The dollar was on the defensive on Friday after soft U.S. economic data halted its advance against peers such as the yen and euro while the market awaited further developments in Greek debt negotiations.
The dollar index was at 94.195 after going to a one-week low of 93.979 overnight. The index had reached a two-week peak of 95.115 on Wednesday.
The dollar slipped 0.2 percent to 118.94 yen, knocked down from a five-week high of 120.48 touched on Wednesday after last week's robust U.S. non-farm payrolls revived prospects for a mid-year rate hike by the Federal Reserve.
Economic optimism was slightly cooled, however, by Thursday's weaker-than-expected U.S. retail sales and jobless claims. U.S. debt yields slid in the wake of the data, taking support away from the greenback.
"The slide showed that dollar/yen had become top-heavy and the market was simply unable to sustain earlier gains. The dollar still looks well supported, after all U.S. fundamentals, as nonfarm payrolls proved, remain relatively strong," said Koji Fukaya, president of FPG Securities in Tokyo.
"The global environment, on the other hand, does not fully support a 'risk on' mood and this impedes one-way gains by the dollar."
