The United States crossed a fiscal milestone this week that few economists wanted to see: the national debt surpassed 100% of GDP for the first time since World War II. But the more revealing story is in the savings accounts, car loans, and kitchen-table calculations of ordinary Americans.
The financial buffer that households and the federal government relied on to absorb shocks is nearly gone — and the Iran war’s inflationary pressure is burning through what little remains.
As of March 31, debt held by the public stood at $31.27 trillion against an estimated $31.22 trillion in GDP over the prior 12 months — a ratio of 100.2%, according to the Committee for a Responsible Federal Budget, citing new Bureau of Economic Analysis data. The last time the US crossed that threshold was 1946, when the postwar ratio peaked at 106%.

“This time the borrowing isn’t borne from a seismic global conflict, but rather a total bipartisan abdication of making hard choices,” said CRFB president Maya MacGuineas.
The cost of carrying that debt is already reshaping the federal budget: interest payments now consume 14% of all government spending — more than the entire defense budget — and are projected to rise to 26% by 2036, according to the Congressional Budget Office.
“Our budget projections continue to indicate that the fiscal trajectory is not sustainable,” CBO Director Phillip Swagel said in February. The CBO projects the debt-to-GDP ratio will reach 108% by 2030 and 120% by 2036, surpassing the postwar record within four years.
The Bureau of Economic Analysis reported the personal saving rate fell to 3.6% in March, the lowest since fall 2022, down from 5.1% in January 2025 and a peak of 5.5% last April.
Americans spent more even as inflation stayed elevated: the PCE price index rose 3.5% year-over-year in March, the highest in three years, driven partly by the Iran war’s impact on energy. Gas prices returned to $4.30 per gallon, costing households roughly $70 more a month at the pump.

The aggregate numbers, however, mask a widening split: higher-income households insulated by asset appreciation are sustaining headline spending, while lower-income Americans pull back. The share of new-car buyers earning under $100,000 fell from 50% in 2020 to 37% last year, according to Cox Automotive. With savings this thin across most of the income distribution, households have little capacity to absorb the next shock.
The auto market shows where that pressure has already landed. In the first quarter of 2026, 30.9% of Americans trading in a vehicle owed more than it was worth — negative equity. The average shortfall hit $7,183, up 42% from five years ago and the second-highest quarterly figure on record, according to Edmunds.
Rather than absorbing the loss, most borrowers roll it into their next loan: 43% of underwater buyers extended new loans to 84 months to keep payments manageable. Buyers with negative equity financed an average of $55,970 — roughly $12,000 more than the typical buyer — pushing average monthly payments to a record $932. The pandemic-era car bubble is now colliding with a normal depreciation curve. The debt followed them.
Consumer confidence reflects the accumulated strain. The Conference Board’s Consumer Confidence Index six-month average for Generation X has fallen to approximately 78 points, the lowest in at least four and a half years. Baby Boomers sit at roughly 83, the weakest since at least October 2021. The Silent Generation has dropped to approximately 91 — also a multi-year low. Generation Z, at around 110, remains below its 2021–2025 range. All four cohorts have been in steady decline since early 2025.
Gallup captures the same mood: a record 55% of Americans say their financial situation is getting worse, the highest share in 25 years of tracking — above readings from both the 2008 financial crisis and the COVID-19 pandemic.
Three years of above-average inflation eroded purchasing power. Pandemic-era financial decisions — oversized car loans, drawn-down savings — hardened into permanent constraints. The Iran war, with no end in sight, adds another. A federal government spending $1.33 for every dollar it collected last fiscal year has little room to respond.
The safety net Americans are counting on most is under the same pressure. Social Security’s retirement trust fund is less than seven years from insolvency; without congressional action, beneficiaries face a projected 24% benefit cut.
