The Great Conversation: What Makes Money Money?
Hello everyone, and welcome to The Great Conversation.
Most of us use money every day without thinking very much about what it actually is.
We work for it. We save it. We borrow it. We transfer numbers from one bank account to another and accept that something of value has changed hands.
But what exactly gives those numbers value?
In his article “The Hierarchy of Money,” Gregory Gundersen begins with a simple imaginary village using stones as money and gradually builds an entire financial system around them.
First come loans and interest. Then banks. Banknotes. Deposits. Settlement between banks. Central banks and reserves. Different currencies. International trade. A reserve currency. And eventually, fiat money.
Along the way, something fascinating happens.
The physical object we normally imagine as money becomes less and less important.
A bank deposit can function as money because other people accept it. Banks themselves use another form of money, central bank reserves, to settle obligations between one another. And between countries and financial systems, some currencies become more widely trusted and accepted than others.
Money, in this view, exists in a hierarchy.
And the higher we climb that hierarchy, the more we encounter something that cannot simply be printed, mined, stored in a vault, or entered on a balance sheet:
trust.
We trust that our bank balance can purchase groceries tomorrow.
Banks trust that central bank reserves can settle obligations between them.
Businesses and governments accept certain currencies because they trust the institutions, economies, laws, and financial systems standing behind them.
Gundersen’s thought experiment eventually reaches fiat money, where money no longer needs to be convertible into a physical commodity. It continues functioning because wages, debts, contracts, taxes, commerce, and financial institutions all operate through it.
That suggests something deeper about money.
Perhaps money is not simply a thing we possess.
Perhaps it is also a relationship between people and institutions, a shared agreement about what we will accept from one another as payment and what promises we believe will still be honored tomorrow.
And that makes money strangely human.
Because beneath the banks, currencies, interest rates, reserves, and balance sheets lies something societies have depended upon long before modern finance existed:
our willingness to trust one another’s promises.
Which raises a deeper question...
If the value of money ultimately depends on our collective willingness to trust the system behind it, what happens when that trust begins to disappear?
Take a moment to reflect.
