They give your money to that guy. And he puts it in his account at the bank and they give it back to you. The money is still real though. Without the deposits they could not make any loans to begin with.
If someone comes to take out a loan for $1000 and withdraw the money what would happen? They'd go get the money everyone left there and give it to the new customer. Now they bank has no money because they just lent all the deposits. $1100 in deposits and $1100 in loans
“ Without the deposits they could not make any loans to begin with.”
Incorrect, banks create deposits when they issue loans and only require reserve balances sufficient to satisfy net flows of funds between institutions.
They can also borrow those reserves.
So deposits are required to increase profitability, and of course a minimum level of profitability is required to be solvent, but banks in now way “lend out deposits”.
If you actually believe this describes the process then follow me on this thought experiment.
TWB (unrelated to SVB) realizes that it’s in trouble - customers are taking a lot of their deposits out, and confidence in the institution is low.
So, instead of trying to liquidate some of their assets or raise capital (which is what would be conventional) they decide to lend their bank president a trillion dollars of interest free loan with a recall feature, on the contingency that he deposit it in a non-interest bearing account with a 300 year notice requirement.
In your understanding of the mechanics of banking; this is fine. The bank magics $1tn of deposits out of thin air, records an equivalent asset, and can then just pay all of their customers from these new deposits they have.
By issuing deposits, each bank creates essentially its own money which is valid as long as it is inside the bank (used in transactions with other clients that use the same bank), but when clients send money to other banks, the bank has to use 'central bank money'.
Which means banking system as a whole creates 'private money' when flows of 'central bank money' between banks are balanced, but each individual bank cannot do it faster than others, otherwise these flows will be negative and it will be losing 'central bank money' and/or hard assets (which would be sold to acquire 'central bank money').
