Iran and Oman Reach Preliminary Agreement on Temporary Strait of Hormuz Shipping Corridor with Revenue Sharing

BLUFIran is very unlikely to declare the Strait of Hormuz open before November, using corridor access as leverage while US sanctions relief remains undelivered.

Iranian Deputy Foreign Minister Kazem Gharibabadi said Iran and Oman agreed on a temporary shipping route through the Strait of Hormuz, with the corridor's entry and part of its exit running through Iranian territorial waters and the transit lane measuring seven miles wide 1. The agreement followed talks in Tehran between Foreign Minister Abbas Araghchi and Omani counterpart Badr Albusaidi, who also discussed a mine-clearing project in the strait 12. Bloomberg reported the IRGC said the arrangement includes revenue sharing between the two countries 3. Gharibabadi said the strait will not be considered open until the United States meets its commitments under the June memorandum of understanding, including sanctions relief and release of frozen Iranian assets, and separately disputed Trump's claim that all mines had been cleared from the waterway's international waters 1.

Analysis
Iran is very unlikely to declare the strait open to normal international shipping before November, having conditioned reopening on US sanctions relief and asset releases Washington shows no sign of granting. The Iranian-controlled routing and disclosed revenue-sharing arrangement with Oman, details absent from the August 5 agreement, suggest Tehran is consolidating jurisdictional and economic control over the waterway rather than moving toward genuine de-escalation, a reading reinforced by its rejection of Trump's mine-clearance claim. Confidence is moderate, resting on Gharibabadi's on-the-record conditions while the actual US sanctions-relief timeline stays unobservable from open sources; Bloomberg and Al Jazeera provide independent primary reporting corroborated by France 24, yielding broad convergence rather than single-source repetition. Continued closure keeps Gulf war-risk premiums and US Central Command's naval posture elevated, deferring any easing shippers and insurers might otherwise price in.
