national-debt

The largest debt ratio is not automatically the biggest default risk. This guide separates gross, net, domestic, external and marketable government debt and explains interest costs, growth, refinancing and currency exposure.

Singapore and the United States carry the most gross government debt per person among high-income economies, yet the two cases mean very different things. This ranking explains per-capita debt, why debt-to-GDP and net debt often matter more, and what actually separates a manageable debt load from a crisis.

The US national debt passed $40 trillion in 2026. Whether that is a crisis or a manageable burden depends on interest rates, growth, and who holds the debt, and the answer is less obvious than either side claims.
