Many years ago I had a thought. Quite a big one, actually. It was hardly original, but to my mind it raised a question that demanded an answer.
The thought was this: the amount of money denominated in any particular currency isn’t fixed – in almost all cases it increases over time. It must do, otherwise economies wouldn’t be able to grow (at least not in units of the aforementioned currency). The question, therefore, is where does the extra money come from?
Luckily, the place I was working at the time contained a number of people whose job was to know about the economy and economic policy. Some of them would go on to related careers in government, journalism and finance. Surely they could tell me where money comes from.
But here’s the thing, none of them could. It’s not that they were stupid. They knew the facts and could crunch the numbers required to get their degrees and do their jobs, but clearly that knowledge didn’t include an answer to my question.
Of course, even I knew where physical money, i.e. cash, comes from. The notes are printed and the coins minted by the state. However, in a modern economy, cash is the loose change of the money supply – most of which only exists electronically in the form of bank deposits and the like.
So where does that sort of money come from? None of the people I asked knew. It’s strange because while we talk endlessly about how money is earned, spent, taxed and redistributed, how it comes into being barely gets a mention.

SubscribeI’m amazed that nobody commented on this article. Anyway, you’re right that banks create most of our money, but actually it’s not really a big deal. Admittedly it took me many months of research to reach that conclusion, because the idea is so different from what we’re normally lead to believe.
Essentially all of our money is an IOU owed by a bank to the holder of the bank account or the cash. Banks aren’t really doing anything special by writing IOUs – anyone can do it. In fact, if you look at the banking regulations, you’ll see that it’s taking deposits which is the more regulated activity. Don’t worry – banks don’t get rich by writing IOUs to other people.
The idea of a bank is that instead of you trying to pay your local supermarket £50 with your personal IOU (which of course they won’t accept), you go to a bank, write them an IOU for £50, and they write an IOU to you for £50 in the form of new money. You then transfer that to the supermarket, who accept it because the bank has to keep its promise to them even if you default on your IOU to the bank. As long as the bank has enough net worth to cover all the defaults, all users of the money are fine.
Of course, some people do default, which means that the bank’s owners end up losing out. They need some sort of income to cover the defaults (as well as their costs of doing business and any profit), and that means they need to charge fees or interest on loans.
It’s explained in my Money and Banking video.
In general, to understand this and other topics in economics, look at how each decision or action affects each person’s net worth – what you own plus what you’re owed minus what you owe – and it all makes sense.
