Iran has suspended its obligations under a memorandum of understanding with the U.S. concerning navigation arrangements and fees in the Strait of Hormuz.
The move threatens to further destabilize one of the world's most critical oil transit chokepoints during an active military conflict. Because the agreement manages navigation rights and fees, its collapse could lead to increased maritime friction and economic volatility in the Gulf region.
Kazem Gharibabadi, Iran's deputy foreign minister, said the country suspended its commitments on July 13 [2]. The decision comes as a war between the U.S. and Iran has been ongoing for five months [1].
Iranian officials have indicated that the resumption of the agreement depends entirely on American action. A spokesperson for the Iranian Foreign Ministry said Monday, July 13, that Tehran will not adhere to the memorandum if Washington does not fulfill its own obligations [3].
This stance was echoed by Iran's chief negotiator. Mohammad Bagher Qalibaf said Wednesday, July 15, that Iran will not commit to the memorandum if the country does not benefit from it [4].
Despite these suspensions, some reports indicate that negotiations continue regarding the potential for Washington to resume work on the navigation arrangements [5]. The tension centers on whether the U.S. will provide the guarantees Iran demands before re-engaging with the agreement.
Control over the Strait of Hormuz remains a primary strategic objective for both nations. The current diplomatic deadlock reflects the broader breakdown in relations as the five-month conflict continues to escalate [1].
“Iran has suspended its obligations under a memorandum of understanding with the U.S.”
The suspension of the memorandum of understanding removes a critical diplomatic guardrail in the Strait of Hormuz. By linking navigation fees and rights to broader political guarantees, Iran is using its geographic leverage over global energy shipping to pressure the U.S. during an active war. The outcome of these negotiations will likely determine whether maritime tensions escalate into a full blockade or a structured ceasefire.
