The United States and Iran have reportedly reached a deal for a 60-day cease-fire extension [1] and a memorandum of understanding regarding the Strait of Hormuz.

The agreement is critical because the Strait of Hormuz is a primary artery for global oil shipments. Restoring free navigation would reduce regional tensions and stabilize energy markets that have been volatile due to hostilities.

According to reports dated May 30, 2026 [2], the memorandum includes provisions to lift restrictions on the waterway. Trey Yingst said in a Fox News interview that the memorandum would effectively open the Strait of Hormuz to unrestricted navigation.

However, the deal faces significant hurdles. Middle East Eye reported on May 28, 2026, that Iran has rejected terms proposed by President Trump to lift the Hormuz blockade, calling those terms unacceptable. This contradicts reports that a final agreement on navigation has been secured.

Internal U.S. dynamics also complicate the timeline. An unnamed White House official said via Breitbart that Trump will only make an Iran deal that satisfies his redlines, which include security guarantees for the region. While some reports suggest the deal is imminent, others indicate it still requires the president's final approval.

The proposed 60-day window [1] is intended to end immediate hostilities and allow for further diplomatic negotiations. The strategic waterway, located between Oman and Iran, remains a primary flashpoint for military escalation in the Middle East.

The memorandum would effectively open the Strait of Hormuz to unrestricted navigation.

The discrepancy between U.S. reports and Iranian responses suggests that while a framework for a cease-fire exists, the specific terms of maritime access remain a point of contention. If the 60-day extension is implemented without a resolution on the Strait of Hormuz, the region may see a temporary pause in combat without a long-term solution to the blockade.
