The 60-day negotiation period established between the United States and Iran officially began on June 18, 2026. Vice President JD Vance characterized the window as a critical transition toward a potential long-term peace deal focused on Iran’s nuclear program. As part of the immediate de-escalation, U.S. Central Command confirmed it has lifted the blockade on Iranian ports, allowing approximately 12.5 million barrels of oil to transit the Strait of Hormuz overnight. Despite the opening of sea lanes, the Trump administration has maintained a firm stance. Defense Secretary Pete Hegseth issued a public warning stating that the U.S. military remains postured to resume operations and reimpose an 'ironclad blockade' should Tehran violate the Memorandum of Understanding (MOU). Simultaneously, the White House formalised the process by delivering the interim agreement to Congress for review. Conflicting visions for the future of the region have already emerged. While Qatar’s Foreign Ministry praised the deal as a 'solid foundation' for upcoming technical talks in Switzerland, Iranian negotiator Mohammad Baqer Ghalibaf signaled that the Strait of Hormuz will not return to pre-war norms. Ghalibaf stated that Tehran intends to begin charging transit fees for maritime traffic once the 60-day fee-free period expires, indicating potential friction even if kinetic hostilities remain paused.
