Countries with the Highest National Debt 2025

Just as individuals or companies may make purchases on credit or take out a loan to boost their finances, national governments often borrow money to further their countries’ growth or well-being. When this happens, the money borrowed becomes part of that country’s national debt. Stated simply, national debt is the combined debt a country’s government owes one or more lenders, such as other governments, various corporations, or even private individuals (such as with treasury bonds). But which countries have the world’s highest national debt? The answer to that question merits a bit of explanation.

In terms of raw dollars, the country with the highest debt in the world is unquestionably the United States, whose national debt is more than twice that of any other country. However, the dollar amount of a country’s debt is usually considered not by itself, but in relation to the country’s overall gross domestic product (GDP)—which represents the country’s ability to pay back the debt. Measuring by debt to GDP ratio, Lebanon’s debt is the highest in the world, and the United States—which has the world’s largest economy and highest GDP—drops to spot 13.

Profiles of Select Countries by National Debt

Japan

Japan has the second highest percentage of national debt in the world at 256.3% of its annual GDP, according to 2024 data, just behind Lebanon at almost 358%. The Japanese economy experienced stagnation during the 1990s, which led to the government launching several initiatives, such as selling bonds and bailing out banks and insurance companies with low-interest credit, to help reboot the struggling economy in the 2000s. Banking institutions had to be audited, consolidated, or even nationalized.

While these actions arguably salvaged Japan’s economy, they also added greatly to the country’s national debt. Since that time, additional concerns such as the Great Recession of 2008, the 2011 Fukushima nuclear disaster, and the COVID-19 pandemic have complicated efforts to combat the country’s debt.

United States

The United States boasts both the world’s biggest national debt in terms of dollar amount and its largest economy, which resolves to a debt-to GDP ratio of approximately 118.73%. The United States’ government’s spending exceeds its income most years, and the US has not had a budget surplus since 2001. Perhaps surprisingly, the countries to which the US is most in debt are Japan, which itself has significant debt, and China, which is often viewed as the United States’ greatest economic competitor.

China

China’s national debt is currently about 15 trillion USD; however, because of China’s massive economy, the country’s debt is only 84.38% of its GDP. China’s current debt level is a significant increase from 2014, when the national debt was 41.54% of the country’s GDP. An International Monetary Fund report from 2015 stated that China’s debt was relatively low, and many economists have dismissed worries over the size of the debt both in its overall size and relative to China’s GDP. China currently has the world’s second-largest economy and the largest population, with approximately 1.409 billion people.

Russia

Russia’s debt ratio was one of the lowest in the world at 16.99% of its GDP in 2021—though the country’s war with Ukraine, which began in early 2022, has caused a slight increase in this ratio to 18.89%. As of 2024, this rate is 19.55%. Russia is usually one of the ten least-indebted countries in the world. Russia’s debt is at a total of just under 393 billion USD as of 2024 data, down from 424 billion USD two years earlier. Most of Russia’s external debt is private.
