Right, nowhere close. Usually, bank reserves around $40 billion.
The TAF auctions were set up for a few reasons, one of which was to help banks remain solvent, not just overnight as the Discount Rate does, but for longer periods of time. As a result, from $40 billion in reserves the banking system went to (negative) $15 billion since December. Every penny that is in a bank, reserved for withdraw, is borrowed from the Fed at this point.
This is completely unprecedented. From what anyone can tell, the Fed is accepting mortgage debt, and other iffy collateral, in exchange for monetary injections. They are taking assets, which are really worth anywhere from 0% to 70% of their book value at full value and inserting money into the system to keep the entire system solvent.
This graph illustrates the issue. And it doesn't tell the whole story since the number extends nearly to the bottom as the current non-borrowed reserves level is about (negative) $15 billion. Or you can look at it from the other side and say borrowed reserves are at $15 billion.
If the Fed hadn't been on top of things and intervened starting in December, as far as I can tell, the banking system went insolvent in January.
