WASHINGTON--U.S. consumer prices rose for the third straight month in April, the latest sign inflation is stabilizing.

The consumer-price index, which reflects what Americans pay for everything from breakfast cereal to medical care, rose a seasonally adjusted 0.1% in April from a month earlier, the Labor Department said Friday. Excluding volatile food and energy categories, so-called core prices climbed 0.3%, the largest increase since January 2013.

Economists surveyed by The Wall Street Journal had expected overall prices to increase 0.1% and core prices to rise 0.2%.

Compared with a year earlier, overall prices actually fell 0.2% and core prices rose 1.8%.

The consumer price index, like most measures of inflation, began falling fairly steadily in the middle of last year. The decline largely reflected the tumbling cost of a barrel of crude oil, which topped $100 over the summer but then dropped below $50 earlier this year. Prices have since firmed near $60.

The stronger dollar also has kept prices in check by holding down the cost of imported goods and services.

The Federal Reserve is closely tracking inflation as it considers when to lift interest rates from near zero, where they have held since December 2008. The central bank's preferred inflation gauge, the price index for personal consumption expenditures, has undershot a 2% target for nearly three years.

While inflation is expected to remain below 2% in the short term, Fed officials at their April policy meeting said they expect it to gradually rise "as the labor market improved further and the transitory effects of declines in energy prices and non-energy import prices dissipated," according to minutes released earlier this week.

Still, officials said they are unlikely to have enough information to start raising rates at their next meeting in June. Low rates are meant to spur hiring and investment, and officials at the central bank want to be sure the economy is on firm footing before they make their first move.

Friday's report showed energy prices dropped 1.3% from March, with the gasoline index sliding 1.7%.

Food prices were unchanged from the prior month.

The change in core prices was driven by rising costs for housing, medical care, furniture and vehicles. Clothing and airfare prices declined, Friday's report said.
