NEW YORK, Sept 14 (Reuters) - The U.S. dollar fell broadly on Tuesday, breaking through milestone lows against the yen, euro and Swiss franc on a combination of political and technical factors while global stocks ended flat, taking little solace in upbeat U.S. retail sales data.
Safe-haven trades boosted gold to record highs and supported government debt prices. Oil fell.
The negative bias in stocks was seen carrying over into Japanese trade for Wednesday as the December futures contract for the Nikkei 225 stock index <0#NK:> trading in Chicago fell 50 points to 9,280.
In currency markets, the greenback stumbled to a 15-year low after Japanese Prime Minister Naoto Kan won an unexpectedly decisive victory in a ruling party vote. Markets were braced for a shift toward yen intervention if Kan lost the contest to a rival who argued more forcefully for a weaker currency.
The yen traded at one point below 83 per U.S. dollar and the euro hit a one-month high against the greenback, breaking above $1.30. The dollar sliced through parity against the Swiss franc, dropping to its lowest level since late November.
"It seems people are vacating dollar positions today and that money is shifting into other safe-haven assets for the time being -- the yen, the Swiss franc, gold and U.S. Treasuries," said Greg Salvaggio, vice president of trading at Tempus Consulting in Washington.
After a see-saw session, U.S. share prices ended mostly lower. The Dow Jones industrial average <.DJI> fell 17.64 points, or 0.17 percent, to 10,526.49. The Standard & Poor's 500 Index <.SPX> lost 0.80 point, or 0.07 percent, to 1,121.10. The Nasdaq Composite Index <.IXIC> dropped 4.06 points, or 0.18 percent, to 2,289.77.

European shares drifted lower into the close. The FTSEurofirst 300 <.FTEU3> index of top European shares ended the session down 0.03 percent at 1,087.63 in a choppy session after closing on Monday at its highest level since late April.

MSCI's All-Country World Index <.MIWD00000PUS>, however, edged up to a four-month high, gaining 0.34 percent.
Tokyo's benchmark Nikkei-225 stock index <.N225> finished down 0.24 percent.
YEN PLAY
The U.S. dollar fell 0.73 percent against the yen,
weakening to 83.07
Prime Minister Kan's victory over party heavyweight Ichiro Ozawa, who had made more strident calls to curb the yen's rise, raised speculation Japanese authorities would not intervene imminently.
The Kan victory provided "positive yen news," said Joseph
Trevisani, chief analyst at FX Solutions in Saddle River, New
Jersey. But he added that "83 has no more meaning than the
typical round number in dollar/yen. The level to look at is the
all-time low," which comes in around 79.75 yen.

Government debt prices were generally stronger in a flight-to-safety trade despite the U.S. retail sales report, which contrasted with a survey showing economic sentiment in Germany fell more than forecast in September. The ZEW survey turned negative for the first time since March 2009 and threw into doubt the economic recovery of Europe's largest economy. [ID:nLDE68C1RH]
