US CPI Rises More Than Forecast, Stalling Inflation Progress

Underlying US inflation rose more than forecast in September, representing a pause in the recent progress toward moderating price pressures.

The so-called core consumer price index — which excludes food and energy costs — increased 0.3% for a second month, disrupting a string of lower readings, Bureau of Labor Statistics figures showed Thursday. The three-month annualized rate advanced 3.1%, the most since May, according to Bloomberg calculations.

Economists see the core gauge as a better indicator of underlying inflation than the overall CPI. That measure rose 0.2% from the prior month, boosted by housing and food, which accounted for over 75% of the advance. Goods prices rose as well after reliably falling over the past year.

The higher-than-expected inflation figures, along with last week’s blowout US jobs report, will likely amplify the debate whether the Federal Reserve will opt for a small interest-rate cut next month or pause after a large September reduction. Officials penciled in another half-point of cuts by year-end, and many have said they’re watching developments in the labor market.

“Inflation is dying, but not dead,” said Olu Sonola, head of US economic research at Fitch Ratings. “Coming on the heels of the surprisingly strong September employment data, this report encourages the Fed to maintain a cautious stance with the pace of the easing cycle. The likely path is still a quarter point rate cut in November, but a December cut should not be taken for granted.”
