South African motorists are paying significantly more for fuel following sharp price increases that took effect on 7 October, with 95 petrol increasing by R3.33 a litre and diesel rising by up to R3.24 a litre.
The latest increase could put further pressure on households and businesses as higher transport and operating costs feed into the wider economy, according to Dr Christopher Ikechukwu Ifeacho, Lecturer in the Department of Public Management and Economics at Durban University of Technology (DUT) and a researcher in economic growth and development.
The latest adjustment means 95 petrol now costs R29.38 a litre at the coast, while the inland price has risen above R30 to R30.25 a litre. The price of 93 petrol increased by R3.12 a litre, while diesel prices increased by R2.84 a litre for 0.05% sulphur diesel and R3.24 a litre for 0.005% sulphur diesel.
The Department of Mineral and Petroleum Resources said the increase was largely driven by higher international oil and petroleum product prices. The average Brent crude oil price rose from US$87.89 to US$101 a barrel during the period under review, amid continued US-Iran tensions, uncertainty around oil flows through the Strait of Hormuz, higher shipping costs and lower inventories.
While motorists feel the impact immediately at the petrol station, fuel is an important input across the economy, affecting the movement of people and goods, agricultural production, business operations and household spending.
“Fuel is a fundamental input into almost every part of the economy. South Africa is particularly sensitive to fuel-price movements because goods, agricultural products, workers and services depend heavily on road transportation,” says Dr Ifeacho.
South Africa’s exposure to fuel-price movements is also influenced by international oil prices and the rand-dollar exchange rate, which affect the domestic cost of petroleum products. In the latest adjustment, the rand provided little relief, with the Department of Mineral and Petroleum Resources reporting only a marginal improvement in the average exchange rate during the period under review.
Higher fuel costs can put pressure on the transportation of goods from farms, factories, ports and warehouses to retailers and consumers. This is particularly important for the agricultural and food sectors, where diesel is used for farming activities, irrigation and harvesting, as well as the transportation of food.
However, Dr Ifeacho cautions that higher fuel prices do not automatically mean that food prices will increase by the same proportion.
“Food prices are determined by several factors, so fuel is one component of a much broader cost structure,” he explains.
The impact is also reflected in transport costs. In June 2026, Stats SA reported that transport was the largest contributor to annual and monthly consumer price inflation, while fuel prices had increased by 34.3% over the preceding 12 months.
For households, higher fuel prices can mean less disposable income as more money is spent on getting to work, taking children to school and meeting other essential transport needs.
The pressure is generally greater for low-income households because a larger proportion of their income is spent on essential goods and services. Middle-income households can also face additional pressure, particularly where private vehicles are necessary for daily commuting.
“Higher fuel costs can reduce real household purchasing power indirectly through the higher prices of other goods and services,” says Dr Ifeacho.
For students, the impact can be felt through higher taxi, bus and other transport costs, as well as rising prices for food and other essentials. Students who travel long distances to campus or rely on private vehicles may face additional pressure on their monthly budgets. Planning journeys, sharing transport where possible and managing spending carefully can help students navigate these pressures.
Businesses are similarly affected, particularly those in fuel-intensive sectors such as logistics, agriculture, mining, construction, manufacturing, retail distribution and passenger transport.
Diesel is particularly important for commercial activities because it powers many vehicles and machinery used to move goods and support production. As diesel costs rise, businesses may face higher operating and distribution costs, which can affect their margins and, in some cases, the prices paid by consumers.
A business facing higher fuel costs may absorb the increase, reduce its profit margin, improve efficiency or pass some of the additional cost on to customers. The impact can also reach businesses that do not use large amounts of fuel but depend on suppliers and service providers that do.
“This is why a fuel-price increase can have an economy-wide effect even on businesses that are not themselves large fuel consumers,” says Dr Ifeacho.
This wider transmission is one of the reasons fuel prices can contribute to inflation.
The direct effect comes from higher fuel prices themselves, while the indirect effect occurs as increased transport and production costs filter through to other goods and services. If the pressure persists, it can also influence wage demands and inflation expectations.
Annual consumer inflation reached 5.0% in June 2026, while fuel prices had increased by 34.3% over the preceding year.
The South African Reserve Bank’s October 2026 assessment has also highlighted the risk that persistent fuel, administered-price and food shocks could become embedded in inflation expectations and wages.
For households, Dr Ifeacho recommends reviewing spending and looking for practical ways to reduce fuel consumption, including combining trips, planning routes, carpooling and using public transport where possible.
Households should also consider the wider effect of higher fuel prices on food, transport fares and other expenses, rather than focusing only on the petrol bill.
“Most importantly, households should recognise that a temporary fuel-price shock and a sustained increase are different situations,” he says.
If higher fuel prices persist, households may need to make longer-term adjustments to their spending, commuting arrangements and vehicle use.
However, Dr Ifeacho says the broader response cannot rely on households alone.
“Reducing the economy’s vulnerability to fuel-price shocks requires greater transport efficiency, stronger public transport, improved logistics, energy diversification and policies that support productivity and competition,” he says.
Continued increases in fuel prices could also affect economic growth if households reduce spending and businesses face sustained pressure on their operating costs. The South African Reserve Bank’s October 2026 outlook projects economic growth of 1.2% for 2026 and expects inflation to remain above 5% until the second quarter of 2027.
Dr Ifeacho says South Africans should therefore distinguish between short-term fuel-price movements and a sustained shock that begins to affect broader prices and economic activity.
The key issue, he says, is not simply what motorists pay at the petrol station, but how long elevated fuel costs persist and how extensively they are transmitted through the wider economy.
For households, students and businesses, understanding these wider effects can help inform better decisions, while South Africa’s longer-term response will require greater transport efficiency, stronger public transport, improved logistics and greater diversification of energy sources.
