From Bloomberg:

The global financial system in 2008 experienced its worst crisis since the Great Depression of the 1930s. Major financial institutions went bust. Others were bought up on the cheap or survived only after major bailouts. Global stock markets fell by more than 50 percent from their 2007 peaks. Interest-rate spreads spiked. A severe liquidity and credit crunch appeared. Many emerging-market economies on the verge of a crisis had to ask for help from the International Monetary Fund.
