Rising global oil prices, a weaker rand and government levies continue to push petrol and diesel costs higher.
South African motorists are once again feeling the impact of rising fuel prices following the latest petrol and diesel price adjustments that came into effect in early March 2026. The increases have pushed petrol prices above the R20-per-litre mark in several inland regions, adding further strain to households and businesses already grappling with a rising cost of living.
The latest adjustment was announced by the Department of Mineral Resources and Energy, which regulates fuel prices in South Africa and reviews them on a monthly basis. From 4 March 2026, petrol prices increased by approximately 20 cents per litre, while diesel prices rose by between 62 cents and 65 cents per litre, depending on the grade.
As a result, motorists in inland provinces such as Gauteng are now paying about R20.19 per litre for 93 unleaded petrol and around R20.30 per litre for 95 unleaded petrol. Coastal regions, where transport costs are slightly lower, are paying about R19.47 per litre for 95 unleaded petrol. Diesel prices currently average around R19.17 per litre inland and approximately R17.84 per litre along the coast.
While the increases may appear modest, fuel price hikes have far-reaching consequences across the economy. Higher fuel costs affect not only motorists but also industries that rely heavily on transportation, including agriculture, logistics, public transport and manufacturing. As transport costs rise, businesses often pass these increases on to consumers through higher prices for goods and services.
One of the primary reasons behind the latest fuel price hike is the rise in international crude oil prices. South Africa imports a large portion of its petroleum products, making the country particularly vulnerable to changes in global oil markets.
In recent months, crude oil prices have climbed amid geopolitical tensions and supply concerns in key oil-producing regions. Conflicts and instability in parts of the Middle East, along with production decisions by major oil-exporting countries, have contributed to uncertainty in global energy markets.
When global oil prices rise, the cost of importing fuel into South Africa also increases. These costs are reflected in the Basic Fuel Price (BFP), which forms the largest component of the fuel price structure in the country. The BFP represents the international cost of refined petroleum products, as well as the cost of transporting them to South African ports.
Because the country does not produce enough crude oil to meet its own demand, South Africa remains highly dependent on international supply chains. This dependence means that global economic and political developments can quickly translate into higher fuel prices for local consumers.
Another key factor influencing fuel prices is the exchange rate between the South African rand and the US dollar. Oil is traded globally in US dollars, meaning that the value of the rand plays a significant role in determining how much the country pays for imported fuel.
When the rand weakens against the dollar, South Africa must spend more money to purchase the same quantity of oil. Even if global oil prices remain stable, a weaker currency can still lead to higher fuel prices at the pump.
Economic uncertainty, inflation concerns and global financial market trends can all influence the strength of the rand. When the currency comes under pressure, it often contributes to upward pressure on fuel prices.
In addition to international factors, a significant portion of the fuel price consists of government taxes and levies. These include the General Fuel Levy and the Road Accident Fund (RAF) levy, which together account for a substantial share of the price motorists pay at service stations.
These levies are used to fund government expenditure and to support the Road Accident Fund, which provides compensation to victims of road accidents in South Africa. However, critics argue that the high level of taxation on fuel places additional financial pressure on motorists and businesses.
Other components that contribute to the final pump price include wholesale and retail margins, storage costs, distribution fees and transportation expenses required to move fuel from coastal ports to inland regions.
Fuel price increases have broader economic consequences beyond the fuel pump. Transport costs play a central role in the pricing of many goods and services. When fuel becomes more expensive, businesses often face higher operating costs.
For example, farmers must spend more on diesel to operate machinery and transport produce, while trucking companies face higher costs when delivering goods across the country. These additional expenses can eventually lead to increased prices for food and other essential items.
Economists warn that rising fuel prices can contribute to inflation and further strain already tight household budgets. Public transport fares may also increase when fuel costs rise, affecting commuters who rely on taxis, buses and other forms of transport to travel to work.
Looking ahead, analysts caution that fuel prices may continue to fluctuate in the coming months. Early projections suggest that further increases could be possible if global oil prices remain elevated or if the rand continues to weaken against the US dollar.
International developments, including oil production decisions by major exporters and ongoing geopolitical tensions, will likely play a significant role in determining future fuel prices.
For many South Africans, the latest increase is yet another reminder of the country’s vulnerability to global energy market changes. As motorists continue to navigate rising fuel costs, the broader economic impact is expected to be felt across multiple sectors of the economy.
