* Key Triggers
- Sub-prime mortgage
The meltdown originated in the sub-prime mortgage crisis in USA in 2007. With easy availability of credit at low interest rates, real estate prices in US had been rising rapidly since the late 1990s and investment in housing had assured financial return.

In 1975, the Securities Exchange Commission (SEC) established a net capital rule that required the investment banks who traded securities for customers as well as their own account, to limit their leverage to 12 times. However, in 2004 the Securities and Exchange Commission (SEC) allowed the five largest investment banks – Merrill Lynch, Bear Stearns, Lehman Brothers, Goldman Sachs and Morgan Stanley – to more than
