WTI crude oil futures fell 2.37% in a single session, while Brent dropped 2.81%, settling at $100.05 and $104.61 per barrel respectively. In the context of the chemical fiber supply chain, this is not merely a commodity market move—it directly rewrites the cost anchor for the polyester segment. For industrial belts such as Keqiao, Shengze, and Nantong, which rely heavily on chemical fiber fabrics and home textile exports, softening raw material prices tend to reach quotation sheets faster than order volumes do.
Repricing Along the Cost Transmission Chain
The polyester supply chain is highly dependent on crude oil for pricing. From naphtha to PX, then to PTA and MEG, and finally to polyester filament and staple fiber, the processing spread at each stage is built on a crude oil benchmark. When WTI retreats from above $100 to the $96 range, the night session of PTA futures almost reflexively follows. This means that the next morning, texturing and weaving mills in Shengze and Keqiao will face a lower cost baseline when receiving raw material quotes.
The question is whether this decline is sustainable. The announcement by Yemen's Houthi forces of large-scale military operations against Saudi Arabia briefly pushed oil lower intraday before prices fluctuated. Geopolitical factors mean supply-side uncertainty has not been eliminated, and the downside for oil prices could be compressed by risk events at any time. For chemical fiber plants, the current price softening is more of a window than a trend reversal.
From the perspective of downstream acceptance, profit recovery in the weaving segment takes time. Over the past few months, polyester filament prices have run high, leading many texturing and weaving mills to adopt low-inventory strategies to avoid price depreciation risks. Now that oil prices have fallen, these enterprises have gained bargaining space for restocking. However, whether end customers in apparel and home textiles are willing to accept quotes based on new costs depends on brands' inventory judgments for autumn and winter orders.
Divergent Reactions Across Industrial Belts
Keqiao, as a chemical fiber fabric distribution hub, is most sensitive to raw material price fluctuations. Local traders report that news of falling crude oil typically affects inquiry rhythms within half a day, with buyers postponing orders to wait for clearer price signals. This wait-and-see sentiment also exists in Shengze's grey fabric market, especially for conventional items such as polyester taffeta and pongee, where competition is fierce. For every 100 yuan/ton drop in raw material costs, grey fabric quotes may follow with a 0.05-0.1 yuan/meter decline.
The logic in Nantong's home textile belt is slightly different. Although home textile products are also highly dependent on chemical fiber raw materials, order cycles are longer, and brand customers are less accepting of price adjustments. The cost dividend from falling oil prices is more reflected in factory profits in the short term rather than retail prices. This means Nantong's home textile factories may gain a brief profit recovery period in this round of oil price volatility, but it will be difficult to translate into quotation advantages.
The experience of foreign trade enterprises is more complex. A decline in dollar-denominated crude oil theoretically helps reduce raw material costs for export products, but synchronous fluctuations in the RMB exchange rate may offset some of the dividend. More importantly, European and American buyers react to price changes with a lag. The Spring/Summer 2026 orders currently under negotiation may become the first beneficiaries of the oil price decline.
The Inventory-Order Game
For factories holding chemical fiber raw material inventories, falling oil prices are a double-edged sword. On one hand, lower raw material costs mean new orders can be quoted more competitively; on the other hand, existing inventories face depreciation pressure, especially for enterprises that restocked when oil prices were high. This contradiction is particularly prominent among polyester filament traders, some of whom may choose to cut prices to move goods, further depressing spot prices.
From an order rhythm perspective, falling crude oil may accelerate decision-making among some buyers. Apparel brands that were previously in a wait-and-see mode may seize the opportunity of lower raw material prices to lock in some capacity, especially for cost-sensitive fast fashion orders. However, this window will not last long. Once geopolitical risks push oil prices back up, the cost logic will reverse again.
It is worth noting that processing fees for PTA and MEG are already at low levels, leaving limited room for further compression. This means that even if crude oil continues to fall, the decline in chemical fiber raw materials may be smaller than that of crude oil itself. For textile enterprises, do not simply extrapolate oil price declines linearly to raw material costs—intermediate processing stages will absorb part of the volatility.
