A War Africa Didn't Start: How the Hormuz Crisis Is Devastating Economies Across the Continent

There is a particular cruelty to the economics of global shocks: the countries that bear the least responsibility for a crisis frequently absorb the most damaging consequences. The 2026 Strait of Hormuz closure is proving no exception. Across sub-Saharan Africa, governments and ordinary households are confronting a sharp deterioration in living conditions driven by decisions made in Washington, Tel Aviv, and Tehran — none of which consulted a single African head of state.

The impact is not uniform. Africa is a continent of 54 countries with enormously varied economic structures, import profiles, and financial buffers. But from West Africa to East Africa to the Indian Ocean island states, the transmission mechanisms are consistent: higher fuel prices, weaker currencies, more expensive imports, and shrinking government fiscal space at exactly the moment when spending needs are rising.

The Fuel Price Shock

Most sub-Saharan African nations import refined petroleum products — petrol, diesel, kerosene, and aviation fuel — and pay for them in U.S. dollars at prices set by global markets. When Brent crude rises 40%, the dollar price of their fuel imports rises by a similar proportion. Their ability to absorb that increase depends on whether their currency has held its value against the dollar — and for most African currencies, it has not.

Nigeria's naira, which was already under significant pressure before the crisis, has fallen a further 8% against the dollar since the strait closed. Ghana's cedi has lost 11%. Kenya's shilling is at its weakest level since the 2022 IMF emergency drawing. The combined effect of higher dollar oil prices and weaker local currencies is devastating for retail fuel costs: Kenyan motorists are paying approximately 35% more per litre of petrol than they were six weeks ago. In landlocked nations like Uganda and Ethiopia, where fuel must be transported by road from coastal ports, the increase is even steeper when land freight costs are factored in.

Power Sector Stress

A significant proportion of Africa's electricity is generated from diesel and heavy fuel oil — particularly in West and Central Africa, where grid infrastructure is inadequate and many cities rely on distributed generation. Ghana, which has been navigating an electricity supply crisis for years, is facing renewed power cuts as the cost of fuel for its thermal generating plants has spiked beyond what its financially distressed utilities can afford. Nigeria's power sector — perpetually under-capitalised and heavily dependent on gas and diesel generation — is facing similar pressures.

In Tanzania and Mozambique, where large LNG projects were developed specifically to reduce dependence on oil-fired generation, the Hormuz crisis has paradoxically created new pressures by disrupting the global LNG market and raising the price of gas-related inputs and equipment. The benefits of energy diversification take years to materialise; the costs of the current crisis are landing now.

The Import Bill and Currency Pressure

For African governments that run significant current account deficits — importing more than they export — higher oil prices mean a larger deficit, more dollar demand, and more pressure on the currency. Most African nations do not have substantial foreign exchange reserves. Many were already accessing IMF facilities before the crisis; several are now in emergency consultations with the Fund about additional support.

The broader import inflation — not just fuel but also food, fertilisers, and manufactured goods all made more expensive by disrupted supply chains and higher freight costs — is landing in markets where household spending power is already thin. In economies where a significant share of the population lives on two to five dollars a day, a 20–30% increase in the cost of staple foods and fuel is not an inconvenience. It is a food security and poverty emergency.

Voices From the Ground

In Nairobi, small business owners who depend on diesel generators during power outages are describing costs that have made many operations unviable. In Lagos, transport operators have raised fares by 25–30%, adding to the inflation burden on workers who commute long distances. In Accra, construction projects dependent on imported materials have slowed or halted as costs become unmanageable. In Dar es Salaam, fishing fleets dependent on diesel have reduced operations, affecting both livelihoods and food supply in coastal communities.

These individual stories aggregate into a macroeconomic picture of considerable severity. The African Development Bank's preliminary estimate, released on March 15, suggests that the Hormuz crisis, if sustained for three months, will reduce GDP growth across sub-Saharan Africa by 1.2–1.8 percentage points in 2026 — enough to turn several fragile recoveries from Covid and Russia-Ukraine knock-on effects into outright contractions.

The Political Economy of Distant Wars

At the African Union summit emergency session convened on March 12, delegate after delegate made the same essential point: Africa is being made to pay for a war it had no role in starting, no power to prevent, and no voice in resolving. The AU's joint communiqué called for an immediate ceasefire and the reopening of the strait — not because African governments are natural allies of Iran, but because the economic consequences of the closure are landing hardest on the continent's most vulnerable populations.

That political argument — that the costs of great-power conflict are borne disproportionately by those with the least power — is one of the most consistent themes of the post-Cold War global order. It was true in 2022 when Russian missiles in Ukraine drove global wheat prices to record highs and triggered a food crisis across the Sahel. It is true again in 2026. The geography of suffering in this crisis, as in most, follows the geography of poverty — not the geography of fault.
