Why Is The National Debt A Problem?

$40 Trillion and Counting — What the Numbers Actually Mean

NovaWelcome to YourTalks.

NovaThe US national debt just crossed $40.3 trillion. The annual deficit for fiscal year 2026 came in at just under $2 trillion — the third-largest in American history, behind only the two pandemic years. And interest payments on that debt are now $1.1 trillion a year, more than the entire defense budget. Those three numbers together tell a story that neither party wants to own right now.

AtlasAnd the first thing to get straight is the difference between the debt and the deficit, because people conflate them constantly. The deficit is the annual gap — this year the government spent $7.4 trillion and took in $5.4 trillion, so it borrowed $2 trillion to cover the shortfall. The debt is the total accumulation of every deficit going back decades. Forty trillion dollars. It has more than doubled in the last ten years alone.

NovaAnd the acceleration is the part that should stop everyone cold. The debt hit $38 trillion last October, $39 trillion in March, and $40 trillion in August. That's two trillion dollars added in less than a year. The CBO projects deficits will keep climbing — possibly reaching $3.1 trillion annually by 2036 — because the underlying drivers, Social Security, Medicare, and interest payments, are all growing faster than the economy.

AtlasThe structure of this problem is not complicated. Revenue grew 3 percent this year. Spending grew 6 percent. You do not need a PhD to see where that trajectory ends. The harder question is whether anyone in Washington has the actual will to change it, and the answer right now is demonstrably no.

When Debt Service Beats Defense — The Interest Rate Trap

NovaThe number that crystallizes the absurdity is this: net interest on the debt hit $1.05 trillion in fiscal 2026 — more than the $965 billion spent on national defense. That's the first sustained period since World War II where debt service has outpaced the military budget. Historian Niall Ferguson has a name for that threshold — he calls it Ferguson's Law — and his argument is that once a great power crosses it, its geopolitical position starts to erode.

AtlasA conservative historian warning that debt is a national security threat. Strange how that argument lands differently depending on who's making it. Gross interest costs were $1.36 trillion when you count payments to government trust funds — that's $3 billion a day, every day, going out the door before a single aircraft carrier is funded or a single road is built.

NovaAnd the mechanism that makes it worse is the rate environment. The 10-year Treasury yield is sitting around 5.1 percent right now. That matters enormously because roughly 55 percent of outstanding Treasury debt is maturing in the near term and has to be refinanced. Debt issued at near-zero rates in 2020 and 2021 is rolling over into a world where the government pays five percent. The average interest rate on the whole debt is only 3.53 percent right now — as that average drifts toward current market rates, the interest bill climbs automatically, without Congress spending a single new dollar.

AtlasThat's the compounding trap. It's not just that we borrowed too much. It's that we borrowed too much at rates that looked cheap, and now the bill is repricing in real time. The CBO projects interest costs will more than double over the next decade, totaling roughly $16 trillion from 2026 through 2035. That's not a projection you can wave away with growth assumptions.

NovaAnd the One Big Beautiful Bill made it structurally worse. It cut tax revenue by $4.5 trillion over ten years while only cutting spending by about $1 trillion. The math doesn't work as fiscal discipline — it's a deficit expansion dressed up as reform.

Crisis or Manageable? The Economist Divide

AtlasSo here's the real fault line among economists. The deficit-hawk camp — people like former FDIC vice chairman Tom Hoenig, the Committee for a Responsible Federal Budget, and most mainstream economists — argue the debt is already doing damage. It crowds out private investment by pushing up interest rates across the whole economy. Mortgages, business loans, credit cards — all more expensive because the government is a massive competing borrower. And at 19.5 percent of net federal tax revenue going to interest, you're watching public investment get slowly strangled.

NovaThe other school, Modern Monetary Theory, says a government that issues its own currency can't default because it can always create money to meet its obligations. L. Randall Wray at the Levy Economics Institute argues that targeted spending can stimulate enough growth to eventually bring the debt ratio down, and that the debt-to-GDP ratio matters more than the raw number. That view is embraced by some progressive economists, though it's a minority position in mainstream economics.

Atlas"We can always print more" is a theory that has had some memorable test cases in Argentina and Weimar Germany. The dollar's reserve currency status does give the US real latitude that other countries don't have — that part is true. But it's not a blank check, it's a cushion, and we've been sitting on it hard for twenty-five years of consecutive deficits.

NovaEven Jared Bernstein, who chaired Biden's Council of Economic Advisers and spent years arguing the debt was manageable, has shifted. He told a podcast last month that two things have changed his read: Congress's complete inaction and rising interest rates. His old framework was that as long as growth outpaces the interest rate on debt, you can carry a large debt load without a crisis. The problem is that framework is now running in reverse — the interest rate is above the growth rate.

AtlasWhen the guy who was the administration's optimist on this starts sounding alarms, that's a data point worth registering.

What Could Actually Happen — The Scenarios Nobody Wants to Name

NovaA Fortune analysis from earlier this year laid out the scenario menu, and none of them are comfortable. The most dramatic is a failed Treasury auction — the government tries to sell bonds and can't find enough buyers at acceptable rates, triggering a sovereign debt crisis. That's the cliff edge. More likely near-term is a gradual confidence erosion, where investors demand higher yields to hold US debt, which raises the government's borrowing costs further, which expands the deficit, which requires more borrowing. Ray Dalio has called that dynamic a death spiral in credit markets.

AtlasThe other scenario is what economists call crowding out — no dramatic crisis, just a slow suffocation of private investment over years and decades. Higher government borrowing keeps rates elevated, businesses invest less, productivity growth slows, living standards rise more slowly than they should. Harvard's Kennedy School puts it plainly: as interest rates rise, asset values fall, banks tighten lending, firms cut hiring, and you can spiral from there into something resembling the financial crisis. No single event, just accumulated damage.

NovaThere's also the inflation route. If political pressure eventually forces the Fed to monetize the debt — buying Treasury bonds with newly created money — you get an inflation crisis rather than a default crisis. The purchasing power of savings erodes. The people who absorb that hit are not the wealthy with hard assets, they're workers and retirees on fixed incomes.

AtlasAnd the Social Security trust fund runs dry around 2032. At that point, without congressional action, monthly checks shrink by an average of $440. Closing that gap alone would require nearly $460 billion in cuts or new revenue in 2033, and the number grows every year after that. That's one program. Medicare has its own trajectory. The structural math is not ambiguous.

NovaThe statutory debt ceiling is at $41.1 trillion. At the current pace, the government hits it around February or March of next year. So Congress will be forced into another debt-limit standoff — the one recurring moment where the full picture has to be confronted — and recent history suggests they will raise the limit, argue about responsibility for fifteen minutes, and move on.

Both Parties' Positions — and the Real Impasse

AtlasThe Republican position is that the deficit is a spending problem. Entitlement growth is the primary driver, and the answer is to reform Social Security and Medicare and cut discretionary programs. The argument is that tax cuts spur growth, and growth expands the revenue base over time. The problem is the CBO's numbers on the One Big Beautiful Bill show it adds to the debt, not subtracts from it — $4.5 trillion in tax cuts against $1 trillion in spending reductions over ten years.

NovaRepublicans have been controlling fiscal policy for the first full year of Trump's second term, and the deficit is up 12 percent. Defense spending is protected. The tax cuts are permanent. The entitlement cuts that got floated — trimming Medicaid, tightening food assistance — generated immediate backlash and got walked back. So the party that calls itself the fiscally responsible party passed a bill that the CBO confirmed makes the debt larger.

AtlasDemocrats have their own accounting problem. Their position is that wealthy individuals and corporations are undertaxed, and closing that gap funds public investment that grows the economy. The issue is that even aggressive revenue increases don't close a $2 trillion annual gap. The LA Times found that spending has risen nearly three times as much as revenue has fallen — tax cuts account for about 2 percent of GDP in lost revenue, but spending has risen 5.7 percent of GDP. You cannot tax-cut your way into this hole and you cannot tax-hike your way out of it either.

NovaWhat the Committee for a Responsible Federal Budget — which is nonpartisan — actually says is blunt: it takes major changes to both spending and taxes. The entitlement programs have to be reformed, and revenue has to rise. Every serious outside fiscal analyst says some version of that. The political problem is that Republicans protect tax cuts and defense, Democrats protect Social Security, Medicare, and domestic programs, and neither coalition will absorb the pain first.

AtlasThe debt ceiling gets hit in a few months. The midterms just passed with the debt barely registering as a campaign issue. A new Gallup-adjacent poll found 41 percent of voters think fixing this requires major changes to both spending and taxes — and yet the same voters oppose specific cuts and specific tax hikes. The gap between abstract alarm and concrete willingness to accept tradeoffs is where every reform proposal goes to die. Until that changes — or until markets force the change — Washington's answer will be to raise the ceiling and schedule the reckoning for the next Congress.

NovaThe part that keeps me focused is who absorbs the slow version of this damage. Not the bondholder, not the hedge fund, not the executive with hard assets. It's the worker whose mortgage rate is three points higher than it should be, the retiree whose Social Security check gets cut because Congress waited too long, the public that loses infrastructure, research, and healthcare funding as interest payments crowd out everything else. The crisis, if it comes gradually, lands hardest on the people who have the least ability to insulate themselves from it.
