US and Iran Edge Toward Strait of Hormuz Deal as Ceasefire Hangs in the Balance

A one-page memorandum of understanding could break the two-month standoff over the world's most critical oil chokepoint — but deep mistrust on both sides leaves the outcome uncertain.

A One-Page Memo That Could Reshape the Middle East

After 68 days of conflict that has disrupted global oil supplies, stranded hundreds of commercial vessels, and tested the limits of a fragile ceasefire, the United States and Iran are quietly negotiating a one-page memorandum of understanding that could end the standoff over the Strait of Hormuz.

The proposed deal, revealed by officials familiar with the negotiations, would see Iran ease its grip on the strategic waterway while the U.S. gradually lifts its naval blockade of Iranian ports over a 30-day period. Within that window, both sides would work toward a broader nuclear agreement.

President Donald Trump, speaking from the Oval Office on May 6, expressed confidence that a deal was within reach. “They want to make a deal badly,” he said. “Iran cannot have a nuclear weapon, and they won’t. And they’ve agreed to that, among other things.” When pressed on whether there was a deadline, Trump was characteristically vague: “Never a deadline. It’ll happen.”

How We Got Here

The conflict began on February 28, 2026, when Trump announced “major combat operations” against Iran, launching massive joint U.S.-Israeli strikes targeting military, government, and infrastructure sites across the country. What followed was weeks of intense fighting that drew in regional actors and sent shockwaves through global energy markets.

A ceasefire was declared in early April, but Iran moved quickly to tighten its hold on the Strait of Hormuz — the narrow waterway through which roughly one-fifth of the world’s oil supply transits daily. Iran’s Revolutionary Guards attacked commercial vessels, laid mines, and told non-aligned ships they could only pass by paying a toll. Hundreds of ships from 87 countries remain stranded, carrying weeks’ worth of oil, gas, fertilizer, and other goods.

Then came “Project Freedom.” On May 4, Trump announced a U.S. military-led effort to escort ships through the strait, involving guided-missile destroyers, over 100 aircraft, and 15,000 service members. The results were immediate and violent. Iran fired missiles and drones at ships under U.S. protection. The U.S. Navy sank six Iranian boats. The UAE came under attack for the first time since the ceasefire, with two cargo vessels reported ablaze off its coast.

Within 24 hours, Trump abruptly paused the operation, citing progress in talks — a whiplash that underscored how volatile the situation remains.

The Sticking Points

Despite the diplomatic momentum, significant hurdles remain.

The toll issue. Iran has insisted on charging commercial vessels for safe transit through the strait. The U.S. views any such arrangement as unacceptable extortion. This remains an unresolved point in the MoU negotiations.

Iranian hardliners. Not everyone in Tehran is on board. Ebrahim Rezaei, a senior member of Iran’s parliament, posted on X that reports of a near-deal were merely “Americans’ wish list” and warned that “Iran has its finger on the trigger.” He threatened a “harsh and regret-inducing response” if the U.S. does not offer sufficient concessions.

The nuclear question. While the current MoU reportedly contains terms related to Iran’s nuclear program, most specifics would be negotiated during the 30-day window — a period that could easily collapse if trust erodes.

Israel’s parallel war. Adding to the complexity, Israel continues to strike targets in Lebanon. On May 6, Israeli forces bombed Beirut targeting a Hezbollah commander, a move that could inflame regional tensions and complicate U.S.-Iran negotiations.

Global Stakes

The standoff at Hormuz has already pinched economies worldwide. Oil prices have risen sharply. The shipping industry remains deeply skeptical — BIMCO, a leading maritime trade group, says it has received no formal guidance from the U.S. about security guarantees. Jakob Larsen, BIMCO’s chief safety officer, warned that without Iran’s consent for safe transit, “it is currently not clear whether the Iranian threat to ships can be degraded or suppressed.”

The U.S.-led Joint Maritime Information Center has advised ships to use Oman’s waters and avoid usual routes, which “should be considered extremely hazardous due to the presence of mines that have not been fully surveyed and mitigated.”

What’s Next

The ball is now in Iran’s court. Multiple drafts of the MoU have been exchanged, and the Trump administration is waiting for Tehran’s response on several outstanding issues. Pentagon chief Pete Hegseth has described the Hormuz operation as “separate and distinct” from the broader Iran war — a semantic distinction that may matter more in Washington than on the water.

If the MoU holds and both sides honor the 30-day de-escalation window, it could mark the beginning of the end of a conflict that has roiled the Middle East and rattled global markets. If it fails, the Strait of Hormuz could become the flashpoint for an even deadlier chapter.

For now, hundreds of ships and tens of thousands of sailors wait — caught between diplomacy and disaster.
