US, Iran Set New Nuclear and Sanctions Talks After Switzerland MoU Signing

The MoU signing is set for Friday, June 19, at the Burgenstock resort overlooking Lake Lucerne, and Switzerland said the venue—“perched high above Lake Lucerne” and difficult to access because water surrounds it on three sides—was proposed by “the Pakistani and Qatari mediators, as well as by the US and Iran.”
Iran’s top negotiator Mohammad Bagher Ghalibaf will attend the signing, and the U.S. delegation will be led by Vice President JD Vance, with reporting that “Trump might also attend.” Iranian Foreign Minister Abbas Araghchi said negotiations would begin “likely on Friday” once the MoU is signed.
Trump linked the deal momentum to immediate shipping movement in the Strait of Hormuz, saying: “Ships are starting to move, many loaded up with Oil, out of the Strait of Hormuz,” and he added he did not “think we will need much help” keeping the waterway open—while France 24 reported the U.S. “imposed its own blockade on Iranian ports” in retaliation.
Crypto reporting provided specific U.S. enforcement actions around Iranian-linked exchanges: the U.S. Treasury sanctioned “Nobitex and three other Iranian exchanges,” and CryptoBriefing reported that by late May the U.S. had seized “approximately $1 billion in Iranian digital assets.”
Iran and the United States will hold a formal signing ceremony on Friday, June 19, at Switzerland's Bürgenstock Resort above Lake Lucerne, setting off a 60-day window of nuclear and sanctions talks. Xinhua reported that Iranian Foreign Minister Abbas Araghchi said negotiations would begin "likely on Friday" the moment the memorandum of understanding is signed.
The deal caps a rapid sequence: war began February 28, a naval blockade followed in April, and Pakistani and Qatari mediators brokered a ceasefire text in Islamabad on June 12. By June 17, the first Iranian tankers — carrying 3.8 million barrels of crude — had already left the blockade zone.
Vice President JD Vance will lead the U.S. delegation at the signing. Iran's lead negotiator, Majlis Speaker Mohammad Bagher Ghalibaf, will represent Tehran. The Australian reported that Trump might also attend the ceremony at the resort, which sits high above Lake Lucerne and is reachable only by funicular or boat — making it easy to secure.
Switzerland said the venue was proposed by "the Pakistani and Qatari mediators, as well as by the US and Iran." Pakistan is the official depositary of the agreement. Qatar handled sensitive back-channel communications. Vance described the MoU itself as a "very general document" of roughly 1.5 pages, with technical nuclear details left for the 60-day talks ahead.
Trump announced the deal's progress with a blunt message: "Ships of the World, start your engines. Let the oil flow!" He said ships were already moving out of the Strait of Hormuz "loaded up with Oil." The Strait carries 25% of the world's seaborne oil. Its closure cost Iran roughly $500 million per day at its peak.
Markets responded fast. Brent crude dropped about 10% this week, falling to around $78.74 per barrel. Voice of Emirates noted that the MoU framework is designed to lock in shipping-security steps. The MoU also requires Iran to remove sea mines and return merchant shipping to pre-war levels within 30 days.
Morning Chronicle reported that U.S. analysts and Senate critics have called the document "dangerously vague." The Washington Post editorial board flagged the withholding of the full text as a "red flag," suggesting the administration is hiding a lack of real nuclear concessions. Key omissions include plutonium and Iran's proxy relationships, such as its support for Hezbollah.
Iran linked the deal to Lebanon directly. If Israel continues strikes there, Tehran warned the MoU would be considered void. Israel has signaled defiance, viewing the Lebanon ceasefire clause as a protection for Hezbollah. Trump has threatened that attacks on Iran "could resume" if no final nuclear accord is reached within the 60-day window.
On June 2, the U.S. Treasury launched "Operation Economic Fury," sanctioning four Iranian crypto exchanges — Nobitex, Wallex, Bitpin, and Ramzinex. By late May, the U.S. had already seized approximately $1 billion in Iranian digital assets. Fox 26 reported that crypto markets improved on MoU expectations, but analysts warned a "digital blockade" would remain even as physical ports reopened.
Iran expects $24 billion to $25 billion in frozen funds to be released during the 60-day window, according to CBS News and Xinhua. Unconfirmed reports point to a possible $300 billion reconstruction fund for Iran, financed through private corporations rather than direct U.S. aid. IAEA inspectors are expected back in Iran to oversee destruction of highly enriched uranium stockpiles under the framework.
