There are figures that don’t quite add up somewhere in the ledgers of a ministry of finance in Accra, Colombo, or Lusaka. They haven’t in a long time. The cost of debt servicing has increased to the point where basic infrastructure spending is no longer competitive. Budget lines used to support hospitals are being eaten by interest payments. Additionally, the investors who used to queue up to purchase bonds from these nations are becoming more reserved and cautious, exchanging anxious looks across trading floors from Singapore to London.
This is how a sovereign debt crisis feels in its early stages. Seldom does it make a loud announcement. Spreadsheets, rising bond spreads, and a finance minister’s well-crafted press conference that manages to say very little are all examples of how it manifests.

The early 2010s euro-area debt crisis demonstrated to the world what contagion looks like when it spreads quickly. The foundations of a currency union that was meant to be unbreakable were shaken by stress that started in Greece, a nation that accounts for a small portion of the European GDP, and spread to Ireland, Portugal, Spain, and Italy. When investors who made simultaneous loans to several nations began to absorb losses in one location, they pulled back across the board. The mechanism was almost elegant in its cruelty. Spain’s credit squeeze was caused by Greece’s wounds. Shared investor pools are like that. The entire ship lists with just one leak.
The next wave of sovereign defaults might resemble this one quite a bit, with the exception that the participating nations won’t have a European Central Bank supporting them with a bazooka. The situation in the developing world is completely different.
Since the pandemic, government debt has risen to all-time highs in both emerging markets and lower-income economies due to crisis spending, commodity shocks, and the hopeful belief that global interest rates would remain low indefinitely. They didn’t.
The connection is what makes this moment truly unsettling, and this isn’t alarmism; it’s just math. When two borrowing countries share the same pool of foreign investors, what occurs in one country directly impacts the borrowing conditions of the other, according to research by economists studying two-country sovereign default models. Even if a second country has done nothing wrong by any standard measure, a default in one part of the developing world can severely restrict credit in another. Instead of any obvious political or economic connection between the countries themselves, the contagion spreads through investor balance sheets.
For years, there has been a discussion about what to do about this, but it has never been fully settled. Some economists advocate for formal cross-national agreements, such as coordinated borrowing regulations, structured bailout mechanisms, or something akin to a central borrowing authority that takes into account how one country’s debt decisions affect its neighbors. The attraction is genuine. According to research, a central borrower that internalizes these cross-country effects would improve collective welfare by issuing less debt overall and defaulting less frequently. There is a belief that rational coordination ought to be possible.
However, there is a political catch. Gains are never distributed equally, even when joint welfare increases under a coordinated arrangement. According to the models that researchers have developed, one nation benefits while another suffers. In order to stabilize the economy of another country, no government will sign an international borrowing agreement that makes its own citizens poorer. The math is universal. Domestically, it fails. And this is precisely where these arrangements tend to fail—between national politics and global rationality.
Perhaps the more obstinate of the two is the moral hazard issue. When bailouts are anticipated—that is, when governments have good reason to think that a rescue will occur if things get bad enough—they often promote the exact behavior that they are intended to stop. When the time of reckoning finally comes, anticipated bailouts are linked to higher debt levels, more frequent defaults, and larger bailout packages. The incentives are altered by the expectation. It’s a safety net disguised as a feedback loop.
And yet. It appears that unexpected bailouts, or truly unexpected interventions, improve welfare and lower default rates. The irony is nearly excruciating. A bailout is most effective when no one anticipates it and least effective when everyone has taken it into account when planning their borrowing.
There’s a sense that the world doesn’t have a good solution as we watch all of this unfold in real time across twelve nations that are silently battling debt loads they can no longer handle. The World Bank, the IMF, and regional development banks are examples of institutional architecture designed for a different time period and problem scale. Whether these bodies can move quickly enough or in unison enough to stop the next wave of defaults from growing into something more significant and challenging to contain is still up for debate. The road is running out for the developing world. Additionally, the investors who funded the trip are keeping a close eye on the fuel gauge.
