US inflation accelerated in March 2026, with the Consumer Price Index (CPI) rising 0.9% for the month and 3.3% year-over-year, reports the Bureau of Labor Statistics. The increase was driven by a spike in energy prices, especially gasoline, which rose by more than 21% and accounted for most of the monthly gain.

Core inflation (excluding food and energy) remained relatively moderate, rising 0.2% in March and 2.6% annually, while food prices were flat overall, with grocery prices slightly declining. Despite some easing in categories like medical care and used cars, rising costs in shelter, transportation, and energy continue to put upward pressure on overall inflation. The BLS writes:

The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.9 percent on a seasonally adjusted basis in March, after rising 0.3 percent in February, the U.S. Bureau of Labor Statistics reported today. Over the last 12 months, the all items index increased 3.3 percent before seasonal adjustment.

The index for energy rose 10.9 percent in March, led by a 21.2-percent increase in the index for gasoline, which accounted for nearly three quarters of the monthly all items increase. The shelter index also increased in March, rising 0.3 percent. The index for food was unchanged over the month as the index for food away from home rose 0.2 percent, while the index for food at home fell 0.2 percent.

The index for all items less food and energy rose 0.2 percent in March. Indexes that increased over the month include airline fares, apparel, household furnishings and operations, education, and new vehicles. Conversely, the indexes for medical care, personal care, and used cars and trucks were among the major indexes that decreased in March.

The all items index rose 3.3 percent for the 12 months ending March, after rising 2.4 percent for the 12 months ending February. The all items less food and energy index rose 2.6 percent over the year, following a 2.5-percent increase over the 12 months ending February.
