LONDON, Feb 24 (Reuters) - Gold recovered early losses on Wednesday as the dollar weakened further against the euro after Federal Reserve Chairman Ben Bernanke said economic conditions will warrant low U.S. interest rates for an extended period.
The dollar also fell after data showed sales of new U.S. homes fell sharply in January, with fresh doubts about the U.S. economy leading investors to cut exposure to risk.
Spot gold <XAU=> was $1,100.45 at 1533 GMT, against $1,102.95 late in New York on Tuesday. Earlier, the metal hit its weakest since Feb. 12 at $1,089.45 an ounce after a break of key resistance levels just below $1,100 an ounce prompted selling.
"There has been a recovery in the euro, so gold is holding the $1,100 level," said Deutsche Bank trader Michael Blumenroth. "For the moment we are trading a broad range between $1,075 and $1,125."
The dollar extended early losses against the euro on Wednesday after Bernanke's testimony to Congress, and after data showed a sharp drop in new home sales in January, lifting gold prices back above $1,100 an ounce. [
]Weakness in the U.S. unit boosts gold's appeal as an alternative asset and makes dollar-priced commodities cheaper for holders of other currencies.
Bernanke offered a relatively downbeat assessment of the U.S. economy in his first appearance before Congress following a testy confirmation vote in the Senate last month, despite recent signs of strong growth. [
]U.S. stocks rose after Bernanke reaffirmed his commitment to keeping interest rates low, while U.S. Treasuries erased modest losses. [
]Meanwhile the U.S. Commerce Department reported sales of single-family homes fell 11.2 percent to a 309,000 unit annual rate in January, the largest drop in a year and a record low. [

COMMODITIES SLIP
Among other commodities, oil was little changed and base metals weakened as below-consensus U.S. consumer confidence data released on Tuesday continued to blunt appetite for assets perceived as higher risk. [
] [ ]A drop in bullion prices spurred some buying in parts of Asia, but main consumer India was on the sidelines. A lack of activity in China after the Lunar New Year holidays also put pressure on premiums. [
]The China Daily reported on Wednesday, citing an unnamed official from the China Gold Association, that China was unlikely to buy 191.3 tonnes of gold being offered for sale by the International Monetary Fund. [
]Silver <XAG=> was at $15.90 versus $15.82 an ounce, platinum <XPT=> at $1,505 an ounce versus $1,510, and palladium <XPD=> at $424.50 against $428.50.
South Africa's power regulator on Wednesday granted state-owned utility Eskom a 24.8 percent tariff increase for the 2010-11 financial year, falling short of the power firm's request for a 35 percent hike. [
]South Africa is the world's biggest platinum producer and one of the leading miners of palladium and gold.
"(This) will make mining in South Africa a bit more expensive, but in the long run it will make it more reliable as well," said one European platinum group metals trader. (Reporting by Jan Harvey; Editing by Amanda Cooper)
