Shipping activity in the Strait of Hormuz is busier than previously reported, with U.S. forces counting nearly 1,000 commercial vessels transiting the waterway over the last two months. This increased activity occurs despite a fragile ceasefire and ongoing military tensions between the U.S. and Iran.
While the volume of ships remains a fraction of the levels seen before the war began on February 28, the new data suggests a higher frequency of transit than earlier estimates indicated.
Why is shipping traffic increasing despite the conflict?
U.S. forces have counted approximately 1,000 commercial vessels entering and exiting the strait during the recent two-month ceasefire period, according to sources told Bloomberg. This averages out to about 17 ships per day, most of which are large container and cargo vessels.
This figure is notably higher than other recent data sets. For instance, the maritime data company Kpler counted 895 ships between March 1 and May 19, while U.S. Navy data from the Joint Maritime Information Center tallied 558 cargo ships and oil tankers between March 1 and June 3.
The higher count of 1,000 ships likely includes vessels using the alternate route along Oman’s coast and those that have turned off their Automatic Identification Systems (AIS) to broadcast their positions.
How is the U.S. military supporting maritime transit?
To bypass the lane established by the Islamic Revolutionary Guard Corps (IRGC)—which has charged tolls and attacked unauthorized ships—the U.S. Navy has worked to re-establish navigation near the coast of Oman. Following mine-clearing operations in April, the military has been helping ships transit via an Omani lane.
According to the Wall Street Journal, the U.S. military uses radar, drones, and other tools to monitor traffic and advise vessels on how to respond to Iranian threats. Central Command has clarified that it is offering advice to commercial vessels rather than providing direct escorts.
Recent activity in the region has remained volatile. Central Command reported that U.S. forces recently shot down Iranian missiles and drones launched toward the strait and neighboring Gulf nations. Additionally, the U.S. conducted “self-defense strikes” in Goruk, Iran, and Qeshm Island following threats to maritime traffic.
Lloyd’s List reported that nearly 40 non-Iranian linked vessels have exited the Gulf in the last three weeks, bringing the total number of once-stranded ships to depart since March to 142. This trend is attributed to “quiet U.S. naval overwatch” and an increased willingness among operators to face the risks.
What are the implications for global energy markets?
The stability of the Strait of Hormuz is critical as global oil markets approach a period of significant volatility. Crude reserves are expected to reach critically low levels in the coming weeks, making the alternate Omani lane increasingly important.
Iran’s control over Hormuz traffic has become a primary source of leverage over the United States. This tension has turned the Persian Gulf into a combat zone, even during the current ceasefire.
Christopher Smart, a former trade adviser and Treasury official in the Obama administration, noted in a New York Times op-ed that the world economy currently relies on the region for 20% of its oil and gas needs. He suggested that if the Gulf’s supplies cannot be delivered, desperate buyers may eventually find new sellers, which could change long-term global dependency on the region.
The continued flow of traffic through both U.S. and Iranian routes may help the global economy adapt to a reality where this chokepoint remains a constant risk.
Frequently Asked Questions
Is the U.S. military providing armed escorts for commercial ships?
No. Central Command has stated that it is not escorting ships, but is instead offering advice and monitoring traffic using radar and drones to assist safe transit.
How does the current ship traffic compare to pre-war levels?
Current traffic is significantly lower than the pre-war rate of more than 100 ships per day, but it is higher than some recent maritime reports suggested.
What role does the IRGC play in the Strait of Hormuz?
The IRGC established its own lane shortly after the war began, charging tolls on permitted ships and attacking those that attempt to cross without authorization.
Will the global economy eventually decouple its energy needs from the Persian Gulf?
