The US national debt.
Can it be fixed? The honest math.

Section 1 · The current numbers

CBO’s February 11, 2026 baseline puts debt held by the public at 101% of GDP in fiscal 2026 and 120% in 2036. It reports $970 billion of net interest outlays in FY2025 and projects over $1 trillion in FY2026. Those are dated figures and conditional projections, not a live debt clock: the baseline holds tax and spending law fixed, counting budget legislation through January 14, 2026 and earlier cutoffs for economic and trade policy. Read the chart below against its own historical measure, and do not splice a gross-debt line onto a publicly held debt forecast without reconciling the definitions.^[1][2]

Source: OMB Historical Table 7.1 (debt held by the public) and CBO, The Budget and Economic Outlook: 2026 to 2036. The dashed segment is the CBO baseline: 101% of GDP in FY2026, 108% in FY2030, 120% in FY2036. Gross federal debt, which adds what the government owes its own trust funds, runs about 20 points higher and is a different measure.^[1][2]

Section 2 · Rates, growth and primary balances drive the ratio

There is no fixed “2031 breaking point.” The debt path depends on the effective nominal interest rate on outstanding debt (r), nominal GDP growth (g), primary balances and financing adjustments. Any dated projection is conditional on those inputs, not a universal threshold.^[1]

In a simplified model, next year’s debt/GDP equals ((1+r)/(1+g)) × this year’s debt/GDP + next year’s primary deficit/GDP. So r > g raises the debt ratio at primary balance, not at zero total deficit. With zero total deficit and no other financing changes, nominal debt does not compound: the primary surplus has already funded the interest. That is accounting arithmetic, not a forecast.^[1][3]

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.

Paths 1 to 4 reduce to three broad adjustments, and Path 5 sits apart from them. Three paths are possible and they can run together: growth, fiscal adjustment, inflationary adjustment. Default or delayed payment is a separate risk; issuing debt in your own currency does not rule it out.^[1][6]

• Grow out of it. Growth scenario: stronger productivity and nominal GDP lower debt/GDP, but the primary balance and the effective interest rate still decide it. Nothing guarantees it.^[1]
• Tax and cut to a surplus. Fiscal-adjustment scenario: higher revenue and spending reform shrink primary deficits. Who pays and whether it passes depend on the package. “Politically difficult” is not “impossible.”^[1]
• Inflate the debt away. Inflation and repression scenario: unexpected inflation running above fixed nominal yields cuts the real debt burden. Refinancing rates and indexed obligations offset part of that. One path, not the inevitable historical resolution.^[1]

Section 4 · The financial-repression scenario

The financial-repression playbook used after World War II is the historical template. Five tools are typically used in combination.

1. Sustained 3-4% inflation rather than the 2% target. Slightly above-target inflation, normalized over 15-20 years, does the heavy lifting.
2. 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 (archived copy) ↗ Source 7 in the list belowYCC was introduced September 2016 and gradually unwound through 2024..
3. 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.
4. 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 ↗ Source 2 in the list belowTariff revenue figures appear in the revenue projections appendix and are revised when tariff policy changes..
5. 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.

Section 5 · The math on a "real fix"

Getting debt/GDP back to its end-2025 level of 99% in 2056 (holding it, not reducing it) requires permanent spending cuts or tax increases of about 2.33% of GDP a year starting in 2027, roughly $707 billion a year in today's economy, and more if action is delayed verify×DON'T TRUST, VERIFYClaim: Holding debt/GDP at 99% in 2056 requires permanent deficit reduction of ~2.33% of GDP (~$707B/yr in today's economy) starting in 2027 (Brookings, Auerbach & Gale, 2026).Verify at: Peterson Foundation Solutions Initiative ↗ Source 8 in the list below · Brookings Institution, An update on the federal budget outlook (Auerbach and Gale, March 12, 2026) ↗ Source 9 in the list belowEstimate depends on assumed interest rates and growth path. Delaying action, or starting from a current-policy baseline instead of current law, raises the figure..^[9]

Illustrative stock-flow worksheet (not U.S. current figures): start with $1,000 billion debt held by the public; collect $400 billion revenue; spend $450 billion excluding net interest. The primary deficit is $50 billion. Add $50 billion net interest: total deficit is $100 billion. With no other financing adjustments, year-end debt becomes $1,100 billion. At $2,000 billion nominal GDP, debt/GDP is 55%. Actual debt changes can also reflect cash-balance movements and other financing transactions.^[1][3]

Under current law, this combination does more than stabilize the ratio. Brookings puts the permanent adjustment needed to hold debt/GDP at 99% in 2056 at about $707 billion a year in today's economy, below the $800-1,000 billion total above.^[9] The cushion depends on the baseline. Make temporary tax provisions, such as those in the 2025 One Big Beautiful Bill Act, permanent and set discretionary spending at levels that maintain government services, and Brookings projects debt at 211% of GDP in 2056 instead of 175%. That baseline, or a later start, raises the adjustment required.^[9]

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 ↗ Source 12 in the list belowCRS 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.

The historical record

The debt ceiling has been raised, suspended, or modified more than 100 times since 1917. It has never 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 ↗ Source 13 in the list belowFitch 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.

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) ↗ Source 6 in the list belowEmpirical 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 ↗ Source 14 in the list belowNet interest more than doubled 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 (~$1.13T); 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.

Keep the net-outlay figures straight. CBO’s February 2026 report puts FY2025 net interest at $970 billion, not above $1 trillion; over $1 trillion is the FY2026 projection. Gross interest on Treasury securities is a different statistic, and it does not relabel net budget outlays.^[1]

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 $1.13 trillion.

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) ↗ Source 15 in the list belowFerguson 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 interest trap

Higher rates restrain demand and raise financing costs as debt is issued or refinanced. How much and how fast depends on maturities, coupons, inflation-indexed securities and market yields, not just the overnight policy rate.^[1]

Run the sensitivity yourself: $100 billion of debt refinancing 1 percentage point higher costs $1 billion more a year, all else equal. Existing fixed-rate debt does not reprice at once, and average maturity is not the date the whole stock matures. Use the actual maturity schedule, and keep gross debt separate from debt held by the public.^[1]

Fiscal dominance, plainly

Fiscal dominance is a conditional risk: financing needs constrain monetary policy when budget adjustment and monetary independence both fail. A large debt stock on its own does not prove that regime is here or that the Fed cannot raise rates.^[1][18] The mechanism, its history and its warning markers are covered in Fiscal Dominance: When Debt Runs Policy.

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) ↗ Source 19 in the list belowTheir 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.

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.

Bitcoin's relevance to the debt picture

Bitcoin's 21 million cap cannot be debased to service government debt. No politician can vote to issue more bitcoin. No central bank can print bitcoin to absorb a Treasury auction. The asset is structurally outside the fiscal-monetary loop that produces debt-driven inflation.

That property is not a marketing claim - it is the entire design. The Bitcoin whitepaper was published in October 2008, in the middle of the global financial crisis.^[21] The genesis blockgenesis blockThe very first batch of Bitcoin transactions, created by Bitcoin's anonymous inventor Satoshi Nakamoto on January 3, 2009. Every Bitcoin transaction since then traces back to it.Full definition in January 2009 included a newspaper headline about UK bank bailouts. The system was built specifically as an opt-out from the monetary mechanism that produces debt crises like the one above.

For an individual saver, the practical question is what fraction of long-term wealth is held in dollar-denominated assets that get repriced if the dollar loses real value, and what fraction is held in assets that cannot be repriced by policy. See Monetary Premium for the deeper case.
