Federal Reserve Chairman Colin Powell said the rise in inflation is still expected to abate. Even a reduction in bond purchases will increase easing by the middle of next year. As long as the Fed is buying bonds, it is increasing liquidity. The Fed's digital dollar may require congressional authorization. It would be ideal if any central bank's digital currency could be authorized by Congress. It is still believed that the current inflation will subside with the passage of time. It is believed that inflation will fall. Inflationary pressures reflect the mismatch between supply and demand. Supply congestion should be eased before inflation falls.
