Strait of Hormuz Reopens — Why US Gas Prices May Decrease by Late June

The recent reopening of the Strait of Hormuz, as part of the US-Iran ceasefire agreement announced on June 15, 2026, is anticipated to bring considerable relief to fuel prices at American gas stations by the month's end, as the flow of nearly 20 percent of the world's oil supply resumes. Following the announcement of the agreement, Brent crude oil futures dropped by over 5 percent within hours, with experts predicting a potential further decrease of 8-12 percent if the 60-day negotiation period remains uninterrupted. Since the effective closure of the Strait due to the US-Iran conflict beginning in February 2026, American drivers have faced an increase of approximately $0.60 to more than $1.00 per gallon. However, supply chain experts caution that it could take four to six weeks for fuel prices to fully stabilize due to delays with tankers.
