A brief history of money

The following is an extract from the unpublished book:

Peoplons, Charmons and the Strange One: the uncertain science of economics

by C. S. Adams, Illustrated by Cohenbaum.

Tokens of exchange:

In the economist’s book of myths and legends, money was invented to solve the “double coincidence-of-wants” problem in a pair-wise economic exchange. Paul the baker wants a beer, but Mary the brewer already has a loaf of bread. Instead Paul gives Mary some gold coins or tokens which are exchangeable for something else later on. Problem solved.

The key property of a coin is not its intrinsic value – over time, gold was replaced by cheaper metals or pieces of paper. The key property is that the token is likely to be accepted as a unit of exchange for subsequent transactions. As Adam Smith writes in the Wealth of Nations, Book I, Chapter 4, Of the origin and use of money:

 … every prudent man in every period of society, after the first establishment of the division of labour, must naturally have endeavoured to manage his affairs in a such a manner as to have at all times by him, besides the peculiar produce of his own industry, a certain quantity of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for the produce of their industry.

Smith goes on to explain why metals are a convenient substance for this exchangeable commodity:

Metals can not only be kept with as little loss as any other commodity, scarce anything being less perishable that they are, but they can likewise, without any loss, be divided into any number of parts, as by fusion those parts can easily be reunited again; a quality which no other equally durable commodities possess, and which more than any other quality renders them fit to be the instruments of commerce and circulation.

Although metals are a ‘convenient’ representation of the unit of exchange they are not necessary. In fact, it makes no sense to limit economic activity to the availability of a particular metal whose supply is limited. The double-coincidence-of-wants problem could just as easily be solved using any accepted token (see e.g. David Graeber‘s brilliant Debt: the first five thousand years). In the medieval era, when Paul the baker is served a beer and does not have anything to offer in exchange, he signed Mary’s book of accounts, or made a mark on a tally stick. After the beer is brewed and consumed, all that remains is a mark on a stick which records who made the beer and who drank it – a collective memory of credit and debt. The stick is split in two – a stock and a foil – such that both Paul and Mary have matching records. As they are a record of a debt, they acquire a value and may be accepted in exchange by a third party if everyone believes that one day Paul will pay. At the end of the year, Paul and Mary and everyone else tally up their stocks. By storing information about an unbalanced exchange, the tally sticks – something readily available with no prior value – become valuable, they become money.

A sculptural tribute to the historical significant of tally sticks can be found on the gates of the UK National Archive in Kew, near London. The tally stick model illustrates how money functions as information about an unbalanced pair-wise exchange where a good only went one way.  Money is simply a collective memory recording the fact that the balance of the original pair-wise exchange remains to be restored – it is a collective memory of a credit-debt relationship. Although this simple model can function at the level of a village where everyone knows Paul, scaling up to a whole country requires some additional structure. Fiat money is the modern equivalent of tally sticks – based on computers rather than pieces of wood and with an extra layer of institutional organisation. But just like tally sticks, fiat money has no intrinsic value – it’s utility is based on belief.

From tally sticks to Sovereign money:

At various points in history, the Sovereign took a particular interest in money in order to further their goals such as the conquest of new lands.

With assistance from the smartest guys in the room, the Sovereign concocted a money circuit to finance overseas adventures. In its simplest form the story goes like this: First, the Sovereign mints metal coins – Sovereign money – with the King or Queens head embossed on one side. This Sovereign money is used to pay soldiers that participate in the military campaign. In return for protecting citizens from foreign invaders, the Sovereign demands a tax to be paid in Sovereign money. The soldiers are the key link in the circuit. Someone in the family or community has to go and fight to ensure that the community has enough Sovereign money – effectively a tax credit – to pay the Sovereign’s man. When a soldier returns from war and offers a Sovereign coin in exchange for Mary’s beer or Paul’s bread they are more than pleased to accept, knowing that one day the tax man will call.

The invention of Sovereign money – the government’s spend and tax circuit – sold itself on the basis of security. It is not that different today. For the Sovereign’s spend and tax circuit to work, it needs to be carefully controlled –  alternative circuits break the loop and could undermine the value of Sovereign money. To function effectively there needs to be monopoly control of the money system. Although, the Sovereign’s Exchequer initially accepted payment in the form of tally sticks this creates complications – if taxes are paid in tally sticks there is no incentive to join the army and the primary money circuit is undermined. Their use was eventually banned in 1826. As part of Pitt the Younger‘s reforms of the money system, the office of the Exchequer was abolished on October 10th, 1834. Six days later government officials, decided to burn their stock of tally sticks and set fire to the Houses of Parliament. This event is recorded in two paintings by Joseph Mallord William Turner (London 1775–London 1851) that epitomise the Turner style. If you happen to be in Cleveland or Philadelphia you can see the originals.

From gold to fiat:

Throughout history there was a feeling that money should be linked to something substantial and durable, for example, a precious metal. At various times, a gold exchange standard was adopted and then abandoned.* After the second world war, the Bretton Woods system pegged most major currencies to the dollar which in turn was exchangeable for a particular quantity of gold – 35 US dollars per ounce. The gold standard locks national economies to a fixed exchange rate which can become too restrictive as their economic paths diverge. The gold standard was temporarily suspended by Nixon in 1971 and collapsed completely in 1973. Over the longer term it makes no sense to link the quantity of money to the quantity of any particular metal, or to tie different economies to a fixed exchange rate. After 1973, all money became fiat (let it be) money, whose value is based on confidence alone. Modern fiat money is like tally sticks except now the state has monopoly control over the creation of new money.

There is no particular evidence that either commodity money or fiat money has a particularly strong influence on trend growth, however, the switch from a gold standard to fiat money is fundamental, and part of the turmoil of the 1970s was a coming to terms with this. In the post Bretton Wood era, there is nothing to limit money creation apart from maintaining confidence in the unit of exchange – the belief that money is as ‘good as gold’. Even though the world changed dramatically in 1973, the perception of money remained the same, and at the microscopic level nothing appeared to change. Both gold and ‘let it be’ money only have the value we believe them to have, but whereas we cannot create unlimited amounts of gold we could create unlimited amounts of fiat money. To prevent this happening all money is created in the form of  debt, such that the amount of money is linked to future activity. However, a debt-based system of money is also not without problems but that’s another story.

    Charles
    thanks. I look forward to seeing more of the book or even the whole thing!

    “At various points in history, the Sovereign took a particular interest in money … ” — this is a great story and I keep telling it to everybody as a riddle: How does the King make people accept his money? Sometimes, I add, no, not like in the French revolution where they guillotined trades people who refused to accept the currency. So far nobody was able to solve it, which only shows how wrong our common sense understanding of money is. Anyway, my question is, did it really happen in history? Do you have some references?

      I recommend David Graeber’s Debt: the first 5000 years as an excellent starting point.
