US inflation surges to 3.8% in April as Iran war drives energy prices higher

US consumer prices rose 3.8% in April 2026, the highest rate in nearly three years, driven by surging energy costs from the ongoing US-Israel war on Iran.

Iran's blockage of the Strait of Hormuz disrupted global oil and gas supplies, pushing up gasoline, grocery, and fuel prices across the country.

This spike complicates Federal Reserve policy amid economic uncertainty with broad effects on households worldwide.

  • The Strait of Hormuz handles about 21 million barrels of oil daily, making even brief disruptions capable of triggering global price shocks.
  • Inflation above 3% typically prompts the Federal Reserve to consider rate hikes, which increase borrowing costs for mortgages, auto loans, and credit cards.

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
