Geoeconomics and Its Impact on Sovereign Debt Risks: Lessons from the Past and Current Relevance
A study by Millennium Institute MIPP researcher Marcela Valenzuela explores how international political relations influence sovereign default risks and economic recovery after a crisis. The findings highlight the critical role of military cooperation and diplomatic integration in global financial stability.
A Growing Link Between Politics and Economics
In a world increasingly shaped by geopolitical tensions, the connection between international politics and economic stability has become more pronounced. A study led by Marcela Valenzuela from the Millennium Institute MIPP, alongside Consuelo Silva-Buston and Ilknur Zer, examines this link from a fresh perspective. Using data from 152 countries dating back to the 1880s, the researchers analyze how international political relationships affect sovereign default risks and economic resilience after financial crises.
The study contextualizes these findings within a global framework that includes major historical events such as the World Wars, the establishment of international institutions like the UN and NATO, and recent crises like the U.S.-China trade tensions. By integrating historical and contemporary references, the research illustrates how international politics shape capital flows and financial risks.
A Key Index: The IPR
The study, “The Geoeconomics of International Political Relations and Sovereign Defaults”, introduces the International Political Relations (IPR) Index, a tool that measures military cooperation, diplomatic integration, and political ties between countries. The index predicts sovereign default risk with accuracy comparable to traditional indicators such as the debt-to-GDP ratio or domestic political stability.
The IPR is built using data on military conflicts, alliances, diplomatic ties, and memberships in international organizations. For instance, countries with strong military alliances and fewer conflicts score higher, indicating greater political integration and lower financial risk.
Key Findings
📌 A Reliable Indicator: A higher IPR score reduces the probability of sovereign default by 5 percentage points in the following year. Given that the average default probability in the sample is 17%, this effect is highly significant.
📌 Financial Stability: Countries with a high IPR attract sustained capital inflows, enhancing their resilience against external shocks. An increase in the IPR is associated with a 4.4% rise in capital flows as a percentage of GDP.
📌 Faster Recovery: Nations with stronger political relationships experience smaller GDP contractions and recover credit access more quickly. Additionally, these ties reduce sovereign bond yields following a default, lowering borrowing costs.
The researchers employed advanced econometric techniques to ensure their conclusions were robust and applicable. They analyzed factors such as geographical proximity and shared languages to determine how these elements strengthen political ties and capital flows. They also separated long-term trends from temporary variations, ensuring the results reflect consistent patterns rather than short-term fluctuations.
This rigorous approach provides a clear and compelling picture of how international political relations influence economic stability, positioning diplomacy as a key tool for reducing financial risks.
Lessons for the Future
This study underscores the strategic importance of diplomacy and military cooperation in global financial stability. Countries with higher IPR scores tend to rely less on sovereign bonds in banking portfolios, reducing the risk of financial contagion. The findings encourage policymakers to strengthen international alliances as a mechanism for risk mitigation and economic resilience.
In an increasingly interconnected world, investing in international political relations could yield significant economic benefits.
At a time of global fragmentation, where political decisions have direct economic consequences, this study serves as an essential reference. By demonstrating that strong international political relationships are a key factor in economic stability, it calls on nations and organizations to invest in diplomacy as a crucial tool for preventing and overcoming sovereign debt crises.
