JD Vance reversed his cancelled trip and met Iran's delegation in Switzerland on 21 June, the first direct talks since the Islamabad MOU. The IRGC closed the Strait of Hormuz again a day earlier, routing all traffic through Oman's waters. Five days after Trump declared the war over, the binding facts are being set by other hands.
Iran's corps and PGSA are writing Hormuz's operative rules; Washington is producing declarations.
JD Vance flew to Switzerland on 21 June and sat across from Iran's Ghalibaf and Araghchi, two days after a wire report said he had cancelled the trip and Iran had pulled its negotiators.
QatarJD Vance flew to Geneva on 21 June and met Iran's parliament speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi. Pakistan's army chief Asim Munir and Qatar co-mediated. Al Jazeera reported the first round concluded the same day.
The meeting reversed Vance's cancellation two days earlier, after Iran's military closed the strait of Hormuz on 20 June. Iran's escalation appears to have forced Washington back to the table rather than away from it.
The IRGC's Khatam al-Anbia command declared the Strait of Hormuz closed on 20 June, its second such order of the war. CENTCOM rejected it within hours.
IranIran's IRGC (Islamic Revolutionary Guard Corps) declared the strait of Hormuz closed on 20 June. Khatam al-Anbia HQ cited Israeli strikes in Lebanon as a breach of the Islamabad peace deal and ordered all shipping to stay clear. US Central Command rejected the order. 55 ships carried 17 million barrels through the strait the same day.
This was the second IRGC closure in ten days. Oil markets discounted both. The Oman territorial waters corridor kept barrels moving regardless.
A US-led naval advisory on 20 June flagged mines in Hormuz's standard lanes and cleared one route through Oman's territorial waters. All 55 ships that transited that day used it.
United StatesA US-led naval body warned on 20 June that the standard Hormuz shipping lanes may contain mines. It cleared a safer route through Oman's coastal waters. US Central Command reported 55 ships carrying 17 million barrels used that Omani route the same day.
This shifts effective control of the world's main oil chokepoint into Omani territorial waters. Oman, mediating between the US and Iran, now holds the operative key to Hormuz traffic.
Iran's Persian Gulf Strait Authority made insurance compulsory on every Hormuz transit on 20 June, free for now, with fees reserved for after the MOU's 60-day window closes around 17 August.
United KingdomIran's Persian Gulf Strait Authority made insurance compulsory on all Hormuz transits on 20 June, currently free, with fees reserved from August 2026. The authority is on the US sanctions list: buying its insurance exposes shipping companies to US penalties.
Most ships are avoiding the problem by using Oman's waters, which sit outside the authority's jurisdiction. August is Iran's deadline lever: no final deal means fees start on the only lane it can reach.
Israeli forces killed at least 20 people in south Lebanon on 20 June and 16 more on 21 June, hours after a renewed ceasefire collapsed. Netanyahu and Katz ordered the IDF to hold its positions.
IsraelA Lebanon ceasefire renewed on 19 June collapsed within hours. Israeli forces killed at least 20 people on 20 June and 16 more on 21 June. Prime Minister Netanyahu ordered the Israel Defense Forces to hold positions in southern Lebanon.
Israel never signed the Iran-US peace deal. Its Lebanon operations cannot be controlled by that agreement. Iran's military has used these Israeli strikes as the legal pretext for two Strait of Hormuz closure declarations.
OFAC designated a Muscat financial firm on 18 June for Hezbollah links, and through 21 June issued no Iran general licence and delisted no Iranian entity. The MOU promised relief within 48 hours.
OFAC (the US sanctions office) had issued no relief for Iran by 21 June. This was five days after the Islamabad peace deal required waivers for Iranian crude exports 'immediately upon signing'. On 18 June OFAC instead designated a Hezbollah-linked company in Oman, the opposite of relief.
Washington fulfilled only its cheapest commitment: ending naval blockade enforcement. Oil-transaction waivers and delisting actions, both due within 48 hours of signing, have not arrived.
Brent crude settled near $80.59 on 19 June and barely moved when the IRGC declared Hormuz shut the next day. It is the second closure this month that markets have priced as theatre.
Brent Crude settled near $80.59 on Friday 19 June. When Iran's military declared Hormuz closed on Saturday, markets barely moved. The first closure on 11 June saw Brent fall from $96.34 to $89.25 by 12 June as traders priced it as leverage.
Oil markets are pricing the Oman route over Iran's words. 55 ships carrying 17 million barrels used Omani waters on 20 June; the closure declaration produced no supply shock because barrels kept flowing.
Direction is sideways-to-up. The Geneva round on 21 June is a de-escalatory signal, but it was unlocked by the IRGC's 20 June Hormuz closure, the second in ten days. That pattern, corps escalates, diplomats negotiate, prices the next session at the cost of a military move. The concrete tipping mechanism is the PGSA's 17 August fee deadline: if OFAC has not issued an oil-transaction waiver by that date, the PGSA switches on fees for the only operating lane, pushing shippers into the sanctioned-insurer trap and returning Brent toward the $96 peak of 10 June 2026. The named decision point is OFAC: a general licence for Iranian crude issued before a second Geneva round breaks the escalation pattern; the White House Presidential Actions register carrying nothing by 1 August confirms the corps retains the initiative.
