LONDON, Sept 23 (Reuters) - Gold fell on Wednesday, retreating from recent 18-month highs and taking cues from the dollar, with sentiment also capped by discomfort over the extent of long positions in futures markets and risk of liquidation.
Spot gold stood at $1,007.05 an ounce by 1440 GMT, down 0.65 percent from $1,013.80 quoted late in New York on Tuesday <XAU=>. Prices remain within striking distance of last week's 18-month high at $1,023.85 and the March 2008 historic peak at $1,030.80.
Gold and other markets, including stocks and currencies, traded cautiously ahead of the U.S. Federal Reserve's rate decision later in the day, with investors looking to see if the central bank repeats its intention to keep borrowing costs exceptionally low for an extended period. [
]Any resulting dollar weakness would boost gold's chances of trying to reach the record levels but as speculators hold record long positions -- buying to profit from upward price moves -- on the COMEX gold futures market, current price action is seen raising the possibility of a brutal bout of selling.
"If you add the ETF holdings to COMEX positioning at record highs, I think that might be a concern," VM Group analyst Matthew Turner said.
Last year, bullion lost more than $100 only a few days after it powered to the record high.
"We continue to view gold and silver prices warily due to large speculative long positions, although if the dollar remains weak there will be no correction," UBS metals analyst John Reade said ina note to clients.
ETF HOLDINGS STRONG
On currency markets, the dollar rose 0.2 percent against a basket of currencies including the euro at 76.169 <.DXY>. A stronger dollar makes commodities priced in the U.S. unit less attractive for non-U.S. investors.
U.S. gold futures for December delivery <GCZ9> lost $5.80 an ounce to $1,009.60 on the COMEX division of the New York Mercantile Exchange, having hit an intraday high of $1,020.40.
Silver <XAG=> fell to $16.81 per ounce from $17.10 in New York on Tuesday.
Platinum <XPT=> eased to $1,322.00 from $1,332.00 while palladium <XPD=> fell to $294.00 from 300.00.
The world's largest gold-backed exchange-traded fund, the SPDR Gold Trust, said its holdings stood at 1,101.735 tonnes as of Sept. 22, unchanged from the previous day.
ETF Securities said the amount of metal it holds to back its gold and ETFS Physical Palladium <PHPD.L> exchange-traded commodities rose to record highs in the week to Sept. 22. [
]The physical sector saw buying from main consumer India, but other consumers were hesitant.
"India continues to buy but I guess other consumers are quite cautious this time around. I don't think people dare to cash in right now especially after the market has bounced back from below $1,000," said a dealer in Singapore.
India's gold purchases have picked up as the festive season gained steam in the world's largest consumer. (Additional reporting by Lewa Pardomuan in Singapore) (Reporting by Veronica Brown; Editing by William Hardy)
