International oil prices staged a sharp rally on the first trading day of September, with WTI crude rising 2% to $87.12 per barrel and Brent climbing 1.84% to $91.98. For the textile industry, this is not just an energy flash but a clear signal from the cost side of the polyester chain. When crude oscillates between $86 and $91 and then breaks upward, the pricing logic of PTA, MEG, and polyester filament will be recalibrated.
The Timing Gap in Cost Transmission
The impact of oil price increases on textile raw materials is not simultaneous. Historically, crude price moves take about a week to transmit to PTA, and another two to three weeks to reach polyester filament and fabric prices. Currently, the industry is in the 'golden September, silver October' restocking period, with weaving mill operating rates at relatively high levels, but terminal orders have not surged. This creates a window between cost-push and demand absorption.
During this window, the pricing strategy of polyester plants is crucial. If oil remains high, PTA processing spreads may compress, prompting plants to raise polyester filament ex-factory prices to pass on costs. However, downstream grey fabric inventories are still being drawn down, and fabric buyers have limited acceptance of price hikes. Public industry data shows that polyester filament sales ratios in Jiangsu and Zhejiang regions are only 60-80%, indicating weak follow-through on price increases.
Divergent Reactions Across Industrial Clusters
Oil shocks affect different industrial clusters unevenly. Clusters like Shengze and Changxing, which rely heavily on polyester raw materials, are most sensitive to oil fluctuations, with local traders adjusting price expectations on the same day. In contrast, clusters like Keqiao and Nantong, focused on fabrics and home textiles, react with a lag, sensing changes indirectly through grey fabric procurement costs. This timing difference creates arbitrage opportunities for enterprises with inventory management capabilities.
For buyers, the main risk is 'self-fulfilling' price hikes. If polyester plants raise prices consecutively, some traders may hoard supplies, further pushing up short-term prices. But given weak downstream demand, such increases lack fundamental support and may face a pullback. Historical experience shows that in a weak demand environment, the pass-through rate of raw material price increases to fabric prices is typically less than 50%.
The Game in Foreign Trade Pricing
For export-oriented textile companies, oil price increases also imply dual pressures from freight and exchange rates. Although this oil fluctuation has not yet triggered major shipping rate adjustments, if Brent stays above $90, rising bunker fuel costs will gradually reflect in freight quotes. Meanwhile, if the RMB depreciates due to higher oil prices, it may partially offset cost increases for exporters.
The pricing mechanism for foreign trade contracts becomes delicate. Long-term customers usually lock prices quarterly or semi-annually, making immediate pass-through difficult. Short-term and spot orders may feel raw material cost changes within a week. It is recommended that foreign trade enterprises include floating clauses in quotes or smooth volatility through forward exchange contracts and raw material hedging. Public data shows that since 2025, over 30% of textile foreign trade enterprises have used hedging tools to manage cost risks.
