Why South Africa's Fuel Price Keeps Rising: How the Petrol Levy Works Explained
On the first Wednesday of every month, South Africans learn what they will pay for petrol that month. The price is not set by competing fuel stations — it is set by the government, and a single regulated price applies across the country with only small transport-cost adjustments for different zones. The Department of Mineral Resources and Energy (DMRE) publishes the new pump price, and every station in a zone must charge it. There is no shopping around for a cheaper fill-up the way there is in many other countries.
That monthly ritual is the visible end of a regulated pricing system built from two pieces: the Basic Fuel Price, which reflects the international cost of the fuel, and a stack of taxes, levies, and margins. Understanding those two layers is the key to understanding why the pump price rises even when South Africans change nothing about how they drive.
The Basic Fuel Price
The Basic Fuel Price (BFP) is the international component. It is calculated daily from the import-parity price — what it would cost to buy refined fuel on the global market, ship it to South African ports, and bring it inland. The calculation is done in US dollars and then converted to rand, which means the BFP moves with two things at once: the global price of refined petroleum products, and the dollar-to-rand exchange rate.
A weaker rand or a higher global oil price pushes the BFP up even if nothing else changes. Because South Africa imports a large share of its refined fuel, the country is a price-taker on the international market — local supply and demand barely influence the pump price. The BFP is the raw input cost before any tax is added, and it is recalculated every single day even though the pump price only changes once a month.
Taxes, Levies, and Margins
Stacked on top of the BFP is a set of government charges and commercial margins that together can account for roughly a third of the pump price. The General Fuel Levy is a tax paid into the national fiscus, and it has crept up over the years as a quiet revenue stream for the treasury. The Road Accident Fund (RAF) Levy funds the country's no-fault accident insurance system, under which anyone injured in a road accident can claim compensation regardless of who was at fault — a major and politically contentious cost that has grown rapidly and now makes up a significant share of every litre sold.
The Customs and Excise Levy applies to imported fuel. The Slate Levy is a temporary surcharge added when the regulated price has lagged behind the actual cost of fuel, allowing the regulator to recover accumulated under-recoveries from the public over time. On top of the statutory levies sit the regulated wholesale and retail margins — the fixed share that wholesalers and filling stations are allowed to earn for distributing and selling the fuel. These margins are set by the regulator, not negotiated, which is why two stations on opposite sides of a town charge the same price.
The Under- and Over-Recovery Mechanism
Because the pump price is fixed for a month at a time but the true import cost moves every day, the regulator runs a running balance called the slate. When the regulated price is below the actual cost, the difference accumulates as an under-recovery owed to the fuel industry; when it is above, an over-recovery accumulates in favour of consumers. Future pump prices are then adjusted to clear the slate, which is why price changes lag the market — a sharp move in oil or the rand shows up not immediately but in the following month's adjustment.
Why It Keeps Trending
Fuel is a politically explosive price in South Africa because it flows straight into the cost of living. Transport costs move into food, goods, and commuting, so a petrol hike feeds inflation within weeks. The RAF levy's steady growth draws regular criticism, and every monthly announcement is dissected for what it signals about the rand, global oil, and the government's fiscal choices. Global oil swings, rand weakness, and the rising cost of the no-fault accident fund have kept fuel near record highs, which is why the first Wednesday of the month never slips quietly by.
