1. Report Industry Investment Ratings - No investment ratings are provided in the reports. 2. Core Views of the Reports Polyester Industry - PX: Supply is expected to increase as maintenance devices restart, but demand may weaken. However, with the approaching peak season, the demand may strengthen. Short - term PX11 can be overweighted in the chemical sector, and the PX - SC spread can be widened [2]. - PTA: Supply is affected by planned outages due to low processing fees, but demand may pick up. It can be overweighted in the chemical sector, and TA1 - 5 may show a positive spread repair in the short - term [2]. - Ethylene Glycol: Domestic supply increases, port inventory is low, and demand is expected to improve. Short - term put option EG2601 - P - 4350 sellers can hold [2]. - Short - fiber: Supply increases as maintenance devices restart, and demand may improve with the approaching peak season, but the sustainability of downstream restocking is weak. PF10 can be overweighted in the chemical sector [2]. - Bottle - chip: In the peak consumption season, production cuts lead to inventory reduction, but the cost increase suppresses processing fees. PR is similar to PTA, and the main contract processing fee is expected to fluctuate between 350 - 500 yuan/ton [2]. Polyolefin Industry - PP: The price center moves down, and the weighted profit is compressed. The supply and demand both increase, achieving de - stocking. The LPO1 spread can be held [7]. - PE: The price is stable with a downward trend.

At the end of the off - season, the overall production start - up rate of the three S products on the demand side fluctuated upward [13][15] Polyolefins Polyethylene - **Market Quotes**: The futures price of polyethylene rose [17] - **Fundamentals**: The market was expecting favorable policies from the Chinese Ministry of Finance in the third quarter, and there was still support on the cost side. The polyethylene spot price remained unchanged, and the PE valuation had limited downward space. The overall inventory decreased from a high level, providing support for the price. The seasonal peak season was approaching, and the raw material procurement for agricultural films on the demand side had started. The overall production start - up rate fluctuated at a low level and stabilized [17] Polypropylene - **Market Quotes**: The futures price of polypropylene rose [18] - **Fundamentals**: The profit of Shandong refineries stopped falling and rebounded, and the production start - up rate was expected to gradually recover, leading to a marginal increase in propylene supply. On the demand side, the downstream production start - up rate fluctuated at a low level. In August, there were only 450,000 tons of planned polypropylene production capacity to be put into operation. Although the seasonal peak season might be approaching, under the background of weak supply and demand, the overall inventory pressure was high, and there was no prominent short - term contradiction [18] PX, PTA, and Ethylene Glycol PX - **Market Quotes**: The PX11 contract rose 4 yuan to 6,970 yuan, the PX CFR rose 2 dollars to 859 dollars, the basis was 76 yuan (- 3), and the 11 - 1 spread was 68 yuan (+ 2) [20] - **Fundamentals**: In terms of PX load, China's load was 84.6%, up 0.3%; Asia's load was 76.3%, up 2.2%. There were few changes in domestic plants, while overseas, a 530,000 - ton plant in Thailand and a 1.34 - million - ton plant in Saudi Arabia restarted. The PTA load was 72.9%, down 3.5%. In terms of plants, Jiayuan reduced its load and then recovered, Jiaxing Petrochemical's extended - maintenance plant was restarting, Hainan Yisheng was under maintenance, Hengli Huizhou had an unplanned shutdown, and the second line of Hailun Petrochemical was put into operation. In terms of imports, South Korea exported 294,000 tons of PX to China in the first and middle ten - days of August, a year - on - year increase of 55,000 tons. The inventory at the end of June was 4.138 million tons, a 210,000 - ton decrease from the previous month. In terms of valuation and cost, PXN was 270 dollars (0), and the naphtha cracking spread was 94 dollars (+ 6). Currently, the PX load remained at a high level, and there were many short - term unexpected maintenance situations for downstream PTA, so the overall load center was relatively low. However, due to the commissioning of new PTA plants, PX was expected to maintain low inventory, and there was support for the valuation at the lower end. Moreover, the terminal and polyester data were gradually improving, releasing the upstream valuation space. The current valuation was at a neutral level, and the terminal and polyester sectors were expected to continue to recover [20] PTA - **Market Quotes**: The PTA01 contract fell 6 yuan to 4,862 yuan, the East China spot price fell 20 yuan/ton to 4,850 yuan, the basis was 22 yuan (0), and the 9 - 1 spread was - 34 yuan (- 14) [22] - **Fundamentals**: The PTA load was 72.9%, down 3.5%. In terms of plants, Jiayuan reduced its load and then recovered, Jiaxing Petrochemical's extended - maintenance plant was restarting, Hainan Yisheng was under maintenance, Hengli Huizhou had an unplanned shutdown, and the second line of Hailun Petrochemical was put into operation. The downstream load was 90%, up 0.6%. In terms of plants, the load of some local plants increased. The terminal texturing load increased by 7% to 79%, and the loom load increased by 5% to 68%. As of August 15, the social inventory (excluding credit warehouse receipts) was 2.25 million tons, a 23,000 - ton decrease. In terms of valuation and cost, the PTA spot processing fee fell 20 yuan to 228 yuan, and the futures processing fee fell 7 yuan to 334 yuan. In the future, on the supply side, the unexpected maintenance volume in August increased, and the inventory - building pattern changed to inventory - reduction. The PTA processing fee was expected to continue to recover. On the demand side, the inventory pressure of polyester fibers decreased, and the downstream and terminal production start - up rates improved, releasing the upstream valuation space. In terms of valuation, PXN had the momentum to rise supported by the improved situation brought about by PTA commissioning. Recently, the valuation expanded due to the boost from unexpected PTA maintenance. It was recommended to follow PX and go long at low prices after the peak - season downstream performance improved [22] Ethylene Glycol - **Market Quotes**: The EG01 contract rose 35 yuan to 4,509 yuan, the East China spot price rose 24 yuan to 4,542 yuan, the basis was 98 yuan (+ 6), and the 9 - 1 spread was - 59 yuan (- 5) [23] - **Fundamentals**: On the supply side, the ethylene glycol load was 73.2%, up 6.2%. Among them, the synthetic - gas - based production load was 81.3%, up 0.8%; the ethylene - based production load was 68.3%, up 9.4%. In terms of synthetic - gas - based plants, Tianying restarted, Jianyuan reduced its load, Guanghui, Meijin, and Sinochem increased their loads, and Shaanxi Weihua was under maintenance. In the oil - chemical sector, one of Shenghong's plants restarted, and Zhejiang Petrochemical increased its load. Overseas, Lotte in the United States and Petronas in Malaysia restarted. The downstream load was 90%, up 0.6%. In terms of plants, the load of some local plants increased. The terminal texturing load increased by 7% to 79%, and the loom load increased by 5% to 68%. The import arrival forecast was 54,000 tons, and the average daily departure volume from East China ports from August 22 - 24 was 14,000 tons. The port inventory was 50 tons, a 47,000 - ton decrease. In terms of valuation and cost, the profit of naphtha - based production was - 384 yuan, the profit of domestic ethylene - based production was - 569 yuan, and the profit of coal - based production was 1,104 yuan. The cost of ethylene remained unchanged at 830 dollars, and the price of Yulin pit - mouth bituminous coal fines decreased to 520 yuan. In terms of industry fundamentals, overseas and domestic maintenance plants were gradually restarting, and the downstream production start - up rate was gradually recovering from the off - season, but the supply was still in excess. It was expected that the port inventory would enter an inventory - building cycle in the medium - term. The valuation was relatively high compared to the same period, the fundamentals changed from strong to weak. Although there was short - term support from less arrival volume and policy sentiment, there was downward pressure on the medium - term valuation [23]

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints MEG - MEG is expected to maintain an upward - biased and hard - to - fall trend in the short term. Although it is in a pattern of inventory accumulation, the low inventory, low valuation, and inelastic supply make it likely to rise. Operationally, it is recommended to go long on dips within the range. In the medium - to - long term, the performance of the downstream polyester peak season needs to be observed, and long positions can be hedged by selling out - of - the - money near - month call options [1][3]. PX - TA - The supply reduction of PX - TA has pushed up the PTA price. In the short term, the unexpected device events cannot change the long - term relatively oversupplied pattern. The processing fee of PTA is expected to be under long - term pressure. Operationally, the processing fee should be shorted on rallies, and the 1 - 5 reverse spread can be moderately shorted on rallies [5][7]. 3.

Core Viewpoint - The polyester sector has experienced a rebound since August 15, driven by multiple factors including stable oil and coal prices, low inventory levels of key raw materials, and an approaching demand peak season [1][2]. Group 1: Market Dynamics - The recent price increase in the polyester sector is supported by stable oil and coal prices, which have rebounded, and the sector's long-term low valuation limits further downside potential [1]. - The inventory levels of key raw materials such as PX, PTA, and MEG are currently low, which, combined with the upcoming demand peak season, provides strong upward price elasticity if unexpected positive factors arise [1]. - The demand side is transitioning from a low to a high season, with weaving operating rates recovering to 63% and polyester operating rates increasing to 89.4% [2]. Group 2: Supply Chain Insights - The polyester industry is currently in a phase of orderly expansion, with upstream production of PX and short fibers being paused, while PTA and bottle-grade PET continue to see rapid capacity growth [2][3]. - The overall profit levels in the polyester supply chain remain low, with profits concentrating in the upstream due to differing production rhythms across the supply chain [2][3]. Group 3: Future Outlook - The current trading logic in the polyester sector reflects a contradiction between strong realities and weak expectations, with concerns about demand being dragged down by earlier "export rush" activities [3]. - Short-term expectations suggest that the polyester sector may experience a pattern of easy price increases but difficult declines, while long-term price strength will depend on cost stability, supply-demand dynamics, and macroeconomic sentiment [3]. - Analysts predict a generally strong price trend for polyester until September, with a focus on valuation changes and the actual impact of supply-side factors thereafter [3].
