]EURO RESUMES SLIDE
The euro fell against the dollar as investors pocketed part of the rally that had taken the single currency to its highest level in more than two months.
Traders said the euro was unable to remain above the key resistance level of $1.27 due to lingering worries about the euro-zone economy.
"Since the 1.1877 June low, the euro has rallied an impressive 6.1 percent," said Camilla Sutton, a currency strategist at Scotia Capital in Toronto. "However, near-term risks continue to loom and we will see another bout of euro weakness."
The single European currency <EUR=> was down 0.42 percent at $1.264 from a previous session close of $1.2693.
The single currency got a lift on Thursday after Jean-Claude Trichet, the European Central Bank president, said the euro zone's economy performed much better in the second quarter. However, he also said the region would grow "at a moderate and still uneven pace in an environment of high uncertainty."
The dollar was also up against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.09 percent. Against the Japanese yen, the greenback <JPY=> was 0.1 percent stronger at 88.46.
U.S. Treasury prices fell as higher global stocks reduced the safe-haven allure of government bonds but also because investors made room for $69 billion worth of coupon-bearing supply next week.
The U.S. Treasury Department will sell $35 billion in three-year debt on Monday, $21 billion in 10-year notes on Tuesday and $13 billion in 30-year bonds on Wednesday.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was down 5/32 in price, with the yield at 3.0556 percent.
Gold prices rose back above $1,210 an ounce. Some investors were cautious about the U.S. earnings season and others found the metal attractively priced. Spot gold <XAU=> jumped 1.32 percent to $1,211.20 an ounce. (Additional reporting by Jan Harvey in London and Edward Krudy, Vivianne Rodrigues and Richard Leong in New York; Editing by Kenneth Barry)
