Is the US in a debt-fueled national death spiral?

A recent analysis highlights concerns about the U.S. national debt, currently at $36.9 trillion, exceeding GDP and leading to a debt-to-GDP ratio of 123%. Treasury Secretary Scott Bessent's strategy of growing out of debt is questioned, with the World Bank projecting a downward revision of U.S. economic growth to 1.4% for 2025; furthermore, interest payments on the debt now surpass defense spending, raising concerns about America's future global power status given historical precedent.

Analysis

The U.S. national debt has reached $36.9 trillion, resulting in a debt-to-GDP ratio of 123%, a figure that has consistently exceeded 100% since 2013 and is projected to reach 140% by 2029. This situation challenges the notion, reportedly espoused by Treasury Secretary Scott Bessent, that the U.S. can grow its way out of debt, especially as the World Bank has revised its U.S. economic growth forecast for 2025 downwards to 1.4% from an initial 1.8%, following 2.8% growth in 2024. Historically, the U.S. successfully reduced a post-WWII debt-to-GDP ratio of 119% to as low as 31% by 1974 through sustained, high economic growth, a scenario deemed difficult to replicate given current challenges such as an aging population, global crises, and potential trade war impacts. Compounding these concerns, interest payments on the national debt have risen to $1.03 trillion, now exceeding the $907.7 billion defense budget. This development aligns with 'Ferguson's Law,' which posits that a great power risks decline when debt servicing costs surpass military spending, thereby potentially constraining resources for national security. The largest federal expenditures, Medicaid/Medicare at nearly $1.7 trillion and Social Security at $1.5 trillion, face inevitable and politically challenging cuts, while total federal revenue stands at $5.1 trillion, highlighting a significant fiscal imbalance.

Key Decisions for Investors

• Investors should closely monitor leading economic indicators, especially U.S. GDP growth relative to projections and debt accumulation rates, given the World Bank's downward revision of U.S. growth to 1.4% for 2025 and the projected 140% debt-to-GDP ratio by 2029.
• Consider the implications of rising debt service costs, which now exceed defense spending, for long-term interest rates, currency stability, and potential inflationary pressures.
• Evaluate portfolio allocations for resilience against potential fiscal tightening, including politically sensitive cuts to major entitlement programs or tax increases, and heightened geopolitical risks linked to constrained defense capabilities.
• Factor in the 'Ferguson's Law' thesis—that exceeding defense spending with debt service payments signals a potential decline in global power—when assessing long-term US sovereign risk and its impact on markets.
