Across much of the Global South, a quiet external debt crisis has been unfolding for decades. It rarely makes U.S. headlines, yet its consequences impact U.S. interests.
Global South governments with vulnerable economies struggle to provide basic services and invest in major infrastructure projects, not because of a lack of ambition, but because of mounting debt burdens.
This is not only a financial issue, but a development challenge and a human rights concern. It also impacts the United States’ partnerships in the Global South and the stability of the international order. These themes were central to an April roundtable hosted by the Global South Policy Hub, which brought together Global South experts and U.S. congressional staffers to examine reforming the international financial architecture.
Debt Is No Longer Just an Economic Problem
For many countries, debt servicing has become one of the single largest constraints on development. Resources that could go toward building hospitals, improving roads, or expanding economic opportunity are instead directed toward repaying creditors.
According to Geneva Oliverie, a nonresident fellow at the Global South Policy Hub, governments in climate-vulnerable regions like the Caribbean face impossible trade-offs between maintaining infrastructure, supporting citizens, and meeting debt obligations. Rising energy and food prices, combined with climate shocks, push already fragile systems to the brink.
What emerges is a "debt crisis," as nonresident fellow Kamal Ramburuth put it, in which countries fall further behind, not because of domestic policy failures, but because of external shocks and structural constraints they did not create.
Broken By Design
Experts argue that the global financial system was not designed for the realities of countries in the Global South. Institutions such as the International Monetary Fund (IMF) and traditional creditor frameworks are widely considered too slow, too rigid, and poorly suited for addressing external debt challenges. Efforts to improve and expedite debt restructuring, such as the G20 Common Framework, have fallen short, with such processes delivering insufficient relief.
Private creditors now hold a large share of Global South debt, charge higher interest rates with shorter maturities, and operate largely outside traditional coordination mechanisms.
Not All Countries Are Equally Affected
The Global South is not a monolith, as some middle-income countries, such as Brazil, India, and South Africa, have access to a wider range of financial tools and buffers.
Many others, particularly small island states and climate-vulnerable countries, face far more acute constraints. These countries are often heavily dependent on imports and exposed to global price shocks. A single hurricane, spike in food prices, or war, such as the current U.S. war in Iran, can destabilize entire economies.
Without access to sufficient liquidity, these countries are left with few options and even less room for recovery.
The Rise of Alternatives and the Risk of Fragmentation
As traditional institutions struggle to adapt, alternative sources of financing are gaining ground. China’s role as a lender has expanded significantly, particularly in regions like the Caribbean and Latin America, offering faster, more flexible support without the burdening conditionalities attached to loans from Bretton Woods institutions. Despite China’s ability to bypass traditional bureaucratic mechanisms, it is not without its own conditionalities, such as its “unusual confidentiality clause,” as some experts note.
Regional development banks and new multilateral initiatives, such as the BRICS’ New Development Bank, are also stepping in to fill gaps. According to experts, governments are turning to these alternative partners to meet their immediate needs.
This shift carries broader implications. If traditional international financing institutions fail to evolve, the global financial system could continue to fragment. While alternatives provide short-term relief, a lack of transparency stemming from alternative practices could reduce coordination among creditors, borrowers, and multilateral institutions, thereby undermining long-term stability.
U.S. Leadership, Reform, and a Defining Moment
The United States remains a central player in the global financial system, but experts argue that its approach is at a crossroads. While previous administrations have made efforts to support vulnerable economies, these initiatives do not match the scale of the crisis. In 2021, for example, after previously opposing a new Special Drawing Rights (SDRs) allocation at the IMF, the Biden administration supported the IMF’s $650 billion allocation. However, despite the considerable benefits to the developing world and the United States alike, both the Biden and Trump administrations have failed to support new SDR issuances since then.
Without meaningful engagement on international financial reform, the United States will lose influence as Global South countries turn to alternative partners. A more effective approach would include supporting Global South-led proposals to strengthen regional development banks, ensuring private creditors' share in debt restructuring, and expanding liquidity access through additional SDR issuances. More ambitious mechanisms, such as automatic debt service suspension during crises, and proposals to establish a debt workout mechanism at the United Nations, among others, are already informing global financial reform.
These changes are central to shaping a more stable and equitable global financial system, enabling countries to invest in development, build resilience, and avoid recurring cycles of crisis.
The United States can either be leader in reforming a system under strain or prepare to be increasingly sidelined as its partners in the Global South seek alternative partnerships. The debt crisis in the Global South may not dominate U.S. headlines, but its consequences are already reshaping the global economy and the balance of influence within it.
