The United States’ debt burden cannot be reduced by a president acting alone. The figure behind the “$38 trillion” framing is Treasury’s $37.5 trillion of debt subject to the statutory limit on September 30, 2025—not the same measure as the $30.2 trillion of debt held by the public that day. A workable approach would require the president and Congress to make choices about taxes, spending and economic policy, then weigh their effects on deficits, interest costs and households over time.
The latest deficit estimate in the available figures is also a reminder that the problem is ongoing: the Congressional Budget Office (CBO) estimated that the federal deficit for fiscal year 2026 was $2.0 trillion, $218 billion more than in fiscal year 2025. That annual shortfall adds to federal borrowing needs; it is not the total amount of federal debt.

What does the $38 trillion figure measure?
“National debt” is often used broadly, but federal debt figures refer to different things. Treasury’s September 30, 2025 snapshot shows why it matters to name the measure and date rather than treat every headline number as interchangeable.

| Measure | Amount | What it means |
|---|---|---|
| Debt subject to the statutory debt limit | $37.5 trillion on September 30, 2025 | The amount counted under the statutory limit. This is the dated figure closest to the “$38 trillion” headline. |
| Debt held by the public | $30.2 trillion on September 30, 2025, excluding accrued interest | Federal debt held outside the federal government, including by individuals, institutions and other holders. |
| Intragovernmental debt | $7.3 trillion on September 30, 2025 | Federal debt held by government accounts. |
| Statutory debt limit | $41.104 trillion after enactment of Public Law 119-21 on July 4, 2025 | The legal ceiling, not a measure of the amount borrowed. |
These figures are from the U.S. Department of the Treasury’s financial position report. Debt held by the public and intragovernmental debt together describe major components of federal debt, while debt subject to the limit is a separate statutory measure. The debt-limit figure does not mean the government had borrowed exactly $38 trillion from outside investors, nor does the statutory ceiling itself show how much debt was outstanding.
How large is the deficit, and why does it add to the debt?
A deficit is the gap between federal spending and revenue over a period—usually a fiscal year. When spending exceeds revenue, the government must finance the shortfall, which adds to borrowing needs. Debt is the accumulated amount owed under a specified measure; a deficit is a flow over a period.
In its October 8, 2026 Monthly Budget Review, CBO estimated the fiscal year 2026 deficit at $2.0 trillion, $218 billion more than in fiscal year 2025. CBO estimated that revenues rose by $169 billion while outlays rose by $386 billion. It identified net interest, major benefit programs, defense and education among the areas where outlays grew. These are CBO estimates, not a final audited account.
The deficit includes both program spending and interest on existing debt. The primary deficit is the shortfall before net interest; the total deficit includes net interest. That distinction matters because a plan can change the primary deficit while interest on accumulated borrowing continues to affect the total deficit.
What does the CBO’s debt outlook say?
CBO’s February 2026 baseline projected debt held by the public to rise from 101 percent of gross domestic product in 2026 to 120 percent in 2036. The projection used laws in place on January 14, 2026. It is a baseline—a projection under specified assumptions—not a prediction that the ratio must reach that level or a completed-year result.
That baseline also estimated a $1.9 trillion deficit for fiscal year 2026. CBO’s October 8 estimate for the completed fiscal year was $2.0 trillion. The difference reflects distinct forecast vintages: the February figure was a projection based on the law and assumptions then in place; the October figure is CBO’s later estimate of the fiscal year’s deficit.
Debt-to-GDP compares debt held by the public with the annual value of the economy. It helps show the scale of debt relative to the resources that support the economy and government revenues. It does not, by itself, determine whether a particular policy is affordable or what households will experience.
Why do interest rates matter?
When the government borrows, it incurs interest costs. Higher rates can make new borrowing and refinancing more expensive, while accumulated debt means those costs can compound over time and add to future deficits.
In an October 2026 scenario, CBO estimated that interest rates 150 basis points above its baseline would produce $6.0 trillion in additional cumulative deficits over 2026–2036. CBO attributed $4.9 trillion to direct interest costs and $1.1 trillion to debt-service costs—the additional costs associated with the larger deficits and borrowing. This is a scenario, not CBO’s central forecast: it holds other economic variables constant while changing rates. It illustrates exposure to higher rates, not a guaranteed outcome or a complete account of how the economy would respond.
What could Trump and Congress do?
The president can propose a budget, set priorities, negotiate with lawmakers and sign or veto legislation. Congress writes and passes laws on taxes and spending; major changes to those policies require legislative action. Executive actions may affect some fiscal policies, but their scope depends on existing law and can be legally contingent. A presidential budget proposal is not enacted policy, and a president cannot unilaterally implement a comprehensive debt-reduction plan.
Change spending or program rules
Spending reductions could come from changing program eligibility, benefit formulas, funding levels or other rules. The fiscal effect depends on exactly what changes, who is affected, how the rules are implemented and when savings begin. A proposal that lowers projected spending may also reduce benefits or services for particular groups, so a credible assessment should identify both the budget effect and who bears it.
Change taxes and other revenues
Tax changes can raise or reduce federal receipts, depending on the policy and assumptions used to estimate its effects. Compare proposals using scored budget effects over a stated period rather than assuming a headline rate, tax cut or revenue source will automatically improve the budget. CBO’s February 2026 baseline included higher tariffs as reducing projected deficits relative to its prior projections; the baseline still showed substantial deficits. That does not establish that tariffs alone can resolve the debt trajectory.

Support growth without treating it as a substitute for budget choices
Faster economic growth can increase the size of GDP and may raise tax receipts, helping improve the debt-to-GDP ratio. But growth claims depend on their assumptions and should be compared with an identified forecast. They do not replace scoring the specific tax and spending changes in a proposal, or accounting for interest costs.
Account for borrowing costs
Lower borrowing costs would ease pressure on the budget; higher costs can worsen it. CBO’s higher-rate scenario shows the potential scale of that exposure, but it is not a policy lever a president can reliably set by decree. A debt plan should show how its proposed changes affect the primary deficit, total deficit and projected debt service.
How to judge a proposed debt plan
A serious proposal should make its assumptions and trade-offs visible, not rely on a single headline number. Compare plans using the following questions:
- What is the budget effect? Separate the effect on the primary deficit from the effect on the total deficit, which includes net interest.
- What happens to debt relative to the economy? Look for a debt-held-by-the-public-to-GDP trajectory over a stated period, rather than only a one-year savings estimate.
- How do interest and debt service change? Identify whether the estimate includes the budget consequences of additional borrowing or lower borrowing.
- Who pays or loses benefits? Examine the distributional effects of tax changes, program rules and funding decisions.
- When would the effects occur? Distinguish immediate changes from savings or revenues that phase in over several years.
- Can the policy be enacted and implemented? Identify which parts require Congress, which rely on existing authority, and any legal or administrative constraints.
- How sensitive is the estimate? Check the forecast period and assumptions about interest rates, growth, revenues and policy details.
CBO’s policy-options resource estimates the budget effects of selected options; it does not endorse them. As CBO puts it: “For each option, CBO presents an estimate of its effects on the budget but makes no recommendations.”

In October 2024, the Committee for a Responsible Federal Budget (CRFB) estimated that then-candidate Donald Trump’s publicly described campaign proposals would add $7.50 trillion to projected debt through fiscal year 2035 under its central estimate. CRFB’s low-to-high range was $1.45 trillion to $15.15 trillion. The organization assessed campaign proposals, using assumptions where details were unclear; this was not an official government score.
That estimate describes proposals assessed in 2024, not a comprehensive score of current administration policy. It should not be used as though it measures the effect of every policy later proposed or enacted. The available figures do not establish a current comprehensive estimate covering all Trump administration proposals.
What a realistic approach requires
The debt challenge is a multi-year budget problem, so an approach should explain which revenues or spending would change, when those changes take effect, who would feel them and how interest costs alter the result. The president can shape priorities and negotiate, but durable changes to federal taxes and spending generally depend on Congress. Any plan should be judged against a dated forecast and a stated debt measure—not by treating a campaign estimate, an annual deficit and a debt-limit figure as if they answer the same question.
Federal budget figures and projections can change as laws, economic conditions and assumptions change. The figures here therefore retain their measurement dates and forecast periods: Treasury’s debt snapshot is from September 30, 2025; CBO’s baseline was published February 11, 2026; and CBO’s deficit review and higher-rate scenario were published October 8, 2026.
