US Inflation Accelerates, Tempering Case for Fed to Cut Rates

US inflation accelerated in December as Americans paid more for housing and driving, challenging investor bets that the Federal Reserve will cut interest rates soon.

The consumer price index increased 3.4% in the year through December, the most in three months according to government figures. On a monthly basis, it also rose by more than forecast.

The CPI excluding food and energy rose 0.3% in December from a month earlier. On an annual basis, the so-called core measure increased 3.9%. Economists favor the core metric as a better gauge of the trend in inflation than the overall CPI.

Metric Actual Estimate
CPI MoM +0.3% +0.2%
Core CPI MoM +0.3% +0.3%
CPI YoY +3.4% +3.2%
Core CPI YoY +3.9% +3.8%

The Bureau of Labor Statistics figures showed increases in shelter, electricity and motor-vehicle insurance. Used-car prices increased for a second month, defying expectations for a decline.

Despite the pickup, the figures cap a year in which inflation broadly eased without doing much damage to the labor market, setting the stage for the Fed to lower borrowing costs this year.
