What will the US FED do after rejecting negative interest rates policy?

Since the US Fed controls the money supply in the US, it will print excessive monies to flood the US monetary system to supersede the negative rates policy.

I do not see any other way for the US except to print monies since it has rejected negative rates policy.  Excessive monetary printing will cause massive USD devaluation.

The consequence of this excessive printing will be hyperinflation which worries me.  I did raise this concern in March 2020.

High inflation without any economic growth will cause stagflation which is very difficult to resolve for any brilliant economist.  The US farmers have already started to destroy their own crops, kill their own animals, and pour away their milk which will affect the supplies of food and push up the prices after the lockdown.  Consequently, the US Fed will be pouring fuel at the current simmering fire with its impending monetary printing action.
