Trump tax bill to add $3.4tn to US debt over next decade, new analysis finds

Donald Trump's recently enacted tax bill is projected to add $3.4 trillion (CBO) to $4.1 trillion (CRFB, with interest) to the national debt over the next decade. This increase stems primarily from making permanent 2017 corporate tax cuts and new immigration enforcement spending, despite $1.1 trillion in savings from social program cuts. Analysts caution that the bill is expected to yield only "modest, or negative" economic benefits, while also potentially increasing energy costs and leaving 10 million Americans uninsured, further straining the already substantial $36 trillion national debt.

Analysis

According to a new analysis from the nonpartisan Congressional Budget Office (CBO), a recently enacted tax bill is projected to increase the U.S. national debt by $3.4 trillion over the next decade, with the Committee for a Responsible Federal Budget (CRFB) estimating the impact could reach $4.1 trillion when including interest. The primary driver of this deficit expansion is $4.5 trillion in lost revenue from making the 2017 tax cuts permanent, most notably the reduction of the corporate tax rate from 35% to 21%. Offsetting spending cuts, including $1.1 trillion from Medicaid and food stamp programs through stricter eligibility, are insufficient to cover the revenue shortfall. The bill also reallocates capital by removing tax credits for wind and solar development, which could elevate energy costs, while simultaneously directing nearly $170 billion to new immigration and border security spending. Critically, economic modelers from across the ideological spectrum reportedly agree that any sustained economic benefits are likely to be "modest, or negative," challenging the growth-based rationale for the policy and suggesting a deterioration in the nation's fiscal position on top of an existing $36 trillion debt. The CBO also projects significant social impact, with 10 million Americans potentially losing health insurance by 2034.

Key Decisions for Investors

• Investors should re-evaluate exposure to long-duration U.S. sovereign debt, as the projected addition of up to $4.1 trillion to the national debt could increase pressure on Treasury yields and heighten sovereign risk concerns.
• A defensive posture is warranted for investments in the renewable energy sector, which faces direct headwinds from the removal of key tax credits, and in healthcare sectors reliant on Medicaid, which faces significant funding and eligibility reductions.
• Given the consensus that the bill will deliver modest to negative economic benefits, investors should temper GDP growth expectations and monitor for potential stagflationary pressures arising from a higher deficit combined with potentially rising energy costs.
