Oil Markets Surge on Iran Tensions; African Importers Face Rising Fuel Costs

Brent crude futures settled at $86.19 a barrel on Tuesday, up $2.89 or 3.47%, their strongest close since June 12, after the United States reinstated a naval blockade targeting Iran. U.S. West Texas Intermediate added $1.53 to finish at $79.67, its best performance since June 16, just before Washington and Tehran signed a de-escalation memorandum on June 17. The catalyst: renewed supply anxiety over the Strait of Hormuz, the chokepoint through which a significant share of global crude exports flows. President Donald Trump’s proposal for a 20% fee on vessel passage through the strait layered additional cost uncertainty onto already jittery energy markets.

The price surge is landing differently across Africa, splitting the continent into clear economic winners and losers.

Oil-exporting nations stand to capture windfall revenues. Net importers, by contrast, face mounting pressure on foreign exchange reserves and consumer fuel costs. Kenya moved quickly to limit the damage, extending a reduction in value-added tax on petroleum products for three months through mid-October. South Africa’s currency weakened in early trading as investors weighed the Iran crisis alongside domestic mining data releases and closely watched U.S. inflation figures.

Blessing Odetokun, a Nigerian enterprise risk management officer, frames the crisis as something larger than a commodity price event. “This is a geopolitical crisis, not only for oil prices in Africa, but also for our economic resilience and strategic governance,” he told Forbes Africa. “Higher prices will intensify foreign exchange pressures and fuel inflation in net oil-importing countries, putting additional strain on consumers and supply chains.” Odetokun also cautioned that even oil exporters face complications: price volatility disrupts fiscal planning for governments whose budgets depend heavily on hydrocarbon revenues. His prescription is accelerated economic diversification and stronger risk management frameworks, particularly for Nigeria.

Folake Shakirah Lawal, Managing Partner and Principal Energy Analyst at Pan Allen Energy Nigeria, put the tension plainly. “Higher oil prices have always represented a double-edged sword for Africa. They can generate windfall revenues and stronger export earnings for producing countries, but many African economies remain exposed because they still rely heavily on imported refined petroleum products,” she explained to Forbes Africa. Lawal pointed to Nigeria’s 650,000-barrel-per-day Dangote refinery as a meaningful step toward reducing import dependence, while arguing the current crisis makes the case for expanded domestic refining capacity and deeper regional energy cooperation more urgent than ever.

The Dangote Group, controlled by billionaire industrialist Aliko Dangote, recently confirmed Kenya as the site for replicating its flagship Lagos refinery model in East Africa, a signal of confidence in regional market expansion even as geopolitical headwinds build.

Precious Ogbonna Onyedikachi, an energy analyst at the Nigeria Extractive Industries Transparency Initiative, suggested that sustained price increases could strengthen fiscal positions and currency values in African oil-producing economies including Nigeria and Algeria. Export earnings exceeding budgeted projections would give governments room to increase allocations to federal, state and local administrations.

Analysts caution that realizing those gains depends on how effectively governments manage windfall revenues, and whether price increases translate into sustained economic development rather than consumption or capital flight. Whether African producers can convert this price spike into durable fiscal strength, or whether volatility once again erodes the gains before they compound, is the question markets and policymakers will be watching through the months ahead.
