The dollar has fallen against other major currencies due to a possible German aid to Greece's fiscal crisis and mixed US economic data.
The euro traded at 1.3620 dollars in New York trading on Friday, up from 1.3546 a day ago.
The greenback also dropped to 88.81 Japanese yen from 89.09 yen while, the pound bought 1.5248 dollars from 1.5246 dollars.
Speculations raised about Germany's plan to buy Greek bonds through state-owned lender KfW Group also pushed the value of euro up against other currencies.
