What is the significance of Jerome Powell's performance as the head of the Federal Reserve? Will high interest rates remain?

What should we understand from the speech of the Fed Chairman Jerome Powell before the senators today?
According to The Wall Street Journal journalist Nick Timiraos, who is usually considered as the "Fed spokesman", officials are not rushing to lower the Fed interest rates due to the latest inflation data indicating easing price pressures towards the central bank's 2% target.
Federal Reserve Chair Jerome Powell said today at a congressional hearing that the U.S. economy continues to perform well, giving policymakers the ability to make informed decisions about when to lower rates. Earlier, the Fed lowered rates by a full percentage point over the last three meetings in 2024, following a period of historically high rates.
