The Invention of Money

By John Lanchester

When the system buckles, how do we know what money is really worth? In three centuries, the heresies of two bankers became the basis of our modern economy. When the Venetian merchant Marco Polo got to China, in the latter part of the thirteenth century, he saw many wonders—gunpowder and coal and eyeglasses and porcelain.

One of the things that astonished him most, however, was a new invention, implemented by Kublai Khan, a grandson of the great conqueror Genghis. It was paper money, introduced by Kublai in 1260. Polo could hardly believe his eyes when he saw what the Khan was doing:

He makes his money after this fashion. He makes them take of the bark of a certain tree, in fact of the mulberry tree, the leaves of which are the food of the silkworms, these trees being so numerous that whole districts are full of them.

What they take is a certain fine white bast or skin which lies between the wood of the tree and the thick outer bark, and this they make into something resembling sheets of paper, but black. When these sheets have been prepared they are cut up into pieces of different sizes.

All these pieces of paper are issued with as much solemnity and authority as if they were of pure gold or silver; and on every piece a variety of officials, whose duty it is, have to write their names, and to put their seals.

And when all is prepared duly, the chief officer deputed by the Khan smears the seal entrusted to him with vermilion, and impresses it on the paper, so that the form of the seal remains imprinted upon it in red; the money is then authentic. Anyone forging it would be punished with death.

That last point was deeply relevant. The problem with many new forms of money is that people are reluctant to adopt them. Genghis Khan’s grandson didn’t have that difficulty.

He took measures to insure the authenticity of his currency, and if you didn’t use it—if you wouldn’t accept it in payment, or preferred to use gold or silver or copper or iron bars or pearls or salt or coins or any of the older forms of payment prevalent in China—he would have you killed. This solved the question of uptake.

Marco Polo was right to be amazed. The instruments of trade and finance are inventions, in the same way that creations of art and discoveries of science are inventions—products of the human imagination. Paper money, backed by the authority of the state, was an astonishing innovation, one that reshaped the world.

That’s hard to remember: we grow used to the ways we pay our bills and are paid for our work, to the dance of numbers in our bank balances and credit-card statements. It’s only at moments when the system buckles that we start to wonder why these things are worth what they seem to be worth.

The credit crunch in 2008 triggered a panic when people throughout the financial system wondered whether the numbers on balance sheets meant what they were supposed to mean.

As a direct response to the crisis, in October, 2008, Satoshi Nakamoto, whoever he or she or they might be, published the white paper that outlined the idea of Bitcoin, a new form of money based on nothing but the power of cryptography.

The quest for new forms of money hasn’t gone away. In June of this year, Facebook unveiled Libra, global currency that draws on the architecture of Bitcoin. The idea is that the value of the new money is derived not from the imprimatur of any state but from a combination of mathematics, global connectedness, and the trust that resides in the world’s biggest social network. That’s the plan, anyway.
