Frequently asked questions
Does the national debt matter for investors?
High and growing national debt is a long-term fiscal risk that can affect investors through: (1) higher interest rates -- as debt grows, Treasury must issue more bonds; all else equal, more supply raises yields; interest costs were $0.66 trillion in FY2023 (approximately 14% of federal outlays); (2) crowding out -- government borrowing competes with private borrowing; (3) potential future tax increases or spending cuts; (4) inflation risk if debt is monetized (Federal Reserve buying Treasuries). Historical evidence from other countries shows debt sustainability breaks down at different thresholds depending on currency status, growth rate, and interest costs. The U.S.'s unique position as global reserve currency provides significant buffer.
How does the deficit differ from the debt?
The deficit is the annual shortfall (spending minus revenue in one fiscal year). The debt is the cumulative total of all past deficits minus surpluses. The U.S. ran deficits in 47 of the 50 fiscal years from 1971 to 2024 (surpluses only in 1998-2001). Each year's deficit adds to total debt. Debt/GDP ratio is the standard measure of debt sustainability: U.S. debt/GDP exceeded 120% by 2024, up from approximately 35% in the early 1980s. Countries like Japan run debt/GDP of 250%+ without crisis; the key factors are currency sovereignty, domestic vs. foreign ownership of debt, and ability to grow out of debt.
How has Social Security contributed to the deficit?
Social Security is technically a separate 'off-budget' trust fund, funded by payroll taxes (FICA). For decades, Social Security ran surpluses (more payroll tax collected than benefits paid), which were used to purchase special Treasury bonds -- effectively loaned to the general fund. Social Security began running cash deficits around 2010 as baby boomers retired. The trust fund reserves (Treasury bonds) are being drawn down; the projected exhaustion date is approximately 2033, at which point revenues would only cover approximately 77% of promised benefits. Congress has not yet enacted solutions (raising payroll tax, raising retirement age, reducing benefits, or some combination).
