A cluster of strikes on vessels in the Strait of Hormuz puts a fragile peace framework into jeopardy, as unrestricted passage is a central provision of the newly brokered agreement between the U.S. and Iran.

When Iran attempted to impose transit tolls on ships through the Strait of Hormuz this spring, Secretary of State Marco Rubio dismissed it as illegal: “No country is allowed to charge tolls or fees on an international waterway.

The casket of Iran’s late Supreme Leader Ayatollah Ali Khamenei was carried through the Iranian capital of Tehran for a funeral procession. He was killed in a Feb. 28 airstrike at the beginning of U.S.

The prospect of fees to transit the Strait of Hormuz has sparked alarm, not least by investors who fear it could be replicated in other maritime corridors.
