Sierra Leone's macroeconomic performance in 2009 weakened due to the global economic slowdown. Real GDP is estimated to have slowed to 4 percent in 2009 from 5.5 percent in 2008. While lower fuel and domestic food prices eased inflationary pressures in the first half of 2009, the depreciation of the leone in the latter part of the year contributed to a rebound in inflation to 10.8 percent in December. In February 2010, inflation jumped to 17 percent, reflecting largely the challenges in implementing the new Goods and Services Tax in January, and higher domestic fuel prices. International reserves remained above 6 months of import cover.
