Prices climbed rapidly in 2021 and 2022, straining American household budgets and chipping away at President Biden’s approval rating. But inflation cooled in late 2023, a spurt of progress that happened more quickly than economists had expected and that stoked hopes of a gentle economic landing.

Now, the question is whether the good news can persist into 2024.

As forecasters try to guess what will happen next, many are looking closely at where the recent slowdown has come from. The details suggest that a combination of weaker goods prices — things like apparel and used cars — and moderating costs for services including travel has helped to drive the cooldown, even as rent increases take time to fade.

Taken together, the trends suggest that more disinflation could be in store, but they also hint that a few lingering risks loom. Below is a rundown of the big changes to watch.

What’s happening in America right now is what economists call “disinflation”: When you compare prices today with prices a year ago, the pace of increase has slowed notably. At their peak in the summer of 2022, consumer prices were increasing at a 9.1 percent yearly pace. As of November, it was just 3.1 percent.

Still, disinflation does not mean that prices are falling outright. Price levels have generally not reversed the big run-up that happened just after the pandemic. That means things like rent, car repairs and groceries remain more expensive on paper than they were in 2019. (Wages have also been climbing, and have picked up more quickly than prices in recent months.) In short, prices are still climbing, just not as quickly.

The Federal Reserve, which is responsible for trying to restore price stability, wants to return price increases to a slow and steady pace that is consistent with a sustainable economy over time. Like other central banks around the world, the Fed defines that as a 2 percent annual inflation rate.
