Developing Countries' External Debt Hits Record $9.4 Trillion in 2025, World Bank Warns of Access Crisis

The Quick Take

• External debt of developing nations surged 5.5% to a record $9.4 trillion in 2025, the fastest pace since 2021
• The pace of debt accumulation is roughly four times the 2022-2024 average, raising sustainability questions for frontier markets
• World Bank's International Debt Report 2026 flags limited access to international capital markets for many lower-income borrowers

The World Bank's International Debt Report 2026 reveals that developing-country external debt reached $9.4 trillion in 2025, a 5.5% single-year increase that marks both a record level and the fastest accumulation rate since the post-pandemic borrowing surge of 2021. The acceleration — roughly four times the pace recorded in the 2022-2024 period — signals that the combination of elevated global interest rates and persistent fiscal deficits has pushed many emerging and frontier economies into a refinancing trap just as new issuance costs have risen sharply.

The debt-load increase puts pressure on sovereign credit spreads for the most leveraged emerging-market borrowers, compressing the investment-grade corridor and raising the cost of new issuance. UAE-linked regional banks with significant Sub-Saharan Africa or South Asia trade-finance exposure may face incremental provisioning requirements. For GCC sovereign wealth funds, the report underlines the asymmetric risk of deploying capital into frontier-market debt instruments, while also creating tactical entry opportunities as distressed sovereign spreads widen.

Watch the IMF World Economic Outlook update for revised debt-sustainability analysis on the 25 most exposed developing economies — that framework is what determines special drawing rights allocations and bailout eligibility. The macro variable that determines whether this debt overhang becomes a contagion risk is the trajectory of US dollar strength: a DXY move above 108 would materially worsen the debt-service burden for dollar-denominated sovereign borrowers across Africa and South Asia, potentially triggering a wave of restructuring requests.
