Student loan dynamics have entered a pivotal new phase, as repayments fully resume and delinquency rates begin to climb. For auto lenders, the implications reach far beyond education debt. Recent insights from TransUnion highlight trends that are reshaping consumer credit behavior and exposing new layers of risk in auto portfolios.
The Scale of the Problem
The numbers are striking. As of May 2025, there were 41.0 million Americans holding student loan debt, with 18.7 million expected to make payments (excluding those in deferment, forbearance, or $0-payment status).¹ Among these borrowers, 29.8% were already 90+ days past due on their loans by May 2025. This represents about one in three borrowers, or 5.6 million individuals.¹ This is nearly triple the pre-pandemic adjusted delinquency rate of 11.5% and significantly exceeds the previous historical high of 15.4%. ¹
The picture becomes more troubling for the auto finance industry when considering payment behavior. As of May 2025, only 46.3% of student loan borrowers in active repayment were current.¹ Another 23.8% are late but have not yet reached or been officially reported delinquent. This means that over 50% of required borrowers are not making regular payments and that the true delinquency rate is likely to continue growing in the coming months.¹
Credit Score Devastation
The impact on credit scores is severe, particularly for high-quality borrowers who are central to auto lending profitability. Recent student loan defaults have led to steep average VantageScore® drops: super prime borrowers experienced an average decline of 174 points, prime plus borrowers fell by 119points, and prime borrowers dropped by 97 points.¹ Even near prime or subprime borrowers were affected, with average declines of 61 and 41 points, respectively.¹
What is especially troubling is the speed at which borrowers are exiting the prime credit tiers. Before default, 22% of student loan defaulters were in prime or higher categories. ¹ After default, very few remained (down to 2%), with the average score for this group dropping from 596 to 535.¹
The Auto Lending Connection
This is not simply a student loan crisis. TransUnion’s data show higher debt burdens and rising monthly payment obligations, especially for non-prime tiers. ¹ The share of consumers making payments above the minimum has dropped across all risk bands except super prime, signaling increasing financial strain in the broader market.¹
In auto lending, origination volumes did rebound with a 5.9% year-over-year increase in Q1 2025. However, volumes remain 5.5% below 2019 levels.¹ Auto loan account delinquency rates rose to 1.31% in Q2 2025, up from 0.63% in 2021, which is a clear sign of stress in the system.¹ The Federal Reserve has also warned that elevated student loan delinquencies can spill over into missed payments on other types of debt.²
Understanding the Cascading Effects
For auto lenders, the resumption of student loan payments after years of forbearance is reshaping how consumers prioritize their debts. In many cases, education loans now take precedence over auto loans due to the threat of wage garnishment and limited discharge options.²
This shift has led to delinquency patterns that traditional credit models struggle to forecast. Serious student loan delinquencies only began to reappear on credit reports in December 2024 and January 2025, after the return of payment obligations in October 2023 and the resumption of collections in May 2025.¹
Portfolio Implications
Auto finance portfolios are exhibiting several emerging areas of concern:
- Risk Migration: Borrowers previously categorized as prime are increasingly migrating into subprime tiers due to student loan defaults, despite maintaining positive auto payment histories.
- Payment Prioritization: A growing number of consumers are now allocating payments based on perceived urgency and penalty severity. In many cases, student loans are prioritized over auto loans.
- Model Performance: Rapid and widespread credit score declines are impacting millions and are reducing the predictive accuracy of legacy risk models. Traditional metrics may underestimate real-world risk, as 4.0 million borrowers required to make student loan payments became 90+ days delinquent within just a few months.¹
Strategic Considerations for Auto Lenders
To navigate this evolving environment, auto lenders should consider implementing more refined risk assessment approaches:
- Enhanced Due Diligence: Credit evaluations should go beyond summary-level credit bureau data. Analyzing how applicants manage education debt can offer better insight into future payment behavior.
- Segmented Strategies: Not all education borrowers should be treated as equivalent. Those with positive payment histories and declining balances may represent favorable credit profiles, despite carrying student loan debt.
- Portfolio Monitoring: Lenders should prepare for current customers to experience sudden credit score drops as student loan activity is reflected in credit reporting.
- Competitive Positioning: As credit conditions continue to tighten, lenders capable of accurately distinguishing between high- and low- risk borrowers may identify profitable, overlooked segments. This is especially relevant as non-captive auto finance companies face pronounced deterioration. ²
Looking Ahead
The student loan situation will likely get worse before it stabilizes. High rates of missed payments among borrowers required to make payments suggest that delinquency rates may continue to rise as reporting and collections catch up. ¹
For auto lenders, the challenge is significant, but there are also strategic opportunities. Avoiding all borrowers with student loans may reduce originations and result in missed opportunities to serve creditworthy applicants. In contrast, lenders that invest in analytics to separate higher-risk profiles from strong performers among student loan borrowers will be better positioned in a shifting market.
Conclusion
The student loan crisis is fundamentally reshaping the consumer credit landscape. Auto lenders that adapt their risk strategies using current, granular data, differentiate between types of education debt risk, and update their models to reflect new payment patterns will be better positioned to weather challenges and capitalize on emerging opportunities.
The disruption is both profound and enduring. The winners will be those who respond with speed, enhanced insight, and precision.
