One of the largest investment banks in the country filed for bankruptcy protection, sending stocks plummeting Monday.
The announcement from Lehman Brothers, the fourth-largest investment bank in the US, came after the company lost billions of dollars from the recent mortgage crisis that crippled much of the market in previous months, according to the BBC.
Lehman, which had $639 billion in assets and $613 billion of debt, crumpled due nearly $60 billion in "soured" real estate investments, according to Forbes. The collapse is the largest bankruptcy in U.S. history.
US Treasury Secretary Henry Paulson cited "past excesses" as a source for the recent turmoil on Wall Street, but encouraged confidence "in the soundness and the resilience of our financial system.�
“As I’ve long said, the housing correction is at the root of the challenges facing our markets and our financial institutions," Paulson said. "I believe that we’ve taken very important steps with respect to Fannie Mae and Freddie Mac, and they’re amongst the most important actions we can take to work through this turmoil.�
Following the announcement by Lehman, Merrill Lynch also announced the wealth-management company would be purchased by Bank of America in a $50 billion deal. Merrill Lynch closed flat on the day, while Bank of America dropped by 21 percent, according to The New York Times.
Investors are not certain about Bank of America's decision to purchase Merrill Lynch, Marc Pado, a U.S. market strategist for Cantor Fitzgerald & Co., told Yahoo News. "There's some concern they might have bit off more than they could chew," said Pado.
The takeover means that three of the five top U.S. investment banks have collapsed following the mortgage crisis, less than six months after the crisis began, the BBC reported. There are also growing fears that American International Group (AIG), a major insurer, will collapse as well, as the company recently sought $40 billion in loans from the government.
