JOHANNESBURG - Economists are warning of sharp increases in fuel prices in April.
They blame it on rising oil prices due to the Middle East conflict.
Petrol and diesel prices are expected to jump by between R2 and R4 a litre.
It comes as Iran effectively blocks the Strait of Hormuz, which carries 20 percent of the global oil supply.

The war has already pushed Brent crude higher and added pressure on the Rand.
Economists warn that if oil prices rise further or the rand deteriorates, fuel hikes in April could be even higher.
Meanwhile, a 20 cent per litre petrol hike takes effect on Wednesday, adding immediate pressure on consumers.
