But excluding volatile food and energy costs, “core" prices, a gauge of underlying inflation, remained elevated in September, driven up by rising costs for medical care, clothing, auto insurance and airline fares. Core prices in September were up 3.3% from a year earlier and 0.3% from August. Economists closely watch core prices, which typically provide a better hint of future inflation.
Alan Detmeister, an economist at UBS Investment Bank, suggested that some items that contributed to higher core inflation last month, notably used cars, may rise again in the coming months, keeping prices a bit elevated. But other items that rose in price in September, like clothing and air fares, are more volatile and should cool soon.
"Things are still gradually coming down, but there is going to be volatility month to month," said Detmeister, a former Federal Reserve economist.
Taken as a whole, the September figures show that inflation is steadily easing back to the Fed’s 2% target, even if in an uneven pattern. That decline suggests that the Fed will likely keep cutting its benchmark interest rate this year, with two quarter-point reductions in November and December expected by most economists.
On a positive note, apartment rental prices grew more slowly last month, a sign that housing inflation is finally cooling, a long-awaited development that would provide relief to many consumers.
