Trump's 'big beautiful' bill could add $3.4 trillion to federal deficits in the next 10 years—what it means for your wallet

The Congressional Budget Office projects the recently signed U.S. tax-and-spending bill will increase federal deficits by $3.4 trillion over the next decade, pushing gross federal debt past $36 trillion and public debt to nearly 118.5% of GDP by 2035. This trajectory, with interest payments already consuming over 13% of federal spending, raises significant concerns about higher interest costs, slower economic growth, reduced budgetary flexibility, and potential inflation. Despite these warnings, the bond market currently remains relatively calm, reflecting continued global confidence in U.S. Treasuries; however, this stability is contingent, and a loss of investor trust could rapidly escalate borrowing costs.

Analysis

The U.S. fiscal outlook is deteriorating significantly, with a new tax-and-spending bill projected by the Congressional Budget Office (CBO) to add $3.4 trillion to deficits over the next decade. This exacerbates an already strained fiscal position, characterized by a gross federal debt exceeding $36 trillion—a more than 50% increase since early 2020. The CBO forecasts that debt held by the public, currently above 90% of GDP, will reach an unprecedented 118.5% of GDP by 2035. A critical consequence is the escalating cost of debt service, which already consumes over 13% of federal spending and is projected to rise to 16.7% by 2035, thereby constraining budgetary flexibility for other priorities and economic shocks. Despite these stark long-term warnings of slower growth and inflationary pressure, the U.S. bond market remains anchored, reflecting continued global confidence in Treasuries as a safe-haven asset. The 10-year Treasury yield is holding near 4.4%, and a recent auction drew strong demand. This creates a significant disconnect between deteriorating fiscal fundamentals and current market placidity, underscoring a latent tail risk of a sudden, sharp repricing of U.S. sovereign debt should that investor confidence falter.

Key Decisions for Investors

• Investors should review fixed-income portfolios for duration risk, as the structural deficit implies long-term upward pressure on yields which could be catalyzed by a shift in market sentiment.
• Monitor leading indicators such as Treasury auction bid-to-cover ratios and foreign demand for U.S. debt for early signals of eroding investor confidence.
• Consider overweighting equities of companies with strong balance sheets, high free cash flow generation, and significant pricing power, as they are better insulated from rising borrowing costs and potential inflation.
• Given the risk of reduced budgetary flexibility for fiscal stimulus, evaluate portfolio exposure to economic downturns and the potential for a slower long-term growth trajectory.
