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 January 1, and was last down marginally at 80.134. The euro touched a three-week high of $1.37245 and was last up 0.1 percent at $1.3700.
