The Strait of Hormuz shock is not just a distant geopolitical event for Africa; it is an
immediate economic transmission channel. From fuel prices to food costs, the effects are
already filtering through the continent’s most vulnerable pressure points.
The Strait handles roughly one fifth of global oil trade and a significant share of fertilizer
exports. As tensions escalated in late Q1, oil prices rose, and supply chains tightened,
triggering a chain reaction across African economies.

What this means for Africa
For oil exporters such as Nigeria and Angola, higher crude prices support export revenues,
fiscal balances, and foreign exchange inflows. But the broader continental picture is less
favourable. Nearly two-thirds of Sub-Saharan Africa’s GDP comes from net fuel-importing
economies, where rising oil prices feed directly into price pressures and inflation. Higher
fuel costs increase transport fares, raise business operating expenses, and push up food
prices in urban markets. For households, this shows up as a widening cost-of-living
squeeze.
