The Looming Debt Crisis: An Irreparable Economic Threat

Budget Chair Jodey Arrington has characterized a potential debt crisis as a threat that is equal to or greater than national security demands.

Speaking on the balance between fiscal stability and national security, Arrington described himself as a debt hawk and stated, I can tell you there are debt hawks like myself that see a debt crisis on the horizon as an equal if not greater and more irreparable threat.

The warning comes amid broader concerns regarding the sustainability of national and global borrowing. A July 15, 2024, analysis indicates that a debt spiral within the United States could potentially destabilize the global economy.

Global Debt Trends and Risks

The concerns raised by U.S. Fiscal leadership align with data from the World Bank. Chief Economist Indermit Gill reported on June 9, 2025, that total global debt is now nearly 25 percent higher than it was before the COVID-19 pandemic, a period when debt had already reached an all-time high.

Gill noted that this debt overhang may reduce the ability of economies to protect themselves against new economic shocks, such as increased trade tariffs.

The World Bank identifies debt as a form of deferred taxation. While borrowing allows governments to make long-term investments or support growth during emergencies without immediate tax hikes, the cost of borrowing must be lower than national income growth to avoid the necessity of future tax increases to repay the debt.

Impact on Developing Economies

Developing nations have experienced a particularly aggressive increase in borrowing. Over the last 15 years, these countries amassed debt at an average rate of six percentage points of gross domestic product (GDP) per year.

The World Bank reports that such rapid debt accumulation carries a risk of triggering a financial crisis, estimating the odds at roughly 50-50.

This surge in borrowing has coincided with the fastest increase in interest rates seen in four decades. According to World Bank data, borrowing costs doubled for half of all developing economies.

The financial pressure is evident in government spending allocations. Net interest costs as a share of government revenues for these nations rose from less than 9 percent in 2007 to approximately 20 percent in 2024.

World Bank analysis suggests that the combination of high borrowing costs and weak growth could lead to lasting economic setbacks for developing countries without urgent reforms.
