Zambia’s headline consumer inflation braked to 7.1% year-on-year in August, from 7.3% in July, mainly because of lower prices for food and non-alcoholic beverages, the statistics agency said on Thursday. On a month-on-month basis, CPI was steady at 0.7% in August. The southern African country’s trade surplus decreased to 94 million Zambian Kwacha (US$ 17m) in July, its lowest this year, from a revised 150m Kwacha in June 2013.
