As the world navigates the complexities of the post-pandemic era, debt has become a defining challenge for governments, businesses, and households alike.
In 2024, the international community witnessed a surge in borrowing unprecedented in modern history. Economists report that nearly $7 trillion was added to the global debt pile, pushing it to a historic $318 trillion record high by year-end.
This jump coincided with a slowdown in GDP growth and the easing of inflation, driving the debt-to-GDP ratio rose for the first time in four years. Both public and private sectors contributed to this expansion, reflecting the broad reliance on credit to sustain economies.
Meanwhile, government borrowing remains at elevated levels into 2025. The United States, France, China, India, and Brazil are leading in sovereign bond issuance, with OECD members expected to issue a record $17 trillion in bonds this year, up from $14 trillion in 2023.
These bonds have played a key role in funding recovery efforts since the 2008 financial crisis and the COVID-19 pandemic. As borrowing costs climb, however, there is growing pressure to redirect markets towards financing long-term investments that deliver sustainable growth.
Analyzing government debt relative to economic output offers critical insights into fiscal health. The following table highlights the 10 countries with the highest debt-to-GDP ratios in 2025.
Countries at the top of this list face unique historical and structural challenges. Sudan’s ratio reflects prolonged conflict, while Japan’s aging population contributes to persistent deficits.
High borrowing carries significant risks. Globally, public debt globally now totals about $100 trillion, and elevated interest rates have driven up servicing costs dramatically. In the United States, for the first time ever, interest payments have overtaken military spending, underscoring the scale of fiscal pressure.
Advanced economies are feeling the squeeze, with interest costs crowding out social programs, infrastructure investment, and climate initiatives. The United Kingdom, in particular, has been flagged for a potential “debt death spiral,” highlighting the thin line between manageable debt and unsustainable burdens.
Emerging and developing economies have continued to tap global markets, but they confront tighter conditions and rising yields. Countries like Lebanon, with an external debt-to-GDP ratio nearing 159%, face acute vulnerabilities to shifts in global sentiment.
Reliance on foreign lenders exposes these nations to exchange rate fluctuations and international policy shifts, making debt management a delicate exercise in balancing growth aspirations with financial stability.
These factors combine in a perfect storm, pushing nations towards greater reliance on borrowing as a tool to navigate immediate challenges.
The International Monetary Fund and other multilateral institutions remain key backstops. Through emergency liquidity lines and special drawing rights, they have cushioned economies in crisis and provided critical reserves for member countries.
Nonetheless, the global financial architecture faces calls for reform to address fragmentation and rising geopolitical tensions. Ensuring that institutions can respond swiftly to local crises while promoting sustainable borrowing will be vital for future stability.
High levels of debt have tangible effects on everyday lives. Austerity measures to rein in deficits often lead to cuts in healthcare, education, and essential public services, heightening social tensions and political instability in affected nations.
Compounding the challenge, financial literacy remains uneven. Many citizens and policymakers lack the tools to fully grasp the implications of complex borrowing structures, reducing accountability and hampering efforts to foster responsible fiscal behavior.
By adopting these strategies, governments can shift from reactive borrowing to proactive investment in long-term growth.
As of mid-2025, the world stands at a crossroads. The sheer size of global debt demands both vigilance and innovation. While the numbers can seem daunting, they also present an opportunity to rethink how borrowing can serve as a catalyst for sustainable development.
From reforming financial systems to investing in education and infrastructure, the choices made today will shape economic resilience for decades. With coordinated efforts, transparent policies, and informed citizens, nations can navigate their climate finance and sustainable development prospects and emerge stronger from their debt dilemmas.
