LONDON, Sept 22 (Reuters) - Gold climbed 1.5 percent to trade within striking distance of its all-time high on Tuesday, as the dollar fell across the board ahead of a Federal Reserve meeting on interest rates.
Spot gold <XAU=> rose as high as $1,017.40 an ounce and was at $1,015.90 an ounce by 1047 GMT, versus $1,002.55 an ounce late in New York on Monday, when it fell to $995.50, its lowest in almost a week.
Traders said further dollar weakness could trigger a rally which could send bullion above its 18-month high of $1,023.85 an ounce hit last week, and to within sight of the $1,030.80 an ounce record high struck in March 2008.
But lack of physical buying due to high and volatile prices, worries about a liquidation from speculators who have built extremely long positions in New York and the potential impact of an IMF gold sales plan have all capped further gains.
"It was a tough cookie to crack last week, and it still is," said Afshin Nabavi, head of trading at MKS Finance. "We need some fresh news to provide the momentum...I'm bullish but I think we need a more substantial correction than the one we saw yesterday," he said.
Some traders said the dollar weakness could give that boost.
"I find it difficult in the near term for gold to do anything independent from the dollar," said Ole Hansen, senior manager at Saxo Bank. "Gold will probably rally to a new record if we see a sudden burst of activity on the dollar," he said.
The IMF on Friday endorsed a plan for strictly limited sales of 403.3 tonnes of gold from its stockpile. [
]The euro rose above $1.48 for the first time in a year as dealers took advantage of deteriorating sentiment toward the dollar to target options barriers at that level.[
]The market watched for the outcome of a two-day Federal Reserve monetary policy meeting, which is due to start on Tuesday and a G20 meeting, which kicks off on Thursday, which could have an impact on the dollar.
LET THE STEAM OUT
The Federal Open Market Committee was expected to hold rates steady but markets want to know if there are signs that the policy stance will be wound back, given a recent pick-up in economic data. [
]But noncommercial net long positions in gold futures in New York at an all-time high of 235,647 lots for the week ended Sept.15 worried investors as it could spark a long liquidation. [
]"We need to see the previous record high broken to let some steam out of this market. As long as we fail to get through that level there's always the risk that we could see long liquidation on disappointment," Hansen at Saxo Bank said.
U.S. gold futures for December delivery <GCZ9> fell $9.30 an ounce at $1,014.2 on the COMEX division of the New York Mercantile Exchange.
But lower prices could attract buying from main consumer India, where weddings traditionally take place during the current festive season, which peaks in October with Diwali, the Hindu festival of lights.
"We need the physical market to come and obviously at these levels that market is very hesitant," Nabavi at MKS Finance said.
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 21, up from 1,086.479 tonnes the previous day.
In other metals, silver rose to $17.20 an ounce compared with Monday's $16.80, while palladium <XPD=> was at $299.50 an ounce versus $294.50 an ounce. It hit $304 an ounce last week, its highest since end-August 2008.
Platinum <XPT=> was at $1,328 an ounce compared with $1,315.50 an ounce.
