Err, I still have questions. I understand how banks increase the money supply. But leaving aside for the moment injections of new money by the Fed, isn’t Kevbo right - that debts + interest > all the money in the economy?

I think Freddy the pig sorta answered this in post #37

I also have a question about the process by which the Fed exchanges bankers’ book-keeping entries for cash. It appears the Fed only exchanges bank reserves for cash, not other entries (for example - the ones that represent customer deposits). Is that about right? If so, that would explain how bank runs could still occur.

Sorry, I don’t quite remember enough from college to answer this question, but that sounds right
[QUOTE=LinusK]
I also don’t exactly have an answer to the question of whether it’s the loan or the deposit the represents the ‘new’ money in process by which banks create new money. But perhaps the question doesn’t have an answer, or the answer doesn’t matter.

Well, first of all, what do you mean when you say money? Do you mean actual bills and coins? or do you mean value/wealth?
Value/wealth is added to the economy any time someone produces a good or a service. To take the previous example:
You deposit $100 in the bank. The bank lends me $90, and keeps $10 on reserve. At this point, there is$190 in our economy. Your deposit that you can get to at any time, and the $90 that the bank just loaned me. Now, I didn’t borrow money just for fun. I intend to do something with it. I buy $90 worth of wood and nails, and I build a birdhouse. I then sell the birdhouse for $100. I pay off my bank loan - $91 (original $90 + $1 of interest).I now have $9 more than when I started. The bank received back 91. They pay the interest on your account .50. You now have 100.50 in the bank. The bank has a profit of .50, and I have $8. A total of $109 from an original $100 deposit. The value was created when I took $90 input (would and nails) and created $100 worth of output (the birdhouse). Now the bank is free to loan out $90.45 ($100.50 - %10 that needs to be on reserve).
Another thing to note is that there is a difference between assets and cash flow. In the example above, the bank has assets of $100 ($10 cash and $90 IOU from me). However, they could run into a cash flow problem if you came and wanted to withdraw $15. This is kinda what a bank run is. More people want to pull their money out then the bank has cash on hand.
Hope this helps. Feel free to ask more if I didn’t explain well enough.
