What does this research mean for the field?

In the European Union, fiscal conditions shape the strength and timing of inflation pass-through to interest rates, with pass-through being strongest at very low public debt levels and weaker across the central and upper parts of the debt distribution. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To examine how national public debt levels condition the pass-through of inflation into observed interest-rate environments across European Union member states.

Dynamic panel analysis reveals non-linear attenuation of inflation pass-through by public debt across European Union economies, highlighting how fiscal conditions fragment monetary transmission.

Key Points

To examine how national public debt levels condition the pass-through of inflation into observed interest-rate environments across European Union member states.
Analyzed European Union country-year panel data spanning 1999–2024, utilizing dynamic estimations over the period 2000–2024.
Estimated reduced-form dynamic panel models that model smooth variation in inflation pass-through via natural cubic splines on lagged public debt.
Inflation pass-through into short-term interest rates was strongest at very low debt levels and weaker across middle and upper ranges of the debt distribution.
The attenuation pattern occurred predominantly at immediate and short annual horizons and persisted in non-euro and baseline short-rate subsamples.
Euro-area sovereign bond spread specifications failed to replicate the baseline debt-driven attenuation profile observed in short rates.
