Definition§
An Asset-Backed Security (ABS) is a financial instrument that is collateralized by a pool of underlying assets. These assets might include mortgage loans, car loans, credit card receivables, and cash flows from leases. The value and income payments of an ABS are directly derived from these underlying assets. The process of securitization allows for the risk associated with these assets to be distributed among investors, creating an ABS that can be sold in the financial markets.
The market for ABS grew significantly during the early 1990s, but the failure of these securities to make the promised payments was a major factor in the financial crisis of 2007-2008.
Historical Context§
The concept of securitization emerged in the late 20th century, revolutionizing the way financial markets operate:
- Early Beginnings: The first mortgage-backed security (MBS) was issued in 1968 by Ginnie Mae.
- Growth in the 1990s: The ABS market expanded rapidly in the 1990s, diversifying into various types of asset classes.
- 2007 Financial Crisis: The failure of ABS, particularly mortgage-backed securities, to meet expected payments triggered a financial meltdown. This highlighted the inherent risks of securitization and poor underwriting standards.
