US-Iran Negotiations in Switzerland - Strait of Hormuz Closure Impact on Global Energy | Langit Eastern
Direct negotiations between the United States and Iran commenced in Switzerland on Sunday, June 21, 2026, amid renewed tensions following the Islamic Revolution Guard Corps (IRGC) announcement that it had closed the Strait of Hormuz. This action was taken in response to Israeli air strikes in southern Lebanon, which Iran claims violates the first clause of the previously signed 14-point memorandum of understanding. The clause requires the immediate and permanent cessation of military operations on all fronts, including in Lebanon.
US Vice-President JD Vance arrived in Switzerland early Sunday morning to lead the American delegation. The Iranian delegation, including parliamentary speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, arrived late Saturday. Pakistan has also joined the negotiations, with Prime Minister Shehbaz Sharif and Chief of Army Staff Field Marshal Asim Munir participating as mediators. Pakistan's Ministry of Foreign Affairs stated that Pakistan will continue to support the implementation of understandings between Iran and the United States.
A direct contradiction has emerged between Iran's statement and the US military's assessment. US Central Command (Centcom) spokesperson Tim Hawkins stated that traffic continues to flow through the strait and that Iran does not control the Strait of Hormuz. Centcom reported that 55 merchant ships transited the strait on Saturday carrying more than 17 million barrels of oil for global markets. This data suggests that Iran's closure claim may be more political than operational in nature.
The economic stakes are enormous. The Strait of Hormuz serves as a transit chokepoint for approximately 20 million barrels of oil and oil products per day, representing nearly 600 billion US dollars worth of annual energy trade. Any disruption to this waterway could trigger a sharp spike in global oil prices and disrupt energy supply chains to major consumer nations including China, Japan, India, and South Korea.
Vance expressed hope for progress on the nuclear issue and the Lebanon ceasefire. However, the situation on the ground remains volatile. On Saturday, at least 47 people were killed in Lebanon following Israeli air strikes. The IDF claimed to have struck 80 Hezbollah-linked targets and killed dozens of its members. Hezbollah accused Israeli attacks in Lebanon of being an attempt to sabotage the broader US-Iran deal.
