U.S. March CPI Rises 3.3% Year Over Year, Highest Since May 2024

According to U.S. Labor Department data, March CPI rose 3.3% year over year and core inflation reached 2.6%, with energy and gasoline prices jumping amid reported Strait of Hormuz disruption.

Fact Check
The main numeric claim is supported by the primary source, the Bureau of Labor Statistics. Both Consumer Price Index News Release - March 2026 and Consumer Price Index Summary - March 2026 state that headline CPI rose 3.3% year over year in March 2026 and core CPI rose 2.6% year over year. They also confirm that energy and gasoline prices jumped sharply, with gasoline up 21.2% in March. However, the BLS sources do not support the added causal language about a Strait of Hormuz disruption, and this run did not produce a validated primary source for that attribution. The 'highest since May 2024' portion was also not directly verified from fetched evidence in this run. So the core data are supported, but some contextual framing remains unverified.
