The first round of US-Iran negotiations on implementing this week's memorandum, expected on 19 June at the Bürgenstock resort in central Switzerland, will not happen as scheduled, Switzerland's foreign ministry said early Friday. US Vice President JD Vance postponed his travel to Switzerland; Axios reported the delay may be tied to Iranian demands over Lebanon, where the memorandum calls for an end to hostilities but the two sides read the provision differently. Mediators from Pakistan and Qatar had pressed to gather at the Bürgenstock regardless, a measure of how fast the clock is running on a 60-day window.
The mood hardened overnight. The secretariat of Iran's Supreme National Security Council said Tehran would approach the United States with full distrust, monitor implementation closely, and respond to any deviation according to a pre-determined plan. Iran's foreign minister, Abbas Araghchi, set out a two-phase structure: the first round to cover Hormuz, the naval blockade and reconstruction, the harder nuclear and sanctions questions being deferred to a final agreement. US envoy Steve Witkoff told lawmakers Iran would invite the IAEA to inspect its sites and help locate its enriched stockpile, a claim that drew immediate skepticism in Washington.
The memorandum is two days old. The first meeting to implement it is already postponed.
The market kept moving even as the diplomacy stalled. Tankers continued to clear the Strait of Hormuz, building on the seven vessels that transited on Thursday, and Brent held near $78 a barrel, well below the war's $100-plus. The physical reopening of the strait is running ahead of the political settlement meant to guarantee it, which is its own kind of risk: oil is flowing on the strength of an announcement, not a finished deal.
For Central Asia the lesson sits underneath the headlines. The wartime premium that lifted Kazakh and Turkmen oil is fading on the tanker traffic alone, regardless of what happens at the Bürgenstock. But the corridor south through a sanctions-free Iran, the upside CAW flagged on Thursday, depends entirely on the part that just stalled: implementation. A blockade lifted in practice but a deal stuck in negotiation is the worst of both worlds for anyone betting on Iranian transit. Watch whether the talks are rescheduled within days or drift.
