PTA：地缘影响下，PTA重心上移，MEG：供需由弱转强预期下，MEG反弹修复为主

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - PTA is expected to move up with the cost center in the short - term as international crude oil rises significantly, new PTA plants are put into operation and increase load gradually, domestic supply is expected to rise, and there is an expectation of polyester load reduction during the terminal seasonal off - season [6]. - Ethylene glycol is expected to rebound and repair in the short - term as the cost side moves up, some maintenance devices restart, imports may be affected by geopolitical factors, and there is a strong expectation of turning from weak to strong in supply - demand [6]. 3. Summary According to the Directory 3.1 Upstream Analysis of the Industrial Chain - Price Movement: Due to the smooth progress of Sino - US economic and trade talks, the continuation of the traditional fuel consumption peak season in the US, and the influence of the Middle East geopolitical situation, oil prices have risen significantly. As of June 13, the Asian PX closing price was at 854 US dollars/ton CFR China, up 36 US dollars/ton from May 30. However, the absolute price increase of PX was less than that of crude oil because multiple PX plants restarted and the downstream polyester performance was not ideal [16]. - Capacity Utilization: The weekly average capacity utilization rate of domestic PX was 87.27%, a week - on - week increase of 3.83%. The weekly average capacity utilization rate of Asian PX was 75.29%, a week - on - week increase of 2.81%. It is expected that next week's PX output will increase slightly compared with this week [20]. - Processing Fee: As of June 13, the PX - naphtha price spread was 233.3 US dollars/ton, down 24.5 US dollars/ton from June 6. With the rapid recovery of the supply side, the PX - naphtha price spread declined. It is expected that the processing fee will continue to decline next week [23]. 3.2 PTA Fundamental Analysis - Price Movement: Affected by the sharp rise of international crude oil due to the Middle East geopolitical situation at the end of the week, the absolute price of PTA followed the cost increase. As of June 13, the PTA spot price reached 5015 yuan/ton, and the spot basis was 2509 + 221 [27]. - Capacity Utilization: The weekly average capacity utilization rate of domestic PTA reached 83.25%, a week - on - week increase of 4.24%. In June, it is expected that the PTA capacity utilization rate will increase significantly as some devices have maintenance expectations and some are planned to restart [31]. - Processing Fee: This week, the PTA processing fee continued to rise. However, with new device production and the restart of previous maintenance devices, supply is expected to increase continuously. With poor terminal performance and strong polyester production reduction atmosphere, it is expected that the PTA processing fee will decline slightly next week [34]. - Supply - Demand Situation: In June, with the co - existence of PTA device maintenance and restart and the expectation of polyester load reduction, the PTA supply - demand will shift from destocking to a tight balance [35]. 3.3 MEG Fundamental Analysis - Price Movement: This week, Zhangjiagang ethylene glycol bottomed out and stabilized. Affected by the Middle East geopolitical situation at the end of the week, with the expectation of supply reduction and cost support, MEG slightly rose. As of June 13, the Zhangjiagang ethylene glycol price was 4426 yuan/ton, and the South China market delivery price was 4530 yuan/ton [41]. - Capacity Utilization: The total capacity utilization rate of ethylene glycol was 55.07%, a week - on - week increase of 2.71%. The output of domestic factories has increased this week as some coal - chemical factories restarted and some integrated maintenance devices resumed work [42]. - Inventory: As of June 12, the total MEG port inventory in the main ports of East China was 56.38 tons, an increase of 1.67 tons compared with June 9. As of June 18, 2025, the total expected arrival volume of ethylene glycol in East China was 9.88 tons [47]. - Production Profit: The profits of all Chinese ethylene glycol process samples declined across the board. As of June 13, the profit of naphtha - based ethylene glycol was - 87.69 US dollars/ton, a decrease of 11.02 US dollars/ton compared with last week; the profit of coal - based ethylene glycol was 72.85 yuan/ton, a decrease of 68.88 yuan/ton compared with last week [51]. 3.4 Downstream Demand Analysis of the Industrial Chain - Capacity Utilization: The weekly average capacity utilization rate of polyester was 88.73%, a week - on - week decrease of 0.44%. In June, it is expected that the monthly polyester output will decline significantly as supply reduction may be greater than increase due to poor demand and fewer days [53][58]. - Product Inventory: This week, the overall polyester production and sales were sluggish, and the industry inventory slightly increased [63]. - Cash Flow: Entering the traditional off - season, affected by weak terminal consumption, the polyester cash flow may continue to be compressed [66]. - Weaving Industry: As of June 12, the comprehensive starting rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 61.02%, a decrease of 0.24% compared with the previous period. The average order days of terminal weaving were 9.91 days, a decrease of 0.51 days compared with last week [71]. 3.5 Summary of the Polyester Industrial Chain Fundamentals - Cost Side: Oil prices have risen significantly, but the absolute price increase of PX is less than that of crude oil [74]. - Supply Side: PTA production increased significantly this week, and the ethylene glycol capacity utilization rate increased [74]. - Demand Side: The polyester capacity utilization rate declined slightly, and the weaving starting rate in the Jiangsu and Zhejiang regions decreased [74]. - Inventory: PTA supply - demand is expected to weaken, and the MEG port inventory in East China increased [74].
