One Trader Delivers Everything You Wanted To Know About MMT (But Were Afraid To Ask)

"Today’s topic is sure to incite some pretty strong reactions."

If you read only one MacroTourist post all year, this is the one I want you to read. I think it’s that important.

Today’s topic is sure to incite some pretty strong reactions. There will be cries of “no! that’s just wrong!” from the hard-money advocates. The cynics will proclaim “that’s going to end in disaster” and the pessimists will shake their head in disbelief while muttering something about “the follies of the ivory tower academics” as they walk away.

For some of you, the topic of Modern Monetary Theory (MMT) will be old hat. For others, this will be a new term. For those who are not familiar, I suggest you take some time to learn about this new branch of economic thinking as it is coming to a screen near you.

Although I have an opinion about what is best for our economy and society, I am not here to convince you of anything except the fact that MMT is gaining traction, and to remind you that spending time arguing about its relative merits/detriments will not help your trading or investing one iota.

You see, I try to be like that joke; “Dear Optimist and Pessimist, while you were busy debating over whether the glass was half-full or half-empty, I drank it. Signed the Opportunist.”

I know I am nowhere near smart enough to influence policy. So why even try? Nor do I have any desire. So why bother debating it? Yet I love trying to figure out this great big game we call investing. In that vein, putting your head in the sand regarding MMT would definitely be a mistake.

Let me take you through my journey of trying to understand MMT, and along the way, I hope to maybe help a little with your navigating the coming changes in economic thinking.


It was about a year ago when MMT started popping up on my radar. Realizing that all I knew was what the acronym stood for (Modern Monetary Theory), I reached out to Bespoke’s George Pearkes who is a wealth of knowledge when it comes to economic thinking. You see, I am basically a markets guy. George is a markets guy, but there is also a big part of him that is more pure “economist”.

And George was his typical super-nice-guy self. He guided me to some great resources, but ultimately pointed me in the direction of the face of MMT – Professor Stephanie Kelton from Stony Brook University.


Last autumn Professor Kelton gave a speech at Stony Brook University titled “But How Will We Pay for It? If you have an hour to spare, this is probably the best introduction to MMT out there.

[As an aside, George and I recently had a chat about MMT on his podcast BespokeCast. Fast-forward to about half-way to get to the MMT stuff.]

Back to my journey of learning about MMT. Apart from being a professor, Stephanie was also the economic advisor for Bernie Sanders’ campaign.

Given the general more right-leaning bias of people in the finance arena, I can already hear the groans and the clicking to the next article. But wait! Before you go and listen to what Alex Jones is screaming about, remember that your job as an investor is not to forecast what should be but rather focus on what will be.

So let’s get to it. What exactly is MMT?

Modern Monetary Theory is a macroeconomic theory that contends that a country that operates with a sovereign currency has a degree of freedom in their fiscal and monetary policy which means government spending is never revenue constrained, but rather only limited by inflation.


This is my layman’s version after reading and listening to everything I could on the subject, but I think I got the gist of it.

MMT’ers believe that government’s red ink is someone else’s black ink. Sure, the government owes dollars, but they have a monopoly of creating those dollars, and not only that, the creation of more and more dollars is essential to the functioning of the economy.

Here are the policy implications of accepting MMT:

  • governments cannot go bankrupt as long as it doesn’t borrow in another currency
  • it can issue more dollars through a simple keystroke in the ledger (much like the Fed did in the Great Financial Crisis)
  • it can always make all payments
  • the government can always afford to buy anything for sale
  • the government can always afford to get people jobs and pay wages
  • government only faces two different kinds of limitations; political restraint and full employment (which causes inflation)

The government can keep spending until they begin to crowd out the private sector and compete for resources.

And in fact, Stephanie Kelton argues it is immoral to not utilize this power to fix problems in our society. From an interview she gave,

“if you think you can’t repair crumbling infrastructure or feed hungry kids, unless and until you find some money somewhere, it’s actually pretty cruel because you leave people who are struggling in a position where there are still struggling and they are hurting, and they are not properly taken care of…”

I know what you are thinking. Sure sounds like socialism.


But MMT is not socialism. Not by a long shot.

MMT’ers don’t necessarily believe in taxing the wealthy and redistributing it to the poor. Though they do believe the way conventional economics and politicians think about money is wrong.

I know it seems insane to think about the government as not having to worry about deficits and debts. It doesn’t seem to make sense. How can a government just spend money without having to worry about paying it back?

It’s like when Kramer got lost downtown. Remember the terror in his voice when he realized he was at 1st and 1st – where the same street intersects with itself at the nexus of the universe?

But here is another way to think about it. If you have an economy with underused capacity, having the government spend on infrastructure or other societal useful endeavors is actually raising the total GDP of the country.

Yet isn’t that just Keynes theory? Yeah, trying to wrap my head around the difference between Keynes and MMT took me a while, but I think I got it.

Keynesians are still tied to the idea that we are bound by fiscal constraints whereas MMT’ers believe that the only real restraint is inflation.


I heard an economist the other day on Bloomberg say something about the dire state of the global economy because of the stretched balance sheets of the various sovereigns. He said something to the effect of spending will collapse because “who has the capacity for fiscal spending?”

And this is the conventional thinking that prevails almost everywhere.

But MMT’ers would argue that by not spending now, we will be harming our productive capacity in the future. Ultimately it makes no sense to have economic capacity sitting fallow because of a self-imposed worry about paying back a debt that is denominated in an asset that only the government can create.

But, but, but… won’t that create inflation? Yup! Darn right it will, and that’s the point. MMT’ers believe that inflation is the only true constraint a government faces.

As I was learning about MMT it made me wonder if Richard Koo (balance sheet recession fame) was also an MMT’er. After all his belief in the paradox of thrift causing a self-defeating vicious circle seems straight out of MMT’s theories.

So far I have named all these rather left-wing proponents of MMT, but is it truly the domain of the far left? Well, interestingly, former hedge fund manager Warren Mosler has run for office numerous times as a MMT advocate. I dug up this interesting debate between Warren and this Austrian economist.


And while doing my research, I stumbled on this great interview with Professor Steve Keen titled, “Does Modern Monetary Theory make sense?”


I have greatly simplified MMT – no denying that. There were points when I was reading about the relative slope of the IS curve of Keynesians versus MMT’ers and I had a slight moment of panic that I was back in my third-year Economics class after having missed the past two weeks of classes.


How about I try to explain MMT in contrast to the policies of the past decade?

Let’s step back and think about what’s happened in our economy since the Great Financial Crisis and then think about how MMT changes the equation.

There can be no denying that the grand credit super-cycle has seen more and more debt being piled on to an ever growing mound. In 2007 it looked like we had hit the Minsky moment when no more debt could be balanced on the teetering edifice, and when the final piece of the Jenga puzzle was removed, it started to come tumbling down. At this point private credit had entered into a deflationary self-reinforcing credit destruction loop which would have resulted in a cleansing reset of the entire system. Yet this would have been extremely painful and it soon became clear that the government didn’t have the stomach to live through this sort of reset. So they flooded the system with money through quantitative easing – much to the howls of protest from the economic and Wall Street elite who insisted this would cause inflation. But much to almost everyone’s surprise, there was almost no inflation – at least little inflation as we generally think about it. There was plenty of financial asset inflation as all that new money pushed down interest rates and caused asset prices to lift, but the average worker saw little benefit from the Fed’s largesse. You see, even though the Fed was busy buying everything with a CUSIP, the Federal Government was in the midst of one of the biggest cuts in discretionary spending in the history of the United States.

I try to keep my politics to myself, but I can’t hide my feeling that socialism for the rich is not a fair way to run a society. You can’t have a heads-I-win-tails-you-lose situation for banksters and other well-connected parties, but the moment that the economy starts to gain traction, the Fed needs to tamp down on the brakes for fear of inflation.

Regardless of whether you agree with my view or not, it doesn’t matter.

The public has woken up to the fact that supply-side-trickle-down economics is not helping them anywhere near as much as promised.

You might think these sorts of tax-cutting pro-business policies are the best thing for our economy. So be it. Reasonable people can have differing opinions. But the tide is shifting away from this belief, so it really doesn’t matter what you, or I, or even the smartest economist in the world believes.

Society’s mood has changed and Stephanie Kelton’s concepts will continue to gain supporters.

If I had told you four years ago that the following picture wasn’t a photoshop, you would have probably told me I was nuts.


Trump was elected due to a profound disappointment with the status quo. It’s easy to forget but even Obama was elected on a platform of hope and change.

Don’t underestimate how pissed off the average American is (and Canadian, Frenchman, Englishman, etc… for that matter). Monetary stimulus with fiscal austerity doesn’t do anything except make the rich richer.

MMT is novel, ambitious, and a little bit scary. I get it. But let me let you in on a little bit of a secret – young people aren’t afraid of trying something new. They know the system isn’t working and are desperately looking for an alternative. I think they found it in MMT…

Trading Implications

If I am correct, I suspect we will see many Democrat candidates (perhaps all?) adopt MMT as a tenant of their platform. And here is a crazy thought for you – what if Trump beats them to it?

I have long argued that eventually we will hit a period where governments will spend and Central Banks will facilitate their deficits. MMT provides academic justification of where we all know we are headed anyway.

In one of the interviews I watched with Professor Kelton, she said that the idea of deficits being funded with bond issuance is purely a self-imposed limitation. It’s required by law, but in reality, it doesn’t need to be done. The law can be changed. The government could simply spend $100 while only taking in $90 and directly writing cheques against the Federal Reserve to pay for the $10.

Think about how inflationary this will be! But isn’t that the whole goal?

I have always chuckled at the idea that governments were powerless to create inflation. If they want to create inflation – they can. There just needs to be the political will. And it looks like that will has finally arrived.

So what does this mean for your portfolio?

Although I don’t have any concern about the government funding itself, I do have lots of worry that inflation would quickly rise and before too long, the government would be forced to cut back its spending, and that typical of governments, it would prove much more difficult than instituting spending. Therefore I would expect fixed-income to be a terrible investment under MMT. Even if the government pegs rates low, inflation will be the real risk. It would make little sense to sit in an asset that pays fixed.

To me, MMT would scream that the best course would be to buy real productive assets hand over fist.

Ben Hunt had an interesting piece in his excellent blog Epsilon Theory titled, “Modern Monetary Theory or: How I Learned to Stop Worrying and Love the National Debt”. I would argue that he represents conventional Wall Street thinking in terms of his pessimism regarding MMT, but I would like to highlight two terrific points from his writing.

  1. Ben believes MMT will gain traction in the coming years; “Like I said, you may not have heard about MMT yet. But you will. You won’t be able to avoid it. Why? Because MMT is the post hoc justification of both easy fiscal policy and easy monetary policy. As such, it is the new intellectual darling of every political and market Missionary of the Left AND the Right.”
  2. He also contends that MMT will switch QE’s inflation in financial assets to inflation in the real world.


I agree with Ben that MMT will change the type of inflation the economy experiences. I will leave it to much smarter people than I to decide if this is a good or bad thing.

In the meantime, in the coming months, quarters and years, watch for MMT to become a much larger source of change for your portfolio and trading. You might think it’s great and that the financial world could use a change. Or you might think it’s terrible and will be a disaster. Doesn’t matter what you or I think. MMT is coming. Ignoring it would be foolish.

I will leave you with two quotes. One from Ben Hunt and one from Stephanie Kelton. They sum up the battle that will soon envelop the political and financial landscape.

    Thanks for the reference, very interesting.

  2. I like it. Specially the part where citizens are allowed to print their own money to pay their taxes. So there’s never any pain. If the IRS wants a million dollars just print it and send it. What a great scheme.

  3. Actually, this is a good description of Trumponomics — not that Cheetoh could explain it you. Spend money you haven’t raised through taxes to fix longstanding structural problems, and print more $$ to paper over the debts. And if it blows up in your face, fuck it, we’ll all be dead. #MAGA

    • “Apart from being a professor, Stephanie was also the economic advisor for Bernie Sanders’ campaign.”
      Your Trump comment does not square with the source.

  4. In an MMT type system there will always be losers in a globally linked financial system….So read between the lines …you create international turmoil unless you own the one ring that “controls them all “

  5. Why have money as a constraint at all then if debt gets the middle finget? MMT is hipster VR douchebaggery designed not to improve the future, but to scapegoat the past and leave to others permanently the real work needed to get things done.

    Academia needs a hard slap upside the head

  6. Just have the MMT’ers place some dollars in my 401(k) so Donald Trump doesn’t have to ask me on Twitter.

  7. This is very important egg head stuff, definitely worth the effort. To advance the discussion It might be helpful to lay out the theoretical underpinning for MMT to help folks understand the concept at a deeper level (e.g., explain the Faucet and Drain concept of money flowing through the economy and the related formula) – as well as how MMT relates to Debt Monetization, an inflation inducing concept that might come into force if current economic theories prevail, given the level of sovereign debt in the world Understanding these ideas is vital to long range investing strategies.

  8. Harvey Cotton

    MMT is hogwash.

    The far more likely outcome is that that Left, Right, and Center in American politics will come together and agree on a series of entitlement cuts, reduced defense budgets, sensible spending cuts and tax increases that will lead to annual budget surpluses that will used to pay down twenty-one trillion dollars worth of federal debt. The private monies freed up by not buying Treasuries will then be used towards capital expenditures that will boost productivity to the point that the economy will boom despite the reduced government spending, and keep asset, consumer, producer, and wage inflation all in check. The Fed will continue to wind down its holdings of Treasuries and mortgage-backed securities until its balance sheet reaches equilibrium with the amount of currency in circulation and its other liabilities. The excesses built into the system by years of deficit spending and loose monetary policy will wind themselves down gently, with rules-based and orderly restructuring and productivity-boosting bankruptcies that will deflate all asset bubbles with minimal pain. Social cohesion will never be higher.

    Or we implement MMT. One of the two. Who knows?

    • Since the former is delusional the latter is the choice, or this was all satire and there is no choice (see pitchforks below).

  9. Lance Manly

    Seems a majority of the comments don’t notice the people with the pitchforks are coming. The peasants are getting sick of the scraps. Even they can tell Trump screwed them and sent the money to the rich.

    • Bingo!
      Or, as my (seriously-in-student-debt-and-still-worked-my-azz-off-to-live-in-student-housing civil engineer nephew said), “Why should I be so far in debt for 8 coming years, all to be a productive taxpaying member of the US? This country is not a guild!”

      Good question.

  10. Quovadiszero

    After some ponderment; So..if the Confederacy had won the Civil War, the dollar would have become worthless. Iceland had a sovereign currency, right? Does not each financial crisis revolve around inability to refinance/rollover debt?

  11. Um, why’s all that gold in Fort Knox?

  12. The Vietnam War was our first MMT journey. We spent it on that campaign rather than on starving kids. The whole piece here is too low in dimensionality. It is a global economy. And the single currency Eurozone is your laboratory for hypersoverign currency application. MMT induces gaming the induced system. The human element tends to discredit the efficacy of good intentions. And the real problem is that gifted human beings that could act as agents for Pareto optimal human welfare instead would prefer to conclude “it is not my responsibility and I’ll spend $800 on a Superbowl ticket rather than spend time helping my less fortunate neighbor to succeed”. So, as if the government has enough social workers etc. to work with the 40 million heavily disadvantaged humans in the United States alone, we get some pseudointellectual in the SUNY to complain about the billionaires, when the real key is transcendence as an answer to intransigent social reality. Materialist metaphysics is the core foundational problem here. It is so obvious. That is the conceptual underpinning of even trying to model money, when maybe we should prioritize figuring out who we are and better yet, who we can become, not as individuals, but as a whole.

  13. Does mmt lead to stagflation? To Japan-itus?

  14. Another super interesting article – thanks a lot, Mr. Muir!
    Well noted your remarks abt. arguing what should be instead vs. trying to understand what will be – can’t stress that enough.

    However, there are 2 aspects to MMT I am trying to wrap my head around in order to achieve the latter.

    So they flooded the system with money through quantitative easing – much to the howls of protest from the economic and Wall Street elite who insisted this would cause inflation. But much to almost everyone’s surprise, there was almost no inflation – at least little inflation as we generally think about it. There was plenty of financial asset inflation as all that new money pushed down interest rates and caused asset prices to lift, but the average worker saw little benefit from the Fed’s largesse.

    I admit I’m a total rookie when it comes to MMT (currently trying to educate myself using the links provided), but I get the impression the theory does not account for one important factor:
    The tremendous (sorry) deflationary force of
    1) a deluge of cheap labor in China and the rest of East Asia, which is being made accesible to the world via
    2) global trade &
    3) the internet (think Amazon and other online retailers)

    How does monetizing sovereign debt adress this structual issue?

    Also (and this is probably more more within-the-model) I would definitively concur that it makes sense for the government to step in and try to put economic capacity sitting fallow to a better use, but would that not simply constitute Keynesian fiscal stimulus?

    Other than in a liquidity-trap-Situation (here’s Keeeyynes, again :-)) fiscal stimulus is always to be preferred to monetary stimulus.
    One could certainly argue that all efforts of global CBs to re-flate the economy HAD to end in inflation of financial asset prices since the transmission to the real economy is not working as well as expected => governments should have opted for fiscal largesse in fighting the 2008 crisis instead of leaving it to central banks.

    But that is more of a political debate, just as how to put the debt-funded stimulus to the best use (tax cuts for super-rich folks versus investments in infrastructure or social security or preservation of natural or cultural monuments, etc.).

    What I fail to understand is why this constitutes a new MONETARY theory.

    Anybody help?
