Global debt surged to an unprecedented **$337.7 trillion** at the end of the second quarter, delivering a sharp warning from financial analysts that the world economy may be entering a new phase of risk. According to the Institute of International Finance (IIF), loosening financial conditions, a weaker U.S. dollar, and more accommodating monetary policy across many major economies are behind the climb. While growth in debt itself isn’t new, its scale, shifting composition, and looming repayment pressures are raising concerns about global economic stability.

Drivers Behind the Surge in Global Debt

A combination of macroeconomic factors has powered the recent jump in global debt. First, central banks in many regions have moved toward more accommodative policies, lowering borrowing costs and enabling governments, corporations, and households to take on additional debt. Meanwhile, financial markets have eased, making capital more available.

Second, the U.S. dollar has weakened significantly against a basket of major currencies. A softer dollar means that debts denominated in foreign currencies become less expensive in dollar terms when converted, which inflates debt values of non-U.S. borrowers when reported in dollars. This currency effect boosted the debt totals of several major economies, especially those with large external financing obligations.

Third, many countries and sectors borrowed heavily to manage inflation, energy transitions, climate adaptation, and infrastructure demands. Governments increased fiscal spending, companies took on new liabilities, and households continued borrowing in an environment of low interest rates—until recently. Emerging markets in particular saw sharp increases, both from economic activity and from needing financing for growth, resiliency, and catching up with infrastructure gaps.

What Nearly $338 Trillion Means for the Global Economy

The sheer magnitude of debt raises several red flags for economic stability. Debt servicing costs are rising as interest rates climb worldwide; governments and companies with large debt burdens may find their financial flexibility restricted, particularly if refinancing must be done under less favorable conditions. That can lead to tighter budgets, reduced investment, and slower growth.

High debt levels can also make economies more vulnerable to external shocks—such as fiscal crises, financial market turbulence, or changes in global trade or commodity prices. If investors lose confidence, sovereign bond yields may jump, increasing costs for borrowing. Countries with weaker credit profiles could see refinancing risk become a serious issue.

For households and corporations, excessive leverage increases financial fragility. Rising interest rates mean more expensive servicing of debt. In many places, high levels of private debt amplify risk: borrowers may cut back on spending, mobility, or investment in face of higher payments, dragging aggregate demand. Governments may be forced to implement austerity, raise taxes, or limit spending—actions that can stifle growth or social welfare.

In emerging markets, the concern is magnified. Many have raised large amounts of debt, both domestic and external, often with shorter maturities or in foreign currencies. They face a record $3.2 trillion in bond and loan repayments coming due before the end of 2025—an enormous refinancing challenge. For some, debt-to-GDP ratios and fiscal deficits are rising fast, putting pressure on policy makers to balance growth objectives with financial sustainability.

Top Five Countries Leading the Debt Buildup

Some nations have contributed disproportionately to the recent global debt expansion. Among them:

• United States remains one of the largest issuers of debt. Its debt levels have increased notably, in part due to fiscal stimulus, rising government spending, and more short-term borrowing.
• China also recorded a major rise, driven by government borrowing, infrastructure investment, and corporate and local government debt accumulation.
• France and Germany both saw large upticks in debt expressed in U.S. dollar terms, in part because of currency movements and also because of increased government expenditure and borrowing.
• Britain and Japan also stand among the top countries with large increases, both public and private, largely reflecting government fiscal needs, stimulus, social spending, and exposure to foreign borrowing or import costs.

Together, these countries account for much of the increase in global debt. In addition to sheer size, each faces specific pressures—aging populations, expensive public services, green transition costs, energy imports, or fiscal stimulus commitments.

Debt-to-GDP Ratios and Emerging Markets Under Stress

A vital measure of sustainability is the debt-to-Gross Domestic Product (GDP) ratio, which shows how much debt exists compared to what an economy produces. Globally, that ratio has held just above **324 percent**, meaning the world owes more than three times the total annual output. In emerging markets, the ratio rose to about **242.4 percent**, setting a new record.

Certain countries are seeing particularly sharp climbs in their debt burden relative to GDP—most notably **Canada**, **China**, **Saudi Arabia**, and **Poland**. These increases reflect new borrowing, but also slower growth in some cases and shifts in currency values.

Conversely, some economies saw their debt ratios fall. **Japan**, **Ireland**, and **Norway** reported declines, driven either by stronger growth or favorable exchange rate effects, and in some cases constrained new borrowing.

Risks Ahead from Debt Maturity, Bonds, and Market Sentiment

One looming risk is bond and loan maturities. Emerging markets alone have nearly **$3.2 trillion** in redemptions due in the remainder of 2025. Without smooth refinancing, a spike in borrowing costs or tightened conditions could lead to stress for companies and governments. Timing matters: if interest rates or investor risk perception shift suddenly, refinancing may become very costly or constrained.

Another risk is short-term borrowing, especially in advanced economies. E.g., a large portion of U.S. government debt now is issued in short-term instruments. While cheaper initially, it carries rollover risk: when interest rates rise or market sentiment turns, refinancing short-term debt becomes more expensive and volatile. This could constrain policymaker flexibility and place upward pressure on spending costs.

Investor behavior, especially in bond markets, is sensitive to perceptions of sustainability. If investors judge that debt levels are too high or growth prospects weak, they may demand higher yields or withdraw. For countries heavily exposed, especially those with weak fiscal positions, this could lead to rising borrowing costs or double-digit yield spreads, putting pressure on finances.

Policy Implications and What to Watch

Governments and central banks will need to pay attention to both quantity and quality of debt. Not all debt is equal: debt incurred for productive investment—in infrastructure, green transition, health systems—can improve future capacity and growth. Debt used merely for consumption or to patch deficits has less return and poses more risk.

Monetary and fiscal coordination becomes critical. As rates rise globally, fiscal discipline may need strengthening to avoid destabilizing budget deficits. But austerity may hurt growth if applied too aggressively. Many countries will need to strike balance: tightening budgets gradually, protecting essential public investment, and maintaining social safety nets.

Structural reforms also matter: broadening tax bases, improving tax collection, cutting waste, reforming public services, and targeting subsidies effectively. These help reduce the need to borrow and improve debt serviceability.

Attention should also come to exposure to foreign currency debt and short maturities. Countries with a lot of debt in foreign currencies are especially vulnerable to currency swings and tightening global financial conditions.

Finally, global coordination may be necessary. Debt excesses in one region or major economy can have spillovers—through interest rates, through global financial flows, and through trade. Monitoring agencies, multilateral institutions, bond markets, and credit rating bodies will play major roles in assessing risk and pushing policy responses.
