The National Debt Will Grow to Be Twice the Size of the Economy

The Congressional Budget Office (CBO) recently released projections showing that the national debt will nearly double in size in the coming decades. If current laws remain the same, debt held by the public would rise from 102 percent of gross domestic product (GDP) at the end of 2021 to 202 percent at the end of 2051. The debt growing to double the size of GDP is, in many respects, a symbolic milestone — but it is a clear indicator of the monumentally unsustainable path of our fiscal trajectory.

The national debt is on an unsustainable path


The agency’s baseline projections earlier this month indicated that while the COVID-19 pandemic has exacerbated the nation’s fiscal trajectory, the structural mismatch between spending and revenues will be the primary driver behind the nation’s growing debt long after the pandemic is behind us. Over the 10-year period from 2022–2031, the federal deficit is expected to average 4.4 percent of GDP. That budgetary shortfall would leap to an annual average of 11.5 percent of GDP over the 2042 to 2051 period. As was the case before the pandemic, predictable factors such as rising healthcare costs and an aging population — along with insufficient revenues to meet our commitments — would fuel such growth in the nation’s debt and deficits. The interest costs paid on that mounting debt would also grow rapidly; CBO projects that interest costs would average 7.0 percent of GDP between 2042 and 2051 — 3.5 times larger than the average of 2.0 percent over the past 50 years.

Federal deficits will continue to grow over the next several years


A sustainable fiscal trajectory is essential for a strong economy. While the economic damage from the COVID-19 pandemic and the necessary legislative response have led to an unprecedented rise in federal borrowing, the underlying gap between spending and revenues threatens the nation’s fiscal future in the decades ahead. Once the pandemic has subsided and the nation’s economy has fully recovered, policymakers should return to addressing America’s fiscal challenges.
