Deciphering the Disinflation Process

Author

Abstract

U.S. inflation surged in the early post-COVID period, driven by several economic shocks such as supply chain disruptions and labor supply constraints. Following its peak at 6.6 percent in September 2022, core consumer price index (CPI) inflation has come down rapidly over the last two years, falling to 3.6 percent recently. What explains the rapid shifts in U.S. inflation dynamics? In a recent paper, we show that the interaction between supply chain pressures and labor market tightness amplified the inflation surge in 2021. In this post, we argue that these same forces that drove the nonlinear rise in inflation have worked in reverse since late 2022, accelerating the disinflationary process. The current episode contrasts with periods where the economy was hit by shocks to either imported inputs or to labor alone.
