NEW YORK/LONDON, June 19 (Reuters) - Gold climbed back through $900 an ounce on Wednesday to a 10-day high as an initial pick-up in oil prices, which sparked buying of gold as an inflation hedge, sent the precious metal through key technical levels.
Gold <XAU=> reached a peak of $907.90, its highest since June 9, before easing with oil to trade at $902.95/904.35 by New York's last quote at 2:15 p.m., against $890.75/891.95 late in New York on Wednesday.
"(Gold) has been threatening this for the last few days," said Simon Weeks, director of precious metals trading at Scotia Capital.
"Gold is starting to find its feet, given the global (inflationary) environment we are in, and given what we have seen coming out in terms of U.S. data releases," he added. "General sentiment is good."
The metal shrugged off a firmer U.S. dollar on Thursday, as other factors took over. A brief move higher in oil prices based on a report of attacks in top supplier Nigeria was enough to start the precious metal's rally on Wednesday.
However, U.S. crude futures <CLc1> settled down $4.75 at $131.93 a barrel on news that China will raise retail gasoline and diesel prices, hampering global energy demand. [
]Frank McGhee, head precious metals trader of Integrated Brokerage Services in Chicago, said that oil's early strength was enough to trigger heavy buy-stops in gold futures, which propelled prices sharply higher.
A COMEX floor trader also cited pent-up demand after gold's recent price weakness for Thursday's rally.
The U.S. gold contract for August delivery <GCQ8> on the COMEX division of New York Mercantile Exchange settled up $10.70, or 1.2 percent, at $904.20 an ounce.
Rising fears over inflation on both sides of the Atlantic and uncertainty over the outlook for currency and equity markets are boosting gold, which is a popular safe haven for funds.
The metal has historically benefited from economic turmoil, and the threat of recession hanging over the United States in the past year. Concerns over the health of equity markets have also firmly underpinned the metal.
Gold reached an all-time high of $1,030.80 in March as the weak dollar, rising oil prices and concerns over the economic outlook spurred buying.
The technical picture is looking good for gold, analysts said, with another close above $888 seen as giving the precious metal a solid floor for an upward move.
POWER WOES PLAGUE SOUTH AFRICA
Platinum prices ended lower as traders took profits after the white metal climbed 1.5 percent on Wednesday.
The metal rallied after a South African official warned the country could face a "very severe energy crisis" if state power utility Eskom failed to raise sufficient funds to bankroll development.
Johannesberg-based Standard Bank analyst Walter de Wet said that while higher power tariffs are likely to be absorbed by producers and should not have much impact on price, any sign that mines will receive less power could boost the market.
"While cost-wise, electricity might have a small effect, production-wise it is essential," he said. "In this regard, mines have committed to cutting electricity consumption, irrespective of Eskom's power-rationing measures."
Spot platinum <XPT=> was down at $2,036.50/2,056.50 an ounce from its late New York quote of $2,080.50/2,100.50 on Wednesday. It rallied to $2,103.50 an ounce in the last session, its highest since May 28.
Spot palladium <XPD=> was last at $468.50/476.50 an ounce from $466.00/474.00 last in the U.S. market on Wednesday. Silver <XAG=> was at $17.36/17.42 an ounce from its previous finish of $17.33/17.43. (Editing by Christian Wiessner)
