FOREX-Dollar at 6-week low, weighed down by soft data
* Dollar index at lowest since Jan. 1
* Japanese GDP below expectations, yen falls
* Euro supported by German, French data
* U.S. markets closed for Presidents Day
LONDON, Feb 17 (Reuters) - The dollar slipped to its lowest level since the turn of the year against a basket of major currencies on Monday as soft U.S. economic data stood in contrast to better figures out of the euro zone and China.
The dollar index fell as low as 80.065, its lowest since Jan. 1, and was last down 0.1 percent at 80.098. The euro touched a three-week high of $1.37245 and was last up 0.1 percent at $1.3702.
The greenback has been weighed down by recent soft economic data. On Friday, figures showed U.S. manufacturing output unexpectedly fell in January, prompting some commentators to question whether the Federal Reserve may slow the pace at which it cuts back its massive bond-buying stimulus.
Against the yen the dollar fell to its lowest since Feb. 6 but later recovered to trade up 0.1 percent at 101.89 yen after weaker-than-expected Japanese gross domestic product data.
"There's a general theme of dollar weakness," said Peter Kinsella, strategist with Commerzbank in London.
"There's been a very patchy data outlook for the past six weeks to two months and expectations of a rate rise from the Fed have been curtailed."
He said the data had not been soft enough for the Fed to slow its tapering, but warned that a fall in stock markets could hit the dollar against the yen.
"The fly in the ointment is equity market sentiment. It looks like a corrective bounce rather than a sustained leg higher. The long equity trade is very consensual, which is a risk for dollar-yen, which has moved in lock-step (with that)."
Japan's economy grew less than expected in the fourth quarter of last year as consumer spending, business investment and exports disappointed, in a worrying sign of waning momentum before a planned sales tax increase.
Investors initially reacted by buying the yen - typically seen as a safe haven - against the dollar, but Kinsella said the numbers were distorted by imports and were "misleading".
The latest data showed currency speculators pared bets on the U.S. dollar in the week ended Feb. 11.
Nevertheless, it was the 15th straight week in which speculators held net long positions in the greenback, reflecting a wider belief that the Fed will probably continue to wind back its extraordinary policy stimulus this year.
Volumes were thin in most currency pairs, with U.S. markets closed for Presidents Day and no major European data scheduled, although investors will keep an eye on a lecture by European Central Bank governing council member Ewald Nowotny on Monday.
The euro rose 0.1 percent against the yen to 139.58 yen , helped by data on Friday which showed both Germany and France grew slightly faster than expected in the fourth quarter, pushing the euro zone's recovery up a gear.
Commodity currencies such as the Australian dollar were also in favour after Chinese lending data on Saturday suggested the world's second biggest economy may not be cooling as much as feared.
However, analysts warned that the data could be distorted by the Lunar New Year holidays in January. China is the biggest export market for Australia and New Zealand.
The Australian dollar hit a fresh one-month high of $0.9070 , before ceding some ground to last stand at $0.9033.
