Port inventory of 86,000 tonnes. Just months ago, that figure stood at 975,000 tonnes. China's visible MEG stocks have collapsed by more than 90% in a matter of months, igniting bullish sentiment across the chemical complex. But a sharp inventory drawdown does not automatically signal robust demand. It reflects, more than anything, a passive destocking driven by disrupted import flows. With Brent crude back above $101 per barrel and WTI at $89, the question is whether MEG can ride the cost-side tailwind into a sustained rally. The answer requires unpacking both supply and demand.
The Two Faces of Supply
Escalating geopolitical tensions in the Middle East are the immediate driver behind the inventory decline. The Strait of Hormuz handles a substantial share of MEG chemical exports, and concerns over shipping disruptions have visibly slowed cargo departures from the region, with schedule delays becoming increasingly likely. Industry data suggests China's MEG imports will remain subdued through the fourth quarter, keeping port stocks at depressed levels. The price floor provided by low inventory is real, and it is the bulls' most direct argument.
Yet the other side of supply is equally clear. Domestic MEG plant utilization currently sits at 65.92%, with coal-based units running at around 71% on improved production margins. More critically, two large plants are slated to come online in Q4. This means the gap left by reduced imports could be filled quickly by domestic capacity. For factories, the supply-side bullish case is not linearly diminishing. It can reverse at any moment when new capacity is released.
Demand Remains the Real Ceiling
Polyester is the core variable determining whether MEG's price uptrend can be sustained. Q4 marks the seasonal transition window for polyester, with the traditional peak season winding down and terminal textile orders losing momentum. Facing relatively high MEG feedstock costs, polyester plants are under mounting cost pressure. Downstream resistance to high-priced raw materials is strong, with purchasing largely limited to just-in-time buying. Willingness to build large inventories is notably absent.
Weaving orders remain weak, and finished goods inventory destocking is under pressure, making it difficult for the supply chain to pass through raw material price increases. Meanwhile, tight PX supply in Q4 is forcing many polyester enterprises to cut operating rates. Once polyester utilization declines, it directly reduces MEG consumption. Even if MEG supply contracts temporarily, without a substantive recovery in terminal textile consumption, polyester producers cannot sustain high feedstock costs for long and may further reduce output, dragging down MEG demand.
Price Outlook and Supply Chain Transmission
In sum, rising oil prices, geopolitical disruption, and low port inventory provide short-term support for MEG, giving prices a foundation for range-bound strength. But supply-side bullish factors alone are unlikely to drive a sustained one-way rally. The upside will depend on two key variables: first, changes in Middle East shipping and the pace of new domestic plant startups; second, whether terminal textile orders improve and polyester can maintain stable operations. If downstream demand fails to materialize and negative feedback intensifies, MEG's upside will be significantly capped.
For traders, the current MEG market structure resembles an event-driven rebound rather than a trend reversal. Low inventory provides a price floor, but rallies lacking demand-side confirmation tend to have limited staying power. Once Middle East shipping expectations ease or new plants commence operations, the supply-side premium could fade quickly.
