The International Monetary Fund (IMF) highlights that “Fiscal and structural reforms are key to reducing debt in sub-Saharan Africa” nations. The Washington based institution, recent country report, shows that these domestic policy actions have a much greater impact on the probability of a debt reduction episode than external factors like commodity prices or global demand.
This report comes as sub-Saharan Africa’s debt situation remains a significant concern. Public debt-to-GDP ratios have risen sharply over the past decade, driven by a series of global shocks and domestic challenges.
Average public debt-to-GDP ratio for the region stood at around 60.1% in 2023, up from roughly 50% in 2019. This means that for every dollar of economic output, countries in the region owe about 60 cents in debt.
The total external debt for the African continent as a whole reached approximately $1.2 trillion in 2023, with a significant portion of this owed by sub-Saharan African nations.
According to the IMF findings, the two most impactful factors are persistent fiscal consolidation and an improvement in the structural reform index.
- Persistent fiscal consolidation (steady efforts to reduce budget deficits) shows the highest probability of leading to a debt reduction episode.
- An improvement in the structural reform index (moving from the 25th to the 75th percentile) is the next most powerful factor. This indicates that reforms aimed at improving a country’s economic and institutional framework, such as strengthening financial markets or improving business regulations, are highly effective.
The IMF’s own support programs also play a significant role. An IMF program is shown to be a major contributor to increasing the likelihood of a debt reduction episode, underscoring the importance of international cooperation and policy support.

Meanwhile, external economic factors were found to have a much smaller effect on debt reduction. The chart shows that a 10-point increase in the commodity price index or a 1-percentage-point increase in global demand has a minimal impact on a country’s ability to reduce its debt.

This suggests that relying on favorable global economic conditions is not a reliable strategy for long-term debt sustainability.
The results provide a clear message to policymakers in sub-Saharan Africa: while external conditions can be helpful, the most sustainable path to reducing a debt burden that is now over 60% of GDP lies in committing to robust fiscal and structural reforms.
