LONDON, Dec 8 (Reuters) - Gold was set for its largest one-day fall in a month on Wednesday after initial weakness stemming from a stronger dollar was exacerbated by a flurry of profit-taking a day after the metal reached a record peak.
Gold hit an all-time high at $1,430.95 an ounce on Tuesday as risk aversion flared in the euro zone, but has now fallen by about 3.8 percent after the rally ran out of steam.
Spot gold <XAU=> was bid at $1,375.02 an ounce at 1600 GMT, against $1,400.86 late in New York on Monday, having earlier fallen by as much as 2.1 percent to a one-week low of $1,371.45. U.S. gold futures for February delivery <GCG1> fell $36.0 an ounce to $1,373.10.
"It really is just good old fashioned profit-taking," said Credit Agricole analyst Robin Bhar. "This year every time gold makes a new high, it subsequently, collapses," he added.
"It is noticeable that we had quite an influx of momentum traders as well, as the price was moving higher and they're notorious for being short-term players."
Setting gold on the backfoot early in the day was a rally in the dollar, after a proposed extension in U.S. tax cuts prompted a spike in bond yields on Tuesday, which in turn raised the cost of holding gold to non-U.S. investors [
]While gold has shaken off its traditional inverse relationship with the U.S. currency in the past, when risk aversion has worsened, this has not been the case this week, when the negative correlation has strengthened.
"Clearly there is a more risk-negative tone across the markets today, but I don't think it's been enough to push people into gold's safe-haven qualities," said RBS analyst Daniel Major.
"If you do get higher yields, the opportunity cost of holding a zero-yielding asset like gold is a bit of a concern but it's more of a currency play in the near term," he said.
Benchmark 10-year Treasury yields <US10YT=RR> fell by more than a point on the day, forcing yields to six-month highs above 3.25 percent. [
]The rise in Treasury yields is seen as being supportive to the dollar in the near term, while the tax deal itself could lift growth next year and lessen the case for bigger monetary stimulus by the Federal Reserve.
This set the euro on track for a third straight day of losses. While this has weighed on gold, the metal has proved it can break its inverse link with the dollar if worries over euro zone debt lifts its safe-haven appeal while pressuring the euro.
On the investment front, holdings of the world's largest gold-backed exchange-traded fund, the SPDR Gold Trust <GLD>, eased to 1,297.726 tonnes by Dec 7 from 1,298.030 tonnes a day before. [
]The world's largest silver ETF, iShares Silver Trust <SLV>, said its holdings hit another record at 10,941.34 tonnes by Wednesday. [
]Silver <XAG=> was bid at $28.09 an ounce against $28.66, still well off the 30-year high at $30.68 it reached on the previous day, causing the gold/silver ratio in turn to pull back from its recent near-four year low. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For a graphic showing the evolution of the gold-silver ratio, click on: http://r.reuters.com/wyk88q ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^>
Platinum <XPT=> was at $1,671.74 an ounce against $1,688.50, while palladium <XPD=> was at $718.22 versus $729.97.
ETFS Physical Palladium Shares, the New York-based palladium exchange-traded product operated by ETF Securities, said its holdings hit a record 1.084 million ounces on Tuesday, having broken through a million ounces for the first time a day before.
