The consumer price index, a broad measure of goods and services costs across the U.S. economy, fell a seasonally adjusted 0.1% in March, putting the 12-month inflation rate at 2.4%, down from 2.8% in February.
Excluding food and energy, so-called core inflation ran at a 2.8% annual rate, having increased 0.1% for the month. That was the lowest rate for core inflation since March 2021.
Slumping energy prices helped keep inflation tame, as a 6.3% drop in gasoline prices helped drive a 2.4% broader decline in the energy index. Food prices climbed 0.4% on the month.
Moreover, shelter prices, among the most stubborn components of inflation, increased just 0.2% in March and were up 4% on a 12-month basis, the smallest gain since November 2021. Used vehicle prices were off 0.7% while new vehicle costs increased just 0.1%, ahead of tariffs that are expected to hit the auto industry hard.
