(Updates prices)

LONDON, Jan 12 (Reuters) - Gold eased on Wednesday after a successful Portuguese bond auction soothed some concern over the euro zone's finances and removed some investor desire for safe-haven assets, though a softer dollar stemmed the slide.
Spot gold <XAU=> was bid at $1,378.72 an ounce at 1610 GMT against $1,380.45 late in New York on Tuesday, having earlier risen as high as $1,386.90. U.S. gold futures for February delivery <GCG1> eased $5.80 an ounce to $1,378.50.
The metal has clawed back some lost ground after posting its biggest weekly loss since mid-2010 last week, as a focus on more positive U.S. data raised the prospect that U.S. authorities may curtail quantitative easing measures sooner rather than later.
However, in the absence of further bad news on euro zone sovereign debt and U.S. growth, it may struggle to build on last year's stellar performance, analysts said.
"Gold is being held because of uncertainty, and more than anything because of the fear factor that has been evident since the financial crisis," said Credit Agricole analyst Robin Bhar.
"As the economy strengthens, as financial markets normalise, and in the absence of any further shocks... that is one driver for gold that will start to unravel."
The euro rose for a third day against the dollar, although its gains were expected to be short-lived after the Portuguese debt sale did not fully dispell fears over the self-financing abilities of the euro zone's more fragile members. [
]While the auction did remove some of the need among investors for safe-haven assets, this persistent concern over the indebtedness of smaller euro zone economies is likely to continue to support gold, analysts said.
"With the euro still deep (in the) debt crisis and physicals using every dip to buy the metal on anticipation of an extended rise, there is little downside possibility for gold, at least in this quarter," said Pradeep Unni, senior analyst at Richcomm Global Services.
"Weakness in the dollar and rising oil will add to the...reasons to hoard gold."
OIL CLIMBS
Among other commodities, oil prices rose, with U.S. crude oil futures rising after a government inventory report showed crude oil stocks fell more than expected last week. [
]U.S. crude also rose to within a few dollars of its recent more than two-year high. Rising oil prices can fuel demand for commodities as an asset class, lifting gold.
Gold buying in top consumer India eased on Wednesday as prices rose, but buying remains strong overall across Asia, particularly in China. Premiums for gold bars hit their highest in two years on Tuesday. [
]"The impressive Chinese demand has been fuelled by lower prices, the upcoming New Year, and also physical delivery against the February Shanghai Futures Exchange contract," said UBS analyst Edel Tully in a note.
"We expect the heavy Chinese demand to persist for another 10 days or so, and turn very light in the five or six days before the Feb. 3 Chinese New Year, as seen in previous years."
Demand for gold to back exchange-traded funds eased off further, meanwhile, with holdings of the largest, New York's SPDR Gold Trust <GLD>, slipping just over 1 tonne on Tuesday. Its holdings have declined more than 9 tonnes since the start of the year. [
]Holdings of the largest silver ETF, the iShares Silver Trust <SLV>, also declined, to 10,725.73 tonnes on Tuesday from 10,786.51 tonnes. [
]Silver <XAG=> was bid at $29.54 an ounce against $29.50. Platinum <XPT=> was at $1,792.00 an ounce against $1,765.99, while palladium <XPD=> was at $799.97 against $782. (Editing by Alison Birrane)
