But those dollars themselves are not loaned out, nor are they even necessary. As I pointed out earlier, Canada doesn't even have a reserve requirement. Banks can make loans with no deposits whatsoever.
It doesn't matter whether those literal dollars are loaned out or whether they're reserved so that other dollars can be loaned. It's the same thing.
It really isn't the same thing. The dollars that go to the borrower are created, on the spot, when the loan is made. It is not a pile of saved, accumulated dollars that are loaned out.
It isn't Bill Gates' $30,000 deposit, or any part of it, that is being loaned out. New money is created at the time of the loan. Before the loan the world has X dollars, and after the loan the world has X + Y dollars.
And that is a crucial distinction, because it means that capital can be created on the spot, and the cost of capital is based on the interest rate charged by the Fed, and not on supply and demand (because there is not a limited amount of capital).
This seems to be getting off track. When Bill Gates deposits $30,000 in a bank, what happens to those dollars? Is it your contention that the bank holds 100% of its deposits as reserves, or do they mostly get loaned?
They absolutely do not get loaned. Everything, initially, goes into reserves. If he deposits cash (unlikely), it goes into the drawers or the vault, which count as reserves. If he deposits a check from Bank B into Bank A, Bank B will transfer that amount from their reserve acct. at the Fed to Bank A's reserve acct. at the Fed. If he deposits a check from somebody else's acct. at Bank A into his acct. at Bank A, no reserves get moved at all, and Bank A just makes the adjustment on its ledger.
The same thing happens whenever Bank A receives any kind of payment - it is either cash, or the net change is realized through their reserve account. A reserve account is just a bank's own bank account. When they pay an employee, which is probably written from an account in Bank A, their reserve account goes down by that amount. When you cash a check, they mark down your account, then hand you vault cash, and their reserves have gone down by that amount. Reserves aren't lost money or anything.
But when they make a loan for $30,000, they do it by expanding their balance sheet on paper. If the loan is to one of their own account holders, they just mark his account up and start billing him, and they shouldn't have to change their reserve position at all. If the loan is deposited at another bank, they transfer reserves to that bank's reserve account. But either way,
the total amount of reserves does not go down by $30,000. (If anything, $3,000 has to be added to reserves.) The loan is brand new money, created by the bank expanding its balance sheet. But it works just the same as any other dollars.
It's really not that different that the old money multiplier story, in that banks created money in that scenario as well. Your $100 cash deposit somehow became $1000, right? Well, that's because banks loaned out money they didn't physically hold by creating it. They expanded their balance sheet, and their marks on a ledger worked just like real money - they paid bills with checks, etc. You could count how much money there was, you just couldn't cash it all in, because the physical dollars did not exist. But in the old story, your deposits were the determining factor in how much money existed - you deposit $100 in cash, and the world suddenly had $1000 - which was not true.

We went down this road because people were insisting that everything they saved contributed to investment, their stock purchases contributed to investment, their savings were necessary for investment, the amount they saved affected investment, etc., and this just isn't true. Money takes a different path than we were taught.
