CDO Squared (Ofer Abarbanel online library)

CDO-Squared is a collateralized debt obligations backed primarily by the tranches issued by other CDOs.[1] These instruments became popular before the financial crisis of 2007–08. There were 36 CDO-Squared deals made in 2005, 48 in 2006 and 41 in 2007. Merrill Lynch was a big producer, creating and selling 11 of them.[2]     

The collapse of the market for collateralized debt obligations and CDO-Squared contributed to the 2008 subprime mortgage crisis.[3] Goldman Sachs appears to be the last bank to hold CDOs-Squared, holding $50 million in June 2018.[4]
