Closure of the Strait of Hormuz, the choke-point for roughly 20 million barrels of oil per day (around 20% of global consumption), would send an immediate shock through Africa’s fuel markets. Sub-Saharan African countries, many of which import most of their oil products, would face skyrocketing petrol and diesel prices. The International Energy Agency warns that around 600,000 bpd of refined fuel bound for Africa could be halted.
In east and southern Africa, where about 75% of fuels are shipped from the Middle East, the margin is razor-thin. For example, Kenya uses ~100,000 bpd and imports virtually all of it, while Ghana covers only about one-third of its 125,000 bpd demand from local refineries.
A Hormuz blockade would therefore hit consumers with higher pump prices and transport costs, fuelling inflation and straining government budgets. (Indeed, Africa as a whole imports roughly three times more oil products than it exports.)
Under these pressures, policymakers typically resort to quick fixes, such as expanding fuel subsidies, defending currencies and delaying capital projects, which often means postponing long-term investments in clean energy.
The pain would be uneven. Fuel importers such as Kenya, Ghana, Senegal and South Africa would suffer the largest shock from bigger import bills, higher inflation and tighter debt conditions. South Africa’s economy, for example, has already seen half its refineries idled, forcing heavy reliance on imports.
In these countries, any disruption in supply would quickly reverberate through transport, agriculture and industry.
Oil exporters like Nigeria and Angola might enjoy a short-term revenue boost from higher crude prices, but even they are not insulated. They too import some of their refined petrol and diesel, and higher global prices would worsen inflation and depreciate currencies.
In practice, higher fuel earnings often lead to populist subsidies or exchange-rate controls, not new infrastructure, undermining private investment. As Dr Charles Ojieh warns, succumbing to short-term politics only delays reform: by propping up fuel subsidies and postponing green projects, governments “postpone long-term investments” exactly when they are needed most.
Importantly, this crisis can sharpen Africa’s energy calculus. The continent is uniquely well endowed with renewables but woefully under-invested in them. Africa holds roughly 60% of the world’s best solar resources, yet today attracts barely 2–3% of global clean-energy investment. In fact, the IEA notes that Africa accounts for only ~2% of worldwide clean-energy spending despite about 20% of the global population.
Any sustained high oil price changes that dynamic: expensive diesel generators suddenly lose their cost advantage, making solar PV, battery storage, mini-grids and geothermal power far more competitive.
Clean energy is not just an environmental luxury; it is a strategic imperative. As one development expert observes, clean power “can lift millions out of poverty, driving inclusive industrialisation and economic growth”.
Conversely, “countries that continue to import volatility will keep exporting jobs, foreign exchange and resilience”. In short, if Africa keeps buying in volatile fossil fuel markets, it exports its own economic stability.
Evidence of this promise can be seen in the growth of renewables. Bright African sunlight (above) is ideally suited to photovoltaics and solar irrigation. Investments in solar and wind projects are rapidly falling in cost. Yet trillions more dollars are needed. For example, Financial Sector Deepening Africa reports that African green bond issuance is still under 1% of the global total.
Overall, the continent faces a financing gap: roughly $190 billion per year are needed for climate and clean-energy goals, but only about $44 billion is currently flowing. This shortfall underscores the urgency of new financing tools and the cost of inaction.
To bridge the gap and seize this moment, Africa must mobilise finance creatively. Ojieh and other experts argue that the Hormuz crisis should be treated as a financing stress test. Governments should unlock local capital by issuing more domestic-currency green bonds and de-risking investments with blended finance.
Agencies like UNCDF are already using concessional capital and first-loss guarantees to attract private investors into renewable projects. But markets remain shallow: an AfDB/UNCDF report notes that without strong credit guarantees and incentives, many projects are still deemed “high-risk”. Scaling these instruments could lower funding costs and crowd in global investors.
Meanwhile, practical projects must accelerate. Africa should “fast-track investment in mini-grids, solar irrigation, battery storage and regional power systems”. Expanded mini-grids and rooftop solar can quickly boost supply in rural and peri-urban areas, reducing demand for diesel. Interconnected national power pools (as under the African Union’s Single Electricity Market plan) can smooth supply and allow trade of surplus renewable power. Crucially, major existing assets should be used wisely.
Nigeria’s new 650,000 bpd facility Dangote refinery has already slashed the country’s fuel imports and begun exporting petrol to neighbours. (Billionaire Femi Otedola hailed it as ending Nigeria’s “economic slavery” to fuel imports.) Yet, Dr Ojieh cautions that such refineries alone are not enough. “Refining alone is not a long-term energy strategy,” he writes.
The real hedge against external shocks is diversification into renewables. In practice this means using assets like Dangote to relieve immediate shortages, while rapidly scaling clean infrastructure to build resilience for decades.
Key actions for African leaders are now clear:
Expand green finance. Treat the Hormuz shock as a wake-up call for capital markets – issue more local green bonds and attract blended finance, using credit guarantees to make projects bankable. African Development Bank and IFC initiatives point the way, but far more credit risk mitigation is needed to unlock global investors.
Accelerate renewables deployment. Fast-track solar, wind and storage projects at scale. Invest in irrigation powered by solar pumps, as well as off-grid mini-grids and battery storage to bring power to farming and industry. Overcome policy hurdles so that every community can harness its sun and wind.
Leverage strategic assets wisely. Use facilities like the Dangote refinery to cover shortfalls, but keep the long-term focus on clean energy. As Ojieh puts it, the true hedge against future oil shocks is not more refineries but “diversification towards energy transition”.
Africa’s choice is simple: remain vulnerable to imported oil volatility, or seize this moment to transform its energy sector. “Africa cannot build its future on imported fuel insecurity,” Ojieh argues.
The Strait of Hormuz crisis is a wake-up call that the era of fossil-dependent energy is over. If leaders respond with the courage and vision urged by Ojieh and embed renewables into core infrastructure, the continent can emerge with cheaper, cleaner power and greater economic resilience.
In a very real sense, this crisis could be the catalyst for Africa to finally treat renewables not as a side conversation, but as its energy foundation.
