Banks only have a small portion of the money people deposit with them available for customer withdrawals. Most of it (90% or more) is loaned back out to borrowers. As a matter of fact, the amount they loan out is typically multiples of the amount they have on deposit.
So, you pull $10K out of the bank, the reserve requirements would force them to get a multiple of that from the accounts they loaned out....... but those people don't have any money.
Very quickly a run like this can collapse a bank without government intervention.
When you mention money Dutch, it's not even cash.
I'm not even sure at this point if all our money is even backed
by paper. So much is electronic.
Paychecks are direct deposited.
Businesses are paid by bank or credit card. That goes to the bank
account. But as 0s and 1s.
Loans are made from deposits, and money borrowed from the Fed.
Loan payments made electronically.
Absolutely none of this money, is actually money in the bank.
Banks have very little cash on hand, they dont need it now.
About the only cash that comes in, is from daily cash deposits from
Businesses, and from the armored car that delivers cash.
They don't even turn around a lot of the cash.
Remember the change shortage?
Many banks ship incoming coins out to a counter/sorter. Ie. That truck.
The get change in, in plastic rolls in boxes.
If people with a few thou$and started wanting their cash, the banks would
be out in hours. News of that a one bank would spawn people to rush
to their bank.
Everyone remember the toilet paper shortage?
Now imagine it folks can't get their money.
Happened in the Depression, was ugly.
Backthen money was money.
There wasn't electronic dollars that never physically existed.
