What are CDOs?
A Collateralized Debt Obligation (CDO) is a type of structured asset-backed security that pools together various cash flow-generating assets and sells claims on this pool to investors. These assets can include mortgages, bonds, auto loans, and other forms of debt.
Key Concepts
CDOs work by repackaging debt into different risk categories called tranches. Each tranche has a different priority for receiving payments from the underlying assets and a corresponding level of risk and potential return.
- Senior Tranches: Lowest risk, lowest yield, paid first.
- Mezzanine Tranches: Medium risk, medium yield, paid after senior.
- Equity Tranches: Highest risk, highest potential yield, paid last.
Deep Dive into Structure
The process involves a special purpose vehicle (SPV) that buys the debt assets. The SPV then issues securities (the CDO tranches) to investors. The performance of these tranches is directly tied to the performance of the underlying debt pool.
Applications and Use Cases
CDOs were widely used by financial institutions to manage risk, diversify portfolios, and generate income. They allowed originators of debt to move assets off their balance sheets, freeing up capital for new lending.
Challenges and Misconceptions
A major challenge with CDOs, particularly evident during the 2008 financial crisis, was the opacity of the underlying assets. Mispricing risk and complex structures led to significant losses when defaults rose.
