Report Industry Investment Rating No relevant content provided. Core Viewpoints - Cost - end: Overnight crude oil prices dropped significantly and continued to decline during Asian trading hours. The 50% tariff imposed by the US on India led to a bearish outlook on crude oil demand, and API inventory data showed an unexpected inventory build in the US, pressuring oil prices. For PX, China's PX load is gradually recovering, and the PX balance sheet has shifted from de - stocking to a loose balance. Although the near - month PX floating price has weakened, PXN has support due to low inventory and new PTA device demand. For TA, PTA maintenance has increased, improving supply - demand, and the September balance sheet will shift from a loose balance to significant de - stocking. The reduction of September contracts by Hengli may cause supply - demand tension in South China [2]. - Demand: The polyester operating rate is 90.0% (up 0.6% month - on - month), showing signs of recovery. Export shipments and domestic sales stocking are increasing. The load of weaving and texturing is on the rise, with the peak expected in September. Currently, the inventory of filament factories has decreased significantly, and profitability is improving. The bottle - chip market has slow de - stocking, and the load is expected to recover in September. For PF, the production profit is 107 yuan/ton (up 35 yuan/ton month - on - month), and the average load has increased to 91.9%. The downstream load is rising, and inventory is being depleted. For PR, the spot processing fee is 297 yuan/ton (up 29 yuan/ton month - on - month), and major factories will maintain production cuts in August, with the load expected to remain stable in the short term [3]. - Strategy: Unilateral: PX/PTA/PF/PR are rated neutral. Continue to monitor the PX devices of Shenghong and Zhejiang Petrochemical. For PX, the concentrated restart of PX devices in August and increased PTA maintenance have weakened the fundamentals, but low inventory supports PXN. For TA, the improvement in supply - demand due to PTA maintenance in August and the shift to de - stocking in September, along with potential supply - demand tension in South China, require attention to the return of maintenance devices. For PF, demand has slightly improved, and inventory is being depleted, but the willingness to chase rising raw material prices is low. For PR, major factories have extended maintenance plans, and the spot processing fee is expected to return to range - bound trading after recovery. Cross - variety: Go long on PF processing fees at low prices: PF2511 - 0.855PTA2601 - 0.335MEG2601. Cross - period: No relevant strategies [4].

Report Summary 1. Report Industry Investment Rating No specific industry investment rating is provided in the report. 2. Core Views - PX: Affected by the weakening of oil prices, the PX price has dropped rapidly, but it remains in a tight - balance pattern with limited downside space. Although this week's PX trend was weaker than expected due to high domestic supply and unconfirmed maintenance plans, there is support from potential oil price rebounds and polyester sales volume at low prices. It is recommended to continue to focus on the positive spread position of monthly differentials and go long on PX and short on EB [6]. - PTA: Go long on PTA and short on MEG. This week's PTA trend was weaker than expected. Polyester bottle - chip factories will continue to cut production in September, and the PTA spot basis has weakened. However, PTA supply will be in a tight - balance or even a slight de - stocking situation in September, and the unilateral price is not considered to be in a trend - like decline [7]. - MEG: Do a 9 - 1 positive spread. There is significant pressure above 4600 for the 01 contract, and hedging is recommended at high prices. With low port arrivals in the past two weeks, port inventories have decreased. The basis is strong, and there is an economic incentive to take delivery for the 09 contract. Attention should be paid to the proportion of warehouse - receipt holdings and the 9 - 1 positive spread. There will be new production capacity from Yulong Petrochemical in October, so the 01 contract still faces supply - increase pressure, and it is advisable to focus on the 1 - 5 reverse spread [7][8]. 3. Summary by Related Catalogs Market Dynamics - PX: The price of naphtha rose at the end of the session. On the 28th, the PX price dropped. The Asian PX price fell on August 28 after more than a week of increase, due to the pressure of weakening crude - oil futures. The polyester industry provided little support for the PX price, with the downstream factory operating rate at about 89.9% this week, slightly lower than the previous week. There were bids and offers for October and November deliveries on the 28th, but no transactions were completed [3][4]. - PTA: In the Chinese mainland, Dushan Energy's 2.5 - million - ton plant was under maintenance, Sanfangxiang's 1.2 - million - ton plant was shut down, and the second line of its 3.2 - million - ton new plant was put into production with increased load. As of Thursday, the PTA load was 70.4%, and the calculated operating rate was around 76.1% [5]. - MEG: As of August 28, the overall operating load of ethylene glycol in the Chinese mainland was 75.13% (a 1.97% increase from the previous period), and the operating load of ethylene glycol produced by the oxalic - acid catalytic hydrogenation method (syngas) was 77.74% (a 3.51% decrease from the previous period) [5]. - Polyester: This week, the operating load of large - scale domestic polyester industrial - yarn manufacturers remained basically stable, with individual slight adjustments. As of now, the overall theoretical operating load of domestic polyester industrial yarn is about 72%. There were both maintenance and start - up of polyester plants this week, and the overall polyester load was slightly adjusted locally. As of Thursday, the polyester load in the Chinese mainland was around 89.9%. A 180,000 - ton polyester plant in Changshu was shut down temporarily due to an accident, and the restart time is uncertain. On the 28th, the sales of direct - spun polyester staple fiber were weak, with an average sales - to - production ratio of 44%. The sales - to - production ratio of polyester yarn in Jiangsu and Zhejiang was locally increased, with an average of about 50% - 60% [5].

Report Industry Investment Rating - No relevant information provided Core View - Owing to concerns about sanctions on Russia and increased demand from India, oil prices are rebounding. The domestic PX inventory is at a historical low, offering strong support. Whether PX profitability can continue to rise depends on unforeseen factors. As the downstream demand peak season approaches, polyester production is gradually increasing, and attention should be paid to when positive feedback will occur. PTA has sufficient spot supply, weak downstream polyester sales, and limited upward momentum. The current PTA processing fee is in a low - range, and price increases require market sentiment and new device production expectations. Polyester bottle - chip supply is abundant, and downstream purchasing is weak. The pricing logic of PX, PTA, and PR is cost - driven, and all are expected to fluctuate [2] Summary by Directory Price Information - **Upstream**: On August 26, 2025, WTI crude oil futures settlement price was $63.25 per barrel, down 2.39%; Brent crude oil was $67.22 per barrel, down 2.30%.

International oil prices ended a four - day increase and closed lower. PX, PTA, and PR are all expected to fluctuate [2]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The PTA price is expected to fluctuate weakly due to weak cost and cautious demand expectations. The supply of PX and PTA may increase due to high - device operation rates and new production capacities, while the demand lacks strong support, and inventory may accumulate, putting downward pressure on prices. However, seasonal changes in demand and device changes need to be monitored [1][38]. 3. Summary by Related Catalogs 3.1 Daily Market Summary 3.1.1 PTA & PX - On August 19, the PX主力contract closed at 6,774.0 yuan/ton, up 0.21% from the previous trading day, with a basis of - 165.0 yuan/ton. The PTA主力contract closed at 4,734.0 yuan/ton, down 0.25% from the previous trading day, with a basis of - 64.0 yuan/ton [2]. - The cost - end: On August 19, the Brent crude oil主力contract closed at 66.46 US dollars/barrel, and WTI at 62.58 US dollars/barrel. The demand - end: On August 19, the total transaction volume of the Light Textile City was 487.0 million meters, and the 15 - day average transaction was 485.47 million meters [2]. - Supply side: The operation rates of PX and PTA devices remain high, and with the gradual implementation of new production capacities, the pressure of increased industry supply may continue to be released. The cost - end drive of PX is weak under the background of low - level fluctuations in crude oil prices, and the processing fees of PTA are suppressed by over - capacity, and the willingness of factories to increase production may further exacerbate the supply - loosening situation [2]. - Demand side: The transactions in the Light Textile City maintain a weak and stable pattern. Although the downstream polyester operation rate has not weakened significantly, the fabric orders lack substantial improvement. The traditional textile peak season is approaching, but the demand has not shown a continuous improvement, and the terminal negative feedback pressure continues to be transmitted upstream, making it difficult for the PTA demand side to form effective support [2]. - Inventory side: The PTA factory inventory is restricted by the weak basis structure, and the social inventory continues to accumulate. Currently, there are not many active production - reduction actions by factories, and there is still pressure on the price ceiling [3]. 3.1.2 Polyester - On August 19, the short - fiber主力contract closed at 6,432.0 yuan/ton, down 0.46% from the previous trading day. The spot price in the East China market was 6,500.0 yuan/ton, up 20.0 yuan/ton from the previous trading day, with a basis of 68.0 yuan/ton [4]. - Supply side: The PX price has recently shown high - level fluctuations (ranging from 6,614 to 6,832 yuan/ton from August 11 - 19), but the PTA price has risen steadily (up 1.4% to 4,746 yuan/ton during the same period), indicating that the cost - end support is weakening but the downstream acceptance is good [4]. - Demand side: The 15 - day moving average transaction volume of the Light Textile City has continuously rebounded from 479 million meters to 485 million meters, reflecting the gradual recovery of terminal textile demand [4]. - Inventory side: There is a structural differentiation in inventory. The inventory days of polyester staple fiber (7.25 days) are significantly higher than the five - year average (4.96 days), while the inventory of polyester filament POY (16.1 days) is lower than the average (20.4 days), and the inventory of FDY/DTY is basically the same as the historical average. The high - inventory pressure of short - fiber may restrict the overall increase, and continue to pay attention to polyester production - reduction information [4]. 3.2 Industrial Chain Price Monitoring - PX futures: The主力contract price on August 19 was 6,774 yuan/ton, up 0.21% from the previous day; the成交volume increased by 68.14%, and the持仓volume increased by 6.83%. PX spot: The CFR price at the main Chinese port remained unchanged at 833.33 US dollars/ton, and the FOB price in South Korea increased by 0.25% [5]. - PTA futures: The主力contract price on August 19 was 4,734 yuan/ton, down 0.25% from the previous day; the成交volume decreased by 16.25%, and the持仓volume decreased by 2.41%. PTA spot: The CFR price at the main Chinese port remained unchanged at 623 US dollars/ton [5]. - Short - fiber futures: The主力contract price on August 19 was 6,432 yuan/ton, down 0.46% from the previous day; the成交volume increased by 7.48%, and the持仓volume decreased by 0.53%. Short - fiber spot: The mainstream price in the East China market increased by 0.08% [5]. - Other prices: The prices of Brent crude oil, US crude oil, CFR Japanese naphtha, ethylene glycol, polyester chips, polyester bottle flakes, polyester POY, polyester DTY, and polyester FDY remained unchanged or changed slightly on August 19 compared with the previous day [5]. - Processing spreads: The processing spreads of naphtha decreased by 1.09%, and the processing spreads of PTA decreased by 1.57%, while the processing spreads of other products remained unchanged [6]. - Light Textile City transaction volume: On August 19, the total transaction volume was 487 million meters, a decrease of 4.32% compared with the previous day, with the long - fiber fabric volume decreasing by 2.72% and the short - fiber fabric volume decreasing by 9.71% [6]. - Industrial chain load rates: The load rates of PTA factories, polyester factories, and Jiangsu - Zhejiang looms remained unchanged on August 19 [6]. - Inventory days: From August 7 to August 14, the inventory days of polyester staple fiber, POY, FDY, and DTY all decreased [6]. 3.3 Industry Dynamics and Interpretation 3.3.1 Macroeconomic Dynamics - On August 19, due to the UK inflation data being higher than expected, traders reduced their bets on the Bank of England's interest - rate cuts, believing that there would be no further cuts this year [7]. - On August 18, Fed's Daly said to wait for more data, and the number of interest - rate cuts may be less or more. It is still a good prediction to cut interest rates twice this year; Goolsbee said that the latest PPI and CPI inflation data were disturbing. If signs show that inflation is not in a spiral in September or later in the fall, interest rates can be cut. The market reduced its bets on interest - rate cuts but still expected a cut in September and another cut in 2025 [7]. - On August 18, Hong Kong's Financial Secretary Paul Chan said that the plan for Hong Kong to develop an international gold trading center would be announced within the year [7]. 3.3.2 Supply - Demand (Demand) - On August 19, the total transaction volume of the Light Textile City was 487.0 million meters, a month - on - month decrease of 4.32%, with the long - fiber fabric transaction volume at 393.0 million meters and the short - fiber fabric transaction volume at 93.0 million meters [8]. 3.4 Industrial Chain Data Charts The report provides multiple data charts, including PX and PTA主力futures and basis, PX and PTA spot prices, PX capacity utilization, PTA futures monthly spreads, PTA processing profits, industrial chain load rates, polyester short - fiber and long - fiber sales situations, Light Textile City transaction volume moving average, and polyester product inventory days [9][11][13].

Core Viewpoint - The PTA industry is facing significant production losses due to new capacity coming online, while profits are concentrated in the upstream PX segment, with no planned maintenance for PTA facilities in the short term [1][6]. Group 1: PTA Industry Analysis - As of August 14, the average processing fee for PTA in August is 195 yuan/ton, down 19% from July, marking a 22-month low [1]. - The theoretical production loss for PTA companies is estimated at 305 yuan/ton, based on a processing cost line of 500 yuan/ton [1]. - The main reason for PTA's production losses is the new capacity coming online and the continued supply-demand mismatch in PX, which remains relatively strong [1][3]. Group 2: Supply and Demand Dynamics - The polyester industry chain's profits are currently concentrated in the upstream PX and downstream polyester filament POY segments [3]. - The theoretical profit for PX is 381 yuan/ton, up 41 yuan/ton from July, while polyester filament POY has turned profitable with a theoretical profit of 29 yuan/ton [3]. - Despite the severe losses faced by PTA, the supply pressure is expected to increase with the upcoming new PTA capacities, which may not be offset by any planned maintenance [3][4]. Group 3: Future Outlook - The PX supply-demand imbalance is expected to continue, with new PTA capacities potentially increasing PX demand by 34.7 thousand tons/month if they stabilize by October [4]. - Polyester inventory levels are relatively low, with POY at 17 days, FDY at 25 days, short fibers at 12 days, and polyester chips at 7.5 days as of August 14 [4]. - The anticipated demand recovery during the "Golden September and Silver October" period may support profit recovery for polyester products, while PTA continues to face supply pressure from new capacities [6].

Group 1: Report Summary - The report is a polyester data weekly report released on August 17, 2025, by Guotai Junan Futures, focusing on PX, PTA, and MEG [1][2] Group 2: PX Analysis Core View - PX supply increases while demand decreases, leading to a decline in processing fees. However, the gradual improvement in terminal demand may limit the downside space for the single - side price [3] Supply - China's PX operating rate is 84.3% (+2.3%), and Asia's overall operating rate is 74% (+0.4%). Domestic supply is abundant with some plants restarting or increasing loads. Overseas, there are both restarts and maintenance, with little impact on production [3][51] Demand - This week, the PTA operating rate is 76.0% (-0.2%), with some plants shutting down and others restarting [3][4] Valuation - The PX - naphtha spread is 253 US dollars/ton (-8), and the PX - MX spread is 117 US dollars/ton (-4) [3] Strategy - For single - side trading, reduce short positions; for inter - period trading, conduct 1 - 5 reverse spreads; for inter - variety trading, go long on PX and short on PTA, long on PX and short on EB, long on naphtha and short on PX in the 01 contract [3] Group 3: PTA Analysis Core View - Reduce short positions on dips and hold the 9 - 1 reverse spread [4] Supply - The PTA operating rate is 76.0% (-0.2%), with some plants shutting down and others restarting [4] Demand - The polyester operating rate is revised up to 89.4% (+0.6%). The recovery of the bottle - chip factory's operating rate is postponed to September. The downstream operating rate of polyester is slowly rising, and the speed of recovery will accelerate in September [4] Valuation - The PTA spot processing fee is 207 yuan/ton (+20), the 01 contract processing fee is 344 yuan/ton (+13) with a downward trend, and the 09 contract processing fee is 252 yuan/ton (-26). The basis is maintained at - 15 yuan/ton [4] Strategy - For single - side trading, reduce and exit short positions; for inter - period trading, hold the 9 - 1 month - spread reverse spread; for inter - variety trading, hold long PX and short PTA, long MEG and short PTA in the 01 contract [4] Group 4: MEG Analysis Core View - The single - side trend is weakly oscillating, and hold the mid - term long MEG and short PTA position [5] Supply - There were short - term shutdowns and restarts of some plants.

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - PTA lacks new drivers and is expected to maintain a volatile pattern in the short term due to limited changes in domestic installations, a slight warming in the terminal atmosphere, and a lack of significant contradictions between supply and demand [1][5]. - MEG is in a de - stocking cycle, with limited downside space. The supply - demand structure is relatively optimistic, and it is expected to undergo narrow - range consolidation in the short term [1][5]. 3. Summary by Directory 3.1. Upstream Analysis of the Industrial Chain - **Market Review**: OPEC+ production increase brought bearish pressure, geopolitical tensions eased, and the global economy remained weak, leading to a decline in international crude oil prices. PX prices fell slightly due to cost reduction and poor terminal support. As of August 8, the Asian PX closing price was $831.67 per ton CFR China, down $14 per ton from August 1 [17]. - **PX Device Status**: There were no device changes during the week. The average weekly capacity utilization rate of domestic PX was 82.35%, unchanged from the previous week; the average weekly capacity utilization rate of Asian PX was 71.95%, a decrease of 0.03% [20]. - **Supply - Demand and Price Difference**: As of August 8, the PX - naphtha price difference was $261.2 per ton, up $19.38 per ton from August 1. The downstream market was in the off - season, and the terminal market support was poor, but with the commissioning of new PTA devices, there was an expected increase in demand, resulting in narrow - range fluctuations in the PX - naphtha price difference [23]. 3.2. PTA Fundamental Analysis - **Market Review**: This week, some installations in East China were shut down for maintenance or reduced production due to efficiency issues, leading to a significant reduction in overall supply. The terminal was in the traditional off - season, and demand changes were minimal. The supply - demand balance sheet shifted to de - stocking. However, due to the impact of OPEC production increase on crude oil prices, the PTA price center oscillated downward. As of August 8, the PTA spot price was 4,670 yuan per ton, and the spot basis was 2509 - 17 [26]. - **Device Utilization**: The average weekly capacity utilization rate of PTA dropped to 75.92%, a decrease of 3.75% compared to the previous week. Multiple installations in East China were shut down or under maintenance, and some enterprises reduced production due to efficiency issues, resulting in a significant reduction in domestic production this period. In August, with the mass production of Hailun Petrochemical and maintenance plans of Tongkun, Yisheng, and Hengli, it is expected that the capacity utilization rate of domestic PTA devices may drop to around 74% [29]. - **Processing Fees**: The processing fees of PTA decreased significantly this week due to increased long - term supply pressure, active sales by major producers, and tight supply of raw material PX. With an expected increase in supply and average demand, the supply - demand balance sheet shows narrow - range de - stocking. However, due to efficiency issues, some enterprises reduced production. PTA is expected to rebound at a low valuation, and the processing fees may be slightly repaired [30]. - **Supply - Demand Balance in August**: In August, with the mass production of new PTA devices and multiple planned maintenance installations, and considering the potential reduction in polyester load due to continuous losses, the supply - demand is expected to be in a wide - range balance [33]. 3.3. MEG Fundamental Analysis - **Price Movement**: At the beginning of the week, influenced by crude oil and macro factors, the price of ethylene glycol declined. However, the de - stocking of supply and demand provided positive support, limiting the market decline. When the price dropped to around 4,450 yuan, it stabilized and rebounded. As of August 8, the closing price of Zhangjiagang ethylene glycol was 4,456 yuan per ton, and the delivered price in the South China market was 4,480 yuan per ton [39]. - **Device Utilization**: The overall capacity utilization rate of ethylene glycol in China was 61.42%, a 0.75% increase compared to the previous week. Among them, the capacity utilization rate of integrated devices was 58.28%, a decrease of 0.39%, and the capacity utilization rate of coal - based ethylene glycol was 66.47%, an increase of 2.59%. In August, for domestic production, some existing devices will restart and undergo maintenance simultaneously, and the restart of a major factory in Jiangsu is postponed, resulting in a slight increase in overall production [42]. - **Port Inventory**: As of August 7, the total inventory of MEG ports in the main ports of East China was 48.57 tons, an increase of 2.22 tons compared to August 4 and an increase of 5.85 tons compared to July 31. As of August 13, 2025, the total expected arrival volume of domestic ethylene glycol in East China is 10.17 tons, including 3.57 tons in Zhangjiagang, 5.9 tons in Taicang, and 0.7 tons in Jiangyin [45]. - **Processing Profits**: The supply - demand de - stocking logic still exists. After a decline this week, ethylene glycol rebounded. The prices of the raw material market fluctuated, resulting in both increases and decreases in the sample profits of each ethylene glycol process. As of August 8, the profit of naphtha - based ethylene glycol was - $98.67 per ton, a decrease of $14.29 per ton compared to the previous week; the profit of coal - based ethylene glycol was 21.33 yuan per ton, a decrease of 93.53 yuan compared to the previous week [48]. 3.4. Downstream Demand Analysis of the Industrial Chain - **Polyester Capacity Utilization**: The average weekly capacity utilization rate of polyester was 86.21%, a 0.39% increase compared to the previous week. After the commissioning of Youshun's new device, the load gradually increased, and Huaya's device restarted after a short - term shutdown, resulting in a slight increase in domestic polyester supply. It is expected that the domestic polyester production will increase slightly next week [51]. - **Terminal Impact on Polyester**: In July, polyester factories were affected by terminal restrictions and poor profit levels, resulting in a decline in the polyester operating rate, but the decline was limited. In August, with both maintenance and restart plans and new device commissioning, but considering the poor demand outlook, it is expected that the monthly polyester production will decline slightly [52]. - **Differentiation in Polyester Product Capacity Utilization**: This week, the average weekly capacity utilization rate of polyester filament was 90.66%, a 0.85% decrease compared to the previous period. The average capacity utilization rate of polyester staple fiber was 86.49%, a 1.81% increase compared to the previous week. The capacity utilization rate of fiber - grade polyester chips was 76.36%, a 1.85% increase compared to the previous week [57]. - **Polyester Product Inventory**: Due to pre - replenishment, the factory sales data was average this week, and the finished product inventory increased slightly [58]. - **Polyester Product Cash Flow**: The polymerization cost decreased slightly. Polyester products were mostly in a wait - and - see state this week, with limited downward space and partial cash - flow repair [62]. - **Textile Industry Situation**: As of August 7, the comprehensive operating rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 55.75%, a 0.24% increase compared to the previous data. The average number of terminal weaving order days was 6.84 days, a decrease of 0.49 days compared to the previous week. In August, the inquiry atmosphere for domestic autumn and winter fabrics improved slightly, but due to high inventory in fabric production factories and sufficient supplies from middlemen, there was no significant improvement in domestic and foreign orders, and factories had little intention to increase production [67]. 3.5. Summary of the Polyester Industrial Chain Fundamentals - **Cost End**: OPEC+ production increase brought bearish pressure, geopolitical tensions eased, and the global economy remained weak, leading to a decline in international crude oil prices. PX prices fell slightly due to cost reduction and poor terminal support [68]. - **Supply End**: The average weekly capacity utilization rate of PTA dropped to 75.92%, a 3.75% decrease compared to the previous week, and domestic production decreased significantly. The total capacity utilization rate of domestic ethylene glycol was 61.42%, a 0.75% increase compared to the previous week [69]. - **Demand End**: The average weekly capacity utilization rate of polyester was 86.21%, a 0.39% increase compared to the previous week. The comprehensive operating rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 55.75%, a 0.24% increase compared to the previous data. The average number of terminal weaving order days was 6.84 days, a decrease of 0.49 days compared to the previous week. The inquiry atmosphere for domestic autumn and winter fabrics improved slightly, but there was no significant improvement in orders, and factories had little intention to increase production [69]. - **Inventory**: PTA was in a de - stocking state this week. As of August 7, the total inventory of MEG ports in the main ports of East China was 48.57 tons, an increase compared to the previous period [69].
