Ever wondered how much money exists in the world? I stumbled on this wild thought experiment recently and it completely reframed how I think about global wealth.

So imagine if you could take all the cash currently circulating in the world's economies and divide it equally among every single person on the planet. A farmer in Wisconsin, a potter in Delhi, a goat herder in Namibia, a dentist in Sydney—everyone gets the same slice. How much would that actually be?

Turns out there's a specific measure for this called M2 money supply. It's basically all the money in circulation plus bank deposits you could access relatively quickly—savings accounts, money market funds, stuff like that. Not your house or your car, just the liquid cash equivalent floating around in the global financial system.

According to CEIC data, the total M2 money supply worldwide in 2024 hit 123.3 trillion dollars. When you divide that by the world's 8.16 billion people, each person theoretically gets around 15,108 dollars. That's roughly 13,944 euros depending on exchange rates.

Here's the kicker—that amount is basically what you'd spend on two years of groceries for an average household, or a decent used car. Some people have pointed out you could literally buy a Dacia Sandero with that, which is kind of a funny way to put it into perspective.

It gets more interesting when you zoom in. Spain's M2 money supply in late 2024 was about 1.648 trillion dollars with roughly 49 million people. That means each Spaniard would get around 33,571 dollars or about 30,968 euros—almost double the global average.

The whole exercise highlights how much money exists in the world versus how it's actually distributed. Global private wealth is a different story entirely—UBS estimated that at 487.9 trillion dollars in 2024. So there's way more total assets out there, but when you're talking about actual liquid cash, the numbers get way smaller. Kind of puts things in perspective, doesn't it?
