NEW YORK, Sept 17 (Reuters) - Gold hit a record high on Friday for the third time this week as poor U.S. consumer data and market talk of more quantitative easing put the alternative asset on track for its largest weekly gain since May.
Silver <XAG=> rose to just below $21 an ounce, approaching levels not seen since 1980 as gold's rally triggered further investor speculation that the white metal would continue a winning streak that began in August.
Gold surged to an all-time peak of $1,282.75 an ounce in the European session on expectations that the U.S. Federal Reserve, hoping to stave off double-dip recession, could announce more quantitative easing -- usually a boon for gold.
After some profit-taking, the metal turned higher again after data showed consumer sentiment worsened in early September to its weakest in more than a year. Another report indicated little underlying U.S. inflationary pressure. [
]"Gold continues to reflect the overall level of concern. The weak consumer confidence data was certainly supportive to the rally in gold," said Frank McGhee, head of precious metals trading at Integrated Brokerage Services in Chicago.
Spot gold <XAU=> fetched $1,275.55 an ounce at 11:53 a.m. EDT (1553 GMT), compared with $1,272.20 late in New York on Thursday. It has gained more than $100, nearly 9 percent, since the start of August.
U.S. December futures <GCZ0> climbed $3.40 to $1,277.20 an ounce.
Foreign-exchange volatility also boosted gold's appeal as an alternative currency, after Japan intervened on Wednesday to weaken the yen for the first time in six years and the United States sharpened its tone on China's currency policy. [
]"It's partly a currency move. There's certainly investor nervousness about monetary policy around the world since the yen intervention," precious metals strategist Matthew Turner of Mitsubishi Corp said.
"A lot of people are sensing a race to the bottom by central banks to print more of their currency, to reflate their economies and gold is getting support from that."
The dollar rallied against the euro and the yen as the U.S. consumer data eased risk appetite against the backdrop of possible further intervention by the Bank of Japan. [
]Dollar sentiment overall has been damaged by speculation that the Fed could announce more quantitative easing when it meets on Tuesday.
Quantitative easing is a process by which central banks attempt to pump money into economies by printing cash and buying bonds. Excess liquidity can often lead to price pressures as too much money chases too few goods and services.
SEASONAL DEMAND, GOLD-BUYING EVENTS
September and October are typically seasonally strong periods for jewelry demand, with a number of major gold-buying festivals near the year-end in top consumer India, while Western manufacturers stock up ahead of Christmas.
Also lending background support this week was the long-expected announcement of AngloGold Ashanti's <ANGJ.J> capital raising, a key function of which was to buy back its outstanding gold hedges. [
]Eclipsing gold's rally, silver has gained more than 5 percent this week, outperforming the yellow metal's 2.5 percent increase. Spot silver <XAG=> was up 0.2 percent at $20.77 an ounce from $20.72 in New York on Thursday.
"The last few months, silver has been benefiting as a monetary metal like gold, when things are looking bad, and as an industrial metal when things are looking good. So investors are very keen," Mitsubishi's Turner added.
However, according to technical analysis, silver is overbought and could be due a correction.
"Silver is renowned for overshooting and undershooting, so this rally can get more exponential but we are already up 18 percent since late August," Credit Suisse analyst Tom Kendall said.
"In my opinion, that kind of rate of increase can't be sustained. I would not be recommending anyone to get long or longer silver at $21."
Spot platinum <XPT=> hit $1,630 an ounce, its highest since May 19. It rose to $1,621 from $1,603.65 on Thursday and palladium <XPD=> edged up to $546.50 an ounce from $544.65. Prices at 12:09 p.m. EDT (1609 GMT)
