Securitisation and Derivatives: What went wrong?

Securitisation is not a new development and has been very useful tool in the financial sector for a long time so what went wrong this time?

In the case of the current financial crisis this resulted in pooling together of various Jumbo, Alt-A, and Subprime loans. This is where the real mess happened. Somehow, mixing up a combination of these risky loans resulted in investments with AAA ratings. With low interest rates, these investments provided an exceptional level of return for the perceived level of risk. As a result of this these products were in high demand and could be traded without requiring a credit assessment.


Many investors hedged against the risk of default by purchasing a credit-default swap. Derivatives, described by Warren Buffet as "financial weapons of mass destruction" in early 2003 were had also exploded during this period. According to the International Swaps and Derivatives Association, in 2008 the estimated value of CDS’s in the market was $62 trillion.


So the Banks had removed these securities off their balance sheets and had insured themselves in case of them defaulting. However in 2007, when house prices began to fall and delinquencies increased there was also a fall in demand for subprime backed securities. The credit rating agencies suddenly realized that their investment grade ratings were incorrect and had provided a false sense of security to investors. This resulted in the credit rating agencies downgrading these securities which in turn caused investors to start selling them. Many securities fell below investment grade so demand for these products fell rapidly.

This led for the demand of insurers to meet their commitments to their CDS’s and guarantees. Many did not even know who was currently holding them and whether the holders can actually pay in the event of a negative credit event. It soon became quite clear that many insurers were unable to meet their commitments. These CDS’s were not regulated, not traded on an exchange, subject to re sale and subject to counterparty risk. For example when Lehman Brothers went bankrupt, any CDS protection it offered was nullified.
In my opinion, this was the primary cause of the subprime mortgage crisis in America coupled with the credit rating agencies inability to fairly rate such products that I will discuss next week
