Securitization of mortgages and other loans by US banks was a catalyst for the 2008 credit crisis. Subprime loan securities were innovative and compelling but the lack of credit risk modeling and regulation lead to a nationwide bank failure. The Dodd-Frank financial overhaul law addresses the lack of regulation in this area by imposing a 5% credit risk requirement on banks for securitized mortgages and loans. Additional regulation on down payment requirements and mortgage ratings are likely to follow.
