LONDON, Sept 10 (Reuters) - Gold edged back above $990 an ounce in Europe on Thursday as the dollar index weakened after U.S. weekly jobs data, fuelling interest in the precious metal as an alternative asset.
The metal remained under pressure, however, as investors cashed in gains after the metal's rise to 18-month highs earlier in the week, with the re-emergence of scrap selling also proving a drag on prices, traders said.
Spot gold <XAU=> was bid at $990.80 an ounce at 1254 GMT against $991.15 late in New York on Wednesday, having touched a low of $982.10 in earlier trade.
"In my view, the only reason gold is holding up here is the U.S. dollar," said Afshin Nabavi, head of trading at MKS Finance in Geneva. "Apart from the speculative (buying), we have not seen much buying interest."
He said selling of gold scrap had picked up as prices rose.
The metal rallied above $1,000 an ounce for only the third time in history on Tuesday after breaking a number of key technical resistance levels. News Barrick Gold was cutting its hedgebook of forward gold sales fuelled gains. [
]Gold is now mainly relying on dollar weakness for support. The dollar index <.DXY> declined on Thursday after data showed the number of workers filing new claims for jobless benefits fell last week. The euro hit a year-high against the U.S. unit. [
]A weak U.S. currency boosts interest in gold as an alternative asset, and also makes the dollar-priced precious metal cheaper for non-U.S. investors.
"The traditional inverse relationship between gold and the U.S. dollar appears to have been re-established during the current gold rally," said HSBC analyst James Steel in a note.
"The potential for U.S. dollar weakness is among the most compelling factors supporting the rally."
OIL CLIMBS
Crude oil prices climbed towards $72 a barrel on Thursday, further supporting gold, which is often bought as a hedge against oil-led inflation. [
]Oil is benefiting from a rise in stock markets, dollar weakness, and soothing words from the OPEC producer group. On the wider markets, world stocks and European equities rallied to 11-month highs, building on recent gains. [
]Traders say they are waiting to see whether the gains that took gold above $1,000 an ounce for only the third time in history on Tuesday can be sustained. If the metal seems vulnerable at higher levels, selling is likely to gain momentum.
Heraeus' head of sales Wolfgang Wrzesniok-Rossbach said gold had struggled to establish itself at higher levels.
"We have had bad news on physical demand from India and Turkey, we are seeing a lot of scrap coming in, for example from Hong Kong ... (and) industrial demand is low, so from a fundamental point of view there is no reason for gold to trade above $1,000," he added.
U.S. gold futures for December delivery <GCZ9> on the COMEX division of the New York Mercantile Exchange fell $5.10 to $991.90 an ounce.
Among other precious metals, silver <XAG=> fell to $16.37 from $16.27, platinum <XPT=> was at $1,277 against $1,276, while palladium <XPD=> was flat at $290.50.
ETF Securities said holdings of its London palladium-backed exchange-traded fund <PHPD.L> rose 5.5 percent to a record 477,766 ounces, while its gold and silver-backed products also recorded inflows. [
