Sorry to drag this up again, but I still need help understanding this issue. Thanks to everyone who has contributed to the thread.
Quote from scriabinop23:
3) fractional reserve banking multiplier. This is the key to the above argument. If the reserve ratio is 10%, then $1B of money created by the fed turns into a total $9B money created by the banking system (ponzi scheme).
....
So when in #3 the banks are forced to writedown bad loans (which are assets on their books) by 50%, they still are obligated to maintain their reserve ratios. They must raise more money so the assets balance out their liabilities (deposits). ie, bank has 90B in assets that are written down to 40B, and a reserve of 10B. Total bank deposits are 100B. So they have 50B of worth against deposits of 100B. They are entirely insolvent if people want their money. As a result, they stop lending until they recapitalize (and because new regulations come in) sufficiently. This results in the multiplier number going down, thus less money created.
Remember multiplier number is inverse to the reserve ratio. 10% reserve ratio = 10 multiplier. 25% reserve ratio = 4 multiplier.

I started this thread by stating that I understood how money is created by the banks, but maybe I don't. In the explanation above, it appears that banks can only lend money they have on deposit. Even though a deposit is in a sense a liability, it's still money that came onto the balance sheet from outside, it wasn't created. It's no different from money given to a venture capital fund, for example, to be invested, except that a deposit might be called back at any time. It isn't money "created out of thin air", which is what I assume is happening. But maybe that's my problem?
Here is a thought experiment to illustrate. Suppose a bank has $1M in assets. If they are really restricted to the 10% fractional reserve, then they can loan $900K. If, as stated in the quote above, those loans get written down to half that, the bank is screwed, because they owe the depositors money that is now gone.
But I thought I understood that banks could push it even further, but considering the loan to be an asset, and lending against its presumed repayment. In this scenario, the bank with $1M in actual cash in the beginning could lend $10M. But then (and here is the thought experiment), if they foreclose on all $10M worth of loans and liquidate for 20% of the loan amount, they have the $1M with which to repay depositors and they have $1M in profit.
Obviously something is wrong here, because when loans are written down that severely, the banks become insolvent. So is it simply my exaggeration of the multiplier effect that is wrong, and banks really are restricted to lending an amount that is less than their actual deposits? Or do I have that right, but am missing another piece?
Thanks again.
