Sticky Inflation Clouds Fed’s Path to Rate Cuts

Fresh signs of stubborn inflation are complicating the Federal Reserve’s effort to persuade households and markets that price pressures are on a durable path downward.

Data released Thursday showed that the personal consumption expenditures price index, the Fed’s preferred inflation measure, rose 4.1 percent in May from a year earlier. Excluding volatile food and energy prices, core P.C.E. climbed 3.4 percent, the fastest pace since October 2023. Consumer spending, meanwhile, increased 0.7 percent in May, underscoring that demand remains firm even as borrowing costs stay elevated.

The figures arrive just over a week after the central bank left its benchmark interest rate unchanged at 3.5 percent to 3.75 percent, extending a pause that officials have used to assess whether inflation is cooling enough to justify eventual rate cuts. Instead, the latest report suggested that progress remains uneven.

Fed officials offer contrasting emphasis

That tension was evident in remarks from two senior Fed officials on Thursday.

Austan Goolsbee, the president of the Federal Reserve Bank of Chicago, said in a CNBC interview that inflation remains “well too high” and is moving in the wrong direction, particularly on the core measure. He declined to speculate on the path of interest rates, but his comments reflected concern that the recent data could make it harder for the Fed to ease policy soon.

John C. Williams, president of the Federal Reserve Bank of New York, struck a more reassuring note. He said he still expected inflation pressures to diminish later this year and argued that current policy was “well positioned” to bring inflation lower over time.

The difference was less a direct disagreement over the Fed’s ultimate goal than over how much confidence officials can place in the cooling trend. After months of trying to balance patience with optimism, policymakers are now confronting data that risk reviving fears that inflation could settle well above the central bank’s 2 percent target.

A harder case for rate cuts

The hotter core reading is especially uncomfortable for the Fed because it tends to be watched as a better guide to underlying inflation. A rise to 3.4 percent, the highest level in more than two years, weakens the argument that inflation is steadily converging toward target.

It also reinforces a message that financial markets have heard repeatedly in recent months: rates may need to stay higher for longer.

When officials met on June 17, they opted to keep policy unchanged, and their updated projections already suggested a slower return to price stability than they had once hoped. The median forecast showed overall P.C.E. inflation at 3.6 percent in 2026 and core inflation at 3.3 percent, both still well above the Fed’s goal.

That backdrop makes Thursday’s data more consequential. If inflation is proving sticky even with rates in restrictive territory, officials may feel little urgency to cut borrowing costs, particularly while consumer spending remains resilient.

What is keeping prices elevated

Fed officials have pointed to several forces behind the renewed pressure. Mr. Williams has cited tariffs, higher energy and commodity costs linked to the conflict in the Middle East, and strong demand in some technology categories tied to the artificial intelligence boom. The Fed’s June policy statement also noted that inflation remained elevated in part because of energy-related supply shocks.

Some of those drivers could fade if oil and commodity markets stabilize and if temporary trade-related price increases do not broaden. But a stronger consumer backdrop could keep services inflation stubborn, raising the risk that one month’s disappointing data turns into a more persistent pattern.

That is now the central question confronting policymakers, investors and consumers alike: whether May marks a temporary flare-up or evidence that inflation is re-accelerating.

For the Fed, the answer matters not only for the timing of any rate cuts, but for its credibility after a long campaign to restore price stability. Officials have argued that current policy is restrictive enough to finish the job. The latest numbers suggest that job may take longer than they had hoped.
