Ever thought about what happens if we just split all the world's cash equally among everyone? Like, literally every dollar, euro, and yen pooled together and divided by the global population. Wild thought experiment, but the math is actually interesting.

So here's the thing - when people talk about money in the world, they're usually thinking about M2 money supply. That's basically all the cash circulating plus bank deposits you can access pretty quickly (up to 2 years). It's the money that's actually spendable, not tied up in real estate or assets that take forever to convert to cash.

According to CEIC data from 2024, global M2 money supply sits at around 123.3 trillion dollars. Sounds insane, right? But then you divide that by 8.16 billion people on the planet, and suddenly it gets more realistic. Each person would get approximately 15,108 dollars. Or about 13,944 euros if you're keeping track.

Here's where it gets funny - that amount is basically enough to buy a Dacia Sandero. A second-hand car. Or if you're more practical, it covers two years of groceries for an average household. So yeah, that's how much money is there in the world per person when you do the equal distribution math.

The contrast is wild when you realize that global private wealth is actually 487.9 trillion dollars according to UBS's 2024 report. But that includes real estate, businesses, investments - all the stuff that's not liquid cash. The per capita cash figure is way more modest.

Now here's the kicker - if you run the same calculation just for Spain, the numbers look better. Spain had about 1.648 trillion in M2 money supply in late 2024, with roughly 49 million inhabitants. Each Spaniard would theoretically get 33,571 dollars, or around 30,968 euros. Nearly double the global average. Which tells you something about how differently wealth concentrates across regions.

It's a sobering way to think about global inequality - and a reminder of how much of the world's actual liquid cash is concentrated in a few developed economies. Makes you wonder what the numbers look like if you exclude the top 10 countries, right?
