Most new money begins as a bank loan
When a commercial bank approves a loan, it usually does not hand over cash someone else deposited. It records a loan as an asset and credits the borrower’s account with a matching deposit. That deposit is spendable money: the borrower can use it to pay a contractor, buy a car, or cover rent. When the recipient deposits the payment at another bank, the money remains in the banking system, just in a different account.
This is why bank lending can expand the supply of money without a printing press. The process is often called money creation through lending: a loan creates a deposit, while the borrower takes on an equal debt.
The limits—and the reverse process
Banks cannot create unlimited money. They need borrowers likely to repay, enough capital to absorb losses, and access to funds to settle payments with other banks. Interest rates, regulation, risk, and demand for loans all affect how much lending occurs.
When a borrower repays the principal, the bank removes that amount from the loan balance and from the deposit money in the system. In that sense, repayment reverses the original creation. Interest is different: it is income to the bank, not money that disappears in the same way.
What “printing” leaves out
Central banks create physical cash and electronic reserves that banks use to settle with one another. But adding reserves does not automatically put the same amount into household checking accounts. Government spending can also add deposits to the private sector, while taxes and borrowing affect where money sits and who holds it. For everyday spendable money, bank lending is a central creation mechanism—not simply a matter of the government turning on a printing press.
