At the end of 2007, Bear Stearns was the fifth largest investment bank in the United States but its market capitalization had deteriorated through the second half of the year. On Friday, March 14, 2008, Bear Stearns lost 47% of its equity market value as rumors emerged that clients were withdrawing capital from the bank. Over the following weekend, it emerged that Bear Stearns might prove insolvent, and on March 15, 2008, the Federal Reserve engineered a deal to prevent a wider systemic crisis from the collapse of Bear Stearns.
