The Strait of Hormuz has a map of proposed transit routes and, as of 17 August 2026, no agreement on what to do with it.
Iran announced on that date that it had reached a broad understanding with Oman on the coordinates of shipping lanes through the strait — the narrow waterway connecting the Persian Gulf to the wider ocean and the passage through which, before the war, roughly one-fifth of the world's traded oil moved. Iranian Foreign Ministry spokesperson Esmail Baghaei confirmed that "an understanding has been reached regarding the map of the transit route" but acknowledged that talks had proceeded slowly and that a joint statement had not yet been finalised.
The same day marked the expiry of the 60-day negotiating window established under a June 2026 memorandum of understanding (MoU) between the United States and Iran. No agreement was announced and no extension confirmed, leaving the arrangement in a state of deliberate ambiguity that has suited neither side.
The strait was closed after U.S. and Israeli strikes on Iran on 28 February 2026. The MoU that followed committed Iran to "safe passage of commercial vessels with no charge for 60 days only" and tasked Iran and Oman with defining future maritime administration — language Tehran now interprets as authorising an entirely new control regime, and Washington does not.
The proposed framework, as described by Iranian Deputy Foreign Minister Kazem Gharibabadi, would route commercial ships through Iranian territorial waters on both the inbound and outbound legs of their journey. A joint Iran-Oman coordination centre would manage traffic and gather information from vessels, according to CNN. During an initial interim period, ships would transit without fees. Beyond that, the positions diverge sharply: Iran is seeking transit fees of five to seven percent of cargo value, Oman has discussed fees of around three percent, and Washington insists on zero, according to Reuters.
The physical state of the waterway complicates any timetable. An estimated 70 to 100 explosive devices remain planted in the strait, according to the Times of Israel, and the proposed deal includes a dedicated 30-day mine-clearing phase. Whether that window is realistic is unknown.
Iran has also set political conditions before any reopening takes effect. Tehran is demanding that Washington end its naval blockade on Iranian ports, reverse reimposed sanctions — particularly on oil — resume negotiations over frozen Iranian assets, and ensure stability in Lebanon, as set out in the MoU, according to CNN. U.S. officials have repeatedly stated they will not accept Iranian control over the strait and insist on a return to pre-war, freely open navigation, as Reuters has reported.
In the meantime, U.S. forces have been operating in the strait. United States Central Command (CENTCOM) stated that since early May 2026, American forces helped facilitate the transit of more than 800 commercial vessels and 380 million barrels of crude oil through the waterway, according to Al Jazeera.
Meanwhile, Iran has been repositioning internally. On 9 and 10 August 2026, Supreme Leader Mojtaba Khamenei oversaw a sweeping restructuring of Iran's senior security and military leadership, including the appointment of Mohsen Rezaei as secretary of the Supreme National Security Council (SNSC) and new commanders across the Islamic Revolutionary Guard Corps (IRGC), the General Staff, the IRGC Navy, and the Basij, according to Daily Sabah. Analysts read the changes as a signal of maximum deterrence rather than concession.
What remains unresolved is the central question both sides have avoided answering directly: whether any arrangement that gives Iran a formal role in administering the strait is one Washington will ever accept. The gap between route coordinates and a workable agreement remains wide.
