The Federal Reserve Bank of New York’s latest Household Debt and Credit Report finds new auto loan originations declined to $139 billion in the first quarter, a “modest” year-over-year decline. But originations for car buyers and lessees with sub-620 credit scores grew 13% to $27.9 billion, accounting for 21.8% of total outstanding auto balances.

Perhaps more concerning are 90-day delinquencies, which grew 9.2% year-over-year to account for 4.69% of all auto debt, the highest rate since 2011.

Originations for fair (620–659) credit borrowers accounted for $17 billion worth of originations for 13.3% of all balances. The biggest share belongs to prime (760-plus) customers, who borrowed $45.9 billion to claim 35.9% of the market.

Total U.S. household debt, which includes auto, home, and student loans, home equity lines of credit and credit-card balances, grew 0.9% to $13.67 trillion, meaning auto loans accounted for 9.4% of all debt in the first quarter. Mortgage balances grew by $120 billion and student loans grew by $29 billion year-over-year, but credit-card balances and home equity lines of credit fell by $22 billion and $6 billion, respectively.
