‘We are guilty of spending our rainy-day fund in sunny weather’: Top economists, historians unite to urge action on $38 trillion national debt

Experts warn that the U.S. national debt, at $38 trillion and over 120% of GDP, constitutes a critical "dangerous fiscal gamble," with annual servicing costs now exceeding defense spending. This structural issue, characterized by projected permanent deficits and the inapplicability of historical solutions, threatens U.S. economic strength, dollar dominance, and global leadership by crowding out productive investment and risking bond market instability. Political polarization further exacerbates the slow-motion crisis, suggesting that increased revenue is the most viable path to avert severe economic consequences stemming from eroding institutional integrity.

Analysis

The U.S. national debt, currently $38 trillion and over 120% of GDP, is deemed a "dangerous fiscal gamble" by experts. Annual debt servicing costs now exceed defense spending at approximately $1 trillion, indicating a critical structural issue. Economists project "big permanent deficits" around 6% of GDP in the 2020s, a significant departure from historical norms despite low unemployment.

Past debt reduction methods, such as post-WWII growth or 1990s defense cuts, are unavailable today due to unfavorable conditions. Political polarization and protected entitlement programs exacerbate fiscal gridlock, making increased revenue the most viable solution. This debt crowds out productive spending in defense, cybersecurity, and public health, posing a direct threat to national security.

The escalating debt threatens U.S. dollar dominance and the international monetary system, creating a "specter of political risk in U.S. sovereign bond markets." Erosion of institutional integrity and potential political interference undermine the "exorbitant privilege" of the dollar. This loss of credibility could empower bond markets, leading to sudden economic consequences like surging interest rates and instability.

Key Decisions for Investors

• Monitor U.S. fiscal policy developments closely, particularly any proposed revenue-raising measures or attempts at fiscal consolidation, as political gridlock remains a significant impediment.
• Assess the potential for increased interest rate volatility and its impact on fixed-income portfolios, given the rising debt servicing costs and the risk of bond market displeasure.
• Evaluate the long-term implications for dollar-denominated assets and the dollar's global reserve status, considering the erosion of institutional integrity and the "dangerous experiment" with the currency.
