For millions of South Africans, the petrol pump is about to become even more painful. Analysts warn that the country could see the largest monthly petrol price increase in at least 25 years, driven by global oil disruptions and rising local fuel taxes.
The potential spike is already causing concern among motorists, businesses, and transport operators who are bracing for another cost shock just as many households were beginning to feel some relief from inflation pressures.
Why petrol prices are suddenly surging
The biggest driver of the looming price increase lies far from South Africa. Global oil markets have been rattled by tensions in the Middle East, particularly around the Strait of Hormuz, one of the most important shipping routes for crude oil in the world.
Shipping activity through the Strait has largely halted amid escalating tensions in the region. Iran has threatened vessels attempting to pass through the area, and intelligence reports suggest parts of the Persian Gulf have been mined.
The impact is significant because about 20 percent of the world’s exported oil flows through this narrow route. When shipments are disrupted, oil prices tend to surge quickly.
As a result, Brent crude has been trading between $90 and $100 per barrel, with some analysts warning prices could climb even higher if the conflict drags on.
What this means for petrol and diesel in South Africa
South Africa adjusts its fuel prices monthly based on global oil prices and the rand-dollar exchange rate. With oil rising sharply, the numbers are now pointing to a major jump in April.
Current estimates suggest:
-
95 octane petrol could rise by about R3.70 per litre
-
93 octane petrol could increase by roughly R3.40 per litre
-
Diesel prices may surge by more than R6 per litre
If confirmed, this would represent the largest monthly petrol price increase in at least a quarter of a century.
To make matters tougher, fuel taxes are also scheduled to rise on 1 April. Both the General Fuel Levy and the Road Accident Fund levy will increase, pushing pump prices even higher.
For South Africans who rely on cars, taxis, or delivery services, the combined effect could be immediate and noticeable.
Based on current estimates, the increases could look like this:
| Fuel type | Estimated April increase | Notes |
|---|---|---|
| Petrol 95 | About R3.70 per litre | Could be the biggest monthly increase in at least 25 years |
| Petrol 93 | About R3.40 per litre | Driven by higher global oil prices |
| Diesel | More than R6 per litre | Diesel increase expected to be significantly higher than petrol |
The timing factor that could change everything
Despite the grim outlook, economists say the situation could still change quickly. Oil prices are known for their volatility, especially during geopolitical conflicts.
If tensions ease in the coming weeks and shipping resumes through the Strait of Hormuz, global oil prices could fall sharply again.
Some analysts believe that if the conflict is resolved soon, the current price spike might ease before South Africa’s fuel price adjustments fully reflect it.
However, at the moment, there are few clear signs that the situation in the Middle East will calm down quickly.
The bigger economic risk for South Africa
The real concern is not only the price motorists pay at the pump. Rising fuel costs ripple through the entire economy.
Transport becomes more expensive, which pushes up the cost of goods, food, and services. Economists warn that this could reverse some of the recent progress made in lowering inflation.
Estimates suggest that if oil prices remain around current levels, South Africa’s inflation rate could rise by roughly 1.2 percentage points.
That would push inflation closer to 4.5 percent, well above the central bank’s ideal target of around 3 percent.

What it could mean for interest rates
Fuel shocks often complicate decisions for the South African Reserve Bank.
Before the current global tensions escalated, expectations were building that interest rates might be cut again to support economic growth.
Now the outlook is more uncertain. If fuel prices push inflation higher, the central bank may decide to pause any planned interest rate cuts.
Economists currently believe the bank will likely hold rates steady rather than raise them, but future decisions will depend heavily on how long the global conflict lasts.

A difficult reality for South Africans
One of the most frustrating aspects of fuel price shocks is that local authorities have limited ability to soften the blow.
South Africa does not have a large strategic oil reserve, and the government does not have the fiscal capacity to subsidise fuel prices or reverse tax increases in a meaningful way.
In simple terms, the country remains highly exposed to global oil market shocks.
For many households already navigating high living costs, the coming months could bring another financial squeeze.
Still, economists point out that oil prices have always been volatile. What matters most is how long the disruption lasts and how businesses and consumers adapt to the higher costs.
For now, though, the message from analysts is clear. April’s petrol price adjustment could deliver one of the biggest shocks South African motorists have seen in decades.
