Rising Deficits and Revised Forecasts

The Committee for a Responsible Federal Budget (CRFB) has revised its outlook, projecting that U.S. federal deficits will be nearly $1 trillion higher over the next decade than previously estimated by the Congressional Budget Office (CBO) in January. The new forecast anticipates a cumulative shortfall of $22.7 trillion from fiscal 2026 to 2035, compared to the previous projection of $21.8 trillion. These estimates reflect recent tax, spending legislation and the impact of tariffs implemented during the Trump administration.

Legislative Changes and Tariff Implications

The revised numbers incorporate the fiscal effects of the One Big Beautiful Bill Act alongside existing tariff policies. Although both the CRFB and the CBO exclude dynamic economic growth effects from their forecasts—a methodology that has drawn criticism from the current administration—the CRFB estimates that the tax cuts and new spending measures will add significantly to deficits. According to the CRFB, the associated cost, including interest, could surge by $4.6 trillion through 2035, compared to the CBO’s $4.1 trillion projection through 2034. However, in a partial offset, additional import duty revenues generated by the tariffs are expected to contribute $3.4 trillion over the same period.

Impact on Future Economic Metrics

In its projections, the CRFB also cited new discounting measures such as restrictions on health insurance subsidy eligibility and reductions in foreign aid and related expenditures, which together potentially save an estimated $200 billion over a decade. Despite these adjustments, rising net interest payments on the national debt are cause for concern. CRFB forecasts suggest that these payments will escalate from nearly $1 trillion (3.2% of GDP) in 2025 to $1.8 trillion (4.1% of GDP) by 2035, culminating in a total of $14 trillion over the decade.

Alternative Fiscal Scenarios and Policy Risks

Under an alternative scenario considered by the CRFB, the fiscal outlook deteriorates further, with deficits potentially reaching nearly $7 trillion above the CBO baseline. Central to this scenario is the assumption that a portion of the tariffs, amounting to $2.4 trillion in revenue over ten years, could be negated should the Court of International Trade uphold rulings against many of the new tariffs. Additionally, the extended application of temporary tax measures—including breaks on overtime, tips, and Social Security income—could add an extra $1.7 trillion in deficits. The CRFB warns that if 10-year U.S. Treasury yields remain at current levels, as opposed to declining to 3.8% as forecast by the CBO, interest costs could further increase by about $1.6 trillion through 2035.

Long-Term Debt-to-GDP Trajectories

The revised forecasts suggest a steadily worsening debt-to-GDP ratio. According to the CRFB, the ratio could rise from 118% in the CBO’s January baseline to 120% under their projected scenario, or escalate as high as 134% in the more adverse alternative scenario. These figures underscore the challenges policymakers will face in managing both current fiscal commitments and burgeoning debt in a dynamic global economic environment.
