This is my basic view of FRB put forth in another thread
I don't think the bank is trading insolvent. I think it is more like insurance companies. There is no way they can pay out all their policies at once, but it is risk management. The same basically is true for banks.
But I'm curious to hear opposing views.
Well, yeah, the whole thing about person borrowing 90 then next person borrowing 81 etc, obviously isn't real world. When was the last time you went to the bank for a loan and were told you had to borrow exactly 90% of what the last person borrowed?
So in real world, let's say a (simplified) bank balance sheet looks like
Assets
Cash - 10,000
Loans - 50, 000
Liabilities - 60, 000
The bank is now levered 1:5. It has 20% reserve. If someone then came in and say wanted a 30,000 loan, that 30,000 would be added to both sides of the balance sheet like so
Assets
Cash - 10,000
Loans - 80, 000
Liabilities - 90, 000
30,000 loan added to the asset side. And then 30,000 would added to the person's account as a liability to the bank.
So the bank creates new credit (after all, credit is just a book-keeping entry), but it has to pay interest on the liability side whereas it is receiving interest from the loan. The difference between the 2 interest rates goes to the banks operating expenses, profits etc.
This was in the FRB world.
In the current world the reserves required consist of Tiered Assets rather than just cash which comprise things like Bonds, Gold, etc. You can look it up on wikipedia.
As far as I know, and Steve Keen did an analysis of this, banks create credit and it can go beyond the reserves as they shore up the reserves later on. Which kind of makes sense with all the transactions the bank does every day, they don't want to give up business just because they temporarily don't have the reserves.
Which is why it is not true to say that banks loan out reserves. They don't. And that's why expanding bank reserves doesn't automatically create lending and inflation, as we've seen in the past few years.
Banks lend if they have creditworthy borrowers.
The entire problem is not with FRB itself, which I believe would exist in a free market, but the abuse that occurs when the government gets involved and starts manipulating interest rates down, implicitly and explicitly backing the banks and of course ultimately bailing them out with taxpayer money. Basically when this happens banks can increase volume massively as perceived risks are lessened. That's why they have massive amounts of money now, because of increased volume, not some ridiculous interest rate spread. Of course, the risks still exist but remain percolating and building under the surface. There's no such thing as a free lunch. Someone always has to pay.
