Has America’s Exploding Federal Debt Actually Crowded Out Private Wealth?

We hear constantly that America’s growing federal debt is going to impoverish the country.

One of the traditional economic arguments is “crowding out.”

The basic idea makes intuitive sense: the federal government borrows enormous amounts of money, competes with the private sector for capital, potentially pushes interest rates higher, and leaves less capital available for productive private investment.

But that got me wondering:

If federal debt has exploded over the past 65 years, what has actually happened to American household wealth?

So I started looking at the numbers.

And they weren’t quite what I expected.

Start With Household Assets vs. GDP

The first thing I looked at was total assets held by U.S. households and nonprofit organizations relative to GDP.

According to the Federal Reserve’s Financial Accounts data, household and nonprofit assets were roughly:

• 427% of GDP in 1960
• 406% in 1970
• 413% in 1980
• 442% in 1990
• 506% in 2000
• 532% in 2010
• 691% in 2020
• 664% in 2025

That’s an enormous stock of assets.

And despite all the claims that America has somehow been hollowed out financially, household assets relative to the size of the economy are considerably higher today than they were in 1960.

Then I compared that with federal debt held by the public as a percentage of GDP.

That produced an interesting picture.

Both household assets/GDP and public debt/GDP have generally risen over the long run.

And statistically, the correlation between the two levels was very high—roughly +0.85.

At first glance, you might look at that and conclude:

More government debt = more household wealth.

Not so fast.

The Correlation Problem

There’s an important statistical issue here.

We’re comparing two series that have both generally trended upward for decades.

And they share the exact same denominator:

GDP

Suppose GDP falls during a recession.

Even without large changes in debt or household assets, both debt/GDP and assets/GDP can rise simply because the denominator fell.

So a high correlation between the two ratios doesn’t necessarily tell us that increases in federal debt are causing increases in household wealth.

We needed a tougher test.

What Happens When Federal Debt Actually Increases?

Instead of comparing the levels, I compared the annual change in public debt/GDP with the annual change in household assets/GDP.

The correlation collapsed.

It was only about:

+0.31.

That’s dramatically lower than +0.85.

Then I wondered whether perhaps there was a lag.

Maybe government borrowing doesn’t immediately show up in asset values.

So what if debt increases today and household wealth increases one, two or three years later?

We tested that too.

And there still wasn’t a particularly strong relationship.

That led to another question.

Maybe GDP was muddying the waters.

So let’s get GDP completely out of the calculation.

Forget GDP—Let’s Look at Actual Dollars

Next, I compared the percentage growth in the actual dollar amount of federal debt held by the public with subsequent percentage growth in actual household assets.

Here’s what we found:

That’s not particularly compelling.

The strongest positive relationship was just +0.194 one year later.

At two years, the correlation was essentially zero.

So the idea that rapid growth in federal debt mechanically produces rapid growth in household assets a couple of years later wasn’t supported by this simple historical test.

What About Federal Deficits?

Then I tried something that gets even closer to the underlying economic argument.

Instead of looking at the accumulated federal debt, I looked at the annual federal deficit as a percentage of GDP.

The question became:

When Washington runs an unusually large deficit, do household assets subsequently grow unusually fast?

Again, the answer was basically no.

The correlations looked like this:

In other words, knowing the size of this year’s federal deficit historically hasn’t told us much about household asset growth over the next several years.

Then I Looked at the Raw Numbers

This is where I think things get especially interesting.

Instead of percentages or correlations, let’s simply compare the amount of household assets with federal debt held by the public.

In nominal dollars:

There’s something important happening here.

Household assets are still vastly larger than federal debt.

But federal debt has clearly been gaining ground.

In 2000, household assets were roughly 15 times federal debt held by the public.

Today they’re closer to seven times.

That’s a deterioration worth paying attention to.

But nominal dollars over 65 years can also be misleading because of inflation.

So I adjusted everything to constant 1980 dollars.

Now Adjust Everything for Inflation

This may be my favorite comparison.

In 1980 dollars:

Now we can see what’s actually happened to purchasing-power-adjusted wealth.

From 1960 through 2025:

Real household assets increased from approximately $6.5 trillion to more than $52 trillion in 1980 dollars.

That’s more than an eightfold increase.

Meanwhile, real federal debt held by the public increased from roughly $660 billion to $7.7 trillion.

So yes, federal debt grew faster.

But America didn’t become poorer in terms of household asset wealth.

Quite the opposite.

And Look at What Happened Since 2000

This period is particularly revealing because federal borrowing accelerated dramatically.

In 2000:

Real household assets: $24.8T

Real federal debt: $1.6T

By 2025:

Real household assets: $52.3T

Real federal debt: $7.7T

So federal debt increased roughly 4.7 times in real terms.

That’s huge.

But household assets still more than doubled in real terms.

That doesn’t look like an economy where the private asset base simply got squeezed out of existence by government borrowing.

So Does This Disprove “Crowding Out”?

No.

And this distinction matters.

The traditional crowding-out argument doesn’t necessarily say:

Government debt rises, therefore household wealth must fall.

The more sophisticated argument is that government borrowing can compete for capital, increase real interest rates and cause private investment to be lower than it otherwise would have been.

Those last words are critical:

“Than it otherwise would have been.”

That’s a counterfactual.

Maybe household assets reached $52 trillion in constant 1980 dollars despite the debt.

But perhaps without so much federal borrowing they would have reached $60 trillion.

Or $70 trillion.

Our charts can’t answer that question.

There’s another complication too.

Treasury securities themselves are financial assets to whoever owns them.

The federal government’s liability is somebody else’s asset.

So we shouldn’t look at $52 trillion of household assets and $7.7 trillion of federal debt and conclude:

“No problem! We can just use the household assets to pay off the debt.”

Absolutely not.

Those household assets belong to households and nonprofits—not the federal government.

And some federal debt is itself contained within private-sector financial assets.

But We Can Say Something Important

What I think the historical evidence does challenge is the simplistic version of the story:

Massive government borrowing inevitably destroys private wealth.

That simply isn’t what happened.

The federal debt exploded.

And at the same time, real household asset wealth exploded too.

In fact, real household assets today are more than eight times their 1960 level.

The better concern isn’t that household wealth disappeared.

It’s that federal debt has been growing faster than household assets, particularly since 2000.

That’s why the household-assets-to-federal-debt ratio fell from about:

15.2× in 2000

to

6.8× in 2025.

That’s a very different argument from saying America is broke.

What I’d Test Next

If we really want to test the traditional crowding-out hypothesis, household wealth probably isn’t the best variable.

We should look directly at productive private investment.

Specifically:

Federal debt/GDP versus private nonresidential fixed investment/GDP from 1960 through 2025.

Why?

Because that’s much closer to what the crowding-out theory actually predicts.

If enormous federal borrowing consistently displaced private capital formation, we should see evidence of it in private investment.

We could also examine federal borrowing against real interest rates, corporate investment, capital formation and productivity growth.

Those tests would get much closer to answering the actual economic question.

The Bottom Line

America absolutely has a federal debt problem worth discussing.

Federal debt has grown much faster than household assets since 2000.

But there’s a huge difference between saying:

“Federal debt is growing too quickly.”

and saying:

“Federal debt has impoverished the American private sector.”

The data we’ve examined don’t support that second statement.

Despite decades of increasing federal debt—and an extraordinary acceleration since 2000—Americans collectively hold far more real assets today than they did in 1960, 1980 or 2000.

The asset-to-debt ratio has deteriorated.

But the real private asset base hasn’t disappeared.

It has grown enormously.

And that distinction matters.

Data note: Household asset figures refer to the Federal Reserve’s “Households and Nonprofit Organizations; Total Assets” series, so they include nonprofit organizations. Federal debt refers to federal debt held by the public rather than gross federal debt. Inflation-adjusted calculations use CPI to express nominal values in constant 1980 dollars. These comparisons describe historical relationships and do not by themselves establish causation.
