NEW YORK, Sept 8 (Reuters) - The U.S. dollar fell to its lowest in almost a year on Tuesday after gains in global stocks fed into renewed risk appetite as trading volume picked up at the end of summer holidays in the United States.

Some analysts said the U.S. dollar may resume seasonal declines as volume increases after a brief period in which the greenback rose following upbeat economic indicators.

A rally in gold prices above $1,000 and 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. [ID:nL7696421].

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, earlier fell over one percent on the day to 77.04 .DXY, its lowest in almost a year.

The euro rose as high as $1.4530, according to Reuters data, its strongest since December. It was last up 1.1 percent at $1.4491.

Over the past 20 years, September has been the second weakest month of the year for the dollar against the euro on an average and median basis, with the December being the weakest, according to data compiled by RBS Global Banking and Markets.

"Today's price action may likely be the beginning of the next leg lower on the dollar," said Scotia Capital's Sutton. "It all started when gold led the move higher in commodities, and as it broke the key $1,000 level it helped push the dollar even lower."

Gold jumped more than 1 percent earlier to $1,007.45 an ounce XAU=, its highest since March 2008. Crude prices also rose sharply on the New York Mercantile Exchange and traded above $70 a barrel .
