National Debt's $39T Toll: Higher Rates, Social Security Cuts Loom

Conference Board report warns advisors that rising federal debt could lift borrowing costs, trim retirement benefits, and squeeze small businesses.

The United States national debt has crossed $39 trillion, translating to roughly $116,000 per citizen, and a fresh analysis from the Conference Board suggests financial advisors should brace clients for tangible fallout. The report, produced with The CEO Center, maps how the federal fiscal path is already lifting borrowing costs, threatening retirement income, and straining household budgets across four critical areas: college financing, homeownership, Social Security, and small business expansion.

“Higher debt can mean higher borrowing costs for families and businesses, fewer resources for national priorities, and greater uncertainty about programs Americans depend on in retirement,” said David K. Young, president of The CEO Center, in a statement accompanying the research.

Debt trajectory and market signals

Under the Conference Board’s baseline scenario—which assumes annual deficits of 6–7% of GDP—the national debt is projected to reach 154% of GDP by 2036. In a higher-deficit scenario, that figure climbs to 180%. The government now spends more on debt interest annually than on national defense, according to the report.

These projections carry direct implications for clients. Ten-year Treasury yields are expected to average around 4.1% by 2036 under the baseline, rising to 4.6% in the adverse case. A modeled one-week government default in 2029 could spike rates to 6.9% before settling near 5.6% over the longer term. The bond market is already reflecting the strain: the 10-year Treasury yield stood at 4.6723% on Thursday morning, while the 30-year reached 5.2256%—levels not seen since before the 2008 financial crisis, according to CNBC.

Yields had pulled back sharply the prior session after Treasury Secretary Scott Bessent announced the department would double its debt repurchase operations, focusing on the long end of the curve. That intervention sent the 30-year yield down more than 10 basis points in a single day. The move came as total government debt crossed $40 trillion, underscoring the volatility now embedded in the rate environment.

Impact on homebuyers and borrowers

For a family purchasing a $600,000 home, the fiscal outcome matters significantly. Under a better-case scenario—where the deficit is trimmed to roughly 3% of GDP—housing costs could fall by 1.8%, saving about $53,000. In the bad-case scenario, the same purchase could cost around $55,000 more. For clients planning to buy in ten years rather than five, those swings widen to 3.7% in either direction.

Student debt compounds the picture. Americans currently owe $1.87 trillion in student loans, with 10.3% of loans 90 or more days delinquent as of the first quarter of 2026, up from 7.7% a year earlier. In an extreme interest rate shock—where rates double—student loan payments could rise by as much as 61%, adding roughly $310,000 to total repayments over a borrower’s lifetime.

Social Security: a 2032 deadline

Perhaps the most urgent finding for advisors is the Social Security timeline. The primary Trust Fund is projected to become insolvent in 2032, based on Congressional Budget Office projections cited in the report. If Congress takes no action, a retiree currently receiving $2,100 per month could see benefits cut by $173 monthly beginning in 2032, with losses exceeding $700 annually thereafter.

Restoring full solvency through Trust Fund backfilling alone would require $2.7 trillion between 2032 and 2036, further widening deficits unless offset by new revenue or spending cuts. The Conference Board recommends a combination approach: gradually raising the full retirement age to 69, adjusting cost-of-living formulas, implementing modest means testing for high-income beneficiaries, and raising or eliminating the cap on income subject to payroll taxes.

Small business clients face outsized risk

The report’s findings for small business owners are also concerning. Two business loans totaling $250,000 would cost approximately $105,000 more in total payments under the bad-case fiscal scenario, a 7% increase. Under an extreme interest rate shock, that figure balloons to more than $1 million in additional costs, representing a 67% increase over baseline projections.

Context adds to the concern: small business profitability fell 1.3% year-over-year as of April 2026, while gasoline spending among small businesses rose 31% over the same period—a sign that cost pressures are already biting before any further rate-driven deterioration.

Policy path forward

The Conference Board calls on Congress to establish a bipartisan fiscal commission empowered to stabilize the debt-to-GDP ratio at a sustainable level—the report suggests 100% as a target—and to develop reform plans for Social Security and Medicare that are subject to floor votes. Additional recommendations include extending Congressional Budget Office projections from 10 to 25 years and establishing statutory targets for reducing debt to 70% of GDP over the longer term.

The report stops short of advocating any single political approach, but its message is clear: the longer fiscal decisions are deferred, the more constrained the range of outcomes for American families, businesses, and retirees will become. For advisors, the takeaway is to incorporate these scenarios into client planning, particularly for those nearing retirement or considering major purchases. As recent surveys show, many Americans lack concrete plans for Social Security changes, and retirement confidence varies widely across demographics. Advisors can help by stress-testing portfolios against higher rate environments and continuously monitoring estate plans to adapt to fiscal shifts.
