The goldsmiths tale
Money As Debt explains how the financial system came to be. And it is an interesting story. Once upon a time when gold was internationally accepted as money, goldsmiths fabricated gold coins of standardised weight and purity. They were a trusted source of these gold coins. The goldsmiths owned a safe where they stored their gold. Other people wanted to store their gold there too because those safes were well guarded.
The goldsmiths started to make a business out of renting safe storage. People storing their gold with the goldsmith received a voucher certifying the amount of gold they brought in. At first these vouchers could only be collected by the original depositor.
Later this restriction was lifted so that any holder of the voucher could collect the deposit. From then on people started to use these vouchers as money because paper money was more convenient than gold coin. Depositors rarely demanded their gold and it remained with the goldsmiths.
The goldsmiths also had another business, which was lending out their gold at interest. Because depositors rarely came in to collect their gold, the goldsmiths found out that they could also lend out the gold of the depositors at interest. When the depositors found out about this, they demanded interest on their deposits too. At this point modern banking started to take off, and paper money became known as bank notes.
Borrowers also preferred paper money to gold coin, so the goldsmiths, who had now become bankers, found out that they could lend out more money than there was gold in their vaults. Bankers started to create money out of thin air. This is fractional reserve banking because not all deposits were backed by gold reserves. The new money was spent on new businesses and that hired new people so the economy boomed.
When depositors found out that there were more bank notes circulating than there was gold in the vaults of the goldsmith’s bank, the scheme could run into trouble, but mostly it didn’t. Depositors received interest and this enticed them to keep their deposits in the bank. People trusted their bank as long as they believed that debtors had no trouble repaying their loans.
Sometimes people started to have doubts about their bank, and worried depositors came to the bank to exchange their bank notes for gold. This is a bank run. When that happened, the bank could run out of gold and close down because not all the gold was there. The bank’s bank notes could become worthless, even when borrowers had no problems repaying their debts. When the bank notes became worthless, the money that the bank had created out of thin air suddenly vanished. This was a financial crisis.
A lot of money had suddenly disappeared so people had less money to spend. This could hurt sales so that some businesses could go bankrupt. Those businesses could not repay their debts at other banks and depositors at those banks might fear that their bank would go bankrupt too. This could cause more bank runs and more money disappearing, so that things would become even worse. This is an economic crisis. This is the way a financial crisis could trigger an economic crisis.
Regulations and central banks
Measures have been taken to forestall financial crises and to deal with them if they occur. Banks needed to have a minimum amount of gold available in order to pay depositors. Central banks were instituted to support banks by supplying additional gold if too many depositors came in to collect their gold. Central banks could still run out of gold but this was solved when the gold backing of currencies was ended. Nowadays a central bank can print new dollars or euros to cope with a shortfall.
Regulations limit the amount of loans banks make and therefore the amount of money that exists. But everyone can lend to anyone. Alternative forms of financing circumvent the regulations imposed on banks. For example, corporations can issue bonds or use crowd funding. Human imagination is the only limit on the amount of debt that can exist. As long as people expect those debts will be repaid, even if it is with new debts, there is trust in these debts. The financial crisis of 2008 demonstrated that trust in debts can suddenly disappear.
