Executive Summary

Global public debt reached $111 trillion in 2025. Higher US yields and central bank balance sheet unwinding push borrowing costs up worldwide, and can weaken emerging market currencies. In developing economies, rising debt service crowds out public spending and squeezes liquidity.

Heavier government borrowing may leave corporate borrowers competing with sovereign issuers for investors. To cope with crowding-out and a tighter link between banks and their governments, multinational corporations may seek to reduce their operating subsidiaries' reliance on domestic banking systems, and some may extend more finance to local suppliers. Volatile public bond markets may also lead some companies to rely more on private credit.

In highly indebted emerging markets, debt service competes with public investment, including infrastructure. Sovereign debt conversions tied to environmental targets are one financing tool among several, which may open work for engineering and construction firms on climate projects. Corporate treasury departments may need better risk tools as debt markets become more volatile. Research on public debt management proposes using artificial intelligence for scenario analysis, and corporate issuers may in time adopt similar tools.

What matters

Key Findings

Global public debt reached $111 trillion in 2025, straining government budgets, especially in developing markets.

The global fiscal gap has shrunk to near zero, removing buffers for macroeconomic stabilisation.

Private creditors held 62 percent of developing countries' external public debt in 2021, up across all regions over the previous decade.

Category overview

PESTEL Summary

Each category is scored by the proportion of its forces rated high impact — 100 means every force in that category is high impact.

Political

4 forces

Geopolitical friction and multilateral frameworks dictate whether sovereign defaults are managed or chaotic.

Economic

16 forces

Macroeconomic conditions directly dictate sovereign and corporate solvency across global markets.

Social

1 force

Public resistance can constrain governments' ability to enact fiscal austerity. Citizens often protest when debt servicing demands tax rises or spending cuts.

Technological

2 forces

Technology determines the visibility of sovereign liabilities and the operational efficiency of public finance. Better data integration helps states manage complex debt profiles.

Environmental

3 forces

Climate transition costs impose massive new funding requirements on heavily indebted nations.

Regulatory

1 force

Financial regulations and monetary policy regimes define the structural cost of carrying debt. Historical low-rate regimes masked vulnerabilities.

Force Dynamics

Forces rarely act alone. Some chain into cycles that compound; others pull against each other and cap how far a move can run. Both are below, strongest-impact first.

What compounds

Cycles: the first force strengthens the second, the second the third, and the last feeds back into the first. Once running they carry their own momentum.

Rapid debt accumulation is a key risk to global financial stability

Economic

The increase in debt, especially in emerging markets, is a major source of risk to global financial stability and economic growth.

Calls for strengthening global and regional financial safety nets

Political

UNCTAD recommends strengthening global and regional financial safety nets to address structurally higher borrowing costs and improve debt sustainability.

Expanded multilateral lending facilities provide emergency liquidity to distressed sovereigns. This intervention prevents temporary illiquidity from spiralling into permanent defaults and structural financial crises.

Governments and financial institutions must manage sovereign exposure to prevent public debt distress from spilling over into banking crises.

Global Push for Unified Debt Data Integration

Better debt data helps markets judge which sovereigns can afford higher interest rates, which may help fiscally stronger nations borrow more cheaply despite global rate rises.

Scenarios

In the best-case scenario, rapid global economic growth combined with inflation helps erode the real value of debt, allowing developing countries to stabilize their debt-to-GDP ratios while keeping real interest payments manageable.

Escalating Global Public Debt Strains Developing Economies

In the worst-case scenario, rising interest rates push debt-servicing costs higher still, triggering a wave of sovereign defaults across vulnerable emerging economies and forcing severe domestic austerity.

Escalating Global Public Debt Strains Developing Economies

In the most-likely scenario, debt-to-GDP ratios remain flat, but governments continue to divert high percentages of domestic revenue to pay interest, resulting in slow public sector investment and stagnation in development indicators.
