Sovereign Debt Crisis Risk Monitor

Analysis of global sovereign debt levels, sustainability metrics, and potential triggers for sovereign debt crises

November 5, 2024 | Global Financial Markets Institute

Executive Summary

This report examines the current state of global sovereign debt and assesses the risk of sovereign debt crises across different regions. Despite stabilizing global debt-to-GDP ratios, our analysis reveals elevated risks in several emerging and developing economies, primarily due to rising interest rates, reduced fiscal space, and challenging refinancing conditions. Additionally, debt compositions in vulnerable countries highlight significant vulnerabilities to external shocks.

Key Finding #1

Interest payments now consume more than 20% of government revenue in five emerging economies

Key Finding #2

Advanced economy debt has stabilized but remains historically high at 114% of GDP

Key Finding #3

Ten countries are at high or extreme risk of debt distress in the next 12-24 months

Global Debt Trends

Global sovereign debt levels have stabilized in recent years, with aggregate debt-to-GDP ratios declining slightly from pandemic peaks. However, the absolute level of sovereign debt remains at historically high levels, particularly in advanced economies where it averages 114% of GDP.

Debt trajectories are diverging across income groups. While advanced economies have begun to stabilize their debt ratios, emerging markets and low-income countries have seen continuing increases in debt-to-GDP levels. This divergence reflects differing access to capital markets, varying economic growth rates, and different fiscal consolidation capabilities.

The composition of sovereign debt has also evolved, with increasing reliance on domestic currency debt in emerging markets (now 62% of total sovereign debt), though foreign currency exposures remain significant. Low-income countries continue to have high exposure to foreign currency debt (65%), creating significant exchange rate vulnerabilities.

Interest Payment Burden

Interest Payments as % of Government Revenue (2024)

Source: National treasury data, IMF Fiscal Monitor, October 2024

Rising interest rates have significantly increased the fiscal burden of sovereign debt, particularly for countries with large refinancing needs. Interest payments as a percentage of government revenue have reached alarming levels in several emerging and developing economies.

Ghana, Argentina, and Egypt face extreme interest payment burdens, with more than 18% of government revenue directed to debt servicing. This severely constrains fiscal space for essential public services and investment. Meanwhile, even advanced economies like the United States are experiencing rising interest burdens, with interest payments now consuming 12.4% of federal revenue.

The interest burden is particularly concerning when combined with weak economic growth prospects. Countries facing the "interest rate-growth differential" (where interest rates exceed economic growth rates) face debt dynamics that can quickly become unsustainable without substantial primary budget surpluses.

Risk Alert

Countries with interest payments exceeding 15% of government revenue face elevated risk of debt distress, particularly when combined with significant foreign currency exposure and near-term refinancing needs.

Debt Composition and Vulnerabilities

The composition of sovereign debt—including currency denomination, maturity profile, interest rate structure, and creditor base—is a critical determinant of vulnerability to debt distress. Our analysis reveals significant differences in these characteristics across country income groups.

Currency Risk

Low-income countries face significant currency mismatches with 65% of sovereign debt denominated in foreign currencies, primarily USD and EUR. Currency depreciation can rapidly increase debt burdens, creating fiscal stress and heightening rollover risks. Even emerging markets maintain substantial foreign currency exposure (38% of total debt).

Maturity Risk

Several emerging economies face concentrated maturity profiles, with significant debt redemptions due in the next 1-3 years. Brazil, Turkey, and South Africa all have more than 30% of their sovereign debt maturing within one year, creating substantial refinancing pressure in a higher interest rate environment. Advanced economies benefit from longer average maturities.

Creditor Composition

The shift toward non-Paris Club creditors, particularly for low-income countries, has complicated debt resolution frameworks. Official bilateral debt to non-Paris Club creditors now accounts for approximately 20% of external debt in low-income countries. This fragmented creditor base may complicate potential debt restructuring efforts.

Vulnerability Assessment

Our sovereign debt vulnerability assessment evaluates multiple factors including debt burden metrics, fiscal space, external position, debt composition, market access, and economic fundamentals to identify countries at elevated risk of debt distress.

The analysis identifies ten countries with high or extreme vulnerability scores, indicating significant risk of debt distress in the next 12-24 months. Ghana, Argentina, and Egypt demonstrate the highest vulnerability scores, with existing debt service challenges and limited market access.

A second tier of vulnerable countries—including Pakistan, Tunisia, El Salvador, and Kenya—face elevated risks but maintain some policy flexibility. These countries require careful monitoring, particularly as global financial conditions tighten and refinancing needs come due in 2025-2026.

Early Warning Signs

  • Sovereign bond spreads exceeding 1,000 basis points
  • Interest payments above 25% of government revenue
  • Short-term debt exceeding 30% of total debt with limited reserves
  • External financing needs above 15% of GDP
  • Primary fiscal deficits above 3% of GDP with debt/GDP exceeding 70%

Historical Context

Historical Sovereign Debt Crises

Source: Reinhart & Rogoff updated database, IMF, World Bank, 2024

Sovereign debt crises have become less frequent over recent decades, with the peak period of widespread defaults occurring during the 1980s debt crisis that primarily affected Latin America and parts of Africa. Institutional improvements, including stronger multilateral support frameworks and improved debt management practices, have contributed to greater resilience.

However, the current environment presents unique challenges compared to recent history. The combination of elevated debt levels following the pandemic, rapid interest rate increases, and a fragmented creditor landscape creates vulnerabilities that differ from previous periods of stress.

While institutional frameworks for dealing with sovereign debt crises have evolved, significant gaps remain. The Common Framework for Debt Treatments has shown limited effectiveness to date, and the rise of non-traditional creditors has complicated collective action approaches to debt resolution.

Risk Scenario Analysis

Scenario 1: Global Monetary Tightening Persists

Key Assumptions

  • Central banks maintain restrictive policy through 2025
  • Global 10-year yields increase 50-75 basis points
  • Emerging market currencies depreciate 10-15%
  • Global growth slows to 2.2%

Impact Assessment

Under this scenario, 3-5 vulnerable countries would likely experience debt distress requiring restructuring. Refinancing costs would increase significantly for all emerging markets, with yields for B-rated sovereigns increasing 150-200 basis points. Fiscal adjustments would accelerate across vulnerable countries, potentially creating social and political tensions.

Scenario 2: Commodity Price Shock

Key Assumptions

  • Oil prices decline to $50-55 per barrel
  • Metal prices fall 15-20%
  • Agricultural commodity prices decline 10%
  • Duration of shock: 12-18 months

Impact Assessment

Commodity exporters with already-weak fiscal positions would face severe stress, including Nigeria, Angola, Ecuador, and Zambia. Current account balances would deteriorate by 3-5% of GDP for major exporters. Credit ratings downgrades would likely follow for 6-8 commodity-dependent economies, restricting market access when most needed.

Scenario 3: Coordinated International Response

Key Assumptions

  • Enhanced Common Framework implementation
  • New IMF financing mechanisms for vulnerable countries
  • Coordinated creditor participation including China
  • Expanded concessional financing from multilaterals

Impact Assessment

A coordinated international response could meaningfully reduce near-term default risks and provide breathing room for fiscal adjustment. Bond spreads could compress 150-250 basis points for countries receiving support. However, underlying debt sustainability challenges would remain, requiring structural reforms and medium-term fiscal consolidation to restore sustainable debt trajectories.

Policy Implications and Recommendations

For Vulnerable Countries

  • Extend debt maturities where possible to reduce near-term refinancing needs
  • Develop comprehensive debt management strategies prioritizing sustainability
  • Implement gradual fiscal consolidation focused on revenue mobilization
  • Pursue structural reforms to enhance growth and export competitiveness
  • Engage proactively with creditors at early signs of unsustainability

For International Policymakers

  • Strengthen the Common Framework with clearer timelines and broader creditor participation
  • Expand precautionary financing facilities for countries with sound policies
  • Enhance debt transparency requirements and monitoring capabilities
  • Develop contingency plans for coordinated response to sovereign debt distress events
  • Implement standardized sovereign bond clauses to facilitate orderly restructuring

  • IMF program: $3 billion (2022)

Conclusion

The global sovereign debt landscape presents significant challenges, with elevated risks concentrated in a subset of vulnerable emerging and developing economies. While widespread sovereign debt crises are not our baseline expectation, pockets of severe stress are highly likely, with several countries facing debt restructuring needs in the next 12-24 months.

The combination of high debt levels, rising interest burdens, and challenging global financial conditions requires proactive policy responses from both vulnerable countries and the international community. Strengthening debt resolution frameworks and providing adequate support for countries implementing difficult but necessary adjustments will be critical to minimizing economic disruption and supporting financial stability.

"The current sovereign debt challenges require a balanced approach that addresses immediate liquidity needs while creating pathways to long-term debt sustainability through growth-enhancing reforms and prudent fiscal management."
