Fuel prices are on the rise following the resumption of conflict over the Strait of Hormuz on July 14. The U.S. launched two new attacks on Iran, and the blockade of the strait is expected to restart. Shipping tolls are another potential risk. 

This violence over a major route for oil and gas followed Iran’s parliament ruling that its ceasefire with the U.S. was over. They claim that the U.S. violated the memorandum of understanding between the two countries. Iran likely plans to retaliate and seek administrative control of the strait.

Meanwhile, Democratic lawmakers in the U.S. are split over U.S. aid to Israel. Representative Hakeem Jeffries of New York “plans to oppose a measure that would eliminate United States aid to Israel,” according to the New York Times. The House of Representatives could vote on this measure as early as July 15. 

Aid from the U.S. to Israel led to the Iran war and the battle over the Strait of Hormuz. Removing aid could end the conflict in Iran’s favor, while allowing aid to continue could cause this to drag on more than it already has. Either way, it’s unlikely that fuel prices will stabilize in the remainder of 2026.
