As I have long argued Reverse Repos were used to unwind QE by selling them in the open market (meaning short bonds). As such we have been tapering for over 8 months now and the yield curve has collapsed. Expect RR to drop when the FED starts to taper going into a slowing economy.
The simple truth is that the market always finds a way to self-correct. The problem often is that Gov't gets in the way of that. This is yet again another fine example. As such #MMT centralized planning cannot and will not ever work. It would only lead to a total collapse.
