The latest price figures arrive as Fed officials, led by Chair Jerome Powell, are considering whether their benchmark interest rate is high enough to quell inflation or if they need to impose another rate hike in coming months. Powell said last week that Fed officials were “not confident” that rates were high enough to tame inflation. The Fed has raised its benchmark interest rate 11 times in the past year and a half, to about 5.4%, the highest level in 22 years.

The costs of many services, notably rents, travel and health care, are still rising faster than before the pandemic. Services prices typically change more slowly than the cost of goods, because they largely reflect labor costs, which aren’t directly affected by interest rates.

The central bank’s rate hikes have increased the costs of mortgages, auto loans, credit cards and many forms of business borrowing, part of a concerted drive to slow growth and cool inflation pressures. The Fed is trying to achieve a “soft landing” — raising borrowing costs just enough to curb inflation without tipping the economy into a deep recession.

The rate increases have had some impact: Year-over-year inflation has dropped from a peak of 9.1% in June 2022, the highest level in four decades, to 3.7% in September. That figure is forecast to have fallen further in October to 3.3%.

Last week, Powell warned that if inflation didn’t cool fast enough, the Fed “will not hesitate” to raise rates further. Still, the central bank’s policymakers have left their key short-term rate unchanged since July, and most economists say they think the Fed is done hiking.

Prices first accelerated in 2021 as consumers stepped up spending amid a fading pandemic. Much greater demand ran headlong into snarled supply chains, which led retailers and other companies to quickly jack up prices. Inflation has since eased as supply chains have improved and higher borrowing rates have weakened some industries, notably housing.

But in his remarks last week, Powell said that further reductions in inflation might require a cooldown in spending in addition to further improvements in supply networks — a distinction that potentially points to further hikes.

Economists are keeping a close eye on several inflation metrics, including the cost of rent and housing, health insurance and services such as dining out, entertainment and travel. Starting with Tuesday’s price report, the government is altering how it calculates health insurance costs, and the changes are expected to result in higher overall inflation rates in the coming months.

Many economists say a key reason why most Americans hold a gloomy view of the economy despite very low unemployment and steady hiring is that the costs of things they buy regularly — milk, meat, bread and other groceries — remain so much higher than they were three years ago. Many of these items are still growing more expensive, though more gradually.
