LONDON, June 19 (Reuters) - Gold climbed to its higehst level in more than a week on Thursday as the weakening dollar added impetus to investors buying the precious metal to protect their assets against inflation.
Gold <XAU=> hit $895.05 an ounce, its highest since June 9, and was at $888.10/889.10 an ounce at 1020 GMT from $890.75/891.95 late in New York on Wednesday, when it jumped nearly $7 on a falling dollar and higher oil prices.
"The dollar is a supportive factor for gold ... Inflation concerns are still prominent, there will be some safe-haven buying," said Suki Cooper, analyst at Barclays Capital.
A lower U.S. currency makes metals priced in dollars cheaper for holders of other currencies, while gold is seen as a store of value during times of inflation, which is threatening to turn into a spiral.
The dollar <EUR=> fell against the euro as the market scaled back its expectations of aggressive rate rises from the U.S. Federal Reserve, given poor growth prospects and the crisis in the banking sector. [
]"Gold prices have been able to rally recently in large part because the U.S. Federal Reserve and European Central Bank softened their anti-inflation rhetoric," HSBC said in a note.
"Thus reducing the prospect of imminent monetary policy tightening and allowing financial markets to re-evaluate the chances of a U.S. rate rise."
PLATINUM UNDERPINNED
Gold hit a record of $1,030.80 on March 17 before a broad sell-off in commodities dragged down prices.
Oil steadied on Thursday, supported by a further production outage in Nigeria and as a top U.S. investment bank raised its oil price forecast. U.S. crude <CLc1> was down 37 cents to $136.31 a barrel. <O/R>
Platinum was off intraday highs but underpinned by supply worries after South Africa's power regulator approved an additional 13.3 percent tariff rise for state-owned power firm Eskom [
] on Wednesday. [ ]"Platinum we think has the strongest fundamentals within the precious metals complex, especially now as we've entered peak demand period for power in South Africa," Barclays Capital analyst Cooper said.
"Power problems in South Africa haven't been resolved and that will keep the market on tenterhooks."
Spot platinum <XPT=> was down at $2,068/2,088 an ounce from $2,080.50/2,100.50 on Wednesday. It rallied to $2,103.50 an ounce on Wednesday, its highest since May 28.
A power shortage in South Africa, the world's top producer of the metal used in autocatalytic converters, sparked worries about a supply deficit and propelled prices to an all time high of $2,290 in early March.
Spot palladium <XPD=> rose to $464.00/472.00 an ounce from $466.00/474.00 on Wednesday. Silver <XAG=> gained to $17.27/17.32 an ounce from $17.05/17.13.
