U.S.-Iran negotiations begin in Switzerland to seek permanent end to war
U.S.-Iran negotiations in Switzerland aim to swiftly end hostilities within 60 days, focusing on nuclear limits, sanctions relief and Strait of Hormuz access.
The United States and Iran opened direct talks in Switzerland on Sunday in an effort to secure a permanent end to their conflict within 60 days, with the nuclear file at the centre of the agenda. U.S.-Iran negotiations are now addressing sanctions relief, frozen assets and a proposed $300 billion reconstruction fund, even as officials warn the Israel–Hezbollah fighting in Lebanon could derail progress. Diplomats said the sessions will attempt to sequence concessions to reduce the risk of sudden collapse.
Negotiations Open in Switzerland
The negotiations follow a preliminary framework signed last week that set a tight timetable and a broad set of priorities for both sides. Delegations are meeting in neutral territory with a mandate to convert the framework into a comprehensive agreement within the two-month window.
Officials described an intensive schedule of technical and political talks that will move between plenary sessions and working groups focused on nuclear constraints, financial measures and regional security. Observers noted that the talks’ success will depend heavily on manageable sequencing and the willingness of external actors to support implementation.
Sanctions Relief and Frozen Assets
One of the most contentious issues is the immediate unfreezing of Iranian assets held abroad and the rollback of U.S. sanctions, which Tehran says are vital for stabilising its battered economy. The preliminary deal allows for a rapid review of asset transfers, but Washington has indicated that relief may be conditioned on verifiable commitments.
President Trump has said sanctions will be lifted “as soon as they behave,” while U.S. officials see financial relief as powerful leverage to secure broader Iranian concessions. Andreas Krieg, a Middle East security expert at King’s College London, told reporters the core dispute is the order of moves — who will act first and how much will be released at each stage.
Reconstruction Fund Debate
The draft framework also referenced a proposed $300 billion reconstruction fund to help rebuild parts of Iran damaged by the conflict, but the composition and governance of that fund remain unresolved. The U.S. has said it will help design the mechanism while making clear that Washington would not itself be a financier of the entire package.
A diplomat familiar with the talks said the fund is envisioned as a conduit for private and state-backed investment rather than direct U.S. government payouts, and that global firms and governments have already signalled partial commitments. The political sensitivity of such a fund is acute in the United States, where memories of past cash transfers and domestic opposition complicate any visible role for the U.S. Treasury.
Strait of Hormuz and Maritime Transit
Maritime access through the Strait of Hormuz is on the table, with the preliminary agreement committing Tehran not to charge passage fees for at least 60 days. Beyond that temporary moratorium, Iran’s foreign ministry has signalled the possibility of levying fees in exchange for unspecified services, a proposal that Washington has publicly opposed.
The strait’s status will also be discussed in parallel talks that could include Oman and other regional states, diplomats said, reflecting the waterway’s outsized importance for global oil and gas flows. Analysts warn that even the threat of fees or transit restrictions gives Tehran a potent bargaining chip to extract concessions elsewhere, particularly on frozen assets held in neighbouring banks.
Ballistic Missile Program
U.S. demands to curb Iran’s short-range ballistic missile capability — a key Israeli concern — will be difficult to translate into strict limits, officials and experts say. Early wartime assessments found Iran still retained a large share of its mobile launchers, and American policymakers have recently signalled a softer posture on immediate, hard caps.
Vice President JD Vance asserted that U.S. operations had left Iran’s missile capacity “substantially degraded,” while President Trump has accepted that some missile capability may persist. King’s College’s Andreas Krieg suggested any language on missiles in a final accord would likely be loose and monitoring-lite, noting that conventional missile limits are atypical outside total surrender scenarios.
Timeline, Risks and Next Steps
Delegates enter the talks aware that the 60-day target increases political pressure but also compresses time for complex technical work and trust-building. Negotiators will need to thread sensitive sequencing: who provides financial relief first, how reconstruction funds are governed, and what guarantees of maritime freedom can withstand domestic politics on all sides.
The risk of external shocks — notably escalations in Lebanon between Israel and Hezbollah — looms over the Swiss sessions and could prompt rapid re-evaluation of commitments. Diplomats said contingency mechanisms and incremental verification steps will be key to keeping the talks on course.
If negotiators can agree clear benchmarks and a credible verification regime within the set timeframe, the preliminary framework could be converted into a broader settlement that addresses nuclear constraints, economic reopening and regional stability.
