Subprime Crisis

Sub-prime crisis

Causes of the sub prime crisis

Credit rating agencies are now under scrutiny for giving investment-grade, "money safe" ratings to securitization transactions (CDOs and MBSs) based on subprime mortgage loans. These high ratings encouraged a flow of global investor funds into these securities, funding the housing bubble in the U.S.[1] An estimated $3.2 trillion in loans were made to homeowners with bad credit and undocumented incomes (e.g., subprime or Alt-A mortgages) between 2002 and 2007. These mortgages could be bundled into MBS and CDO securities that received high ratings and therefore could be sold to global investors. Higher ratings were believed justified by various credit enhancements including over-collateralization (i.e., pledging collateral in excess of debt issued), credit default insurance, and equity investors willing to bear the first losses.

The crisis can be attributed to a number of factors pervasive in both housing and credit markets, factors which emerged over a number of years. Causes proposed include the inability of homeowners to make their mortgage payments, due primarily to adjustable-rate mortgages resetting, borrowers overextending, predatory lending, speculation and overbuilding during the boom period, risky mortgage products, high personal and corporate debt levels, financial products that distributed and perhaps concealed the risk of mortgage default, monetary policy, international trade imbalances, and government regulation (or the lack thereof). Three important catalysts of the subprime crisis were the influx of moneys from the private sector, the banks entering into the mortgage bond market and the predatory lending practices of the mortgage lenders, specifically the adjustable-rate mortgage, 2-28 loan, that Mortgage Lenders sold directly or indirectly via Mortgage Brokers. On Wall Street and in the financial industry, moral hazard lay at the core of many of the causes.
