Crude oil has climbed back above triple digits, yet MEG has not followed with a one-way rally. That divergence is itself the most telling signal in the polyester feedstock market this quarter. Brent and New York crude both extended gains beyond 1%, lifting cost-side sentiment, but MEG pricing is no longer driven by crude alone.
Cost Support Meets Supply Contraction
Escalating tensions in the Middle East, where the Strait of Hormuz handles a large share of MEG chemical exports, are raising concerns over shipping disruptions and delayed cargoes. This geopolitical variable is directly reflected in domestic inventories: port MEG stocks have fallen from a first-half peak of 975,000 tonnes to 86,000 tonnes, a historically low level.
Low inventories mean solid support beneath spot prices. Q4 imports are expected to stay low, and domestic supply cannot fully fill the gap left by contracting imports in the near term. For traders, this structural tightness amplifies price sensitivity to sudden events; for downstream factories, it means shrinking room to negotiate on feedstock procurement.
But supply is not uniformly bullish. Domestic MEG plant operating rates remain at a relatively high 65.92%, with coal-based units running at around 71% driven by healthy margins. More critically, two large plants are scheduled to start up in Q4, giving domestic output considerable incremental flexibility.
This means the import gap will be partially offset by new domestic capacity. Once these plants come online, the release of domestic supply will pressure prices, making the supply-side tug-of-war more complex than it appears.
Demand Is the Real Ceiling
The key variable determining MEG's upside is not supply but downstream polyester. Q4 marks the seasonal transition window, with the traditional peak season winding down and terminal textile orders losing momentum. Weaving orders are weak, and finished goods inventory destocking remains under pressure.
Facing relatively high MEG prices, polyester plants are under mounting cost pressure. Downstream resistance to expensive feedstock is strong, with procurement largely limited to just-in-time buying rather than proactive stockpiling. Passing feedstock cost increases up the chain faces heavy resistance, which is the core constraint on MEG's sustained rally.
Compounding the issue, tight PX supply in Q4 is forcing many polyester enterprises to cut operating rates. Once polyester output declines, it directly reduces MEG consumption. Even if MEG supply contracts temporarily, without a substantive recovery in terminal textile consumption, polyester plants cannot sustain high feedstock costs for long and may further cut rates or undertake maintenance, dragging down MEG demand.
Once this negative feedback loop forms, MEG demand will face persistent headwinds. Short-term supply-side positives can support a mildly firm price range but are unlikely to drive a sustained one-way rally.
Two Variables to Watch
In summary, rising crude, geopolitical disruption, and low port inventories provide near-term support, giving prices a foundation for range-bound strength. But the extent of any further upside depends on two variables: first, supply changes from Middle East shipping conditions and the pace of new domestic plant startups; second, whether textile terminal orders improve and whether polyester can maintain stable operating rates.
If downstream demand fails to materialize and negative feedback intensifies, MEG's upside will be significantly compressed. For market participants, the focus now should be on timing rather than direction.
