The “Magic Formula” Hidden in Yellen’s Big Speech

Janet Yellen’s recent Jackson Hole remarks contain a footnote that’s causing a stir…

In it is a complex mathematical formula that would, for the very first time, put interest rates on “autopilot.”

It looks like this: R(t) = R* + p(t) + 0.5[p(t)-p*]-2.0[U(t)-U*]

Some are calling it a “magic formula” that the Fed may eventually use to dictate every aspect of the economy.

We’re told that by following this sophisticated formula, the Fed will be able to arrive at just the “right” interest rate for whatever economic condition.

Not too hot… not too cold… but just right… like Goldilocks’ porridge in the famous fairy tale.

Comparison to a fairy tale is apt because the idea that a centrally derived “magic formula” can arrive at a “proper” interest rate is pure fantasy.

It is magical thinking to imagine we have supernatural beings in our central banks with the ability to cast a spell on mind-bogglingly complex global economies and markets to achieve a beneficial result for all.

What’s worse, as Ben Hunt, Chief Risk Officer of Salient Partners, describes below, we’ve now arrived at a time in our history where we can no longer imagine solutions to any of our economic and political problems that don’t involve increasing reliance on these supposed benevolent kings and queens.

It’s this type of dangerous thinking that has furthered the worst impulses of humanity throughout history. And Ben believes that if we don’t change course quickly, it’s going to cause a real nightmare for everyone.

Magical Thinking

By W. Ben Hunt, Ph.D.

Magical thinking is a term of art in both clinical psychology and cultural anthropology, and it refers to the common belief among both children and “primitive” societies (yes, intentional quotation marks there to show my arched eyebrow at the word) that thinking the right thoughts or saying the right words can control the invisible forces that shape our world.

For example, as Jean Piaget (the father of developmental psychology) noted, children from the ages of 2 to 7 tend to have very little conception of real-world causality.

Tell your four-year-old son that the family dog has died, and he is likely to a) blame himself for something he did or didn’t do for “causing” the death, and b) believe that there is some combination of proper words and proper thoughts and proper actions that can make the dog come back to life. That’s magical thinking.

It’s a profoundly egocentric conception of the world, and if you’re a parent you know exactly what Piaget is talking about. Every four-year-old child is an egomaniac, in the clinical, non-judgmental sense of the word.

It’s the same thing with what cultural anthropologist Claude Levi-Strauss called “The Savage Mind” in his groundbreaking 1962 book. Societies without a causal explanation for, say, the weather will always construct some sort of combination of words and thoughts and actions to be performed by privileged caste members like priests or kings, through which the entire society convinces itself that humans exercise some sort of control over these incredibly powerful real-world forces and that they aren’t just buffeted this way and that by the inexorable might of a big bad world that really couldn’t care less about them.

In early days of any human society, this sort of magic usually emphasizes some form of sympathetic or like-for-like object.  For example, you might rub a banana-shaped crocodile tooth against a banana plant to make it bear fruit (I’m not making this up).

Over time, however, the spell-casting caste and society at large convince themselves that you don’t really need actual crocodile teeth, but you can instead invoke the power of a crocodile tooth by calling it by its secret name.

Maybe you need to write down that secret name using the secret language of the priests in order to make the spell work, but you definitely don’t need to go out and hunt down a real-world crocodile.

It’s at this point that hunter/soldier-kings are replaced by academic/priest-kings… the pen is truly mightier than the sword, or at least writing “crocodile” carries a longer life expectancy than hunting crocodiles.

Over still more time, the secret names and the secret language of the priest-kings become a vast edifice of magical thinking, an edifice that provides great comfort and stability to the entire society. Because there is nothing more important to societal stability than the belief that nature is under control. That the invisible forces of nature can, in fact, be prayed away.

Until they can’t. Until all the banana plants die because of some rare nematode infestation in the roots, and all the secret words and secret languages and even the “old magic” of the actual crocodile teeth are useless.

They were useless all along, of course, as the banana plants would have borne fruit for the past 50 years with or without the spells, but hey… until this year there was a 98% correlation between the spells and a healthy banana crop! And my VAR was really quite negligible!

Okay, Ben, we see what you’ve done here. Yes, yes… quite droll, really … you’ve found a clever metaphor for railing against our central banker ruling class. Again. Thanks for the diversion, but now we need to get back to planet Earth. Important work to be done, and all that. Love your quotes, by the way.

Wait! This is not a metaphor. This is not an anthropological parable for our times. This IS our times. Want to see what a magic spell looks like? Here you go:


This is the Gaussian Copula spell. It’s what you write down to make sure that your AAA-rated slice of a massive bunch of mortgages pays you 6% a year with only an infinitesimal risk of default.

It’s not a metaphor for a spell. It is an actual magic spell, exactly the same in form and function as the talismanic scripts written on, say, Egyptian funerary urns in 1000 BC to make sure that your body and soul get to the afterlife with only an infinitesimal risk of default.

Secret language no one can read or understand? Check. Not really comprehensible even by most magicians? Check. Administered by a privileged caste with appropriate pomp and ceremony? Check. Reflective of an innate human desire to control invisible forces that are, in fact, uncontrollable and inexorable, like death and business cycles? Check. Highly effective in motivating human behavior and supporting status quo political institutions? Check. And mate.

The Gaussian Copula spell wishes away the possibility of a nationwide decline in U.S. home prices (if you haven’t already, please read Felix Salmon’s 2009 Wired magazine article on the Gaussian Copula — “The Formula That Broke Wall Street” — my all-time favorite piece of financial market journalism).

The magical thinking embedded in this spell is that a nationwide decline in U.S. home prices is not just unlikely, it is — literally — unthinkable.

It is an incantation that generated enormous societal stability and wealth, creating out of whole cloth a belief that a $10 trillion (yes, that’s trillion with a T) asset class in residential mortgage-backed securities (RMBS) was a solid thing, a triumph of Science (why, just look at all those Greek letters and the mathematical stuff!), an example of man’s mastery over the invisible vagaries of nature.

And then we had a nationwide decline in U.S. home prices. Which broke our world.

Here’s another spell:


This is the Taylor Rule spell. It’s what you write down to make sure that the inflation rate in your economy goes up or down the way you want it to go up or down. There are lots of other spells that go along with the Taylor Rule spell for “controlling” inflation, but it’s the main one, I’d say.

This is the spell that has created a $12 trillion asset class in negative-yielding sovereign debt. Because, you know, the lower interest rates go, the more you’re going to borrow and spend, and the higher inflation goes. Right? Right?

If the Gaussian Copula is like a funerary spell, trying to assure investors that they will get to investor heaven like dead Egyptian Pharaohs were assured of getting to dead Egyptian Pharaoh heaven, the Taylor Rule is like a weather spell. When I read this from James Frazer’s “The Golden Bough”:

So in Scotland witches used to raise the wind by dipping a rag in water and beating it thrice on a stone, saying:

I knok this rag upone this stane
To raise the wind in the divellis name,
It sall not lye till I please againe.

I can’t help but think of Stanley Fischer, vice-warlock of the Fed coven, saying in Jackson Hole that we need thrice interest rate raises (one last December, two more this year) to quell the inflationary winds. Or raise them. Or whatever sort of weather that Fischer is trying to manufacture. It’s really hard to tell.

But here’s the kicker. When a spell doesn’t work, no one in the magically thinking society believes it’s because spell casting itself doesn’t work. It means that the spell wasn’t performed properly.

Either the priest-kings said the words wrong or they didn’t think the right thoughts or there’s some other invisible force that we need to propitiate first. So what always happens, and I mean “always” in the sense of This. Is. Human. Nature. And has been happening in a rhyming sense for tens of thousands of years across every human society that ever lived, is this:

In phase 1, the priest-kings try harder. They seek out purer ingredients for their spells. They speak more loudly, more convincingly, more stridently. If two crocodile teeth were used in the past, now they use four. Or eight. It’s not just “more”, it’s “MOAR!.” Often there’s an internal purge near the end of phase 1.

In phase 2, the priest-kings regroup and tweak the spell. Maybe instead of “targeting” (another word for “praying for”) a 2% inflation rate, we need to “target” a 4% inflation rate.

Maybe we should change the magic word “inflation” to “nominal GDP growth” and see if that works any better. Sure, why not? This tweaking process has happened, it is happening now, and it will happen all the way to the bitter end.

What will never happen is that the priest-kings quit. There’s always another tweak, always another word choice, always another order in which the words can be said.

In phase 3 — and this is where we are now in the historical process, somewhere near the end of phase 2 and the beginning of phase 3 — the priest-kings are challenged by a rogue priest in their midst (rare) or an alt-priest coming out of nowhere (common).

By “nowhere” I mean that the alt-priest is an Other, whether that’s a foreign religion or a foreign geography or a foreign (i.e., non-priestly) caste.

The alt-priest isn’t about tweaking the spell or casting it louder. He’s about doing an entirely different spell, and he’s about accusing the incumbent priests of incompetence or worse. The alt-priest is always a populist, and populism comes easy when the incumbent spells have been failing… and failing… and failing.

So what happens? It depends on reality. It depends on whether the banana plants get better on their own… or if they die.

If they get better on their own (and this happens more often than you might think), then the incumbent priest-kings remain. If the banana plants give up the ghost, then the incumbents are swept away.

Interestingly — and this was Frazer’s big point in “The Golden Bough” — even if the incumbent mode of magical thinking survives, it’s necessary for societal stability to perform a public human sacrifice of the primary incumbent priest-king. The king is dead. Long live the king.

Fortunately for all involved, human sacrifice today is a lot less literal than it was during, I dunno, the heyday of the Etruscans. A little public shaming, a tearful interview with Anderson Cooper, a quiet hermitage in the form of a deanship at a small New England college … yeah, that should do the trick.

The way this all plays out also depends on how deeply the incumbent priest-kings retreat into their fantasy world of tweaking spells and magical thinking, and that’s where I’m most concerned.

The fact is that the global economy — particularly the U.S. economy and the Chinese economy — is more robust than the alt-priests tend to let on. Amazingly enough, the U.S. can still grow its way out of the massive debt we’ve taken on. I know… hard to believe. But it’s true.

The power of compounding is truly inexorable, and it’s amazing what a steady 3.5% growth rate on a huge economic base can do to make manageable even trillions of dollars in debt.

The rest of the developed world? Impossible to grow their way out of debt. They’re finished. Or rather, to use the lingo of my distressed debt friends, Japan and Europe ex-Germany are now “work-out situations.”

But if the U.S. could just get out of its own way… if we could stop arguing about who gets to use what bathroom and start arguing about how to increase productivity (i.e., how to make technology a tool for humans doing more stuff rather than a replacement for humans doing stuff at all)… then we could actually come out of this okay.

I know, I know… I’m a dreamer. And for all the political fragmentation and polarization reasons that I write about ad nauseam, the politics of identity are unlikely to be replaced by the politics of growth anytime soon. Not in the West, anyway. But that’s why I want to pull my hair out when I watch the Jackson Hole theatre. Guys, you’re not helping!

I was dumbfounded by the stultifying, excruciating more-of-the-sameness that came out of Jackson Hole. Oh my God, are we really saying that the entire FOMC decision-making process comes down to whether there’s a good jobs report on Friday? Why don’t we just inspect the entrails of a goat?

Are we really still arguing about one-raise-or-two when LIBOR is now pushing 90 basis points? Was there any mention — any mention at all — of LIBOR during the entire Jackson Hole meeting?

Do these people, and it’s not just the central bankers themselves but all the courtiers — the journalists, the academics, the hangers-on — do they even recognize that a world exists outside of their imaginations and theories? Answer: NO.

Yep, at first I was disappointed in them. But on reflection, I became more and more disappointed in us.

See, the problem isn’t with the Fed. They’re going to do what solipsistic, magical thinking priest-kings have done for ten thousand years… more of THAT. More solipsism. More magical thinking. More four-year-old egomaniacal determination that their spell-casting efforts are the ONLY thing that stand between us and utter ruin.

No, the bigger problem is with us. The bigger problem is that we cannot imagine a solution for our current economic and political problems that does not rely on greater and greater state-directed spell casting.

Monetary policy spells not working? Well, golly, I guess our ONLY alternative is to try some fiscal policy spells. Really? That’s the best we can come up with? I understand that this is what the courtiers are going to say. But I expect more from the rest of us. I expect more from myself.

Look, I get it. To riff on Woody Allen’s famous joke, we need the eggs. We need a stock market that goes up, not down. We need financial asset price inflation.

We need the eggs so badly that we’re willing to support the magical thinking crew and smile at their courtiers even though we think they’re totally out of touch with reality. We’ve become so used to getting our eggs delivered on time and without fail that our first, second, and third responses are to ask for more magical thinking from the incumbent priest-kings, not less.

This is a dangerous, myopic game. Because we will get what we ask for. We will get more magical thinking. Only it won’t come just from the status quo magicians. It will also come from the alt-priests, some of whom will represent the absolute worst impulses of humanity.

There are really bad ideas lurking on the wings today — there always are — but these really bad ideas about how human society should be organized always resurface and grow more powerful at times like this. Because it’s the old magic, an old magic that the human animal is hard-wired to respond to.

Maybe we’ll get lucky. Maybe the banana plants of global growth will turn green again, and we can have a grand celebration of the particular variant of the policy spell that was coincidentally cast at the same time. That could happen.

As Otto von Bismarck, the Iron Chancellor of 19th century Europe supposedly said, “There is a special providence for children, fools, and the United States of America.” Any portfolio manager with long enough tenure knows what it’s like to be bailed out by the market, and it’s a beautiful thing. Now we just need that to happen on a much larger scale.

But we should do better than just trust to luck. I’m not saying that we have to deny our human nature and stop believing in the act of spell-casting itself. I’m not (that) delusional.

What I’m saying is that the more we embrace and encourage state-directed magical thinking, whether it’s of the monetary or fiscal policy sort, what we are actually doing is opening the city gates to the old evil magic and the alt-priests of fascism and totalitarianism.

We don’t need the eggs that badly. What I’m saying is that we need to think less about Scottish witchcraft, a la Macbeth and James Frazer and Stanley Fischer, and more about the Scottish Enlightenment, a la David Hume and Adam Smith and Alexander Hamilton.

What I’m saying is that we need to focus on empiricism and on what works in the real world, not theory and what “works” as an equation.

What I’m saying is that usually the better course of state-directed action is to do less, not more, and the better course of individually directed action is to do more, not less.

What I’m saying is that the old good magic of “small-l” liberalism and technological innovation in the service of man rather than the replacement of man is pretty darn powerful itself, and the stories still inspire. Let’s embrace and encourage THAT as we make our way through what is still a largely inexorable world.

It matters whether or not we call things by their proper names, because the words and the spells motivate human behavior like nothing else.

It matters whether or not we sleepwalk our way through our own fin de siècle, because the really bad people and the really bad ideas that periodically wreck our world can’t be wished away.

It matters whether or not we become courtiers ourselves, because the courtiers always fall the farthest. The problem with magical thinking run amok and its perpetuation of a fantasy world is that sooner or later the dream of the delusional king becomes a real world nightmare for real world people. It’s time to wake up.
