What is a Collateralized Debt Obligation (CDO)?

A Collateralized Debt Obligation is a financial instrument that pools various types of debt and repackages them into different tranches that can be sold to investors. The value of a CDO is derived from the underlying assets, which serve as collateral in case of default.

Understanding Collateralized Debt Obligations (CDOs)

CDOs are divided into different tranches based on the level of credit risk. These tranches include senior, mezzanine, and equity levels. The senior tranche has the lowest risk and lower returns, while the equity tranche has the highest risk and higher returns. This structure allows investors to choose a level of risk that matches their investment strategy.

The Creation of Collateralized Debt Obligations (CDOs)

CDOs were created as a tool for financial institutions to shift risk and free up capital. By pooling various types of debt and repackaging them into different tranches, banks can sell these tranches to investors, thereby moving the risk of default from the bank to the investors.
