International oil prices experienced a sharp fluctuation on August 7: Brent crude briefly fell below $82 per barrel intraday, and WTI dropped to $75.82, but both rebounded at the close, with NYMEX light crude settling at $78.18 per barrel, up 1.15%, and Brent at $83.55, up 1.29%. This first-fall-then-rise pattern means that expectations on the cost side are being repeatedly reassessed for the textile chemical fiber chain.
Background
The direct trigger for oil price volatility was changes in geopolitical news. US officials said talks between Oman and Iran on the Strait of Hormuz made progress, leading the market to expect reduced supply risks and causing an intraday drop. But pre-close buying pushed prices back up. For the textile industry, the real focus is not on a single day's rise or fall, but on the tug-of-war around $80, which is exactly the sensitive range for chemical fiber cost accounting.
From the perspective of industrial chain transmission, crude oil prices affect the cost of PTA through naphtha and PX, then transmit to polyester filament and staple fiber, and finally reflect in fabric prices. Similarly, MEG, another major chemical fiber raw material, is directly linked to oil prices. Therefore, every pulse-like fluctuation in international oil prices will transmit to polyester factory quotes within two weeks to a month.
Industrial Impact
For polyester factories, oil price uncertainty increases the difficulty of raw material procurement. When oil prices fall, factories often wait for lower costs, but if prices rebound too quickly, they face higher replenishment costs. The August 7 pattern of first falling then rising is a typical sample of this "expectation trap"—when prices briefly fell below $82, some factories may have locked in raw materials at low prices, and the closing price rebound means the profit margins of these orders are squeezed.
For downstream fabric enterprises, cost transmission has a time lag, but the trend impact cannot be ignored. If oil prices continue to run above $80, the price center of polyester filament will likely move up. For woven and knitted fabric mills that mainly use polyester and nylon, this means inventory management needs to be more refined—moderately increasing raw material reserves when oil prices are low may be an effective means to hedge cost risks.
In addition, oil price fluctuations affect the pricing strategy of foreign trade orders. Overseas customers usually lock in prices on a quarterly or semi-annual basis. If oil prices fluctuate significantly during the period, fixed quotes may cause additional costs for export enterprises. Therefore, adding price adjustment mechanisms in contract terms, or using forward exchange locking and raw material hedging tools, is becoming an increasingly common choice for foreign trade enterprises.
