How the economic machine works, in 30 minutes.
The economy works like a simple machine.
But many people don’t understand it
— or they don’t agree on how it works
— and this has led to a lot of needless economic suffering.
I feel a deep sense of responsibility
to share my simple but practical economic template.
Though it’s unconventional,
it has helped me to anticipate and sidestep the global financial crisis,
and has worked well for me for over 30 years.
Though the economy might seem complex, it works in a simple, mechanical way.
It’s made up of a few simple parts and a lot of simple transactions
that are repeated over and over again a zillion times.
These transactions are above all else driven by human nature,
and they create 3 main forces that drive the economy.
Number 1: Productivity growth
Number 2: The Short term debt cycle
and Number 3: The Long term debt cycle
We’ll look at these three forces and how laying them on top of each other
creates a good template for tracking economic movements
and figuring out what’s happening now.
Let’s start with the simplest part of the economy:
An economy is simply the sum of the transactions that make it up
and a transaction is a very simple thing.
You make transactions all the time.
Every time you buy something you create a transaction.
Each transaction consists of a buyer
exchanging money or credit
with a seller for goods, services or financial assets.
Credit spends just like money,
so adding together the money spent and the amount of credit spent,
you can know the total spending.
The total amount of spending drives the economy.
If you divide the amount spent
by the quantity sold,
you get the price.
And that’s it. That’s a transaction.
It is the building block of the economic machine.
All cycles and all forces in an economy are driven by transactions.
So, if we can understand transactions,
we can understand the whole economy.
A market consists of all the buyers
and all the sellers
making transactions for the same thing.
For example, there is a wheat market,
a car market,
a stock market
and markets for millions of things.
An economy consists of all of the transactions
in all of its markets.
If you add up the total spending
and the total quantity sold
in all of the markets,
you have everything you need to know
to understand the economy.
It’s just that simple.
People, businesses, banks and governments
all engage in transactions the way I just described:
exchanging money and credit for goods, services and financial assets.
The biggest buyer and seller is the government,
which consists of two important parts:
a Central Government that collects taxes and spends money…
…and a Central Bank,
which is different from other buyers and sellers because it
controls the amount of money and credit in the economy.
It does this by influencing interest rates
and printing new money.
For these reasons, as we’ll see,
the Central Bank is an important player in the flow
I want you to pay attention to credit.
Credit is the most important part of the economy,
and probably the least understood.
It is the most important part because it is the biggest
and most volatile part.
Just like buyers and sellers go to the market to make transactions,
so do lenders and borrowers.
Lenders usually want to make their money into more money
and borrowers usually want to buy something they can’t afford,
like a house or car
or they want to invest in something like starting a business.
Credit can help both lenders
and borrowers get what they want.
Borrowers promise to repay the amount they borrow,
called the principal,
plus an additional amount, called interest.
When interest rates are high,
there is less borrowing because it’s expensive.
When interest rates are low,
borrowing increases because it’s cheaper.
When borrowers promise to repay
and lenders believe them,
credit is created.
Any two people can agree to create credit out of thin air!
That seems simple enough but credit is tricky
because it has different names.
As soon as credit is created,
it immediately turns into debt.
Debt is both an asset to the lender,
and a liability to the borrower.
In the future,
when the borrower repays the loan, plus interest,
the asset and liability disappear
and the transaction is settled.
So, why is credit so important?
Because when a borrower receives credit,
he is able to increase his spending.
And remember, spending drives the economy.
This is because one person’s spending
is another person’s income.
Think about it, every dollar you spend, someone else earns.
and every dollar you earn, someone else has spent.
So when you spend more, someone else earns more.
When someone’s income rises
it makes lenders more willing to lend him money
because now he’s more worthy of credit.
A creditworthy borrower has two things:
the ability to repay and collateral.
Having a lot of income in relation to his debt gives him the ability to repay.
In the event that he can’t repay, he has valuable assets to use as collateral that can be sold.
This makes lenders feel comfortable lending him money.
So increased income allows increased borrowing
which allows increased spending.
And since one person’s spending is another person’s income,
this leads to more increased borrowing and so on.
This self-reinforcing pattern leads to economic growth
and is why we have Cycles.
In a transaction, you have to give something in order to get something
and how much you get depends on how much you produce
over time we learned
and that accumulated knowledge raises are living standards
we call this productivity growth
those who were invented and hard-working raise
their productivity and their living standards faster
than those who are complacent and lazy,
but that isn’t necessarily true over the short run.
Productivity matters most in the long run, but credit matters most in the short run.
This is because productivity growth doesn’t fluctuate much,
so it’s not a big driver of economic swings.
Debt is — because it allows us to consume more than we produce when we acquire it
and it forces us to consume less than we produce when we pay it back.
Debt swings occur in two big cycles.
One takes about 5 to 8 years and the other takes about 75 to 100 years.
While most people feel the swings, they typically don’t see them as cycles
because they see them too up close — day by day, week by week.
In this chapter we are going to step back and look at these three big forces
and how they interact to make up our experiences.
As mentioned, swings around the line are not due to how much innovation or hard work there is,
they’re primarily due to how much credit there is.
Let’s for a second imagine an economy without credit.
In this economy, the only way I can increase my spending
is to increase my income,
which requires me to be more productive and do more work.
Increased productivity is the only way for growth.
Since my spending is another person’s income,
the economy grows every time I or anyone else is more productive.
If we follow the transactions and play this out,
we see a progression like the productivity growth line.
But because we borrow, we have cycles.
This isn’t due to any laws or regulation,
it’s due to human nature and the way that credit works.
Think of borrowing as simply a way of pulling spending forward.
In order to buy something you can’t afford, you need to spend more than you make.
To do this, you essentially need to borrow from your future self.
In doing so you create a time in the future
that you need to spend less than you make in order to pay it back.
It very quickly resembles a cycle.
Basically, anytime you borrow you create a cycle.?
This is as true for an individual as it is for the economy.
This is why understanding credit is so important
because it sets into motion
a mechanical, predictable series of events that will happen in the future.
This makes credit different from money.
Money is what you settle transactions with.
When you buy a beer from a bartender with cash,
the transaction is settled immediately.
But when you buy a beer with credit,
it’s like starting a bar tab.
You’re saying you promise to pay in the future.
Together you and the bartender create an asset and a liability.
You just created credit. Out of thin air.
It’s not until you pay the bar tab later
that the asset and liability disappear,
the debt goes away
and the transaction is settled.
The reality is that most of what people call money is actually credit.
The total amount of credit in the United States is about $50 trillion
and the total amount of money is only about $3 trillion.
Remember, in an economy without credit:
the only way to increase your spending is to produce more.
But in an economy with credit,
you can also increase your spending by borrowing.
As a result, an economy with credit has more spending
and allows incomes to rise faster than productivity over the short run,
but not over the long run.
Now, don’t get me wrong,
credit isn’t necessarily something bad that just causes cycles.
It’s bad when it finances over-consumption that can’t be paid back.
However, it’s good when it efficiently allocates resources
and produces income so you can pay back the debt.
For example, if you borrow money to buy a big TV,
it doesn’t generate income for you to pay back the debt.
But, if you borrow money to buy a tractor —
and that tractor let’s you harvest more crops and earn more money
— then, you can pay back your debt
and improve your living standards.
In an economy with credit,
we can follow the transactions
and see how credit creates growth.
Let me give you an example:
Suppose you earn $100,000 a year and have no debt.
You are creditworthy enough to borrow $10,000 dollars
– say on a credit card
– so you can spend $110,000 dollars
even though you only earn $100,000 dollars.
Since your spending is another person’s income,
someone is earning $110,000 dollars.
The person earning $110,000 dollars
with no debt can borrow $11,000 dollars,
so he can spend $121,000 dollars
even though he has only earned $110,000 dollars.
His spending is another person’s income
and by following the transactions
we can begin to see how this process
works in a self-reinforcing pattern.
But remember, borrowing creates cycles
and if the cycle goes up, it eventually needs to come down.
This leads us into the Short Term Debt Cycle.
As economic activity increases, we see an expansion
– the first phase of the short term debt cycle.
Spending continues to increase and prices start to rise.
This happens because the increase in spending is fueled by credit
– which can be created instantly out of thin air.
When the amount of spending and incomes grow faster than the production of goods:
When prices rise, we call this inflation.
The Central Bank doesn’t want too much inflation
because it causes problems.
Seeing prices rise, it raises interest rates.
With higher interest rates, fewer people can afford to borrow money.
And the cost of existing debts rises.
Think about this as the monthly payments on your credit card going up.
Because people borrow less and have higher debt repayments,
they have less money leftover to spend, so spending slows
…and since one person’s spending is another person’s income,
incomes drop…and so on and so forth.
When people spend less, prices go down.
We call this deflation.
Economic activity decreases and we have a recession.
If the recession becomes too severe
and inflation is no longer a problem,
the central bank will lower interest rates to cause everything to pick up again.
With low interest rates,
debt repayments are reduced
and borrowing and spending pick up
and we see another expansion.
As you can see, the economy works like a machine.
In the short term debt cycle, spending is constrained only by the willingness of
lenders and borrowers to provide and receive credit.
When credit is easily available, there’s an economic expansion.
When credit isn’t easily available, there’s a recession.
And note that this cycle is controlled primarily by the central bank.
The short term debt cycle typically lasts 5 – 8 years
and happens over and over again for decades.
But notice that the bottom and
top of each cycle finish
with more growth than the previous cycle and with more debt.
Because people push it
— they have an inclination to borrow and spend more instead of paying back debt.
It’s human nature.
Because of this,
over long periods of time,
debts rise faster than incomes
creating the Long Term Debt Cycle.
Despite people becoming more indebted,
lenders even more freely extend credit.
Because everybody thinks things are going great!
People are just focusing on what’s been happening lately.
And what has been happening lately?
Incomes have been rising!
Asset values are going up!
The stock market roars!
It’s a boom!
It pays to buy goods, services, and financial assets
with borrowed money!
When people do a lot of that, we call it a bubble.
So even though debts have been growing,
incomes have been growing nearly as fast to offset them.
Let’s call the ratio of debt-to-income the debt burden.
So long as incomes continue to rise,
the debt burden stays manageable.
At the same time asset values soar.
People borrow huge amounts of money
to buy assets as investments
causing their prices to rise even higher.
People feel wealthy.
So even with the accumulation of lots of debt,
rising incomes and asset values help borrowers remain creditworthy for a long time.
But this obviously can not continue forever.
And it doesn’t.
Over decades, debt burdens slowly increase creating larger and larger debt repayments.
At some point, debt repayments start growing faster than incomes
forcing people to cut back on their spending.
And since one person’s spending is another person’s income,
incomes begin to go down…
…which makes people less creditworthy causing borrowing to go down.
Debt repayments continue to rise
which makes spending drop even further…
…and the cycle reverses itself.
This is the long term debt peak.
Debt burdens have simply become too big.
For the United States, Europe and much of the rest of the world this
happened in 2008.
It happened for the same reason it happened in Japan in 1989
and in the United States back in 1929.
Now the economy begins Deleveraging.
In a deleveraging; people cut spending,
incomes fall, credit disappears,
assets prices drop, banks get squeezed,
the stock market crashes, social tensions rise
and the whole thing starts to feed on itself the other way.
As incomes fall and debt repayments rise,
borrowers get squeezed. No longer creditworthy,
credit dries up and borrowers can no longer borrow enough money to make their
Scrambling to fill this hole, borrowers are forced to sell assets.
The rush to sell assets floods the market
This is when the stock market collapses,
the real estate market tanks and banks get into trouble.
As asset prices drop, the value of the collateral borrowers can put up drops.
This makes borrowers even less creditworthy.
People feel poor.
Credit rapidly disappears. Less spending ›
less income ›
less wealth ›
less credit ›
less borrowing and so on.
It’s a vicious cycle.
This appears similar to a recession but the difference here
is that interest rates can’t be lowered to save the day.
In a recession, lowering interest rates works to stimulate the borrowing.
However, in a deleveraging, lowering interest rates doesn’t work because
interest rates are already
low and soon hit 0% – so the stimulation ends.
Interest rates in the United States hit 0% during the deleveraging of
and again in 2008.
The difference between a recession
and a deleveraging is that in a deleveraging borrowers’ debt burdens have
simply gotten too big
and can’t be relieved by lowering interest rates.
Lenders realize that debts have become too large to ever be fully paid back.
Borrowers have lost their ability to repay and their collateral has lost value.
They feel crippled by the debt – they don’t even want more!
Lenders stop lending. Borrowers stop borrowing.
Think of the economy as being not-creditworthy,
just like an individual.
So what do you do about a deleveraging?
The problem is debt burdens are too high and they must come down.
There are four ways this can happen.
1. people, businesses, and governments cut their spending.
2. debts are reduced through defaults and restructurings.
3. wealth is redistributed from the ‘haves’ to the ‘have nots’.
and finally, 4. the central bank prints new money.
These 4 ways have happened in every deleveraging in modern history.
Usually, spending is cut first.
As we just saw, people, businesses, banks and even governments tighten their belts and
cut their spending so that they can pay down their debt.
This is often referred to as austerity.
When borrowers stop taking on new debts,
and start paying down old debts, you might expect the debt burden to decrease.
But the opposite happens! Because spending is cut
– and one man’s spending is another man’s income – it causes
incomes to fall. They fall faster than debts are repaid
and the debt burden actually gets worse. As we’ve seen,
this cut in spending is deflationary and painful.
Businesses are forced to cut costs…
which means less jobs and higher unemployment.
This leads to the next step: debts must be reduced!
Many borrowers find themselves unable to repay their loans
— and a borrower’s debts are a lender’s assets.
When borrowers don’t repay the bank, people get nervous that the bank won’t
be able to repay them
so they rush to withdraw their money from the bank. Banks get squeezed and
businesses and banks default on their debts. This severe
economic contraction is a depression.
A big part of a depression is people discovering much of what they thought
was their wealth isn’t really there.
Let’s go back to the bar.
When you bought a beer and put it on a bar tab,
you promised to repay the bartender. Your promise became an asset of the bartender.
But if you break your promise – if you don’t pay him back and essentially default
on your bar tab –
then the ‘asset’ he has isn’t really worth anything.
It has basically disappeared.
Many lenders don’t want their assets to disappear and agree to debt
Debt restructuring means lenders get paid back
less or get paid back over a longer time frame
or at a lower interest rate that was first agreed. Somehow
a contract is broken in a way that reduces debt. Lenders would rather have a
little of something than all of nothing.
Even though debt disappears, debt restructuring causes
income and asset values to disappear faster,
so the debt burden continues to gets worse.
Like cutting spending, debt reduction
is also painful and deflationary.
All of this impacts the central government because lower incomes and less employment
means the government collects fewer taxes.
At the same time it needs to increase its spending because unemployment has risen.
Many of the unemployed have inadequate savings
and need financial support from the government.
Additionally, governments create stimulus plans
and increase their spending to make up for the decrease in the economy.
Governments’ budget deficits explode in a
deleveraging because they spend more than they earn in taxes.
This is what is happening when you hear about the budget deficit on the news.
To fund their deficits, governments need to either raise taxes
or borrow money. But with incomes falling and so many unemployed,
who is the money going to come from? The rich.
Since governments need more money and since wealth is heavily concentrated in
the hands of a small percentage of the people,
governments naturally raise taxes on the wealthy
which facilitates a redistribution of wealth in the economy –
from the ‘haves’ to the ‘have nots’. The ‘have-nots,’ who are suffering, begin to
resent the wealthy ‘haves.’
The wealthy ‘haves,’ being squeezed by the weak economy, falling asset prices,
higher taxes, begin to resent the ‘have nots.’
If the depression continues social disorder can break out.
Not only do tensions rise within countries,
they can rise between countries – especially debtor and creditor countries.
This situation can lead to political change
that can sometimes be extreme.
In the 1930s, this led to Hitler coming to power,
war in Europe, and depression in the United States. Pressure to do something
to end the depression increases.
Remember, most of what people thought was money was actually credit.
So, when credit disappears, people don’t have enough money.
People are desperate for money and you remember who can print money?
The Central Bank can.
Having already lowered its interest rates to nearly 0
– it’s forced to print money. Unlike cutting spending,
debt reduction, and wealth redistribution,
printing money is inflationary and stimulative. Inevitably, the central bank
prints new money
— out of thin air — and uses it to buy financial assets
and government bonds. It happened in the United States during the Great Depression
and again in 2008, when the United States’ central bank —
the Federal Reserve — printed over two trillion dollars.
Other central banks around the world that could, printed a lot of money, too.
By buying financial assets with this money,
it helps drive up asset prices which makes people more creditworthy.
However, this only helps those who own financial assets.
You see, the central bank can print money but it can only buy financial assets.
The Central Government, on the other hand,
can buy goods and services and put money in the hands of the people
but it can’t print money. So, in order to stimulate the economy, the two
By buying government bonds, the Central Bank essentially lends money to the
allowing it to run a deficit and increase spending
on goods and services through its stimulus programs
and unemployment benefits. This increases people’s income
as well as the government’s debt. However,
it will lower the economy’s total debt burden.
This is a very risky time. Policy makers need to balance the four ways that debt
burdens come down.
The deflationary ways need to balance with the inflationary ways in
order to maintain stability.
If balanced correctly, there can be a
You see, a deleveraging can be ugly or it can be beautiful.
How can a deleveraging be beautiful?
Even though a deleveraging is a difficult situation,
handling a difficult situation in the best possible way is beautiful.
A lot more beautiful than the debt-fueled, unbalanced excesses of the
leveraging phase. In a beautiful deleveraging,
debts decline relative to income, real economic growth is positive,
and inflation isn’t a problem. It is achieved by having the right balance.
The right balance requires a certain mix
of cutting spending, reducing debt, transferring wealth
and printing money so that economic and social stability can be maintained.
People ask if printing money will raise inflation.
It won’t if it offsets falling credit. Remember, spending is what matters.
A dollar of spending paid for with money has the same effect on price as a dollar
of spending paid for with credit.
By printing money, the Central Bank can make up for the disappearance of credit
with an increase in the amount of money.
In order to turn things around, the Central Bank needs to not only pump up
but get the rate of income growth higher than the rate of interest on the
So, what do I mean by that? Basically,
income needs to grow faster than debt grows. For example:
let’s assume that a country going through a deleveraging has a debt-to-
income ratio of 100%.
That means that the amount of debt it has is the same as the amount of income the
entire country makes in a year.
Now think about the interest rate on that debt,
let’s say it is 2%.
If debt is growing at 2% because of that interest rate and
is only growing at around only 1%, you will never reduce the debt burden.
You need to print enough money to get the rate of income growth above the
rate of interest.
However, printing money can easily be abused because it’s so easy to do and
people prefer it to the alternatives.
The key is to avoid printing too much money
and causing unacceptably high inflation, the way Germany did during its
deleveraging in the 1920’s.
If policymakers achieve the right balance, a deleveraging isn’t so dramatic.
Growth is slow but debt burdens go down.
That’s a beautiful deleveraging.
When incomes begin to rise, borrowers begin to appear more creditworthy.
And when borrowers appear more creditworthy,
lenders begin to lend money again. Debt burdens finally begin to fall.
Able to borrow money, people can spend more. Eventually, the economy begins to
leading to the reflation phase of the long term debt cycle.
Though the deleveraging process can be horrible if handled badly,
if handled well, it will eventually fix the problem.
It takes roughly a decade or more
for debt burdens to fall and economic activity to get back to normal
– hence the term ‘lost decade.’
Of course, the economy is a little more complicated than this template
However, laying the short term debt cycle on top of the long term debt cycle
and then laying both of them on top of the productivity growth line
gives a reasonably good template for seeing where we’ve been,
where we are now and where we are probably headed.
So in summary, there are three rules of thumb that I’d like you to take away
First: Don’t have debt rise faster than income,
because your debt burdens will eventually crush you.
Second: Don’t have income rise faster than productivity,
because you will eventually become uncompetitive.
And third: Do all that you can to raise your productivity,
because, in the long run, that’s what matters most.
This is simple advice for you and it’s simple advice for policy makers.
You might be surprised but most people — including most policy makers — don’t pay enough attention
This template has worked for me and I hope that it’ll work for you.
