Talks between the US and Iran in Switzerland on a permanent peace deal began on June 21, 2026, aimed at resolving Iran's nuclear program and permanently reopening the Strait of Hormuz. US Vice President JD Vance was present for these negotiations, which included mediation from Pakistan and Qatar. The discussions were expected to be protracted, covering topics such as Iran's nuclear capabilities and economic relief for Tehran. An interim deal had previously signaled a pause in hostilities, but the formal peace talks were anticipated to be just the beginning of a complex process. Key issues on the agenda included the Strait of Hormuz, US sanctions, and the return of frozen Iranian assets. Initial reports from Iranian media suggested talks had halted due to new threats from President Donald Trump regarding Hezbollah's actions in Lebanon, though US sources indicated negotiations were continuing.
The discussions were complicated by Iran's earlier announcement on Saturday, June 20, that it would close the Strait of Hormuz again, despite an increase in commercial shipping traffic through the waterway. This threat, coupled with Trump's renewed warnings of strikes if Hezbollah continued its attacks, introduced significant uncertainty. While oil continued to flow through the strait in the immediate aftermath of Iran's statement, the situation created nervousness in the oil markets. The US-Iran memorandum that led to these talks had previously seen Washington lift a naval blockade and promise to waive sanctions on Iranian crude, with Iran pledging to reopen the Strait of Hormuz, which is vital for approximately one-fifth of the world's oil and gas supplies. However, Iran's condition that ships would need its permission and mandatory insurance to cross was met with disapproval by the US, Europe, and Gulf Arab states.
Oil prices reacted to the shifting geopolitical landscape. On Friday, June 19, oil prices rose as the prospect of a lasting truce between the US and Iran became clouded by renewed uncertainties and Israel's continued attacks on Lebanon. Brent crude futures gained $0.51, or 0.64%, to $80.36 a barrel, while US West Texas Intermediate crude rose $1.28, or 1.7%, to $77.88 a barrel. Both contracts were still heading for a weekly loss of about 8%. The more actively traded WTI August contract was up $0.05 a barrel. Adding to the market's unease, Vice President JD Vance pulled out of a planned trip to meet Iranian negotiators in Switzerland on Friday, further diminishing confidence in the peace process. Analysts noted that traders were awaiting concrete evidence of normalized tanker traffic through the Strait of Hormuz before committing to further price movements, despite expectations that the deal would release over 85 million barrels of oil into global markets and lift US sanctions on Iranian oil.
