At least 20 oil tankers have traversed the Strait of Hormuz since the U.S. and Iran initiated a de-escalation effort to reopen the vital maritime chokepoint to commercial traffic, according to data from the trade intelligence firm Kpler. While transit volumes remain well below pre-war levels—which saw over 100 daily ship movements—the resumption of traffic marks a significant shift in energy logistics for the Gulf region.
Why does the Strait of Hormuz matter for global oil prices?
The Strait of Hormuz serves as the world’s most critical oil transit chokepoint, with its reopening acting as a primary barometer for global energy market stability. According to Kpler, 25 total vessels, including cargo and container ships, transited the waterway on Thursday. This uptick follows a U.S. Navy decision to end its blockade, coupled with an Iranian policy allowing ships to cross toll-free for a 60-day window. Vice President JD Vance confirmed Thursday that Iranian authorities are currently honoring their commitments regarding the safe passage of commercial vessels.
Super-sized tankers, known as Very Large Crude Carriers (VLCCs), can transport up to 2 million barrels of oil in a single voyage. On Thursday alone, three Saudi Arabian and one United Arab Emirates VLCCs successfully navigated the strait.
How are shipping patterns changing under the new agreement?
Shipping patterns are shifting back toward standard operating procedures as Iranian tankers resume the use of tracking transponders. Matt Smith, commodity research director at Kpler, noted that traffic is currently balanced, with 13 crossings moving West to East and 12 moving East to West. Analysts at Kpler observed five Iranian supertankers departing the region on Friday, a development they described as a sign that the Iranian crude trade is returning to normal patterns after months of operating with vessels “going dark.”
What happens after the 60-day toll-free period?
The long-term governance of the strait remains subject to future negotiations between Iran, Oman, and various Gulf states. Under the current deal terms, the 60-day grace period is intended to stabilize the flow of goods before formal talks on administration begin. Market participants are monitoring these developments closely, as the potential imposition of tolls after this period could alter shipping costs and route preferences for international carriers. Currently, 18 of the observed ships utilized the route designated by Iran, while only one vessel followed the International Maritime Organization (IMO) defined path.
Frequently Asked Questions
Is the Strait of Hormuz fully open to all commercial traffic?
Yes, traffic has resumed following the U.S.-Iran agreement, though volumes have not yet reached the pre-war daily average of over 100 ships, according to Kpler.
Are Iranian tankers participating in the reopened trade?
Yes. Kpler analysts report that Iranian supertankers have begun switching on their transponders again and are actively departing the region with oil shipments.
Will ships have to pay to use the strait?
Not during the initial 60-day period. Future toll structures will be determined through negotiations between Iran, Oman, and Gulf states once the current grace period concludes.
