"The level to which we raise rates is a separate question from the speed at which we move," Federal Reserve Chair Jerome Powell said Wednesday in explaining the central bank's decision to pause rate hikes at its June meeting. It may "make sense" for the Fed to raise rates at a "more moderate pace" than it has in the past 15 months, he said.

Powell said the biggest U.S. banks are "very strongly capitalized," are competitive globally, and are near the top of the league tables. 10:36 AM ET: The Fed should have a strong role in regulating stablecoins, Powell said.
