PART 1: OFFICIAL INFORMATION

On December 9, 2025, the Institute of International Finance (IIF) released its latest report showing that global debt has risen to a record level of approximately USD 345.7–346 trillion, marking the highest figure ever recorded in modern economic history. This number includes all government debt, corporate debt, household debt, and financial-sector debt worldwide. IIF stated that the global debt-to-GDP ratio is now around 310%, a threshold experts describe as “exceptionally high pressure” on the international financial system. This ratio indicates that global debt has far exceeded the economy’s ability to generate value, reflecting a significant imbalance in the financial structures of most economies.

According to the report, most of the increase in global debt comes from developed markets. This group of countries has raised its total debt to about USD 230.6 trillion, accounting for more than two-thirds of global debt. Among them, the United States and China were identified as the two largest contributors to the debt increase in 2025. Major economies such as the U.S., U.K., France, Germany, and Japan all recorded new debt accumulation, mainly driven by expanded public spending, prolonged fiscal deficits, and the continued issuance of government bonds to finance state operations. Meanwhile, emerging markets also saw a significant rise, with total debt exceeding USD 115 trillion, and the debt-to-GDP ratio of emerging economies reaching 242%, the highest level ever recorded for this group.

IIF emphasized that 2025 saw a much faster pace of debt accumulation compared to previous years. In this year alone, the world added roughly USD 26.4 trillion in new debt — equivalent to nearly USD 675 billion per week. The primary causes stem from monetary policy easing in many major economies, a low-interest-rate environment during most of the early part of the year, and a weakening U.S. dollar, which increased the value of foreign-currency debt when converted into USD. This has created strong pressure on countries borrowing in USD but earning fiscal revenue in local currencies, particularly emerging markets.

In the structure of global debt, IIF reported that government debt is the largest contributor to the record surge. Many countries expanded public spending to support post-pandemic recovery and to finance social programs, security, healthcare, technology, and energy. High fiscal deficits forced governments to issue additional bonds, increasing the burden of public debt. In addition, corporate debt also rose significantly as firms took advantage of low interest rates to restructure capital, expand production, or invest in new sectors. Household debt in many developed countries continued to rise, mainly due to increased borrowing for housing, consumer credit, and escalating living costs.

A notable point in the report is that debt in emerging markets has increased not only in scale but also in risk level. These economies are facing substantial refinancing pressure, as a large portion of short-term debt will mature during 2026–2027, while international borrowing costs are expected to rise again if central banks increase interest rates to control inflation. In this volatile global financial environment, the likelihood that emerging economies may face liquidity stress or need to restructure debt is a concern experts have repeatedly warned about.

Another factor heightened global debt risk is the slowdown in global economic growth, while debt accumulation continues to accelerate. When GDP growth cannot keep pace with debt accumulation, the debt-to-GDP ratio rises and weakens the economy’s repayment capacity. The fact that debt is increasing faster than economic output shows that debt efficiency is declining, meaning each new dollar of debt generates less value than before. This is a clear warning sign of an imbalance between public finance, corporate finance, and the real growth capacity of the global economy.

In addition, the report points out that geopolitical tensions and global supply chain disruptions in 2025 have led many countries to sharply increase investments in defense, technology, and strategic sectors — all of which contributed to higher national debt. At the same time, companies in technology, infrastructure, energy, and transportation borrowed more to sustain operations in an increasingly competitive global landscape.

IIF warned that the current massive level of global debt makes the international financial system extremely sensitive to changes in interest rates, exchange rates, and capital flows. Even a small shock from major markets such as the United States, China, or Europe could quickly spill over to other economies through the banking system, bond markets, and international credit channels. The risk of sovereign debt crises or localized defaults in certain countries could trigger contagion effects, causing widespread economic and financial instability.

The overall picture presented by the IIF report is a strong warning: the world is facing an unprecedented mountain of debt, while the global economy is not generating enough growth to absorb it. The combination of rising public debt, persistent fiscal deficits, expanding corporate debt, and increasing household debt makes policymaking, economic recovery, and financial stability far more challenging than ever before.

This week’s global debt report shows that the world is confronting one of the largest financial challenges in decades: global debt reaching USD 346 trillion, a 310% debt-to-GDP ratio, combined with intense refinancing pressure, liquidity risk, and high sensitivity to macroeconomic volatility. This is not merely a statistical figure but a systemic warning that the world may be approaching a major financial adjustment cycle unless sustainable policies and effective debt-management measures are implemented in the near future.
