Abstract

This paper investigates the reasons behind the resilience of the U.S. economy despite the rapid and significant monetary policy tightening since 2022, focusing on two perspectives: heterogeneity among GDP demand components, and the time-varying nature of the credit channel. Methodologically, we employ a Factor-Augmented VAR model to examine the heterogeneity in the effects of monetary policy across demand components. Subsequently, we estimate a smooth-transition Local Projection model with the excess bond premium as a transition variable to quantify the time-varying effects of monetary policy depending on financial market conditions. The analysis reveals that demand components with higher reliance on borrowing are dampened by rate hikes, while components with lower reliance exhibit muted responses. Furthermore, the results show that the effects of monetary policy intensify for demand components with higher borrowing dependence only when the credit channel is strongly operative. Conversely, components with lower borrowing dependence demonstrate weak reactions irrespective of the prevailing regime. These findings suggest that the limited downward impact of the monetary policy tightening since 2022 on the real economy can be explained by the heterogeneity in responses among demand components, the "composition effect" linked to the growing recent dominance of service consumption in the U.S. economy, and the "regime effect" characterized by the subdued amplification role of the credit channel during this period. This paper contributes to the literature by providing a unified framework to analyze both composition and regime effects.
