Poor countries are getting poorer faster The external debt of low- and middle-income countries will rise by 5.5% in 2025 to a record $9.4 trillion. The World Bank reports on this and notes that the cost of servicing the debt for the poor countries has reached a peak since 1989: the average interest rate on new private loans was 8.2%, and on bonds - 9.4%. At the same time, the growing debt burden leaves developing countries with fewer and fewer resources for long-term economic development.
