This study explores how global geopolitical risk shocks influence inflation across various economiesfor the monthly data 2003M1-2023M9. Using a structural vector autoregression model, we analyze the impact of global geopolitical risks while controlling for global oil prices, national industrial production, national nominal effective exchange rates, and national policy rates. In the long term, empirical results reveal that a one standard deviation shock in global geopolitical risks increases inflation (by 1.14%) for the pooled sample of advanced economies, (by 1.38%) for the pooled sample of European Union, and (by 0.83%) for the pooled sample of oil- producing countries. In contrast, the results are insignificant for the pooled sample of emerging markets and developing economies, non-oil- producing countries, and the United Sates. A theoretical framework is developed to mathematically demonstrate the transmission of geopolitical risk to inflation through energy and exchange rate channels, providing structural support for the empirical findings. As country-specific inflation tends to follow inflation trends in categories of economies, several policy implications are implemented.
