Trump admin live updates: GOP megabill could add $4.1T to the debt, CBO says

A new Congressional Budget Office (CBO) analysis projects President Trump's recently passed tax cut and spending bill will add $4.1 trillion to the national deficit over the next decade, an increase from the previously estimated $3.4 trillion for the Senate's version. This legislation is now expected to increase debt held by the public by 9.5 percentage points relative to CBO's January 2025 baseline GDP projections by the end of 2034, indicating a substantial long-term fiscal impact.

Analysis

A new analysis by the nonpartisan Congressional Budget Office (CBO) indicates a significant deterioration in the long-term U.S. fiscal outlook resulting from the recent tax and spending bill. The legislation is now projected to increase the national deficit by $4.1 trillion over the next decade, a substantial upward revision from the $3.4 trillion previously estimated. This new figure incorporates an additional $718 billion in debt-servicing costs, highlighting the compounding effect of increased borrowing. Critically, the CBO projects this will expand debt held by the public by 9.5 percentage points relative to GDP by the end of 2034, based on its January 2025 baseline. This updated forecast provides a more severe quantitative measure of the law's long-term impact on U.S. sovereign debt, introducing a key factor for macroeconomic risk assessment.

Key Decisions for Investors

• Investors should anticipate potential upward pressure on long-term Treasury yields, as the increased supply of government debt to fund higher deficits may require higher rates to attract buyers.
• The projected increase in the debt-to-GDP ratio could introduce long-term headwinds for the U.S. dollar and heighten sovereign risk; therefore, monitoring credit default swap spreads and currency markets for signs of stress is warranted.
• Consider re-evaluating exposure to interest-rate-sensitive sectors, as a steeper yield curve could negatively impact valuations for high-duration assets like growth stocks and certain fixed-income instruments.
• Factor the heightened fiscal risk into macroeconomic models, as sustained large deficits could eventually constrain the government's ability to respond to future economic downturns with further stimulus.
