The first round of the US-Iran peace talks in Switzerland has concluded with a flurry of bold pronouncements and a 60-day roadmap towards a final deal.
But beneath the surface of this diplomatic breakthrough lies a fragile and deeply contested framework. The high-stakes negotiations, held at the Bürgenstock resort, have produced tangible, if temporary, shifts: the US Treasury has issued a 60-day waiver on Iranian oil sanctions allowing Tehran to sell crude in US dollars for the first time in decades, and a tentative agreement has been reached to reopen the Strait of Hormuz to commercial traffic.
Maritime tracking platform Kpler reported that 36 vessels transited the strait on Monday, the highest daily volume recorded since 1 March.
Iranian officials have stated that the operational architecture for the 60-day negotiation period will be structured around four principal committees: nuclear affairs, sanctions, compliance monitoring, and reconstruction.
Technical deliberations will be overseen by Iran’s lead negotiator, Mohammad Bagher Ghalibaf, and US Vice President J D Vance, who led the American delegation. Meanwhile, Pakistani Prime Minister Muhammad Shehbaz Sharif expressed his confidence that the memorandum of understanding (MoU) signed between Tehran and Washington would evolve into a long-term agreement after the initial 60-day window.
This rapid progression is a remarkable development, revealing how quickly strategic calculations can shift once war exposes the prohibitive costs of continued confrontation.
The US suspension of sanctions on Iranian oil, in particular, is a significant geopolitical signal, and the financial markets immediately grasped its importance. Brent crude retreated as traders priced in the prospect of additional Iranian oil returning to global markets, while fears surrounding the Strait of Hormuz began to recede.
But the decline in oil prices reflected something more profound than expectations of increased supply: the markets were effectively assigning a higher probability to political stability in one of the world’s most strategically vital waterways.
Regional diplomatic efforts have also continued apace. On Tuesday, Sultan Haitham bin Tariq Al Said of Oman received an Iranian delegation including Ghalibaf and Foreign Minister Abbas Araghchi to discuss the latest developments in the US-Iran negotiations.
The Sultanate has emerged as a pivotal intermediary, particularly on matters related to maritime traffic through the Strait of Hormuz. Concurrently, Iranian President Masoud Pezeshkian arrived in the Pakistani capital Islamabad on Tuesday to hold talks with Pakistani officials regarding the negotiations with Washington.
Pezeshkian had previously emphasised that regional problems would subside if all the terms of the agreement were implemented.
An Iranian diplomat with close knowledge of the talks told Al-Ahram Weekly that the inaugural round had proceeded favourably, reinforcing the impression that Washington is genuinely intent on charting a new course with Tehran.
“The talks between Tehran and Washington represent diplomacy at its most exacting,” he observed. “The fact that the initial signals are encouraging is, in itself, telling.”
Yet he cautioned against premature optimism. “The path ahead is long and fragile and is capable of unravelling at any juncture. Still, the recent gestures on both sides, in Tehran as much as in Washington, suggest that the tide is turning towards those who want a deal, not those who want to bury it.”
Before departing from Switzerland, Ghalibaf declared that Iran had succeeded in ending the war and lifting the blockade through a combination of dialogue and ground-level strength.
“Hopefully, we can activate the strait again in terms of passage and bring prosperity back to the regional and global economy,” he said, while stressing that the Strait of Hormuz would be managed by Iran “and follow international laws”.
He also reaffirmed Iran’s commitment to securing Lebanon’s territorial integrity, insisting that without diplomacy, “many lives in Lebanon would have been lost.” In response to criticism from hardliners at home, he characterised the negotiations as a “form of struggle” and asserted that “however successful military action may be, its gains cannot be consolidated without diplomacy.”
The most immediate point of contention between Washington and Tehran crystallised around Iran’s nuclear programme.
Vance hailed a significant victory, declaring that Iran had agreed to invite International Atomic Energy Agency (IAEA) inspectors back into the country. “That is a major milestone for the American people, and the first step in permanently denuclearising or permanently ending a nuclear weapons programme in Iran,” he stated.
This claim was swiftly refuted by Tehran. Iran’s Foreign Ministry told state media that it had made “no new commitments” on nuclear inspections and emphasised that any future arrangements remain subject to approval by the Supreme National Security Council.
This disagreement underscores the fact that while the US views the return of the inspectors as a foundational pillar of the deal, Iran is treating it as a highly negotiable, and currently unresolved, element of the second-phase talks.
This should not, however, be interpreted as evidence that the negotiations are failing. US and Iranian negotiators frequently present the same discussions differently to satisfy domestic political audiences while preserving enough ambiguity to keep the talks alive.
Vance himself acknowledged the complexity of the process. “We made great progress,” he said after nearly 18 hours of negotiations, adding that technical teams would remain in Switzerland because “they’re going to be working with proper oversight to make sure that we are accomplishing the objectives that matter for everybody.”
The economic dimension of the agreement is equally complex and serves as a barometer of the war’s punishing toll on both sides. The US Treasury’s issuance of a general licence authorising the production, sale, and transport of Iranian crude and petrochemicals until 21 August represents a dramatic dismantling of central pillars of the long-running embargo.
It allows for payments in US dollars and even permits the import of Iranian oil into the US, a move that would have been unthinkable just months ago.
Vance framed this economic relief as a conditional lever, stating that “our plan under this deal is, again, the Iranians are getting a lot of benefits so long as they dismantle that nuclear weapons programme.”
He further suggested that some of Iran’s frozen assets could be channelled to buy American agricultural goods like soy, corn, and wheat in a proposal that aims to turn economic relief into a direct benefit for US farmers while maintaining a degree of control over Tehran’s spending.
Ghalibaf confirmed that arrangements had been made for the release of $12 billion of Iran’s frozen assets in Switzerland.
However, the Central Bank of Iran responded by stressing that Tehran was under no legal obligation to purchase agricultural products from the US. It explained that the initial $6 billion tranche would be used under the terms of the 2023 agreement to purchase essential goods and medicines.
The remaining frozen assets, however, would not necessarily be limited to humanitarian imports. Tehran could purchase any non-sanctioned goods, officials said, while noting that if US agricultural products proved competitive on price and quality, there would be no obstacle to buying them.
The 2023 agreement was a prisoner-swap and asset-unfreezing agreement between the US and Iran.
Beyond the nuclear issue and the mechanics of sanctions, the agreement’s viability is threatened by regional flashpoints, most notably Lebanon. Ghalibaf insisted that the first real test of the understandings would be the cessation of Israeli attacks on the country.
In response, Vance announced the establishment of a “deconfliction” mechanism involving Washington, Tehran, and Beirut to try to enforce a ceasefire in Lebanon, where Israel has continued to bomb Hizbullah targets.
This mechanism, which reportedly excludes Israel from its monitoring structure, is a direct response to Iran’s demand for an end to fighting on all fronts. Israeli Prime Minister Benjamin Netanyahu has made it clear that Israel is not bound by any US-Iran agreement, a position that introduces a powerful spoiler capable of derailing the talks through renewed military action.
The 60-day timeline, which Vance admits he cannot oversee in person, is very tight for resolving issues that took years to negotiate under the 2015 nuclear deal.
US President Donald Trump’s announcement on Tuesday that his administration would keep all US warships in position to reimpose a blockade on Iran if necessary, that there would be no further negotiations unless Iran agreed to the return of the IAEA inspectors, and that funds released by the Treasury Department regarding Iran would be placed in an escrow account under Washington’s control underscores the hair-trigger nature of this diplomacy.
With technical negotiations moving forward, Washington and Tehran are cautiously constructing what may prove to be the most consequential diplomatic opening since the collapse of the nuclear agreement.
Whether it succeeds remains uncertain. What is already clear, however, is that both governments are behaving less like adversaries seeking victory and more like states recognising the limits of escalation.
