1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - The overall trend of commodities is driven by macro - sentiment. PTA may experience a short - term decline from high levels under the expectation of a fall in commodity sentiment due to new device production and poor terminal performance. MEG is expected to mainly follow cost fluctuations in the short term, with its cost support limited and supply pressure postponed [6]. - The cost side shows that crude oil continues to fluctuate widely, and PX is expected to run warmly in the short term. The supply side of PTA remains stable, while the total supply of MEG is expected to increase. The demand side of polyester is expected to change little, and the terminal demand is weakly declining [6]. 3. Summary According to the Table of Contents 3.1 Upstream Industry Chain Analysis - **Market Review**: OPEC+ is still in the process of increasing production, and geopolitical tensions are easing, leading to a decline in international crude oil. PX prices increased slightly due to good commodity sentiment despite limited support from cost and a weakening naphtha [16]. - **Capacity Utilization**: Tianjin Petrochemical's maintenance led to a narrow decline in PX capacity utilization. The domestic PX weekly average capacity utilization was 82.81%, down 0.35% from last week, and the Asian PX weekly average capacity utilization was 72.87%, down 0.28% [21]. - **Price Spread**: The PX - naphtha price spread rebounded slightly as naphtha prices weakened and commodity sentiment was good in China. As of July 25, the PX - naphtha price spread was 292.5 dollars/ton, up 30.55 dollars/ton from July 18 [22]. 3.2 PTA Fundamental Analysis - **Market Review**: Driven by macro factors, PTA had a weak rebound. The supply was stable, demand shrank slightly, and the balance sheet continued to accumulate inventory. As of July 25, the PTA spot price was 4900 yuan/ton, and the spot basis was 2509 - 5 [27]. - **Capacity Utilization**: There were no significant changes in PTA devices this week, and the capacity utilization fluctuated narrowly at 80.76%, remaining flat compared to the previous period. In July, Helen Petrochemical plans to start production, and Hengli has a maintenance plan, so the PTA capacity utilization is expected to fluctuate slightly [30]. - **Processing Fee**: The PTA processing fee was significantly repaired. Although the balance sheet continued to accumulate inventory and downstream procurement enthusiasm was blocked, there was an expectation of increased maintenance at low processing fees, so the processing fee is expected to continue to be repaired at a low level next week [31]. - **Supply - Demand Situation**: In July, with the commissioning of new PTA devices and the implementation of polyester production cuts, the supply - demand of PTA turned to inventory accumulation [34]. 3.3 MEG Fundamental Analysis - **Market Review**: Driven by macro and cost factors, ethylene glycol rebounded significantly. After breaking through and rising, it entered a high - level volatile trend. As of July 25, the closing price of Zhangjiagang ethylene glycol was 4579 yuan/ton, and the delivered price in the South China market was 4580 yuan/ton [40]. - **Capacity Utilization**: Some devices reduced their loads, and the ethylene glycol capacity utilization decreased slightly. The total domestic ethylene glycol capacity utilization was 59.20%, up 0.71% compared to the previous period. In July, domestic production is expected to increase, and overall supply will increase slightly [44]. - **Port Inventory**: Due to weak terminal demand, the ethylene glycol port inventory fluctuated at a low level. As of July 24, the total ethylene glycol port inventory in the East China main port area was 47.5 tons, up 1.57 tons from July 21 [46]. - **Processing Profit**: Ethylene glycol rebounded from a low level, and processing profits increased across the board. As of July 25, the profit of naphtha - based ethylene glycol was - 81.9 dollars/ton, up 20.69 dollars/ton from last week, and the profit of coal - based ethylene glycol was 75.2 yuan/ton, up 35.73 yuan/ton from last week [51]. 3.4 Downstream Demand Side of the Industry Chain Analysis - **Capacity Utilization**: Due to large - scale production cuts, the polyester capacity utilization decreased slightly to 86.4%, down 0.29% from the previous period. It is expected that the domestic polyester supply will decline significantly next week [54]. - **Production Volume**: In July, due to the seasonal off - season and high cash - flow pressure, the polyester monthly output is expected to decline significantly [56]. - **Capacity Utilization of Different Products**: The capacity utilization of polyester products was differentiated. The weekly average capacity utilization of polyester filament was 92.09%, down 0.85% from the previous period; the average capacity utilization of polyester staple fiber was 84.78%, down 1.64% from the previous period; and the capacity utilization of fiber - grade polyester chips was 76.58%, up 0.22% from last week [61]. - **Inventory**: Due to downstream centralized replenishment, the inventory of polyester products decreased significantly [62]. - **Cash - Flow**: With the significant increase in raw material prices, the cash - flow of polyester products was compressed, and the cash - flow loss expanded [67]. - **Weaving Market**: The off - season atmosphere in the weaving market deepened, and the start - up rate continued to decline. As of July 24, the comprehensive start - up rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 55.59%, down 0.24% from the previous period, and the average terminal weaving order days were 6.94 days, a decrease of 0.33 days from last week [70]. 3.5 Summary of the Polyester Industry Chain Fundamentals - **Cost Side**: Crude oil declined, and PX prices increased slightly due to good commodity sentiment [72]. - **Supply Side**: The PTA capacity utilization remained flat, and the MEG capacity utilization increased slightly [72]. - **Demand Side**: The polyester capacity utilization decreased slightly, and the weaving industry start - up rate was low with weak terminal demand [72]. - **Inventory**: PTA inventory shifted from destocking to inventory accumulation, and the MEG port inventory in the East China main port area fluctuated [73].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Geopolitical disturbances, expectations of peak demand season, and crude oil supply pressure are in a state of mutual restraint, causing international oil prices to fluctuate at high levels. If geopolitical risks ease later, the downward pressure on oil prices will increase. The maintenance of Tianjin Petrochemical's PX plant has led to a contraction in the weekly domestic supply, while the operating rate of downstream PTA has remained stable. Boosted by the overall strong atmosphere in the commodity market, the PX processing fee has recovered on a month - on - month basis. However, on Friday, the market sentiment significantly cooled down, and the PX price weakened sharply, but the supply - demand fundamentals still provide some support at the lower end [8]. - The strengthening of cost support is the main driver for the rise in PTA prices this week. From the perspective of supply - demand, there have been limited changes in the domestic supply side, but the downstream demand has remained weak. The supply - demand has maintained a weak pattern, and inventories have continued to accumulate. The short - term weak trend is expected to continue. Recently, the PTA spot processing fee has been compressed to a low level of around 200 yuan/ton. Many large - scale plants are planning maintenance in August, and it is expected that the supply will decline. There is an expectation of marginal improvement in the supply - demand side, and the downward support is expected to strengthen, but close attention still needs to be paid to the trends on the cost side [8]. - Driven by the cost side this week, ethylene glycol has shown a strong performance. The increase in the ethylene glycol price has led to a slight recovery in the oil - based production profit, but the significant increase in coal prices has resulted in little change in the coal - based production profit. Ethylene glycol currently maintains a tight balance. The port inventory has slightly decreased compared to last week but has rebounded compared to the beginning of the week, with a limited inventory accumulation amplitude. Two Saudi plants have recently restarted, and it is expected that the subsequent arrival volume will gradually increase. Currently, the fundamental contradictions of ethylene glycol itself are not prominent, and the driving force mainly comes from the cost side. On Friday night, as the market sentiment cooled down and the prices of crude oil and coal weakened sharply, ethylene glycol also followed the cost decline [8]. - Although the cost - side prices have continued to rise, the processing fees of polyester downstream products have weakened on a month - on - month basis, highlighting the insufficient demand - side carrying capacity and weak performance. Overall, the supply - demand contradictions of short - fiber itself are not prominent. The improvement in the commodity atmosphere has stimulated short - term replenishment by downstream customers, and the inventory has decreased. Its price mainly fluctuates following the raw materials. The price of bottle - grade polyester chips has been oscillating strongly supported by the cost. Its operating rate has slightly decreased, and the marginal changes in supply - demand are limited. The short - term trend also mainly follows the upstream costs [8]. - The weak situation of the polyester industry itself remains unchanged. The polyester operating rate has continuously declined, and the weaving operating rate and textile orders have only maintained a low - level operation. The fundamental support is weak, and the expectations are also weak. This week, driven by the overall commodity sentiment, the prices of polyester industry chain products have shown a strong performance. However, on Friday night, the market sentiment declined. In terms of operation, attention can be paid to the short - selling opportunities that may arise when the fundamental driving force and price trend return to synchronization [8]. Summary by Relevant Catalogs Price Changes of Polyester Industry Chain Products - From July 18th to July 25th, NYMEX crude oil futures decreased from $66.03/barrel to $65.07/barrel, a decrease of $0.96/barrel or 1.5%; ICE Brent crude oil futures decreased from $69.23/barrel to $67.6/barrel, a decrease of $1.63/barrel or 2.4%; domestic crude oil futures decreased from 532 yuan/barrel to 512.9 yuan/barrel, a decrease of 19.1 yuan/barrel or 3.6%.
