In Africa, where trucks dominate the flow of products, farmers rely on fuel-powered gear, and many companies rely on diesel generators, a dramatic spike in diesel costs may swiftly spread across the economy.
This makes pricey diesel more than a transportation issue; it has the potential to raise food prices, squeeze companies, reduce industrial competitiveness, boost the cost of infrastructure projects, and put more strain on household incomes.

The disadvantages are increasingly clear as the global diesel market tightens.
In July, diesel shipments from Russia, the Middle East, and Asia declined by over 1.3 million barrels per day year on year, accounting for nearly 20% of global seaborne diesel commerce, according to data cited by Axios.
For African countries that rely largely on imported refined fuels, another extended period of high diesel costs might be especially painful.
Heavy trucks, buses, delivery vehicles, and construction equipment utilize a lot of diesel.
When fuel prices rise, transportation companies have few options but to absorb the additional cost, cut their margins, or pass it on to customers.
South Africa has already set a recent example, as the country's diesel prices rose in August, with industry and consumer organizations warning that increasing fuel costs might put extra strain on freight, food, and home budgets.
**The issue is especially relevant in Africa**, where road transit remains critical for connecting producers and consumers.
A farmer in a remote region still needs a truck to transport food to a city; likewise, a factory needs diesel-powered vehicles to transport raw materials and deliver finished goods.
High diesel costs can be extremely harmful for small and medium-sized enterprises.
In nations with inconsistent energy supply, companies frequently use diesel generators to keep stores, factories, cold rooms, offices, and workshops running.
That implies that any increase in diesel costs essentially raises the cost of energy for these enterprises.
With that said, here are the African countries with the most expensive diesel in August 2026, per data seen on GlobalPetrolPrices.
Compared to **last month’s list**, when the global average price of diesel was 1.50 U.S. dollars per liter, as opposed to 1.59 U.S. dollars per liter this month, diesel prices for Malawi, CAR, Rwanda, Seychelles, South Africa and Uganda surged.
While prices for Zimbabwe and Mozambique remained the same.
Lesotho replaced Kenya from the top 10 list this month.
