Peering Under the Hood of Auto and Credit Card ABS: Insights into US Consumer Resilience

In previous Notes, we have explored asset-backed securities (ABS) backed by data centers and critical AI infrastructure. In this week’s edition, we shift our focus to another critical segment of the ABS market: those tied to consumer loans, such as credit cards and auto loans. Despite recent weakness, the long-term health of the US consumer remains robust, and this resilience is mirrored in the performance of ABS, which have benefited from significant structural changes in underwriting standards and ABS structures.

ABS derive their value from a pool of underlying cash flow-generating assets, such as loans, leases, or credit card balances. The process of creating ABS is known as securitization, where a financial institution bundles assets into a portfolio, separates the aggregated assets into sections called "tranches," and then sells them to investors. This structure allows the issuer to convert illiquid assets into marketable securities, providing a steady stream of income to investors while enabling the issuer to raise funds.

One common method to structure an ABS is credit tranching, where the ABS are divided into different layers or "tranches," each with varying levels of risk and return. The most senior tranches, often rated AAA, have the highest credit protection and are the first to receive payments, making them the safest portion in the structure. Subordinate tranches, which bear losses first, offer higher returns to compensate for their increased risk. Other credit enhancement techniques include overcollateralization, where the value of the underlying assets exceeds the value of the issued securities, and excess spread, which uses the difference between the interest earned on the assets and the interest paid to investors as a buffer against potential losses. These structures help ensure that ABS remain attractive to a wide range of investors by balancing risk and return.

ABS Structure Example

Credit card and auto loan ABS offer a unique lens into consumer spending habits and financial health. By analyzing the performance and delinquency trends of these strategies, investors can gain insights into the real economy. For instance, an increase in credit card ABS issuance might indicate higher consumer spending and confidence, while a rise in auto loan ABS could reflect strong demand for vehicle financing. Softening economic conditions could result in higher delinquency and weaker credit fundamentals, which could appear in assets underlying these ABS.
