Convulsive day on Wall Street

Global markets were reeling Monday after a convulsive day on Wall Street that saw a leading U.S. investment bank file for bankruptcy and other institutes scramble to merge as the credit crunch claimed one of its biggest victims yet.

Stock prices plunged in Asia and Europe in the wake of investment bank Lehman brothers announcing its collapse and Bank of America's $50 billion buyout of ailing brokerage Merrill Lynch.

This crisis is clearly deeper than anybody had imagined only a short time ago," Peter Stein, an associate editor at the Wall Street Journal in Asia, told CNN.

The Dow Jones Industrial Average fell 330 points or 2.9 percent to around 11091 in early trading. In Europe, FTSE index in London declined 3.37 percent while the Paris CAC 40 was down 4.47 percent.

Major Asian indexes were closed but India's Sensex fell 5.4 percent, Taiwan's benchmark dropped 4.1, Australia's key index dropped 2 percent and Singapore fell 2.9.

The turmoil followed a roller-coaster weekend for a Wall Street already concussed by woes at other major financial firms and mortgage-financing titans Fannie Mae and Freddie Mac.

At one point the U.S. Federal Reserve was forced to step in, announcing plans to loosen lending restrictions to the banking industry in an effort to calm markets, while a consortium of 10 leading domestic and foreign banks agreed a $70 billion fund to lend to troubled financial firms.

In an effort to calm market jitters, the European Central Bank on Monday said it has pumped $42.6 billion into money markets. The Bank of England in London also took steps, offering nearly $9 billion in a three-day auction.
