Crude freight rates plunged 22% in a week, and Brent crude fell below the $80 mark, marking the third consecutive session of declines for international oil prices. This price volatility, triggered by shipping route adjustments in the Strait of Hormuz, may seem distant from the textile industry, but it is actually transmitting along the chain of "crude oil—naphtha—PX/PTA—polyester—chemical fiber fabrics." For the petrochemical-based fiber industry, the rapid unwinding of risk premiums may signal a reopening of the feedstock procurement window.
Event Background
On August 5, Iran and Oman reached a preliminary agreement on commercial vessel transit through the Strait of Hormuz, closing the two traditional north-south shipping lanes that had been in use for over 60 years and rerouting all transiting merchant ships to a new temporary route through Iranian territorial waters. Iran's Deputy Foreign Minister Garibabadi confirmed that the agreement is nearly finalized, but detailed rules are still under negotiation, covering 72-hour advance reporting, onboard inspections, and tiered transit service fees. Industry insiders interpret this as a fundamental change in the shipping operation mechanism, not a simple route replacement.
Operational data shows that transit through the strait remains in a "limited recovery" state. Under normal conditions, 130-140 merchant ships pass daily, carrying nearly 30% of global seaborne crude oil and 20% of LNG exports. During the recent disruption, daily transits dropped to single digits, and even with the rebound, they have not exceeded 60 ships. Many tankers are rerouting around the Cape of Good Hope, extending shipping times and raising logistics costs, which constrains a rapid recovery in capacity.
The new route has improved transit efficiency by 30%, releasing pent-up pressure and causing crude freight rates to plummet 22%. However, energy analysts caution that route planning does not equate to normalized operations, and a large-scale return of tankers is unlikely in the short term, leaving Middle East crude export supply unable to recover quickly. Additionally, persistent risks in the Red Sea mean that both key energy chokepoints remain under pressure, creating a structural gap in global seaborne crude supply.
Industry Impact
For the textile industry, the most direct effect of lower oil prices is a phased easing of chemical fiber feedstock costs. PTA and MEG, key polyester raw materials, are derived from naphtha upstream. For every $10 drop in oil prices, polyester production costs fall by approximately 80-100 yuan per ton. With Brent retreating from above $110 to around $79, this theoretically opens up 240-300 yuan per ton of cost space for the polyester chain. However, this transmission has a time lag and depends on changes in PX processing margins.
In the spot market, subtle shifts are emerging: Middle East crude discounts are weakening, and some Asian refineries are postponing long-term procurement plans, temporarily increasing shares of American and Russian crude. This suggests a diversification of naphtha supply sources, which may weaken the cost anchoring role of Middle East crude for Asian polyester feedstocks. For domestic PTA plants, lower feedstock costs help improve processing margins, but they must be wary of oil price rebounds—given the uncertain recovery of Middle East supply and unresolved Red Sea risks, the supply-demand balance remains tight.
For downstream textile enterprises, feedstock price fluctuations directly affect order-taking strategies. Chemical fiber fabric prices are already at low levels; if feedstock costs decline further, fabric quotes may face downward pressure. Conversely, an oil price rebound could squeeze already thin profit margins. Therefore, buyers should not unilaterally bet on sustained low oil prices but should flexibly adjust feedstock inventory levels based on their order cycles.
