Of the world's major economic powers, the United States has the highest national debt at 108.02% of its GDP. China, the world's second-largest economy and home to the world's largest population (1,415,045,928), has a national debt ratio of just 51.21% of its GDP. Germany, as Europe's largest economy, also has a relatively low national debt ratio at 59.81%. Hong Kong, a major global financial center, has the lowest national debt in the world, at just 0.05% of its GDP. This is followed by the tiny Kingdom of Brunei with a population of just 434,076 and a national debt of 2.49% of its GDP
