Is current monetary policy accommodative relative to the medium-run natural rate?
Core argument: The medium-run real natural rate of interest is estimated at approximately 1.5%, above the implied real federal funds rate of 0.5–0.75% derived from a 3.5–3.75% target and 3% inflation, suggesting a somewhat accommodative policy stance.
Short-run estimates of the natural rate track recent economic developments closely but are notoriously volatile and imprecise. Long-run estimates that reflect the expected natural rate after temporary economic pressures fade are more stable but provide limited guidance for current policy decisions. I propose a medium-run measure that averages short-run natural rate projections into the future, putting more weight on fluctuations up to five years ahead. The medium-run natural rate estimate captures the lowest points of economic activity, known as business cycle troughs, in the early 2000s, the 2008 financial crisis, and the 2020 pandemic. During the 2008 financial crisis,the medium-run natural rate fell nearly 5 percentage points in the first year, driven primarily by persistent disruptions from the financial crisis. The current estimate of the medium-run real natural rate is approximately 1.5%. With the federal funds rate target at 3.5 to 3.75% and inflation hovering at 3%, the implied real rate of 0.5 to 0.75% is below the natural rate, which suggests a somewhat accommodative monetary policy stance.
