LONDON, Sept 14 (Reuters) - Gold was set for its largest one-day rise this month on Tuesday, in line with a pickup in other safe-haven assets as the U.S. dollar fell broadly, while silver nudged at two-year highs.
Palladium, used predominantly in autocatalysts, struck four-month highs as a combination of fund buying and growing prospects for industrial demand lifted prices.
Spot gold <XAU=> was at $1,254.05 an ounce by 0855 GMT, up from $1,245.25 the day before. U.S. gold futures for December delivery <GCZ0> were last up $8.60 an ounce at $1,255.0.
"All four precious metals are really keeping a very close eye on the U.S. dollar right now and if the dollar doesn't 'shape up,' as such, this safe-haven buying will continue in the precious metals," said Afshin Nabavi, head of trading at MKS Finance.
A raft of economic data from both the euro zone and the United States later in the day should offer further proof of the health of both regions and will be particularly important in whetting investor appetite for gold.
"People will be looking at that for some direction, but overall, I would say given the economic situation in the U.S. as well as ongoing geopolitical tensions we are pretty much on our way towards breaking $1,265 and thereafter, up to $1,300," Nabavi said.
SENTIMENT
The euro slid against the dollar <EUR=> after an indicator of German economic sentiment fell unexpectedly in September, according to the ZEW institute, which releases the survey.
ZEW said the decline may not indicate a temporary slowdown, but rather a flattening in economic activity. [
]The dollar extended losses on Tuesday to hit 15-year lows against the Japanese yen and plumbed nine-month lows against the Swiss franc, another key safe-haven asset, while euro zone government bond yields also declined. [
] [ ]Gold is on track for a near-14 percent rise this year, fuelled primarily by investors seeking an alternative to volatile currencies, equities and some sovereign bonds as economic data has cast doubt on the global growth outlook.
Although the price remains within 0.8 percent of late June's record-highs, the market is now in the full throes of the buying season in some of the world's biggest consumers.
"Physical demand is picking up, mostly in India and China, as people are trying to finish their Christmas orders," said Dick Poon, manager at Heraeus in Hong Kong. "It's already September."
Singapore dealers said Thai buyers were active, while Indonesian consumers were still on holiday. <GOLD/ASIA1>
Holdings of gold in the world's largest exchange-traded fund, the SPDR Gold Trust <GLD.P>, dropped to 1,292.619 tonnes by Sept. 13 from 1,293.531 tonnes by Sept. 10. [
]Adding further support to gold was a decline on the equities markets, where major European indexes tilted into negative territory. [
]Across the rest of the precious metals complex, silver traded at its highest in 2-1/2 years, helped by robust Chinese industrial output and firm base metals, although the safe-haven effect boosting gold was also a driving force. [
]"Silver has been extremely volatile, especially around these numbers," said MKS's Nabavi. "In essence, it's really a cheap way of getting into the precious metals world without paying $1,250-odd an ounce."
Spot silver <XAG=> was last at $20.32 an ounce, up from $20.02 the day before and on course for its third consecutive day of gains.
In the platinum group metals, palladium <XPD=> hit its highest in four months, trading above $540 an ounce.
"We're getting better noises coming out of the euro zone about projected growth and industry and obviously, palladium is quite tightly linked to industry," one European trader said.
Palladium, which is predominantly used in the production of auto catalysts, is on track for a 33 percent increase this year and is one of the top performers of the entire commodities complex.
Palladium was last at $542.00, up from $524.95 on Monday, while sister metal platinum <XPT=> was last quoted at $1,570.50 an ounce, up from $1,543.65 the day before. (Additional reporting by Lewa Pardomuan in Singapore; editing by Sue Thomas)
