US and Iran Reach Agreement to End War and Reopen Strait of Hormuz

The United States and Iran have reached a sweeping agreement to end their 15-week war, committing to a permanent ceasefire and the immediate reopening of the Strait of Hormuz. The breakthrough, mediated by Pakistan and Qatar, halts a conflict that began in late February and severely disrupted global energy markets. The cessation of hostilities marks a critical turning point in a war that began with U.S. and Israeli airstrikes—which killed Iranian Supreme Leader Ali Khamenei—and quickly escalated into a regional crisis involving naval blockades, drone swarms, and ballistic missile barrages across the Middle East.[1][2][4]

President Donald Trump announced the agreement while attending the Group of Seven (G7) summit in Evian-les-Bains, France, declaring that the deal is "all signed" and that the vital waterway is already partially open. Under the framework, the U.S. will lift its naval blockade on Iranian ports, while Tehran has agreed to cease military operations on all fronts. The formal signing of the memorandum of understanding is scheduled for Friday in Geneva, Switzerland, where representatives will cement the terms that took weeks of intense back-channel diplomacy in Islamabad and Doha to finalize.[1][2][3][6]

The economic relief was immediate and pronounced across global markets. Global oil prices slid 4 percent to roughly $84 a barrel at the start of trading on Monday, reflecting market optimism that the 20 percent of the world's daily crude supply that transits the Strait of Hormuz will soon flow freely again. The closure of the strait had triggered a severe global energy bottleneck, prompting fears of a prolonged recession and spiking inflation. Stock markets rallied on the news, with investors reacting positively to the prospect of stabilized supply chains and significantly reduced geopolitical risk premiums.[4][5]

Despite the celebratory tone in Evian-les-Bains, significant friction remains over the deal's implementation on the ground. A major sticking point is the status of Lebanon, where Israel has pushed its ground invasion deeper to target Hezbollah militants. Iranian officials insist the ceasefire covers all fronts, including Lebanon, but Israeli Prime Minister Benjamin Netanyahu has not agreed to withdraw forces from the occupied southern territory. Trump expressed frustration with the situation, telling reporters he was "not happy with the way Israel has handled themselves with Lebanon and with Hezbollah," suggesting a growing rift over the war's conclusion.[1][4][6][7]

Another brewing conflict centers on the long-term control and management of the Strait of Hormuz. While U.S. Vice President JD Vance stated the waterway will be open "in a toll-free way for the long term," Iranian state media reported that Tehran only intends to pause "service fees" for 60 days before resuming charges on transiting vessels. European leaders at the G7, fiercely committed to freedom of navigation, have pushed back against any formulation that allows Iran to toll international shipping, viewing it as an unacceptable concession that could set a dangerous precedent for global maritime law.[3][8]

To help secure the strait and enforce the fragile agreement, French President Emmanuel Macron offered to dispatch fighter aircraft for observation flights and deploy France's nuclear-powered aircraft carrier, which is already stationed in the Middle East. The offer reflects a broader G7 effort to stabilize the region, even as several European leaders remain highly critical of Trump's unilateral decision to launch the war in February without consulting NATO allies. The European intervention aims to ensure the waterway remains open without relying solely on American naval power, which has been stretched thin by the recent blockade operations.[3][6]

The ceasefire agreement also paves the way for a critical 60-day window of technical negotiations regarding Iran's nuclear program. The talks will focus heavily on the status of Iran's highly enriched uranium stockpile, which remains a central driver of the broader conflict. Tehran is expected to repeat its pledges not to acquire nuclear weapons and will engage in detailed discussions with U.S. officials. In exchange for verifiable constraints on its nuclear ambitions, Iran is anticipated to receive significant economic incentives, including the release of billions of dollars in frozen assets and targeted sanctions relief.[4][8]

While the truce marks a massive de-escalation, geopolitical analysts warn that the underlying structural tensions mean the region remains highly volatile. Iran emerges from the conflict with a battered economy and degraded military capabilities, but its regime survived the initial decapitation strikes. As diplomats prepare for the Geneva signing, the success of the agreement will depend entirely on whether the U.S. and Iran can navigate the fraught 60-day nuclear negotiation window without triggering another cycle of retaliation, or allowing the ongoing Israeli operations on the Lebanon front to derail the broader peace framework.[4]
