The National Debt
What it is, how it happened, where it's going, and what history tells us about what happens when a nation can't stop spending more than it earns.
The Constitution gives Congress, not the President, the power to tax, spend, and borrow. That means Congress owns this problem. Here's what they've done with that responsibility.

Fiscal Year: Oct 1, 2026 - Sep 30, 2027💵 Debt vs. Deficit - What's the Difference?
The National Debt
Think of it like a credit card balance. The national debt is the total amount the U.S. government currently owes - every dollar borrowed over all of American history that hasn't been paid back yet. Right now that's about $40.1 trillion. It's the accumulated result of decades of spending more than we took in.
The Annual Deficit
The deficit is what's added to the debt each year. If the government collects $5 trillion in taxes and fees but spends $7 trillion, the deficit is $2 trillion. That $2 trillion gets borrowed, sold as Treasury bonds, and added to the national debt. The deficit is this year's problem; the debt is all the previous years' problems combined.
What About a Surplus?
A surplus is the opposite of a deficit - when the government takes in more than it spends. The U.S. ran surpluses from 1998 to 2001, the only surplus years since 1969. During those years, the government was actually paying down the national debt. Those surpluses ended with the 2001 recession, the Bush tax cuts, and the post-9/11 military spending surge, and the U.S. has run deficits every year since.
Who Owns the Debt?
Not all debt is owed to foreign countries - that's a common misconception. About 81% of the debt is held by the public (Treasury bonds sold to investors). The rest is "intragovernmental debt," money the government borrowed from its own trust funds like Social Security.
Japan (~$1.1T) and the United Kingdom are the largest foreign holders; China (~$0.75T), long in second place, fell to third in 2025. Their ability to sell holdings rapidly is a genuine systemic risk.
⚖️ Is the Debt "Good" or "Bad"?
This isn't a simple question, and anyone who tells you it is is probably selling something. Here's the honest answer: some debt is normal and manageable; too much debt becomes dangerous.
The case for borrowing
Governments legitimately borrow for large investments (wars, infrastructure, recessions) where paying upfront is impossible. WWII required borrowing. The 2008 bank bailout and 2020 COVID relief required borrowing. A government that never borrows can't respond to emergencies.
The danger zone
When debt grows faster than the economy indefinitely, eventually the interest payments crowd out everything else. In FY2024, gross interest on Treasury securities topped $1 trillion, and net interest edged past the defense budget. That trillion paid zero teachers, built zero roads, and funded zero research. It's money simply servicing past decisions.
The death spiral risk
If creditors begin to doubt the U.S. can repay, they demand higher interest rates to compensate for the risk. Higher rates mean more of the budget goes to interest, leaving less for everything else, forcing more borrowing, which raises rates further. This is called a 'debt spiral' and it's how Greece and Argentina collapsed.
🏛️ Congress's Constitutional Responsibility
Article I, Section 8 of the Constitution gives Congress, and only Congress, the power to tax, borrow money, and appropriate funds. The President proposes a budget; Congress enacts it. This was a deliberate design: the Founders feared executive control of the purse as the road to tyranny.
The Budget Process (As Designed)
- 1President submits budget proposal by first Monday in February
- 2House and Senate Budget Committees each write a budget resolution
- 3Full Congress passes a joint budget resolution (sets overall spending levels)
- 412 Appropriations Subcommittees each write a spending bill for their area
- 5Full Congress passes all 12 appropriations bills
- 6President signs them - government funded for the fiscal year (Oct 1 - Sep 30)
The Budget Process (In Reality)
Congress has passed all 12 appropriations bills on time exactly four times since 1977, the year the current budget process began. The other years? Continuing resolutions, omnibus packages, near-shutdowns, actual shutdowns, and last-minute deals. The 12-bill process has effectively been abandoned. Congress now operates on a perpetual emergency budget, kicking hard decisions down the road until the next crisis.
📈 The Debt Since 1791
The U.S. has carried debt since its first day - the Revolutionary War left the new nation $75 million in debt. What changed is the scale. The debt remained manageable for 150 years. Then WWII, the Cold War, tax cuts without spending cuts, and the post-2001 era of wars and financial crises sent it parabolic.
Key Inflection Points
The Only Time America Was Debt-Free
President Andrew Jackson paid off the national debt entirely on January 8, 1835, the only time in American history. It lasted about a year before a financial panic and depression required new borrowing.
Civil War Debt
The Civil War pushed debt from $65 million to $2.8 billion, a 43x increase. The Union financed the war through the first income tax, the first paper currency (greenbacks), and massive bond sales marketed directly to citizens.
WWII Peak - 119% of GDP
WWII pushed debt-to-GDP to 119%, higher than today. But postwar economic growth, combined with high tax rates on the wealthy (up to 91%), gradually reduced the ratio over the next three decades without paying off the nominal debt.
The Reagan Revolution
Reagan cut taxes dramatically (top rate from 70% to 28%) while increasing defense spending. The theory that tax cuts would pay for themselves through growth did not materialize. Debt nearly tripled from $994 billion to $2.9 trillion during his presidency.
The Surplus Years
The dot-com boom, Clinton-era tax increases, spending restraint from the 1997 Balanced Budget Act, and the 'peace dividend' from the Cold War's end produced four consecutive surplus years. The CBO projected the debt would be fully paid off by 2012.
The Deficit Returns
The 2001 Bush tax cuts, 9/11 security spending, the Afghanistan and Iraq wars (financed entirely through borrowing - the first wars in American history not accompanied by a tax increase), and the 2008 financial crisis added about $5 trillion in 8 years (from about $5.7 trillion in January 2001 to $10.6 trillion in January 2009).
COVID-19: About $5 Trillion in Relief
Congress approved roughly $5 trillion in COVID relief over about a year - the CARES Act ($2.2T), the December 2020 relief package (~$0.9T), and the American Rescue Plan ($1.9T) - covering stimulus checks, PPP loans, and enhanced unemployment. The debt crossed $30 trillion for the first time in 2022.
🔭 Three Futures
The Congressional Budget Office projects the debt under current law. Below are three scenarios: what happens if nothing changes, what happens with serious fiscal reform, and what happens if spending accelerates. None of these are guaranteed, but they're all plausible.
Status Quo (CBO Baseline)
If Congress continues current policy - spending growth driven by Social Security and Medicare, no major tax changes, recurring deficits of $2-3T/year - debt grows relentlessly. By the 2030s, interest payments alone will exceed defense spending.
The risk: By 2050, interest on the debt is projected to be the single largest line item in the federal budget, consuming over 30% of all federal revenue. At that level, every new dollar of spending must either raise taxes or borrow, with borrowing making the problem worse.
With Serious Fiscal Reform
If Congress combined modest tax increases (returning rates toward 2000-era levels), gradual Social Security adjustments (raising the retirement age, adjusting the formula), Medicare cost controls, and elimination of low-priority discretionary programs, debt growth could be dramatically slowed.
The risk: Every component of this reform is politically toxic. Tax increases face fierce Republican opposition. Social Security changes trigger seniors' outrage. Medicare cuts anger hospital and pharmaceutical industries. The political cost of reform is immediate; the benefit is years away, a formula that systematically favors inaction.
Accelerating Deficits (Stress Scenario)
If a major recession hits, or large new tax cuts are enacted without offsets, or a major war requires emergency spending, or interest rates rise significantly (making existing debt more expensive to refinance), the debt could spiral far beyond CBO projections.
The risk: At some point, economists disagree on exactly when, bond markets lose confidence in the U.S.'s ability to repay. They demand higher interest rates to compensate for perceived default risk. Higher rates mean higher interest payments, which means more borrowing, which means higher rates - a debt spiral. The U.S. has never faced this scenario, but history shows it's not theoretical.
💡 What Would "Solving It" Actually Take?
The Committee for a Responsible Federal Budget estimates that stabilizing the debt-to-GDP ratio at current levels would require roughly $4-5 trillion in deficit reduction over 10 years. For context, that's the equivalent of eliminating the entire defense budget for four years, or raising the top income tax rate to above 60%, or cutting Social Security benefits by 30%. Most realistic solutions involve a combination of all of the above, and require political will that has not existed in Washington in decades.
Committee for a Responsible Federal Budget - crfb.org🔄 The Continuing Resolution Problem
A Continuing Resolution (CR) is Congress's way of admitting it hasn't done its job. When lawmakers can't agree on a budget, which is now almost always, they pass a CR that simply keeps the government funded at roughly last year's levels for a few more weeks or months. Then they pass another one. And another.
The bottom line: Congress has passed all 12 annual appropriations bills on time exactly 4 times in the last 47 years (FY1977, FY1989, FY1995, FY1997). In 43 of the last 47 fiscal years, the government operated on continuing resolutions, omnibus packages, or both. This is not an occasional failure - it is the permanent operating mode of the federal government.
Why Congress Uses CRs Instead of Real Budgets
Avoids hard votes
A real budget requires members to vote for specific spending levels or cuts. A CR avoids those votes - no one can be attacked for cutting veterans' benefits or defense if those numbers never came up for a vote.
Partisan deadlock
The House and Senate are often controlled by different parties, or the same party has enough internal disagreement that a budget majority is impossible. A CR lets both sides declare partial victory by not changing anything.
Kicks the can
CRs fund the government for 45-90 days at a time. Each new CR pushes the deadline into the future. The hope is always that the next deadline will force a real deal, which usually produces another CR.
No enforcement mechanism
There's no constitutional consequence for Congress failing to pass a budget on time, other than a government shutdown, which both parties fear enough to pass CRs but not enough to pass actual budgets.
CR Usage by Period
What CRs Cost the Country
- Programs can't plan. A federal agency on a CR doesn't know its budget for the year - it can't hire staff, sign contracts, or launch new programs.
- Defense readiness suffers. The Pentagon can't start new weapons contracts or make multi-year purchases under a CR, forcing them into more expensive short-term deals.
- Economic uncertainty. Businesses that depend on federal contracts can't plan either. Uncertainty reduces investment.
- The debt grows faster. CRs often don't control spending carefully - they just roll over last year's numbers, including all the inefficiencies.
- It normalizes failure. Every time Congress avoids a shutdown with a CR, it confirms that the deadline means nothing, making real budget discipline even less likely the next year.
The Debt Ceiling: Political Theater
The debt ceiling is a legal limit on how much the U.S. government can borrow. It sounds like a responsible check, but in practice it's largely theater. Congress votes to spend money (through appropriations), which obligates the government to pay its bills. Then Congress separately votes to raise the debt ceiling to pay those same bills it already approved. Refusing to raise the ceiling doesn't prevent new spending - it would cause the U.S. to default on debts Congress already incurred.
⚠️ When Debt Destroys Nations
The United States is not the first powerful country to accumulate enormous debt. History is full of cautionary examples, some of them catastrophic beyond anything most Americans can imagine. These are not abstract economic theories. These are real events that happened to real people, and the pattern of warning signs that preceded them looks uncomfortably familiar.
What Happened
The German government, unable to pay reparations, simply printed money. Hyperinflation exploded: by November 1923, a single US dollar cost 4.2 trillion German marks. Workers were paid twice a day and ran to spend their wages before they became worthless. A wheelbarrow full of cash couldn't buy a loaf of bread. Savings accounts were wiped out overnight.
Political Consequences
The economic chaos destroyed the middle class, obliterated savings, and created the conditions of desperation and resentment that Adolf Hitler exploited to rise to power a decade later. Many historians see the 1923 hyperinflation, together with the Great Depression that followed, as part of the economic turmoil that helped the Nazis win support on the road to World War II.
Warning Signs That Were Ignored
- Government printing money to cover deficits
- Loss of confidence in currency
- Rising debt-to-GDP ratio past 100%
- Political instability preventing reform
The U.S. Parallel
The U.S. has a reserve currency advantage Germany lacked - the dollar is the world's reserve currency, giving the U.S. far more borrowing flexibility. However, that status is not permanent and is slowly being challenged.
What Happened
Argentina defaulted on $93 billion in sovereign debt, the largest sovereign default in history at the time. The government froze bank accounts (Argentines could only withdraw $250/week from their own savings). The peso lost 70% of its value in weeks. Unemployment hit 25%. Riots erupted. Five presidents resigned in two weeks. The middle class was economically destroyed.
Political Consequences
Decades of economic instability followed. Argentina has now defaulted on its sovereign debt nine times, one of the highest totals of any country. Each default makes the next borrowing crisis worse as creditors demand higher interest rates.
Warning Signs That Were Ignored
- Debt denominated in foreign currency
- Inability to devalue currency to adjust
- IMF bailouts masking structural problems
- Political inability to pass austerity
The U.S. Parallel
The U.S. borrows in its own currency (unlike Argentina), which prevents the specific 'currency peg' failure mode. But Argentina's political paralysis, an inability to make hard fiscal choices, is a pattern that echoes in Washington's continuing resolution culture.
What Happened
Greece required three successive international bailouts totaling 289 billion euros. In exchange, it was forced to implement savage austerity: pensions cut by up to 40%, minimum wage cut 22%, hospitals closed, unemployment hit 27% (50%+ for youth). GDP shrank by 25%, worse than the U.S. Great Depression. The pain lasted nearly a decade.
Political Consequences
The crisis produced political extremism on both left and right, elected a radical left government (Syriza) that briefly threatened to leave the euro, and left lasting economic and psychological damage. Greece's economy has still not fully recovered.
Warning Signs That Were Ignored
- Debt-to-GDP above 100% with no credible plan
- Interest payments consuming large share of tax revenue
- Structural deficits (spending exceeds revenue every year)
- Political promises outpacing economic reality
The U.S. Parallel
The U.S. debt-to-GDP ratio is now ~123%, above the threshold where Greece began its crisis. The key difference is the U.S. dollar's reserve currency status and the depth of U.S. capital markets. But the structural deficit, spending more than revenue every year, is identical.
What Happened
Zimbabwe experienced the second-worst hyperinflation in recorded history. By November 2008, the monthly inflation rate was 79.6 billion percent. The government issued a $100 trillion banknote. Zimbabweans carried cash in wheelbarrows. The currency became worthless, and the government eventually abandoned it entirely and switched to U.S. dollars.
Political Consequences
The economy collapsed entirely. Life expectancy fell from 60 to 43. Over 3 million Zimbabweans fled the country. The Mugabe government survived by maintaining control of the military and printing money, but the country was destroyed.
Warning Signs That Were Ignored
- Complete loss of central bank independence
- Debt monetization (printing money to pay debts)
- Destruction of productive economic base
- Political repression preventing accountability
The U.S. Parallel
Zimbabwe's path required a complete breakdown of institutional constraints that the U.S. still has in place - an independent Federal Reserve, functioning courts, and democratic elections. The Zimbabwe scenario requires not just bad fiscal policy but the complete collapse of institutions.
What Happened
Debasement caused inflation (prices rose 1,000% between 200-300 AD). Trade collapsed as merchants refused Roman coinage. Soldiers demanded payment in gold, not debased coins. The government could no longer pay its army reliably. Provinces began issuing their own currencies. Central authority crumbled. The western empire fragmented into successor kingdoms by 476 AD.
Political Consequences
The fall of the Western Roman Empire was followed by centuries of declining literacy, urban life, trade, and central government in Western Europe. Historians debate how much fiscal strain caused the collapse, but it is often cited as a warning about what happens when a state can no longer pay for its commitments.
Warning Signs That Were Ignored
- Currency debasement to pay debts
- Military costs exceeding revenue
- Loss of provincial tax base
- Political instability preventing long-term planning
The U.S. Parallel
Currency debasement in Rome is analogous to modern quantitative easing - the Federal Reserve 'printing money' by purchasing Treasury bonds. The U.S. has done this significantly since 2008. The difference is that modern central banking has tools Rome lacked, but those tools depend on maintaining credibility.
🇺🇸 Could This Happen to the United States?
The honest answer is: not in the ways it happened to those countries, but not impossible in ways uniquely American.
A sudden hyperinflationary collapse like Weimar Germany is extremely unlikely. The U.S. has an independent Federal Reserve with strong institutional credibility, and the dollar's reserve currency status means global demand for dollars is enormous. A sudden default like Argentina is also unlikely - the U.S. borrows in its own currency and can always print more of it, at least in the short term.
The more realistic risk is a slow deterioration: rising interest rates driven by growing debt concerns, crowding out of productive investment, gradual loss of the dollar's reserve status as countries diversify, political paralysis preventing reform, and eventually a prolonged period of slow growth, high inflation, declining public services, and rising inequality. Not a sudden crash, but a long, grinding decline in American living standards and geopolitical power.
The Roman Empire didn't collapse in a day. It took centuries of slow fiscal deterioration, institutional decay, and gradual loss of the ability to project power before the end came. The warning signs were visible for generations before anyone acted, and by the time they did, it was too late.
"A democracy cannot exist as a permanent form of government. It can only exist until the voters discover that they can vote themselves largesse from the public treasury." - often attributed to Alexander Tytler (1770s). The attribution is disputed, but the warning is not.
