Announced last week, the ECB's new strategy allows it to tolerate inflation higher than its 2% goal when rates are near rock bottom, such as now. This is meant to reassure investors that policy won't be tightened prematurely and boost their expectations about future price growth, which has lagged below the ECB's target for most of the past decade.
