President Donald Trump announced on June 15, 2026 that the United States and Iran have reached an agreement to end their war, ordering the immediate lifting of the U.S. naval blockade of Iranian ports and the reopening of the Strait of Hormuz. The announcement, made on Trump's 80th birthday, follows months of negotiations mediated in part by Pakistan that resulted in a finalized memorandum of understanding. The agreement ends a conflict that began on Feb. 28 with U.S. and Israeli strikes on Iran, including an operation that killed Supreme Leader Ayatollah Ali Khamenei, and escalated into a broader confrontation involving Iranian proxies, Israeli operations in Lebanon, and Iranian attempts to disrupt shipping through the Strait of Hormuz.
In a post on Truth Social on Sunday, June 15, 2026, Trump wrote: "The Deal with the Islamic Republic of Iran is now complete. Congratulations to all! I hereby fully authorize the toll-free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade. Ships of the World, start your engines. Let the oil flow!"
Agreement Terms and Switzerland Signing Ceremony
Pakistani Prime Minister Shehbaz Sharif confirmed that a memorandum of understanding had been finalized, with a formal signing ceremony scheduled for Friday, June 19, 2026, in Switzerland. The agreement calls for the immediate and permanent termination of military operations on all fronts, including in Lebanon.
A statement from the Secretariat of the Supreme National Security Council of Iran said the text of the Memorandum of Understanding on the End of War Negotiations (Islamabad Negotiations) between Iran and the United States was finalized on the evening of June 14. The statement said: "Based on the agreements reached, the war and military operations on all fronts, including Lebanon, will end immediately and permanently as of tonight, and in addition, the naval blockade against Iran will end immediately and completely."
Details of the full agreement remain limited, but officials indicated it includes a ceasefire, reopening of the strait to international shipping, and initial steps toward sanctions relief for Iran.
War Origins and Escalation Timeline
The war began on Feb. 28 with U.S. and Israeli strikes on Iran, including an operation that killed Supreme Leader Ayatollah Ali Khamenei. The conflict escalated into a broader confrontation involving Iranian proxies, Israeli operations in Lebanon, and Iranian attempts to disrupt shipping through the Strait of Hormuz, one of the world's most critical oil chokepoints. The U.S. imposed a naval blockade in response, contributing to global energy market disruptions and fuel shortages.
Nuclear Program Negotiations and 60-Day Timeline
Core issues such as Iran's nuclear program are expected to be addressed in follow-on negotiations over the next 60 days. Trump has repeatedly stressed that any deal must prevent Iran from acquiring a nuclear weapon. The Iranian statement said: "Negotiations for a final agreement will be postponed until after the other party has fulfilled its obligations in accordance with the Memorandum of Understanding."
Israeli Caution, Iranian Confirmation, and Market Response
White House officials described the pact as a significant diplomatic achievement that ends active hostilities while protecting U.S. interests and those of its ally Israel. Israeli officials have expressed caution, with some reports indicating ongoing concerns about Iran's missile capabilities and regional influence.
Iranian state-affiliated media confirmed the agreement's text had been finalized and that Tehran views it as ending the conflict. The Islamic Republic of Iran statement said it "appreciates the efforts of the Islamic Republic of Pakistan and the Government of Qatar."
Markets reacted positively in after-hours trading on Sunday, June 15, 2026, with oil prices dropping sharply on expectations of restored flows through the Strait of Hormuz. The development marks a sudden de-escalation after weeks of brinkmanship, including recent U.S. strikes and threats of further escalation. Trump had earlier canceled planned additional bombings, citing progress in talks.
