US Vice President JD Vance kicked off direct US-Iran talks at Switzerland's Bürgenstock resort on Sunday, implementing a 14-point memorandum signed June 17 that set a 60-day ceasefire to end a war that erupted February 28. The talks aim to reopen the Strait of Hormuz, a chokepoint for about a fifth of global oil supply. Markets have been watching closely — oil fell sharply after the deal, but Bitcoin barely budged.
How the talks came together
The June 17 memo was signed by President Donald Trump and Iranian President Masoud Pezeshkian. It established a 60-day ceasefire and a framework for negotiations. Iran had suspended talks on Friday over Israeli strikes in Lebanon, then agreed to meet on Sunday. Pakistan and Qatar are mediating in a four-way format alongside the US and Iran. Vance leads the US side; Iranian chief negotiator Mohammad Bagher Ghalibaf leads Tehran's team.
What each side wants
Washington wants fast movement on Iran's nuclear program. Tehran wants fighting in Lebanon to stop first, plus sanctions relief, unfreezing of assets, and an end to the US naval blockade. The two demands are in tension: the US sees nuclear progress as a prerequisite; Iran sees it as a reward. Israeli strikes killed dozens in Lebanon over the weekend, and five Israeli soldiers have died since the ceasefire deal. Trump escalated on Truth Social, warning Iran over its Lebanese proxies and threatening to hit Iran very hard again.
Oil and markets weigh in
After the signing, oil fell sharply and equities set records. Brent crude slipped to about $78 a barrel, and US gas hit $3.99 a gallon — its lowest since March. GasBuddy analyst Patrick De Haan expects sub-$3 gas by early 2027 if the truce holds. The Strait of Hormuz sees about 20 million barrels of oil daily. Iran's Revolutionary Guard declared it shut on Saturday citing Israel's attacks, but US Central Command said 55 tankers still passed that day, carrying more than 17 million barrels. Bitcoin barely reacted, holding near $64,000. Last June, a similar Iran ceasefire sent it above $105,000.
The battlefield test
Israel's strikes in Lebanon over the weekend killed dozens, and five Israeli soldiers have died since the deal. Iran suspended talks Friday, then agreed to meet Sunday. Trump's Truth Social posts added heat. The fighting in Lebanon is the most immediate threat to the ceasefire — if it doesn't stop, Tehran could walk away again. For now, the talks are on, but the next few days will test whether the ceasefire survives in Lebanon.
