The EU's executive arm had previously estimated inflation at 1.8% for 2011 but said "a surge in energy and commodity prices in the last few months has led to an uptick" in the harmonised index of consumer prices.

"Should geopolitical tensions spread further in the Mena (Middle East-North Africa) region, disruptions to oil supply could not be excluded, fuelling oil-price increases beyond what is assumed in this forecast," it said.
