The United States and Iran signed a peace memorandum in Switzerland to halt military fighting and reopen the Strait of Hormuz [1, 2].

The agreement marks a critical attempt to end the U.S.–Iran war and stabilize global energy markets. By lifting naval blockades and resuming diplomacy, the two nations aim to prevent further escalation in a volatile region [1, 3].

The pact, first reported on June 15, 2026 [1], establishes a framework to stop military operations on all fronts. It specifically targets the reopening of the Strait of Hormuz for oil transit, and the removal of the U.S. naval blockade on Iranian ports [1, 3].

President Donald Trump said, "I hope to put war in ‘rearview mirror’" [1].

While the memorandum provides an immediate cessation of hostilities, it does not resolve all regional tensions. The security situation in Lebanon remains unsettled, leaving a significant gap in the broader peace effort [1, 3].

Diplomatic efforts are expected to accelerate immediately following the signing. Iran's foreign minister said, "New talks on nuclear arms and sanctions relief will start on Friday, right after the initial agreement is signed" [1].

Global markets have reacted to the news with a decline in oil prices [3]. Analysts said the deal was expected to pave the way for further talks and stabilize the flow of energy [1].

"I hope to put war in ‘rearview mirror’."

The memorandum serves as a tactical ceasefire rather than a comprehensive peace treaty. By prioritizing the Strait of Hormuz, the U.S. and Iran are addressing the most immediate economic pressure point—global oil supply—while deferring more complex geopolitical disputes, such as the stability of Lebanon and the specifics of nuclear sanctions, to future negotiations.
