Africa´s average inflation rate, which had declined to 7.7% in 2010 (from 10.1% in 2009), is expected to increase marginally to 8.4% in 2011 before sliding back again to 7.4% in 2012. The median inflation, which is not affected by countries with extremely high inflation, amounted to 4.7% in 2010 (down from 7.1% in 2009) and is projected to accelerate to 5.9% in 2011 before declining to and 5.3% in 2012. The main reason for the uptick of inflation rates in 2011 is the increase in energy and food prices. Among the 51 countries covered in this report, the majority will record inflation rates between 2 % and 5.5 % in 2011 and 2012. This is not excessive for developing countries in particular, as part of this price increase stems from higher import prices for food and energy so that core inflation is lower. But in some countries (such as Ethiopia, Sudan, Egypt and Angola) inflation is expected to remain above 10%.
