ABC News Launches Gas Calculator as U.S. Prices Swing Between $3.79 and $4.50

Q: With a fragile U.S.-Iran deal, what could trigger another crippling surge in global gas prices for drivers?

The biggest trigger would be any renewed disruption of the Strait of Hormuz. The waterway carries roughly a fifth of global oil and gas flows, and earlier fighting, tanker attacks, mines and blockades there helped push crude above $100 a barrel and U.S. gasoline to about $4.50 a gallon. If shipping is again choked off, even briefly, traders would likely add a sharp geopolitical premium and pump prices could jump quickly. That risk is tied directly to the fragility of the U.S.-Iran arrangement. The ceasefire is shaky, permanent peace talks have stalled, and recent tit-for-tat strikes show how easily the situation could slide back into open conflict. Any collapse of the deal, renewed U.S. naval restrictions, or Iranian moves to impede passage, impose fees, or threaten exports through the Gulf would tighten supply and rattle markets. Another trigger is failure to resolve the core disputes left for later, especially Iran’s nuclear program and sanctions relief. Analysts cited in the broader coverage say the current understanding is only an interim framework, with the hardest issues deferred. If talks break down, sanctions snap back, or Iran’s oil exports are curtailed again, global supply would shrink and prices would rise. Experts also note that markets have already priced in some hope of de-escalation. That means the next surge could come not only from actual supply losses, but from proof that the Strait is not truly secure or that the diplomatic opening is collapsing.
