Yes, of course that can happen in theory but in practice it doesn't and banking is based on the fact that it doesn't. Because only a proportion (fraction) of what is in "demand deposits" will be withdrawn at any time, the banks are free to lend the rest.
Yes, I am saying that what happens today is a sort of "full-reserve banking" only not as rigid as what you mean by it: banks lend from the part of "demand deposits" they know from experience are not likely to be withdrawn as well as from "time deposits". In other words, from your point of view, your banking reform is not really needed.
I don't know what you mean by this : that a bank can lend 30 times the amount of money deposited with it?
On this last point, for one. I don't think any of the Nobel Prize winner you cite nor Mervyn King believe that when somebody deposits £100 in a bank that bank can then lend up to 30 times that amount, ie £3000. I don't think either that they think that a bank creates the money it lends by a mere keyboard stroke. Nor are they in favour of all money being so-called "debt-free money". What they are concerned about is trying to assert central bank control over the amount of bank loans.
I know that's why you don't like it, but it's probably accepted by your Nobel Prize winners. I think it's contrived too, but at least it accepts that a bank can't make a loan unless it has a corresponding deposit.
And you think banks can do the equivalent of this?
i) This is flat out wrong. This is precisely the thing that you have not grasped.
The banks cannot be said to be lending the money they receive as deposits. They are creating new money which doesn't sit around - it circulates.
If what you said was true, then only the monetary base could be said to be circulating - but clearly we have far more than that going around. The reason has little to do with the fact that depositors like to save their money. It is the fact that
unless they withdraw hard cash, then their money is always going to be somewhere in the banking system, existing simply as a liability entry in a bank's books, and as one bank loses these funds another gains. So when we consider the high street banks as a whole, they can create a great deal of money as loans just with keystrokes. When one customer circulates his money by transferring it to someone else's account at the same bank, it doesn't affect the bank at all. And when customers transfer money to other banks, it is going to be balanced by the transfers coming the other way ('clearing').
I suggest that you forget about the 'money multiplier' model, and just suppose instead that there is a central bank, and one big high street bank which has everyone's accounts (LLoydsNatwestHSBCBarclays). Now it should be straightforward to see that this big high street bank simply creates money when it issues a loan, out of nothing, and it can loan as much as it likes at interest, the only restriction being that it needs to maintain confidence that it can come up with cash (or other central bank money) for the tiny percentage that will require it at any time. Crucially, the bank is not affected at all by transfers between customers. Now it works the same way when you split up the big bank - interbank lending allows the four banks to operate as one.
There is a massive difference between fractional-reserve and full reserve banking and what we have is a million miles from full-reserve.
If you want to quote where my Nobel prize winners disagree with me, please go ahead, I will genuinely be interested.
It hardly restricts money creation that banks must have a corresponding deposit to every loan, because for every loan a corresponding deposit is created.
Last bit - yes, the banks are creating wristwatches whenever they lend a wristwatch.
