International oil prices showed a rare one-way rally on the first trading day of September, with WTI crude rising 2% intraday to stand above $87 per barrel, while Brent crude strengthened in tandem, hitting an intraday high of $91.98 per barrel. For the textile industry, this is not merely an energy story—crude oil is the upstream feedstock for synthetic fibers such as polyester and nylon, and its price fluctuations often transmit to the polyester chain within days, affecting fabric costs and order quotations.
Background
The intraday pattern was not a straight-line rally but a 'ladder-like' climb. In early Asian trade, WTI hovered around $85 per barrel, then gradually advanced; in the afternoon, Brent first broke above $91, boosting sentiment; near the close, WTI accelerated and finally recorded a 2% daily gain. This phased strength usually indicates sustained buying rather than a single event-driven move.
For the chemical fiber industry, every $1 per barrel rise in crude increases PX cost by approximately $8-10 per ton, which in turn raises the theoretical cost of PTA and polyester chips. Based on current gains, the direct feedstock cost of polyester filament may increase by about 150-200 RMB per ton. However, transmission is not immediate—there is typically a 1-2 week lag from crude to polyester products, influenced by supply-demand, inventory levels, and processing spreads.
Industrial Impact
This oil price surge coincides with the 'golden September, silver October' stocking period for the polyester chain, but downstream responses are clearly divergent. Weaving clusters in Shengze and Changxing still hold high greige fabric inventories, with some mills running at around 70% capacity, purchasing raw materials mainly for just-in-time needs rather than panic stockpiling. Meanwhile, dyeing and finishing enterprises in the Xiaoshan-Shaoxing area face operating restrictions due to energy consumption control policies, suppressing demand for chemical fibers. This suggests that rising costs may squeeze polyester mills' processing margins rather than smoothly pass through to fabric prices.
From an international trade perspective, higher oil prices raise marine fuel costs, thereby affecting export freight. For orders settled on FOB or CFR terms, freight fluctuations could narrow actual profits. Additionally, if RMB depreciation occurs due to oil price rises, it would benefit exporters, but the current exchange rate remains relatively stable, making this factor insignificant for now. Notably, geopolitical risk premiums in the Middle East may persist; if oil breaks above $90 and holds, the willingness of the chemical fiber chain to support prices will strengthen significantly.
