The United States and Iran reached an initial agreement on June 15, 2026, to end a conflict that began on February 28, 2026, and disrupted global energy markets for more than three months. The deal includes plans to reopen the Strait of Hormuz and extends the ceasefire between the two sides by 60 days, according to statements from President Donald Trump and Iranian officials confirmed by multiple news outlets.
The memorandum of understanding, announced after months of failed negotiations and military escalation, marks a significant shift from the armed conflict that has dominated the region since late February. Trump confirmed on June 15 that the deal was “all signed,” while Iran’s state media and international news agencies including Reuters, NPR, and Al Jazeera reported the framework agreement had been finalized.
Under the initial agreement, Iran will agree not to produce or acquire nuclear weapons, according to reporting from Reuters and other sources. The two sides have set a 60-day window to negotiate the final settlement on Iran’s nuclear program and other broader issues including sanctions relief and reconstruction, according to Democracy Now and Al Jazeera. Iran’s Foreign Ministry stated that the terms dealing with its nuclear program would be finalized within that 60-day period, as reported by CGTN.
The war that preceded this deal began when the United States and Israel launched coordinated strikes on Iran on February 28, 2026, according to Britannica and multiple news timelines. The conflict lasted more than 100 days before the initial ceasefire was announced on April 8, 2026, following 40 days of active fighting, according to Al Jazeera. That ceasefire was repeatedly tested and violated before the latest agreement emerged.
The reopening of the Strait of Hormuz—one of the world’s most critical shipping chokepoints—addresses one of the war’s most disruptive consequences. When Iran closed the strait in early March 2026, it created what Congress.gov described as the largest disruption to world energy supply since the 1970s energy crisis. The closure sent oil prices soaring and threatened global shipping and commerce.
Markets reacted positively to the deal announcement. Oil prices fell over 4 percent following the agreement, according to reporting from Geo News and multiple financial outlets. CNBC reported that Asian stocks rallied on Monday while oil prices tumbled after the U.S. and Iran agreed to the peace deal aimed at ending nearly four months of conflict. Investopedia noted that stock futures climbed and oil prices slid after the announcement, reflecting investor optimism about the end of the disruption.
The official signing of the memorandum of understanding is scheduled for June 19, 2026, in Switzerland, according to Reuters and Le Monde. However, challenges remain. The New York Times noted that despite the agreement, “challenges loom,” and Al Jazeera reported that Israel has not confirmed its support for the deal, with Israeli leaders expressing concern that the agreement does not sufficiently address Iran’s nuclear program.
