i’m just going through some basic financial philosophy discussions and i’m just trying to clarify the basics.

how much money is there in total, in the world?

up until yesterday i had assumed that the total amount of money in the world is zero ($0) because what one person has in bank account, another person has in debt at the same time, since money is literally nothing else than a codified form of debt.

now i’m wondering, is this even accurate? if a big bank takes out a loan from the central bank, say, it takes $1B in loan, then it has $1B in money on the account but also $1B in liability at the same time, so the sum is zero. However, there is an interest on the loan, let’s say 2%. Then the bank owes $1.02B actually, while only having $1B on the account. So the total amount isn’t zero, it’s negative. Is this correct?
