Iran Uses Hormuz Threat as Leverage While Heading to Swiss Talks With U.S.
Even as Iran’s military warns ships away from the Strait of Hormuz, a high‑ranking Iranian delegation is flying to Switzerland for technical talks on an interim deal with U.S. envoys. The parallel tracks turn the world’s key oil chokepoint into a negotiating tool over Lebanon, sanctions waivers, and frozen funds, putting diplomats, energy planners, and regional allies on notice that coercion and diplomacy are now running in tandem.
Iran is pairing a high‑stakes threat to global shipping with a renewed round of diplomacy, sending senior officials to Switzerland for technical talks with the United States even as its military command tells commercial vessels to stay away from the Strait of Hormuz. The dual track underlines how Tehran is trying to convert military risk and regional conflict into bargaining power over sanctions relief and the war in Lebanon.
Pakistan’s foreign ministry announced that “technical‑level” negotiations between the U.S. and Iran would resume on Sunday, 21 June, in Bürgenstock, Switzerland, as part of follow‑up on an interim understanding between the two countries. A separate statement from Iran’s Foreign Ministry said an Iranian delegation would depart for Switzerland despite the declared closure of the Strait of Hormuz, explicitly describing the talks as a venue to address U.S. commitments.
Iranian state media have now confirmed that the delegation is both larger and more senior than many expected. It is led by parliament speaker Mohammad Baqer Qalibaf, joined by Foreign Minister Abbas Araghchi, a deputy head of Iran’s Supreme National Security Council, the central bank governor, and other senior foreign‑policy and security officials. On the U.S. side, envoys are already in Switzerland, with one American political figure, JD Vance, expected to travel there as preparations continue, according to U.S. media reports.
Tehran’s message heading into the talks is sharpened by its handling of Hormuz. Iran’s IRGC Navy has warned that the Strait is “closed” and that vessels should not approach, saying their security would be at risk if they ignore the warning. The Khatam al‑Anbiya Central Headquarters has framed the closure as a response to “blatant” U.S. violations of a war‑ending agreement and to ongoing Israeli operations and non‑withdrawal from southern Lebanon. Foreign Ministry spokesperson Esmail Baghaei has argued that the first clause of the memorandum of understanding — “ending the war on all fronts, including in Lebanon” — is the most important pillar of the mutual commitments, and that by failing to rein in Israel, the U.S. has breached the deal.
Iran is also raising the bar for what it considers a satisfactory outcome in Lebanon. According to sources familiar with its position, Tehran is not only demanding a ceasefire but a full withdrawal of Israeli forces from southern Lebanon before final negotiations are concluded. Israeli officials reject the narrative that they are violating the ceasefire, with Israel’s ambassador to Washington publicly insisting that Hezbollah is the party breaking the truce and accusing Iran of using its proxy “to extort concessions.” The rhetorical clash sets the stage for hard bargaining in Switzerland, where U.S. negotiators will have to reconcile their regional commitments with the need to keep Iran from escalating further at sea or via proxies.
The talks will also touch on economic levers that matter to Tehran’s domestic and regional agenda: the pace of implementing sanctions waivers, the status of still‑pending releases of Iranian funds held abroad, and technical mechanisms intended to ease some of Iran’s financial isolation without triggering full‑scale political backlash in Washington. For Iran’s leadership, the ability to threaten disruption in Hormuz while sitting at the table with U.S. envoys is a way to remind counterparts that it retains tools capable of hurting global markets if its demands are ignored.
For energy planners and regional allies, the symmetry is uncomfortable. The same Iranian system that sends its parliament speaker and foreign minister to negotiate is allowing its elite military units to declare one of the world’s most important sea lanes off‑limits. Even if actual tanker traffic continues, as U.S. Central Command insists, the perception of risk can move premiums, influence hedging decisions, and alter the tone of the talks themselves. Diplomats will have to calculate whether concessions on Lebanon or sanctions enforcement are more or less costly than the possibility of an enforced Hormuz disruption.
Iran’s strategy also speaks to a broader lesson in modern coercive diplomacy: a state does not need to fire a shot to weaponize a chokepoint. Public statements, credible military deployments, and a clear linkage to negotiation demands can be enough to change the behavior of corporations and other governments — especially when memories of past tanker seizures in the Gulf are still fresh.
The Swiss meetings will be watched for concrete signs of de‑escalation or hardening positions. Key indicators include whether Iran softens its language on Hormuz during or after the talks; whether the U.S. and European partners offer any adjustments on sanctions waivers or frozen assets; and whether the tempo of Israeli operations in Lebanon shifts in ways that might give Iranian officials cover to step back from their most aggressive threats. The outcome will not only affect Lebanon and nuclear diplomacy, but also whether Hormuz remains a background anxiety — or becomes an active front in the confrontation.
