Crude oil prices experienced a concentrated sell-off on July 9. WTI crude fell 3.00% intraday, hitting a low of $72.27 per barrel, while Brent crude dropped below $77 per barrel, down 2.48% on the day. For the textile industry, this is not an isolated financial fluctuation but a clear stress test on the cost side of chemical fibers.
Cost Transmission Logic
Crude oil is the absolute source of the polyester chain. From naphtha to PX, then to PTA and MEG, and finally polymerization into polyester chips, filament yarn, and staple fiber—each processing step's spread is amplified during sharp crude oil price swings. WTI's slide from above $74 to the $72 range theoretically opens up room for PTA production cost reductions, but the actual transmission is not synchronized.
The PTA spot market did not immediately follow the decline on July 9, with some plants even reporting flat prices. This is because current PTA social inventories are at moderately low levels, and some unit maintenance has not yet restarted, providing short-term supply support. However, once crude oil weakness is established, PTA processing margins will be compressed, and market sentiment will first be reflected in forward contracts.
The response from the polyester filament yarn sector is more sensitive. Jiangsu and Zhejiang weaving bases are currently in a traditional off-season, with operating rates already declining from June highs. The expectation of lower raw material prices due to the crude oil crash will intensify downstream wait-and-see sentiment—grey fabric traders and apparel brands prefer to digest existing inventories rather than restocking in a downward price channel.
Industrial Belt Reactions
On July 9, the three core polyester production and sales regions—Keqiao, Shengze, and Changxing—all experienced varying degrees of inquiry suspension. A polyester filament yarn plant in Shengze with an annual capacity of 200,000 tons reported a noticeable drop in customer calls in the afternoon, with some already-negotiated orders requiring delayed execution. This 'buy on rising, not on falling' psychology is typical in the polyester industry: when crude oil falls more than 2% in a single day, downstream players often wait for clearer bottom signals.
The export side also felt the chill. Buyers in Southeast Asia and South Asia are highly sensitive to crude oil prices, as polyester fibers account for 30%-40% of their fabric costs. News of WTI breaking $72 was quickly shared in purchasing groups in Bangladesh and Vietnam, with some buyers asking Chinese suppliers to recalculate FOB quotes on the grounds that 'raw material costs have already fallen'.
Inventory and Hedging Strategies
For polyester plants, the most pressing issue is not how much prices have fallen, but how to price existing inventories. Since late June, inventory days for POY, FDY, and DTY have risen to 18-22 days, at mid-to-high levels for the year. If crude oil continues to decline, these inventories will face devaluation risks. Some companies have started selling hedges on futures to lock in processing margins.
For downstream weaving enterprises, the crude oil crash offers a brief purchasing window. However, industry experience shows that a single-day drop of 3% is often not the end—in 2019, 2020, and 2022, similar single-day crashes were followed by further declines of 2%-5% in the following week. Therefore, phased building of positions is more suitable than a one-time bottom-fishing approach at this stage.
Practical Recommendations
For Buyers - Switch the procurement cycle for PTA and polyester filament yarn from 'weekly pricing' to 'daily tracking', focusing on the support level of the $70 mark for WTI. - Sign 'floating price clauses' with suppliers, agreeing to adjust raw material settlement prices based on average crude oil prices to avoid the risk of single-sided locked pricing. - Use futures or forward point pricing to lock in raw material costs for the next 30 days; current basis levels are in a neutral range, making hedging costs controllable.
For Exporters - Re-audit the raw material cost share of existing export orders. For orders primarily using polyester or nylon fabrics, proactively discuss price adjustment mechanisms with customers. - Monitor the linkage between the RMB exchange rate and crude oil prices—crude oil declines often accompany a stronger dollar, which can double-squeeze export profits. - Add a 'raw material price fluctuation clause' to quotations, clearly specifying that when the monthly average WTI crude oil price fluctuates by more than 5%, both parties will renegotiate prices.
Whether this crude oil decline is a short-term correction or a trend reversal remains uncertain. What is certain is that the textile chemical fiber industry has entered a period of high cost-side uncertainty. Whether it is polyester plant inventory management or downstream weaving and export order pricing, crude oil prices must be incorporated as a core variable in daily risk control.
