Money is created when a bank creates a loan, by starting with nothing and then splitting that nothing into a credit in one account (the borrower’s checking account, usually) and a debit in another (the borrower’s loan balance). From there, most transactions are digital where an ACH transfer or similar results in some numbers being subtracted from one account and added to another.
Almost all of this happens on computers, and even before computers it just happened literally on a paper ledger, with paper checks.
You might ask, “wait where does the bank get its money from to be able to allow money to be withdrawn or transferred to another bank?” If the bank doesn’t have the liquidity to do so, it can always borrow money from other banks or the government, with the last resort in the United States being the federal reserve banks, who by the way also print all the paper currency. So having that backstop is important for regular banks to have the power to create money, but the actual creation of money happens digitally to begin with, regardless of whether the bank later needs to distribute paper bills or borrow from the federal reserve.
Not exactly. The central banks acting as a lender of last resort encourage the commercial banks to create money in this way, but be assured that the actual creation occurs whether the bank needs to borrow money or not. The definition of money supply looks to the balances in checking accounts, and creating and disbursing a loan increases the balance in a checking account (while simultaneously increasing the negative balance in a loan account, but loan balances don’t shrink the money supply), and as that money is spent it increases balances in someone else’s checking account.
It’s how all of it works. Money is just balances on double-entry bookkeeping, and the paper currency essentially is a piece of paper that the bearer of that paper is good for moving the balances in that ledger system.
By that logic any bank could grow arbitrarily large by just underwriting more loans. Then there’d be no competition between any of them and my job would be so much easier.
Yes, the limit to commercial bank lending is creditworthiness and default risk (because the bank is left holding the bag when a borrower doesn’t repay), and the cost of maintaining liquidity (the bank can borrow against the loans it owns, but it may cost a higher interest rate than they’d earn on the cash they’ve lent out). This paper lays it out pretty clearly, and is basically the near unanimous view among macroeconomists.
Or, in some regulatory environments, banks are required to maintain a minimum fractional reserve, which limits the total amount of loans it can lend out with its underlying assets.
But the money is created when the loans are created, and destroyed when the loans are repaid. The other stuff behind the scenes to give the system stability is important, but doesn’t actually create or destroy money.
We already have mostly digital currency.

Well only central banks can create it out of thin air. Normal banks lend other people’s money (fractional reserve banking)

And almost all of those ledgers are now digital.
