On April 30, 2026, the Wall Street Journal and the Committee for a Responsible Federal Budget (CRFB) marked the milestone: as of March 31, U.S. federal debt held by the public stood at $31.27 trillion against an estimated $31.22 trillion in nominal GDP over the prior 12 months. The debt-to-GDP ratio crossed 100.2% — the first time the ratio has exceeded 100% outside of the immediate aftermath of World War II.
The ratio matters more than the headline dollar figure. After WWII, the debt-to-GDP ratio peaked at 106% in 1946 and then fell rapidly through the 1950s as the post-war economy expanded faster than the debt grew. The Trump-era trajectory is different. The Congressional Budget Office now projects the ratio will continue rising — to roughly 120% by 2036 and approximately 175% by 2056 — without major policy changes. The U.S. is firmly on track to break the all-time post-WWII record of 106% within this administration's second term.
Trump's proposed FY2027 budget, released in early April, would increase defense spending by more than 40% (driven by the Iran war and the proposed $200 billion supplemental) while cutting nondefense discretionary programs. CBO scoring shows the budget still leaves the debt-to-GDP ratio above 100% throughout the entire forecast window. The total debt itself is now $39 trillion — up from $19.9 trillion when Trump first took office in January 2017. Trump campaigned in 2016 on a promise to eliminate the national debt within eight years.
The context for the milestone is the same set of policy choices that drove debt-to-GDP from a relatively contained ~76% pre-Trump to over 100% now: two Trump tax-cut packages (the 2017 TCJA and the 2025 OBBBA), the unfunded Iran war ($25B disclosed by the Pentagon to date, $200B supplemental being prepared), expanding ICE/CBP funding ($170B+ across two reconciliation bills), and persistent annual deficits exceeding $1.9 trillion in fiscal year 2026. Net interest payments on the debt are projected to exceed $1 trillion in fiscal year 2026 alone — nearly triple the $345 billion paid in 2020. The IMF warned in April that the explosion of U.S. debt is wiping out the historical 'safety premium' on Treasury bonds.
