LONDON, Oct 15 (Reuters) - Gold slid below $1,370 an ounce in volatile trade on Friday, having earlier jumped to within a few dollars of the previous day's record high, as currency markets see-sawed after a speech by Federal Reserve Chairman Ben Bernanke.
The U.S. unit dipped versus the euro and fell to parity with the Australian dollar after Bernanke said there was a case for further monetary policy action, given low U.S. inflation and high unemployment. [
]It quickly pared those losses, however, to turn higher against the single currency.
Spot gold <XAU=> was bid at $1,371.40 an ounce at 1325 GMT against $1,376.75 late in New York on Thursday, having earlier slipped as low as $1,365.50. U.S. gold futures for December delivery <GCZ0> fell $5.20 to $1,372.40.
"(We are) building up to a profit-taking Friday -- probably healthy, given the recent run-up," said Saxo Bank senior manager Ole Hansen.
"The question is for how much longer the market is prepared to run just on the quantitative easing story. I think the market at these levels wants to see the facts before committing addtional capital to the upside."
Gold has climbed more than 25 percent so far this year as the prospect of further quantitative easing in the United States undermined the dollar and prompted investors to buy the precious metal as a safe store of value.
Even given their current correction, gold prices remain on track for a fifth week of gains, and have rallied to a series of record highs in recent weeks, peaking at $1,387.10 an ounce on Thursday, as the dollar continued its decline.
But the U.S. unit bounced back on Friday, with the euro erasing early gains made versus the dollar as analysts said much of the impact from additional Fed easing has been priced in.
QUANTITATIVE EASING
Quantitative easing is seen undermining the dollar in the longer term and may also indicate that the U.S. authorities are likely to keep interest rates near historic lows, analysts said.
Gold benefits from low interest rates, which cut the opportunity cost of holding non-interest bearing assets. Goldman Sachs, which recently lifted its 12-month price view on gold to $1,650 an ounce, said the metal is still a good buy in the current environment.
"We expect gold prices to continue to rise from current levels as real interest rates should remain low on a continuation of accommodative U.S. monetary policy," the bank said in a note.
In the options markets, investors are betting heavily on the gold price continuing to rise. The bulk of open interest for December gold options centres on call options at $1,400 an ounce, which give holders the right, though not the obligation, to buy gold at that price. [
]Open interest amounts to well over 17,000 contracts, equivalent to 1.7 million ounces of gold, compared with the bulk of open interest on December puts of 250 contracts at a strike price of $1,360 an ounce.
Investment in gold exchange-traded funds picked up, with holdings of the world's largest, New York's SPDR Gold Trust <GLD>, edging higher on Thursday after falling by almost 20 tonnes in early October. [
]In India, the world's biggest gold consumer, wholesale gold buying rose on Friday afternoon after the rupee strengthened to its highest level in 25 months, making the dollar-quoted yellow metal cheaper for local buyers, dealers said. [
]Among other precious metals, silver <XAG=> was at $24.47 an ounce against $24.61, platinum <XPT=> at $1,687.50 an ounce versus $1,704.15 and palladium <XPD=> at $592 versus $597.45. (Editing by James Jukwey)
