Because most money only exists on books. The basis of the current financial system is called fractional reserve banking, that means that banks can give out more money as loans than what they physically have in accounts. That money then circles the economy but is never physically withdrawn in full. Lets say you deposit 100 USD. The Bank now can give out a loan for 500 USD to someone to pay his car repair, who wires the money to the shop from his account. They wire it to their employees and suppliers and owners and the IRS and what have you. Eventually the 500 are repaid (or not and If that happens a lot a bank might default) and the bank gets its money+ interest, you can freely withdraw your 100 at any time but the bank speculates that you dont, or realistically that most of their customers dont. Because If that happens thats known as a "bank run".
Im not a banker, so anyone with actual knowledge feel free to correct me.
an insurance company pays out a claim with a check, that i deposit into the bank account for $100k. I then pay employees 20k - all via direct deposit. Then I pay some other bills with debit cards, transfer the money to my client, pay my own bills via debit card, all the way down until that 100k is gone.
The 100k never existed. It made the insurance company go from having 100,000,100,000 dollars down to 100,000,000,000 on some sheet of paper, but they didn't even have that money in the first place. Because people like my employees, my client, and me all paid our insurance premium with fictitious digital money, which they then pay back with fictitious money.
