U.S. officials say a memorandum of understanding tied to an Iran-related peace framework signed by President Donald Trump will make ship transit through the Strait of Hormuz “toll-free.” The officials add that any economic benefits for Iran depend on Tehran meeting its commitments. They also point to a possible $300 billion reconstruction fund for war-battered Iran, saying releases would be “tied to performance.”

At the same time, Iran’s foreign ministry disputes the U.S. wording, saying the arrangement permits Iran to charge maritime service fees for ships transiting the strait, rather than collect “tolls.” The differences center on how fees are characterized under the deal.

Separate reporting says the MoU is brief and sets out a general outline, with more complex issues—particularly Iran’s nuclear program—left for later negotiations. U.S. officials also say Trump, Vice President J.D. Vance, and Iranian parliament speaker Mohammad Bagher Ghalibaf sign the MoU electronically, with Vance set to lead technical talks following the agreement.
