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
The Congressional Budget Office publishes the authoritative federal fiscal projections twice a year. The current Budget and Economic Outlook (February 2026) is the source for every figure below verify×DON'T TRUST, VERIFYClaim: All numbers in this section come from CBO February 2026 Budget and Economic Outlook.Verify at: cbo.gov/publication/budget-economic-outlook ↗CBO updates the outlook every February and August. Always link to the most recent..
Net interest payments already exceed total defense spending verify×DON'T TRUST, VERIFYClaim: Federal net interest now exceeds defense spending.Verify at: CBO Monthly Budget Review ↗ · Peterson Foundation tracker ↗Crossover happened in 2024. Interest is now the third-largest budget category after Social Security and health programs.. By approximately 2038, interest alone is projected to exceed total discretionary spending: defense plus every other non-mandatory program combined.
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. InflationinflationA general increase in prices over time, meaning each dollar buys less than it did before.Full definition 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 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). 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.
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 in the modern era. The case for holding scarce assets follows from the math, not from a forecast.
