Despite rising Treasury yields, auto loan rates have remained stable or even fallen. This is because the previously wide spreads—the difference between Treasury yields and auto loan rates—have significantly narrowed, absorbing the impact of the rising base rates for consumers.

The removal of leverage lending guidelines will not cause a simple shift from private credit back to banks. Instead, it will accelerate the convergence of public and private credit markets. Banks will now compete across the entire financing continuum, further blurring the distinctions in terms and cost between the two.

Recent stress in credit card and auto loan markets is concentrated in loans originated in 2021-2023 when stimulus and looser standards prevailed. Lenders have since tightened, and newer loan portfolios are performing better, suggesting the problem is not spreading systemically.

Over 15 years, auto loans transformed from the best-performing loan product to the riskiest. This shift is driven by a "double whammy" of soaring vehicle prices—which outpaced even mortgage growth—and rising interest rates, compounded by overlooked costs like insurance and repairs.

A key risk identified in a Bloomberg survey is worsening underwriting standards. This is driven by new entrants ('tourists') to the private credit market who may be offering looser loan terms and conditions in an effort to quickly build their portfolios.

Rising delinquencies in subprime auto are not a sign of a uniformly weak consumer. The underperformance is largely confined to loans originated from 2022-2024, which were impacted by a unique combination of inflated used car prices and sharply higher interest rates, leading to strategic defaults.

Despite a rise in auto loan delinquencies, default rates have remained low. This is because high used vehicle values ensure that the collateral securing the loan retains significant worth. Lenders face lower potential losses on repossessions, making the asset class attractive despite shakier payment performance.

An alternative data point from Equifax reveals significant economic stress. The delinquency rate for subprime auto loans (borrowers with scores below 660) has reached 10%, a level higher than that observed during the 2008-2009 global financial crisis, signaling trouble for lower-income households.

In a highly concerning paradox, delinquency rates for subprime auto loans are now higher than they were during the 2008 financial crisis when unemployment was 10%. This signals extreme stress among lower-income consumers even in a strong labor market.
