LONDON, Nov 22 (Reuters) - Gold fell on Monday, as optimism over Ireland's request for financial aid was overtaken by concern about possible contagion to other euro zone nations to weigh on the euro.
The pick-up in the dollar undermined demand from investors for perceived safe-haven assets such as gold, which tends to struggle if the U.S. currency strengthens. [
]EU officials said Ireland may receive the first tranche of an emergency bailout in January and its debt problems are unlikely to spread to other euro zone nations, although Ireland's Green Party pulled the plug on the unpopular coalition government by calling for a national election. [
]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."
Spot gold <XAU=> traded at $1,352.50 an ounce by 1554 GMT, having earlier risen by as much as 0.77 percent to a session high of $1,364.55. U.S. gold futures for December delivery <GCZ0> were down 40 cents at $1,351.9.
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. [
]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, 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.
Meanwhile, China's steps to rein in inflation could dim gold's appeal in the world's second-largest consumer after India, but a drop in bullion prices from all-time high levels were attracting purchases from other consumers in Asia, local dealers said. [
]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 by 0.3 percent, rallying for a fourth successive day, after holdings of metal in the world's largest silver-backed ETF hit another record high. [
]Spot silver was last up at $27.29 an ounce, from $27.21 in late trade in New York on Friday, having risen by nearly 9 percent in the last five trading days.
Platinum <XPT=> was last down 0.65 percent on the day at $1,652.49 an ounce, while sister metal palladium <XPD=> was down 0.5 percent at $694.72 an ounce. (Reporting by Amanda Cooper; Editing by Michael Taylor)
