Ever wondered how much money is there in the world per person if we could somehow split it equally? I came across this thought experiment recently and it's actually pretty wild.

So here's the premise: imagine we took every single dollar, euro, and yuan in circulation globally and divided it evenly among all 8.16 billion people on Earth. Sounds utopian, right? Well, the math gets interesting.

The key here is understanding M2 money supply, which basically covers all the cash floating around in economies worldwide—your checking account, savings deposits, money market accounts, anything you could access relatively quickly. It's different from total global wealth because it doesn't include real estate, stocks, or other assets that aren't liquid cash.

According to CEIC data from 2024, the global M2 money supply sits at about 123.3 trillion dollars. When you divide that by the world's population of roughly 8.16 billion people, each person would theoretically get around 15,108 dollars. That's approximately 13,944 euros depending on exchange rates.

To put that in perspective, that's enough for a two-year grocery budget for an average household, a decent used car, or—and this is the kicker—a brand new Dacia Sandero without any upgrades. Not exactly life-changing money, but definitely not pocket change either.

What's interesting is how this varies by country. I looked at Spain's numbers out of curiosity. With an M2 supply of about 1.648 trillion dollars and a population of roughly 49 million people, each Spaniard would receive around 33,571 dollars, or about 30,968 euros. That's more than double the global average, which tells you something about wealth concentration in developed economies.

The real takeaway here isn't that we should actually redistribute the world's money—obviously that's not happening—but rather how this simple calculation reveals the massive gap between how much money is there in the world per person versus actual global wealth inequality. Global private wealth in 2024 was estimated at nearly 488 trillion dollars by UBS, which is almost four times the M2 money supply. That gap? That's where assets, property, and investments live.

It's a useful mental framework for understanding monetary systems and why cash alone doesn't tell the whole story about economic inequality.
