On the evening of July 15, international crude oil markets experienced a sharp decline. WTI crude fell over 1% intraday to close at $78.37/barrel, while Brent crude broke below the $83/barrel mark with a daily drop of 1.84%. For the textile industry, this is no mere futures fluctuation—it directly shakes the cost foundation of the polyester chain.
Cost Transmission: Short-Chain Impact from Oil to Chemical Fiber
Crude oil is the source of the polyester chain. The pricing logic of PTA, MEG, and downstream polyester filament yarn (POY, FDY, DTY) and polyester staple fiber moves almost in sync with oil prices. A single-day Brent decline of nearly 2% implies that the cost center of polyester raw materials may shift downward by approximately 1.5%-2%. For chemical fiber plants, this means inventory value erosion and disrupted procurement rhythms; for weaving mills, it may signal a temporary reduction in raw material procurement costs.
According to industry public data, the polyester chain in the first half of 2026 was generally characterized by high operating rates and low margins. The cash flow for each variety of polyester filament yarn—POY, FDY, DTY—hovered near the breakeven point. The sharp drop in oil prices could temporarily relieve the raw material cost pressure on chemical fiber plants, but it also exacerbates market wait-and-see sentiment—buyers tend to wait for lower prices, leading to a short-term contraction in transaction volumes.
Industrial Belt Reactions: Procurement Decisions Diverge in Keqiao and Shengze
This price signal has triggered different responses in major textile industrial belts. Traders in core chemical fiber fabric hubs such as Keqiao, Shaoxing, and Shengze, Wujiang, typically adjust their quotations rapidly after a sharp oil price drop. According to industry feedback, some polyester plants have suspended daily quotations, waiting for confirmation from night trading sessions. Weaving mills generally adopt a 'produce-to-order' procurement strategy, only replenishing small batches for urgent orders, with little willingness to make large purchases.
It is worth noting that the current period marks the transition from the traditional textile off-season to autumn stockpiling. If oil prices remain low and volatile, the peak procurement season for autumn/winter fabrics in August-September may see a wave of concentrated replenishment. Conversely, if oil prices rebound quickly, this round of cost dividends will be fleeting.
Practical Impact on Buyers and Foreign Trade Enterprises
For buyers, the expectation of cost reduction from the oil price plunge is clear, but risks also exist. First, geopolitical factors could push oil prices higher at any time. Second, polyester plants may cut production to support prices, offsetting the cost reduction. It is recommended that buyers monitor the spread between PTA futures and polyester filament yarn spot prices, and build positions in batches when the spread exceeds 200 RMB/ton.
For foreign trade enterprises, two key points require attention: first, the window for adjusting export quotations is typically only 3-5 days, requiring renegotiation of FOB prices with customers; second, the combined impact of RMB exchange rate fluctuations and lower raw material prices may lead overseas customers to demand even larger price cuts, so a bargaining bottom line should be prepared in advance.
