On July 17, international crude oil markets experienced sharp volatility, with Brent crude rebounding from below $83 per barrel to $85.81 in less than 12 hours, posting a daily gain of over 2%. WTI crude followed suit, climbing 2.53% to hit $81.47 per barrel. For the textile chemical fiber supply chain, such intraday swings signal a rapid reshaping of raw material cost expectations.
How Crude Volatility Transmits to Chemical Fibers
Brent crude dipped below $83 at 14:04, then recovered to $84.96 by 19:11 and touched $85.81 at 21:52. WTI's trajectory was even steeper: from an intraday low of $78.66 (down over 1%) to a high of $81.47. This V-shaped reversal reflects multiple factors—geopolitical tensions, OPEC+ production cut expectations, and market bets on Fed policy shifts.
For the textile industry, crude oil prices are the anchor for chemical fiber raw material pricing. PTA and MEG are directly driven by naphtha and PX prices, and crude accounts for over 60% of the cost of polyester filament yarn and staple fiber. When Brent moves from below $83 to above $85 in a single day, PTA spot market pricing logic shifts immediately—suppliers tend to withhold offers or raise quotes, while downstream mills face the difficult choice of whether to chase prices.
Cost Squeeze on Downstream Weaving Mills
The current period is traditionally a slack season for textiles. Loom operating rates in Jiangsu and Zhejiang are generally between 60% and 70%, with gray fabric inventories at relatively high levels. In this supply-demand context, a sudden raw material price hike puts dual pressure on weaving mills: profit margins on existing orders are quickly compressed, and price negotiations for new orders become extremely difficult.
Historical data show that a single-day crude oil gain of over 2% typically transmits to polyester filament yarn quotes within 2-3 trading days, with increases ranging from CNY 100 to 300 per ton. However, the current volatility is unique—it occurs during a window where global demand is weak but supply-side tightening expectations persist. Chemical fiber producers want to raise prices to restore margins, but fear that excessive hikes could lead to downstream mill shutdowns in protest.
Key Variables in the Supply Chain Game
Three variables will determine the outcome. First, crude's follow-through: if Brent holds above $85 and breaks $87, the chemical fiber price hike becomes irreversible; if it's just a temporary spike, polyester plants' price increases may remain tentative.
Second, PTA inventory levels. Current social inventory is moderately low, and some major plants have slowed contract deliveries, providing a basis for price increases. However, downstream polyester mills also hold decent feedstock inventories, giving them a buffer to observe market direction.
Third, the recovery of end-user orders. Export orders showed marginal improvement at the end of Q2, but domestic demand remains subdued due to weak consumer confidence. If cost increases cannot be passed downstream, margin erosion at the weaving stage will be inevitable.
