From scarcity to abundance

The road to prosperity

Until very recently nearly everyone lived in abject poverty. Most people had barely enough to survive. In 1651 Thomas Hobbes depicted the life of man as poor, nasty, brutish, and short. Yet a few centuries later a miracle had happened. Many people are still poor but more people suffer from obesity than from hunger while the life expectancy in the poorest countries exceeds that of the Netherlands in 1750, the richest country in the world in the wake of the Industrial Revolution.

In 1516 Thomas More wrote his famous novel about a fictional island named Utopia. Life in Utopia was nearly as good as in the Garden of Eden. The Utopians worked six hours per day and took whatever they needed. His book inspired writers and dreamers to think of a better world while leaving the hard work to entrepreneurs, labourers and engineers. Today many of us have more than they need but still we work hard and feel insecure about the future.

Why is that? The answer lies within the nature of capitalism. It is not enough that we just work to buy the things we need. We must work harder to buy more, otherwise businesses go bankrupt, investors lose money, and people will be unemployed and left without income. In other words, the economy must grow. That worked well in the last few centuries, and it brought us many good things, but it may kill us now.

People in traditional cultures didn’t need much. They were easily satisfied. Modern people in capitalist societies believe they never have enough. You can always go for a bigger house, a more expensive car, or more luxury items. Many of us do not need more but the advertisement industry makes us believe that we do. We believe in scarcity even when there is abundance. And so the economy must grow. That is what they tell us.

What are the consequences of this belief? If you eat too much this is great for business profits. And if you become obese as a consequence and need drugs for that reason, you again contribute to business profits so this is even better. Meanwhile we are using the resources of this planet in a much faster pace than nature can replenish. Humanity is standing before the abyss. Civilisation as it is will not continue for much longer. The end is near.

What has this to do with interest? If we want more products and services, we need more businesses, so we need investments. To do investments, we need savings. And to make people save, we need interest to make saving attractive. Consequently investments need to be profitable to pay for the interest. But there can be too much of a good thing. If we don’t need more stuff, we don’t need more savings, and interest rates go down.

A sustainable and humane economy?

Is it possible for humanity to live in harmony with itself and nature? We work harder than ever before and in doing so we destroy life on this planet. It seems hard to change this. If you organise production differently then your products might not be sold at a price that covers the cost to make them. In a market economy the value of a product is the price it fetches in the market. Marketing often comes down to inflating the market price of a product or a service to make more profit.

In the past there have been two fundamentally different approaches to the economy. For instance, before Germany became united in 1990, there were a capitalist and a socialist Germany. Socialist Germany ensured that everyone was employed. People in socialist Germany had enough but they had little choice as to what products they could buy. For instance, in socialist Germany there were two kinds of yoghurt while there were sixty in capitalist Germany.

And there was little freedom in socialist Germany. The secret police were everywhere. When Germany became united the socialist economy collapsed. Socialist corporations suddenly were bankrupt because no-one wanted to buy the products they produced. The ensuing reorganisation of the economy led to mass lay-offs and a staggering rise in unemployment. Ultimately 60% of the jobs in the former socialist firms disappeared.

Many lives and communities in former socialist Germany were destroyed. And people suddenly felt insecure about their future as businesses had to compete and make a profit in order to survive. In a market economy efficiency considerations determine what is produced. These efficiency considerations are the result of customer preferences as well as the requirement to make a profit. Loss-making businesses usually can’t attract capital in a market economy.

The quest for efficiency results in fewer and fewer people producing the things we need. To keep everyone employed in a capitalist economy unnecessary products and services must be produced, causing a rapid depletion of scarce resources as well as lots of waste. At least in theory we work can a few hours per day so we have more time for our mobile phone and each other. It may also be possible to free up resources to address poverty and other social problems.

And what has this to do with interest? The profit a corporation is expected to make should be higher than the interest rate in the markets for money and capital. Because what’s the point in making the effort and taking the risk of running a business if you can get the same return on a savings account? And so it appears that with negative interest rates corporations with zero profits can survive and that the economy doesn’t need to grow.

The road to inequality

Not so long ago an economist wrote a book that sent a shock-wave through the economic world because of stating a major cause of wealth inequality, which is that the return on capital usually is higher than the rate of economic growth. Capitalists reinvest most of their profits so capital usually grows faster than the economy most of the time. It can be proven beyond any doubt that capital can’t grow faster than the economy forever. Something will have to give at some point.

And what has this to do with interest? Interest is any return on capital. Interest income is the income of capitalists. That includes business profits and interest on bonds. The graph shows that labour income as part of the economy has diminished in recent decades in the United States. And that is because the capital share of national income has risen. In the past depressions and wars destroyed a lot of capital. Since 1945 there hasn’t been a serious depression or a world war.

The capitalist economy is like a game of monopoly. First everyone is doing great and capital is built in the form of housing and hotels. At some point some people can’t pay their bills anymore. To keep the game going, the winners can lend money to the losers. But at some point the losers can’t pay the interest any more. To keep the game going, interest rates must be lowered, so they can borrow more. But at some point some people can’t pay the interest again.

This happens in the real economy too. In a game of Monopoly we can start all over again. In the real economy that’s not an option. It would mean closing down factories in another great depression or destroying houses in another world war. So the game must continue. In Monopoly the rich can lend money at negative interest rates to the rest so that they can pay their bills. In the real economy this may be possible too.

Monopoly features a scheme that looks like a universal basic income. Every time you finish a round you get a fixed sum of money from the bank. At some point the bank may end up empty. The rich can then lend money to the bank at a negative interest rate to pay for it. It might seem a stupid thing to do because Monopoly is just a game. But the real economy is not. It may need an income guarantee for everyone financed by the rich.

An outline of the future economy

Can we have an economy that is humane and in harmony with nature? A few centuries ago no-one would have believed that we could live the way we do today and most people would have believed that it is more likely that unicorns do exist. If excess resource consuming consumption is to be curtailed, fewer options for consumers remain, for instance there may only be organic products, and supermarkets in the future might look a bit like those in former socialist Germany.

That may not be so bad. People in socialist Cuba live as long as people in the United States despite the United States spending more on healthcare than any other country in the world. Cubans eat no fast food so they live a healthier life style. And Cubans suffer less from a negative self image than people who are exposed to the advertisement industry. Advertisements aim to make us unhappy with ourselves and what we have in order to make us buy more products and services.

Like in former socialist Germany there isn’t much freedom in Cuba. If the government is to regulate the fat content in fast food or the sugar content in sodas then we lose our freedom to become obese. There may soon be illicit markets for those products as there are already illicit markets for crack cocaine. Alternatively, the government could even end our freedom to destroy life on this planet and kill our children. That might be oppression. But the alternative may be a collective suicide of humanity.

It is bad for economic growth. If the most resource consuming non-essential activities are to be axed, entire industries will be wiped out like in socialist Germany. One can think of making air travel sustainable and what that will with ticket prices. Many people will not like this. Still, life in a future sustainable market economy can still be far more agreeable than life in Cuba or former socialist Germany.

So what has this to do with interest? Change may cause a massive economic shock like the Great Depression. But the economy may soon recover if interest rates can go negative. Before you say that it is more likely that unicorns do exist, the idea has already been tested during the Great Depression. The outcome is dubbed the Miracle of Wörgl. And evidence for the existence of unicorns has not yet been so forthcoming.

If interest rates are low then the creators of ideas and makers of things are rewarded more. They are the entrepreneurs and labourers rather than the owners of capital. It is in the spirit of Silvio Gesell who believed that labour and creativity should be rewarded and not the passive ownership of capital. Only when there is a shortage of capital or more demand for goods and services than there is supply, people need to be encouraged to save.

The economy is already constrained by a lack of demand rather than supply. That will be even more so when excessive consumption is to be curtailed and the rich have fewer options to spend their money on. And so it may become possible to fund an income guarantee with income taxes as well as negative interest on government debt. This can improve the bargaining position of labourers.

It is better to have an income guarantee rather than a universal basic income because that would be cheaper. There is little to gain from handing out money to people that already have enough. And the scheme should provide an incentive to work. A simple example can explain how that might work out. Assume there is an income guarantee of € 800 per month and a 50% income tax. The following table shows the consequences for different income groups.

Perhaps it doesn’t feel right that people are being paid for doing nothing. But nowadays people are paid for producing and selling things we do not really need and by doing so they endanger our future. Someone who does nothing at all can be worth much more for society than a travelling salesperson, a trader on Wall Street or a constructor who builds mansions for the rich. Of course it is better that people do something useful and useful people should be rewarded for their efforts, but doing nothing is always better than doing something stupid, and having zero value is always better than having negative value.

Another question is how this can be paid for? The Miracle of Wörgl shows us that the economy can flourish without growth when interest rates are negative so that most people will be employed. Money can still be a motivator to run a business or to go to work but less so than in the present. It doesn’t have to stop people from starting a business. Many entrepreneurs didn’t intend to become rich. They just wanted to be an entrepreneur or believed in the product they were making or selling. Still, there is no doubt whatsoever that a humane economy in harmony with nature will be very different from the economy of today.

Why all interest is usury

In the past when borrowers couldn’t pay their debts with interest they became the serfs of money lenders. That’s why interest was often forbidden and called usury. Most people have forgotten about that. But nowadays most money is debt on which interest must be paid. And that is the reason why there are so many problems in the financial system like instability, increasing debt levels, inflation, and central banks having so much power.

Incomes fluctuate but interest payments are fixed. And interest is a reward for risk. So the less a debtor can afford to pay interest, the higher the interest rate will be. The lender is rewarded with a higher interest rate to take that risk. It is therefore not surprising that the financial system is unstable.

Even more importantly, money is loaned into existence and must be repaid with interest. So if the interest rate is 5% and there is € 100 in existence then € 105 must be returned after a year. But where does the extra € 5 come from? There are a few options:

  • Lenders spend some of their balance so borrowers can pay the interest.
  • Some borrowers default so a part of the balance is not returned.
  • Borrowers borrow more.
  • The government borrows more.
  • The central bank creates the shortfall out of thin air.

All these things happen and often at the same time. Lenders on aggregate let their capital grow at interest. A few defaulting borrowers are acceptable but too many defaults can easily cascade into a financial crisis and create an economic crisis. The cost of letting the financial system fail is so big that this option is not acceptable. So if no-one else is willing to borrow then the government or the central bank steps in.

That’s why debts continue to grow. That’s why there is inflation. That’s why we have economic crises. That’s why governments are running deficits. That’s why there are financial crises. That’s why we need central banks to save us. That’s why all fixed positive interest rates on money and debts are usurious, even when they are low. The following example can demonstrate that.

Suppose that Jesus’ mother had put a small gold coin of 3 grammes in Jesus’ retirement account at 4% interest in the year 1 AD. Jesus never retired but he promised to return. Suppose now that the account was kept for this eventuality. How much gold would there be in the account in 2020? The answer is an amount of gold weighing 12 million times the mass of the Earth.

A mere 4% yields an incredible amount of gold after 2020 years. Someone has to pay the interest, in this case the people who borrowed money from the bank. If Jesus doesn’t come back to spend his money, that’s impossible. At some point the debtors can’t pay the interest, let alone repay their debts. They can only borrow more or default. Lowering the interest rate doens’t solve the problem. It only postpones the reckoning.

Ending usury by banning interest was never possible. Lending and borrowing would stop or go underground. The capitalist economy requires lending and borrowing so without interest it would never have been possible to build a modern capitalist economy. But interest rates are poised to go negative so it may soon become possible.

Natural Money is interest free money with a holding fee. The holding fee on money makes it attractive to lend out money at negative interest rates. For example, if the holding fee is 10%, lending out money at an interest rate of -2% will save you 8%. Once most interest rates are negative, positive interest rates can be forbidden. That can end reckless lending without producing a financial or economic crisis.

What does ending usury mean? Interest is everywhere. Interest is hidden in taxes, rents, the price of all the products and services you buy. Most pay more interest than they receive. Ending interest will benefit most people as 90% pays interest on balance while only the to 10% richest people receive interest on balance. But there is more to it. A few consequences:

  • You can’t borrow if your finances are in dire straits. Lending money to people in financial distress shouldn’t be left to the markets.
  • People and businesses will become less leveraged as there is no incentive to that. Risky ventures will be financed with equity.
  • The business for banks does’t change much. Borrowing money at -2% to lend it at 0% is as profitable as borrowing money at 2% to lend it at 4%.
  • Financial engineering will be reduced as financial engineering schemes like LBO’s often involve great leverage.
  • The economy can find support in the negative interest rate so governments don’t need to go into debt to stimulate the economy.
  • The maximum interest rate can curb debt creation for as soon as the economy recovers equity investments become more attractive relative to debt.
  • It can be a blow to political corruption because borrowers need to be trustworthy, and that includes governments, so taxes must cover government expenses.
  • This is not austerity as governments don’t pay interest on their debts but instead receive interest on their borrowings.

Ending interest reduces leverage and this can stabilise the financial system and the economye. The holding fee can ensure that the economy will flourish. Money with a holding fee has brought the economy of the Austrian town of Wörgl back to life in the midst of the Great Depression. Ancient Egypt had a financial system with this money for more than 1,000 years. Usury can end very soon and it may never come back.

A tenner on the street

A tenner on the street

There is no such thing as a free lunch

This is just another joke about economists. Suppose you just have found a tenner on the street. You are very excited about this windfall so you feel the urge to tell the next person you meet about your find. Now suppose that this person happens to be an economist. And you say: “I just found a tenner on the street.” What do you think the economist will reply? He or she would probably say: “That’s impossible. If there really was a tenner on the street then someone would have picked it up already.”

“There is no such thing as a free lunch,” is another saying that means more or less the same. Of course there are people who get a lunch for free but in that case someone else has to pay for it, just like someone else has paid for the tenner. According to economics it is impossible to get money for free, and if it is possible then someone will take it as soon as it is there, so there is no money for free for long. But why is this important? If a government makes a law it should not ignore this effect in markets.

Economists call it arbitrage

Assume that gold costs € 50 per gram in France and € 40 per gram in Germany. What will happen? There is money to be made by buying gold in Germany and selling it in France. Hence demand for gold in Germany will go up as will supply in France. According to the law of supply and demand, the price goes up when demand increases and the price goes down when supply increases, so the price in Germany goes up and the price in France goes down until the price is the same in both countries. Economists call this arbitrage

Smuggling is more or less the same. Cigarettes are more expensive in the United Kingdom than in the rest of Europe. There is money to be made by smuggling cigarettes into the United Kingdom and selling them there illegally. The price difference promotes the smuggling. If a government introduces legislation that affects the price of goods and services it should take into account that their measures can illicit smuggling and black markets. The difference between arbitrage and smuggling is that arbitrage is legal.

That’s also why it is so hard to end smuggling. If cocaine costs € 10 per gram in Colombia and € 70 per gram in the United States, there is a lot of money to be made in the trade. That’s why the War on Drugs is a failure and why there is so much violence in South America. It may be better to regulate lesser harmful drugs like canabis in the way it is done with alcohol and cigarettes. The use of harmful drugs could be seen as a medical issue and addicts could be helped rather than left on the streets. It was also a reason to deregulate financial markets. It would be hard to end gold smuggle if there are price differences between countries.

The essence of trade

A tenner is more likely to be found in places where others don’t look. That’s why Wall Street firms hire the brightest minds on the planet to find these places. For instance, Apple stock may be for sale for € 150 in Australia while in Germany the stock is doing € 151. And you must be faster than everyone else once there is a tenner on the street if you want to be the one who picks it up. Hence, Wall Street firms pay huge sums of money to have the fastest computers and networks.

So once a tenner falls out of your pocket, Wall Street has already picked it up long before it hits the street. They may even look inside your pocket and pick the tenner before it falls. So if you try to sell your Apple stock for € 150 and someone else is willing to pay € 151, Wall Street banks with their fast computers and networks snatch away the stock you offer for € 150 and immediately sell it to the other person for € 151.

You can call this theft but it is the essence of trade. The ancient Greeks already knew this. Their god for the traders was also the god for the thieves. Trade sometimes coincides with questionable ethics and the difference between trade and theft is sometimes obscure. But trade is useful. It performs the following functions in society:

  • Goods are produced in one place and consumed elsewhere so trade bridges distance.
  • Goods are produced first and consumed later so trade bridges time.
  • Goods are produced in certain quantities and demanded in other quantities so trade matches volume.

Trade is about information. A successful trader has better or more timely information. For instance, if you know that a product is successful before others know it, you can buy the stock of the corporation making the product before others do and make a profit by buying the stock cheap and selling it at a higher price. Financial markets are riddled with schemes like that. A way to combat theft disguised as trade is to make markets more transparent, which more or less means that everyone can have the same information at the same time, which more or less means that there will never be a tenner on the street just like the economist says.

Carry trade

Tenners can be found on other places too. If the interest rate in one country is lower than in another country, you can make a profit by borrowing money in the first country lending it in the second country. Economists call this a carry trade. You might expect that like the price of gold, interest rates would converge, but that doesn’t always happen because most countries have their own currency. For instance, interest rates in Japan have been near zero for decades while they were higher in the rest of the world, so there was a massive borrowing of Japanese yen. These yen were exchanged into other currencies and lent at higher interest rates.

It is attractive to borrow yen at 1% and lend dollars at 5% and pocket the difference. Normally this difference would not exist for long because the interest rate in yen would rise because of the demand for borrowing in yen. But the Japanese government didn’t allow this to happen. The central bank kept on lending yen at 1% because the Japanese economy was slow and there was no inflation. The Japanese government didn’t like the yen to rise because that would hurt their exports so they allowed it to happen. The carry trade has been very profitable for bankers around the world for nearly two decades. In a sense the Japanese central bank was throwing away massive amounts of money, but not on the street.

Throwing money at the banks

Government and central bank interventions in the markets like setting interest rates have undesired side-effects. Central banks are throwing money around and much of it ends up in the pockets of bankers. Somehow this appears to be necessary. That is because most money is debt created by banks. On this debt interest must be paid. So if you borrow € 100 and the interest rate is 5% you have to return € 105 after a year. But where does the extra € 5 come from? Here are the options:

  • Someone else is going to borrow € 105 so you can repay you loan.
  • You are not going to repay your loan (in full).
  • The government is going to borrow the extra € 5.
  • The central bank prints the € 5 out of thin air.

Usually these things happen at the same time. If people do not borrow enough, other people can’t repay their loans, banks go bankrupt and a lot of people lose their money, so governments step in and borrow. And if no-one is willig to lend to the government anymore, central banks create money out of thin air. Letting things crash isn’t an option. That could result in an economic depression. And an economic depression is very, very bad.

The prospect of a an economic depression scares the hell out of central bankers. And so they are throwing money at banks to fix any serious shortfall that might occur, usually before it materialises. The extra € 5 has to come from somewhere. So if no-one goes into debt to pay for the interest then the central bank feels obliged to create the € 5 out of nothing. That’s why central banks are called the lenders of last resort. They exist to save the economy from the banks and their scheme of usury and in doing so they save the banks and their scheme of usury. On the bright side, ending usury might solve these problems, perhaps once and for all.

Clutching at a straw

When I was eighteen years or so I once read The Limits of Growth. That’s depressing stuff, most notably if you’re young and expect to live for another sixty years or so. Doom seemed imminent and I would probably live to see it happen. That was the moment when my views about the future turned grim. Before that I hardly had views about the future at all. A few years later I became an environmentalist and a member of Friends of the Earth in Groningen. Friends of the Earth does research and tries to convince people that they should change their lifestyles. Friends of the Earth also lobbies with politicians and pressures corporations. And sometimes we protested.

One day we blocked the entrance of Groningen Airport to protest against the government subsidies for the airport. The city council felt that Groningen needed an airport but Groningen wasn’t big enough to make it profitable. When we were sitting there, the police came to remove us, and it suddenly became clear to me that activism didn’t help. Politicians will be voted out of office when they are serious about solutions. Businesses will go bankrupt if they take appropriate action unless all other businesses do the same. The required measures are extremely costly and will affect our lifestyles so profoundly that it would never happen in the current political and economic system.

Once being over a cliff, a cartoon character can only clutch at a straw. And only in cartoons the straw might hold. Friends of the Earth in Groningen worked together with the Strohalm Foundation. The meaning of the Dutch word strohalm is straw. According to Strohalm, the economy must grow because of interest, and that’s destroying the planet. It is ‘grow-or-die’ because interest rates need to be positive. Any solution begins with ending interest, they believed, and interest causes a lot of other problems too, like poverty and financial instability. Strohalm’s idea was banning interest and charging a fee on money as Silvio Gesell had proposed, so that it would be attractive to lend out money without interest.

Economists didn’t take interest-free money seriously. If you can receive interest elsewhere then why would you lend out money without interest? And if you can borrow money at an interest rate of zero, you would borrow as much as you can and put it in a bank account at interest. Therefore, interest-free money with a holding tax would never work, at least so it seemed, and it didn’t take long before I realised that too. Only, that wasn’t satisfactory. Accepting doom is like committing suicide. If interest is the root of many social and environmental problems, and may destroy human civilisation, you can’t ignore that. And perhaps it could work. During the Great Depression it had been tried in a small Austrian village and it was a stunning success.

For years I used public transport as much as possible, but at some point I began to realise that it was all pointless. More and more people started driving SUV’s. They didn’t care. It didn’t matter what I do. A car can make your life more comfortable and I had no higher morals than other people.

A few years later, in 1998, I became a freelance IT specialist. I made a lot of money so I had money to invest. My first investments were small and not very successful. That was because I believed that the profits of corporations matter. But investments in loss-making internet startups did very well while profitable corporations did poorly. And so I came to believe that I had to stay informed about the developments in the financial markets. In 2000 I joined the investment message board Iex.nl.

On the message board was a day trader who shared all kinds of conspiracy theories with us. For instance, if the markets were about to collapse, a secret group called Plunge Protection Team would come to the rescue. He was ridiculed, but after the internet bubble popped, markets often miraculously recovered when they were about to crash.

And gold often crashed because of sudden selling. The day trader believed central banks wanted to keep confidence in their currencies. If the gold price were to rise, he claimed, people would lose trust in central bank currencies. This was new to me, and probably it wasn’t true, but I already had bought some gold because I didn’t trust financial markets and the people operating them. I was not good picking stocks, and I was too risk averse to be very successful in the stock market, but the gold turned out to be a good investment as I held on to it for decades.

In 2001 after the Internet bubble had popped I pitched the idea of interest-free money on the message board. My lack of knowledge was eclipsed by my zeal and lengthy discussions followed. On the Internet people from different backgrounds and different knowledge can be in one virtual room and participate in a discussion. I was rebutted time after time, but as these discussions went on, my knowledge of the financial system increased and I became aware of the issues that had to be resolved in order to make interest-free money work.

As a gold investor I became familiar with the Austrian School of Economics. This group questions money creation by banks and the need for central banks. They pointed at the inflation caused by money creation and central banks. At some point all the debt banks create would eventually collapse the financial system and money would be worthless, they believed.

And so two opposing fringe ideas, interest-free money with a holding tax and Austrian School, were challenging each other in my mind, which may be how Hegelian dialectic is supposed to work. In 2008 this resulted in a resolution and the idea of Natural Money was born. The economy can do better without interest so returns for investors can be higher. As positive interest rates are not allowed, the money may rise in value, so that interest-free money can give better returns. Hence, interest-free money was possible, perhaps even inevitable. In the following decade I integrated modern main stream economics into the theory of Natural Money. This research can be found on the website Naturalmoney.org.

The future of interest rates

There is a relationship between the amount of capital in a market economy, wealth inequality, savings, the level of debt, and interest rates. If an economic depression or a world war can be avoided, this relationship may decide the future of interest rates, and interest rates may go negative. If this makes you yawn, you have read the message already, and you can proceed with more exiting ventures like checking out what your friends are doing on Facebook or Instagram.

If instead you are thrilled by the idea of knowing more about this relationship, you may continue reading. Interest rates are the result of supply and demand for money and capital. Money and capital differ from consumer goods like coffee and services like haircuts. Money is a medium of exchange. You use money to buy and sell consumer goods and services. And capital isn’t consumer goods or services either. Capital is used to make these consumer goods and services. Hence supply and demand for money and capital need a separate explanation.

The price of money

A kilogram of coffee might cost € 7 in France and $ 8 in the United States. But what does that mean? Is coffee more expensive in the United States than in France? That entirely depends on the price of the dollar and the euro. If one dollar is worth € 0.80 then $ 8 is € 6.40, which is less than € 7. The price of the euro and the dollar change every day because of changes in supply and demand in the market for euros and dollars. But the price of euros and dollars is not the price of money, at least according to economists.

When economists talk about the price of money, they do not mean the price of dollars and euros. They talk about the interest rate. The supply and demand for money and capital determine the interest rate, hence the interest rate is the price of money. This price has a relation with the returns on capital because investments in capital are an alternative to lending. Money isn’t produced and consumed like coffee. If you borrow money, you may have to return it with interest. Borrowers may pay for the use of money, not for the money itself.

There are people and corporations that have savings as well as people and corporations that need money for consumption or investment. So there is supply and demand for money. But what determines the supply and demand for money and therefore the interest rate? It begins with the choice people have when spending their income. They can choose between consumption and saving. Savings can be used for investments in corporations to make products and services in the future.

Consumption versus investment

Economists sometimes use a simple model consisting of only households and businesses to explain things like consuming and saving. Households consume the stuff businesses make. In order to make that stuff, businesses need investment capital provided by households from their savings. It is important to notice that some households borrow and some businesses save, but on balance households save while businesses borrow to invest.

Households can do two things with their income. They can either use it for buying stuff, which is consumption, or save so that businesses can invest. For example, if you are a plumber and need to buy a new van for your business, which is an investment, you may have to forego a new car for your family, which is consumption, to save money for the van. You could also borrow the money for the van so that you can buy the family car too, but in that case someone else has to save so that you can borrow.

If people spend a lot of money on consumption, businesses sell a lot of stuff and make great profits. Businesses may be willing to invest so that they can sell even more and make even more profits. But if there are only a few savings because people spend a lot of money on consumption, so businesses might fear they can’t borrow and may be willing to pay higher interest rates, so that interest rates go up.

When interest rates go up, some businesses may abort their investment plans as they don’t expect to make enough money to pay for the interest. At the same time, more households may be willing to save. So when interest rates go up, the demand for money goes down and the supply of money goes up.

On the other hand, if households save a lot of money and do not consume, there are a lot of savings, but businesses are not willing to invest because they have trouble selling stuff and making profits. In that case households fearing that they don’t receive interest on their savings are willing to lend at lower interest rates, and interest rates go down. But how do households choose between consuming and saving?

Time preference

Economists believe that your choice between saving and borrowing depends on your time preference as well as the interest rate. Time preference is your willingness to forego your needs or desires in the present in order to fulfil your needs or desires in the future. An example can illustrate this. Assume that you want to buy a new car. You want that new car now but you don’t have the money. You can either wait and save to buy the car later or you can borrow to buy the car now.

Assume the car costs € 10,000. If the interest rate is 10%, you may realise that borrowing money to buy the car will cost you dearly. If you pay back € 1,000 each year, you repay the loan in 10 years. Over that period you pay € 5,500 in interest so the car will cost you € 15,500 instead of € 10,000. The alternative is to wait and save money to buy the car.

If you can manage saving € 1,500 per year and the interest rate on savings is also 10%, you could buy the car after less than six years. But then the car only costs you € 8,250 because you receive € 1,750 in interest. At an interest rate of 10% borrowing money to buy this car costs nearly twice as much as saving.

That may convince you to save and drive your old car for six more years. If the interest rate is lower, you may find borrowing more attractive than saving because you would rather have the new car now. Your time preference tells how strong your desire is to have the car now rather than later. It determines the interest rate you are willing to pay. Not surprisingly, different people have different time preferences.

Time preferences affect interest rates. Suppose that you want to borrow money for a new car. Suppose that you can only borrow the money from John. John has € 10,000 but he wants to buy a car too. Time preferences are going to decide whether or not John is going to lend you this money. If your time preference is 7% and John’s time preference is 5%, he will keep his old car for a while and lend the money to you. He may do this because he expects to buy a bigger car once you have repaid your loan with interest.

The interest rate could be anywhere between 5% and 7% depending on your and John’s negotiating skills. You won’t borrow at interest rates above 7% and John won’t lend at interest rates below 5% but any interest rate between 5% and 7% is acceptable to both you and John. In this way time preferences affect interest rates.

When interest rates go down, more people may borrow and fewer people may save because of their time preferences. If the interest rate is 4%, John may buy that bigger car now and borrow the money to buy it. If the interest rate is 8%, you would save to buy the car. When interest rates rise, more people may opt for saving instead of borrowing. The interest rate may move to where supply equals demand, which depends on the time preferences of lenders and borrowers but also on the demand for investment capital.

Capitalist spirit

Time preference only works for ordinary people. There are other people too. They are called capitalists. You probably have heard about them. Capitalists think differently. They suffer from a condition called capitalist spirit, which is having little or no time preference. Capitalists think that money spent on a frivolous item is money wasted, because when you invest your money, you end up with more money that you can invest again.

Capitalists save regardless of the interest rate. They rather invest in the distant future when they are dead than spoil their money on frivolous items during their lifetimes. Consequently capitalists end up with a lot of money when they die. What’s the point of that? Capitalists invest in businesses that make the frivolous items ordinary people enjoy. Ordinary people wouldn’t have invested their money, but spent it on frivolous items instead so that these items wouldn’t have been produced in the first place.

Perhaps you think that all capitalists are wealthy. But that isn’t true. Anyone who saves as much as he or she can regardless of the interest rate can be called a capitalist. What is important here, is that the capitalists as a group own most capital, and because capitalists own so much money and capital, and keep on saving and investing, there is a surplus of savings. And if there is a surplus of savings at an interest rate of zero, the interest rate should be negative according to the law of supply and demand.

Convenience

When you lend money to someone else you can’t use it yourself. There may be a new mobile phone you want to buy, but alas, you have lent out your money. This is not convenient. But then you remember with a smile on your face that you will be able to buy the phone but also an additional hip phone cover next year because you receive interest on that loan. So, if you don’t receive interest on your money, you may not bother lending it out because you may suddenly need it. Interest rates on long-term loans are higher than interest rates on short-term loans because the longer you can’t use your money, the less convenient it is.

When you deposit money at a bank, you lend it to the bank but you can still use it any time. That is possible because when you make payment, for example for legal advice, this money ends up the account of the lawyer. The bank will then be borrowing this money from the lawyer instead until she uses it to pay someone else. This is convenient so you are willing to lend money to a bank. For that reason interest rates on current accounts and checking accounts are low. Having money in a bank account is more convenient than cash so the bank may even charge you for having an account.

Risk

Lending out money can be risky. There are two types of risk. First the borrower may not pay back the loan. That could make you reluctant to lend. So if someone of questionable integrity wants to borrow money from you, and you fear that she may not pay back, she could offer you a very high interest rate so that you might think, ‘Well, she may not pay back, but the interest rate is very attractive, so I’ll take my chances and do it anyway.’

Second, money may become worth less in the future. This is called inflation. If there’s a lot of inflation then the money that buys a mobile phone today may only buy a phone cover next year. In that case you may spend your money right away on a mobile phone before it is too late. That is unless someone wants to borrow the money from you and offers a very high interest rate, so that your can buy a better model next year.

The business of a bank is to know its customers. For that reason lending money to a bank is less risky than lending out money to an individual or a corporation. And because banks are supposed to be good at managing risk, they can borrow at lower interest rates, meaning that interest rates on bank accounts are lower than those on loans.

And because banks know their customers and lend to many different people, they can manage risk better than you can and lend at lower interest rates than you are willing to because if you lend money to a someone you don’t know, you may desire a higher interest rate because you don’t know whether he or she is going to repay the loan.

Returns on investments

If you have money, you could invest it in corporations or real estate. Corporations pay dividends and real estate pays rent. If the rents and dividends are higher than the interest rate you get by lending out your money, you may prefer investing to lending. But investing is more risky than lending. If sales are sluggish, profits may go down and dividends may be cut, but lenders still get their interest. Nevertheless investments are an alternative to lending, so if investments offer better yields, you may opt for investing.

If someone wants to borrow money from you, the interest rate must be high enough otherwise you may invest this money instead. Other people who have money are in a similar position. Borrowers need to offer attractive interest rates in order to be able to borrow. Similarly, if dividends and rents are low, people with money may prefer lending to investing, so that borrowers can negotiate lower interest rates. In this way the returns on investments affect interest rates on loans.

The type of money used

The properties of money can affect interest rates. Just imagine that apples are money and you are saving to buy a house. If someone wants to borrow 1,000 apples from you, and promises to repay those 1,000 apples after 10 years when you plan to buy your house, you would gladly accept this generous offer. You may even accept an offer of 900 apples because that is better than letting your apples rot. In this case you would settle for a negative interest rate. But you would only do so if there are no alternatives.

If you could make 10% per year in the stock market, you could exchange your apples for Apple stock because their gadgets are in great demand and outrageously expensive. In that case, it doesn’t matter that apples rot and you could demand interest on a loan. But if returns on the stock market are low or when stock prices are fluctuating so wildly that you can’t sleep at night, you may prefer the offer of 900 apples.

If the money had been gold, you would never accept such an offer, even when the stock market is doing terrible. You can always keep your gold in a safe deposit box. Similarly, you wouldn’t accept negative interest rates on euros or dollars because you can take your money from the bank and store the bank notes in a safe deposit box. The problem with this is that if you put money in a safe deposit box, other people can’t use it for buying and selling stuff. And this can cause an economic depression.

Central banks

It is often said that central banks set the interest rate. But how do they do that? Central banks can print money. If central banks believe that the interest rate is too high, they print more money so that there is additional supply and interest rates go down. On the other hand, if central banks believe that the interest rate is too low, they print less money so that interest rates go up. If the central bank says that it sets the interest rate to 3%, this means that it will print precisely enough money to keep the interest rate at 3%.

Why do central banks print money? Money isn’t produced and consumed like coffee. If you borrow money, it has to be returned with interest. Most money is debt so where does the interest come from? Capitalists let their money grow on their bank accounts so the money to pay the interest from must come out of thin air. Individual borrowers may be able to repay their debts with interest but on aggregate borrowers can’t.

More money needs to be borrowed to pay for the interest. That’s why the total amount of debt increases each year. And if people aren’t borrowing enough, the central bank may print more money to prevent a financial crisis.

Sometimes people don’t borrow enough to keep the economy going and sometimes they borrow too much so that the economy is overheating. Central banks adapt their money printing to prevent these things from happening. Central banks raise interest rates and print less money (or stop printing money or even destroy money) when they want people and businesses to borrow less and they lower interest rates and print more money when they want people and businesses to borrow more.

The future of interest rates

Interest rates went down because capitalists acquired more and more capital over the years and kept on saving and investing regardless of the interest rate. In the past returns on capital have mostly been higher than the economic growth rate while most returns were reinvested so that a growing part of total income was for capitalists. As capitalists reinvested most of their capital income, this is not sustainable in the long run.

Capital income (red) versus total income with capital income growing faster than total income

The graph above shows how total income and capital returns (in red) develop if the economic growth rate is 2%, the return on capital is 5%, capital income starts out as 10% of total income, and all capital income is reinvested. After 25 years the economic pie has grown faster than interest income and more is available for wages. At some point interest income starts to rise faster than total income, and less becomes available for wages. And after 80 years there’s nothing left for wages.1

This graph explains a lot about what is going on in reality. When wages started lagging, people couldn’t afford to buy all the stuff corporations made. As a consequence business profits, which is capital income, went down. In the short run it was possible to prop up business profits by allowing people go into debt to buy more stuff. But at some point people couldn’t borrow more unless interest rates went down. As capital income went down, capitalists became willing to lend money at lower interest rates, allowing people to borrow more to buy stuff. As interest rates went lower, more and more people went into debt because interest rates moved below their time preferences.

Nowadays most people are borrowing from the capitalists, for instance via mortgages, car loans, and credit cards, but also via governments as governments borrow from the capitalists too. Many people and governments can’t afford to borrow more. Interest rates are already near zero and may need to go negative if the law of supply and demand is going to do its job. In that case capitalists may start handing out money to the rest of us so that we can keep on buying the stuff their corporations make.

Capitalists may only lend at negative interest rates if money is like apples and not like gold.2 When interest rates are negative, people may buy land or real estate so that the prices of these properties may rise. Property taxes are often based on the value so properties may become less attractive at higher prices. Alternatives are gold or bitcoin, but at some point gold or bitcoin may become so expensive that the risk of losing money on these investments could deter people from buying more. Nevertheless, these alternatives put a constraint on how low interest rates can go. Interest rates must remain attractive for investors.
