US Used Car Prices: The Pandemic Spike and Its Unwind

For most of modern history, used cars did what used cars are supposed to do: lose value over time. Then 2021 happened. A pandemic-driven shortage of new vehicles sent used-car prices soaring more than 40% in a single year — a once-in-a-generation distortion that became a poster child for pandemic inflation. This guide charts used-car prices since 1995, breaks down the extraordinary 2021 spike, and shows how much of it has since unwound.

How much did used car prices rise?

The chart tracks the Consumer Price Index for used cars and trucks. For decades it drifted within a fairly narrow band — then it shot almost straight up in 2021, reaching a peak far above anything in the prior record. At the height of the spike, the typical used vehicle cost dramatically more than it had just a year earlier, an unheard-of move for a category that normally depreciates.

The 2021 spike: why used cars went crazy

The cause was a collision of supply and demand. A global semiconductor shortage choked production of new cars, so buyers who couldn't get a new vehicle flooded into the used market. At the same time, rental companies and dealers were short on inventory, and stimulus-boosted households had money to spend. With far more buyers than cars, prices for used vehicles — normally abundant — spiked to record highs, a textbook supply-shock.

Have used car prices come back down?

Partly. As new-car production recovered and the chip shortage eased, the year-over-year change turned negative — used prices actually fell for a stretch, the unwind shown in the second chart. But they haven't returned to their pre-pandemic level; like much of the post-2020 economy, prices settled at a permanently higher plateau rather than fully reversing. The wild swings, at least, have calmed down.

Why used cars matter to the inflation story

Used vehicles became famous during the inflation surge because they were such a large, visible driver of it — a single category swinging the overall Consumer Price Index. Economists watched used-car prices closely as an early sign of both the inflation spike and its eventual cooling. Their rise and fall is a clean case study in how a targeted supply shock can ripple through the headline inflation rate that everyone feels.
