The dollar edged up on Monday, with an index that tracks the greenback against major currencies touching an 11-year peak even after soft economic data.
The euro, which is off nearly 10 percent in the last three months, had been up by as much as a third of a percent against the dollar on Monday but surrendered gains and last traded flat at $1.1192.
The yen went through 120 against the dollar for the first time since Feb. 12. The dollar was last up 0.50 percent to 120.09 yen, marking a three-week high for the dollar against the yen.
The dollar index was last up 0.14 percent at 95.427 after earlier going as high as 95.514, its highest since September 2003.
"The dollar's long-term trend is up but it now is in some consolidation," said Paul Christopher, international strategist at Wells Fargo in St Louis. "There is developing expectation Europe and Japan will improve their growth rates this year and that will narrow the lead for the U.S. economy."
