US and Iran Reach Tentative 60-Day Ceasefire Extension Amid Gulf Tensions

After three months of conflict that has rattled global energy markets and redrawn alliances across the Middle East, the United States and Iran have reached a preliminary memorandum of understanding (MOU) to extend their ceasefire by 60 days and launch a new round of negotiations aimed at permanently ending the war.

What We Know So Far

The tentative deal, first reported by Axios on May 28 and later confirmed by the White House to Al Jazeera, represents the most significant diplomatic breakthrough since the conflict began. Under the framework:

• The ceasefire would be extended by 60 days, providing a window for substantive negotiations toward a permanent end to hostilities.
• Vessel traffic through the Strait of Hormuz would become “unrestricted,” easing the chokehold that has disrupted global oil shipments for weeks.
• The US would lift its naval blockade on Iranian ports, a major concession that has been a key Iranian demand throughout the talks.

However, the agreement still requires President Donald Trump’s final approval — a step that is far from guaranteed given the political pressures surrounding the deal.

The Strait of Hormuz Dispute

At the heart of the negotiations lies the Strait of Hormuz, one of the world’s most critical energy chokepoints. Iran has claimed sovereignty over the strategic waterway, insisting it must be jointly managed by Iran and Oman since it passes through both countries’ territorial waters. Tehran has even proposed a tolling system for commercial vessels.

The US has firmly rejected any form of Iranian control over the strait. In a sharp escalation of pressure, Treasury Secretary Scott Bessent threatened close US ally Oman with sanctions if it facilitates the imposition of fees on ships transiting the waterway.

Trump’s Three Red Lines

Bessent outlined Trump’s conditions for any agreement with Iran:

1. Reopening Hormuz to unrestricted maritime traffic
2. Relinquishing stockpiles of highly enriched uranium
3. Ending Iran’s nuclear program entirely

“It’s always a mistake to get out ahead of the president, so it is all going to be the president’s decision,” Bessent told reporters, underscoring the uncertainty that still hangs over the deal.

Iran’s Response

Not everyone is on board. Iran’s semi-official Tasnim news agency cited a source close to the negotiations who denied claims of an imminent agreement, suggesting that internal Iranian politics could still complicate the process. The gap between US officials’ optimism and Tehran’s cautious signaling indicates that significant hurdles remain.

Adding to the volatility, the two sides traded limited military attacks earlier on Thursday — a stark reminder that the current truce remains fragile and that sporadic skirmishes continue to threaten the diplomatic process.

What’s at Stake

The economic fallout from the conflict has been severe. US inflation surged to a three-year high in data released May 28, driven in large part by energy price spikes linked to the Hormuz disruption. Global oil markets have been on edge, and a credible path to de-escalation would provide significant relief.

For the broader Middle East, the deal could also reshape the regional calculus. Israel’s ongoing military operations in Lebanon, the UN’s recent decision to add Israel to a blacklist for conflict-related sexual violence, and shifting Gulf alliances all form the backdrop against which this ceasefire extension must be understood.

What Comes Next

All eyes are now on the White House. If Trump approves the MOU, the 60-day window would become a high-stakes diplomatic sprint to resolve the fundamental disagreements — Iran’s nuclear ambitions, the status of the Strait of Hormuz, and the broader security architecture of the Persian Gulf.

If he doesn’t, the region risks sliding back into open conflict, with consequences that would reverberate far beyond the Middle East.

The world watches and waits.
