What excess reserves?

Here is is, the so called excess reserves.  Whaddya know, the excess matches the loans on record (red and blue).  Mark Thoma claim s this is unused savings, but then why would unused savings exactly match money lent to the Treasury?

Then Thoma claims the equilibrium rate is unreachable, its negative.  Who's model says the equilibrium rage is unreachable?  If the model mentioned is the MIT Magic Walrus, then  yes, it prints a contradiction because  MIT economists were full of crap and simply made up the Magic Walrus.

Economists, try to make sense.  Mark is mixing models here.  He wants a model that has  single adjustment in the Swamp, but no model exists, and there is no variable change that would make such  model correct.  It is Thoma's model that is a contradiction .
