This paper uses bivariate quantile causality nonparametric test and wavelet coherence to analyze the impacts of geopolitical risks and global economic policy uncertainty on global oil market price fluctuations. Quantitative results show that the international geopolitical risk and uncertainty in global economic policy will lead to changes in the international market oil prices. At the same time, not only in the short term, this impact is still significant in the long term. Especially after 2016, the impacts of the double “uncertainty” high-risk events should be monitored closely. •This study examines the impact of “uncertainties” of international geopolitical risks and global economic policy uncertainty on global oil market price fluctuations.•Using bivariate quantile causality nonparametric test and wavelet coherence.•Findings show that the international geopolitical risk and uncertainty in global economic policy will lead to changes in the international market oil price.•The findings are robust for the short as well as long term.
