Decreasing transaction settlement times increases the effective inflation rate without a Federal Funds Rate Reduction. To maintain a margin of safety against future events, reduce transaction times by the equivalent effective federal funds rate. Efficient money is needed to maintain a smaller supply relative to ex-us currencies without slowing the economy. The reduction in transaction settlement times decreases friction in the money supply, increasing money velocity and maintaining reserve currency status without exchanging growth using the same money supply.
