Mortgage Backed Securities

Mortgage Backed Securities (MBS) are products that use pools of mortgages as collateral for the issuance of securities in the secondary market and are issued by both private institutions and Government Sponsored Entities (GSEs). The major GSE players in the secondary mortgage market in issuing and guaranteeing MBSs are the Government National Mortgage Association (Ginnie Mae), the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac).

The Mortgage Backed Securities (MBS) market is huge–reaching $300 billion in average daily trading by 2006, and estimated total outstanding debt of some $3.12 trillion dollars as of 2007. The essence of MBSs is to take illiquid loans and convert them into tradable securities to provide liquidity to the housing market.

Due to the success of the MBS markets, as of the first quarter 2007, U.S. national homeownership rate was 68.4 percent. The purpose of this collection of articles is to provide an overview of the MBS market, and to highlight some of the recent troubles in the mortgage markets that will likely lead to a new wave of litigation.
