The CPI increased by 0.8% on a month on month basis.
Stats SA said this month’s figure is the highest annual inflation rate since September 2017 when it was at 5.1% as well.
The agency said South Africans paid 25.3% more for fuel in July 2018 compared with July 2017, the highest annual increase since December 2011.
The average price of 95 petrol inland has increased by R3.16/litre in the past year.
Food and non-alcoholic beverages inflation showed an annual increase of 3.4%.
Cold beverages registered annual inflation of 8.1% and bottled fizzy drinks increased by 2.7% from last month.
