It comes after a decrease in the petrol price this month.
Economist Ian Cruickshanks says the price of petrol could increase by 41 cents per litre.
A 30 cents per litre hike in the fuel levy will also come into effect in April.
“This is going to ripple through all sectors of the economy and slow it down even further. As far as consumers are concerned, food prices are going to have a very big impact.”
Efficient Group Chief Economist Dawie Roodt expects the overall increase to be closer to 80 cents a litre.
