LONDON, Sept 24 (Reuters) - Gold prices tumbled on Thursday in a sell-off triggered by the dollar's rise after major central banks including the U.S. Federal Reserve announced plans to scale back some emergency lending facilities.
Spot gold <XAU=> fell to $992.60 an ounce, the lowest since September 15. It was bid at $997 at 1506 GMT compared with $1,007.05 late in New York on Wednesday.
The dollar recovered from earlier losses after major central banks announced plans to scale back massive injections of dollars into their banking systems in a sign that removal of monetary stimulus was already underway. [
]"The dollar bounced back and gold rose," said Michael Kempinski," a trader at Commerzbank. "It's a healthy correction ... some investors were disappointed that gold hasn't broken higher, but it did rise too fast."
A higher dollar makes commodities priced in the U.S. currency more expensive for holders of other currencies.
However prices remained within sight of last week's 18-month high at $1,023.85 and the March 2008 historic peak at $1,030.80.
"Dollar weakness is part of why we're sat where we are," Standard Bank analyst Walter De Wet said. "There's going to be more dollar weakness as we head towards the end of the year. So we see more upside in gold in the fourth quarter."
The precious metal hit a session high of $1,018.50 an ounce as the dollar fell against the euro after weekly data from the United States showed an unexpected fall in new claims for jobless benefits. [

HEDGE AGAINST RISK
Some analysts said gold would draw support from resilient demand in the physical market in Asia.
"Despite high prices physical demand seems to be recovering a bit," said Eugen Weinberg, an analyst at Commerzbank. "Together with higher investment interest, it's providing a good picture."
India's gold purchases have picked up as the festive season gathers pace in the world's largest consumer.
"At the moment we see signs of scarcity in some places," Weinberg said of the physical market in Asia. "It's surprising that some places need to wait some weeks for their deliveries."
The world's largest gold-backed exchange-traded fund, the SPDR Gold Trust <GLD>, said its holdings stood at 1,101.735 tonnes as of Sept 23, unchanged from the previous business day.
Among other precious metals, silver <XAG=> was bid at $16.28 from $16.71, platinum was at $1,303 from $1,318.5 and palladium at $290 from $292.
Traders said precious metals alongside other asset markets was waiting to hear the conclusions from the G20 summit in Pittsburgh on Thursday and Friday. [
