International crude oil prices have retreated by over 20% in a single week, with Brent falling below the $80 mark, while transit efficiency through the Strait of Hormuz has improved by 30%—this seemingly contradictory data combination is reshaping cost expectations for the global textile raw material supply chain. For chemical fiber and polyester industries, crude oil is not just an energy source but the starting point for core raw materials such as PTA and polyester filament. A drop in oil prices means a phased relief of raw material cost pressure, but the complete restructuring of the strait's shipping mechanism casts a shadow over supply chain stability.
Event Background
On August 5, Iran disclosed a preliminary agreement with Oman on commercial shipping through the Strait of Hormuz, closing the dual-lane system used for over 60 years and rerouting all merchant vessels through a new temporary route via Iranian territorial waters. According to regional maritime service providers, detailed rules for the new route are still under negotiation, involving 72-hour advance online reporting, onboard inspection, and tiered transit service fees. This breaks the mature navigation, reporting, and scheduling rhythm, forcing shipping companies to restructure their operational processes.
Actual operations show transit volumes remain far below normal. The strait typically sees 130-140 commercial vessels daily, carrying nearly 30% of seaborne crude oil and 20% of LNG exports; currently, daily transits have not exceeded 60 vessels. Many tankers are rerouting around the Cape of Good Hope, extending shipping times and raising logistics costs across the chain. This explains why a 30% efficiency improvement coexists with a 22% freight rate plunge—efficiency gains are limited to the new route itself, while overall capacity recovery is constrained by rule adjustments and detour inertia.
For the textile industry, the core impact lies in the dual changes of raw material costs and logistics lead times. Lower crude prices directly reduce procurement costs for basic feedstocks like naphtha and PX, theoretically opening room for price reductions in polyester and nylon products; however, longer transit times due to detours may delay arrivals of Middle Eastern cargo, disrupting inventory planning for downstream mills.
Industry Impact
The rapid unwinding of geopolitical risk premiums is a double-edged sword for textile raw material markets. On one hand, Brent's retreat from above $110 to $79.45 weakens cost support for chemical fiber feedstocks, potentially triggering a price adjustment across the polyester chain. According to public industry data, Asian refiners have slowed medium-term crude purchases from the Middle East, shifting toward American and Russian supplies, which will gradually transmit to spot prices for naphtha and PX.
On the other hand, long-term uncertainty about strait transit persists. New route details have not been finalized, and provisions such as vessel inspections and tiered service fees may affect actual efficiency. Red Sea shipping risks remain, with both global energy chokepoints under pressure, making it difficult to quickly restore Middle Eastern crude export capacity. For Asian textile chemical fiber companies reliant on Middle Eastern naphtha, this implies a structural supply gap may persist, and price volatility risks are not truly resolved.
For buyers, this is a window to reassess raw material inventory strategies. Cost benefits from lower oil prices may be offset by logistics delays, and simply chasing low spot prices could face arrival uncertainties. For chemical fiber plants, lower raw material costs help improve margins in the short term, but they should be wary of potential upstream PX supply tightness—if strait transit remains below normal, reduced Middle Eastern supply could raise substitute prices and erode cost advantages.
