Ah, gotcha I see what you are saying.
I think what OP was saying was that in an unrestricted market they have wider range (due to discretion) but given this shackle on hikes, they are going to max it out. Maxing it out means there will not be downward adjustments when warranted (economic trends) and will instead ride it out (not make it avail at lower price) because when the economy picks up they’ll more than make the loss up.
