Where Does Money Come From?
Most people think that the government creates all of our money by printing banknotes, and minting coins. But that is not the case. Let's start by looking at where the government gets its income from.
Government Income
Banknotes are printed by the Bank of England (BoE) on behalf of the government. The BoE then sell those notes at face value to commercial banks, who use them to fill their cash machines and to hand over to us when we withdraw money from our bank accounts. The profits from the sale of these notes by the BoE (known technically as seigniorage) is passed straight back to the government, and netted the Treasury the sum of £2.3 billion in the tax year 2007/081.
The second source of government income is well known and hated by us all—taxes.
Finally, the government gains income through borrowing. If insufficient funds have been brought in through seigniorage and taxation to meet the government's spending commitments, it sells bonds. Bonds are the equivalent of a government IOU, and promise the holder that the government will buy them back at a future date for the value of the bond plus some predetermined interest.
Raising money through selling bonds has a huge downside, though. It means that the government incurs debt. And, like the rest of us with debts (on a credit card, for example), the government ends up paying a sum of money each year simply to service those debts. Government estimates for 2007/08 put the figure that it will have spent on servicing its own debts last year at a staggering £30 billion2—over 20% of the total amount of income tax that we all paid!3
Money From Thin Air
Currently, around 97% of the 'money' in our economy isn't in the form of notes that you can fold, or change that weighs down your pockets—it's in the form of credit (or debt, depending upon which side of the transaction you are standing). So the real question to be asking if we want to understand where our money comes from is how all of this debt appears?
Our commercial banks create money as debt, effectively from 'thin air'.
Imagine a person paying, to keep the example straightforward, £100 in notes or coins into their bank account. Now, bankers know that most of the time, most people leave their money in their bank accounts; we tend to pay for goods with our debit cards, or by writing cheques to one another. Consequently, if a bank has just received £100 in cash it knows that there is little chance that the depositor is going to come along and ask for it back at any moment.
Knowing this, banks only keep on hand a certain proportion of deposited funds; the amount that they reasonably expect they will need to cover any requests for withdrawals. The amount is termed the reserve ratio, and for any funds deposited, a bank will solely keep the amount of the reserve ratio on hand, and lend out the remainder. The whole process is known as fractional reserve banking (FRB).
So, to carry on our example, if the bank that person paid his £100 into maintained a reserve ratio of 10%, the bank would accept the £100 deposit, keep £10 on hand, and lend out the remaining £90.
But what happens to that £90 loan? The individual or business who takes it from the bank will probably not just spend it straight away, but deposit it into their bank account. If they do so in cash, the whole process can start again. Assuming that their bank also maintains a 10% reserve ratio, the bank will accept the £90 deposit, keep £9 on hand, and lend out the remaining £81.
And so the process continues. In fact, if fully worked through the system, that original £100 deposit will end up having 'created' a total of £1,000 that can be spent in the real economy.
In accounting terms, no money is actually created. If each borrower were to pay back their loan in sequence, the debts would unwind until we were left with our original £100 deposit at the first bank. This is why those who defend the existing system will tell you that no new money is really created.
What these folks conveniently overlook, however, is that in real terms, as opposed to accounting niceties, new money has appeared—it's in your hands, and you can spend it. And as long as new bank deposits are being made, the process above can continue.
Keeping The Merry-go-round Turning
And what allows the entire process to continue is our central bank—the Bank of England. Remember the bonds that the government sells to raise additional funds, the Treasury IOUs? Well the BoE will, from time to time, buy bonds in the market. To pay for its purchases, the BoE genuinely does create money from thin air, and credits the seller's account with money that it has just decreed should exist.
This process injects new money into the economy, which spreads about and ensures that the fractional reserve system described above never grinds to a halt.
If it wishes to, the BoE can use the same process in reverse; selling Treasury securities and destroying the money the purchaser pays. In this manner, the BoE has a crude control mechanism available for determining how much money exists in our economy at any one time.
The BoE also sells money to the commercial banks. These banks buy money at one rate, then loan it out to their customers at a higher rate, pocketing the difference.
The above is, of necessity, a simplified explanation of how FRB operates, and the role played by the central bank. The Bank of England do not appear to have ever produced a layman's guide to these processes, but the US Federal Reserve has. Although several years old now, this document is still a good guide to the operation of a fractional reserve system, and largely applicable to the regime in the UK as well as the US. If you wish to look at the technical detail for the UK system, the Bank of England's Handbooks In Central Banking series of publications, and in particular Handbook #24 (Monetary Operations), is a good place to start.
And whilst the above is a simplistic version of the processes at work, remember that much of the complex language and obscure practice of the banking industry is designed to mask its operations from public scrutiny. At its heart, it is a simple fraud: central banks genuinely creating money from thin air, and commercial banks lending money that's not rightfully theirs to loan. As the famous economist JK Galbraith once noted: "The process by which banks create money is so simple that the mind is repelled."
