Introduction
An Asset-Backed Security (ABS) is a financial instrument whose collateral is composed of a pool of financial obligations like mortgages, car loans, or credit card receivables. The concept falls under the broader umbrella of securitization and plays a significant role in structured finance.
Historical Context
Asset-backed securities emerged in the late 20th century as a way for lenders to offload the risk associated with various types of loans. The practice began in earnest with mortgage-backed securities but later expanded to encompass other forms of debt.
Types/Categories of Asset-Backed Securities
Mortgage-Backed Securities (MBS)
- Collateralized by mortgage loans.
- Further divided into Residential Mortgage-Backed Securities (RMBS) and Commercial Mortgage-Backed Securities (CMBS).
Auto Loan-Backed Securities
- Collateralized by automobile loans.
Credit Card Receivable-Backed Securities
- Collateralized by outstanding credit card debt.
Student Loan-Backed Securities
- Collateralized by student loans.
Key Events
- 1970s: Introduction of the first mortgage-backed securities by Ginnie Mae.
- 1985: Launch of the first auto loan-backed securities.
- 1990s: Expansion into credit card and student loan-backed securities.

Detailed Explanations
Mechanism of Asset-Backed Securities
- Origination: Financial obligations like loans are originated by lending institutions.
- Pooling: These financial obligations are pooled together to form the collateral.
- Securitization: The pool is securitized into bonds or notes that are sold to investors.
- Cash Flow Distribution: Cash flows from the underlying assets are distributed to investors in the form of interest and principal payments.
Mathematical Models
Mathematical models such as Monte Carlo simulations and risk-adjusted return calculations are often used to evaluate ABS. Here’s an example formula used in valuation:
where \(CF_t\) is the cash flow at time \(t\) and \(r\) is the discount rate.
