The United States and Iran signed a digital memorandum of understanding on June 15, 2026 [1], to end their current war [1].

This agreement is critical because it addresses the closure of the Strait of Hormuz, a primary artery for global oil shipments. By extending the cease-fire, the two nations aim to prevent further military escalation in a region that has remained volatile since February [2].

The deal was signed remotely via digital signatures between President Donald Trump and Iran's top negotiator [1]. The primary objectives of the memorandum are to formally end the conflict, extend the existing cease-fire, and reopen the strategically vital Strait of Hormuz [1, 2].

The conflict began in February 2026 following joint U.S. and Israeli strikes on Iranian territory [3]. Since then, the resulting instability has threatened international energy markets and regional security. The new agreement seeks to stabilize these tensions through a structured diplomatic framework [3].

As part of the terms, Iran faces a 60-day deadline to reach a comprehensive nuclear deal [4]. This timeline establishes a narrow window for Tehran to address nuclear proliferation concerns in exchange for the cessation of hostilities, and the restoration of maritime access [4].

President Trump said the U.S. and Tehran have reached a peace deal [1]. The digital nature of the signing reflects the continued diplomatic distance between the two governments, even as they seek to avoid further combat [1, 2].

The agreement represents a pivot from direct military confrontation to a time-bound diplomatic ultimatum. By linking the reopening of the Strait of Hormuz to a 60-day nuclear negotiation window, the U.S. is using maritime economic stability as leverage to secure nuclear concessions from Tehran.
