A Growing Debt Crisis in the Global South

Across much of the developing world, government debt has reached levels that are crowding out spending on schools, hospitals, infrastructure, and climate adaptation. In some countries, debt service payments now consume a larger share of government revenue than health and education combined. The causes are complex, the consequences are severe, and the path to resolution is deeply contested.

How Countries Get Here

Sovereign debt crises rarely have a single cause. They typically involve a combination of:

  • Commodity dependence: Many lower-income countries rely heavily on commodity exports. When prices fall, revenues collapse but debt obligations remain fixed.
  • Dollar-denominated borrowing: Much external debt is priced in US dollars. When the dollar strengthens — as it did significantly in 2022 — the local-currency cost of repayment rises sharply, even if nothing else changes.
  • Higher global interest rates: As advanced-economy central banks raised rates to fight inflation, the cost of borrowing on international markets increased dramatically for emerging economies.
  • Accumulated borrowing from multiple creditors: Over the past two decades, the creditor landscape shifted significantly. Many countries borrowed from Chinese state banks, private bondholders, and multilateral institutions simultaneously, creating complex multi-creditor situations that are difficult to restructure.

The Restructuring Problem

When countries can no longer service their debts, they typically need some form of restructuring — extending repayment timelines, reducing interest rates, or writing down the principal owed. But the modern debt architecture makes this far harder than it was in the 1980s or 1990s.

There is no international bankruptcy court for nations. The G20's Common Framework — established to coordinate debt treatment — has been widely criticised for moving too slowly and failing to include private creditors meaningfully. Countries that need relief have often waited years for processes to reach agreement, a delay that extends the economic pain for their populations.

The Human Cost

Debt distress is not an abstract financial problem. When governments spend heavily on debt service, they cut spending elsewhere. The consequences tend to fall hardest on the most vulnerable: reduced healthcare access, underfunded schools, fewer public jobs, and delayed investment in infrastructure and climate resilience at precisely the moment it is most needed.

What Reform Advocates Are Calling For

A broad coalition of economists, civil society organisations, and some governments has been pushing for more fundamental changes to the international debt architecture:

  1. A faster, more inclusive mechanism for sovereign debt restructuring that binds all creditor types
  2. Climate-linked debt swaps — converting debt obligations into investments in climate adaptation
  3. Greater access to concessional (low-interest) multilateral financing for climate-vulnerable nations
  4. Reform of IMF special drawing rights allocation to direct more liquidity to lower-income countries

The Political Dimension

Progress on debt reform is slow partly because it requires creditor nations — including major powers with geopolitical interests in their lending relationships — to accept real costs. The competition between Western-led institutions and China's bilateral lending programmes adds a further layer of complexity. For the countries caught in between, waiting for great-power consensus is a luxury that human welfare cannot afford.
