Euro slips to one-week low after Yellen's speech

Euro fell on Friday to its lowest in a week after Yellen's speech, which forced the dollar to waver before returning higher and impacting the common currency. 

EUR/USD last traded at 1.1262, down from the opening of 1.1288, with a session-high at 1.1342, and a low at 1.1242. 

Fed Chair Yellen said the U.S. economy is on its way for the bank's target, which helped push the dollar higher as it raised prospects of a rate hike this year. 

Dollar was volatile however as Yellen didn't mention a specific date for the hike, but it firmed higher soon, impacting euro and other currencies negatively. 

The dollar index, which tracks the greenback against an array of six main currencies, rose to 94.88 from the opening of 94.69, with a session-low at 94.23, and a high at 95.04, after the index hit its highest this week at 94.95.
