US consumer prices rose 3.8% year-over-year in April 2026, the highest annual inflation reading since May 2023, according to Bureau of Labor Statistics data released on Tuesday, as surging energy costs driven by the ongoing conflict with Iran pushed the cost of living sharply higher across the economy.
The Consumer Price Index rose 0.6% on a monthly basis, in line with economist expectations, but the annual figure came in 0.1 percentage points above the Dow Jones consensus estimate of 3.7%, extending a trend of above-target inflation that is complicating the Federal Reserve’s rate path.
Energy prices were the dominant driver, accounting for more than 40% of the total CPI increase in April, with the energy index up 3.8% for the month and 17.9% over the past year as the war’s disruption of Middle Eastern oil supplies has effectively closed the Strait of Hormuz to normal shipping traffic.
Gasoline prices surged 5.4% in April alone and are up 28.4% from a year earlier, with national average prices reaching $4.50 per gallon according to AAA, up from approximately $3.14 a year ago, representing a roughly 50% increase since the conflict began on February 28.
Airline fares rose 2.8% in the month and are up 20.7% year-over-year, reflecting the direct pass-through of elevated jet fuel costs to travellers, with economists noting that fuel surcharge provisions built into transportation contracts mean oil price increases take time to fully ripple through.
Beyond energy, inflation pressures also emerged from shelter costs, which rose 0.6% after easing in prior months, tariff-sensitive apparel, which increased 0.6%, and household furnishings and operations, which rose 0.7%, indicating that the inflationary impulse is broadening beyond war-driven energy costs alone.
Core prices, which exclude volatile food and energy components, rose 0.4% for the month and 2.8% year-over-year, keeping underlying inflation well above the Federal Reserve’s 2% target even after stripping out the most dramatic price spikes.
Real average hourly wages fell 0.5% for the month and declined 0.3% annually in the worst news for workers in the report, as nominal wage growth failed to keep pace with price increases, effectively eroding purchasing power for millions of US households.
Federal Reserve incoming Chair Kevin Warsh, recently nominated by President Trump, has advocated for lower interest rates, a position analysts note will be increasingly difficult to square with an inflationary environment pushed higher by the Iran war, with one investment officer warning that rate hikes could be back on the table for 2026.
Edward Jones senior economist James McCann described American households as continuing to feel the brunt of surging energy costs, warning that with the Strait of Hormuz still effectively shuttered, the risk that inflation has not yet peaked is rising.
