When someone puts $10 in a bank, it most certainly gives the bank something they can do something with. In this case they can lend $9 out - assuming 10% reserve. On the balance sheet the bank then has $10 on the liability side - the deposit - and $9 loan and $1 reserve on the asset side. I think that you're confusing accounting with business.
- stephen_g 8y agoThat’s called the ‘money multiplier model’, it’s an incorrect model that doesn’t actually describe how any modern bank works. It’s basically a myth at this point. I’m not confusing anything. Believe it or not, banks actually have to follow double entry accounting rules, and follow regulations about capital adequacy. Most countries don’t even have a reserve requirement, deposits generally don’t factor into lending at all.

- derriz 8y agoWhat exactly isn't true in my statement? - banks take in cash in from depositors (and other creditors) - banks lend out cash to borrowers - banks do not lend out all the cash that they've borrowed - they keep some in reserve Do you have the name of any retail bank which does not operate according to this model? What does their balance sheet look like? The "textbooks" reference is not relevant here - my experience is from working in retail banking operations.
- neilwilson 8y agoThere is a academic paper here explaining how it works. https://www.sciencedirect.com/science/article/pii/S1057521914001070 https://www.sciencedirect.com/science/article/pii/S105752191... Essentially the bank can make the loan with a zero balance sheet. If you work at the back end of a retail bank operation then you'll know that the loan department and the treasury department do not talk to each other about quantities. They talk to each other about price. Other than that the two operations operate in parallel. 'Funding' is just swapping the liabilities around in the market to try and reduce the amount the bank pays out in interest.

What is described is a special case where a highly leveraged bank could find itself temporarily insolvent, with a very limited window of exposure before the bank would be found guilty of criminal fraud.” https://www.cooperative-individualism.org/dodson-edward_review-of-richard-werner-can-banks-individually-create-money-out-of-nothing-2015.htm https://www.cooperative-individualism.org/dodson-edward_revi...
- soVeryTired 8y agoI think the problem with what you're saying is the ambiguous use of the word 'cash'. Deposits, reserves, and physical currency are all 'cash' in some sense, but here it helps to be precise. Banks don't 'lend out cash', they create deposits. Deposits are liabilities for banks. When a bank takes on a deposit, it also takes on a corresponding asset: either a loan in its books, or an increase in its reserve account. In practice the reserve ratio is unimportant for a bank: in Canada and the UK the ratio is 0%. The real constraint on a banks ability to create money is it's leverage ratio, i.e. (assets - liabilities)/assets. In reality the formula is more complicated and uses risk weighting by asset class, but that's the crux of it.
