US and Iran Reach Tentative Peace Deal to End War and Reopen Strait of Hormuz

The United States and Iran have reached a preliminary memorandum of understanding to end a devastating 100-day war that has reshaped the Middle East and fractured the global energy market. The agreement, announced early Monday after intense mediation by Pakistan and Qatar, establishes an immediate ceasefire, lifts the U.S. naval blockade on Iranian ports, and initiates the reopening of the Strait of Hormuz.[1][4]

U.S. President Donald Trump confirmed the breakthrough on social media late Sunday, declaring the deal complete. "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," Trump wrote, adding, "Ships of the World, start your engines. Let the oil flow!" The formal signing ceremony is scheduled for Friday, June 19, in Geneva, Switzerland.[2][5]

Iranian officials corroborated the core aspects of the framework, though their language was notably more cautious. Deputy Foreign Minister Kazem Gharibabadi stated that the agreement puts an "immediate and permanent end" to military operations on all fronts. However, Iranian state media emphasized that Tehran's full compliance would not begin until the ink is dry on Friday, framing the deal as a victory that forced Washington to abandon its blockade.[3][4][6]

The economic relief was instantaneous. Global markets, which had been suffocated by the effective closure of the Strait of Hormuz since late February, rallied aggressively. Brent crude futures plunged more than 4% to roughly $83.60 a barrel, while U.S. West Texas Intermediate slid 4.6%. Asian equities surged, with indices in Tokyo and Seoul climbing more than 5% as the threat of a prolonged energy shortage evaporated.[5][8]

The Strait of Hormuz is a vital maritime chokepoint through which roughly 20% of the world's crude oil and significant volumes of natural gas and fertilizer transit. Its closure by Tehran—in retaliation for initial U.S. and Israeli strikes—triggered a historic energy shock. While Trump demanded a "toll-free" reopening, Iranian semi-official media reported that the waterway's management would resume over a 30-day period under "Iranian arrangements," hinting at lingering friction over maritime sovereignty.[5][8]

Beyond the immediate resumption of shipping, the memorandum outlines a highly precarious 60-day negotiation window to address Iran's nuclear ambitions. The war began in part to neutralize Tehran's atomic infrastructure, which had enriched uranium to 60% purity—a short technical step from weapons-grade material. The U.S. is demanding the destruction or removal of this stockpile, while Iranian officials have proposed diluting the uranium domestically.[1][3][7]

If the two sides fail to reach a comprehensive nuclear accord within those 60 days, the ceasefire could collapse. Trump has reportedly threatened to resume military strikes if a final nuclear resolution is not achieved, while the draft agreement also stipulates the phased release of up to $24 billion in frozen Iranian assets, contingent on Tehran's compliance.[3][6][7]

A major complication remains the ongoing conflict in Lebanon. The draft agreement explicitly calls for a cessation of hostilities on all fronts, which Iran interprets as including the fighting between Israel and the Iranian-backed militia Hezbollah. However, Israeli Prime Minister Benjamin Netanyahu reportedly informed the U.S. administration that Israel does not consider itself bound by the Lebanon-related provisions of the U.S.-Iran memorandum.[2][3]

Israel's continued military operations, including a recent airstrike on Beirut's southern suburbs just hours before the deal was finalized, nearly derailed the talks. Iranian Parliament Speaker Mohammad Bagher Ghalibaf cited the strike as evidence that Washington lacks the ability to control its allies, though Tehran ultimately chose not to retaliate and proceeded with the ceasefire framework.[1][6]

Domestically, the agreement faces intense scrutiny in both nations. In Tehran, hardline factions have staged protests, accusing the negotiating team of treason for making concessions to Washington. Iranian President Masoud Pezeshkian has been forced to publicly defend the diplomats, arguing that ending the war and lifting sanctions is essential for the nation's survival.[6]

In the United States, the deal has drawn sharp criticism from foreign policy hawks within the Republican Party. Critics argue that the framework fails to achieve the war's original objectives—namely, the complete elimination of Iran's nuclear program and the dismantling of its proxy networks—and instead rewards Tehran with billions in unfrozen assets and renewed leverage over global shipping.[1][3]

Despite the skepticism, European leaders breathed a collective sigh of relief. U.K. Prime Minister Keir Starmer called the breakthrough a "hugely important step forward," while French President Emmanuel Macron and EU Commission President Ursula von der Leyen emphasized that restoring toll-free freedom of navigation is an indispensable condition for the global economy. As diplomats converge on Geneva for Friday's signing, the world watches to see if this fragile truce can evolve into lasting stability.[5][6]
