Recent clashes in the Strait of Hormuz, including Iran targeting commercial vessels and subsequent US retaliatory strikes, highlight the ongoing tension surrounding control of the strategic waterway, despite a June 17 memorandum of understanding (MoU) aimed at defusing the conflict. This MoU, requiring Iran to ensure safe passage for 60 days, permits discussions with Oman to define future administration and maritime services in the Strait. However, analysts anticipate continued volatility, with both sides seeking to maximize leverage during negotiations over Iran's nuclear program and the strait's status.

Iran's objective is to exert effective control over the Strait of Hormuz, a position it did not hold before the US and Israel's February attacks. This control is seen as a formidable strategic buffer and a potential new revenue stream, with Iran projecting up to $40 billion annually in transit fees, despite international law treating the strait as an international waterway open to free navigation. Iran is insisting that all ships use its designated routes, close to its shoreline, claiming that transits outside these routes are not guaranteed safe passage by its newly established Persian Gulf Strait Authority. This contrasts with the Omani-led deal with the U.N. International Maritime Organization for a route solely through Omani waters, which Iran objects to.

US officials, including Secretary of State Marco Rubio, have toured the Gulf to reassure Arab monarchies that Washington will not concede to Iran's demands for control of the strait. The US maintains that no country has the right to charge for the use of international waterways. The preliminary agreement has been strained by conflicting assertions, such as Iran's expectation for the release of $6 billion of its frozen assets, which the US insists must be spent exclusively on American goods and for humanitarian purposes. Despite the ongoing issues, U.S. Vice President JD Vance and Iranian Foreign Minister Abbas Araghchi made "encouraging progress" in recent talks in Switzerland, agreeing on a roadmap for a final deal within 60 days, even as threats over other regional conflicts persist.
