Top 10 African countries with the lowest diesel prices in May 2026

Diesel fuel is essential to the operation of many African countries. It powers transportation networks, agricultural productivity, and industrial activity, and offers backup power in areas with uncertain electricity supplies.

• The global average diesel price fell slightly month-on-month, dropping from $1.60 per liter to $1.57 per liter.
• Algeria, Egypt, Tunisia, Gabon, and Niger all recorded modest declines in diesel prices compared to last month.
• Ethiopia and Madagascar were the only countries on the list to see an increase in diesel prices over the same period.
• Diesel prices in Libya, Angola, and Sudan remained unchanged despite the broader global dip.

Because of this widespread dependence, even minor changes in diesel prices can have a significant impact on inflation, corporate expenditures, and consumer spending.

When diesel prices are stable or relatively low, the advantages spread throughout the economy.

Transportation costs become more predictable, food distribution becomes more efficient, and firms can better plan operations without experiencing unexpected cost shocks.

Lower diesel prices often reduce inflationary pressure, as logistics and energy costs are important components of ultimate consumer pricing.

This trend was apparent in Kenya in May 2026, when a significant spike in fuel prices sparked massive public outrage, including protests and a transportation strike that hampered economic activity in numerous major cities.

The fuel price increase, estimated at more than 20% in a single adjustment cycle, quickly led to higher transportation fares and rising costs for basic products, putting pressure on both households and companies.

The interruption demonstrated how closely diesel pricing is linked to daily life in Kenya, where public transportation, logistics, and agriculture are all strongly reliant on fuel affordability.

Following the turmoil, officials proceeded to lower diesel rates in the next pricing cycle, cutting costs by approximately 10 Kenyan shillings per litre as part of larger stability measures.

This intervention contributed to the restoration of transportation activity and the reduction of tensions, demonstrating how rapidly gasoline pricing changes can affect economic stability.

The Kenya episode demonstrates a bigger lesson for Africa: low diesel costs are not just an economic advantage, but also a social stabiliser.

When diesel is affordable, supply chains run more smoothly, food inflation is kept under control, and millions of people who rely on public transportation every day can continue to use it.

With that said, here are the African countries with the cheapest diesel in May 2026, per data seen on GlobalPetrolPrices.

Compared to last month’s list, when the global average price of diesel was 1.60 U.S. dollars per liter, as opposed to 1.57 U.S. dollars per liter currently, diesel prices for Alegria, Egypt, Tunisia, Gabon, and Niger all reduced slightly.

Prices for Ethiopia and Madagascar increased, while diesel prices in Libya, Angola, and Sudan remained the same.
