US inflation rose at fastest pace in three years in April as Iran war hikes up prices

• Energy prices jumped 5.5% monthly in April due to Iran war disruptions in the Strait of Hormuz; gasoline prices alone rose 12.3% that month and over 50% since the conflict started
• Real household disposable income fell for the third consecutive month as inflation outpaced wage gains, with the savings rate dropping to 2.6%, the lowest since June 2022
• First quarter GDP growth was revised down to 1.6% from 2.0%, with consumer spending also downgraded to 1.4% as economists expect further pullback amid depleted savings and economic uncertainty

Summary

Key Facts and Figures

U.S. inflation accelerated to its fastest pace in three years in April 2026, with the Personal Consumption Expenditures (PCE) price index rising 3.8% year-over-year, up from 3.5% in March. Core PCE inflation increased 3.3% annually. The monthly PCE index rose 0.4% in April.

Primary Drivers

The surge is attributed to the Iran war, which disrupted shipping through the Strait of Hormuz. Gasoline prices jumped 12.3% in April alone and have risen over 50% since the conflict began in late February. Energy prices surged 5.5%, while food prices rebounded 0.5%. Pre-existing inflation was already elevated due to Trump administration tariffs.

Economic Impact

First-quarter GDP growth was revised down to 1.6% from 2.0%, with consumer spending growth lowered to 1.4% from 1.6%. Real disposable income declined for the third consecutive month in April, dropping 0.5%. The household savings rate fell to 2.6%, the lowest since June 2022.

Market Implications

Financial markets expect the Federal Reserve to maintain interest rates in the 3.50%-3.75% range into 2027. Some policymakers are considering rate hikes despite White House pressure for cuts. New Fed Chair Kevin Warsh faces challenges balancing political pressure with inflation control.

Political Ramifications

President Trump's approval rating has fallen to near-record lows, particularly among Republicans, threatening the GOP's congressional majority in November midterm elections. Trump won the 2024 election largely on promises to reduce inflation.
