NEW YORK, Sept 22 (Reuters) - U.S. stocks, bonds and the dollar fell on Monday as investors questioned the impact the U.S. government's $700 billion bailout for troubled banks would have on the country's economy and already strained budget.
The dollar weakened broadly as skeptical investors tried to sort out the details of the rescue plan, while government debt prices in the euro zone and the United States extended losses due to concerns about the how much this would cost Washington. Congress would need to increase the U.S. government's debt limit to $11.3 trillion from $10.6 trillion.
Gold was higher in early New York trade, climbing during the European session as the dollar weakened and concern about the success of the U.S. financial bailout plan spread.
U.S. crude oil futures rose as a weaker dollar and trimmed output from Saudi Arabia helped extend oil's rally late last week, even after a more than 6 percent jump on Friday. U.S. light sweet crude oil <CLc1> rose $3.52 to $108.07 a barrel.
In the European stock market, banks shares gained and helped the overall stock market higher after Japan's biggest bank Mitsubishi UFJ Financial said it planned to buy 10 percent to 20 percent of the common stock of Morgan Stanley. The Wall Street firm is abandoning its investment bank model and becoming a bank holding company.
But European shares turned lower after Wall Street opened,
"The U.S. plan has calmed nerves, but I don't think people believe it will take out all the problems yet," said Standard Bank analyst Walter de Wet. "Details are still sketchy. We need to see when and how the plan the will be implemented."
