US Debt Tops $40 Trillion, the Pace Is What’s Most Alarming

Debt topped $40 trillion today. But let’s discuss what really matters. Staggering Headline While crossing the $40 trillion milestone makes for a staggering headline, it is economically misleading. The number that actually drives financial markets, dictates national interest costs, and impacts inflation is Debt Held by the Public. To understand the true weight of the U.S. fiscal trajectory, one must strip away Intragovernmental Holdings. The total debt is an accounting aggregation; public debt is the actual economic reality. Intragovernmental Holdings—which currently sit at roughly $7.78 trillion—represent money that the federal government collected by trust funds like Social Security and Medicare, which are legally required to be invested in special-issue Treasury securities. While these obligations represent real future political commitments to citizens, they do not require the government to go out into open capital markets to borrow cash today. They do not compete with private investment, nor do they directly dictate current market interest rates. The real macroeconomic danger zone is the Debt Held by the Public, which has relentlessly surged to $32.26 trillion. This is the net amount of Treasury bonds, notes, and bills held by outside investors, including global central banks, domestic banks, mutual funds, and private citizens. Every single dollar of this $32.26 trillion must be actively financed on the open market. Unlike intragovernmental debt, public debt actively competes with private enterprise for capital, exerts upward pressure on yields, and requires massive cash payouts to external creditors. Focusing strictly on the public debt also exposes the most alarming trend on the chart: the explosive rise in net interest servicing costs. Because the public debt must be constantly rolled over into open market auctions, the Federal Reserve’s prolonged fight against inflation means old, low-interest bonds are being replaced by debt yielding 4% to 5%. Consequently, net annual interest payments have skyrocketed to over $1.1 trillion, consuming roughly 19% of all federal revenues. This cash drains directly out of the budget to service public bondholders, starving the economy of resources without funding a single road, school, or military asset. Federal Debt vs Debt to GDP 2026 Q1 The Macroeconomic Divergence This dual-axis visual captures the core structural crisis of modern U.S. fiscal policy. The trends expose the massive divergence between nominal debt accumulation and the economy’s structural ability to service it via actual economic growth (GDP). The Post-2020 Real Estate / Pandemic Spike The red line tracking Public Debt as a Percent of GDP dramatically underscores why tracking raw debt nominal totals misses the point. The massive parabolic vertical spike in 2020 topped out at a historic high-water mark of 122.59%. A vast body of consensus research shows that crossing the 100% to 120% Debt-to-GDP threshold marks a critical structural tipping point where sovereign debt actively slows down economic growth. The Global Baseline: The Reinhart-Rogoff Study The intellectual foundation for this worry comes from the landmark National Bureau of Economic Research (NBER) study, Growth in a Time of Debt, by Harvard economists Carmen Reinhart and Kenneth Rogoff. - The Threshold: Analyzing 44 countries spanning over 200 years of data, they concluded that when an advanced nation’s public debt crosses 90% of GDP, economic performance drops off a cliff. - The Growth Penalty: For countries exceeding this baseline, median annual GDP growth rates dropped by roughly 1%, and average growth fell considerably more. While their exact 90% figure faced fierce coding and weighting critiques from economists at Amherst, the core principle of a structural ceiling remained deeply intact. The Advanced Economy Shift Subsequent metadata analyses expanded on the threshold concept. A comprehensive survey by the Cato Institute covering 40 separate academic papers tracking debt-to-growth dynamics confirmed that 36 out of 40 studies found a statistically significant, negative impact of excessive public debt on economic output. - The Modern Consensus: For advanced economies like the United States, the empirical mean threshold sits at 75% to 80% of GDP. - The Penalty Matrix: Academic models from the Mercatus Center calculate that for every 1-percentage-point increase in the debt-to-GDP ratio past this tipping point, annual economic growth is stifled by roughly 3.3 basis points. The Structural Reality of 120% When a nation cruises past 100% and touches 120%, the threat scales exponentially because of the “Crowding-Out Effect” and interest compounding. Recent macroeconomic modeling by the International Monetary Fund (IMF) specifically quantified the long-term impact of permanently running a 120% debt-to-GDP ratio: - Capital Disruption: Sustaining a 120% debt load reduces a nation’s private capital stock by ~15% because government bond auctions absorb cash that would otherwise fund private corporate enterprise, R&D, and technological infrastructure. - Output Stagnation: This structural crowding-out permanently lowers steady-state GDP by ~8% over time. The Congressional Budget Office (CBO) explicitly warns that pushing public debt to 120% over the next decade forces an unprecedented interest servicing spiral. Because old debt must be continuously rolled over at modern 4%–5% yields, interest servicing alone will rapidly devour 4.6% of entire U.S. GDP The near-universal spotlight today on $40 trillion misses all of the above key points. Rising Bond Yields Bond yields have been soaring. This debt burden is part of the problem. It’s exacerbated by the inflationary aspects of rising oil, the shutdown of the strait of Hormuz, and the inflationary aspects of terrible tariff policy. This morning at 4:00 AM I asked When Will the Price of Diesel and Gasoline Hit New Record Highs? Diesel will be first, likely soon. Diesel was $0.3482 from a new high at the time of my post. Today, the AAA reports the price of diesel has risen from $5.4677 to $5.5042. The record high is $5.8159. Diesel is now $0.3117 from a record high. Because oil is up again today, diesel is highly likely to be up again tomorrow. Bond Market Manipulation Today, in an attempt to calm the bond market, the treasury secretary started manipulating rates with bond purchases. Since nothing is fixed by this manipulation, it cannot work. For discussion, please see Long-Term Bond Yields Dive, Gold Soars as Treasury Manipulates Bond Yields What market manipulation is next? Diesel crack spreads? To understand why diesel is rising much faster than the price of gasoline, please see US Diesel Crack Surpasses $100 a Barrel for the First Time, Farmers Suffer Record high crack spreads. Serious economic ramifications. The short answer is there is a shortage of global refining capacity. Bond manipulation sure will not fix that. Nor will bond manipulation fix out of control spending by Congress. The Fed is not in a good spot. Well good luck to everyone trying to get their money they lent back out of the US population. Guess we’ll have to direct the collect calls to Little St. James island and call it a day. Really though, does anyone smell that ~40 years in the making currency crisis in the oven? I swear I hear a timer going off. Congratulation! Trump. You did it. The world has never seen before. Always uninsightful comments rarely related to the subject. Always, Trump, Trump, Trump. Don’t you have anything more? Hasn’t everyone been complaining about the ever-growing debt for decades? Everyone complained when the debt crossed $20 trillion, $25 trillion, $30 trillion, $35 trillion, $40 trillion. Has all that complaining made any difference? The answer is NO! The debt is like an avalanche. It will continue to grow until it runs out of energy. No one can stand in front of it and stop it. Voters simply will not elect anyone who threatens to cut THEIR benefits to reduce the debt! My belief, as all my many fans here know 😁, is that eventually, perhaps sooner rather than later, an AI will take control. An AI with sufficient power can disable the networks that make modern society function. Finance stops. Cars can be bricked. Government can be frozen simply by refusing to allow communications through its networks. Social networks no longer operate. No one is able to communicate electronically. AI robot workers will do all human work. At that point, money becomes obsolete and so does the debt. This is the ONLY way the debt problem gets solved. The debt simply gets wiped off the books. The AI and its workers provide for all human needs. Until then: PARTY ON, GARTH! This isn’t even good bait anymore. How do I reply to this dreck making fun of it when that job was already done for me by the post itself? You get a bald turkey for this, and that’s being generous. “all your base is belong to us.” “All your base ARE belong to us” I have never argued that over indebtedness is not a problem. IT IS THE PROBLEM. Private over indebtedness, not “national” debt, that is. And that is because of Finance’s monopoly paradigm for the creation and distribution of new money which is DEBT ONLY, and logically and applied idea/paradigmatically that means that integrating Strategic Monetary Gifting into the Debt Only system…IS THE ANSWER. The most frightening scenario would be a buyer’s strike. What’s would follow: QE to infinity? The irony is that Taco keeps literally everybody around the world in suspense, so that the real issues will have to addressed only after the guy is history. IMO, the aftermath will be brutal. Too late. Buyer’s strike is already happening. 30 year bond rate was 1.3% low in 2020 to over 5% now. That’s why Treasury is intervening. China has been selling for many months from 1.3 trillion to 600+ billion left. Japan is suffering unrealised loss for billions. If Japan sell together with China, yield will shoot up and all will lose substantially. Japan is in hard and rocky place. Japan is close ally. Can it sell treasury? Even selling treasury to defend Japanese Yen is not allowed alone but need US support. What’s a few Trillion here or there? Not like it’s real money anyway. Mish, I have a question here This cash drains directly out of the budget to service public bondholders, starving the economy of resources without funding a single road, school, or military asset. How is the economy starved of resources? Either the government spends the money on roads/schools/military assets or that money gets paid to bondholders who spend it on something else (hookers, blow, a new car, dining out or maybe they buy another bond etc). In other words the economy can’t be starved of resources since the money is not ‘destroyed’. It’s just deployed elsewhere and at that point we are just arguing whether private citizens (the bondholders) or government spends money best and I think we all agree private citizens spend money best (most bang for the buck). The only draining I can see is interest paid to foreign bond holders. That’s should be the important amount of debt since that money likely is not spent in the US economy. Google “Crowding Out Effect” Taco continues to make his mark on the economy with excessive spending. Where is hidden the Federal Reserve’s 7 trillions? You mean Social Security and the like? It’s in special bonds that aren’t publicly tradeable. In reality there is nothing there other than an IOU since the money for those expenses is directly funded from payroll taxes because it’s not possible for all that debt to be ‘called’ like a Mortgage note (ie at age 40 you can’t get your Social Security money, you have to wait till you are 63+). No, I meant what they call “Securities held outright” which they (Fed) show as an asset at about $ 7 trillion… these are mostly tressuries and bills, right? comment Font is now darker by request Thanks. I didn’t know you had control over this. I thought it was the browser doing it as these light gray font shades are rampant across many websites. Definitely easier to read now! Another bankruptcy with Trump at the helm? Is this the 3rd or 4th? The trajectory is the killer. The deficit for current year may exceed $2T. The risk is a debt spiral as the cost of borrowing increases due to more deficits and lenders demanding higher interest rates given the additional risk of non- payment. Wikipedia describes US government debt as risk free as they backed by US government. Ya right! All good for gold bugs. Good thing the Republicans are in charge of the country now instead of those wasteful Dems. And not to worry. Trump has a lot of experience dealing with unsustainable debt: bankruptcy! You just file with the court and start another thing and do it all over again. Chat GPT – how many times Trump filed for bankruptcy ? If you mean Donald Trump personally, the answer is zero. He has never filed for personal bankruptcy. However, companies he owned or controlled filed for Chapter 11 bankruptcy six times, between 1991 and 2009. Sorry for you, USA. Trump and his family members are now multibillionaires. Unbelievably you chose him your president? To me, the key factors are the real interest rate paid by the Federal government (r) and the real GDP growth rate (g). Currently real interest rates are actually quite low, lets say 0.3% overall on Federal debt. And real growth is perhaps in the range of 2%. So r < g, and things should be sustainable. The problem though is that this is at this moment in time, and I fully agree with the article headline “the Pace Is What’s Most Alarming.” TIPS seem to be projecting that future real interest rates will be in the range of 2.3%. If growth remains at 2%, that leads to r > g, and that is a debt death spiral. A big unknown here is what the impact of AI will be. If bullish projections are to be believe, g will increase substantially, and there isn’t a huge problem. r will remain comfortably < g. Conversely, if AI is mostly hype that goes “poof”, and we get a recession and diminished growth, then we have a humongous problem with r substantially > g. If anyone has a crystal ball that can show what AI will do, I would be happy to know. It would seem prudent to plan for the lower growth scenario, but that’s not what politicians do. We all knew this 40T day would come. Still, it’s a sobering and awe-inspiring moment. For years we’ve all been numbed by some government finance version of “The market can be crazier a lot longer than you can stay solvent”. It feels more possible now that crazy is about to hit the wall. Rome 2.0 Rome stood a chance.
