Escalating US-Iran Tensions | Restrictions on the Strait of Hormuz May Trigger Sharp Rises in Sea & Air Freight Rates

eopolitical frictions between the United States and Iran keep intensifying. The market widely worries that the situation may further deteriorate and even lead to direct military conflict. Once the US launches military strikes against Iran, the Strait of Hormuz — the world’s vital shipping artery — will face immediate risks. A domino effect will disrupt sea freight, air freight and energy prices. All foreign trade factories and cross-border e-commerce businesses trading with the Middle East, Europe and Asia will be directly affected. Combining the latest global shipping market updates, Friday International Logistics (Guangzhou) Co., Ltd. sorts out potential impacts and practical countermeasures.

The Strait of Hormuz serves as the sole maritime exit of the Persian Gulf. Around 20% of global crude oil and massive volumes of LNG pass through this waterway. It is also the primary route for container vessels travelling to and from the Persian Gulf nations.

In the event of conflict, Iran may impose countermeasures targeting shipping lanes:

1. Passage through the strait will be restricted; major carriers may suspend booking services for Persian Gulf routes out of safety concerns.
2. Numerous merchant vessels will divert from standard routes and sail around the Cape of Good Hope in Africa.
3. Detours add 3,000–4,000 nautical miles to voyages, extending transit time by 10–14 days. The risks of port congestion and cargo detention will surge dramatically.

Disruptions will not be limited to shipments bound for Iran. Vessels heading to UAE, Saudi Arabia, Qatar, Kuwait and other Gulf nations will also be impacted by market risk aversion.

In previous periods of heightened tensions in the Middle East, leading shipping lines temporarily suspended bookings for Persian Gulf services and adjusted port call schedules. Route diversions reduce vessel turnover, shrink available capacity in the market and push container ocean freight rates notably higher. Meanwhile, congestion at transit hubs will lead to increased container detention charges, demurrage fees and terminal surcharges, further lifting overall logistics costs for cargo owners.

Expectations of conflict will drive up international crude oil prices. Bunker fuel and aviation fuel costs will rise simultaneously. Carriers will gradually increase base freight rates for sea, air and land transport, passing higher expenses along the whole supply chain.

Marine underwriters will reclassify sea areas as high-risk zones, raise additional war risk premiums, and may stop offering coverage for certain regions in severe cases. Shippers will either bear steep insurance surcharges or face insufficient cargo protection. Compensation will be difficult to obtain if vessels come under attack or detention.

Deteriorating airspace security over the Persian Gulf will prompt airlines to alter flight paths to avoid high-risk zones. Flights to the Middle East will be cut, space on air services will tighten, direct flights may switch to transit connections, air transit times will lengthen, and air express rates will climb.

1. Risk of delayed delivery: Route diversions, port inspections and temporary suspended sailings easily cause missed delivery deadlines, triggering customer claims and order breaches.
2. Squeezed profit margins: Higher freight and insurance fees erode order profits if additional logistics costs cannot be shared with overseas buyers.
3. Cargo detention risks: Cargo at sea or waiting for loading may remain at anchor for long periods, accumulating continuous extra charges.
4. Passive market conditions: Many companies may postpone shipments to the Middle East; overseas purchasers may delay placing orders and disrupt regular trade schedules.

1. Hierarchical order planning Prioritise air freight solutions for high-value, time-sensitive goods. Reserve sufficient transit cycles for low-value bulk commodities to avoid tight delivery deadlines.
2. Diversify logistics routes Avoid over-reliance on sea freight via the Persian Gulf. Evaluate multimodal transport and transshipment options via Oman in advance. Consult freight forwarders to prepare alternative channels and reduce reliance on a single shipping lane.
3. Add risk clauses to sales contracts Include terms covering geopolitical conflicts and shipping lane disruptions in new contracts. Agree on negotiation mechanisms for delayed shipments and extra logistics expenses.
4. Arrange comprehensive cargo insurance Confirm war risk coverage before shipment and avoid skipping insurance to guard against potential losses.
5. Lock in space and quotations early Freight rates fluctuate rapidly amid geopolitical uncertainty. Secure quotations and confirm channels as soon as possible if you have upcoming shipments; delays often lead to sudden cost increases.

Geopolitical conflicts represent typical black swan events with highly unpredictable outcomes. Nevertheless, forward risk assessment can minimise losses caused by supply chain turbulence.
