The first major diplomatic test of the US-Iran memorandum of understanding arrives with the abrupt postponement of technical talks in Switzerland.

The US and Iran postponed technical talks scheduled for Friday in Switzerland, injecting uncertainty into the 60-day framework signed just two days earlier to end hostilities and restore Strait of Hormuz traffic.
"The planned talks between the US, Iran, Qatar and Pakistan have been postponed. Switzerland remains ready to facilitate these talks," the Swiss Foreign Ministry said in a statement, adding that preparatory work at the Bürgenstock resort was continuing.
Vice President JD Vance scrapped his planned trip to Switzerland for the signing ceremony and follow-up negotiations, the White House confirmed Thursday night. The delay comes despite early progress: Vance said the US naval blockade had been lifted and Iran had refrained from firing on ships for two consecutive days, with nearly 13 million barrels of oil passing through the Strait of Hormuz on Wednesday night alone. Gas prices have since fallen below $4 a gallon, according to AAA.
The postponement tests whether the 14-point memorandum — which includes a $300 billion reconstruction fund for Iran, oil export waivers, and a nuclear negotiation timeline — can survive its first logistical hurdle. If talks slip beyond the 60-day window, Trump has said Iran gets "no money, not ten cents," while military options remain on the table.
Israel-Hezbollah Clashes Complicate the Diplomatic Window
The diplomatic setback unfolded alongside renewed violence in Lebanon. Israel struck more than 80 Hezbollah targets and killed dozens of militants after four Israeli soldiers died in southern Lebanon on Friday, including a battalion commander. Prime Minister Benjamin Netanyahu vowed Hezbollah would pay a "very heavy price," highlighting the fragility of a separate ceasefire that went into effect Friday afternoon.
The cross-border escalation threatens to pull Washington and Tehran back toward confrontation even as both sides test the MOU's terms. Iran backs Hezbollah, and any major escalation risks collapsing the diplomatic track before technical talks resume.
The $300 Billion Question
One of the most contentious elements of the framework — a proposed $300 billion private investment fund for Iran's reconstruction — faces legal obstacles that could complicate any final deal. The State Department formally determined in 2020, and again in May 2025, that Iran's construction sector is controlled by the Islamic Revolutionary Guard Corps, triggering sanctions risks under the Iran Freedom and Counter-Proliferation Act.
"The simple fact is that the only way the Iranians get any of those resources, not a single penny, by the way, from the United States of America under any circumstances," Vance told reporters, seeking to reassure critics. But Miad Maleki, a senior fellow at the Foundation for Defense of Democracies and a former Treasury OFAC executive, said congressional approval would be "unavoidable for a durable version of that investment."
Market Signals Point to Cautious Optimism
Early data suggests the MOU is already shifting behavior in the Strait of Hormuz, through which about 21 percent of global oil trade passes. Kpler, a data and intelligence company, recorded 25 verified Strait of Hormuz crossings on Thursday, a "notable increase in daily maritime activity." Five sanctioned vessels were among the crossings, and no additional physical attacks have been confirmed since May 10.
US Central Command said its forces "remain present and vigilant" in the region, releasing video of F-16 fighter jets conducting patrols. The last time a similar diplomatic framework was attempted with Iran, in 2015, oil prices fell roughly 30 percent over six months as sanctions relief brought Iranian barrels back to market. A repeat scenario would depend on whether the current talks produce a final deal within the 60-day window.
China welcomed the framework as a "dawn of peace," with Foreign Minister Wang Yi telling his Iranian counterpart that "force and power cannot solve problems." On Capitol Hill, Republican reactions were split: Senator Ted Cruz called the $300 billion fund "an exceptionally bad idea," while Senator Lindsey Graham argued the MOU provides "a pathway to diplomacy" that leaves only war as the alternative.
