How has US national debt trended compared to EU countries since 2010?
Executive Summary
Since 2010 the United States’ national debt has risen sharply in absolute terms and as a share of GDP, surpassing typical EU averages and many individual member states; by 2024–2025 U.S. debt stood near or above 118–121% of GDP while the EU average clustered around the low‑to‑mid 80s percent range (and the Eurozone near 91% at its 2020 peak) [1] [2] [3]. The broad picture: U.S. debt growth has been more pronounced and sustained, whereas EU outcomes are heterogeneous — some members reduced or stabilized ratios while others, notably Greece, remained exceptionally high [4] [2] [5].
1. Why the U.S. climbed faster — Spending, tax policy and crisis shocks that mattered
From 2010 onward the U.S. national debt expanded in absolute dollars from roughly $13.6 trillion in 2010 to about $35–38 trillion by 2024–2025, a more than 160% increase in public debt measured in nominal terms; this growth reflects tax cuts, large fiscal stimulus packages, pandemic-era spending, and persistent deficits rather than a single isolated shock [4] [1] [6]. Analysts note the U.S. debt-to-GDP ratio crossed well into triple digits in recent years — figures cited include around 118.8% (October 2025) and projections near 121% for 2024 — placing the U.S. above the World Bank’s cited 77% threshold associated with growth slowdowns and well above the EU average [1] [3] [7]. This pattern shows the U.S. relied on sustained deficit financing across multiple policy decisions and crisis responses, producing a continuous upward trajectory rather than short-lived spikes.
2. EU’s mixed picture — Convergence, divergence, and the Stability & Growth Pact shadow
Across EU members the trend since 2010 has been heterogeneous: the EU aggregate government debt rose from roughly 62% of GDP in 2010 to near 90% in 2020 amid the pandemic, then moderated toward the low‑to‑mid 80s percent by 2024 (EU aggregate ~83.5% and Eurozone ~90.9% at peak) [2] [7]. Individual members diverged sharply: Germany’s ratio remained substantially lower than the U.S., many Northern and central members kept moderate ratios, while Greece and a few southern economies sustained very high levels (Greece >180% in 2020). The EU’s fiscal framework — the Stability and Growth Pact — influenced national choices, and debate persists about whether these rules constrained recovery or forced fiscal consolidation in some states [4] [2] [5]. The result: aggregate EU debt rose but remained below U.S. levels on average, with strong cross‑country variation.
3. Comparing apples to apples — debt-to-GDP is the critical lens
Absolute dollar comparisons are misleading given size differences; the clearest comparison uses debt-to-GDP ratios, where the U.S. has outpaced the EU average since the early 2020s. Sources indicate the EU average hovered around the low‑80s percent of GDP while the U.S. reached roughly 118–121% in recent years, meaning the U.S. carried a higher debt burden relative to economic output [7] [1] [3]. Several EU members remained under the 60% Stability and Growth Pact threshold through parts of the decade, and others cut ratios after crisis peaks. The U.S. trend shows sustained elevation above most EU averages, implying different fiscal trajectories and structural responses to shocks such as the 2008 aftermath, sovereign debt episodes in Europe, and the COVID pandemic.
4. Outliers that shape the averages — Greece, the U.K., and Germany tell different stories
Specific EU cases matter: Greece’s debt remained among the highest in the EU (over 180% in 2020) and kept the EU’s upper range elevated, while the United Kingdom projected a fall from 87% in 2022 to 70% by 2027, indicating national recovery or consolidation paths distinct from the U.S. [4]. Germany’s debt ratio was substantially lower than the U.S. in 2020 and thereafter, reflecting different macroeconomic and fiscal policy mixes. These outliers demonstrate that the EU is not monolithic: averages mask diverging national policies, and several EU members managed to reduce or stabilize debt-to-GDP ratios even as U.S. ratios continued to climb [4] [2].
5. What the numbers leave out — composition, interest costs and fiscal space matter
Debt totals and ratios omit critical dimensions: who holds the debt (intragovernmental vs public), the maturity profile, interest‑rate sensitivity, and revenue capacity. U.S. debt includes large intragovernmental holdings and is influenced by interest costs and monetary policy; EU members face distinct borrowing mixes, domestic creditor bases, and monetary union constraints for euro‑area states. These structural features affect sustainability and policy options despite similar headline ratios. Sources emphasize that composition and institutional context alter how comparable those percentages really are across the Atlantic [6] [2].
6. Bottom line — higher and more persistent U.S. indebtedness, diverse EU outcomes
Since 2010 the clear pattern is higher and more persistent U.S. indebtedness relative to EU averages, with U.S. debt-to-GDP moving into the 118–121% range by the mid‑2020s while the EU aggregate clustered around the low‑80s percent and the Eurozone peaked near 91% in 2020. The EU experience is heterogeneous, with some countries improving ratios and others remaining high; the U.S. record shows consistent absolute and relative increases driven by policy choices and crisis responses. These differences matter for future fiscal tradeoffs, interest costs, and policy flexibility [1] [4] [2] [3].
