After a sharp drop in 2009, because of lower world commodity prices, inflation picked up slightly in 2010 to an estimated average of 3.9%. In 2011-12 inflation is expected to fall to an annual average of 3.6% as a weakening euro has a deflationary impact on import prices. (France, Italy and Germany together provide one-quarter of imports.) There are serious questions about the reliability of data from the Central Administration of Statistics.
