National debt/deficit to GDP

In 2026, the national debt-to-GDP ratio is projected to rise 3.4% year over year, reaching 127.7%. This increase is driven largely by the 2025 OBBBA, which expands federal spending while cutting tax revenues, including more lenient SALT provisions that are expected to erode federal receipts through 2029. Efforts to trim the federal workforce and reduce select agency funding will provide only limited offset, as higher interest costs and rising outlays for programs such as Social Security and other mandatory benefits continue to push expenditures higher. Defense spending is also set to edge up or remain elevated amid conflicts such as the Iran war, constraining any meaningful pullback in total spending. On the other side of the ratio, GDP growth is expected to remain moderate as inflationary pressures and higher costs weigh on real activity, limiting the denominator's ability to counter rising debt levels.

Over the five-year period from 2021, the national debt-to-GDP ratio underwent significant changes prompted by the COVID-19 pandemic and its economic consequences, which necessitated unprecedented fiscal stimulus through the Families First Coronavirus Response Act and the CARES Act. As unemployment soared, government tax revenues plummeted, leading to a sharp uptick in federal debt to fund rising deficits. As pandemic conditions stabilized, the enactment of the American Rescue Plan Act in 2021 contributed to a reduction in the debt-to-GDP ratio, with pandemic-related spending declining and government revenues showing marginal improvement. The period was characterized by successive GDP growth trajectories, even amid recession fears sparked by increasing interest rates. Inflation, influencing GDP in nominal terms, also contributed to perceived debt reductions by temporarily inflating economic activity metrics.

Yet, national spending expanded under the Biden Administration, notably through initiatives like the Infrastructure Investment and Jobs Act of 2021, which boosted long-term project spending, thereby maintaining elevated expenditure levels. Such spending dampened potential declines in the debt-to-GDP ratio, as increased project funding commitments offset reductions in the federal debt-to-GDP ratio. In 2025, the national debt-to-GDP ratio is increased by 0.2%, reaching 122.5%. The growth is largely attributable to enhanced federal funding aimed at bolstering social services and the defense sector, which has a significant impact on the debt-to-GDP ratio. Meanwhile, the GDP has faced challenging conditions because of the initial and subsequent impacts of tariffs, alongside the extended repercussions following economic shocks absorbed during ongoing trade negotiations led by the Trump Administration. Despite this, this convergence of fiscal policy actions resulted in a measured increase in the debt-to-GDP ratio, achieving a CAGR of 0.1% between 2021 and 2026.
