The US national debt.
Can it be fixed? The honest math.
Federal debt held by the public is approximately 101% of GDPGross Domestic Product (GDP)The total value of all goods and services produced in a country in one year. and rising. The Congressional Budget Office projects net interest payments alone will exceed $2 trillion per year by 2036. This page walks through the real menu of options and explains why one outcome is almost certain.
U.S. national debt is $39.7 trillion as of 2026-07-28. Annual interest now exceeds defense spending at ~$1T/yr. No politically plausible mix of tax hikes and spending cuts closes the deficit. The realistic resolution is financial repressionfinancial repressionImagine you owe someone $100. If you can persuade them to accept repayment in dollar bills and you quietly print more bills so each one buys less, your debt shrinks in real terms without you officially defaulting. Governments do this with their debt by keeping interest rates below the rate of price increases for years at a time. Savers pay for it.Full definition: negative real rates that gradually inflate the debt away.
- Debt-to-GDP ratio: ~125% as of 2025. The historical danger zone (per Reinhart & Rogoff) starts around 90%.
- Interest cost: ~$1T/yr and rising as older low-rate bonds mature and refinance at higher rates.
- The deficit is structural: Social Security, Medicare, defense, and interest consume ~85% of federal revenue.
- Historical resolution paths: growth (unlikely at this scale), austerity (politically impossible), default (won't happen with a printing press the US has had since leaving the gold standard in 1971), or inflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition/financial repression (most likely).
- This is the macro case for hard assets. When the debt can only be managed by debasing the currency, you want assets denominated in something other than that currency.
The US will not default on its debt. It will inflate it away. Sustained negative real interest rates over 20+ years is the only politically viable path. The people paying that bill are anyone holding dollars, bonds, or fixed-dollar promises. This is the core thesis behind holding scarce assets.
Section 1 · The current numbers

Section 2 · The 2031 inflection: when the math breaks
CBO projects that the average interest rate on US debt (r) will exceed nominal GDP growth (g) by approximately 2031 verify×DON'T TRUST, VERIFYClaim: CBO projects r > g crossover near 2031.Verify at: CBO Feb 2026 Budget and Economic Outlook ↗CBO publishes the projected average interest rate on debt and nominal GDP growth in the appendix tables. The crossover year shifts year to year; check the most recent outlook.. This is the debt-spiral threshold.
When the rate of interest on debt exceeds the growth rate of the economy, debt grows faster than the economy's ability to pay it. Even with zero new deficits, the existing debt compounds at a faster rate than GDP grows. New spending isn't required for the situation to worsen. Economists call this r > g verify×DON'T TRUST, VERIFYClaim: The r > g formulation is standard public-finance economics.Verify at: Blanchard, "Public Debt and Low Interest Rates," AER 2019 ↗Olivier Blanchard's 2019 AEA presidential address is the canonical recent reference; the underlying math goes back to Domar (1944) and is in any public finance textbook..
The US can grow its way partially out of the problem. Debt/GDP can stabilize or decline if growth exceeds interest costs. Productivity surges, immigration, and tax-base expansion all help.
Without deliberate policy action, debt/GDP worsens automatically regardless of new spending decisions. Reaching primary balance is no longer enough; you need to overshoot to interrupt the compounding.
Section 3 · The five paths out
Every proposed solution falls into one of five categories. Each is summarized with what would be required and a candid assessment of likelihood.
Required: sustained 3.5%+ real GDP growth for two decades.
What could produce it: AI-driven productivity surge. CBO already prices in some AI productivity benefit in baseline projections verify×DON'T TRUST, VERIFYClaim: CBO's recent outlooks include AI-related productivity assumptions.Verify at: CBO Feb 2026 Outlook ↗ · CBO long-term outlook ↗CBO has begun referencing AI's potential productivity contribution in the macro discussion sections. Magnitudes are highly uncertain..
Honest assessment: possible but not bankable. The US has not sustained 3.5% real growth for a decade since the 1990s verify×DON'T TRUST, VERIFYClaim: Last decade of sustained 3.5%+ real growth was the 1990s.Verify at: FRED real GDP growth series ↗Real GDP growth averaged 3.7% in the 1990s vs ~2.3% in 2010s and ~2.0% projected for 2020s baseline..
Required: approximately 5-6% of GDP in new tax revenue.
What this means: taxing only households earning over $400,000 raises approximately 1-2% of GDP per major analyses. Closing the gap requires broad-based tax increases that include the middle class verify×DON'T TRUST, VERIFYClaim: Top-end-only tax increases raise ~1-2% of GDP, not enough to close a 5-6% gap.Verify at: CBO Options for Reducing the Deficit ↗ · Tax Policy Center revenue estimates ↗CBO publishes scored revenue options. Top marginal-rate increases and surtaxes on $400k+ income score in the 0.5-2% of GDP range, not the 5%+ needed to close the structural deficit..
Honest assessment: politically non-viable. No major party proposes enough revenue increases to close the structural gap on the tax side alone.
Required: major spending cuts.
The constraint: mandatory spending (Social Security, Medicare, Medicaid, interest) is approximately 75% of the budget today and rising to 83% by 2056. All discretionary spending combined (defense plus everything else) is approximately 17-25% of the budget. Eliminating all discretionary spending is not enough to close the deficit.
Honest assessment: entitlement reform is required for fiscal sustainability and politically catastrophic in any single election cycle. No politician campaigns on Social Security cuts and wins.
Required: sustained negative real interest rates. Inflation runs above the average interest rate on outstanding debt for 20+ years.
Historical precedent: the US did exactly this after World War II. Debt/GDP dropped from approximately 106% in 1946 to approximately 23% in 1974, primarily through nominal growth and inflation, not spending cuts verify×DON'T TRUST, VERIFYClaim: US debt/GDP fell from ~106% to ~23% between 1946 and 1974, mostly via inflation and growth.Verify at: FRED debt-to-GDP historical series ↗ · Reinhart and Sbrancia, "The Liquidation of Government Debt" ↗Reinhart and Sbrancia (NBER, 2011, IMF, 2015) document that financial repression contributed an annual liquidation rate of about 3-4% of GDP across advanced economies in the postwar period..
The mechanism: the Federal Reserve keeps rates below inflation (financial repression). Savers earn negative real returns on dollars and bonds. The real value of the debt shrinks. The government's fixed-dollar liabilities become cheaper in real terms.
Honest assessment: this is the default outcome by political elimination. It does not require anyone to vote for it. It happens silently through monetary policymonetary policyThe central bank's control of money supply and interest rates to influence the economy..
Required: Congress votes to pay creditors less than they are owed.
Historical precedent: virtually no modern developed economy has explicitly defaulted on debt issued in its own currency.
Honest assessment: will not happen. The Fed can always print to service debt. Default is always optional for a country that issues debt in its own currency. Inflation is not the same as default but it produces a similar real-terms result.
Section 4 · The realistic outcome
The financial-repression playbook used after World War II is the historical template. Five tools are typically used in combination.
- Sustained 3-4% inflation rather than the 2% target. Slightly above-target inflation, normalized over 15-20 years, does the heavy lifting.
- Yield-curve influence. The Fed buys the long end of the Treasury market on rate spikes, keeping nominal long rates artificially low. Japan ran explicit yield-curve control 2016-2024 verify×DON'T TRUST, VERIFYClaim: Bank of Japan operated explicit yield-curve control 2016-2024.Verify at: Bank of Japan policy framework ↗YCC was introduced September 2016 and gradually unwound through 2024..
- Marginal entitlement reform. Means-testing, slowly rising retirement ages, COLACost-of-Living Adjustment (COLA)An automatic raise to Social Security or pension payments each year, sized to match how much prices have gone up. adjustments. Each change saves money without being a "cut" in any single election cycle.
- Tariffs as a stealth tax. CBO estimates approximately $3 trillion in deficit reduction from current tariff levels over the 10-year projection window verify×DON'T TRUST, VERIFYClaim: CBO scores current tariff levels at roughly $3T over 10 years.Verify at: CBO Feb 2026 Outlook ↗Tariff revenue figures appear in the revenue projections appendix and are revised when tariff policy changes..
- AI productivity tailwind. If AI materially raises productivity, GDP grows faster and the debt/GDP ratio improves through the denominator. CBO has begun including AI productivity assumptions in projections.
No one will say this out loud, but the playbook is already running. Inflation is structurally higher. Long-term yields are managed. Entitlements get tweaked. Tariffs collect more revenue. AI is hoped for. None of these alone fixes the debt. All of them together, sustained over decades, can stabilize the ratio without requiring Congress to vote for unpopular cuts or tax increases.
Section 5 · The math on a "real fix"
Stabilizing debt/GDP at current levels (not reducing it) requires approximately $750-900 billion per year in permanent deficit reduction verify×DON'T TRUST, VERIFYClaim: Stabilizing debt/GDP requires roughly $750-900B/yr in permanent deficit reduction.Verify at: Peterson Foundation Solutions Initiative ↗ · Brookings stabilization analysis ↗Estimate depends on assumed interest rates and growth path. Most independent budget analysts converge on the $0.7-1T per year range to stabilize the ratio..
What that combination looks like in practice:
- Cutting all non-defense discretionary spending by half: approximately $400-500 billion per year.
- Plus raising every income tax bracket by 4 percentage points: approximately $400-500 billion per year.
- Combined total: approximately $800-1,000 billion per year.
Even this combination barely stabilizes the ratio. It does not reduce it.
No political coalition that could pass this combination currently exists. The pairing of who bears the spending cuts and who pays the tax increases creates opposition from every direction. The honest conclusion: the deficit will not be closed through austerity or tax increases alone. The resolution is a combination of modest reforms and sustained real debasement over decades.
The debt ceiling: what it is and what it is not
What it is
A statutory limit set by Congress on the total amount of debt the Treasury can issue. When the ceiling is reached, the Treasury cannot borrow more. It can use "extraordinary measures" - accounting maneuvers like suspending investments in federal pension funds - to delay actual default for weeks or months. The "X-dateX-dateThe day the US Treasury exhausts extraordinary measures during a debt-ceiling standoff and would default if the ceiling is not raised. Predicted by CBO. Has never been hit in US history.Full definition" is when those measures are exhausted and default becomes imminent verify×DON'T TRUST, VERIFYClaim: The US debt ceiling is a statutory limit on Treasury borrowing; "extraordinary measures" temporarily delay reaching it.Verify at: US Treasury debt limit page ↗ · CBO federal debt resources ↗CRS reports document the specific extraordinary measures historically used: suspension of G-Fund investments, exchange-stabilization fund draws, and similar accounting moves..
What it is not
The debt ceilingdebt ceilingA US statutory limit on how much debt the Treasury can issue. Does not limit spending Congress already authorized; only limits whether the Treasury can borrow to pay for it. Has been raised more than 100 times since 1917 without ever being formally breached.Full definition does not limit new spending. Congress separately appropriates spending. The ceiling only affects whether the Treasury can borrow to pay for what Congress already authorized. The analogy is ordering dinner at a restaurant, then arguing about whether to pay the check that already arrived. The check is for the meal you ordered.
Most economists consider the debt ceiling structurally incoherent for this reason. Spending decisions and borrowing authority should be decided together, not separately. Several other developed countries link the two automatically.
What happens if it is not raised
The Treasury would have to prioritize payments. Some obligations - Treasury bond interest, Social Security payments, federal salaries - would have to be delayed or reduced. A formal default on Treasury debt would be unprecedented. Treasury bonds are the "risk-free" benchmark for the entire global financial system. The ripple effects would include a sharp rise in Treasury yields (falling bond prices), rising mortgage rates and corporate borrowing rates, dollar depreciation, and broad financial-market disruption. Possible loss of US reserve currencyreserve currencyThe money other countries' governments and central banks hold in large amounts to pay for international trade and to back their own currencies. The US dollar fills this role today and has since the 1940s. status over time is on the table.
The historical record
The debt ceiling has been raised, suspended, or modified more than 100 times since 1917. It has never actually been breached to formal default. The brinkmanship itself creates costs: in 2011, Standard & Poor's downgraded the US credit rating from AAA to AA+ during a ceiling standoff even though default was avoided verify×DON'T TRUST, VERIFYClaim: S&P downgraded the US sovereign credit rating from AAA to AA+ in August 2011 during a debt-ceiling standoff.Verify at: S&P Global Ratings, August 5, 2011 ↗Fitch followed with a 2023 downgrade. Moody's downgraded in May 2025. The big-three downgrades all cite political-process risk around the debt limit..
What this means for your money
- Each debt-ceiling standoff raises short-term Treasury yields as investors demand a premium for the small but non-zero default risk near the X-date.
- Money market funds that hold short-term Treasuries can wobble. SPAXX and FDLXX hold government securities whose prices fluctuate during these episodes.
- If you hold short-durationdurationA measure of how sensitive a bond price is to interest rate changes. A bond with 10-year duration falls roughly 10% in price when rates rise 1 percentage point. Longer duration = more interest rate risk. Treasuries or T-bills maturing near a known X-date, their prices may fall and yields spike briefly.
- The practical response is small: keep a month or two of expenses in FDICFederal Deposit Insurance Corporation (FDIC)The US agency that insures bank deposits up to $250,000 per depositor if a bank fails.-insured accounts during ceiling standoffs, and avoid concentrating in T-bills maturing exactly when the deadline lands.

Crowding out and Ricardian equivalence
Crowding out
When the government borrows heavily, it competes with private borrowers for available savings. Higher demand for borrowed funds pushes up interest rates. Higher rates reduce private investment because firms borrow less to build factories, hire, and expand. Government spending displaces private spending, partly or fully.
Empirically, crowding outcrowding outWhen government borrowing competes with private borrowing for available savings, pushing up interest rates and reducing private investment. More significant when the economy is near full capacity, less significant during slack periods.Full definition is contested in magnitude and timing. When the economy has slack (high unemployment, idle capacity), crowding out is minimal because there is no real competition for idle savings. When the economy is at full capacity, crowding out is significant. With a global capital market, US borrowing draws in foreign savings, which reduces domestic crowding but appreciates the dollar and hurts US exports (capital inflows match current-account deficits, by accounting identity).
Ricardian equivalence
Robert Barro's 1974 extension of David Ricardo's earlier insight argues that rational households know that government borrowing today implies higher taxes later. They save more today to pay those future taxes. Government spending financed by debt has the same effect as government spending financed by taxes, because private saving rises dollar-for-dollar to offset the deficit. If true, fiscal stimulus does not stimulate verify×DON'T TRUST, VERIFYClaim: Robert Barro's 1974 paper "Are Government Bonds Net Wealth?" formalized Ricardian equivalence as a modern hypothesis.Verify at: Barro (1974), Journal of Political Economy 82(6) ↗Empirical evidence finds Ricardian equivalence does not fully hold: people are not perfectly rational, do not live forever, and face borrowing constraints. Partial offsets are real, full offsets are rare..
The empirical record: Ricardian equivalenceRicardian equivalenceThe contested theory that rational households save more when government deficits rise, anticipating higher future taxes. If true, fiscal stimulus does not stimulate. The empirical record finds it partially holds, not fully.Full definition fails in practice. People are not perfectly forward-looking, do not all live long enough to see the higher taxes, and face borrowing constraints that prevent the smoothing the theory assumes. But partial Ricardian effects are real. Not every dollar of deficit spending translates to a dollar of additional demand. Some leaks into precautionary saving.
What this means for your money
- Large fiscal expansions tend to push interest rates up at the long end of the curve, which raises mortgage rates and corporate borrowing rates regardless of what the Fed does at the short end.
- The "stimulus does not stimulate" critique is a partial Ricardian story. The mainstream evidence is that stimulus does work in deep recessions and works less well near full employment. The position depends on the cycle phase, not on absolute deficit size.
- For investors: the practical consequence is that long-bond duration becomes risky in periods of large, persistent deficits even when short rates are stable.
When interest outgrew the military: the line the US just crossed
Section 1 noted in passing that net interest now exceeds defense. That crossover deserves its own treatment, because it is the single clearest signal that the debt has moved from a long-run worry to a present-tense constraint. In fiscal year 2024, federal net interest spending reached approximately $881 billion, edging past both national defense (approximately $874 billion) and net Medicare (approximately $874 billion) verify×DON'T TRUST, VERIFYClaim: In FY2024 net interest (~$881B) surpassed both national defense (~$874B) and net Medicare (~$874B).Verify at: CRFB, citing CBO ↗ · House Budget Committee ↗Net interest tripled from ~$345B in 2020 to ~$881B in 2024 on the back of higher rates and a larger debt stock. Treasury's gross interest figure for FY2024 is higher (~$909B); the ~$881B figure is net of intragovernmental interest. Both clear defense.. Interest is now the third-largest line in the federal budget, behind only Social Security and total health programs.
This was not a rounding-error crossing. Net interest tripled from roughly $345 billion in 2020 to approximately $881 billion in 2024, and CBO projects it cleared $1 trillion in FY2025 and keeps climbing verify×DON'T TRUST, VERIFYClaim: Net interest passed $1 trillion in FY2025 and continues rising.Verify at: CBO Monthly Budget Review, Summary for FY2025 ↗ · CRFB ↗CBO's February 2025 baseline projected ~$952B for FY2025; the FY2025 actuals confirmed net interest above the $1T mark. The trajectory is toward ~$2.1T by 2036 (see Section 1).. The ranking holds across both the partial-year Treasury data and the full-year totals.
| FY2024 budget line | Approx. outlay | Trajectory |
|---|---|---|
| Net interest | ~$881 billion | Tripled since 2020; past $1T in FY2025, heading toward ~$2.1T by 2036 |
| National defense | ~$874 billion | Roughly flat as a share of GDP; ~3.0% in 2024 |
| Net Medicare | ~$874 billion | Rising with demographics, but now passed by interest |
Figures are net outlays per CBO and Treasury for FY2024; defense and Medicare round to the same approximate level, both just under net interest. Gross interest (Treasury basis) was higher still at roughly $909 billion.
Ferguson's Law
The historian Niall Ferguson gave this threshold a name. In a February 2025 Hoover Institution paper, he proposes Ferguson's Law: "any great power that spends more on debt servicing than on defense risks ceasing to be a great power." He calls the crossover point the Ferguson limit, "the point at which interest payments and principal repayments on the public debt (together, debt service) exceed defense outlays", and argues that staying above it for an extended period is historically predictive of geopolitical decline, because debt service "draws scarce resources towards itself, reducing the amount available for national security" verify×DON'T TRUST, VERIFYClaim: Niall Ferguson's "Ferguson's Law" holds that a great power spending more on debt service than defense risks decline; the US crossed the "Ferguson limit" in 2024.Verify at: Ferguson, Hoover History Working Paper 202502 (Feb. 2025) ↗Ferguson dates the US violation to 2024, when CBO data put net interest at 3.1% of GDP versus defense at 3.0%, the first time in nearly a century. He notes prior US episodes in 1790–1809, the 1920s, and briefly in Q1 1998..
Ferguson's framing matters because it reframes the debt as a national-security problem, not just an accounting one. By his measure, the US began violating the law in 2024 for the first time in nearly a century, and CBO's own projections show net interest reaching roughly double the defense budget (4.9% of GDP versus 2.5%) by 2049. The point is not that interest payments fund an enemy; it is that every dollar of debt service is a dollar that cannot be spent on anything a voter or a general wants, and that pressure bends the budget toward the politically easy option, which, as Section 3 argued, is debasement. This is the geopolitical face of fiscal dominance: once interest crowds out everything else, the central bank's freedom to fight inflation shrinks.
The disinflation tailwind is reversing
There is a deeper reason the inflate-it-away path (Section 3, Path 4) is likely to run hotter than the postwar template suggests: the structural force that kept inflation low for a generation is going into reverse. From roughly 1990 to 2018, the effective global labor supply available to advanced economies more than doubled, as China and Eastern Europe joined the trading system and the working-age share of the population peaked. A flood of cheap labor and cheap goods held wages and prices down. That was the disinflationary tailwind that made low interest rates and large deficits feel costless.
Charles Goodhart and Manoj Pradhan argue in The Great Demographic Reversal (Palgrave Macmillan, 2020) that this is now flipping. Populations across the developed world and China are aging; working-age cohorts are shrinking; and a rising share of labor must be diverted into elder care precisely as the labor force contracts. Their conclusion is that the demographic dividend that produced three decades of disinflation will become structurally inflationary, pushing up both wages and interest rates verify×DON'T TRUST, VERIFYClaim: Goodhart & Pradhan argue that aging populations and a shrinking labor force reverse three decades of disinflation into an inflationary force that raises interest rates.Verify at: Goodhart & Pradhan, The Great Demographic Reversal, Palgrave Macmillan (2020) ↗Their thesis: the effective labor supply for advanced economies more than doubled 1991–2018 (China + favorable demographics), driving disinflation; aging now reverses it, raising inflation, raising rates, but compressing inequality as labor regains pricing power..
For the debt, this is the worst possible backdrop. Higher structural inflation is exactly what erodes the real value of the debt (the mechanism this page argues is the default outcome) but higher structural interest rates raise the cost of servicing it, accelerating the r > g dynamic from Section 2 and the interest-vs-defense squeeze above. Aging also lifts the mandatory-spending wedge (Social Security and Medicare) at the same time. The postwar liquidation worked partly because rates could be held low against a young, growing population; that demographic gift is now running the other way. For investors, the takeaway reinforces the bond warning throughout this page: a regime of higher-for-longer structural inflation and rates is the historically worst environment for long-duration bonds, and the case for scarce assets gets stronger, not weaker.
Section 6 · What this means for your money
If the path is financial repression (sustained negative real rates for 20+ years) the impact splits into two columns: who pays and who benefits.
- Holders of cash. Real value erodes at the inflation rate.
- Holders of fixed-rate bonds. Real value declines as inflation runs above the yield.
- Recipients of fixed-dollar promises. Pension holders, annuity buyers, anyone receiving non-COLA-adjusted income.
- Wage-paid workers. If nominal wage growth lags inflation, real income falls.
- The federal government. Fixed debt becomes cheaper in real terms.
- Holders of hard assets. Real estate, gold, Bitcoin. Nominal values rise with inflation.
- Equity holders. Companies raise prices with inflation, revenues go up in nominal terms.
- Borrowers with fixed-rate debt. A 30-year mortgage at 3% becomes cheaper in real terms if inflation runs at 4%.
The rational response is not panic. It is asset allocationasset allocationHow you divide your money across different types of investments like stocks, bonds, and Bitcoin.Full definition. Productive equity (broad index funds) is the minimum required to stay ahead of inflation. Hard assets (real estate, gold, Bitcoin) offer additional protection. Long-term bonds are historically the worst position in a financial-repression environment.
The US will not default. It will inflate. The bill is paid quietly over 20+ years by anyone holding dollars, bonds, or fixed-dollar promises. The bill is not paid by anyone holding real estate, equity, or scarce assets. This is not opinion. This is the playbook the US used 1946-1974 and Japan has used since 2000. The case for holding scarce assets follows from the math, not from a forecast.
