Affected by the rumor of new device early launch, it became a concentrated short allocation and weakened. Although the pattern remains in a stocking trend, it is expected to have large upward elasticity when bullish drivers appear. Currently, it oscillates in the range of 4250 - 4500, and it is recommended to go long on dips or sell the 10 - contract 4250 put [3] Group 5: Bullish Factors - This week's planned arrival is 11.01 tons, relatively small. Next Monday, port inventory is expected to decrease by about 1.5 tons, and spot liquidity is expected to tighten further [5] - Due to the Houthi armed attack on a cruise ship in the northern Red Sea, oil prices rose in the afternoon, but the cost - end support was limited, and EG rebounded slightly and then fell again [5] Group 6: Bearish Factors - There is a market rumor that the new 800,000 - ton ethylene glycol capacity of Yulong will be launched in September. If true, it will run at a low load in September and add an additional 50,000 - 60,000 tons in October [6] - The terminal demand of weaving has declined recently, with limited new orders. Coupled with the continuous high temperature in Jiangsu and Zhejiang, the loom operation rate has decreased slightly [6] - Due to poor production efficiency and order - receiving situation, bottle chip factories have cancelled their production increase plans, and the polyester operation rate in September is highly restricted [6] Group 7: Price and Spread Data - Various prices and spreads of polyester - related products such as Brent crude oil, naphtha, PX, PTA, ethylene glycol, etc., including daily and weekly changes, are presented in the polyester daily report tables [9][10] Group 8: Processing Fee and Profit Data - Processing fees and profits of products such as gasoline reforming spread, aromatics reforming spread, POY, DTY, etc., including daily and weekly changes, are presented in the polyester daily report tables [10]

Report Industry Investment Ratings - Urea: ★★★ - Methanol: ★★★ - Pure Benzene: ★★★ - Styrene: ★★★ - Polypropylene: ★★★ - Plastic: ★★★ - PVC: ★★☆ - Caustic Soda: ★★★ - PX: ★★★ - PTA: ★★★ - Ethylene Glycol: ★★★ - Short Fiber: ★★★ - Soda Ash: ★☆☆ - Bottle Chip: ★★★ - Propylene: ★★★ - Glass: ★★★ [1] Core Viewpoints - The olefins and polyolefins market shows mixed trends with different factors influencing prices. The polyester market is affected by supply - demand dynamics and cost factors. The coal - chemical market has supply and demand changes due to seasonal factors. The chlor - alkali market is facing supply and demand imbalances. The soda - ash and glass market is in a weak situation with different outlooks for the future [2][4][5][6][7] Summary by Directory Olefins - Polyolefins - Olefins futures: The intraday trend of the main contracts of olefins futures is first down then up. Production enterprise inventory pressure is controllable, but downstream product cost pressure rises, limiting the upward space of propylene prices. There is still market rigid demand support [2] - Polyolefins futures: The main contracts of polyolefins futures fluctuate narrowly. The demand of the polyethylene downstream agricultural film industry continues to follow up, but overall orders may decline slightly. The supply pressure of polypropylene increases, and the weak fundamentals drag down the market [2] Pure Benzene - Benzene: The price of benzene continues to be weak. Domestic supply increases, demand is weak, and the port inventory accumulates slightly. There is an expectation of supply - demand improvement in the third quarter, but the real - time demand is weak [3] - Styrene: The main contract of styrene futures closes down in a volatile manner. Crude oil and pure benzene cannot provide effective support. Demand is weak and stable, supply is high, and port inventory accumulates significantly [3] Polyester - PX: The price of PX fluctuates with support at the lower integer level. The supply - demand expectation improves, but the real - time improvement is limited, and it is in a range - bound oscillation [4] - PTA: It runs below 4800 yuan/ton. Terminal weaving orders increase, but the real - time improvement is limited, and it is in a range - bound oscillation [4] - Ethylene Glycol: It falls back after hitting resistance at the 4500 yuan/ton level. The domestic load continues to increase, and it is expected to maintain range - bound oscillation [4] - Short Fiber: The supply and demand are stable. The price mainly fluctuates with the cost. If the demand improvement is realized in the medium - term, it can be considered for long - position allocation [4] - Bottle Chip: The industry has over - capacity, and the processing margin runs at a low level [4] Coal - Chemical - Methanol: The intraday methanol market is first weak then strong. The supply of inland methanol increases, traditional downstream average start - up declines, and inventory accumulates. But there is an expectation of a stronger market due to downstream device economic repair and pre - holiday stocking [5] - Urea: The futures and spot prices of urea continue to oscillate at a low level. Daily production decreases slightly but is still high year - on - year. The inventory of production enterprises increases, and port inventory also increases. Attention should be paid to the market sentiment around the Indian tender opening [5] Chlor - Alkali - PVC: It weakens. The cost support is not obvious, supply pressure is high, downstream procurement is not active, and social inventory accumulates. The futures price may oscillate weakly [6] - Caustic Soda: It performs strongly. There is still an overhaul expectation in East China, and the inventory pressure is small. The price is relatively firm but may face supply pressure in the future and is expected to be in a wide - range oscillation [6] Soda - Ash and Glass - Soda Ash: It continues to decline. The supply is expected to increase, and the inventory in the industrial chain is high. In the long - term, it is in a supply - demand surplus situation, and short - selling at high rebounds is recommended [7] - Glass: The weak situation continues, and the futures price drops sharply. The spot price decline narrows, and the glass factory destocks. The real - time situation is weak, but at a low - valuation level, long - position at the coal cost level can be considered [7]

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.

Report Summary 1. Investment Ratings - PX: Long PX and short EB, 11 - 01 calendar spread long, 1 - 5 calendar spread short [6] - PTA: Unilateral price is expected to be oscillating with an upward bias, focus on long PTA and short PX for the November contract [7] - MEG: Unilateral oscillating market, avoid chasing long positions, overvalued above 4550, long PTA and short MEG [8] 2. Core Views - PX prices fluctuated this week, with the decline faster and larger than expected due to the halt of the positive feedback of terminal fabric price increases. Asian PX operating rate changed little, and domestic supply is expected to increase marginally in September [6] - PTA prices also fluctuated this week, with the decline exceeding expectations because of concerns about the peak - season performance and slow recovery of polyester operating rate. PTA has shifted to a destocking pattern, and its basis and calendar spread are supported [7] - MEG is in a situation of increasing supply and demand, with ports shifting to a stocking pattern. The 09 contract has limited support for the overall price, and the current polyester operating rate expectations are lowered [8] 3. Summary by Related Catalogs Market Data - **Futures Prices**: PX closed at 6878 with a - 0.12% change, PTA at 4784 (-0.17%), MEG at 4466 (0.02%), PF at 6500 (-0.40%), and SC at 485.2 (0.73%) [1] - **Calendar Spreads**: PX9 - 1 closed at - 108, down 156 from the previous day; PTA9 - 1 at - 62 (-6); MEG9 - 1 at - 37 (+4); PF9 - 1 at - 106 (-10); SC9 - 10 at - 8.2 (+0.5) [1] - **Spot Prices**: PX CFR China was 848.67 (unchanged), PTA in East China at 4740 (-35), MEG at 4534 (+9), naphtha MOPJ at 597.38 (+3.5), and Dated Brent at 67.85 (+0.4) [1] - **Spot Processing Margins**: PX - naphtha spread was 254.79 (-9), PTA processing margin at 221.67 (-29.59), staple fiber processing margin at 137.74 (-18.09), bottle - chip processing margin at - 51.65 (+38.94), and MOPJ naphtha - Dubai crude spread at - 6.01 (unchanged) [1] Market Dynamics - PX spot prices remained unchanged as there were no clear bullish or bearish drivers. The bearish sentiment in the crude oil market limited the increase in Asian PX prices due to concerns about potential consumer price inflation related to US tariff policies [1][2] - In the polyester industry, some polyester bottle - chip plants had restarted, shut down, or adjusted production in September. 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. Indian refineries' September imports of Russian oil are expected to increase by 10% - 20% (150,000 - 300,000 barrels per day) compared to August. Ukrainian attacks on Russian refineries have affected up to 17% of its refining capacity [7] - **Gasoline market**: In the peak season, gasoline inventory is decreasing. North American refinery loads are continuously rising. However, as the driving season is about to end, gasoline demand will enter the off - season, and it is difficult to form strong market expectations. The demand for reformate in gasoline blending is still much better than that for chemicals, and the demand for benzene, toluene, and MX at the terminal remains weak [24] PART THREE: Overview of Aromatics Fundamentals - **Aromatics supply**: The supply of PX is expected to recover. 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]
