Euro zone facing increased inflation volatility, Lagarde says

SINTRA, Portugal (Reuters) -Uncertainty is bound to remain a key feature of the global economy, likely making inflation more volatile and requiring the ECB to act more forcefully to keep prices around its target, ECB President Christine Lagarde said on Monday. The ECB unveiled an updated strategy on Monday and concluded that major deviations from its target in either direction would require "appropriately forceful or persistent" policy action to ensure price growth comes back to 2%.
