TOKYO, Jan 13 (Reuters) - Gold was little changed on Wednesday with investors seeking new trading factors after a broad sell-off in commodities the previous day when China's surprise monetary tightening sapped investor appetite for riskier assets.
China started tightening monetary conditions on Tuesday as the world's third-largest economy roars ahead, surprising investors with an increase in banks' required reserves and rattling global financial markets. [
]Spot gold <XAU=> steadied after falling more than 2 percent on Tuesday after the news, marking the biggest one-day percentage loss since Dec. 17. It has slid 2.8 percent from a five-week high of $1,161.50 marked on Monday.
Technical selling had dragged prices lower after spot bullion fell below its 50-day moving average at $1,130, analysts said.
While analysts said further aggressive selling was unlikely, gold was still vulnerable to a technical correction as new money inflows from fund managers in the past weeks had helped prop up gold prices.
"The news on China's central bank triggered a wave of selling. But the market still looks a bit overbought after active buying by index funds especially at the start of the year," said Tetsu Emori, a fund manager at Tokyo-based asset manager Astmax Co.
Gold was trading at $1,128.70 an ounce as of 0615 GMT on Wednesday, little changed from New York's notional close of $1,127.95.
U.S. gold futures for February delivery <GCG0> were at $1,129.20 an ounce, also little changed from $1,129.40 on the COMEX division of the New York Mercantile Exchange. Futures settled Tuesday down $22 or 1.9 percent.
Astmax's Emori said historical data shows that reversals of rallies between late December to early January often result in a 6-10 percent correction before bottoming out.
Volatility in commodity prices could stay high in the coming days as passively managed index funds are set to rebalance their holdings in line with the new weighting portfolio for 2010 by such commodity indexes like S&P GSCI <.SPGSCI> and Dow Jones UBS <.DJUBS>. [
]Hiroyuki Kikukawa, general manager of market research at Nihon Unicom, also said volatility will remain high for commodities, including gold, for the next week or so, as players keep a close eye on news out of China.
"Commodities have been rising since the start of the year, so it's time for some correction," he said. He added gold was likely to test the downside near $1,110 on China-related news.
In the currency market, the euro stayed on the defensive against the dollar <EUR=>, retreating from a four-week high above $1.45 on Monday. [
]The holdings of the world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD>, extended recent declines. But physical buying by newly listed U.S. platinum and palladium ETFs rose in the first two trading sessions.
SPDR Gold Trust said its holdings fell 3.657 tonnes or 0.3 percent to 1,115.884 tonnes on Tuesday, the lowest level since mid-November. [
]As of Monday, ETFS Physical Platinum Shares <PPLT> had bought 80,000 ounces of platinum, while the ETFS Physical Palladium Shares <PALL> held 90,000 ounces of palladium, a ETF Securities spokeswoman said. [
]Spot platinum <XPT=> was at $1,572 an ounce against its notional New York close of $1,568.50. Spot palladium <XPD=> was at $423 against $421.50.
On Tuesday, platinum reached $1,624, its highest since August 2008, while palladium hit an 18-month high of $439.
