Global Debt Crisis 2026: Countries with Highest Debt-to-GDP Ratios
The world has never been this deep in the red. Global government debt now exceeds $100 trillion, and the ratio of debt to economic output keeps climbing in most major economies. Ten countries stand out in 2026 for debt-to-GDP ratios that would make most finance ministers wince.

The Top 10: Debt-to-GDP Rankings for 2026
1. Sudan — ~270%
Years of civil conflict destroyed economic output while borrowing continued. Most of Sudan's debt is external and denominated in foreign currency. Debt relief discussions with the IMF and World Bank are stalled by political chaos.
2. Japan — ~260%
Japan breaks every rule. Roughly 90% of its debt is held domestically, mostly by the Bank of Japan and domestic pension funds. Tokyo borrows in yen, from its own citizens, at interest rates that stayed near zero for decades.
But the model is cracking. BOJ finally abandoned negative rates in 2024 and has been slowly normalizing policy. Even a 1% average interest rate means ¥10 trillion in annual interest — roughly 20% of the national budget.
3. Eritrea — ~170%
Eritrea is one of the most isolated economies on earth. Most of the debt is owed to foreign creditors, including China, and the government lacks the foreign exchange earnings to service it.
4. Singapore — ~168%
Singapore looks alarming on paper, but the number is misleading. It borrows heavily to fund its Central Provident Fund — a mandatory savings scheme — and to finance long-term infrastructure. It runs persistent budget surpluses and holds enormous foreign reserves. Authorities could pay it down quickly if needed.
5. Greece — ~162%
Greece is the cautionary tale of the 2010s eurozone crisis. Bailouts in 2012 and 2015 restructured debt and imposed brutal austerity, but the ratio never fell below 150%. Greece is locked into a high-primary-surplus target until 2060 under its bailout agreements.
6. Italy — ~137%
Italy's debt is the sword of Damocles hanging over the eurozone. Rome owes roughly €2.8 trillion. Growth is the problem: Italy's economy has barely expanded in real terms since 2000.
7. Barbados — ~120%
Barbados restructured its debt in 2018–2019 in one of the most transparent sovereign defaults in recent history. The swap slashed debt service burden. Tourism rebounded strongly, helping the economy grow. Barbados is proof that default and restructuring can work.
8. United States — ~123%
America's debt has doubled since 2012. Annual deficits now run between $1.5–2.0 trillion, adding roughly 5–7 percentage points to the debt-to-GDP ratio each year. Interest on the debt now exceeds $1 trillion annually.

9. France — ~111%
France has the dubious honor of being the eurozone's second-most-indebted large economy. The deficit remains wide despite pension reform. Political risk is the real concern: if a future government promises spending without offsetting savings, investors could demand a steeper risk premium.
10. Belgium — ~106%
Belgium's debt burden is inherited from decades of fiscal laxity. Its saving grace is a high household savings rate and a current account surplus.
Why Debt-to-GDP Is Not the Whole Story
Currency matters. Japan and the US borrow in their own currencies. They can never be forced into default by a currency crisis. Argentina borrowed in dollars — and when the peso collapsed, default followed quickly.
Growth matters. A country with 5% real GDP growth and 100% debt-to-GDP can outgrow its debt. A country with 0% growth and 80% debt is in deeper trouble.
Who holds the debt matters. Domestic holders are stickier than foreign ones.
Interest rates matter most of all. Italy's debt was sustainable at 1% rates. At 4%, the same debt load requires much larger primary surpluses.
The 2026 Risk Map
Sudan and Eritrea are already effectively in default. Greece and Italy are on watch — both depend on ECB policy staying accommodative. Japan is the slow-burn risk: BOJ's exit from ultra-loose policy is the most important monetary experiment of the decade. America is not at imminent risk, but the trajectory is unsustainable.
What Investors and Citizens Should Watch
Three indicators tell you more than the headline ratio:
- Debt service costs: In the US, approaching 15% of the budget. In Japan, roughly 20%.
- Primary balance: Is the government running a surplus before interest? Italy and Greece run small primary surpluses.
- Real interest rates vs. real growth: If the real rate on debt exceeds real GDP growth, the debt ratio rises automatically.
