Despite a collective rally in the polyester chain, ethylene glycol futures unexpectedly retreated in the afternoon, settling at 5,364 yuan/ton, up only 0.75%. This high-level volatility, ostensibly driven by capital games, actually reflects a fierce collision of bullish and bearish logics. Low inventories and high costs form a solid floor, but weak demand and geopolitical uncertainty cap the upside.
Inventory and Supply: The Fragility of Tight Balance
As of August 20, MEG inventory at East China main ports stood at only 268,000 tons, down 37,000 tons from the previous week, hitting a historic low. Behind this figure lies the dual squeeze of concentrated domestic maintenance and disrupted imports. August is the peak maintenance season, with multiple large units shut down, dragging the overall operating rate to 53.86%, the lowest for the same period in recent years. Although some units are scheduled to restart in late August, the short-term increase is limited and unlikely to materially ease supply tightness.
The contraction on the import side is even sharper. Due to the Middle East conflict, passage through the Strait of Hormuz has been hindered. While July imports rebounded marginally to 260,000 tons, August is expected to fall below 200,000 tons again. Compared with the average monthly import volume of 600,000 tons in previous years, the current supply gap is evident. More critically, there is no timeline for resuming navigation, and September imports are likely to remain low, meaning the destocking cycle may extend further.
Cost and Price: Transmission and Resistance of Geopolitical Premium
International oil prices have risen on geopolitical risk premiums, with Brent crude breaking above $90/barrel, hitting a stage high. Naphtha, ethylene, and other feedstocks followed suit, raising production costs across all ethylene glycol routes. The cost increase provides bottom support for the futures market, but whether prices can be passed through depends on downstream acceptance. Currently, polyester demand has not fully started, with traditional peak-season orders expected to be delayed until September, and overseas bulk orders also waiting for the strait to reopen and costs to stabilize.
This pattern of "cost-push, demand-lag" makes ethylene glycol prices prone to rise but hard to fall, while upside is constrained by weak end-use consumption. Once navigation resumes, export orders are likely to be released intensively, significantly improving price transmission efficiency. In essence, the current high-level consolidation reflects the market waiting for confirmation signals from the demand side.
Industry Impact: A Chance to Reshape Profit Distribution
The longer low inventories and high costs persist, the greater the impact on profit distribution across the industrial chain. Upstream ethylene glycol producers still have decent profit margins under cost support, but midstream polyester plants face the dual squeeze of rising raw material prices and sluggish product price increases, intensifying cash flow pressure. This pressure is transmitting upstream, forcing the exit of some obsolete capacity or accelerating industry consolidation.
For downstream textile enterprises, raw material price fluctuations directly affect order profitability. The current spot reference range is 6,200-6,400 yuan/ton, with futures at a significant discount, reflecting market optimism about far-month supply. However, if imports remain disrupted, spot premiums may widen, passively raising procurement costs.
