How much money is in the world?
The Real Answer
There is no single official number for how much money exists in the world because 'money' is defined differently across countries and monetary systems. Physical cash is only one part of it; broader measures can include different kinds of bank deposits and other liquid instruments, and the contents of measures such as M2 or M3 are not identical everywhere. Stocks, bonds, real estate, and crypto are assets or wealth, not simply additional piles of money that can be added to one universal money-supply total.
You ask how much money exists because you want one enormous number, then start counting bank deposits, houses, stocks, and crypto as if they were the same pile. You wanted one total and ended up arguing about what the word 'money' means.

The question sounds as if there should be one giant total somewhere. It gets slippery as soon as you ask whether a bank deposit, a stock, a house, or cryptocurrency counts as money or as an asset priced in money.
