WTI crude oil broke through $75 per barrel six hours ago with a daily gain of 5.01%, while Brent crude surged 5.00% to $79.74 per barrel. This spike is not a technical correction but a geopolitical black swan—Iran announced the closure of the Strait of Hormuz, the US struck Iranian targets twice in the early morning, and Trump subsequently declared the restoration of sanctions on Iran. For the textile industry, crude is not fuel but the lifeline of chemical fibers. Oil above $75 per barrel means systematic cost increases for PTA, PX, polyester filament, and polyester staple fiber.
The Strait of Hormuz: What It Means for the Chemical Fiber Chain
The Strait of Hormuz handles approximately 30% of global seaborne crude oil transportation. If the channel is substantially blocked, the global crude supply could face a gap of about 17 million barrels per day. WTI started at $73 and broke through $74 and $75 within 16 hours; Brent's single-day gain of 5% is extremely rare in the past three years. For the textile industry, every $1 rise in crude adds about 80-100 yuan per ton to polyester filament's theoretical cost. At the current $75 benchmark, this single day's surge has already imposed a potential cost pressure of 400-500 yuan per ton on the chemical fiber side.
More critically, this is not a gradual climb but an instantaneous jump. Chemical fiber factories typically maintain 7-15 days of raw material inventory, meaning PTA and MEG procurement quotes will face violent fluctuations in the coming week. Weaving enterprises in polyester clusters such as Shengze, Changxing, and Xiaoshan will see price hike notices from upstream chip and filament suppliers within this week.
Industry Impact: The Transmission Path from Crude to Yarn
The transmission chain—crude -> naphtha -> PX -> PTA -> polyester chip -> polyester filament/staple -> weaving—typically takes 3-5 trading days. The first wave of reaction has already appeared: Asian PX spot quotes jumped about 3.5% on Monday, and PTA futures rose over 2.5% in night trading. If the Middle East situation shows no signs of easing within 48 hours, domestic polyester filament factories are expected to collectively raise ex-factory prices starting Wednesday, likely by 200-400 yuan per ton.
For downstream weaving enterprises, this is a classic cost-push price hike scenario. Unlike demand-pull, cost-push often leaves weavers unable to fully pass on the increase to fabric traders and garment brands. Currently, the water-jet loom utilization rate in Shengze is around 72%, a low level during the off-season, with grey fabric inventory at about 35-40 days. If chemical fiber raw material prices rise by 500 yuan per ton, the cost per meter for weavers will increase by about 0.08-0.12 yuan. Given that the current gross profit on conventional polyester taffeta grey fabric is only 0.15-0.20 yuan per meter, profit margins could be compressed by over 50%.
Traders at Keqiao Textile City reported a noticeable increase in inquiries on Monday, with some testing the waters for stockpiling. However, terminal garment orders have not yet recovered, and domestic demand remains driven by replenishment orders. This wave of stockpiling is more about risk aversion than genuine demand support. If the situation persists for more than a week, the chemical fiber chain could enter a stalemate of 'prices without volume'—upstream raising prices, downstream waiting on the sidelines, and intermediaries squeezed from both sides.
Practical Recommendations
For Buyers - Increase standard polyester filament inventory from 7 days to 14-20 days to hedge against price hikes in the coming week. - Monitor the PTA futures-PX spot spread; if the PX-naphtha spread exceeds $350 per ton, it indicates upstream profit recovery is complete, and downstream price pressure will accelerate. - Avoid chasing long-term monthly contracts at the peak of the rally; prioritize spot small-lot rolling purchases and wait for clarity before locking in quarterly prices.
For Exporters - Shorten export quotation validity from 15 days to 7 days, and add a 'crude oil surcharge clause': if the monthly average WTI price exceeds $75 per barrel, contract prices can be adjusted accordingly. - Monitor RMB exchange rate fluctuations: crude price hikes increase import costs, potentially exacerbating RMB depreciation expectations. Use forward FX settlement to lock in exchange rates. - Communicate raw material cost changes to Middle East and South Asian clients in advance to avoid order cancellations or delays. Textile mills in India and Pakistan also rely on imported PX and MEG, meaning global costs are rising simultaneously.
The sustainability of this crude spike hinges on the restoration of passage through the Strait of Hormuz. If the situation de-escalates within a week, oil could fall back to around $70, and chemical fiber cost pressure will be manageable. However, if the blockade lasts more than 10 days, the average price of polyester filament in Q3 could rise 10%-15% from Q2, substantially eroding weavers' profits.
