Car owners could discover they owe far more than car is worth as sky-high prices fade

Drivers who took on auto loans at high interest rates and paid sky-high prices for cars could face some headaches down the road as car values pull back in an economic slowdown.

The car you're looking to trade in — particularly if you bought a used car — could be worth far less than you'd imagine. And lenders are growing more concerned about people falling behind in their car payments, especially if that car drops significantly in value.

The outlook is most worrisome for borrowers with subprime credit scores who bought used cars as prices and interest rates hit a peak.

"They often go and purchase a vehicle because they really need it," Satyan Merchant, senior vice president of the auto business at TransUnion, told the Free Press.

How negative equity is a growing worry

The new and used auto market is moving farther away from the days of shockingly low supplies on car lots that contributed to skyrocketing prices. In some cases, used car prices are going down more than they have in the recent past.

Negative equity — or owing more on your car than it's worth — is building, particularly in used cars bought by subprime borrowers, according to a new study called "Finding Opportunity in Uncertain Times" by TransUnion and J.D. Power.

Not surprisingly, the researchers noted, consumers with more equity in their car or truck appear more likely to protect that equity by making payments.

The real problems pop up when someone needs to buy a new car — and doesn't have $3,000 or $5,000 sitting on the sidelines to cover what they still owe on the old car that they'd like to trade in. You might have to take on an even bigger car loan and an even bigger monthly payment to get another set of wheels.

Or try to sell that car on your own to get a better price. Or delay buying, if you can.

The average payment on a used car bought in the first quarter of 2023 hit $523 a month. That's up nearly one-third from payments for used cars bought in the first quarter of 2020, according to the new TransUnion-J.D. Power report. File photo: A car lot in Pittsburgh on Sept. 29, 2022.

What is a loan to value ratio?

The auto industry pays close attention to loan to values ratios — the difference between the loan amount and the market value of the car. The higher the number, the more vulnerable the consumer.

In the first quarter of 2023, the average loan to value ratio on a used car bought then was 125% — up from 112% three years earlier. In this case, you'd owe 25% more than the used car is worth.

Rising loan to values are important to consider, according to Merchant, because they can be used to predict higher delinquencies among used auto finance customers, particularly with subprime customers.

As vehicle values have declined in recent quarters, TransUnion noted, used car loan-to-value ratios at origination have trended upward.
