IMF Warns Unrealistic Budgets Are Driving Wider Fiscal Deficits in Sub-Saharan Africa

Sub-Saharan African countries are facing growing pressure on their public finances as a new report from the International Monetary Fund warns that unrealistic budget assumptions are contributing to wider fiscal deficits across the region. The study highlights a persistent gap between what governments plan in their budgets and what they actually achieve in fiscal outcomes.

According to the IMF research covering 39 countries between 2021 and 2024, many governments rely on overly optimistic revenue projections while simultaneously exceeding spending targets, particularly on wages, subsidies, and other recurrent expenditures. These mismatches have led to higher-than-expected deficits, even when initial budget plans suggest tighter fiscal control.

The report also shows that while governments struggle to meet revenue targets, capital spending on infrastructure such as roads, schools, and hospitals is often the first to be reduced or delayed. The IMF notes that interest payments are also frequently underestimated, adding further strain to already stretched national budgets.

Beyond numbers, the findings point to deeper institutional challenges. Countries with stronger fiscal systems recorded smaller budget deviations, while those under IMF-supported programmes showed better discipline due to closer monitoring. In contrast, low-income and fragile states experienced larger gaps between planned and actual spending, with pre-election periods often worsening fiscal discipline.

The IMF further warns that these persistent slippages are not temporary but structural, reflecting weaknesses in governance, expenditure control, and planning capacity. In a related outlook, the Fund projects that the median fiscal deficit for Sub-Saharan Africa will rise to 3.2% of GDP in 2026, raising fresh concerns about debt sustainability and long-term economic stability across the region.
