Key US Inflation Gauge and Spending Pick Up in Solid Economy

The Federal Reserve’s preferred measure of underlying US inflation posted its biggest monthly gain since April, bolstering the case for a slower pace of interest-rate cuts following last month’s outsize reduction.

The so-called core personal consumption expenditures price index, which strips out volatile food and energy items, increased 0.3% in September, and 2.7% from a year earlier, according to Bureau of Economic Analysis data out Thursday. Overall inflation was 2.1%, the lowest since early 2021 and just above the central bank’s 2% goal.

Inflation-adjusted consumer spending advanced 0.4%, an acceleration from the prior month supported by continued growth in wages and salaries. The saving rate fell to 4.6%, the lowest since 2023.

Thursday’s figures cap a month of upside surprises in key economic reports that will likely augur a cautious approach to rate cuts in the months ahead. The Fed is widely expected to authorize a second reduction at the conclusion of its Nov. 6-7 policy meeting following an initial cut in September.

“The new information is the trajectory of consumption heading into this quarter. The increase in real consumer spending in September puts it on a favorable course, removing some downside risk to our forecast,” Ryan Sweet, chief US economist at Oxford Economics, said in a note. “Growth in real disposable income is a little light, but with inflation expected to decelerate a little, household purchasing power will get a lift.”
