Ghana Economic Outlook. Economic growth fell from 14% in 2011 at the onset of oil production to 3.5% in 2016, the lowest in two decades. The economy recovered in 2017, growing an estimated 6.3%, spurred by recovery in nonoil sectors, lower inflation, and new hydrocarbon wells (the Tweneboa, Enyenra, Ntomme, and Sankofa oil and gas fields).
