NEW YORK/LONDON, May 28 (Reuters) - Gold rose more than 1 percent on Thursday, fueled by a weakened dollar, inflation concerns and renewed buying by investment funds.
Spot gold <XAU=> rose to a two-month high of $964.95 an ounce -- the loftiest price since March 20 -- as the dollar lost more ground against the euro, while silver hit a fresh nine-month peak above $15 an ounce.
Spot gold traded at $960.80 an ounce at 3:04 p.m. EDT (1904 GMT), up 1.3 percent from its late Wednesday quote in New York of $948.10 an ounce.
U.S. gold futures for August delivery <GCQ9> settled up $8 at $963.20 an ounce on the COMEX division of the New York Mercantile Exchange.
"New fund buying came in over $955, and a crude rally, euro's gains and technical buying also helped gold," said George Gero, vice president of RBC Capital Markets Global Futures. "Silver was helped by option activity from funds getting long positions in December contracts."
Silver <XAG=> hit a high of $15.25 an ounce, its firmest level since August 2008. It was last at $15.15 an ounce, up 2.9 percent from its previous finish at $14.72.
"Platinum and palladium are following gold. Silver is putting in a great performance above $15 and the euro is clearly up," said Gerry Schubert, head of precious metals at INTL Commodities.
"The weak long positions have been taken out of the gold market," he added. "What you see is good quality buying, and for the first time this month we are seeing physical buying out of Turkey and Middle East."
LOWER DOLLAR SUPPORTS GOLD
Reports in the United States showed better-than-expected readings on durable goods orders and weekly jobless claims, boosting risk appetite and hurting the dollar. [
]Gold has recently re-established its close negative correlation with the U.S. currency after the relationship weakened earlier this year, as risk aversion took the driver's seat in both the bullion and currency markets. [
]Meanwhile, a heightened military alert for the Korean peninsula by the United States and South Korea over a nuclear test by the North boosted the safe-haven appeal in gold, traders said. [
]The prospect of rising inflation in the longer term is also likely to support gold, a key hedge against rising prices.
Investor demand for the metal remains relatively soft after the heavy buying seen in early 2009. Holdings of the main gold exchange-traded fund, the SPDR Gold Trust <GLD>, were unchanged, albeit near record levels, for a third straight session.
Holdings of a much smaller ETF operated by Swiss bank Julius Baer <BAER.VX> are expected to rise to a record 1.599 million ounces by Friday, however. [
]Among other precious metals, platinum <XPT=> was at $1,141.00 an ounce, up 0.8 percent from its late Wednesday quote of $1,131.50 in New York, while palladium <XPD=> was at $225 an ounce, up 1.4 percent from its previous finish of $222.
Platinum group metals turned higher on a broad-based commodities rally. Initially, however, they were pressured by fears over the demand outlook, especially from the ailing auto sector, which typically consumes half of the world's annual output of the white metal as a component in exhaust system catalytic converters.
General Motors <GM.N> made an improved equity exchange offer to bondholders with $27 billion in debt intended to pave the way for a quick bankruptcy process. [
]"GM seems set for bankruptcy and this is keeping investors cautious on platinum and palladium, hence the currently low platinum/gold ratio of 1.19," said UBS analyst John Reade in a note. (Reporting by Frank Tang and Jan Harvey; editing by Jim Marshall)
