The United States and Iran are preparing to formally sign an interim peace deal that has left both sides claiming victory, with details of the accord still emerging and energy insiders skeptical of how fast it can reopen the Strait of Hormuz.

The text of the so-called memorandum of understanding — which opens the way to two months of negotiations on Iran’s nuclear program and other issues — has yet to be published. A near-final draft seen by Bloomberg News shows Iran set to receive sanctions waivers that allow it to sell oil immediately, with other financial incentives deferred.

A U.S. official said the full accord may be published in the next two days ahead of a signing ceremony. That event is scheduled to take place in the Bürgenstock, a mountain resort overlooking Lake Lucerne, the Swiss foreign ministry said Tuesday. Vice President JD Vance is expected to head the American delegation, while Iran will likely be represented by Parliament Speaker Mohammad Bagher Ghalibaf.

U.S. President Donald Trump is in France for a Group of Seven summit, where the Iran war — which has caused energy prices to soar — is featuring prominently. European nations like France, the UK and Italy are ready to help clear the strait of mines if needed, though they’re wary of potential risks to their ships and skeptical that Hormuz can fully re-open by Friday as Trump has promised.

Speaking at the summit on Tuesday, Trump said the agreement is a “done deal” that will prevent Iran from developing nuclear weapons, adding that the U.S. would not pay war reparations or invest money in Iran. “They’re going have to prove themselves, I think, before any of us go in there,” he said.

Trump also held talks Tuesday with United Arab Emirates President Sheikh Mohamed bin Zayed and Qatar’s Emir Sheikh Tamim bin Hamad. Those countries may play a part in helping create, along with the U.S., a $300 billion development fund for Iran in the aftermath of the conflict.

The draft seen by Bloomberg says the U.S. and its regional partners would create a plan to provide that amount in financing for Iran’s rehabilitation and economic development.

The U.S. will look to other countries and the private sector to pledge investments, the American official said. Iran says the war, which began on Feb. 28 with a U.S.-Israeli bombardment, cost it more than $250 billion in economic damage.

Iranian officials have said the MOU will lead to them getting access to tens of billions of dollars of frozen funds held in places such as Qatar. The draft seen by Bloomberg says the U.S. undertakes that those funds “will be released and made fully available” without setting a timeline.

Oil prices have fallen sharply since Trump said late last week an agreement was imminent. Brent crude dropped below $80 on Tuesday, falling for a fourth straight day and down from a high of $125 in late April.

Lower demand in China, as well as the U.S. and other nations running down their emergency petroleum stockpiles, have also helped lower prices. Those reserves will likely need to be rebuilt once the Hormuz strait is open again.

Many European governments, energy investors and shipping companies have reservations about how fast the strait — through which a significant portion of the world’s supplies of oil, liquefied natural gas and aluminum normally flow — can be returned to pre-war conditions.

Beyond the potential need to clear the waterway, there’s a longer-run question of whether Iran will allow free passage.

Tehran has signaled it will charge vessels navigation fees after the 60-day period of the fresh U.S.-Iran negotiations. Trump said Tuesday at his meeting with the UAE leader that the strait would be “permanently” open-toll free. A day earlier, a senior U.S. official told reporters that the strait’s status beyond the 60-day negotiating period would be up for discussion.

Vance defended the deal on Monday, claiming the pact will build around a verification system to ensure Iran follows through on its pledges. Senate Republicans said they’re pressing the Trump administration for details and signaled Congress will ultimately vote on the final agreement.

Neither the U.S. nor Iran is hiding its distrust of the other. The White House says Trump won’t hesitate to return to strikes if he thinks Tehran’s leaders aren’t abiding by the deal’s terms. Iranian officials have warned that the U.S. twice launched attacks on the country during the past year while negotiations were underway.

Trump’s frustration with the war he launched nearly four months ago has been increasingly visible and his focus has often drifted elsewhere, including to his renovation projects in Washington and festivities surrounding the 250th anniversary of U.S. independence. The president, who turned 80 on Sunday, looked tired when he arrived at the G7 on Monday. He traveled only after attending a mixed martial arts fight at the White House that ended well after midnight in the U.S.

Israel’s war against Iran-backed Hezbollah militants in Lebanon is another potential spoiler to a successful deal. The MOU is likely to state there must be a ceasefire on “all fronts,” including Lebanon.

Ghalibaf said in a call with Lebanese officials that Israel “must withdraw from occupied territories,” Iran’s Mehr news agency reported Tuesday.

Israeli politicians have called for continuing the fight against Hezbollah, which has fired missiles and drones on their territory in support of Iran.
