U.S. Secretary of State Marco Rubio has formally rejected Iran’s proposal to impose transit tariffs on the Strait of Hormuz, labeling the waterway an international passage where no nation holds the right to levy fees. This diplomatic clash follows a preliminary peace agreement between Washington and Tehran, which includes a 60-day negotiation period to address sanctions, nuclear programs, and maritime security.
Why the U.S. Opposes Iranian Transit Tariffs
The United States maintains that the Strait of Hormuz is an international waterway, not a toll road. According to Secretary of State Marco Rubio, speaking during a regional tour in the United Arab Emirates, no country has the legal authority to charge fees for passage through this critical transit point. Rubio stated on June 24, 2026, that he expects regional consensus on this position, as reported by AFP.
This stance directly counters recent statements from Iranian officials, including negotiator Mohammad Bagher Ghalibaf, who suggested the strait’s post-war status would differ from the pre-war norm. Iran and Oman, which share coastal access to the strait, announced on June 23, 2026, that they are studying the administration of the route and potential service fees while maintaining claims of national sovereignty.
The Strait of Hormuz is one of the world’s most significant “chokepoints,” with approximately one-fifth of global oil consumption passing through its narrow waters daily.
Impact on Global Shipping and Oil Markets
The recent blockade of the strait caused significant volatility in global oil prices. According to maritime tracking platforms, traffic through the strait reached its highest level since the onset of the conflict on June 22, 2026. Despite this recovery, current shipping volume remains at roughly 40 percent of pre-war capacity, or approximately 120 vessels per day.
The United Nations has intervened to address the humanitarian impact of the previous blockade. The UN maritime body confirmed it is coordinating with Iran, Oman, and the U.S. to facilitate the evacuation of over 11,000 stranded sailors. These operations are contingent upon receiving formal safety guarantees from all parties involved in the regional conflict.
What Happens Next in the 60-Day Negotiation?
The current 60-day window, following initial talks in Switzerland, serves as the primary diplomatic venue for resolving maritime rights. While Washington and Tehran have agreed to establish communication channels to keep the strait open, the dispute over “sovereignty” versus “international waters” remains the central friction point.
Pro Tip: Monitor updates from the International Maritime Organization (IMO) regarding the status of the 11,000 stranded mariners, as this serves as a key indicator of whether the peace agreement is holding on the ground.
