- The Fed chairman told the Senate Banking Committee that officials will not hesitate to act if necessary to keep price pressures in check. "If we need to raise interest rates more in the future, we will," he said. Noting that the economy was in a much stronger position than the last time the central bank reduced its balance sheet, Powell stated that no decisions had been made, but that the process would be much faster this time.

- Powell's comments follow those of other officials who advocate for the Fed to begin shrinking its $8.77 trillion balance sheet soon after it begins raising interest rates. Previous experience has shown that how the Fed manages its balance sheet matters, though the US central bank has also adapted, creating two standing repo facilities in July 2021 to help ease money-market pressures during times of stress.
