The military conflict between the United States and Iran escalated sharply over the weekend, rapidly fueling concerns over international crude oil supply disruptions. Asian electronic markets opened significantly higher on Monday, and this cost-side shift did not stop at crude oil but quickly transmitted along the chemical chain to the polyester sector. Ethylene glycol led the gains, followed by PTA and polyester staple fiber, with overall increases exceeding 2%.
Geopolitical Shockwaves: How Crude Ignites the Polyester Chain
The immediate trigger for this market movement was the continued military conflict between the US and Iran over the weekend. As the Middle East is a major crude-producing region, any military confrontation triggers expectations of supply disruptions. Historical experience shows that such geopolitical events are often amplified by sentiment at market open, causing crude prices to jump in a short period, thereby pushing up costs for naphtha, PX, and other upstream polyester raw materials.
For the polyester chain, ethylene glycol and PTA are core raw materials, and their price fluctuations are highly correlated with crude oil trends. Ethylene glycol's leadership in gains reflects the market's most direct stress response to cost-side pressures. Notably, the broad-based rise in polyester chain varieties is not demand-driven but purely a cost push from the supply side. This means that if the geopolitical situation does not quickly de-escalate, upstream cost pressures will continue to transmit downstream.
Cost Transmission Path: The Time Lag from Raw Materials to Fabric
Cost transmission along the polyester chain typically takes one to two weeks. A rise in crude prices first pushes up naphtha and PX prices, then increases production costs for PTA and ethylene glycol, and finally transmits to polyester chips, polyester filament yarn, and polyester staple fiber. For fabric and apparel buyers, the current market reaction is seen in futures and spot markets, but actual procurement cost impacts will gradually materialize over the next two weeks.
Industry public data show that profit distribution in the polyester chain has long followed a pattern of "fat upstream, thin downstream." Upstream PX and PTA segments are highly concentrated with strong pricing power, while downstream weaving and apparel segments are highly competitive with already thin profit margins. This sudden cost-side strength puts downstream companies in a dilemma: accept price hikes to compress their own profits, or seek alternative raw materials, but with polyester accounting for nearly 80% of chemical fiber production, substitution options are limited.
Industrial Belt Reactions: Order Rhythms May Adjust in Shengze, Keqiao
Textile industry clusters such as Shengze in Jiangsu and Keqiao in Zhejiang are major consumers of polyester raw materials. This cost increase has the most direct impact on weaving enterprises in these areas. The current period is a transitional phase between the traditional off-season and peak season in the third quarter, when companies typically stock up on raw materials for autumn and winter orders. The sudden cost spike may lead some companies to postpone raw material purchases and adopt a wait-and-see approach, temporarily dampening demand.
From a foreign trade perspective, the combination of RMB exchange rate fluctuations and rising raw material prices makes it more difficult for export companies to set prices. Overseas buyers are highly price-sensitive and may tend to reduce order sizes or extend negotiation cycles in the short term. For export companies focused on polyester fabrics, it is crucial to closely monitor geopolitical developments and include price adjustment clauses in contracts to hedge risks.
