In his speech at the Jackson Hole economic symposium Friday morning, Powell said the Federal Reserve’s actions to control inflation would bring “some pain to households and businesses.”

He also addressed speculation that indications of a softening of price increases in July might cause the Fed to slow its pace for interest-rate increases by saying he still saw “strong underlying momentum” in the U.S. economy.
