Some critics think the Federal Reserve isn't moving fast enough to respond to high inflation.
Neel Kashkari, president of the Minneapolis Fed, rejected that notion on Friday, saying that the Fed's policy is already making a noticeable impact on sharp increases in long-term interest rates.
However, he also didn't rule out the possibility that the Fed might have to take more aggressive action and raise short-term interest rates more than currently planned, particularly if supplies of goods remain tight.
"Have we moved them enough?" he asked in a talk at the University of Minnesota's Carlson School of Management. "I don't know. It really is going to depend on what happens with some of these supply issues."
He noted that the war in Ukraine and China's more recent pandemic-related shutdowns are placing additional stresses on supply chains.
"If we don't get any help in terms of supply chains normalizing, then we're going to have to do more with monetary policy," he said.
Earlier this week, the Fed's rate-setting committee raised short-term interest rates by a half-percentage point to hopefully help cool off red-hot price increases. That followed a quarter-percentage point increase in March. Fed Chair Jerome Powell said that the committee is planning two more half-percentage point increases at its upcoming meetings in June and July.
That would put interest rates at or near what the Fed considers a "neutral" interest rate, which is a moving target but that in theory neither stimulates nor restricts the economy.
