"In its widely anticipated decision to delay the end of QE past March, the ECB managed to cause some near-term confusion in currency markets. Even though the size of monthly purchases in the extended April-December 2017 period is going to be only 60bn euros, as opposed to the current 80bn, according to Mario Draghi that doesn't constitute a "tapering". So after initially rallying, the euro then ending up retreating again.

Whether this is a taper or not, the fact remains that the ECB's QE program hasn't been able to boost inflation, and failure to do so going forward keeps alive the very real possibility that the scheme will be extended again in the future.

Unless inflation starts to pick up, expect the euro to remain under pressure".
