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].

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Viewpoints of the Report - The PTA market is waiting for the peace - talk information between the US and a European country. International oil prices are weak, and PTA has insufficient cost support. With a weak supply - demand structure, the PTA market declined slightly today. The PTA supply has shrunk, and port inventories have decreased. The spread between PX and naphtha has expanded, but alkyl transfer and TDP profit margins are not optimistic. PTA basis has weakened, and market replenishment willingness has declined [2] - The coal price has rebounded, driving up the ethylene glycol price. However, the macro - sentiment has weakened slightly, and the chemical industry has followed the weakening of bulk commodities. Overseas ethylene glycol plant maintenance, especially in Saudi Arabia, has been continuously postponed, which may significantly affect the market. The future arrival volume of ethylene glycol has decreased. Polyester production and sales have weakened, downstream weaving profits have shrunk, and terminal loads have significantly declined, which is a negative impact on the market [2] Group 3: Summary by Relevant Catalogs 1.

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].

1. Report Industry Investment Rating - No relevant information provided 2. Core View of the Report - The PTA market saw price increases due to a rebound in the crude oil market and production cuts at some PTA plants, but the spot basis weakened due to continuous shipments from major suppliers. The ethylene glycol market maintained a strong - side oscillation, with spot prices rising slightly and the basis negotiation strengthening. The polyester market faced a complex situation, with factors such as changes in raw material prices, production and sales rates, and inventory levels affecting the market [2]. 3.

Industry Investment Rating No relevant content provided. Core Views - PX: Supply and demand are weakening, and attention should be paid to warehouse receipt pressure. The unilateral trend is weak, and attention should be paid to warehouse receipt pressure and the roll - over of the main contract. The PXN has fallen from a high level, and the PX - MX spread has also declined but remains at a high level. Future Asian PX supply will gradually increase [3][4]. - PTA: Cost support is weak, and there is negative demand feedback. Attention should be paid to warehouse receipt pressure. The unilateral trend is weak, and short positions should be held. The spot processing fee remains low, and the basis and monthly spread are both weak [5]. - MEG: The unilateral trend is weak, and attention should be paid to the opportunity of positive monthly spread arbitrage. The profit of coal - based MEG plants has recovered, and the production of some ethylene oxide plants will be converted to MEG in the future [6]. Summary by Directory PX Valuation and Profit - PX unilateral price has dropped significantly, and the structure has gradually become flat. The PXN has fallen from a high level, and the PX - MX spread has also declined but remains high. Asian gasoline cracking spreads are weak, and the toluene disproportionation spread has weakened, while the toluene blending profit has recovered. The aromatics blending economy has improved [20][23][24]. Supply and Demand - China's PX operating rate is 81.1% (+1.2%), and Asia's overall operating rate is 73.4% (+0.5%). There is no new PX maintenance in China in August, and some plants are restarting. Future Asian PX supply will gradually increase. PTA device operating rate is expected to decline in August, which means reduced demand for PX [3][42]. Inventory - In July, the monthly PX inventory in Longzhong dropped to 414 tons (-24) [65]. PTA Valuation and Profit - The spot supply is increasing, the basis is in a reverse arbitrage situation, and attention should be paid to the opportunity of positive monthly spread arbitrage at low levels. The spot processing fee remains at a low level, and some plants have unplanned maintenance [71][82]. Supply and Demand - The PTA device operating rate remains at 75.3% (-4.4%) and is expected to continue to decline in August. Some plants have stopped production or reduced loads. PTA exports are expected to increase in July - August, and port inventories are rising, but the total inventory accumulation is lower than expected [86][92][105]. Inventory - PTA port inventories are rising, but the cumulative increase in total inventory is lower than expected [105]. MEG Valuation and Profit - The unilateral valuation is in a volatile market, the monthly spread has declined, and the downward space is limited. The relative valuation of MEG compared to ethylene oxide, styrene, and plastics has risen to a high level this year, and the profits of each link have significantly recovered [125][129][132]. Supply and Demand - The operating rate of MEG continues to rise. Overseas, some plants are operating at low loads or under maintenance, and imports will remain high. Domestic coal - based MEG device operating rate is 75% (+0.6%), and future loads will continue to rise [135][136]. Inventory - No relevant content provided. 2025 PX - PTA - Polyester Production Plan - PX will have a new production capacity of 300 tons from Yulong Petrochemical in the second half of the year. - PTA will have new production capacities of 600 tons from Sanfangxiang and Xin Fengming in the second half of the year. - MEG will have new production capacities of 100 tons from Yulong Petrochemical and others in the second half of the year. - Polyester will have new production capacities of 305 tons from Anhui Youshun and others throughout the year [8].
