U.S. Secretary of State Marco Rubio Warns Against Toll Charges in the Strait of Hormuz
6/24/2026, 1:56:56 AM
Background & Context
In late June 2026 the United States and Iran signed a memorandum of understanding (MoU) in Switzerland that pledged an immediate cease-fire, a 60-day waiver on tolls in the Strait of Hormuz, and a framework for nuclear inspections. The agreement followed a two-day diplomatic push led by U.S. Vice President JD Vance and was intended to reopen the strategic waterway that carries roughly one-fifth of global oil shipments.
Core Event: Rubio’s Public Declaration on Toll-Free Transit
On 24 June 2026, Secretary of State Marco Rubio arrived in Abu Dhabi, United Arab Emirates, the first stop of a three-nation Gulf tour. In remarks to reporters he asserted that no nation may impose fees on the strait, emphasizing that “it’s an international waterway” and that the United States would not accept any toll-imposing scheme.
Data & Statistics
- The MoU includes a 60-day prohibition on tolls, expiring on 21 August 2026.
- Iran has discussed levying “fees for unspecified services,” a proposal the U.S. deems a toll.
- The International Maritime Organization (IMO) plans to evacuate more than 11,000 stranded seafarers.
- Since the strait’s reopening, 172 vessels have transited, including 42 ships on a single Saturday, far below the pre-conflict average of about 138 daily crossings.
- Oil prices spiked above $100 per barrel after the February 2026 closure.
Official Statements & Responses
Rubio told Gulf journalists that the United States will enforce existing international law prohibiting tolls. IMO Secretary-General Arsenio Domínguez described the evacuation plan as “a decisive step towards restoring maritime security.” Iranian foreign-ministry spokesperson Esmail Baghaei warned that Tehran would not abandon negotiations on the strait’s administration.
Criticism & Opposition
Iranian officials argue that the proposed charges are “fees for services” rather than tolls, contending that the MoU’s 60-day waiver does not preclude future arrangements. The Iranian side also stresses its right to manage the strait jointly with Oman, a claim not addressed in Rubio’s statements.
Conflicting Reports & Gaps
Sources differ on the MoU’s long-term provisions: some reports say the agreement merely pauses tolls for 60 days, while others suggest it leaves open the possibility of a permanent fee regime after that period. Additionally, the exact nature of the “fees” Iran intends to levy remains undefined, creating uncertainty for shipping operators.

- “No country is allowed to charge tolls or fees on an international waterway. That's existing international law. That's the way it is.” — Marco Rubio, U.S. Secretary of State (NY Times)
- “I think all the countries in this region would agree with us.” — Marco Rubio (PBS)
- “a decisive step towards restoring maritime security and bringing to an end the unacceptable attacks against civilian shipping” — Arsenio Domínguez, IMO Secretary-General (BBC)
- “We will definitely not abandon this issue. We will both document and demand,” — Esmail Baghaei, Iranian Foreign-Ministry Spokesperson (The Guardian)
- “The MOU states that the US, Iran and “their allies in the current war” declare the “immediate and permanent termination of military operations on all fronts, including in Lebanon” – a formulation that clearly gives the impression of trying to bind Israel to an end to operations against Hezbollah.” — Memorandum of Understanding (The Guardian)
Why It Matters
The strait’s freedom is critical to global energy markets; any fee regime could raise shipping costs, disrupt oil flows, and trigger price volatility. Maintaining a toll-free corridor also underpins regional security arrangements and the credibility of the U.S.–Iran cease-fire framework.
What’s Next
Rubio will meet leaders in Kuwait and Bahrain before a Gulf Cooperation Council summit, where the 60-day waiver’s expiration will be a focal point. Parallel talks between Iran and Oman aim to draft a long-term administration model for the strait, while the United States prepares to enforce the toll-free provision through diplomatic and, if necessary, naval channels.
