International crude oil prices surged on the evening of June 30, with Brent crude rising over 1% and WTI crude briefly touching $71/barrel. For the textile industry, this is not an isolated commodity event but a core variable directly linked to chemical fiber raw material costs. When oil prices fluctuate by more than 1% in a short period, the pricing logic for downstream products such as PTA, polyester filament, and polyester staple fiber will come under pressure.
The transmission chain from crude oil to textile raw materials is clear: crude oil → naphtha → PX → PTA → polyester filament/staple fiber. Currently, polyester accounts for over 70% of textile raw material usage, especially in mid-to-low-end fabrics and home textiles, where it is almost a rigid demand. Every $1 increase in crude oil per barrel theoretically raises PTA production costs by about 35-40 yuan per ton, and polyester filament costs may rise by 50-60 yuan per ton.
Industry data shows that in the first half of 2026, the correlation coefficient between PTA spot prices and crude oil prices remained above 0.85, meaning most oil price changes are quickly transmitted to the chemical fiber side. If WTI crude holds above $71/barrel, PTA prices are likely to follow upward adjustments.
The impact of this cost change is uneven across textile industrial clusters. In major polyester filament production areas like Shengze, Changxing, and Xiaoshan, inventory levels and order cycles directly determine pricing power. Currently, most chemical fiber factories have inventory days of 12-15 days, a moderately low level that supports upstream price increases. However, for downstream weaving enterprises, especially those in the Keqiao market relying on spot orders, sudden raw material cost increases mean rapid profit margin compression.
Notably, this oil price fluctuation occurs at the end of June, a transition period between the traditional off-season and autumn/winter fabric preparation. Some weaving factories have started stocking for second-half orders. If raw material prices continue to rise, they may delay procurement or switch to lower-cost alternatives like recycled polyester or viscose.
For foreign trade enterprises, the impact of oil price volatility is more complex. On one hand, higher chemical fiber costs will raise FOB quotes for export fabrics, weakening China's price competitiveness in Southeast Asian markets. On the other hand, if oil price increases signal global demand recovery, it could boost terminal garment orders, creating a volume-price growth scenario. The key is the sustainability of this rally.
Historically, WTI crude in the $70-75/barrel range is considered 'moderately high' by the industry, and chemical fiber companies can usually absorb costs through small price increases. But if oil prices break $75 and sustain, it may trigger downstream resistance, leading to lower polyester filament sales rates and a 'price without volume' deadlock.
