Public Debt and AI: Ain’t But One Way Crowding Out

There’s a hopeful narrative making the rounds that artificial intelligence will prove to be such a boon to the economy that we need not worry about high levels of government debt. AI investment is already having a substantial economic impact. Jason Thomas of Carlyle says that AI capital expenditures on such things as data centers, hardware, and supporting infrastructure account for about a third of second quarter GDP growth (preliminarily a 3% annual rate). Furthermore, he says relevant orders are growing at an annual rate of about 40%. The capex boom may continue for a number of years before leveling off. In the meantime, we’ll begin to see whether AI is capable of boosting productivity more broadly.

Unfortunately, even with this kind of investment stimulus, there’s no assurance that AI will create adequate economic growth and tax revenue to end federal deficits, let alone pay down the $37 trillion public debt. That thinking puts too much faith in a technology that is unproven as a long-term economic engine. It would also be a naive attitude toward managing debt that now carries an annual interest cost of almost $1 trillion, accounting for about half of the federal budget deficit.

Boom Times?

Predictions of AI’s long-term macro impact are all over the map. Goldman Sachs estimates a boost in global GDP of 7% over 10 years, which is not exactly aggressive. Daren Acemoglu has been even more conservative, estimating a gain of 0.7% in total factor productivity over 10 years. Tyler Cowen has been skeptical about the impact of AI on economic growth. For an even more pessimistic take see these comments.

In July, however, Seth Benzell of the Stanford Digital Economy Lab discussed some simulations showing impressive AI-induced growth (see chart at top). The simulations project additional U.S. GDP growth of between 1% – 3% annually over the next 75 years! The largest boost in growth occurs now through the 2050s. This would produce a major advance in living standards. It would also eliminate the federal deficit and cure our massive entitlement insolvency, but the result comes with heavy qualifications. In fact, Benzell ultimately throws cold water on the notion that AI growth will be strong enough to reduce or even stabilize the public debt to GDP ratio.

The Scarcity Spoiler

The big hitch has to do with the scarcity of capital, which I’ve described as an impediment to widespread AI application. Competition for capital will drive interest rates up (3% – 4%, according to Benzell’s model). Ongoing needs for federal financing intensify that effect. But it might not be so bad, according to Benzell, if climbing rates are accompanied by heightened productivity powered by AI. Then, tax receipts just might keep-up with or exceed the explosion in the government’s interest obligations.

A further complication cited by Benzell lurks in insatiable demands for public spending, and politicians who simply can’t resist the temptation to buy votes via public largesse. Indeed, as we’ve already seen, government will try to get in on the AI action, channeling taxpayer funds into projects deemed to be in the public interest. And if there are segments of the work force whose jobs are eliminated by AI, there will be pressure for public support. So even if AI succeeds in generating large gains in productivity and tax revenue, there’s very little chance we’ll see a contagion of fiscal discipline in Washington DC. This will put more upward pressure on interest rates, giving rise to the typical crowding out phenomenon, curtailing private investment in AI.

Playing Catch-Up

The capex boom must precede much of the hoped-for growth in productivity from AI. Financing comes first, which means that rates are likely to rise sooner than productivity gains can be expected. And again, competition from government borrowing will crowd out some private AI investment, slowing potential AI-induced increases in tax revenue.

There’s no chance of the converse: that AI investment will crowd out government borrowing! That kind of responsiveness is not what we typically see from politicians. It’s more likely that ballooning interest costs and deficits generally will provoke even more undesirable policy moves, such as money printing or rate ceilings.

The upshot is that higher interest rates will cause deficits to balloon before tax receipts can catch up. And as for tax receipts, the intangibility of AI will create opportunities for tax flight to more favorable jurisdictions, a point well understood by Benzell. As attorneys Bradford S. Cohen and Megan Jones put it:

“Digital assets can be harder to find and more easily shifted offshore, limiting the tax reach of the U.S. government.”

AI Growth Realism

Benzell’s trepidation about our future fiscal imbalances is well founded. However, I also think Benzell’s modeled results, which represent a starting point in his analysis of AI and the public debt, are too optimistic an assessment of AI’s potential to boost growth. As he says himself,

“… many of the benefits from AI may come in the form of intangible improvements in digital consumption goods. … This might be real growth, that really raises welfare, but will be hard to tax or even measure.”

This is unlikely to register as an enhancement to productivity. Yet Benzell somehow buys into the argument that AI will lead to high levels of unemployment. That’s one of his reasons for expecting higher deficits.

My view is that AI will displace workers in some occupations, but it is unlikely to put large numbers of humans permanently out of work and into state support. That’s because the opportunity cost of many AI applications is and will remain quite high. It will have to compete for financing not only with government and more traditional capex projects, but with various forms of itself. This will limit both the growth we are likely to reap from AI and losses of human jobs.

Sovereign Wealth Fund

I have one other bone to pick with Benzell’s post. That’s in regard to his eagerness to see the government create a sovereign wealth fund. Here is his concluding paragraph:

“Instead of contemplating a larger debt, we should instead be talking about a national sovereign wealth fund, that could ‘own the robots on behalf of the people’. This would both boost output and welfare, and put the welfare system on an indefinitely sustainable path.”

Whether the government sells federal assets or collects booty from other kinds of “deals”, the very idea of accumulating risk assets in a sovereign wealth fund undermines the objective to reduce debt. It will be a struggle for a sovereign wealth fund to consistently earn cash returns to compensate for interest costs and pay down the debt. This is especially unwise given the risk of rising rates. Furthermore, government interests in otherwise private concerns will bring cronyism, displacement of market forces by central planning, and a politicization of economic affairs. Just pay off the debt with whatever receipts become available. This will free up savings for investment in AI capital and hasten the hoped-for boom in productivity.

Summary

AI’s contribution to economic growth probably will be inadequate and come too late to end government budget deficits and reduce our burgeoning public debt. To think otherwise seems far fetched in light of our historical inability to restrain the growth of federal spending. Interest on the federal debt already accounts for about half of the annual budget deficit. Refinancing the existing public debt will entail much higher costs if AI capex continues to grow aggressively, pushing interest rates higher. These dynamics make it pretty clear that AI won’t provide an easy fix for federal deficits and debt. In fact, ongoing federal borrowing needs will sop up savings needed for AI development and diffusion, even as the capital needed for AI drives up the cost of funds to the government. It’s a shame that AI won’t be able to crowd out government.

June Budget Surplus and Wishful Tariff Thinking

21 Monday Jul 2025

The federal government ran a budget surplus of $27 billion in June, much to the surprise of nearly everyone. The Trump Administration and MAGA-friendly media were eager to credit a big revenue boost from higher tariffs, which… ahem … they have assured us are not really taxes. In any case, to attribute the June surplus to tariffs is flatly ridiculous. The truth is these “non-tax” magic revenue generators made a relatively small contribution to the apparent shift in the government’s fiscal position in June. And I say “apparent” because the surplus itself was something of a mirage.

Yes, tariffs brought in a total of almost $27B during June, which is about the same as the surplus recorded, but that was purely coincidental. It does not imply that tariffs “created” a surplus. Nor does it suggest that tariffs might just be able to balance the federal budget. Not a chance!

Here is one of two other sides of the story: the Treasury reported that the budget balance this June improved from a year ago by a total of $89 billion, from a deficit of $72B in June of 2024 to the aforementioned surplus of $27B in June 2025. Outlays were lower by about $38B this June, accounting for almost 43% of the improvement. Receipts were about $59B higher, with tariffs increasing by $20B relative to June 2024. So tariffs contributed just over a third of the boost in receipts. Altogether then, tariffs accounted for 22.5% of the improvement in the June budget balance between 2024 and 2025. That version of the story, as far as it goes, does not support the contention that tariffs “caused” the budget surplus in June, only that tariff revenue was a contributing factor.

Let’s dig a little deeper, however. Were it not for so-called “calendar adjustments” made by the Treasury, it would have reported a deficit of $70B in June. The reason? The first day of June fell on a Sunday this year, so certain payments were shifted to the last prior business day: Friday, May 30. That reduced June outlays substantially. Moreover, an extra business day in June 2025 added revenue. So the surplus in June was, in essence, an artifact of the calendar and had little to do with tariff revenue.

Incidentally, no one should be surprised by the growth of tariff revenue collected in June. When a tax rate more than triples (from a pre-Trump average of about 3% to 10% plus in June — net of tariff exclusions), one should expect revenue from that tax to increase substantially (and it was probably exaggerated by the extra business day).

Oh wait! Did I say tax?

With time, buyers will adjust and scale back their import purchases, reducing the revenue impact of the tariff hikes. However, we still don’t know how high tariffs will go. That means we could see substantially higher tariff revenue, though the demand response and a likely negative impact on incomes will cut into those gains. Either way, the revenue potential of tariffs is limited. Some estimates put the revenue impact of Trump’s tariffs at less than $250B annually. That seems conservative, but it’s significant revenue if it holds up. Still, it won’t come close to balancing a federal budget that’s almost $2 trillion in the hole. It certainly doesn’t justify a headlong dive into protectionism, which amounts to taking a crap on the economic freedom and prosperity of the American public.

DOGE Has Yet To Bite Into Treasury Yields

No sooner had I posted this piece on the bond market’s bemused reaction to DOGE’s cost-cutting potential than Treasury rates began to drop sharply. The 10-year Treasury note fell by about 30 basis points over the course of a week. It’s stabilized and up a little since then, but that drop had little to do with DOGE and everything to do with uncertainty about Trumpian policies and signs of a flagging economy.

Despite those probable causes, the excitement of falling rates prompted the author of this article to dive headlong into fantasy: “Interest Rates Are Falling Thanks to Cuts in Government Spending”. I hope he’s right that real cuts in government spending will be forthcoming, but that’s highly speculative at this point.

In fact, markets are grappling with massive uncertainties at the moment. Under these circumstances, a preference for safety among investors means a flight to low-risk assets like treasuries, forcing their prices up and yields down.

Tariff threats against long-time allies and adversaries alike are a huge source of uncertainty for markets, especially given Trump’s unpredictable thrusts and parries. The burden of U.S. tariffs falls largely on American buyers and tariffs are of limited revenue potential. They have already prompted announcements of retaliation, so the possibility of a trade war is real, which would create a major disruption in economic activity. This portent comes atop growing signs that a slowdown is already underway in the U.S. economy. As Eric Boehm notes, tariffs are all costs and no benefits, and their mere prospect adds significant risk to the economic and political outlook.

Budgetary developments have also been unsettling to markets. Despite promises of reduced federal spending, signs point to even larger deficits. The budget resolution passed by the House of Representatives in late February calls for various spending reductions, but it would extend the Trump tax cuts and increase defense and border control spending. On balance, deficits under the bill would be higher by $4 trillion over 10 years. That is not reassuring, and Trump still wants to eliminate taxes on tips, overtime, and Social Security benefits, which would require separate legislation. State and local tax deductions are also a hot topic. All this obviously undermines the notion that investors should take a rosy view of the outlook for reduced Treasury borrowing under Trump. Of course, higher deficits would be expected to push Treasury rates upward, but the point here is that on balance, DOGE and the Trump Administration have yet to provide a convincing case that rates should decline.

Every week the administration finds a way to demonstrate its lack of seriousness with respect to paying off the public debt. First we had the $5,000 “DOGE dividend” to all Americans. And last week a Strategic Bitcoin Reserve was authorized by Executive Order, to be funded by crypto asset forfeitures and civil penalties. While this type of funding technically qualifies as “budget neutral”, the better alternative would be to put those funds toward paying off debt. In any case, the whole idea makes about as much sense as a Hawk Tuah coin reserve.

The desire for safe assets is perhaps made more urgent by the bellicosity of Trump’s foreign policy initiatives. His multiple mentions of World War III simply can’t go over well with risk-averse investors. Rightly or wrongly, he’s thrown down the gauntlet with both Iran and Hamas, and he’s taken a fairly confrontational line with Greenland, Panama, Canada, Mexico, Venezuela, China, Russia, and especially (and unfairly) Ukraine. Ah, yes, all in the spirit of negotiating deals. We shall see.

As for DOGE, I’m a big fan of its mission to reduce waste and fraud in government, though its reporting of specific accomplishments thus far has been shrouded by inconsistencies and confusion. DOGE claims to have secured $105 billion in savings in the first six weeks of the Trump presidency, but that figure includes asset sales, which can pay down debt but aren’t deficit reduction. It’s also not clear how adverse court orders are reflected in the figure. For that matter, the reported savings are not given with any time dimension. The real savings thus far certainly don’t add up to $105 billion per year. And even at face value, those savings won’t get DOGE to its goal of $2 trillion in deficit reduction by July 2026 without some spectacular wins along the way. Medicaid fraud might be a big one, but that remains to be seen. This report on DEI initiatives by agency also offers some promising targets. (But now, apparently DOGE’s goal has been scaled back to $1 trillion in savings).

And there is one other hurdle: even after DOGE and the Administration identify and impound amounts already authorized, the savings will not be permanent without congressional action on budgetary recissions. That could be tough.

So the bond market is rightly skeptical of whether DOGE and the Administration can achieve major and permanent reductions in federal deficits. The recent drop in rates has much more to do with the economy and an array of uncertainties surrounding the values of risk assets.

Big Spending, Explosive Debt, and the Inflation Tax

The chart above makes a convincing case that we have a spending problem at the federal level. Really, we’ve had a spending problem for a long time. But at least tax revenue today remains reasonably well-aligned with its 50-year historical average as a share of GDP. Not spending. Even larger deficits opened up during the pandemic and they haven’t returned to pre-pandemic levels.

We’ve seen Joe Biden break spending records. His initiatives, often with questionable merit, have included the $1.8 trillion American Rescue Plan and the nearly $0.8 trillion Infrastructure Investment and Jobs Act, along with several other significant spending initiatives such as the Promise to Address Comprehensive Toxics Act and the subsidy-laden CHIPS Act. Meanwhile, emergency spending has become a regular occurrence on Biden’s watch. More recently, he’s made repeated efforts to forgive massive amounts of student loans despite the Supreme Court’s clear ruling that such gifts are unconstitutional.

Indeed, while Biden keeps pretty busy spinning tales of his days driving an 18-wheeler, cannibals devouring his Uncle Bosie Finnegan, his upbringing in black churches, synagogues, or in the Puerto Rican community, he still finds time to dream up ways for the government to spend money it doesn’t have. Or his kindly puppeteers do.

Biden’s New Budget

Eric Boehm expressed wonderment at Biden’s fiscal 2025 budget not long after its release in March. He was also mystified by the gall it took to produce a “fact sheet” in which the White House congratulated itself on fiscal responsibility. That’s how this Administration characterizes deficits projected at $16 trillion over the next ten years. No joke!

Furthermore, the Administration says the record spending will be “paid for”. Well, yes, with tax increases and lots of borrowing! There are a great many fabulist claims made by the White House about the budget. This link from the Office of Management and Budget includes a handy list of propaganda sheets they’ve managed to produce on the virtues of their proposal.

The Congressional Budget Office (CBO) projects ten-year deficits under current law that are $3 trillion higher than Biden’s proposed budget. That’s the basis of the White House’s boast of fiscal restraint. But the difference is basically paid for with a couple of accounting tricks (see below). More charitably, one could say it’s paid for with higher taxes, aided by the assumption of slightly faster economic growth. The latter will be a good trick while undercutting incentives and wages with a big boost to the corporate tax rate.

The revenue projected by the While House from those taxes does not come anywhere close to eliminating the gap shown in the CBO’s chart above. Federal spending under Biden’s budget grows at about 4% annually, just a bit slower than nominal GDP. Thus, the federal share of GDP remains roughly constant and only slightly higher than the CBO’s current projection for 2034. Nevertheless, spending relative to GDP would continue at an historically high rate. Over the next decade, it would average more than 3% higher than its 50-year average. That would be about $1.3 trillion in 2034!

Meanwhile, the ratio of tax revenue to GDP under Biden’s proposal, as they project it, would average slightly higher than its 50-year average, reaching a full percentage point above by 2034 (and higher than the CBO baseline). That’s probably optimistic.

There is little real effort in this budget to reduce federal deficits, with Treasury borrowing rates now near 15-year highs. Interest expense has grown to an alarming share of spending. In fact, it’s expected to exceed spending on defense in 2024! Perhaps not coincidentally, the White House assumes a greater decline in interest rates than CBO over the next 10 years.

Treats or Tricks?

The situation is likely worse than the White House depicts, given that its budget incorporates assumptions that look generous to their claim of fiscal restraint. First, they frontload nondefense discretionary spending, allowing Biden to make extravagant promises for the near-term while pushing off steep declines in budget commitments to the out-years. The sharp reductions in this category of spending pares more than $2 trillion from the 10-year deficit. From the link above:

Biden also proposes to restore the expanded the child tax credit — for one year! How handy from a budget perspective: heroically call for an expanded credit (for a year) while avoiding, for the time being, the addition of a couple of trillion to the 10-year deficit.

Code Red

So where does this end? The ratio of federal debt to GDP will resume its ascent after a slight decline from the pandemic high. Here is the CBO’s projection:

The Biden budget shows a relatively stable debt to GDP ratio through 2034 due to the assumptions of slightly faster GDP growth, lower Treasury borrowing rates, and the aforementioned “fiscal restraint”. But don’t count on it!

The government’s growing dominance over real resources will have negative consequences for growth in the long-term. Purely as a fiscal matter, however, it must be paid for in one of three ways: revenue from explicit taxes, federal borrowing, or an implicit tax on the public more commonly known as the inflation tax. The last two are intimately related.

Bond investors always face at least a small measure of default risk even when lending to the U.S. Treasury. There is almost no chance the government would ever default outright by failing to pay interest or principal when due. However, investors hold an expectation that the value of their bonds will erode in real terms due to inflation. To compensate, they demand an “inflation premium” in the interest rate they earn on Treasury bonds. But an upside surprise to inflation would constitute a “soft default” on the real value of their bonds. This occurred during and after the pandemic, and it was triggered by a burgeoning federal deficit.

Brief Mechanics

John Cochrane has explained the mechanism by which acts of fiscal profligacy can be transmitted to the price of goods. The real value of outstanding federal debt cannot exceed the expected real value of future surpluses (a present value summed across positive and negative surpluses). If expected surpluses are reduced via some emergency or shock such that repayment in real terms is less likely, then the real value of government debt must fall. That means either interest rates or the price level must rise, or some combination of the two.

The Federal Reserve can prevent interest rates from rising (by purchasing bonds and increasing the money supply), but that leaves a higher price level as the only way the real value of debt can come into line. In other words, an unexpected increase in the path of federal deficits would be financed by money printing and an inflation tax. The incidence of this unexpected “implicit” tax falls not only to bondholders, but also on the public at large, who suffer an unexpected decline in the purchasing power of their nominal assets and incomes. This in turn tends to free-up real resources for government absorption.

Government Debt Is Risky

It appears that investors expect the future deficits now projected by the CBO (and the White House) to be paid down someday, to some extent, by future surpluses. That might seem preposterous, but markets apparently aren’t surprised by the projected deficits. After all, fiscal policy decisions can change tremendously over the course of a few years. But it still feels like excessive optimism. Whatever the case, Cochrane cautions that the next fiscal emergency, be it a new pandemic, a war, a recession, or some other crisis, is likely to create another huge expansion in debt and a substantial increase price level. Joe Biden doesn’t seem inclined to put us in a position to deal with that risk very effectively. Unfortunately, it’s not clear that Donald Trump will either. And neither seems inclined to seriously address the insolvencies of Social Security and Medicare. If unaddressed, those mandatory obligations will become real crises over the next decade.

Social Insurance, Trust Fund Runoff, and Federal Debt

The Social Security and Medicare trust funds are starting to shrink, but as they shrink something else expands in tandem, roughly dollar-for-dollar: government debt. There is a widespread misconceptions about these entitlement programs and their trust funds. Many seem to think the trust funds are like “pots of gold” that will allow the government to meet its mandatory obligations to beneficiaries. But, in fact, the government will have to borrow the exact amounts of any “assets” that are “cashed out” of the trust funds, barring other reforms or legislative solutions. So how does that work? And why did I put the words “assets” and “cashed out” in quote marks?

The Trust Funds

First, I should note that there are two Social Security trust funds: one for old age and survivorship income (OASI) and one for disability income (DI). Occasionally, for summary purposes, the accounts for these funds are combined in presentations. There are also two Medicare trust funds: one for hospitalization insurance (HI – Part A) and one for Supplementary Medical Insurance (SMI – Parts B and D). The first three of these trust funds are represented in the chart at the top of this post, which is from the Summary of the 2021 Annual Reports by the Boards of Trustees. It plots a measure of financial adequacy: the ratio of trust fund assets at the start of each year to the annual cost. The funds are all projected to be depleted, HI and OASI much sooner than DI.

Fund Accumulation

The first step in understanding the trust funds requires a clearing up of another misconception: the payroll taxes that workers “contribute” to these systems are not invested specifically for each of those workers. These programs are strictly “pay-as-you-go”, meaning that the payroll taxes (and premiums in the case of Medicare) paid this year by you and/or your employer are generally distributed directly to current beneficiaries.

Back when demographics of the American population were more favorable for these programs, with a larger number of workers relative to retirees, payroll taxes (and premiums) exceeded benefits. The excess was essentially loaned by these programs to the U.S. Treasury to cover other forms of spending. So the trust funds accumulated U.S. Treasury IOUs for many years, and the Treasury pays interest to the trust funds on that debt. On the upside, that meant the Treasury had to borrow less from the public to cover its deficits during those years. So the government spent the excess payroll tax proceeds and wrote IOUs to the trust funds.

Draining the Funds

The demographic profile of the population is no longer favorable to these entitlement programs. The number of retirees has increased so that benefit levels have grown more quickly than program revenue. Benefits now exceed the payroll taxes and premiums collected, so the trust funds must be drawn down. Current estimates are that the Social Security Trust Fund will be depleted in 2034, while the Medicare Trust Fund will last only to 2026. These dates are reflected in the chart above. It is the mechanics of these draw-downs that get to the heart of the first “pot of gold” misconception cited above.

To pay for the excess of benefits over revenue collected, the trust funds must cash-in the IOUs issued to them by the Treasury. And where does the Treasury get the cash? It will almost certainly be borrowed from the public, but the government could hike other forms of taxes or reduce other forms of spending. So, while the earlier accumulation of trust fund assets meant less federal borrowing, the divestment of those assets generally means more federal borrowing and growth in federal debt held by the public.

Given these facts, can you spot the misconception in this quote from Fiscal Tiger? It’s easy to miss:

“In the cases of Social Security, Medicare, and Medicaid, payroll taxes provide some revenue. Social Security also has trust funds that cover some of the program costs. However, when the government is short on funds for these programs after getting the revenue from taxes and trust funds, it must borrow money, which contributes to the deficit.”

This kind of statement is all too common. The fact is the government has to borrow in order to pay off the IOUs as the trust funds are drawn down, roughly dollar-for-dollar.

A second mistake in the quote above is that federal borrowing to pay excess benefits after the trust funds are fully depleted is not really assured. At that time, the Anti-deficiency Act prohibits further payments of benefits in excess of payroll taxes (and premiums), and there is no authority allowing the trust funds to borrow from the general fund of the Treasury. Either benefits must be reduced, payroll taxes increased, premiums hiked (for Medicare), or more radical reforms will be necessary, any of which would require congressional action. In the case of Social Security (combining OASI and DI), the projected growth of “excess benefits” is such that the future, cumulative shortfall represents 25% of projected benefits!

Again, the mandatory entitlement spending programs are technically insolvent. Charles Blahous discusses the implications of closing the funding gap, both in terms of payroll tax increases or benefit cuts, either of which will be extremely unpopular:

“How likely is it that lawmakers would immediately cut benefits by 25% for everyone, rich and poor, retiring next year and beyond? More likely, lawmakers would phase in reforms gradually, necessitating much larger eventual benefit changes for those affected—perhaps 30% or 40%. And if we want to spare lower-income individuals from reductions, they’d need to be still greater for everyone else.”

It should be noted that Medicaid is also a budget drain, though the cost is shared with state governments.

Discretionary vs. Mandatory Budgets

When it comes to federal budget controversies, discretionary budget proposals receive most of the focus. The federal deficit reached unprecedented levels in 2020 and 2021 as pandemic support measures led to huge increases in spending. Even this year (2022), the projected deficit exceeds the 2019 level by over $160 billion. Joe Biden would like to spend much more, of course, though the loss of proceeds from his student loan forgiveness giveaway does not even appear in the Administration’s budget proposal. Biden proposes to pay for the spending with a corporate tax hike and a minimum tax on very high earners, including an unprecedented tax on unrealized capital gains. Those measures would be disappointing in terms of revenue collection, and they are probably worse for the economy and society than bigger deficits. None of that is likely to pass Congress, but we’ll still be running huge deficits indefinitely..

In a further complication, at this point no one really believes that the federal government will ever pay off the mounting public debt. More likely is that the Federal Reserve will make further waves of monetization, buying government bonds in exchange for monetary assets. (Of course, money is also government debt.) The conviction that ever increasing debt levels are permanent is what leads to fiscal inflation, which taxes the public by devaluing the public debt, including (or especially) monetary assets. The insolvency of the trust funds is contributing to this process and its impact is growing..

Again, the budget discussions we typically hear involve discretionary components of the federal budget. Mandatory outlays like Social Security, Medicare, and Medicaid are nearly three times larger. Here is a good primer on the mandatory spending components of the federal budget (which includes interest costs). Blahous notes elsewhere that the funding shortfall in these programs will ultimately dwarf discretionary sources of budgetary imbalance. The deficit will come to be dominated by the borrowing required to fund mandatory programs, along with the burgeoning cost of interest payments on the public debt, which could reach nearly 50% of federal revenues by 2050.

Conclusion

It would be less painful to address these funding shortfalls in mandatory programs immediately than to continue to ignore them. That would enable a more gradual approach to changes in benefits, payroll taxes, and premiums. Politicians would rather not discuss it, however. Any discussion of reforms will be controversial, but it’s only going to get worse over time.

Political incentives being what they are, current workers (future claimants) are likely to bear the brunt of any benefit cuts, rather than retirees already enrolled. Payroll tax hikes are perhaps a harder sell because they are more immediate than trimming benefits for future retirees. Other reforms like self-directed Social Security contributions would create better tradeoffs by allowing investment of contributions at competitive (but more risky) returns. Medicare has premiums as an extra lever, but there are other possible reforms.

Again, the time to act is now, but don’t expect it to happen until the crisis is upon us. By then, our opportunities will have become more hemmed in, and something bad is more likely to be promulgated in the rush to save the day.

Inflation: The Leftist “Tax the Poor” Policy

Recent years have seen explosive growth in federal deficits along with growth rates in the money supply that would have made John Maynard Keynes blush. It’s no coincidence that a new school of thought has developed among certain “monetary economists”. But as someone trained in monetary economics, I wish I could make those quote marks larger. This new school of thought is known as Modern Monetary Theory (MMT), and it asserts that the money spigot is a perfectly legitimate means of financing government spending and, furthermore, that it is not necessarily inflationary. Here is how Scott Sumner and Patrick Horan describe MMT:

“A central idea of MMT is that a government that issues its own fiat currency can pay its bills in that same currency. These governments need not worry about budget deficits when contemplating additional spending. Thus because the US government has a monopoly on money creation, our federal government does not need to raise all its revenue through tax or bond finance. A government with its own currency cannot go bankrupt because it can always issue more currency to cover any budget deficit. … MMT advocates argue that this why the US government can afford expensive programs such as a jobs guarantee and universal healthcare.”

Spend and Print

Joe Biden’s $3.5 trillion “social infrastructure” package would be just a start, but that’s likely to be more like $5.5T once the budget gimmicks are stripped out. We can be somewhat hopeful, because that initiative looks increasingly likely to fail in Congress, at least this time around. But the tax side of that bill was already $2.6T short of the latter spending figure, and the tax provisions keep shrinking. Now, it’s looking more like a shortfall of $3.5T would require financing. Moderate Democrats may not support this crazy bill in the end, but Dems from deep blue states want to reinstate state and local tax deductibility, which would cut the tax component still more. Well who cares? Print the money, say the brave MMT advocates.

Sumner gets to the heart of the problem in this piece. Progressives, with false assurance from MMT, want loose monetary policy to make their expansive programs “affordable”. As he explains, if this happens while the economy is near its production potential, inflation is a sure thing. These lessons were learned long ago, but have been conveniently forgotten by the political class (or they simply prefer to ignore them), instead jumping onto the MMT bandwagon.

Inflation Is Taxation

No conscientious observer of government finance should ever forget that inflation is a form of taxation. Assets whose values are either fixed or subject to some inertia are devalued by inflation in terms of purchasing power, or in real terms, as economists put it. Strictly speaking, this is true when inflation is unexpected… if it is expected, then lenders and borrowers can negotiate terms that will compensate for these changes in real value. But when inflation is unexpected, the losses to lenders are offset by gains to borrowers. Of course the federal government is a gigantic borrower, so inflation can represent a confiscation of wealth from the public.

It’s not small potatoes. Currently, about $22T of U.S. Treasury debt is held by the public, and its average maturity is more than 5 years. If the Federal Reserve engineers an unexpected 1% jump in the rate of inflation, it shaves over $1T off the real value of that debt before it’s repaid, and it reduces the real interest cost of that debt as well. Of course, the holders of that debt will suffer an immediate loss if they are forced to sell prior to maturity for any reason, since new buyers will be demanding higher yields to compensate for higher inflation if it is expected to persist.

The Poor Losers

Inflation causes redistributions to take place, especially when it is unexpected inflation. We’ve already discussed lenders and borrowers, but similar considerations apply to anyone entering into fixed price contracts for goods or labor. Here’s what Claudio Bario of the Bank of International Settlements (BIS) has to say about these shifts:

“Inflation shifts income and wealth away from those who are least aware of it, or least able to protect against it. These segments of the population often coincide with lower-income groups, which explains why inflation has often been portrayed as a most regressive form of tax. The ‘inflation tax’ takes its toll through the erosion of the value of financial assets and contracts fixed in nominal terms.”

Inflation is a regressive tax! In this respect, economist Noah Smith echos Bario in a recent op-ed in which he discusses “money illusion”, or the confusion of real and nominal income:

“Workers … who are slow to perceive the rise in prices they pay for goods like cars and groceries, won’t realize this, and will be happy with their unusually large raises. But companies, whose accountants and managers certainly know the true inflation rate, will also be happy, because they know they’re not actually paying more for labor.

That information asymmetry between workers and employers may be exactly what keeps wages from rising faster than inflation. If workers take a year to realize how much prices have gone up, they may be satisfied with the raises they got during the time of high inflation — even if that inflation ultimately turns out to be transitory. By then, it might be too late to negotiate for a real, inflation-adjusted raise.”

Inflation taxes and redistributions become more acute at higher rates of inflation, but any unexpected escalation in the rate of inflation will take a toll on the poor. Bario elaborates on the mechanisms by which inflation inflicts budgetary pain on the those at the lower end of the socioeconomic spectrum.

“As regards wealth distribution, the financial assets that are most vulnerable to inflation are cash and bank accounts – the typical savings vehicles held by the poorest segments of the population. This is mostly because the poorest have access only to limited investment options to protect their savings. …

… wages and pensions – the main sources of income for a large majority of households and even more so for the poorest half of the population – are typically fixed in nominal terms and hence vulnerable to inflation. Indexation mechanisms, such as those adopted in many [advanced economies] in the 1970s, are no panacea: they may fail to keep pace as inflation accelerates; …”

In addition to the inflationary gains reaped by government, it’s clear that inflation gives rise to redistributions between private parties: generally from those with lower incomes and wealth to their employers, producers, financial institutions, and pension payers (businesses, state and local governments). An exception is some low income debtors might benefit if they owe long term obligations at fixed interest rates, but low income individuals are often constrained from obtaining this form of credit.

Causing, Then Exploiting, Inequality

Another especially galling aspect of the Left’s focus on money finance is how its consequences fly in the face of their concerns about income and wealth inequality. Inflation is typically manifested in rising equity prices: nominal stock values tend to escalate in an inflationary environment, protecting their owners from losses to the real value of their investments. Stocks are generally a good inflation hedge. Yet we know that stocks are disproportionately owned by those in the highest strata of the income and wealth distributions. Later, of course, the Left will seek to level the burgeoning inequality wrought by their own policies by “taxing the rich”! Apparently, for the Left, consistency is never considered a virtue. This is not unlike another trick, which is to blame “greedy corporations” for the inflation wrought by Leftist policies.

It’s a great irony that the Left, which purports to support the poor and working people, would propose a form of government finance that is so regressive in its effects. To be generous, perhaps it’s just another case of “progressives” unknowingly hurting the ones they love. The expansive programs they advocate will confer government benefits to many individuals in higher income brackets, not just the poor, but those government alms will help to compensate for higher inflation. But this too takes advantage of money illusion, because those benefits might well buy progressives the loyalty of beneficiaries unable to recognize the ongoing erosion in their standard of living, and who are unwilling to come to grips with their increasing dependency.

But Tut, Tut, They Say

Advocates of MMT, in combination with expansive government, also have a tendency to deny that inflation has ever been a consequence of such policies. As Sumner points out, they have forgotten historical episodes that run contrary to the theory, and most “popular” advocates of MMT fail to recognize the important role played by limits on the economy’s production potential. When money growth outruns the economy’s ability to produce real goods and services, the prices of goods will rise.
