We are living in a time when many countries face heightened debt vulnerabilities. Already high before the pandemic, debt levels reached a 50-year peak following the growth in government spending to combat COVID-19. Debt is not inherently bad; borrowing can allow countries to finance vital government investment. But unsustainable levels of debt can have devastating consequences for a country’s population, crowding out government spending on even basic necessities including food, medicine, and fuel imports. In Sri Lanka, for example, 71 percent of government revenue was spent on debt service before the country defaulted. Even where the tradeoff is not so dire, unsustainable debt service can limit productive investments in infrastructure, education, healthcare, and other sectors, hampering the economic growth necessary to reduce a country’s debt burden.
