[1/3] Federal Reserve Board Chairman Jerome Powell speaks during a news conference following the announcement that the Federal Reserve raised interest rates by half a percentage point, at the Federal Reserve Building in Washington, U.S., December 14, 2022.
The Fed's policy rate, which began the year at the near-zero level, is now in a target range of 4.25% to 4.50%, the highest since late 2007.
In the U.S. Treasury market, which plays a key role in the transmission of Fed policy decisions into the real economy, yields were little changed.
"It's not as important how fast we go," Powell said, noting the bigger question facing policymakers is where the endpoint of the Fed rate hikes is and how long it stays at that level.
Any debate over easing rates would only happen when officials are confident inflation is moving down, he said.
