On July 21, international crude oil prices staged a concentrated intraday rally. WTI crude expanded from a 1% gain to 3% within hours, closing at $85.40/barrel. Brent crude followed suit, rising over 2% to settle at $89.4/barrel. For the polyester industry chain, this is not a fluctuation to be ignored.
Cost Transmission: How Short Is the Chain from Oil to Chemical Fiber?
From crude oil to textile chemical fibers, the chain passes through naphtha, PX, PTA, and MEG. For PTA, its price correlation coefficient with Brent crude has long remained above 0.85. When oil spikes 3% in a day, PTA production costs theoretically rise by about 2%-2.5%. Industry public data show that current PTA processing margins are already at mid-to-low levels over the past 12 months, making plants highly sensitive to raw material cost fluctuations.
Polyester filament yarn and staple fiber are directly driven by PTA and MEG costs. If crude holds at current levels, quotes for polyester POY, FDY, and DTY will likely follow upward within the next two weeks. For integrated companies with captive polyester capacity, this volatility may even amplify their cost advantage. For weaving mills relying on external purchases, the pressure on procurement costs will be more direct.
Industrial Cluster Response: Keqiao and Shengze May Adjust Sourcing Pace
The China Textile City—Keqiao in Shaoxing and Shengze in Wujiang—is the world's largest polyester fabric trading hub. Weaving mills there typically begin stocking for autumn/winter fabrics in mid-to-late July, right in the procurement window. The crude oil anomaly means polyester suppliers may quickly revise quotes upward, leaving mills caught between the fear of chasing highs and the risk of missing lower prices.
Historical patterns show that after a single-day crude gain exceeding 2%, polyester plants often issue price hike notices the next day or the day after. This means intermediaries and fabric buyers in Keqiao and Shengze need to rapidly reassess inventory costs, and spot markets may briefly pause for observation. For mills holding unfulfilled orders, whether raw material cost increases can be passed downstream depends on whether the order contract includes a price adjustment mechanism.
Q3 Outlook: Profit Redistribution Along the Polyester Chain
This oil price surge is not an isolated event. Over the past three weeks, Brent crude has rallied from the $82/barrel range to $89/barrel, a cumulative gain of over 8%. Driving factors include improved OPEC+ compliance, incremental demand from the North American summer driving season, and geopolitical risk premiums.
For the textile industry, what matters more is the profit shift within the polyester segment. Current spreads between polyester filament yarn and finished fabrics are at historically mid-to-low levels. If crude continues to rise while downstream apparel brands resist fabric price hikes due to weak end-consumer demand, profits will concentrate upstream in raw materials, squeezing weaving and dyeing margins to near breakeven.
