"At this point price stability is still job one. We have to get that out of the way," before worrying about the impact on economic growth, Mester said in comments at an inflation conference at the Cleveland Fed.
"As inflation moves back down, then those decisions become judgments about when do you hold, how long do you hold, when do you move things back down. But right now the focus is on making sure that we've achieved price stability."
Mester said that Fed plans to raise rates to the mid-4% range then hold them there shows the central bank will allow time to see how their policy impacts the economy once policy becomes appropriately "restrictive."
