Cost and Supply Disruption Drive Ethylene Glycol Past 6,000 Yuan: A Repricing Challenge for the Chemical Fiber Chain

When the main ethylene glycol futures contract broke through the 5,500, 5,800, and 6,000 yuan thresholds within less than a month, and hit 6,046 yuan per ton on September 9, every link in the polyester chain felt the scorching heat on the cost side. This price refreshed the record since October 2021, meaning the price ceiling accumulated over the past five years was pierced in one go. For downstream weaving and fabric enterprises, this is not just a swelling raw material bill but a recalibration of inventory strategies and order quotations.

Event Background

The trigger for this round of ethylene glycol rally is the resonance of geopolitical risk and crude oil costs. The conflict in the Middle East escalated again when Iran's Foreign Ministry issued a statement on the 9th condemning U.S. attacks on Iranian vessels, followed by Iranian armed forces striking U.S. military bases and ships. After the news, international oil prices surged, directly raising production costs for ethylene glycol, which uses naphtha as a feedstock. The cost-side push is not an isolated event; supply-side contraction intensified the rally. Since the outbreak of the Middle East conflict, navigation risks in the Strait of Hormuz have risen, blocking ethylene glycol import channels and significantly reducing import volumes. China's ethylene glycol import dependence has long exceeded 50%, with the Middle East accounting for a considerable share. The expectation of import disruption quickly reflected in the futures market.

Industry Impact

The rise in ethylene glycol is not an isolated incident but the starting point for cost transmission across the entire polyester chain. As the direct upstream of PTA and polyester filament, every 100 yuan per ton increase in ethylene glycol theoretically raises polyester filament costs by about 30-40 yuan per ton. Against a backdrop of weak demand recovery, cost-push inflation is a double-edged sword for polyester plants: on one hand, they can take the opportunity to raise product quotes and alleviate earlier losses; on the other, if downstream weaving enterprises resist high prices, inventory pressure will accumulate inversely. Historical experience shows that when ethylene glycol prices are above 6,000 yuan, the cash flow of polyester plants tends to weaken, and industry operating rates may adjust accordingly.

For weaving and fabric buyers, the impact of raw material price increases is not immediate but manifests as delayed quote adjustments. Typically, polyester filament price adjustments lag by one to two weeks, meaning current orders may not fully reflect the ethylene glycol increase. If geopolitical tensions persist, raw material costs could rise further, and low-priced orders placed earlier may face delivery losses. For foreign trade enterprises, the combination of RMB exchange rate fluctuations and raw material price increases squeezes profits of export orders denominated in USD, and the window for price adjustments is narrowing.

Practical Recommendations

For Buyers - Moderately increase raw material inventory to 2-3 weeks of usage to lock in current relatively low prices, but avoid overstocking to prevent losses from price corrections. - Sign short-term floating price contracts with suppliers, incorporating an ethylene glycol price index into pricing formulas to reduce unilateral fluctuation risk. - Monitor Middle East situations and crude oil inventory data, establish a price warning mechanism, and trigger replenishment or wait-and-see decisions at key levels (e.g., ethylene glycol at 6,000 yuan/ton).

For Foreign Trade Enterprises - Include raw material price adjustment clauses in new order quotes, specifying that if ethylene glycol or PTA prices fluctuate beyond a certain range, price renegotiation can be initiated. - Shorten quote validity to 5-7 days to reduce cost change risk between quotation and contract signing. - Use futures hedging tools to lock in long-term raw material costs, hedging against price volatility caused by geopolitical events.
