The IMF says output typically contracts by about 3% at the onset of war and continues to decline for years, resulting in cumulative losses of roughly 7% within five years in countries experiencing conflict.

Sub-Saharan Africa is facing mounting economic risks as global conflicts intensify, with new research highlighting how the war in the Middle East and rising defense spending are placing already vulnerable economies under severe strain.
According to analysis by the International Monetary Fund (IMF) in its upcoming April World Economic Outlook, the region stands among those most exposed to the long-term economic fallout of conflict, both directly and indirectly.
In countries experiencing conflict, the economic damage is immediate and persistent. Output typically contracts by about 3% at the onset of war and continues to decline for years, resulting in cumulative losses of roughly 7% within five years.
These losses often exceed those seen during financial crises or natural disasters, underscoring the uniquely destructive nature of armed conflict. For sub-Saharan Africa, where several economies are already grappling with structural challenges, the IMF said such declines can erase years of development gains.
The impact extends beyond the battlefield. Neighboring countries and key trading partners—many of which are in Sub-Saharan Africa—also experience economic spillovers.
Trade disruptions, reduced investment flows, and heightened uncertainty contribute to slower growth across the region. Even countries not directly involved in conflict face declining exports and weaker economic activity in the early years of nearby wars.
Fiscal pressures intensify significantly during conflict.
"Government budgets deteriorate as spending shifts toward defense and debt increases, while output and tax collection collapse. These countries may also face strains on their external balances. As imports contract sharply because of lower demand, exports decrease even more substantially, resulting in a temporary widening of the trade deficit," said the IMF economists.
"Heightened uncertainty triggers capital outflows, with both foreign direct investment and portfolio flows declining. This forces war time governments to rely more heavily on aid and, in some cases, remittances from citizens abroad to finance trade deficits."
The research shows that deficits can worsen by around 2.6% of GDP, while public debt may rise by as much as 7 percentage points within just three years.
Adding to these challenges is a broader global trend: rising defense spending. As geopolitical tensions escalate, many governments—including those in Africa—are reassessing security priorities. While increased defense spending can provide a short-term boost to economic activity, the long-term trade-offs are stark.
The IMF analysis finds that such spending often delivers only modest gains in output while significantly increasing fiscal vulnerabilities.
For sub-Saharan African countries, the implications are particularly difficult. Financing higher defense budgets often means either increasing debt or diverting resources from critical sectors such as health, education, and social protection.
These trade-offs risk undermining human development and long-term growth prospects. In regions where poverty and inequality remain pressing concerns, reduced social spending can have lasting societal consequences.
Even when peace is restored, economic rebounds tend to be slow and uneven. Output rarely returns quickly to pre-war levels, and the recovery is often driven more by the reallocation of labor than by gains in productivity or investment. In fragile states where conflict re-emerges, recovery efforts can stall entirely.
Effective recovery requires more than just the cessation of hostilities. The research emphasizes the importance of comprehensive policy responses, including macroeconomic stabilization, debt restructuring, and sustained international support.
Rebuilding institutions, restoring investor confidence, and facilitating the return of displaced populations are also critical components of long-term recovery.
The region’s economic trajectory will depend not only on domestic policy choices but also on the broader global environment. As conflicts persist and defense spending rises worldwide, African economies must navigate an increasingly complex landscape of risks and trade-offs.
