LONDON, March 3 (Reuters) - Gold rose to 6-1/2 week highs at $1,141.70 an ounce on Wednesday as the dollar extended losses versus the euro, and as broader fears over the outlook for paper currrencies lent further support to the precious metal.
Spot gold <XAU=> was bid at $1,138.25 an ounce at 1241 GMT, against $1,134.50 late in New York on Tuesday. U.S. gold futures for April delivery <GCJ0> on the COMEX division of the New York Mercantile Exchange rose $1.40 to $1,139.10 an ounce.
The metal held near the record highs it hit on Tuesday in euros and sterling terms, boosted by volatility in the foreign exchange markets.
"Gold is being used as a bit of an alternative to currencies," said Citigroup analyst David Thurtell. "It takes you out of dollar or euro exposure and puts you into a non-currency."
Gold is also benefiting from weakness in the dollar as it boosts gold's appeal as an alternative asset and makes dollar-priced commodities cheaper for holders of other currencies.
The euro extended gains against the U.S. unit on Wednesday to hit the day's high as a Greek government source cited details of fresh plans to tackle Greece's debt problems. [
]The Greek government endorsed a 4.8 billion euro austerity package, but markets were wary over whether it would be enough for Athens to win financial support from its European partners. [
]Concern over the fiscal health of peripheral euro zone economies like Greece, Italy and Spain have weighed heavily on the euro this year. It is currently down nearly 5 percent versus the dollar in 2010.
"The euro is oversold at the moment, but there is no guarantee that it does not have more downside especially given a quickly improving U.S. macro-economic environment," said VTB Capital analyst Andrey Kryuchenkov.
DAYA EYED
Traders are awaiting ADP U.S. employment data due later in the day, which is seen as a key precursor to Friday's closely-watched non-farm payrolls data for February.
"Markets will look to Wednesday's key ADP Employment Change survey data as well as the market-moving ISM Services report (at 1500 GMT)," said Richcomm Global Services senior analyst Pradeep Unni. "The U.S. non-farm payrolls report on Friday (will) be key data."
Among other commodities, oil climbed above $80 a barrel on Wednesday as the dollar weakened and investors looked ahead to a U.S. energy inventory report due later. [
]Elsewhere silver <XAG=> was bid at $17.11 an ounce against $16.92, having earlier touched a five-week high of $17.17.
The world's largest silver-backed exchange-traded fund, the iShares Silver Trust <SLV>, said its holdings fell 3.46 tonnes from the previous day to 9,473.45 tonnes as of March 2.
Platinum <XPT=> was at $1,576 an ounce against $1,566.50, while palladium <XPD=> was at $442 against $439.
U.S. auto sales stalled in February as a safety crisis sent Toyota Motor Corp <7203.T> <TM.N> reeling, allowing Ford Motor Co <F.N> to leap into the industry's top spot for the first time since 1998. [
]Both platinum and palladium are heavily exposed to the automotive sector, as they are primarily used in the production of autocatalysts.
