WASHINGTON — A measure of inflation may have fallen to a five-year low in January as rental costs have cooled, a sign that some prices are moderating while Americans continue to grapple with a big rise in overall prices in the past five years.

Inflation is forecast to have fallen to a 2.4% annual rate in January from 2.7% in December in the latest government report on consumer prices to be issued Friday. That would be the lowest rate in nine months. Core prices, which exclude the volatile food and gas categories, are expected to decline to 2.5% from 2.6%, the lowest in nearly five years, according to data provider FactSet.

On a monthly basis, inflation may show signs of remaining elevated: Overall and core prices are expected to rise 0.3% in January from December, a pace that if maintained for several months would start to push annual inflation higher.

Friday’s report may point to cooling inflation, but it comes after the cost of food, gas, and apartment rents have soared since the pandemic, with consumer prices about 25% higher than they were five years ago. The increase in such a broad range of costs has become a high-profile political issue under the rubric of “affordability.”

If inflation gets closer to the Federal Reserve’s target of 2%, it could allow the central bank to cut its key short-term interest rate further this year, as Trump has repeatedly demanded. High borrowing costs for things like mortgages and auto loans have also contributed to a perception that many big-ticket items remain out of reach for many Americans.

In January, economists expect that gas prices will have declined, while the cost of groceries could rise again after they jumped in December. Overall prices could increase by more than expected, economists say, because costs often rise more in January than other months as companies reset their prices at the beginning of the year.

Inflation surged to 9.1% in 2022 as consumer spending soared at the same time supply chains snarled in the wake of the pandemic. It began to fall in 2023 but leveled off around 3% in mid-2024 and has since barely improved.

Inflation cooled a bit this fall, though some of that reflected the disruptions of the six-week government shutdown in October. The shutdown disrupted the government’s data collection and led them to estimate price changes in November for housing that most economists say artificially lowered inflation that month.

At the same time, measures of wage growth have declined in the past year or so as hiring has cratered. With companies reluctant to add jobs, workers don’t have as much leverage to demand raises. Smaller pay increases can reduce inflationary pressures as companies often raise prices to offset higher wages.

More modest wage growth is a big reason that many economists expect inflation to continue easing this year.

“We’re not expecting inflation to start up again by any stretch,” said Luke Tilley, chief economist for Wilmington Trust.

Many businesses are still eating some tariff costs and economists expect they may raise prices more in the next few months to offset those extra expenses. Still, most forecast that inflation will decline further by the second half of the year and drop closer to the Fed’s 2% target by the end of 2026.
