NEW YORK, Sept 8 (Reuters) - An advance in global stocks and commodities boosted investors' risk appetite on Tuesday, driving the U.S. dollar to its lowest in almost a year as trading volume picked up after the end of summer holidays in the United States.
A rally in gold prices above $1,000 and renewed concerns over the dollar's long-term status as the world's reserve currency, sparked by a United Nations report on Monday, also undermined demand for the greenback. [
]The dollar slumped to its lowest in almost a year against a basket of major currencies while the euro broke above a key options barrier at $1.4450 <EUR=>, traders noted. The U.S. currency, seen as a safe-haven in times of uncertainty, tends to fall when risk appetite increases.
"As we enter the first trading day after the summer, investors are decisively in risk seeking mode," said Camilla Sutton, a currency strategist at Scotia Capital in Toronto. Equities are strong, commodities have jumped higher and the dollar is noticeably weak."
The dollar index, which measures the value of the greenback against a basket of six major currencies, fell over one percent on the day to 77.14 <.DXY>, its lowest in almost a year.
The euro rose as high as $1.4507, according to Reuters data, up more than 1 percent on the day against the dollar and at its strongest since December. It was last up 1 percent at $1.4483.
Gold jumped more than 1 percent to $1,007.45 an ounce <XAU=>, its highest since March 2008.
Some in the market cited persistent talk this week that China could be diversifying a small part of its huge $2 trillion reserve stockpile into gold. Others noted that surging gold prices might encourage another wave of speculative dollar selling.
Currency analysts at Bank of Tokyo Mitsubishi said in a note that the daily correlation coefficient between gold and euro/dollar was 0.77 over the last six months and 0.70 over the last three months.
"Gold led the move higher in commodities and as it broke the key $1,000 level it helped push the dollar even lower," said Sutton at Scotia Capital. "We continue to believe that the dollar's downward trend will continue into year-end. Today's move may likely be the beginning of the next leg lower."
Sutton added the euro may trade at $1.50 by year end.
STOCKS ADVANCE
European shares rose for a third straight session, with the pan-European FTSEurofirst 300 index <
> edging close to recent 11-month peaks on the back of gold's rise and crude trading over $69 a barrel.Stock futures in the U.S. also pointed to a higher opening on Wall Street.
Rising share and gold prices helped lift the Australian and New Zealand dollars to their strongest levels in a year against the U.S. dollar.
The Aussie <AUD=> rose as high as $0.8647, its highest since August 2008. Data also showed Australia's business confidence hit a six-year high in August, adding to mounting speculation that local rates will rise in coming months, providing overall support to the Aussie.
The kiwi <NZD=> rose to a new one-year high of $0.6983, extending the previous session's gains.
