The shipping rules in the Strait of Hormuz are undergoing their biggest adjustment in sixty years, with tanker rates plunging 22% in a single week and Brent crude falling below the $80 mark. This chain reaction stems from a new shipping agreement between Iran and Oman: the two traditional north-south lanes, used for over 60 years, are closed, and commercial vessels are rerouted to a single temporary route passing through Iranian territorial waters. For the textile and chemical fiber industry, energy and logistics cost fluctuations are being transmitted along the supply chain to raw materials such as PTA and polyester filament.
Background
On August 5, Iran's deputy foreign minister confirmed that the Iran-Oman shipping agreement is nearing finalization, with the core plan being the closure of the two traditional lanes and the activation of a new temporary route, mainly through Iranian waters with a small portion near Oman. Maritime agencies note that the old dual-lane system was mature, with fixed separation standards for tankers, LNG carriers, and chemical ships, ensuring stable scheduling efficiency. The new route requires shipping companies to overhaul operations, including reporting procedures, inspection cycles, and vessel checks.
Regional maritime service providers reveal that supporting rules for the new route are still under discussion, focusing on three aspects: 72-hour advance online reporting, onboard verification, and tiered transit service fees. Official details will be released with the agreement. Currently, transit volumes remain far below normal, with daily vessel numbers recovering from single digits but not exceeding 60, compared to the normal 130-140 vessels per day, which carry nearly 30% of global seaborne crude oil and 20% of LNG exports.
Industry Impact
The route adjustment directly absorbed geopolitical risk premiums, with crude oil falling for three consecutive days, WTI at $75.22 per barrel and Brent at $79.45, breaking the $80 threshold. Previously, Brent had surged above $110 due to supply disruption fears. The new consensus led to expectations of a stable passage, prompting long positions to exit. However, analysts warn that deep price declines are limited: normalization of transit remains uncertain, Red Sea risks persist, and Asian and European refiners' high dependence on Middle Eastern crude means US, Russian, and West African oil can only supplement, not replace.
For textile upstream sectors, crude oil prices directly affect the costs of PTA, MEG, and other chemical fiber raw materials. The oil price drop implies a temporary reduction in chemical fiber production costs, but the plunge in freight rates is accompanied by extended transit times and high logistics costs due to rerouting via the Cape of Good Hope, which has not been fully resolved. In the spot market, Middle Eastern crude discounts have weakened, Asian refiners are postponing purchases, increasing shares of American and Russian crude, and downstream petrochemical companies see lower procurement costs but are not hoarding.
The new route boosts transit efficiency by 30%, easing congestion, but the shipping market remains in a "limited recovery." For textile trading companies, improved energy transport efficiency may reduce freight surcharges, but the habitual rerouting via the Cape and associated cost volatility remain.
