The US Subprime Mortgage Crisis in 2007 has had a severe impact on the global financial system. The collapses of Bear Stearns and Lehman Brothers, the acquisition of Merrill Lynch by the Bank of America and the conversion of Morgan Stanley and Goldman Sachs into bank-holding companies have all resulted from this subprime crisis that shocked the world and directly triggered the greatest global financial crisis since the Great Depression.
The underlying factors leading to the crisis were in fact the new inventions in the US housing market – the subprime mortgage lending and securitization technology that significantly magnified the impact of the default risk of these loans on the whole financial system.
This report, hence, aims to provide an understanding of how the subprime mortgage lending and securitization played a part in bringing about the Subprime Mortgage Crisis in 2007.

Besides, external influences such as actions by the government and the central bank as well as the possible impact of the 2009 Financial Regulatory Reforms would also be addressed.
