. Summary by Relevant Catalogs 3.1 Polyester Price Range Forecast - Ethylene glycol price range (monthly) is 4300 - 4700, with a current 20 - day rolling volatility of 9.09% and a 3 - year historical percentile of 1.4%. - PX price range (monthly) is 6500 - 7400, with a current 20 - day rolling volatility of 11.78% and a 3 - year historical percentile of 17.7%. - PTA price range (monthly) is 4400 - 5300, with a current 20 - day rolling volatility of 9.30% and a 3 - year historical percentile of 4.6%. - Bottle chip price range (monthly) is 5800 - 6500, with a current 20 - day rolling volatility of 7.92% and a 3 - year historical percentile of 0.9% [2]. 3.2 Polyester Hedging Strategy **Inventory Management**: - For high finished - product inventory and concerns about ethylene glycol price drops, sell EG2601 futures with a 25% hedging ratio in the 4500 - 4600 range to lock in profits. - Buy EG2510P4400 put options and sell EG2510C4500 call options with a 50% hedging ratio in the 20 - 30 range to prevent large price drops and reduce capital costs [2]. **Procurement Management**: - For low procurement inventory and the need to lock in procurement costs, buy EG2601 futures with a 50% hedging ratio in the 4350 - 4400 range. - Sell EG2510P4350 put options with a 75% hedging ratio in the 18 - 30 range to collect premiums and lock in the purchase price if the price drops [2]. 3.3利多解读 - This week's planned arrivals are 11.01 tons, relatively low. Next Monday, port inventory is expected to decrease by about 1.5 tons, tightening spot liquidity. - Houthi attacks on Red Sea cruise ships led to an afternoon increase in oil prices, but the cost - side support was limited, and EG rebounded slightly before falling again [5]. 3.4利空解读 - Weaving terminal demand has shown a phased decline, with limited new orders. High temperatures in Jiangsu and Zhejiang have led to a slight decrease in loom operation rates. - Due to poor production efficiency and order intake, bottle chip factories have cancelled production increase plans, limiting polyester's production increase in September [6]. 3.5 Polyester Daily Data - Includes price data (such as Brent crude oil, PX, PTA, etc.), price differences (such as TA1 - 5 month spread, EG1 - 5 month spread), and processing fees (such as gasoline reforming spread, aromatics reforming spread) for different time points (2025 - 09 - 01, 2025 - 08 - 29, 2025 - 08 - 25) and their daily and weekly changes [8][9].

Report Summary 1) Report Industry Investment Rating - There is no information about the industry investment rating in the provided content. 2) Core Viewpoints - PTA: The spread between PX and naphtha has expanded, and the weak benzene price has inhibited the further increase of PX production. The spread between PX and MX has rebounded, the downstream polyester load has remained at around 88%, domestic PTA plants have gradually returned, and domestic PTA production has increased. With the recent improvement in sales and inventory reduction, especially the better reduction of filament inventory, profits have been significantly repaired. However, the maintenance expectation of some downstream devices is relatively strong [2]. - Ethylene Glycol (MEG): The planned production cut of South Korean naphtha cracking units has led to a sharp rise in olefin varieties. The price of ethylene glycol has rebounded. The continuous postponement of the maintenance of overseas ethylene glycol plants, especially Saudi Arabian plants, may have a significant impact on the market outlook, which is constantly boosting the price of ethylene glycol. The later arrival volume of ethylene glycol has decreased. Polyester inventory is performing well, and the downstream weaving load has rebounded [2]. 3) Summary by Relevant Catalogs a.

The sales of polyester yarn in Jiangsu and Zhejiang on the 29th were weak, and the sales of direct - spun polyester staple fibers were average [4][5] Trend Intensity - PX trend intensity: 1 - PTA trend intensity: 1 - MEG trend intensity: 0 [5]

1. Report Industry Investment Rating - The investment view is "oscillating" [3] 2. Core View of the Report - The market's supply is increasing, and the overall expectation is bearish, with the market expected to oscillate [3] 3. Summary by Relevant Catalogs PART ONE: Main Views and Strategy Overview - **Supply**: Domestic PTA device supply is gradually recovering, with increased supply from Huizhou, and the PTA basis is weakening. The spread between PX and naphtha is expanding, and the spread between PX and MX is rising [3] - **Demand**: The downstream load of polyester remains at around 88%, and the inventory of polyester factories is optimistic. The bottle - chip device maintenance is also recovering. With the recent improvement in sales and inventory reduction, polyester prices are performing well, especially for filaments. However, FDY production cuts are imminent [3] - **Inventory**: PTA port inventory is declining, entering a destocking cycle, with a reduction of 20,000 tons this week [3] - **Basis**: The PTA basis is rapidly weakening, and the liquidity in the PTA market is becoming looser due to the return of South China devices [3] - **Profit**: The spread between PX and naphtha is at $260, and the spread between PX and MX is expanding. The PTA processing fee remains at around 200 yuan and is contracting [3] - **Valuation**: PTA prices are at a moderately low level. As the reforming devices gradually recover, the supply of aromatics is increasing [3] - **Macro - policy**: Positive influence from relevant political meetings [3] - **Investment view**: Market is expected to oscillate due to bearish market expectations and increased supply [3] - **Trading strategy**: For unilateral trading, it is recommended to wait and see, and pay attention to geopolitical risks [3] PART TWO: Overview of Oil Product Fundamentals - **Oil market news**: On August 29, the Political Bureau of the CPC Central Committee held a meeting.

North American and Asian naphtha prices are weakening, and the spread between naphtha and Brent crude oil is narrowing. The premium between Asian 97RON premium gasoline and regular gasoline continues to rise, and the lower naphtha price has increased the profit margin of reforming devices [48] - **Aromatics profit**: The profit from selective disproportionation is declining. The spread between PX and mixed xylene has increased to $127/ton, still generating positive returns. The consumption in the gasoline blending industry remains low, while the output of traditional derivative industries remains stable [54] - **Reforming device**: Although the supply of naphtha has eased, the demand is expected to decline due to planned maintenance in the third quarter. The demand for PX remains healthy, and the spread between PX and naphtha has risen to $265. After the completion of planned maintenance, the supply of PX has increased [61] - **Korean market**: There are expectations of production cuts in Korean naphtha cracking devices, and the market is in a period of sentiment fermentation and waiting for news verification [70] PART FOUR: Overview of Polyester Fundamentals - **Ethylene glycol**: There are rumors of major reforms in the domestic petrochemical and refining industries. Korean naphtha cracking devices plan to cut production, causing a significant increase in olefin varieties. Overseas ethylene glycol device maintenance has been postponed, and the supply is expected to shrink, with a decrease in expected arrivals [82] - **Gasoline**: Gasoline profits are recovering, and the load of major refineries is rising [84] - **Polyester**: The supply side of bottle - chips is gradually recovering. Raw material prices are stable, and terminal demand is optimistic [90][100]

Report Summary 1) Report Industry Investment Rating No information provided. 2) Core View of the Report - PTA market: The PTA market is bearish due to weak crude oil prices and news of possible production cuts in downstream polyester bottle chips. Domestic PTA production has slightly decreased due to concentrated breakdowns and maintenance of PTA plants. The spread between PX and naphtha has widened, and the weak benzene price has restricted the further increase of PX production. The spread between PX and MX has recovered, and the downstream polyester load has remained at around 88%. The polyester price has shown a positive trend, especially the inventory of filament has been well reduced, and the production and sales have been continuously optimistic with obvious profit repair. [2] - MEG market: There are rumors that China is planning a major reform of its petrochemical and refining industries, aiming to gradually eliminate small - scale and outdated facilities and shift investment to advanced materials. South Korean naphtha cracking units are planning to cut production, and olefin varieties have risen significantly. The price of ethylene glycol has recovered, and the continuous postponement of overseas ethylene glycol plant maintenance, especially in Saudi Arabia, may have a significant impact on the market outlook. The future arrival volume of ethylene glycol has decreased, the polyester inventory is in good condition, and the downstream weaving load has increased.

Report Industry Investment Ratings No relevant content provided. Core Views of the Reports Crude Oil - Overnight oil prices oscillated weakly due to concerns about global crude oil supply surplus and seasonal demand decline. OPEC+ relaxing production cuts and non - OPEC+ countries increasing production led to higher supply expectations. While refinery profits are good currently, the approaching end of the US summer driving season reduces gasoline demand expectations. Geopolitical factors offer some support but the overall market sentiment is bearish, with a high probability of short - term weak oscillation. It is recommended to wait and see on the single - side and look for opportunities to widen spreads on the option side after volatility increases [1]. Polyester Industry - PX: Supply is increasing as检修 devices restart, and downstream PTA has many unplanned shutdowns due to low processing fees. Although the "Golden September and Silver October" demand expectation exists, terminal load declined this week, and the demand support is limited. PX11 should focus on the support around 6800, and the strategy of widening the PX - SC spread should exit at high levels [43]. - PTA: In August - September, supply - demand situation has improved compared to expectations due to more unplanned shutdowns. However, terminal load declined this week, and demand support is limited. TA should focus on the support around 4750 and adopt a rolling reverse spread strategy for TA1 - 5 [43]. - Ethylene Glycol: Domestic supply is increasing as devices resume production, and port inventory is at a low level. With the approaching of the demand peak season, it is expected to oscillate strongly in the short - term. Sellers of the short - put option EG2601 - P - 4350 can hold [43]. - Short - fiber: Supply load remains high, demand is uncertain, and it mainly follows raw material fluctuations. The single - side strategy is the same as PTA, and the processing fee on the disk oscillates between 800 - 1100 with limited upward and downward drivers [43]. - Bottle chips: In August, it is the peak consumption season, and inventory is slowly decreasing. The processing fee has support at the bottom, but it is suppressed by the short - term strengthening of the cost side. The PR single - side strategy is the same as PTA, and the main - contract processing fee on the disk is expected to fluctuate between 350 - 500 yuan/ton [43]. Methanol - Port inventory is increasing significantly, the basis is weak, and imports in September remain high. The supply side has high domestic and rising overseas non - Iranian production. The demand side is weak due to the off - season, but there is an expectation of MTO device restart in September. Future attention should be paid to the inventory inflection point [72][74]. Urea - The rebound of the urea futures is driven by short - term supply contraction due to more device shutdowns for maintenance. Although daily production is still higher than last year, the expected production reduction supports the market. Downstream restocking also strengthens the supply - contraction expectation. However, the market is still in a state of inventory accumulation, and the rebound strength may be limited. Future attention should be paid to device restart progress, port collection, and industrial demand in North China before the parade [85]. Polyolefins - PP: Devices scheduled for restart next week will increase production. The price center is moving down, and the weighted profit is compressed. PP achieves inventory reduction with both supply and demand increasing. - PE: High - level maintenance will continue until September. It shows a stable - to - downward trend. Supply decreases while demand increases, with upstream inventory reduction and mid - stream inventory accumulation. Before mid - September, the overall supply pressure is not large, and the LP01 spread should be held [88]. Chlor - Alkali - Caustic Soda: The futures price is slightly falling, and the previous high - level resistance is obvious. Although the spot market was strong before, with good demand from Shandong's downstream alumina plants and inventory reduction, the supply is expected to increase as some plants resume production. The demand is growing, but the short - term futures pressure may be transmitted to the spot market, and short - selling can be considered [91]. - PVC: The futures price is weakening, and the spot price is also decreasing. Supply is expected to increase as new production capacity is put into use and maintenance decreases. Demand from downstream products is weak, and export pressure increases due to the Indonesian anti - dumping tax. Previous short positions can be held [91]. Pure Benzene - Styrene - Pure Benzene: There is an expectation of supply - demand improvement in the third quarter, but as previous maintenance devices resume and there will be a concentrated arrival of pure benzene at the terminal in the second half of the month, the fundamental advantage is weakening. It oscillates weakly, and BZ2603 should follow the fluctuations of oil prices and styrene [94]. - Styrene: Downstream 3S load declined slightly this week. The industry is in a loss, supply is high, and port inventory is high, so the short - term drive is weak. However, there are more maintenance plans in September - October, and export expectations increase, so the supply - demand situation may improve. EB10 short positions should be closed at low levels, and short - selling on rebounds is recommended [94].
