Monetary policy impacts euro area industries asymmetrically
A Banca d'Italia working paper finds that monetary policy shocks transmit asymmetrically across euro-area manufacturing industries. Contractionary actions generate larger and more persistent declines in output and prices than expansionary shocks.
Contractionary shocks dominate
A Banca d'Italia working paper by Marco Flaccadoro and Tiziano Ropele reveals significant asymmetries in how monetary policy shocks affect euro-area manufacturing.
Using monthly data from 2003 to 2024 and externally identified ECB monetary policy shocks, the study employs nonlinear local projections.
It finds that contractionary policy actions cause large and persistent declines in both manufacturing output and producer prices.
In stark contrast, expansionary shocks generate considerably weaker and often short-lived responses.
These pronounced directional asymmetries are consistent across various manufacturing industries and are quantitatively important, with the impact of monetary policy predominantly driven by tightening measures.
The research further highlights that tightening effects are amplified in sectors characterized by greater financial fragility and stronger exposure to interest-sensitive demand.
Industry-specific vulnerabilities
The paper highlights significant heterogeneity in responses across industries.
Intermediate and capital goods sectors face stronger, more persistent contractions from tightening, while consumer goods respond more moderately, with durables showing greater sensitivity.
Price adjustments are also asymmetric, with upstream industries reacting faster.
The study identifies key mechanisms: financial fragility, internal liquidity, pricing capacity, and demand sensitivity.
Industries with higher leverage experience larger output and price declines from contractionary shocks, consistent with credit channel amplification.
These mechanisms are notably more potent following tightening than easing, explaining the observed asymmetries.
The uneven hand of policy
This research provides crucial granular insights into monetary policy's real-world impact.
It underscores that central bank actions are not uniformly felt, with tightening having a disproportionately larger and more targeted effect.
Policymakers must integrate these sectoral and asymmetric dynamics to refine their models and ensure effective, equitable economic stabilization.
