This one is a closely watched indicator by many traders and current estimates have it come in at 1.5%. Germany is the biggest economy in the Eurozone and while the ECB is supposed to be independent many view it as the German Bundesbank in disguise.
Therefore any ECB policy will be in most cases Germany friendly which explains part of the problems in the Eurozone. As long as it remains below 2.0% the ECB, which happens to be located in Frankfurt, will be pleased on that front plus nobody expects the ECB to taper with interest rates anyway.
