On July 21, the international crude oil market experienced a period of intense and rapid price surges. WTI crude rose from the $83 range to $85.40 per barrel within hours, expanding its intraday gain to 3%; Brent crude strengthened in tandem, rising over 2% intraday and briefly touching $89.4 per barrel. For the textile industry, these numbers represent more than just futures volatility—they signal a new round of cost pressure on chemical fibers.
Cost Transmission: How Short Is the Chain from Crude to Polyester?
Crude oil is the most upstream raw material in the polyester value chain. Industry data shows that for every $1/barrel change in crude oil, the cost impact on PTA is approximately 35-40 yuan/ton, which further translates into a 50-60 yuan/ton cost change for polyester filament and staple fiber. The single-day jump of about $2.5/barrel in WTI implies a theoretical cost increase of 120-150 yuan/ton on the polyester side. In the thin-margin era of chemical fibers, this amount is almost equivalent to the entire processing profit for some conventional grades.
What deserves more attention is the speed of transmission. Most polyester plants currently maintain raw material inventories at a low level of 7-10 days, meaning the signal of rising oil prices will be felt by weaving mills almost instantly. Unlike the period of sharp oil price fluctuations in 2022, when the chain still had high-cost inventory buffers, by 2025 most textile mills have adopted a "buy-as-you-use" strategy, leaving almost no time lag for price transmission.
Industry Impact: Intensified Game Under Low Inventories
The timing of this oil price surge is particularly sensitive. July is traditionally the transition period between the off-season and peak season for textiles, with downstream weaving utilization rates around 60% and raw material procurement mostly for immediate needs. The sudden spike in oil prices will force polyester plants into a dilemma: if they follow the price increase, they may dampen already weak purchasing intentions; if they do not, their processing margins will be further squeezed.
From the market perspective, Brent crude oscillated in the $87-89 range before finally closing at $89.4, indicating that bullish forces remain dominant. For textile foreign trade enterprises, rising raw material costs denominated in US dollars, coupled with RMB exchange rate fluctuations, are narrowing the window for adjusting export quotations. Especially for conventional polyester taffeta and pongee orders targeting Southeast Asian markets, where price competition is already fierce, any cost-side anomaly could directly erode order profitability.
