• The IEA declared the Iran war the largest oil supply disruption in market history, with Brent surging past $100 a barrel after the Strait of Hormuz shut down on Feb. 28
• African governments split into two camps: fiscally active (South Africa, Namibia) and fiscally constrained (Ethiopia, DRC, Kenya) — with Ivory Coast absorbing the shock via hidden subsidies whose cost remains undisclosed
• The food risk is the invisible threat: soaring fertilizer and shipping costs now threaten Africa's 2026/27 planting season — a slow-building crisis that may outlast the military conflict itself

African governments, stretched between depleted fiscal buffers and citizens facing record fuel costs, scrambled this week to contain the fallout from the worst oil supply disruption in global market history — one that has pushed Brent crude past $100 a barrel, driven up shipping costs for refined products, and threatened the region's next agricultural season before a single farm input has been ordered.

The trigger was the US-Israeli war on Iran that began Feb. 28, which prompted Tehran to close the Strait of Hormuz, a chokepoint through which roughly 20% of the world's daily oil supply transited before the conflict, according to data from the International Energy Agency. The IEA assessed the current episode as the largest supply disruption in the history of the global oil market, with flows through the strait collapsing from 20 million barrels a day to a fraction of that figure.

"This is bigger than COVID, bigger than the Russia-Ukraine war," said the head of Tanzania's petroleum industry association, speaking in an interview published March 21 by the Chanzo, a Dar es Salaam-based media outlet. "Within two weeks, oil prices jumped by more than 70 percent. That has never happened before."

The shock arrives at the worst moment for a continent where more than 40 economies import the bulk of their refined fuel, fiscal headroom remains narrow following debt restructurings and post-pandemic spending, and upstream infrastructure is too thin to allow governments to buffer consumers for long. The policy responses that have emerged since late February expose a continent fractured along lines of fiscal capacity — and reveal how few countries possess genuine shock absorbers.

Fiscal fractures

South Africa, the most industrialised economy in the region, delivered the most visible response. Finance Minister Enoch Godongwana cut the general fuel levy by $0.17 per liter from April 1 through May 5 — reducing the petrol levy from $0.24 to $0.06 per liter and the diesel levy from $0.23 to $0.05 per liter — according to a statement published on the National Treasury's website Tuesday. The one-month measure will cost around $349 million in foregone revenue, the government said. It did not prevent pump prices from rising: petrol still climbed $0.18 per liter on April 1, and diesel surged $0.44, according to figures released by the Department of Mineral and Petroleum Resources.

Namibia moved faster and deeper. The country's energy minister announced March 27 a 50% reduction in fuel levies for three months through the end of June, absorbing an estimated $29 million per month of under-recoveries through the National Energy Fund, according to a government statement issued in Windhoek. Even with the measure, petrol rose $0.15 per liter and diesel $0.23 on April 1.

Morocco, which imports more than 94% of its energy needs and operates without a functional domestic refinery, absorbed the shock through its fully liberalised pricing system. Diesel rose $0.20 per liter and super unleaded gained $0.14 on March 16 alone — a second hike in under two weeks — according to reporting by Le Matin and Médias24. Unlike its 2022 response to the Russia-Ukraine shock, the government offered no cushion on transport fuels.

Egypt, Africa's third-largest economy and among the continent's most indebted, chose a different arithmetic. The petroleum ministry raised domestic fuel prices 14% to 30% on March 10, yet the measure covered only about one-third of Egypt's actual energy cost increase, Prime Minister Mostafa Madbouly said at a cabinet press conference March 18, according to state television. Monthly natural gas import costs surged from $560 million to $1.65 billion. The government ordered shops, restaurants and malls to close by 9 p.m. on weekdays, cut street lighting and reduced fuel allocations for government vehicles by 30%.

Ivory Coast, West Africa's second-largest economy, held pump prices flat for March — super at $1.37 per liter, diesel at $1.13 per liter — through a state compensation mechanism active since 2017, according to a note from the General Directorate of Hydrocarbures published Feb. 27. The fiscal cost of that subsidy for the current period was not disclosed. Meanwhile, Ethiopia stands at the extreme end of the spectrum: authorities directed non-essential civil servants and state enterprise employees to take annual leave to reduce fuel consumption, as long queues formed at filling stations in Addis Ababa, according to reporting by Dawan Africa published March 30.

Food harvest risk

The agricultural threat embedded in the energy shock received less attention than pump prices but may prove more durable. The Gulf region accounts for a large share of globally traded urea, and the combination of higher gas prices and rerouted shipping has pushed fertilizer costs to levels that threaten African planting seasons for 2026 and 2027, according to an analysis published by Pan African Visions, citing research from the International Food Policy Research Institute.

Major shipping lines including MSC, Maersk, CMA CGM and Hapag-Lloyd suspended or rerouted Gulf and Red Sea services, adding emergency surcharges to food and fertilizer imports, according to company announcements. Hapag-Lloyd imposed a Peak Season Surcharge on all West African ports effective March 21, covering destinations from Dakar to Lagos, according to the carrier's published tariff notice. The cascading effect — higher freight costs feeding into food import prices, which in turn strain household budgets already compressed by fuel hikes — has received less political attention than the pump price debate, yet it may prove harder to reverse.

Nigeria, Africa's largest oil producer, illustrated the paradox facing the continent's exporters. Brent trading above $100 generated an estimated gross price premium of $55.5 million per day over the country's $64.85 budget benchmark — roughly $20 billion annualised — according to a March analysis by PricewaterhouseCoopers Nigeria. Yet crude-backed loan obligations and refinery supply contracts reduced the share of that windfall available to the treasury. With fuel subsidies removed in 2023, pump prices now track global crude directly: petrol surpassed 1,000 naira per liter in several states, according to Tribune Online, exposing households to the same transmission the subsidy once blocked. A presidential election is scheduled for January 2027.

Tanzania deployed the Tanzania Petroleum Development Corporation — the state oil company — to import fuel directly, bypassing the standard bulk procurement agency after the latter reported higher spot offers. The TPDC secured contracts at around $100 per barrel through direct negotiation with producers, locking in volume commitments through July, according to reporting by The Citizen published March 28. Combined stocks and incoming shipments gave the country 78 days of petrol cover, 50 days of diesel and 91 days of aviation fuel, the Petroleum Bulk Procurement Agency said at a ministerial briefing March 23.

The Democratic Republic of Congo, whose mining sector consumes diesel at scale across the Copperbelt and Katanga, adjusted prices in its southern supply zone on March 16, raising diesel from $1.70 to $2.43 per liter and petrol from $1.60 to $2.08, according to the country's Fuel Price Monitoring Committee. Mining companies have not received state fuel subsidies since July 2025 reforms — a direct threat to the competitiveness of Congolese cobalt and copper on global markets at a moment when demand for energy-transition metals remains high.

As the conflict enters its second month with no diplomatic resolution in sight, the next inflection point for African policymakers arrives in May, when South Africa's one-month levy reprieve expires, when Namibia reassesses its National Energy Fund drawdown, and when the first full wave of fertilizer price increases is expected to reach smallholder farmers ahead of the planting season. Godongwana said Tuesday he was still in discussion over what measures, if any, to extend beyond April — a signal that for Africa, the arithmetic of this crisis is far from settled.
