According to the International Monetary Fund, global debt increased from 229% of GDP in 2019 to 237% at the end of 2023 due to the pandemic, energy and food price spikes, and interest rates hikes by central banks in advanced countries. In Africa, the debt burden has become particularly severe. Half of African nations are now spending more on interest payments alone than on their public health budgets. This situation is unsustainable and disproportionally affects poorer countries.

In this episode of DebtTalks, Paola Subacchi and Jean-Pierre Landau discuss the constraints imposed by rising debt levels and the policy trade-offs among pressing needs such as poverty relief and climate action.
