For decades, the mounting debt burdens of developing countries were often a “silent crisis” — a growing yet largely overlooked threat undermining economic stability and long-term development. Today, this silence has been shattered. The escalating costs of debt servicing, coupled with shrinking fiscal space and limited access to affordable financing, are pushing many nations into distress, threatening progress toward the Sustainable Development Goals (SDGs) and the well-being of billions.
In 2023, developing countries’ combined external sovereign debt reached $11.4 trillion, which is estimated at roughly 34% of their combined GDP. Annual debt service costs have soared to $1.7 trillion—a 110% increase from a decade ago, when annual service costs stood near $800 billion. This means many governments are spending more on debt interest than on vital sectors like healthcare, education, and social protection. Nearly two billion people live in countries where more public funds are allocated to interest payments than to social spending, while close to 38% of developing nations spend over 10% of government revenue servicing debt. For least developed countries, this figure is about 15%.
Against this urgent backdrop, the UN Secretary-General appointed an Expert Group on Debt in December 2024 to identify pragmatic, actionable solutions to break the cycle of debt distress and unlock sustainable financing pathways. Their comprehensive eleven-point agenda combine reforms of international institutions, regional cooperation, and national capacity building to restore fiscal stability, reduce borrowing costs, and channel affordable, long-term capital to developing nations.
The Escalating Debt Burden: A Looming Threat to Development
The debt burden facing developing countries has escalated dramatically, creating severe fiscal challenges that undermine development and sustainability. As noted earlier, debt servicing costs have soared in recent years. Nearly 38% of countries allocate over 10% of government revenues solely to interest payments; in least developed countries (LDCs), this figure approaches 15%. This generates severe fiscal crowding out — government budgets are forced to reduce critical social and infrastructure investments, posing severe risks to poverty reduction, healthcare, education, and climate adaptation efforts. Further compounding the crisis, in 2024, global official development assistance (ODA) flows declined by 7.1%—with forecasts of a further 20% drop in 2025—undermining a vital safety net for vulnerable economies. According to recent estimates, 3.4 billion people now live in countries where debt interest payments exceed social spending, a number increasing by 100 million in a single year.
Global economic headwinds compound these risks. The World Bank’s outlook estimates global growth of 2.3–2.8% in 2025, lower than prior projections, which will further dampen government revenues, especially in commodity-dependent economies. Declining commodity prices and shrinking foreign exchange earnings add pressure. Meanwhile, volatile capital flows and investor risk aversion, with frontier market bond yields spiking near 10%, make refinancing existing debt and raising new funds more expensive.
Structural Flaws
At the heart of worsening debt crises lie structural flaws in the global debt architecture. The creditor landscape has grown more complex and fragmented, with private creditors controlling 54% of external public debt in developing countries as of 2023, up from 40% a decade earlier. The rise of bondholders, commercial banks, and non-traditional bilateral lenders complicates coordination, prolonging and increasing the cost of restructurings.
The G20 Common Framework, designed to facilitate debt treatment, has been invoked by only four countries despite widespread distress, reflecting restrictive eligibility criteria and procedural inefficiency. Middle-income countries, many experiencing elevated distress, find themselves excluded from relief, despite growing liabilities.
Additional barriers include holdout creditors exploiting legal loopholes to seek full repayments through litigation and weak comparability of treatment clauses between creditors, which undermine collective action and prolong negotiations. Lending policies like the IMF’s “lending into arrears” rules delay disbursing critical funds during restructuring, intensifying liquidity shortages. These compounded shortcomings create a system that responds too slowly and unevenly, jeopardizing debtor countries’ fiscal resilience and recovery.
Reforming Multilateral Financial Institutions
To overcome these challenges, reforming and strengthening multilateral financial institutions is imperative. The UN Expert Group prioritizes repurposing and replenishing existing trust funds such as the Debt Reduction Trust Fund (DRTF) and the Catastrophe Containment Relief Trust (CCRT), extending their reach beyond low-income countries to middle-income and climate-vulnerable nations. Enhanced capitalization through donor contributions and innovative financing mechanisms (e.g., IMF gold sales, Special Drawing Right (SDR) allocations) would enable rapid deployment of liquidity to countries in crisis.
Embedded automatic debt service suspensions during shocks — pandemics, climate disasters — through instruments such as climate-resilient debt clauses (CRDCs)[1] that are innovative contract tools allowing for debt service suspension in the event of climate disasters, providing automatic fiscal relief to affected countries, which can provide immediate fiscal breathing space without lengthy renegotiations. CRDCs have proven effective in hurricane-prone Caribbean countries, limiting fiscal fallout.
The G20 Common Framework requires pivotal reforms: expanding eligibility to all distressed countries including middle-income economies, instituting automatic standstills on payments during restructuring, enabling parallel creditor negotiations, and strengthening collective action and comparability of treatment clauses to reduce holdout behaviors. Jurisdictional reforms, such as New York’s strengthened champerty laws[2], can protect sovereign borrowers against litigation-driven asset seizures by restricting third-party funding of litigation in exchange for a share of proceeds, to prevent the encouragement of frivolous lawsuits
Enhancing Debt Sustainability Analyses
Debt Sustainability Analyses (DSAs) conducted by the IMF are critical to assessing fiscal viability and guiding debt relief decisions. However, current frameworks often focus narrowly on near-term debt ratios and liquidity, failing to differentiate sovereign solvency from temporary liquidity shortages, and penalizing productive borrowing.
The Expert Group urges accelerated reform of DSA methodologies for both Low-Income Countries (LICs) and Market Access Countries (MACs)[3], which are nations that can regularly borrow from international markets, and thus face higher risks from volatile capital flows and interest rates, including integration of contingent liabilities, currency risks, and differentiation between growth-enhancing investments and consumption borrowing. This would encourage responsible borrowing aligned with the SDGs. Independent research advocates supplementary country-owned DSAs to provide transparency, ownership, and more dynamic risk assessments better tailored to diverse economies.
Leveraging SDRs to Scale Concessional Finance
SDRs, IMF’s reserve assets, have emerged as a largely untapped liquidity tool. The report highlights the slow and limited rechanneling of SDRs through the IMF Resilience and Sustainability Trust (RST) and multilateral development banks (MDBs), which hampers concessional financing capacity.
Legal complexities linked to SDRs’ reserve asset nature restrict their broad use. The Expert Group proposes pre-allocating new SDR issuances for MDB recapitalization before country allocations, potentially increasing MDB concessional lending capacity by up to fourfold. This would be critical to bridging the estimated $4 trillion annual SDG financing gap and supporting climate, pandemic recovery, and digital transitions in developing economies.
Promoting Regional Cooperation and Borrower Empowerment
No single actor can resolve the debt crisis alone; regional cooperation is key. The Expert Group advocates establishing a centralized information and technical assistance hub for innovative finance instruments such as debt-for-development swaps, blue bonds, and SDG-linked bonds, which face underutilization due to complexity and high transaction costs.
A Borrowers’ Forum would provide a unified platform to amplify debtors’ voices, facilitate South-South peer learning, and enhance negotiation power by sharing best practices and producing independent debt sustainability assessments. Such forums can balance creditor-dominated governance and improve transparency and policy outcomes
Strengthening National Debt and Fiscal Management Frameworks
At the country level, improving institutional capacity to manage liquidity, currency mismatches, and interest rate risks is foundational. Comprehensive, timely data on external, domestic, and contingent liabilities can empower negotiations, strengthen credibility, and improve fiscal planning. Developing high-quality, bankable investment project pipelines aligned with sustainable fiscal and development goals attracts better financing terms, mobilizes private investment, and reduces costs associated with debt swaps and innovative financing mechanisms. Standardizing issuance and aligning debt swaps with national strategies can build local markets, foster competition, and improve transparency and outcomes.
Navigating Political Realities: Prioritizing Pragmatic Reforms
Though large-scale debt cancellations encounter resistance amid fragmented creditors, achievable reforms focusing on extending maturities, normalizing automatic payment standstills, and improving debt transparency can yield tangible relief. The November 2025 World Bank Shareholders’ Meeting provides a crucial opportunity to advance capital adequacy frameworks that could unlock over $200 billion in concessional lending without new paid-in capital demands. Inclusive dialogues involving debtors and creditors must be at the heart of reform processes to realign incentives and ensure solutions are effective and fair.
Conclusion
The debt crisis is systemic, multi-dimensional, and intertwined with the broader challenge of financing sustainable development. As outlined in the eleven-point agenda, these multi-level reforms provide a realistic pathway to reduce debt distress, rebuild fiscal space, and mobilize affordable, long-term finance vital for the SDGs.
Success requires political will, coordinated global leadership, and inclusive governance reforms—enabling developing countries to break free from the debt morass, restore economic resilience, and achieve sustainable, inclusive growth.
1 CRDCs (Climate-Resilient Debt Clauses): Contractual provisions in sovereign debt agreements that automatically pause (or defer) debt repayments for a pre-determined period when a country is struck by a climate-related disaster or severe shock. For the debtor, this offers quick, temporary relief from payments, while for creditors, CRDCs provide certainty and mitigate risks compared to ex-post negotiations. CRDCs have recently been piloted in the Caribbean and with other vulnerable nations
2 Champerty law: An arrangement where a third party with no prior interest in a lawsuit finances or supports litigation in exchange for a share of the outcome. Laws regarding champerty are meant to prevent frivolous litigation and protect legal integrity. Some jurisdictions strictly prohibit such contracts as they allow outsiders to speculate on lawsuits and potentially impede settlement or promote unnecessary legal action
3 MAC (Market Access Countries): Countries classified by the IMF as having substantial and sustained access to international capital markets. These are generally nations capable of issuing external bonds or raising funds through non-concessional borrowing and are distinct from low-income countries that rely primarily on concessional finance. Debt sustainability frameworks for MACs are more complex compared to those for low-income countries, reflecting their exposure to market risks
