This document summarizes the 2008 financial crisis and its impacts. It discusses how the bursting of the housing bubble in the United States, marked by rising default rates on subprime mortgages, triggered the crisis. As major financial institutions like Lehman Brothers collapsed due to their exposure to these risky mortgages, stock markets plunged substantially. The Dow Jones Industrial Average fell over 50% from its peak in October 2007 to its trough in March 2009. Countries around the world, including India, felt significant impacts through falling stock prices, currency depreciation, and reduced foreign investment.
