On September 1, international oil prices surged 2% in a single day, with WTI breaking above $87 per barrel and Brent approaching $92, up 1.84%. For the textile industry, this is not an isolated commodity move—crude oil is the source cost of the chemical fiber chain, and every $1 per barrel fluctuation cascades through naphtha, PX, PTA, and polyester filament, ultimately reflecting in fabric quotes. When oil jumps 2% in one day, it signals that cost pressures on chemical fibers are shifting from slow accumulation to concentrated release.
Cost Transmission: Time Lag and Amplification
The pass-through from oil prices to chemical fibers is not instantaneous, typically lagging by one to two weeks. But this jump coincides with the quarterly restocking cycle of polyester plants, and spot prices of PTA and MEG have shown signs of following. According to public industry data, POY 150D polyester filament prices rose by about 100-150 yuan per ton in early September compared to late August, while FDY and DTY saw more moderate increases, reflecting different inventory pressures. For weaving mills, higher raw material costs mean increased working capital occupation—if grey fabric order prices do not rise in tandem, profit margins will be squeezed further.
Notably, the amplification effect of oil price rises becomes more pronounced downstream. PTA processing margins are already at multi-year lows, making cost pass-through more elastic; while polyester filament, due to higher capacity concentration, has stronger pricing power. This means fabric buyers may see polyester product quotes rise more than the actual raw material cost increase in the next 2-3 weeks, creating an "overshoot" phenomenon.
Inventory Games and Procurement Rhythm
Another impact of the oil price jump is shifting market expectations. When crude breaks key psychological levels, downstream traders and weaving mills tend to be driven by "buying on rising" sentiment, potentially accelerating restocking. September is traditionally the stocking period for the peak textile season, and cost increase expectations may prompt some enterprises to accelerate raw material purchases, pushing up polyester volume in the short term. However, such concentrated buying can also exhaust future demand, leading to an order gap in the late peak season.
Looking at inventory structures, polyester plants currently hold finished goods inventories of around 15-20 days, a neutral level. If oil prices stay high, plants have incentives to raise prices to pass on costs while controlling operating rates to avoid inventory buildup. For buyers, this means the window for price negotiation is narrowing—with clear cost increase expectations, suppliers' willingness to concede will drop significantly, favoring "fixed volume with floating price" or "market-based" quotes.
Dual Pressure on Export Pricing
For export-oriented textile enterprises, oil price rises also add uncertainty from exchange rate fluctuations. Crude oil is priced in dollars, and oil price changes often correlate with dollar strength, while RMB/USD fluctuations directly impact profit calculations for export orders. If the RMB appreciates simultaneously, exporters face the dual squeeze of higher raw material costs and exchange losses, making price adjustments even more difficult.
From an order cycle perspective, export orders are typically priced 1-2 months in advance, so the current oil jump has limited impact on already-booked orders, but it directly pressures pricing strategies for new orders. It is recommended that exporters include "raw material price linkage clauses" in quotes or adopt short-term validity (e.g., 15 days) to mitigate risks from sharp cost swings. Meanwhile, monitor RMB trends and use forward settlement tools to hedge exchange costs.
