NEW YORK/LONDON, Nov 22 (Reuters) - Gold was little changed on Monday as optimism over Ireland's request for financial aid was overtaken by concern about possible contagion to other euro zone nation, weighing on the euro.
The pick-up in the dollar against a weaker euro undermined demand from investors for perceived safe-haven assets such as gold, which tends to struggle if the U.S. currency strengthens. [
]"Obviously, there are concerns about weakness of the Irish government, but above and beyond that, what's weighing on gold is the U.S. dollar, which has strengthened," said Peter Buchanan, senior economist of CIBC World Markets.
Ireland's unpopular coalition government was near breaking point amid calls for an election, as European and IMF officials began thrashing out details of a rescue package for the debt-stricken country -- expected to total 80 to 90 billion euros -- on Monday. [
]Buchanan, however, said that falling 10-year U.S. Treasury yield provided underlying support for non-interesting bearing assets such as gold. [
]U.S. yields have risen recently amid a broad unwind of long positions that were taken ahead of the Fed's bond-buyback announcement on Nov. 3. Rising yields, a proxy of U.S. interest rates, usually weigh on gold.
Spot gold <XAU=> was up 0.1 percent at $1,355.20 an ounce at 12:06 a.m. EDT (1706 GMT), having earlier risen almost 1 percent to a high of $1,364.55. U.S. gold futures for December delivery <GCZ0> rose $2.50 to $1,354.80.
Back in May, when the problems surrounding the euro zone's debt burden became apparent, gold's traditional link to the U.S. dollar broke down as investors sought an alternative to the euro, although the same phenomenon has not materialized with this recent resurgence of concern over Europe's finances.
"(Gold has) come down a bit on the Irish news, the euro has come down. It's not really huge moves, it's because traders are uncertain whether the bailout will be a success," said Matthew Turner, an analyst with Mitsubishi.
"There are two things -- will the bailout be a success and how will gold prices react if it is ... It could go either way."
Risk aversion alone does not always drive investors into precious metals, especially if the broader commodities complex comes under pressure, sweeping bullion lower in the process, as has been the case in the last three weeks. <.CRB>
Holdings of gold in the world's largest exchange-traded fund rose for the first time in two weeks, indicating investors were delving back into precious metals, albeit cautiously. [
]US SPEC LONGS DROP
While holdings of metal in ETFs rose last week, speculators cut their holdings of gold futures, according to data from the U.S. Commodity Futures Trading Commission last week.
Total open interest in gold futures held by non-commercial players, or spec longs, which many in the market use as a gauge of speculative activity, staged its largest weekly fall since late July and has fallen in five out of the past six weeks.
"Much of the short-term froth is now dissolved - particularly from the gold market - but that doesn't mean the stage is set for a re-run of fresh highs," said UBS precious metals strategist Edel Tully.
"With Thanksgiving approaching, U.S. investors in particular may be inclined to reduce risk positions over the holiday period," she added.
Reflecting the concern among some investors about the rise in the gold price against a backdrop of an improving global economy, HSBC Global Asset Management said late last week it had cut its gold allocation in its Absolute Return Fund in half.
"We have ... taken the prudent course of action and halved our position in gold bullion to 6 percent to reflect the fact that we remain bullish over the long term but acknowledge that gold has run ahead of itself at a time when the diversification benefits have become less obvious," wrote HSBC fund manager Charlie Morris in a note to clients.
Silver <XAG=> rose 1.3 percent to $27.55 an ounce, rallying for a fourth successive day, after holdings of metal in the world's largest silver-backed ETF hit another record high. [
]Spot silver has risen by nearly 9 percent in the last five trading days on speculative buying after following a sell-off after U.S. commodity exchange CME Group <CME.O> rose silver margins sharply to reduce market volatility.
Platinum <XPT=> slipped 0.7 percent on the day at $1,650.74 an ounce, while sister metal palladium <XPD=> fell 2.1 percent to $683.95 an ounce. Prices at 12:13 p.m. EST (1713 GMT)
