Sharp Drop in Vessel Transits Through the Strait of Hormuz
At the start of the week, only four commodity vessels were recorded transiting the Strait of Hormuz on Monday, down from ten the previous day, according to preliminary data from the maritime analytics firm Kpler. The following day, Marinelink reported the same four-vessel total, a decline from seven the day before and far below the ten-day average of eighteen ships. The four vessels comprised two dry-bulk carriers (one laden, one in ballast) and two oil tankers in ballast mode. The figures exclude ships that may have disabled their Automatic Identification System transponders.
Background & Context
Before the Iran-initiated war began on February 28, the strait typically handled about 125–140 large commercial vessels per day, representing roughly 20 % of the world’s daily crude oil and liquefied natural gas supply. Since then, escalations—including Houthi missile and drone attacks, Iranian claims of mine-related tanker explosions, and the closure of Saudi Arabia’s east-west oil pipeline after a drone strike—have disrupted normal shipping patterns.
Official Statements & Responses
Iranian Foreign Minister Abbas Araghchi called the forthcoming temporary shipping-lane meeting with Oman an “important event.” Oman’s foreign minister Sayyid Badr Albusaidi said the Gulf meeting was delayed “in the interests of consensus.” Saudi Crown Prince Mohammed bin Salman held urgent discussions with U.S. Central Command chief Admiral Brad Cooper in Jeddah. President Donald Trump announced U.S. assistance for oil-tanker transits and suggested countries might have to pay for naval escorts. The U.S. military and Gulf allies have begun daytime escort operations for tankers, shifting from night-only practice. Iranian news agency Fars, citing the IRGC, reported an oil tanker exploded after colliding with mines in the strait.
Conflicting Reports & Gaps
- Oil-flow figures: The administration’s 17 million bpd claim conflicts with analysts’ estimates of less than half that amount and TankerTracker’s 7.85 million bpd average.
- Vessel routes: Sources agree many recent transits have used Iranian waters, but the exact routes of the four vessels recorded on September 15-16 remain unclear, especially for ships operating with AIS off.
- U.S. stance on lane agreement: While Iran and Oman are preparing a temporary shipping-lane proposal, Washington has not publicly expressed a position.
What’s Next
Iran plans to present the temporary shipping-lane agreement with Oman on an upcoming Monday, aiming to ease the disruption while retaining control over vessel access. Oman is seeking to convene Gulf Cooperation Council foreign ministers in Salalah for further talks, though attendance remains uncertain. The Gulf states have postponed the scheduled meeting with Iran on the strait’s future, and U.S. and Gulf naval forces will continue daytime escort missions with designated transit windows for commercial ships.
