Renaissance Capital says Ghana’s GDP rebasing exercise exposes some underlying weakness in the West African country’s economy. Ghana changed its base year from 2006 to 2013 in its rebasing exercise, a move that led to a 25 per cent expansion of the GDP to 52 billion dollars, making Ghana the 6th largest economy in sub-Saharan Africa. Yvonne Mhango, Director and sub-Saharan Economist at Renaissance Capital joins CNBC Africa for this discussion.
