Sticky Inflation Is Testing the Fed’s Resolve

Last week’s surprisingly bad inflation figures pose a dilemma for the Federal Reserve. In recent speeches and interviews, Fed officials suggested they were in no hurry to raise interest rates again and that a pause might be appropriate. But holding the rate now looks harder to justify.

Consumer prices rose in September by 0.6%, the fastest pace in five months, lifting year-over-year inflation to 3.7%, up from 3.4% in August. Excluding volatile food and energy prices, core CPI inflation rose to 2.6% from 2.4%. The Fed gives greater weight to the price index for personal consumption expenditures, a number that won’t be out until Oct. 29, but new figures for wholesale prices suggest that PCE inflation will also come in higher than expected.

The data show that elevated energy costs, due mainly to the conflict with Iran, are feeding through to transportation prices. Wholesalers are evidently restoring their profit margins, squeezed by tariffs as well as fuel prices, by passing along more of their increased costs. And inflation in services, running at 3.2% in the year to September, suggests the problem isn’t confined to the sectors most affected by tariffs or the war.

Granted, it’s unwise to read too much into a single month’s data, but these are indications that excess inflation — still well above the Fed’s 2% target — might persist without further monetary tightening. Underlining that concern, market-based measures of long-term expected inflation are inching higher.
