The euro fell another 0.6 percent, to trade under $1.38, still near the top of the ranges that have so concerned ECB policymakers in the past two months. It hit a peak of $1.3995 on Thursday before Draghi's comments, its highest since October 2011.
If the euro's strength has been this year's big surprise for markets, then it is largely in the context of the dollar's failure to make good on the raft of calls in January for it to strengthen.
Against the yen the dollar was little changed under 102 yen, still not far from a three-week low of 101.43 yen set on Wednesday. Likewise, sterling held steady near $1.69 within striking distance of $1.70—a level it has not broken since August 2009.
For the week, the greenback is down 0.5 percent against the yen, weighed down by persistently dovish comments from the Federal Reserve and low U.S. Treasury yields.
