Maritime tracking data diverges from US claims on Strait of Hormuz oil shipments
Independent shipping analytics show significantly fewer vessel transits than the volumes asserted by United States officials amid ongoing tensions with Iran.
The short version
- US officials assert that dozens of commercial ships and millions of barrels of oil are moving daily through the Strait of Hormuz under military escort.
- Commercial maritime trackers, including Kpler and Lloyd's List Intelligence, record far fewer transits, observing roughly 11 to 13 vessels per day.
- Iran maintains that it controls the strait and has warned that unapproved vessels risk being attacked or encountering sea mines.
- The discrepancy remains unresolved as analysts cite differences in vessel counting methodologies, convoy manifests, and unverified 'dark' transits with transponders turned off.
Key facts
- US officials and President Donald Trump claimed that roughly 30 to 40 commercial ships carrying millions of barrels of oil have crossed the Strait of Hormuz daily under US military escort.[Al Jazeera]
- US Treasury Secretary Scott Bessent stated that 10 million to 17 million barrels of oil were moving through the waterway per day.[Al Jazeera]
- Marine analytics firm Kpler recorded only 11 transits on Tuesday, five on Monday, and six on Wednesday, with a 10-day daily average of 13 vessels.[Al Jazeera]
- Lloyd's List Intelligence tracked an average of approximately 12 transits daily from August 26 to September 1, noting commercial tracking is limited to cargo vessels over 10,000 deadweight tonnage.[Al Jazeera]
- Iranian Parliament Speaker Mohammad Bagher Ghalibaf asserted that Iranian forces maintain total control of the strait and warned that ships relying on US guarantees would be targeted.[Al Jazeera]
- The Joint Maritime Information Center categorized the risk level in Hormuz as 'severe' on September 1, citing ongoing risks from drifting or uncharted mines despite US de-mining claims.[Al Jazeera]
What remains uncertain
- The exact volume of shipping remains unclear because US figures may include naval auxiliaries, support tugs, or small craft, and many commercial vessels operate 'dark' with transponders deactivated.[Al Jazeera]
- Conflicting claims persist regarding maritime safety and control, with US forces claiming lanes are de-mined while Iran and regional monitors report continued mine strikes and attacks.[Al Jazeera]
