Hormuz Strait Shipping Routes Diverge Amid Heightened Tensions
Date: June 12, 2026
Introduction
The Strait of Hormuz, a vital passage for global energy, is experiencing significant shifts in commercial shipping patterns due to rising geopolitical tensions. Mariners are increasingly opting for alternative routes, particularly one that runs close to the coast of Oman. While this route helps maintain the flow of crude oil, navigation experts caution about the heightened risks, especially the likelihood of collisions.
Increased Utilization of High-Risk Maritime Route
Recent reports indicate that a maritime route near Oman is seeing more traffic, with around 15 vessels, mainly oil tankers, using it daily under US aerial protection. This shift follows directives from former US President Donald Trump to conduct covert operations to safeguard oil tankers in the Strait of Hormuz, facilitating the passage of about 200 commercial vessels and allowing 100 million barrels of crude oil to reach international markets.
Shipping Volume and Safety Concerns
Experts, including Dan Smoot, CEO of Vantor, highlight that shipping activity through the Strait of Hormuz is substantial, exceeding expectations despite limited media coverage. However, shipping companies remain cautious about security risks. John Stawpert from the International Chamber of Shipping warns that the new route is narrow, restricting maneuverability and increasing navigation hazards. The practice of 'blind flying,' where vessels turn off GPS signals to evade detection by Iranian forces, is also on the rise, contributing to suppressed oil prices below $100 per barrel.
Impact of Disruption on Global Supplies
Consultancy Energy Aspects estimates that disruptions in the strait have cut global oil supply by about 12 million barrels per day, equivalent to the capacity of six supertankers. Iraq, Kuwait, and the UAE are currently moving around 3 million barrels of crude oil daily through the strait. Notably, Kuwait's Al-Ahmadi port inventory saw a reduction of nearly 8 million barrels by the end of May, indicating increased loading activities. Amrita Sen from Energy Aspects noted that 'blind flying' allows refineries to increase output, potentially avoiding summer supply tightness. However, current transit volumes remain significantly lower than pre-conflict levels, where around 135 ships passed daily.
Escort Mechanisms and New Shipping Models
Aerial Coordination and US Support
The US has established a coordination mechanism to provide aerial support for vessels using the Omani route. Ships must seek permission from US Central Command and are given specific route coordinates while being advised to disable GPS and navigate at night.
Risks of the Omani Route
A tanker executive described the Omani route as a challenging "on-ramp, two-way street," where laden vessels struggle to maneuver, likening it to "driving on a country road at night without lights," which significantly raises accident risks.
Mutual Security Escalation
The security situation is tense, with reports of an Apache helicopter being struck by an Iranian drone during an escort mission, leading to US retaliatory strikes. The US Central Command characterized these actions as a response to attacks on US forces and international vessels.
Innovative Solutions Amidst Challenges
Increased At-Sea Transshipment
Despite ongoing tensions, the Omani route has enabled increased crude oil exports from the Gulf. At-sea transshipment activities, where cargo is exchanged between vessels, have surged, with radar satellite imagery revealing multiple ship-to-ship transfers occurring off Fujairah.
Risk-Sharing Model in Shipping
The Omani route, which narrows to about 800 meters in some areas, poses significant challenges for large vessels. The US allows two-way traffic but requires vessels to meet in wider waters. Shipping data indicates that tankers are increasingly shuttling between Gulf loading terminals and offshore transfer points, with this method accounting for 80% of non-Iranian oil exports. In early June, crude oil exports via this method reached approximately 2 million barrels per day, nearly double the levels seen in May.
Alternative Routes within Territorial Waters
Shipowners believe that the main shipping lane in the Strait of Hormuz has been mined by Iran, forcing vessels to reroute either south via the Omani route or north through Iranian waterways. Data shows a significant increase in vessels using the northern corridor, although this route requires approval from Iran's Islamic Revolutionary Guard Corps.
Efforts to Curtail Iranian Exports
The US has been working to limit Iran's oil exports since mid-April, with estimates indicating that around 500 commercial vessels remain stranded in Gulf waters, down from 800 at the conflict's onset.
Conclusion
In light of these complex circumstances, the maritime shipping industry is adapting to increasing challenges. While alternative routes provide temporary solutions, the ongoing risks and escalating tensions highlight the need for long-term strategic resolutions to ensure the stability of global energy flows and the security of essential maritime passages.
