TOKYO, Jan 20 (Reuters) - Platinum hit a 17-month high on Wednesday, buoyed by the recent launch of exchange-traded funds backed by the metal, while gold inched down due to pressure from a firmer dollar.
Spot platinum <XPT=> rose as high as $1,654 per ounce, a level last seen in August 2008. It was at $1,646.50 at 0306 GMT.
A U.S. subsidiary of London's ETF Securities launched platinum and palladium exchange-traded funds earlier this month, and both metals have been climbing since then.
The metal, which like palladium is also valued for its industrial use in autocatalysts, is expected by some market participants to head higher.
Bank of America Merrill Lynch on Tuesday raised its 2010 platinum forecast to $1,750 an ounce from $1,440 an ounce, on the launch of the new funds and an improving auto sector.
"Platinum still has room to go up to $1,680 and technically, we will see some sort of resistance there," said a dealer in Hong Kong.
Sister metal palladium <XPD=> paused but continued to trade near 18-month highs marked this week.
It was at $461.75, down from $464.50 in New York.
Kazuhiko Saito, chief analyst at Fujitomi Co Ltd, said hopes that Chinese gross domestic product data would show strong growth was helping to support the market.
Strong economic growth would help spur use of platinum and palladium due to their industrial applications.
"It's difficult to sell in a market under these conditions," Saito said.
Gold prices jumped earlier this month on fund buying driven by stronger-than-expected Chinese import data.
Spot gold <XAU=> was at $1,134.40 per ounce, down 0.3 percent from the New York notional close of $1,137.95.
U.S. gold futures for February delivery <GCG0> were at $1,135.10, down 0.4 percent from the settlement in New York.
The world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD>, said its holdings stood at 1,111.922 tonnes as of Jan. 19, down 0.08 percent from the previous business day. [
