The United States and Iran signed a virtual memorandum of understanding on June 15, 2026, to end the war and reopen the Strait of Hormuz [1, 2, 3].

This agreement marks a significant shift in geopolitical tensions by addressing the U.S. blockade of Iranian ports and restoring the flow of oil through one of the world's most critical maritime chokepoints [1, 2].

Under the terms of the memorandum, the two nations will begin a 60-day window for nuclear-non-proliferation negotiations [1]. The deal includes the lifting of U.S. sanctions and the unfreezing of Iranian assets to facilitate a return to diplomatic stability [1, 2]. Additionally, the agreement establishes a reconstruction fund totaling $300 billion [1].

U.S. President Donald Trump (R) and Vice President JD Vance (R) signed the document virtually [1, 2]. Iranian President Masoud Pezeshkian said the electronic agreement was confirmed [1]. The move allows Iran to sell oil freely as the U.S. ends its blockade of the region's ports [1, 3].

The virtual signing ceremony was designed to expedite the cessation of hostilities and create a structured path toward a permanent nuclear deal [1, 2]. The immediate priority remains the reopening of the Strait of Hormuz to ensure global energy security, and stabilize oil markets [1, 3].

Officials said that the 60-day period will serve as a critical testing ground for the viability of the new diplomatic framework [1]. Both nations are expected to monitor compliance with the ceasefire and the lifting of economic restrictions during this timeframe [1, 2].

The agreement establishes a reconstruction fund totaling $300 billion.

The agreement represents a strategic attempt to decouple immediate economic and maritime stability from the long-term complexities of nuclear disarmament. By prioritizing the reopening of the Strait of Hormuz and the release of frozen assets, the U.S. and Iran are creating economic incentives to prevent a return to open conflict while using the 60-day window to determine if a sustainable nuclear framework is possible.
