When Brent crude oil touched $100 per barrel for the first time since late July, most textile professionals did not focus on the oil price itself but on a chain of cost curves about to be recalibrated across the polyester industry. On September 9, Brent's intraday gain expanded to 2%, reaching $97.69 per barrel, before quickly breaking through $99 and $100. WTI also strengthened, gaining 2% to $96.14. For an industry where chemical fibers account for over 70% of global fiber production, these numbers mean that the entire price chain—from PX to polyester filament, to grey fabric and finished fabric—is being injected with new upward expectations.
Background
Oil is not a direct raw material for textiles but is the source of the chemical fiber chain. Naphtha is catalytically reformed to produce PX (paraxylene), which then polymerizes with PTA (purified terephthalic acid) to form PET chips, eventually spun into polyester filament or staple. This path determines that for every $1 per barrel change in oil, PX costs move by about $3-5 per ton, while the processing margins for PTA and polyester are quickly squeezed as costs rise.
The timing of this oil surge is noteworthy: September marks the stockpiling window for the traditional peak season. Loom operating rates in Jiangsu and Zhejiang remain high, and polyester plants had just seen sales recover from earlier sluggishness. The last time Brent was above $100, the average market price of polyester FDY 150D stood above 9,000 yuan per ton. Currently, the same product is about 8% lower—meaning that if raw material costs continue to strengthen, there will be a more visible tug-of-war between plants' room to raise prices and downstream affordability.
From the perspective of industrial clusters, chemical fiber traders in Shengze and Changxing have begun to tentatively raise some polyester filament quotes, but the increases are generally limited to 50-100 yuan per ton, far smaller than the theoretical rise in raw material costs. This caution is not due to a lack of willingness to raise prices but rather concerns about the sustainability of terminal orders. After all, rising oil prices push up not only polyester raw materials but also pure benzene and caprolactam on the nylon chain, as well as fuel costs in dyeing and finishing. This multi-pronged pressure makes downstream fabric buyers more inclined to wait than to chase price increases.
Industry Impact
The impact of oil on the textile industry is never uniform. Historical data show that the pass-through from oil to PX typically occurs within 1-2 trading days, while polyester filament price adjustments lag by 3-5 days, and terminal prices for grey and finished fabrics may take 1-2 weeks to digest. This means the market is currently in the "midway" phase of raw material increases: polyester plants' immediate processing profits have been compressed, but downstream has not yet fully accepted new prices.
For buyers, this time lag implies both risk and opportunity. If oil stabilizes above $100 and continues to climb, polyester filament will likely see a catch-up increase of 500-800 yuan per ton. Conversely, if geopolitical tensions ease and oil falls, high-priced inventories will face depreciation pressure. Therefore, judging the persistence of oil price trends is more critical than predicting specific gains. From a fundamental perspective, OPEC+ production cut compliance remains high, and the approaching refinery maintenance season suggests that tight supply will not quickly reverse.
Foreign trade companies need to re-examine their quotation mechanisms. Oil price fluctuations affect export orders through three channels: exchange rates, shipping costs, and raw material costs. If the yuan weakens against the dollar due to higher oil, it may partially offset raw material increases. However, the linked rise in container freight rates and bunker surcharges will directly increase fulfillment costs. For exporters with long-term contracts, it is advisable to include raw material price adjustment clauses or use futures instruments to lock in PTA and polyester costs, avoiding profit erosion from oil spikes.
