WTI crude oil broke through the $70 per barrel mark on July 7, with a daily gain of 1.64%, and Brent crude rose to $72.79 per barrel, also up over 1% intraday. This price level signals tightening cost transmission for the textile chemical fiber supply chain.
The Transmission Chain from Oil to Polyester
Crude oil is the starting point of the polyester chain, directly impacting PX production costs, which then flow to PTA and MEG. PTA accounts for over 70% of the cost of polyester filament yarn and staple fiber. When WTI moves from $69 to $70, a $1 per barrel increase can be amplified to hundreds of yuan per ton in the polyester segment.
China Customs data shows that the average import price of PTA in the first five months of 2026 had already risen by about 8% year-on-year. This oil price breakout will strengthen market expectations for price hikes in PTA and polyester products. For polyester clusters in Shengze, Changxing, and Xiuzhou, raw material procurement timing and inventory management face new challenges.
Cost Pressure and Responses in Industrial Clusters
The direct impact of oil price increases on weaving enterprises is higher raw material procurement costs. In Shengze, with an annual output of over 5 million tons of polyester filament, a 200 yuan per ton rise in PTA means over 1 billion yuan in additional costs annually, excluding the compounding effect of dye and auxiliary price hikes in the dyeing sector.
Large polyester plants typically adjust ex-factory prices 3-5 days after sustained oil price increases. The July 7 breakout may be reflected in POY and FDY quotes within a week. Companies with fast inventory turnover face more immediate pressure, while those with stockpiles have a buffer of about two weeks.
## Price Negotiation in Foreign Trade Orders
The impact of oil prices on textile foreign trade is more complex. On one hand, polyester fabric export quotes may be forced upward, reducing price competitiveness against Southeast Asian suppliers. On the other hand, shipping costs are highly correlated with oil prices, meaning container freight rates may stop declining and start rising.
For foreign trade enterprises focused on polyester fabrics, especially those serving the Middle East and Africa, customers are highly price-sensitive. If raw material costs rise more than 5%, the risk of order diversion increases significantly. However, the current relative stability of the RMB exchange rate provides some room for negotiation.
