It all depends on the data. For example, if US inflation comes in lower than expected next week, the tide could turn quickly. It's unlikely to happen today, however, as there is little meaningful data on the calendar. 

There are still a few central bank speeches to come, with ECB President Christine Lagarde's remarks at 13:30 GMT likely to attract renewed attention, although Lagarde is unlikely to have much to add to the market after a large number of speeches. Nevertheless, Powell's comments show that EUR/USD can still see significant market movement in the absence of major data points.
