Iranian Foreign Minister Abbas Araghchi said Iran alone has authority to manage traffic through the Strait of Hormuz during a visit to Baghdad [1, 2].

The announcement signals a sharp escalation in maritime tensions, as the strait serves as a critical global chokepoint for oil and commercial shipping. By asserting total control, Tehran is leveraging its geographic position to pressure the United States and demand an end to Israeli military operations in Lebanon [1, 2].

Speaking Saturday, June 28, 2024, Araghchi said that any external involvement in the waterway would breach the U.S.–Iran memorandum of understanding (MoU) [1, 3, 4]. He said that Iran holds sole responsibility for managing the strait and that this control would last for the next 30 days [2].

Reports regarding the current status of the waterway vary. Some sources indicate a complete closure to all commercial ships and oil tankers [5], while others suggest the strait was already effectively closed and the announcement served as a reiteration of that status [2].

"Iran alone holds responsibility for managing the Strait of Hormuz, and any external interference would violate the U.S.–Iran MoU," Araghchi said [1].

The move follows accusations from Tehran that the U.S. violated a deal to reopen the waterway. An AP correspondent reported that Iran reversed its previous reopening of the waterway and fired on ships attempting to pass [4].

Araghchi's remarks in Baghdad emphasize Iran's intent to use the maritime corridor as a strategic tool. The foreign minister linked the management of the strait to the cease-fire components of the MoU, and the broader regional conflict involving Lebanon [1, 2].

"Iran alone holds responsibility for managing the Strait of Hormuz, and any external interference would violate the U.S.–Iran MoU."

This assertion of sole authority over the Strait of Hormuz transforms a critical transit point into a direct bargaining chip in regional diplomacy. By linking maritime access to the U.S.–Iran MoU and Israeli actions in Lebanon, Tehran is attempting to force a diplomatic concession through the threat of global energy disruption. The 30-day window suggests a tactical deadline intended to accelerate negotiations or provoke a specific response from Washington.
