The transmission of international oil prices and shipping freight rates is now reshaping cost expectations across the textile chemical fiber chain. On August 5, Iran and Oman reached a preliminary agreement on navigation through the Strait of Hormuz, replacing the dual-lane system used for over 60 years with a new temporary route through Iranian territorial waters. Transit efficiency improved by 30%, crude freight rates plunged 22% in a week, and Brent crude fell below $80 per barrel. For the textile industry, this signals a subtle shift in the cost logic of chemical fiber raw materials, but it is far from a trend reversal.
Background
The Strait of Hormuz carries nearly 30% of global seaborne crude oil and 20% of LNG exports, with an average of 130-140 commercial vessels transiting daily under normal conditions. During the recent disruption, daily transits fell to single digits, and even with partial recovery, the number did not exceed 60 vessels. Many tankers were forced to reroute via the Cape of Good Hope, extending transit times and inflating logistics costs across the supply chain. The new temporary route changes the operational framework: the old dual lanes are closed, and all commercial vessels must use the Iranian territorial sea. Detailed rules involve 72-hour advance online reporting, onboard inspections, and tiered transit service fees, forcing shipping companies to adapt to a new scheduling rhythm.
Market reaction was swift: international crude oil fell for a third consecutive session, with WTI settling at $75.22 per barrel and Brent at $79.45, breaking the key $80 threshold. Long positions accumulated on supply disruption concerns were liquidated, and geopolitical risk premiums quickly unwound. However, multiple energy agencies caution that the downside is limited. The new route is only a path plan; full normalization remains uncertain, and a large-scale return of tankers is unlikely in the short term. Additionally, the Red Sea shipping lane continues to face attack risks, and both major energy chokepoints are under pressure, creating a structural gap in global oil supply.
Industry Impact
For the textile chemical fiber chain, lower oil prices directly reduce costs for upstream feedstocks such as naphtha and PX, subsequently affecting PTA, MEG, and polyester filament prices. The spot market has already shown subtle changes: Middle East crude discounts have weakened, some Asian refiners have postponed long-term purchases and increased imports from the Americas and Russia, and downstream petrochemical enterprises have seen a temporary decline in raw material procurement costs. This suggests that the window for chemical fiber plants to procure raw materials may be opening, but the market has not seen large-scale bargain hunting, reflecting lingering concerns about supply stability.
From a logistics perspective, the 30% improvement in transit efficiency is positive for crude shipping, but capacity recovery remains limited. Vessels still rerouting via the Cape of Good Hope cannot return quickly, and global shipping efficiency remains constrained. For textile companies relying on imported raw materials, this means freight costs will decline but not return to pre-crisis levels quickly, and logistics costs will continue to support final product prices. Meanwhile, Asian and European refiners remain heavily dependent on Middle East crude; American, West African, and Russian oil can only serve as supplements, not full replacements for Hormuz volumes. The medium- and long-term supply-demand balance remains tight.
For buyers, the current oil price correction offers a brief bargaining window, but they should be wary of volatility from geopolitical fluctuations. The detailed rules of the new route are not yet finalized, and the磨合 period could introduce fresh uncertainties, with oil prices potentially rebounding on any supply disruption news. Therefore, aggressive shorting of chemical fiber raw materials is not advisable; instead, procurement should be adjusted flexibly based on inventory cycles.
