LONDON, Nov 15 (Reuters) - Gold held near $1,370 an ounce on Monday, steadying after its biggest one-day fall since July 1 in the previous session, as concerns over euro zone sovereign debt levels offset pressure exerted by strength in the dollar.
Spot gold <XAU=> was bid at $1,372.70 an ounce at 1614 GMT, against $1,366.35 late in New York on Friday. U.S. gold futures for December delivery <GCZ0> rose $6.70 to $1,372.20.
The metal staged its largest one-day drop in 4-1/2 months on Friday, retreating from last week's record $1,424.10, on concern the market had become overbought and as talk of a potential interest rate rise in China knocked commodities sharply lower.
"Beyond the short term correction in the gold price, the environment remains very positive for the metal," said Anne-Laure Tremblay, an analyst at BNP Paribas.
"Demand for gold is broad-based and is unlikely to falter next year, notably due to low interest rates, ample liquidity, inflationary concerns (particularly in Asia), issues relating to euro zone periphery countries and a weakening dollar."
Concerns over euro zone debt levels pressured the euro <EUR=> on Monday, with the single currency hitting a session low after the Financial Times quoted the Portuguese finance minister as saying there is a high risk that Portugal will have to seek foreign financial aid. [
]A spike in the borrowing costs of peripheral euro zone members over the past weeks had raised concerns about their ability to cut debt. [
]German government bond prices fell on Monday, however, as some safe-haven flows were unwound on talk that Ireland may ask the European Union for aid to manage its debt crisis. [
]Ireland on Sunday did not rule out the possibility that it might have to turn to Europe to deal with its debt but said that no application had been made for assistance yet. [
]Commerzbank analyst Eugen Weinberg said newly resurfacing worries over the stability of certain euro zone economies were "definitely helping" the metal. "That is the reason why we are not much lower," he said.
RISK AVERSION EYED
A stronger dollar typically weighs on gold, because it dents interest in the metal as an alternative asset and makes it more expensive for holders of other currencies.
However, when risk aversion rises sharply, as at the height of the sovereign debt crisis in the second quarter, they can move in the same direction as both serve as havens from risk. This may happen again if current euro zone debt fears worsen, analysts said.
"Jittery trading is likely to persist as long as uncertainty over Ireland haunts investor sentiment," VTB Capital analyst Andrey Kryuchenkov said in a note. "For bullion to rebound, risk aversion would need to sour completely and investor fears be confirmed."
He added: "For now, there could be more to the downside as we pull back towards the long-term uptrend."
Elsewhere silver <XAG=> was at $26.35 an ounce against $25.99. It underperformed gold on Friday to fall more than 6 percent, its biggest one-day drop since early February.
Among other precious metals, platinum <XPT=> was at $1,683.50 an ounce against $1,679, while palladium <XPD=> was at $681.97 against $675.50.
The chief executive of Lonmin <LMI.L>, the world's third-biggest platinum producer, said on Monday he sees the platinum market moving into deficit by about 2012 as the auto sector recovers further. [
]Meanwhile market participants said platinum demand in India may rise by more than 20 percent in 2011 from 10 tonnes now, driven by record sales by automakers, the biggest users, and as moneyed consumers spur jewellery sales. [
