Diesel remains critical to African economies, as numerous commercial enterprises rely upon it to power transport fleets, heavy machinery, and auxiliary power generation systems.


Consequently, rising diesel prices can diminish profit margins and inflate the cost of essential consumer goods, whereas sustained price reductions afford meaningful economic relief.


An example of this was seen in Nigeria recently as the Dangote Petroleum Refinery reduced its diesel selling price by ₦80 to ₦1,700 per litre, a cut of about 4.5%.


It was the refinery’s second reduction in less than a month, following lower international crude and fuel-import costs.


Similar relief was expected in Ghana, where the Chamber of Oil Marketing Companies projected a 3.32% reduction in diesel prices from October 16, bringing the expected cash price to GH¢19.30 per litre.


The National Petroleum Authority also lowered its minimum diesel price floor from GH¢17.97 to GH¢17.09, as seen on MyJoyOnline.


These reductions matter because lower diesel costs can help logistics firms move goods more cheaply and give farmers more room to manage expenses during planting and harvesting seasons.


Businesses may also have more money available to invest in equipment, expand operations, or hire workers.


If transporters and retailers pass on some of their savings, the cost of moving food and other essentials could fall, easing pressure on household budgets.


However, cheaper diesel does not automatically translate into lower prices across the economy. Exchange-rate movements, electricity costs and other expenses can offset the gains.


For African countries, the bigger opportunity lies in making diesel more affordable and supply more reliable.


Sustained reductions can help businesses remain competitive, protect jobs and leave households with more money to spend.


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


Compared to last month’s list, when the global average price of diesel was 1.66 U.S. dollars per liter, as opposed to 1.67 U.S. dollars per liter this month, diesel prices for Libya, Algeria, Egypt, Tunisia, Gabon, Niger, and Madagascar reduced slightly.


Only Ethiopia experienced an increase during the month compared to September,


Diesel prices for Angola remained the same, while the DRC ousted Sudan from this month’s list.
