Florida gas prices expected to rise further as Trump issues blockade in Iran

The strait is a key chokepoint for the global oil trade, with 25 percent of seabound oil traversing the endpoint of the Persian Gulf and into open waters in 2025, according to the International Energy Agency.

“At some point, we will reach an ‘ALL BEING ALLOWED TO GO IN, ALL BEING ALLOWED TO GO OUT’ basis, but Iran has not allowed that to happen,” Trump posted Sunday on Truth Social.

Patrick De Haan, head of petroleum analysis at GasBuddy, posted Sunday on Bluesky that without an agreement or terms with Iran, the Strait of Hormuz is likely to remain under Iranian control, “thus gasoline, diesel and jet fuel prices keep rising due to the likely continued closure of the Strait.”

De Haan noted that the per barrel cost of crude oil was back over $100 on U.S. and international markets following Trump’s announcement.

“The rhetoric is back, markets hate uncertainty, just what Trump gave more of,” De Haan added.
