LONDON, March 4 (Reuters) - Gold retreated on Thursday from the 6-1/2 week high it hit in the previous session as the euro edged lower versus the dollar, but trading was subdued ahead of a European Central Bank announcement on interest rates later.
Spot gold <XAU=> was bid at $1,136.85 an ounce at 0955 GMT, against $1,139.35 late in New York on Wednesday. U.S. gold futures for April delivery <GCJ0> on the COMEX division of the New York Mercantile Exchange fell $5.80 to $1,137.50 an ounce.
Gold rose as high as $1,144.60 an ounce on Wednesday, its strongest since Jan. 15, as dollar weakness added to fears over the stability of the euro zone financial system to prompt buying of gold.
But the single currency's retreat from highs against the dollar on Thursday is putting the metal back under pressure.
"The pullback in the euro/dollar today is taking a little wind out of gold's sails," said Societe Generale analyst David Wilson. "There is still nervousness over the euro area, particularly with strikes in Portugal over austerity plans."
Fears over the outlook for a number of smaller euro zone economies, known as the PIIGS -- Portugal, Ireland, Italy, Greece and Spain -- have helped push the single currency down nearly 5 percent versus the dollar so far this year.
The euro gave back the gains made after Greece's latest austerity package encouraged investors, as risk-taking was subdued before central bank meetings in Europe and key U.S. jobs data on Friday. [
]The European Central Bank is seen keeping interest rates at a record low 1.0 percent, and is also expected to outline the next steps in its gradual withdrawal from emergency lending measures. [
]"The ECB (is) likely to signal some modest withdrawal of liquidity provision at its meeting today," said Credit Agricole CIB in a note.
OIL RETREATS
Among other commodities, oil prices slid towards $80 an ounce as the firmer dollar dragged prices off seven=week highs after news of another rise in U.S. crude inventories. [
]Gold tends to track crude prices, as the metal can be bought as a hedge against oil-led inflation.
On the wider markets, risk appetite was soft ahead of the ECB meeting and an interest rates announcement from the Bank of England, with European shares dipping from six-week highs. [
]Asian shares failed to hold on to early gains on Thursday, slipping lower as worries about Greece and the outlook for the global economy made investors cautious. [
]The world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD>, said its holdings stood at 1,115.511 tonnes as of March 3, up from 1,111.556 tonnes in the previous business day. [
]On the supply side, Russia's gold lobby said the country's gold output fell 59 percent in January from the previous month. Russia is the world's fifth largest gold miner. [
]Among other precious metals, spot silver <XAG=> was bid at $17.11 an ounce against $17.17, platinum <XPT=> was at $1,575 an ounce against $1,575.50, while palladium <XPD=> was at $456 against $446.50.
"Clearance of chart resistance at $1,594 in platinum and around the $450 area in palladium would open the way to re-test the January highs, as both metals gain further ground on increasing investment and industrial demand," said James Moore, an analyst at TheBullionDesk.com, in a note.
