Crude freight rates plunged 22% in a week, and Brent fell below $80. The adjustment of transit rules in the Strait of Hormuz is now transmitting down the supply chain. For the textile industry, this is not a simple oil price fluctuation but the starting point for repricing chemical fiber feedstock costs. Polyester and nylon rely heavily on petrochemicals, and changes in oil prices and shipping costs directly affect the price expectations of intermediates such as PTA, ethylene glycol, and caprolactam.
Event Background
On August 5, Iran and Oman reached a preliminary agreement on commercial vessel transit through the Strait of Hormuz. The two traditional shipping lanes, used for over 60 years, are closed, and all transiting ships will use a new temporary route through Iranian territorial waters. Industry data shows that under normal conditions, the strait sees 130-140 commercial vessels daily, carrying nearly 30% of global seaborne crude oil and 20% of LNG exports. During the recent disruption, daily transits fell to single digits, and even with partial recovery, they have not exceeded 60 vessels. Many tankers are rerouting via the Cape of Good Hope, extending transit times and raising logistics costs.
The new route's core rules involve 72-hour advance online reporting, onboard inspections, and tiered transit service fees, with final details pending. Regional maritime service providers indicate that scheduling processes, inspection cycles, and fee structures are all being updated, requiring shipping companies to overhaul operations. This means capacity recovery will take time even after the route opens, and short-term logistics bottlenecks remain.
Industry Impact
For the chemical fiber supply chain, lower oil prices directly reduce feedstock costs. Brent has fallen from over $110 to $79.45, and Middle Eastern crude discounts have narrowed. Asian refiners have turned cautious, with some delaying long-term purchases and increasing American and Russian supply. Spot market activity has cooled, and refinery input costs have dropped temporarily, but no large-scale bargain hunting has occurred—reflecting lingering concerns about supply stability.
This caution translates to the textile raw material market, where PTA and polyester filament prices face downward pressure, but the downside may be limited. On one hand, the 30% improvement in strait transit efficiency has released some backlogged capacity, and the plunge in freight rates helps lower landed costs of imported feedstocks. On the other hand, Red Sea shipping risks persist, and both major energy chokepoints are under strain, so Middle Eastern crude exports cannot recover quickly, keeping the global supply-demand balance tight.
For domestic textile companies, feedstock cost fluctuations directly affect profit margins. Chemical fibers account for over 60% of textile raw material costs; every $10 drop in oil prices reduces polyester production costs by approximately 400-500 yuan per ton. However, if geopolitical risks resurface, prices can rebound just as quickly. Therefore, it is unwise to chase the downside aggressively; instead, focus on actual supply-demand fundamentals.
