There is also nothing to say they can't lower the funds rate should conditions warrant, as unlikely as that may be.
Perhaps a reminder to those who are younger - the past 10 years have been an aberration and not the norm when it comes to interest rates. The US and world economies have had long periods of growth with 10 year rates of 6% or higher. The current moves are as much about current inflation as they are cover for a Fed that has been looking for a way to end the mistake of ZIRP without actually saying it was a bad idea.
Think of an economics equilibrium as a guitar string. The harder you pluck it (shock) the longer if vibrates back and forth before reaching equilibrium. Plucking it softer but more often, keeps the string closer to equilibrium across the entire time horizon.
This also applies to things like minimum wage increases.
They should have avoided the steep lockdowns and given cash directly to households instead of the giant infusion/bailout to failing states and companies that didn't even need the money.
The piece meal, drip drip increases just raises uncertainty for consumers and businesses while ensuring they are "behind the curve"
