ACCRA (Reuters) - Ghana's annual inflation rate fell to 20.06 percent in May, down from 20.56 percent in April, the first fall in nine months but still above the 2008 peak of 18.4 percent, the Ghana Statistical Service said on Friday. Record high prices for oil and rising food prices pushed retail prices up last year and inflation in the gold and cocoa producing West African country has remained stubbornly high despite sharp falls in oil prices. |
