10 African countries with the highest diesel prices in June 2026

High diesel costs can have a substantial impact on African countries, particularly in nations where diesel is a primary fuel for transportation, manufacturing, agriculture, and energy generation.

• The global average diesel price fell from $1.58 per liter last month to $1.50 per liter this month.
• Malawi, the Central African Republic, Zimbabwe, South Africa, Lesotho, Zambia, and Botswana all recorded declines in diesel prices over the past month.
• Sierra Leone and Mozambique saw no change in their diesel prices compared to last month.
• Rwanda entered the list of Africa's 10 countries with the highest diesel prices this month, replacing Eswatini.

Because diesel is so firmly ingrained in supply chains, higher costs spread swiftly across numerous industries, putting a strain on the economy as a whole.

One of the most direct consequences of rising diesel prices is increased transportation costs. Diesel-powered vehicles play a critical role in road freight, public transportation, and logistics.

When fuel prices rise, the cost of carrying products rises, and these higher expenses are frequently passed on to consumers.

This raises the price of basic commodities, such as food and necessary home necessities, diminishing overall affordability.

In many African economies, supply networks are extremely vulnerable to diesel prices.

As operational expenditures rise, corporations generally raise prices to preserve profit margins.

This creates a cycle in which rising diesel costs feed into broader inflation, lowering household spending power and putting pressure on wages, which may not grow at the same rate.

Expensive diesel also has an impact on industrial productivity, as the manufacturing, agriculture, and construction industries rely on diesel-powered machinery for production and operations.

When diesel prices rise, businesses may limit output, postpone growth plans, or curtail investment in equipment and manpower. Over time, this can stifle economic progress and restrict competition.

Energy access is also affected, especially in areas where diesel generators are employed as backup power sources.

High fuel costs make it more expensive for companies and people to produce their own electricity, raising the risk of decreased productivity during power outages or system instability.

Small and medium-sized businesses are frequently the most impacted. With small financial buffers, they are more exposed to increased operational expenses and may struggle to remain profitable in a context of high fuel prices.

In general, high diesel prices exacerbate economic stress, raising inflation, lowering competitiveness, and restricting development potential across African nations.

With that said, here are the African countries with the most expensive diesel in June 2026, per data seen on GlobalPetrolPrices.

Compared to last month’s list, when the global average price of diesel was 1.58 U.S. dollars per liter, down to 1.50 U.S. dollars per liter currently, diesel prices for Malawi, CAR, Zimbabwe, South Africa, Lesotho, Zambia, and Botswana all declined.

While prices for Sierra Leone and Mozambique remained the same. Eswatini was ousted by Rwanda from the top 10 list this month.
