NEW YORK, April 21 (Reuters) - U.S. stocks rose on Tuesday, led by financial stocks, after the U.S. Treasury secretary said American banks are well capitalized, while the euro rose versus the dollar on improvemed German investor confidence in April.
Market sentiment turned in the morning, with U.S. government debt prices paring gains to turn negative and crude oil paring early losses to trade back above $46 a barrel as traders awaited more clues about demand.

]Crude oil, bonds and currency markets have been tracking moves in equities as traders look for signs of a recovery from the global slowdown sparked by the financial crisis. Banks are key to investor sentiment as they are crucial to a recovery.

U.S. equities rose after Geithner, who appeared confident unlike past testimony, said government plans to clear toxic assets from bank balance sheets were working, said Marc Pado, U.S. market strategist at Cantor Fitzgerald & Co.
"You can't argue with the fact that the banks seem to have stabilized," Pado said. "They're booking profits that may not be repeatable, but they're sufficient to handle the provisions they're putting forth for future losses."
