Brent crude has broken above the $100 mark, yet the polyester chain has not delivered the vigorous rally many had hoped for. Futures surged collectively before paring gains in the afternoon, with PX closing up over 2%, but the sustainability of spot price increases remains questionable. The core contradiction in this round lies not in demand, but in the convergence of raw material supply dynamics and geopolitical risk.
Raw Materials: A Tug-of-War Between Supply Recovery and Geopolitical Constraints
Domestic PX operating rates have rebounded sharply from below 60% to around 77%, driven primarily by the restart of units at Weilian, Shenghong, and Fuhua. Asian plant rates have also improved somewhat, and Huajin Aramco's new PX facility is expected to come online in October-November. In mid-to-late September, additional restarts are planned at Fuhua, Hainan Refining, and Yangzi Petrochemical, while Urumqi Petrochemical will shut for two weeks. Domestic supply is poised to rise further, but Asian refiners face feedstock constraints due to strait navigation restrictions, making a significant load increase difficult. This suggests the slope of PX supply recovery may be gentler than the market anticipates.
On the PTA side, the restart of previously idled units continues. Facilities at Dushan Energy, Yisheng New Materials, and Jiaxing Petrochemical have progressively resumed operations, pushing PTA loads noticeably higher and gradually revealing supply pressure. Processing fees have consequently fallen to around 400 yuan per ton, a level approaching the break-even point for some high-cost plants. For factories, sustained fee compression means production enthusiasm will be materially suppressed, and more units may join the减产 ranks in the coming weeks.
MEG finds itself in a more peculiar situation. Widespread shutdowns in the Middle East and restricted strait navigation continue to constrain supply, and the import gap is difficult to fill from domestic idle capacity or other regions. Since the second quarter, sharply reduced import volumes have kept the market tight. Geopolitical tensions have repeatedly delayed expectations for MEG import recovery, and imports are expected to remain below 200,000 tons in September-October, keeping spot liquidity tight. MEG's sensitivity to geopolitical shifts far exceeds that of PX and PTA, meaning any marginal change in Middle East tensions could trigger violent price swings.
Downstream: Production Cuts Force the Pace, Procurement Turns Impulsive
Polyester downstream performance remains sluggish, with operating rates continuing to decline. Staple fiber and bottle chip have seen the most pronounced reductions. Since mid-August, profits have been continuously squeezed, and processing fees have hit new lows, forcing more enterprises to cut production. Staple fiber operating rates have fallen to around 70%, while bottle chip plant rates have dropped to a historic low of around 60%. These two categories directly serve end consumption, and their sharp operating rate declines reflect weakness in both domestic demand and export orders.
Against a backdrop of recurring geopolitical tensions and high raw material price volatility, downstream polyester players are making impulsive purchases with a cautious mindset, reluctant to build regular inventories. September polyester loads are expected to remain below 80%, and peak season performance is likely to fall short of expectations. The traditional "Golden September and Silver October" luster is being eroded by both high costs and weak demand. For buyers, the current passive rise in raw material prices is not demand-driven, making chasing highs risky. For factories, compressed processing fees and insufficient orders mean cash flow management matters more than betting on market direction.
Outlook: Geopolitics Is the Biggest Variable
Although polyester chain demand is currently lackluster, futures and spot prices are being passively lifted by continuously rising costs. Middle East geopolitical disruptions are unlikely to dissipate in the short term, and the polyester market is expected to remain relatively strong on cost support. However, it is worth noting that this "cost-push" rally lacks demand-side cooperation. Once geopolitical tensions ease, suppressed downstream demand could rebound and boost the market. Conversely, if strait navigation issues become prolonged, the MEG supply gap will widen further, potentially forcing the polyester chain's cost center upward.
For all links in the supply chain, the most rational strategy now is not to bet on a one-sided market, but to prepare scenario plans: how to quickly restock if tensions ease, and how to lock in raw material costs if they worsen.
