Data & Discussion
The data for this visualization comes from the latest update by the International Monetary Fund (IMF) to their World Economic Outlook as of October 2025.

The IMF estimates the global average debt-to-GDP ratio at 94.7%, up from 92.4% the previous year.
While debt growth has slowed from the COVID-19 surge and high of 98.7%, elevated borrowing costs and sluggish growth are keeping public debt levels high.
Countries with the Highest Debt to GDP in 2025
At the top of the list, Japan holds a staggering 230% debt-to-GDP ratio, reflecting decades of fiscal stimulus and aging demographics.
Sudan (222%) follows, burdened by years of economic instability and conflict.
Singapore (176%), though high on the list, uses debt differently—largely tied to investment through its sovereign wealth funds.
Other high-debt countries include Venezuela (164%), Lebanon (164%), and Greece (147%), whose debt-to-GDP ratio has fallen significantly from its peak of 210% in 2020.
Government Debt in Advanced and Emerging Economies
Among advanced economies, average government debt stands near 113% of GDP, led by countries such as Japan (230%), Italy (137%), and the United States (124%).
In contrast, emerging markets average around 74%, with large economies like China (84%) and India (81%) driving much of the increase in recent years.
While emerging economies generally maintain lower ratios, rising global interest rates have intensified fiscal challenges, especially for nations reliant on external borrowing. |
