WASHINGTON: Consumer inflation posted a surprise acceleration in February, US government data showed Tuesday, a development that could give policymakers pause as they mull the right time to start interest rate cuts.

While price increases have fallen from their peak in 2022, households are still feeling the pinch from costs of living, adding pressure on US President Joe Biden as he seeks reelection this year.

The annual consumer price index (CPI) came in at 3.2 percent last month, the Labor Department said on Tuesday, a sign that these stresses may not ease quickly.

The “core” measure stripping out volatile food and energy prices edged down slightly to 3.8 percent, but came in above the 3.7 percent analysts expected.

The Labor Department noted that the indexes for shelter and gasoline both rose in February.

Combined, they contributed more than 60 percent of the monthly increase for the overall index, it said.

From January to February, inflation rose 0.4 percent, ticking up from the prior month as well.

Analysts expect the Federal Reserve to focus on underlying inflation when deciding the best time to start reducing rates.

To curb stubborn price increases, the central bank embarked on a series of rapid interest rate hikes in 2022, before holding the level at its highest in more than two decades at recent meetings.
