US and Iran Sign Agreement to End War, Reopen Strait of Hormuz and Extend Ceasefire
BLUFFormal signing by June 20 is likely, but mine-clearing timelines and deferred nuclear talks mean commercial and strategic normalization remains months away.
The US and Iran on Monday announced an initial memorandum of understanding to end the war, reopen the Strait of Hormuz, and halt fighting on all fronts, with a formal signing ceremony set for Switzerland on Friday 123. VP Vance and a senior US official told reporters both sides had already signed the document digitally on Sunday, but Iran had not confirmed that Parliament Speaker Mohammad Bagher Ghalibaf had signed 2. A US military advisory stated the naval blockade of Iranian ports would remain in effect until Friday while Trump wrote on Truth Social that ships were "starting to move" through the strait 2. Harder issues including Iran's nuclear program, sanctions, and proxy relationships were deferred to a 60-day negotiation period following the formal MoU signing 23.
AnalysisIran's silence on the digital signature and its foreign ministry's insistence on transit fees signal more friction than Washington's framing suggests, but the formal signing
likely proceeds by June 20, as the political cost of collapse now exceeds that of proceeding for both capitals. High confidence rests on converging public commitments from both governments, though the toll divergence between Vance's toll-free commitment and Tehran's fee demand may indicate Iran signed with strait administration terms still open, creating conditions for the ceremony to collapse or slip. All reporting draws exclusively from official statements, leaving the MoU text unverified by any independent channel. Mine-sweeping requires 40 to 50 days before major insurers permit transit, meaning shipping companies and energy insurers must weigh whether to begin re-entry planning ahead of Friday or hold for confirmed text and mine-clearance certification.
