Government Debt by Country (2026)

Global Government Debt Overview

Government debt as a percentage of GDP is the standard measure of fiscal sustainability — it tells you how much a government owes relative to the size of its economy. The global debt landscape has shifted dramatically since the 2008 financial crisis and especially since the COVID-19 pandemic, when governments worldwide borrowed trillions to fund stimulus packages, vaccine rollouts, and economic relief programs. Advanced economy debt-to-GDP ratios jumped from an average of about 70% before 2008 to over 110% by 2026.

Japan leads with government debt exceeding 227% of GDP — a level that would be unsustainable for most countries but is managed through Japan's unique combination of massive domestic savings, a persistent current account surplus, and a central bank that holds roughly half of all government bonds. The United States sustains debt above 120% of GDP because the dollar is the world's reserve currency and Treasury securities are the global safe asset. Greece, with similar nominal debt levels, required multiple bailouts because it couldn't print its own currency.

For emerging markets, the sustainability threshold is typically lower — the IMF considers debt above 60% of GDP a warning signal for developing countries because they face higher borrowing costs, greater currency risk, and more volatile capital flows. The key variables determining whether debt is dangerous are the interest rate paid on the debt versus the economy's growth rate, the currency denomination of borrowing, and the credibility of fiscal institutions. Countries borrowing in their own currency with independent central banks have far more room to maneuver than those borrowing in dollars or euros.
