Listen to this article Share African economies received a net $99.44 billion upward revision to their estimated Gross Domestic Product (GDP) between April and October 2026, even as renewed conflict involving Iran threatens to raise energy costs, fuel inflation and weaken growth prospects across the continent.

A comparison of the International Monetary Fund’s (IMF) April and October editions of its World Economic Outlook (WEO) shows that GDP estimates increased in 34 of 52 African countries covered, while 18 recorded declines.

Guinea recorded the largest upward revision, with its estimated GDP rising by $15.38 billion to $45.31 billion. Algeria followed with an increase of $14.65 billion, while Egypt’s estimate rose by $13.24 billion.

Ghana recorded a $10.35 billion increase, followed by Nigeria at $9.3 billion, Zimbabwe at $9.21 billion and South Africa at $9.12 billion.

The upward revisions totalled $121.38 billion, while downward revisions amounted to $21.94 billion, leaving a net increase of $99.44 billion across the countries analysed.

However, the upward revisions come as the renewed Middle East conflict creates fresh risks for African economies, particularly through higher oil and gas prices, shipping disruptions, food costs and pressure on currencies.

The IMF’s October regional outlook projects sub-Saharan Africa’s economy to grow by 4.5 percent in 2026 and 2027, but warns that the regional outlook masks significant differences between resource exporters and economies more exposed to higher import costs.

Oil-importing, non-resource-intensive economies face greater pressure from rising energy and food prices.

The revisions do not establish that the Iran war has improved or weakened the estimated GDP of the countries covered. Instead, they show how the IMF’s assessment of their economic size changed between releases, against a backdrop of increasing geopolitical uncertainty.

Guinea recorded the largest upward adjustment in dollar terms, with its estimated GDP rising from $29.93 billion in April to $45.31 billion in October, an increase of approximately 51.4 percent.

Algeria’s estimate rose from $317.24 billion to $331.89 billion, while Egypt’s increased from $429.65 billion to $442.89 billion.

Ghana’s estimated GDP climbed from $118.29 billion to $128.64 billion, while Nigeria’s rose from $377.37 billion to $386.67 billion. Zimbabwe recorded an increase from $56.71 billion to $65.92 billion, and South Africa’s estimate grew from $479.96 billion to $489.08 billion.

Ethiopia’s estimate increased by $5.62 billion to $127.15 billion, while Angola recorded a $4.9 billion rise to $157.3 billion. Libya’s estimate increased by $4.5 billion to $56.95 billion, and Kenya’s rose by $3.88 billion to $151.15 billion.

The scale of the revisions varied significantly. Guinea’s increase represented a much larger proportion of its initial estimate than the adjustments recorded by South Africa and Algeria.

These changes measure revisions to nominal GDP expressed in US dollars, rather than changes in real economic output. Exchange-rate movements, inflation, revised national accounts and changes in the IMF’s economic assumptions can all influence the estimates.

The renewed conflict presents an uneven challenge for African economies because the impact of higher energy prices depends partly on whether a country exports or imports fuel.

Oil exporters may benefit from higher crude prices through increased export earnings and government revenues, provided higher prices outweigh any production losses or export disruptions. Nigeria, Algeria, Angola and Libya could therefore face a different set of pressures from economies that rely heavily on imported petroleum products.

For oil-importing countries, more expensive fuel can increase transport and electricity costs, raise the price of food and manufactured goods, and widen trade deficits. These pressures can also put currencies under strain and complicate efforts by central banks to bring inflation down.

The IMF has warned that the Middle East conflict has disrupted energy markets and trade routes, with energy-importing economies facing higher import bills and limited fiscal and external buffers.

Even oil exporters are not automatically insulated. Higher fuel prices can feed into domestic inflation, while disruptions to shipping, production or regional trade can limit the benefits of stronger export prices.

The distinction matters because an increase in the dollar value of GDP does not necessarily mean households are better off. Higher nominal GDP can coexist with rising living costs, weaker purchasing power, and pressure on public finances.
