Cape Town – South Africa’s September 2026 fuel-price outlook remains uncertain amid volatile international oil markets and renewed conflict in the Middle East.
Current projections point to a larger increase for diesel than petrol, although the outlook has improved compared with the start of August. A stronger rand and Brent crude remaining below $90 a barrel have helped ease pressure on fuel prices.
Diesel motorists and businesses could be particularly affected, as higher diesel costs typically increase expenses across transport, agriculture, construction and logistics, with possible knock-on effects on consumer prices.
The latest figures show Brent crude at $88.46 a barrel, while the rand is trading at about R16.19 to the US dollar.
The final fuel-price adjustments will depend on the Central Energy Fund’s (CEF) calculations and are expected to be announced at the end of August, with new prices taking effect from 1 September 2026.
