How high is the ongoing US fiscal expansion likely to push inflation? This column presents new evidence that underlying (weighted median) CPI inflation has so far steadily declined since the start of the COVID-19 crisis, broadly as predicted by its historical Phillips curve relation. If the ongoing fiscal expansion reduces unemployment to 1.5-3.5%, as some predict, underlying inflation could rise to about 2.5-3% by 2023. If the fiscal expansion is temporary and monetary policy remains clearly communicated and decisive, there is little risk of a 1960s-type inflationary spiral.
