Energy and gasoline drive inflation higher
Energy was the main driver of the monthly increase.
The BLS said the energy index rose 3.9% in May and accounted for more than 60% of the increase in the overall index.
Gasoline prices jumped 7.0% over the month and were up 40.5% from a year earlier. Shelter costs also rose 0.3% in May and were 3.4% higher than a year earlier, while food prices increased 0.2% for the month and 3.1% over 12 months.
Core inflation remains relatively contained
Core inflation, which strips out food and energy, rose 0.2% in May and 2.9% over the past 12 months.
The BLS said that category saw gains in communication, airline fares, medical care, personal care, and recreation, while motor vehicle insurance, household furnishings and operations, and new vehicles were among the areas that fell.
The data eased some market fears that higher energy costs were feeding into broader inflation, with the dollar edging lower after the release.
