Too bad we can't dump these losers like the British dumped the EU and Trump dumped the GOPe. It is completely idiotic to believe that the "natural" rate of interest is anything other than what a free market says it should be. Sure there will be irrational exuberance affecting the rate but that quickly corrects itself.
The natural interest rate, or neutral rate as she called it, is an unobservable, theoretical interest rate that is supposed to define a long-run equilibrium that would keep the economy operating at full employment with stable inflation.
Boneheads. There's no such thing even in theory. The price of money in a free economy will rise or fall with the economic outlook. Jury rigging the rate does not change the economy or the outlook, it merely distorts the economic signal that the market rate would have provided. So intead of the necessary deflation or inflation or whatever the economy needs at the moment the rates cause the perversely opposite effect.
In 2008 we needed rates to rise substantially to unwind the bubble quickly and efficiently. Instead the idiots lowered rates which cause the unwind to continue to the present day and beyond. It is in slow motion preventing the subsequent recovery.
Idiots arrogantly think they can control it all.
They have overcontrolled and set up a crash condition.
