How an Iran Escalation Could Hit Gas Prices

President Trump is weighing military action against Iran, a major oil producer that controls a critical global shipping lane. Markets are already reacting, and the political stakes are rising.

President Donald Trump is considering whether the United States should attack Iran, a country with the world’s third-largest proven oil reserves and control over the Strait of Hormuz. Oil prices have climbed sharply as US military activity in the region increases and markets price in potential disruption.

Brent crude has surged 7% since Tuesday and moved above $70 a barrel for the first time since July. US crude has gained $10 over the past month, reflecting growing concern about supply risks.

“A prolonged disruption in the Strait of Hormuz would send oil above $100,” said Rob Thummel, a senior portfolio manager at Tortoise Capital.

The Strait of Hormuz carries roughly 20 million barrels of crude per day, about one-fifth of global supply. Iran partially closed the strait for military drills earlier this week, briefly pushing Brent about $5 higher.

While a full blockade remains unlikely, even limited disruption could lift oil toward $80 a barrel and push US gas prices back above $3 a gallon. Gasoline recently averaged $2.92, up from $2.80 a month ago.

Why This Matters

  • Energy prices directly affect household budgets and consumer confidence.
  • Affordability concerns have left Republicans politically exposed ahead of midterms.
  • Iran accounts for roughly 4% of global crude production despite heavy sanctions.

What’s Next

  • Markets will closely track US military movements and diplomatic signals over the coming days.
  • Oil traders will monitor any restrictions in the Strait of Hormuz.
  • Gasoline prices could rise further if crude extends recent gains.
