Securitization is often blamed for aggravating -- if not causing -- the subprime mortgage crisis that keeps roiling U.S. real estate and credit markets. By repackaging pools of mortgages into securities that could be resold to investors the argument goes securitization permitted unscrupulous underwriters to offer housing loans to poor borrowers and transfer the risk to Wall Street. How then will the present credit crisis affect the future of securitization? According to professors from Wharton’s finance and real estate departments securitization will not disappear -- but it is in for radical changes.
