Banks Hoarding Cash.

It’s reported that banks are hoarding cash.

Whose money are the banks hoarding?

Isn’t the “cash” they are holding really Treasury Bills, on which they collect interest?

And weren’t those Treasuries “loaned” to them by the Fed, to keep them afloat?

And doesn’t that make all that cash taxpayer money?

And aren’t they expected to use those Treasuries as collateral against which to buy more treasuries (“monetizing” and therefore to fund the government) on which they collect interest?

Why are taxpayers loaning banks so much money to banks which banks collect interest on, interest that itself is paid by taxpayers?
