NEW YORK, July 15 (Reuters) - U.S. stocks headed for a lower open on Tuesday as concerns about the credit crisis' impact on the financial sector curbed investors' appetite for riskier assets and sent stocks lower around the globe.
Stocks fell about 2 percent in Japan and Europe. The euro surged to an all-time high against the dollar, while oil prices rebounded. Cautious investors gravitated toward the relative safety of government debt.
Bank shares were poised to lead losses, with shares of U.S. Bancorp <USB.N> down 6.6 percent at $21.80 before the bell after it said mounting credit losses led to a larger-than-expected drop in quarterly profit. For details, see [
]S&P 500 futures <SPc1> dropped 10.90 points and were below fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average futures <DJc1> tumbled 100 points, and Nasdaq 100 <NDc1> futures slid 11 points.
Investors will scrutinize testimony from Federal Reserve Chairman Ben Bernanke before the Senate Banking Committee at 10 a.m. (1400 GMT).
"People are wondering what is he going to say with regards to interest rates, with the economy being so brittle," said Anthony Conroy, head trader at BNY ConvergEx, an affiliate of the Bank of New York.
"You continue to see downgrades with financials, even at these levels. I think that's creating more nervousness, and nervousness creates volatility, and that's what we're seeing."
Shares of General Motors <GM.N>, a Dow component, climbed 2.8 percent to $9.65 after the automaker announced a restructuring plan and said it is suspending its dividend as part of an effort to bolster its finances. [

Despite the U.S. government's efforts to calm markets with a rescue plan for mortgage finance companies Fannie Mae <FNM.N> and Freddie Mac <FRE.N>, investors feared the credit turmoil may be escalating, raising risks for the U.S. economy and the global financial system.
In addition to Bernanke, President George W. Bush, Treasury Secretary Henry Paulson and Securities and Exchange Commission Chairman Christopher Cox are all due to speak later on Tuesday. (Additional reporting by Deborah Jian Lee; Editing by Kenneth Barry)
