Speculation on when the Fed would hike rates took center stage last Wednesday when the central bank said it would remain "patient" on raising rates.
The U.S dollar has been climbing since mid-December and reached multiyear highs after the European Central Bank unveiled its nearly $70 billion monthly quantitative easing plan Jan. 22.
