The Bloomberg Dollar Spot Index, which tracks the U.S. currency against 10 major peers, fell 0.7 percent to 1,160.75 at 5 p.m. in New York, the lowest on a closing basis since Feb. 5. The index slid 3 percent in April.
The dollar weakened 1.4 percent to $1.1347 per euro and declined 0.3 percent to 119.46 yen.
“Long-term interest rates are at very low levels,” Yellen said in response to a question after a speech in Washington Wednesday. “We could see a sharp jump in long-term rates” after liftoff. Most Fed officials predict they will raise rates this year for the first time since 2006.
