Fed Chair Jerome Powell made clear that interest rates will remain elevated until inflation is under control.

The Federal Reserve chair signaled on Thursday that the central bank will keep raising interest rates in order to convince the American public that it is serious about bringing soaring price growth back to normal levels.

The public sees higher inflation as the norm if inflation stays well above target, according to Mr. Powell. The history cautions against premature easing of policy.

In recent appearances, Mr. Powell has emphasized the Feds commitment to bring down inflation. In a speech in Jackson, Wyo., last month, Mr. Powell signaled that the Fed would continue to raise interest rates.

Mr. Powell saidRestoring price stability will take some time and requires using our tools forcefully to bring demand and supply into better balance Higher interest rates, slower growth and softer labor market conditions will cause some pain to households and businesses.

Mr. Powell explained the rationale behind the speech he gave last month at the Jackson Hole economic conference. He said that the Fed has responsibility for price stability.

We will keep at it until the job is done, Mr. Powell said.

The Fed is expected to raise rates by three-quarters of a percentage point at its next meeting after other Fed officials echoed Mr. Powell's resolve.
