IN SHORT: The US Navy began a naval blockade of the Strait of Hormuz on April 13 after peace negotiations in Islamabad between the US and Iran collapsed without agreement. Brent crude jumped more than 7% to above $102 per barrel on Monday morning. African oil-importing economies including South Africa, Kenya, Egypt, and Morocco face immediate diesel and petrol price hikes. The IMF Spring Meetings begin this week alongside a Sub-Saharan Africa regional outlook due April 16.
The collapse of US-Iran peace negotiations in Islamabad on April 12 and the subsequent announcement of a US Navy blockade of the Strait of Hormuz, effective April 13, sent Brent crude above $102 per barrel in early trading on Monday and set African oil-importing economies on a direct collision course with a second wave of fuel price increases that will push inflation higher, widen current account deficits, and test the fiscal room that central banks across the continent have spent two years carefully rebuilding.
- Brent crude: up more than 7.2% to above $102 per barrel on Monday morning. Analysts forecast $110 to $130 per barrel in coming weeks if Hormuz traffic is meaningfully disrupted. The strait normally handles approximately 20% of global seaborne oil supply.
- The US Navy blockade is designed to stop ships entering or leaving the strait and to intercept vessels paying tolls to Iran, preventing Iran from monetising the waterway as a lever. This goes materially further than the previous ceasefire-and-deadline cycle and represents a new escalation phase.
- Africa fuel price impact is direct and rapid. South Africa’s diesel price, already up R7.51 per litre in the April adjustment cycle, faces a further R2 to R4 per litre increase in the May cycle if crude holds above $100. Kenya, Egypt, Morocco, and smaller fuel-importing economies across the continent face similar pressure within days as pump prices are adjusted to reflect international crude benchmarks.
- Nigeria and Angola are beneficiaries on the revenue side. Nigerian crude exports have already been redirected toward Asian buyers replacing Gulf oil trapped by the Hormuz closure, as confirmed by Oando CEO Wale Tinubu in a Reuters interview last week. The Dangote Refinery is running at capacity and has increased exports to African countries facing supply disruptions.
- The IMF Spring Meetings begin this week in Washington (April 14 to 18). The IMF’s Sub-Saharan Africa Regional Economic Outlook is due April 16 and will provide updated continent-wide growth forecasts incorporating the Iran war impact. The October 2025 forecast had Sub-Saharan Africa growing 4.2% in 2026. A downgrade is expected.
- Nigeria CPI data is due April 15. Markets are watching for signs that inflation is moderating or whether energy and food pressures are pushing it higher. Nigeria’s CBN had been making progress bringing inflation down from 23% in 2025, with the World Bank projecting 14.9% in 2026.
- South Africa mining production data for February 2026 is due from Stats SA today (April 14), following last week’s manufacturing contraction data. Any further weakness in mining would compound pressure on Q1 2026 GDP expectations.
- Afreximbank activated a $10 billion Gulf Crisis Response Programme to insulate African and Caribbean economies, financial institutions, and corporates from the impact of the conflict, providing emergency liquidity support to member states facing acute fuel cost and supply chain pressure.
The Hormuz blockade changes the calculus for African central banks and finance ministries in one fundamental way: the previous two-week ceasefire created a brief window where monetary easing remained plausible. That window is now closed. The Kenya CBK paused its rate-cutting cycle last week explicitly to monitor oil price second-round effects. With crude back above $100 and trending higher, the CBK pause is likely to extend through at least two more meetings. The SARB, which has barely cut rates this cycle due to structural South African inflation pressures, now faces a scenario where imported energy cost inflation re-accelerates even as domestic demand remains weak. That is a classic stagflation trap and it is one of the hardest monetary policy environments to navigate.
The Bigger Picture: The Strait of Hormuz has been the defining variable in African macroeconomics since late February 2026. Every oil-importing African government, central bank, and corporate finance team has been running scenario plans since the war started. The naval blockade materialises the worst-case scenario from those plans. The countries that emerge from this period in the strongest relative position will be those that have diversified energy sources, built strategic fuel reserves, and used the last two years of lower rates to refinance government debt at better terms. Countries that did none of these things, and there are many, will face a compound crisis of higher import costs, weaker currencies, and constrained fiscal space, all at the same time.
