IMF Warns Global Public Debt Could Climb Back to Pandemic Peaks

The International Monetary Fund (IMF) projects that global public debt will soon exceed the peaks reached during the COVID-19 pandemic, edging toward 100% of global GDP by 2030. After rising to 98.9% of global GDP in 2020 and then falling by roughly ten percentage points over the following two years, public debt is now rising again at a worrying pace. These projections highlight renewed fiscal pressures for governments worldwide and raise questions about future economic stability and policy choices.

Key Drivers of Rising Debt

The IMF points to a mix of factors that are contributing to the renewed climb in public debt. Among them are trade policy shifts—specifically recent tariff announcements from the United States and the risk of retaliatory measures from trading partners—which have increased uncertainty for global trade and investment. This kind of uncertainty can slow economic growth, reduce government revenue, and increase the need for fiscal support, all of which push up debt levels.

Another contributing factor is the persistence of elevated fiscal deficits. The IMF forecasts global fiscal deficits of about 5.1% of GDP in 2025, slightly higher than the projected 5.0% in 2024. While the change may appear modest, sustained deficits at these levels make it harder to stabilize or reduce debt over time, particularly if economic growth underperforms or if interest costs rise.

Concentration of the Problem in Major Economies

Although fewer than half of IMF member countries are experiencing faster debt growth than before the pandemic, those that are account for about 80% of global GDP. This concentration means the most significant fiscal pressures are in large, systemically important economies. When major economies face rising public debt, the implications become global: higher borrowing costs, reduced fiscal space to respond to crises, and potentially weaker global demand.

The IMF also highlights a downside scenario tied to trade policy escalation. If steeper tariffs are implemented and spur broad international retaliation, debt ratios could increase sharply. Under such a scenario, global public debt might surpass 117% of GDP by 2027, reaching the highest levels since World War II. While this is a conditional projection rather than a forecast, it underscores how quickly policy shifts and trade disputes can magnify fiscal vulnerabilities.

Economic and Social Implications

Rising public debt at global scale carries several implications. First, governments may face tougher choices between maintaining public services and paying higher interest costs on debt. Persistent deficits can limit the ability to invest in infrastructure, health, education, and climate resilience—areas that are critical for long-term growth and social welfare.

Second, elevated debt levels can constrain monetary and fiscal policy coordination. Central banks may be pressured to keep interest rates lower to reduce governments’ borrowing costs, which can limit central banks’ ability to combat inflation. At the same time, governments with high debt may lack the fiscal room to respond effectively to recessions or to new shocks.

Policy Responses and Priorities

Addressing rising public debt requires a balanced policy approach. Short-term support should remain targeted to protect vulnerable households and sectors while avoiding large, open-ended spending commitments that are hard to unwind. Medium-term strategies should prioritize policies that boost sustainable growth and improve the composition of public spending—shifting toward investments with high returns and away from less productive outlays.

Fiscal consolidation, where appropriate, will need to be gradual and growth-friendly. Measures to broaden the tax base, improve tax administration, and reduce wasteful spending can help lower deficits without unduly harming economic activity. At the same time, multilateral cooperation to prevent trade escalations and to maintain open markets can reduce the risk of shock scenarios that would worsen debt trajectories.

Looking Ahead

The IMF’s projections serve as a reminder that public debt dynamics remain fragile and subject to abrupt changes in policy and economic conditions. Policymakers in large economies face particular responsibility: their choices on trade, fiscal policy, and growth-oriented reforms will shape not only domestic outcomes but also global financial stability. Close monitoring, transparent communication, and coordinated action where possible can help manage risks and preserve fiscal space for future challenges.
