When you say "proceeds" I'm not sure what you mean, unless you just mean the money created by borrowing (the loan).
Don't over think this. If I go to the bank and borrow $10,000, and that bank gives me a check, the $10,000 that is represented by the check is the "proceeds" from the check. Nothing more, nothing less.
Whether or not that money was "created by borrowing" is a matter of viewpoint I assume.
Lets say that I deposit that money into my checking account at another bank. What happens? When the check clears the fed, the fed marks down the issuing banks reserve/settlement account by $10,000. So the money really did come from some where. It came from the banks account at the fed. It wasn't created from thin air.
But then the federal reserve will credit the bank that I deposited the money into with the same $10,000. So now in theory at least, there is $10,000 more money in existence, at least until I repay the loan. So I suppose it may be fair to say that the deposit itself created "new money", but maybe not the loan.
The reason that I say the loan wasn't responsible is because we have already seen that the banks account at the fed was marked down by the same amount as the loan. Again, that money came from somewhere (the account that was marked down). Even if I deposited the money back into the same bank, the banks account would still be marked down, even though it would simultainiously be marked up by the same amount resulting in a net zero transaction.
Looking at it another way, what if I demanded a cash loan? Like physical currency? What would happen? Assuming the bank would even agree with that, the bank would take the cash out of it's vault, and exchange it for the note. Nothing changes with the banks account at the fed, the bank then has $20,000 less in reserves because vault cash counts as reserves, and if this transaction left the bank with less than the required reserves, the bank would then need to acquire overnight at least enough money to cover the required reserves. Again, the bank didn't literally print up this money, the loan resulted in the banks vault cash position being reduced.
I'd agree that a loan made to a customer becomes a deposit, a loan to a bank, which in turn is held as reserves reserves within the FRS, but here you claim that a bank loans customer deposits, it doesn't simply mark up accounts, but if a bank doesn't have the reserves until the end of the day when it acquires them from somewhere else, then they are adding digits to accounts.
OK, you got me. Assuming that the bank doesn't already have enough excess reserves, for the time period between when loan is consummated and the time that the bank acquires the money a few hours later, new money has been created. But then again I did state earlier that there may be some temporary money creation due to transactional time.
Given my claim that the bank does not loan customer funds, but simply creates them (the liability) and the loan (the asset) balances out the transaction. Then all that is needed is the reserves to meet the reserve requirement.
