10 African countries with the highest diesel prices in April 2026

The recent increase in diesel costs in various African countries without an immediate response could become more than a passing energy shock; it has the potential to morph into an economic threat with far-reaching effects.

Global tensions over the Iran conflict have disrupted fuel markets in recent weeks, driving diesel prices considerably higher.

Across Africa, the impact has been immediate and severe.

Countries such as Nigeria, Ghana, and Kenya have all seen significant increases in diesel prices.

While these developments may appear to be sector-specific, the reality is that diesel is central to most African economies, thus growing costs can have an impact on practically every level of economic activity.

Diesel is a primary fuel source used for transportation, heavy machinery, and backup power generation over much of Africa.

When the price of this essential energy product rises, businesses instantly feel the repercussions.

Rising prices immediately increase the cost of manufacturing and services in several nations across the continent, where diesel generators are commonly employed due to unpredictable energy.

As diesel costs climb, inflation usually follows.

The cost of transporting commodities, producing food, and running enterprises rises, and these costs are passed on to customers, ultimately harming the economy.

As a result, governments across the continent are frequently obliged to intervene in the form of fuel levy reductions and tax adjustments to mitigate the impact.

These treatments may bring temporary respite, but they come at a cost.

Reduced fuel taxes result in lower government revenue, which can have an impact on infrastructure, healthcare, and social services.

In such situations, governments may turn to subsidies, putting further burden on already tight budgets.

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

Compared to the figures last month, when the global average price of diesel was 1.43 U.S. dollars per liter, as opposed to 1.60 U.S. dollars per liter currently, diesel prices for Malawi, the Central African Republic, Zimbabwe, and Sierra Leone increased.

This month’s list has 6 new countries in the top 10, including Lesotho, Liberia, South Africa, Botswana, Mali, and Zambia.

These countries ousted Cameroon, Morocco, Guinea, Rwanda, Burundi, and Seychelles from last month’s list.
