* Euro rises vs dollar on profit-taking
* U.S. stocks mixed in volatile trade
* Gold hits record high on flight-to-safety

NEW YORK, June 8 (Reuters) - The euro rose against the U.S. dollar on Tuesday, but U.S. stocks ended mixed in choppy trading as investors remained jittery about Europe's debt troubles.
U.S. Federal Reserve Chairman Ben Bernanke's reassuring comments on the state of the U.S. economy late Monday helped support U.S. stocks, but a report by Fitch Ratings that the UK faced a "formidable" fiscal challenge pushed European stocks to near two-week closing lows.
Risk-averse investors streamed into gold, sending prices for the precious metal to a record dollar high amid fears that euro zone credit contagion could stunt global economic growth.
Bernanke said the U.S. economy seemed to have enough momentum to avoid a "double-dip" recession, while European leaders were committed to ensuring the survival of the euro and had enough money to meet obligations of heavily indebted member nations. For details, see [
]Still, traders remained anxious about debt levels in several euro zone countries, as Portugal, Italy and Spain prepared to sell new bonds this week. It will be the first sale by Spain since a credit ratings downgrade.
"Investors are sort of cautiously paring back their international exposure and, even within the S&P 500, trying to position in a domestic theme," said Jack Ablin, chief investment officer of Harris Private Bank in Chicago.

The euro rose above $1.20 against the dollar a day after hitting its lowest level since March 2006, and pared losses against the Swiss franc as traders cited possible intervention by the Swiss National Bank. [

"The euro decline isn't over," said Marc Chandler, senior strategist at Brown Brothers Harriman in New York. "There are supply concerns this week, and what we're seeing now is a brief respite. A rise above $1.20 would be a good chance to sell."
The pound fell after Fitch urged Britain to cut its deficit, the latest in a series of concerns expressed by rating agencies about the state of government finances in Europe, encompassing Greece, Spain, Hungary, and Ireland. [

Meanwhile, safe-haven U.S. Treasury debt prices fell giving up some recent gains, as investors reduced safe-haven holdings to prepare for this week's $70 billion in government bond supply.
The first of this week's three auctions -- $36 billion of three-year notes -- received solid demand on lingering worries over contagion from Europe's sovereign debt crisis.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was down 10/32, with the yield at 3.1803 percent. The 2-year U.S. Treasury note <US2YT=RR> was down 2/32, with the yield at 0.742 percent. The 30-year U.S. Treasury bond <US30YT=RR> was down 15/32, with the yield at 4.1077 percent.
Spot gold prices rose above $1,250 an ounce, a record high, benefiting from fears the European sovereign debt crisis may spread, weighing on a global recovery.
"It is mainly the fear of another slide into recession which is seeing demand for gold as a safe haven," said Commerzbank analyst Daniel Briesemann. (Additional reporting by Rodrigo Campos, Richard Leong and Steven C. Johnson in New York)
