Three African countries have a debt-to-GDP ratio above 100%, with Sudan at 238.8%

  • Sudan’s debt-to-GDP ratio of 238.8% is the highest in Africa and over twice the size of its economy.
  • Three African countries—Sudan, Cabo Verde, and Zambia—have debt burdens exceeding 100% of their GDP.
  • Egypt, Mozambique, and the Congo Republic follow closely with ratios above 88% each, despite efforts at economic reform.
  • Ghana and Sierra Leone are also in the top 10, showing that West Africa isn’t exempt from debt pressure.
  • Nigeria, while not in the top 10, has a debt-to-GDP ratio of 41.3% and ranks 43rd in Africa.
  • A high debt-to-GDP ratio often limits a country’s ability to invest in growth-driving sectors, even if the economy is growing nominally.

Africa's debt landscape remains a source of concern, with some countries now owing more than their economies produce in a year. As of 2024, Sudan leads the continent with a debt-to-GDP ratio of 238.8%, followed by Cabo Verde at 109.7% and Zambia at 100.8%. These figures suggest that while borrowing can be a tool for development, it can also signal deep fiscal imbalance, especially when not matched with productive investments or economic growth.

A closer look reveals that all of the top 10 most indebted African countries have debt levels exceeding 75% of their GDP. This high debt burden places pressure on public finances, leaving less room for spending on crucial sectors like health, education, and infrastructure. Even countries like Egypt and Mozambique, which have made strides in sectors like tourism and natural resource exports, still find themselves weighed down by heavy debts.

Interestingly, while some economies are struggling under high debt levels, others like Nigeria appear relatively stable in comparison, with a debt-to-GDP ratio of 41.3%. But this doesn’t tell the whole story, as it’s possible to have low debt ratios yet still struggle with revenue generation, debt servicing, or currency instability.
