To this end, the stationarity of the annual Geopolitical Risk Index (GPR) and global inflation series for the 1985–2024 period was first analyzed using the Lee and Strazicich (2003) two-break unit root test, which concluded that the series are stationary at levels. Subsequently, the data were analyzed using a stationary frequency domain causality approach, revealing a unidirectional causal relationship running from GPR to global inflation at both low and high frequencies. The causality identified at low frequencies indicates that this causal effect is permanent. The findings of the study suggest that mitigating geopolitical risks is of vital importance in the fight against global inflation. © 2026 The Author(s).eninfo:eu-repo/semantics/openAccessFrequency Domain CausalityGeopolitical RiskGlobal InflationArticle17258258810.14505/tpref.v17.2(38).192-s2.0-105043696007Q4
