TransUnion发布汽车贷款欺诈损失研究并宣传反欺诈解决方案

TransUnion (NYSE: TRU) today released new research revealing that despite a decline in incidents across many fraud types, fraud losses in auto lending have increased significantly in recent years. The findings point to a fraud environment impacting dealerships and auto lenders where fewer events drive greater financial losses. Today’s fraudsters have evolved to concentrate on higher-value opportunities throughout the lending lifecycle, especially as new and used vehicle prices reach heightened levels.

Auto lenders are facing substantially higher fraud-related losses across multiple fraud categories. Between Q3 2018 and Q3 2025, losses tied to first-party, third-party and synthetic fraud increased significantly. First-party fraud, which occurs when an individual deliberately provides false information or misrepresents themselves to obtain goods, services or credit, experienced the largest increase. It saw estimated losses rising from $88 million to $323 million—an increase of approximately 267% over the period.
Gaps in fraud detection, especially resolving identities, open the door to large charge-off losses by lenders and dealerships that most often are not found out until weeks or months later and are not recoverable.

Third-party Fraud $18 million $47 million
Synthetic Fraud $93 million $208 million

Third-party fraud, which involves the use of another person’s identity without their knowledge or consent, is a clear example of the divergent trends of incidences and losses. In auto lending, the incidence rate in Q3 2025 was less than half its Q3 2018 level, yet associated losses were 2.6 times higher. Similar trends were observed for other types of fraud. These gaps show how fraudsters are becoming more strategic and executing fewer schemes while targeting larger loan balances and generating greater losses.
Though less common, third-party fraud can produce substantial losses due to the high balances associated with fraudulent auto loans. Some of the largest losses occur among traditionally lower-risk, higher-credit tiers, where fraud incidence is lower, but loss severity is significantly higher.

A Growing Threat: Credit Washing and Hidden Credit Risk
Beyond traditional fraud activity, lenders are also confronting emerging forms of identity and credit manipulation that can mask underlying risk. Credit washing, in particular, is creating new challenges by artificially enhancing the creditworthiness of some borrowers.
Credit washing conceals critical risk signals and undermines the accuracy of credit-based decisioning. Consumers with suppressed negative tradelines can exhibit risk levels similar to much lower credit tiers despite appearing prime or above prime at origination. In some cases, they are several times more likely to experience early charge-off in the 12 months following origination than borrowers without suppressed credit events.

“Credit washing is one of the more concerning emerging trends because it fundamentally distorts how lenders assess risk,” said Naureen Ali, U.S. head of fraud at TransUnion. “When negative credit information is removed or suppressed, consumers can appear more creditworthy than they really are, leading to a higher likelihood of early default.”
In 2025, roughly 5% of U.S. consumers have had charged-off accounts suppressed for atypical reasons, with an estimated $10 billion in debt erased from credit reports, creating disproportionate risk and decisioning blind spots. These findings reinforce the need for lenders to look beyond traditional credit attributes and incorporate deeper identity intelligence into their processes.
Ali continued, “The goal of fraud solutions like TransUnion's suite of fraud solutions is to help lenders and dealers uncover and identify hidden risks. Whether it is credit washing or identity-based fraud, by combining identity verification and linkage analytics, synthetic ID detection, and anomalies on the credit file, TransUnion can help lenders uncover those hidden risks earlier and allow lenders to make more informed lending decisions.”
