Well assuming a 'loan-first' theory of money creation, a loan could only be made once a timed deposit equal to it had been agreed elsewhere. The loan would have to be arranged along with the deposit and a mechanism for getting that deposit back to the bank that made the loan via interbank lending. You're still creating money by creating the debt/deposit. That's what money is - the representation of a debt. And each taking out of a new loan will create new money, while any repaid loan destroys it, which is what we already have now. Except in this instance, the deposit would be out of circulation for the duration of the loan, so it isn't really creating new money. It's more like you giving me a tenner for a week, then me giving it back to you at the end of the week.
Assuming the money for the initial deposit already exists somehow, it still needs to match the loan in time, so the deposit is out of commission for the length of the loan, but the loan can create a new deposit. Thing is, lots of people are not going to want to tie up their money, so a great deal of the money won't be available for new loans. Assuming a strict enforcement of 'deposit-first' rules, only a very small amount of funds will be available for loans, and any funds used for loans will be taken out of circulation for the duration of the loan. So in theory, there would have to always be the same amount of money in circulation. Economic growth would lead to deflation, so there would need to be some kind of mechanism to prevent that - a periodic expansion of the money supply.
