Abstract

Amid the global supply chain pressure (GSCP) and economic policy uncertainty (EPU), the prices of energy transition metals (ETM) are significantly interrupted; however, their impacts are asymmetrical across the different minerals and metals. Our study elucidates the asymmetric influences of GSCP and EPU on ETM prices for nine minerals and metals, particularly copper, aluminium, platinum, gold, lead, nickel, silver, tin, and zinc. This study employs the quantile-on-quantile regression (QQR) approach using the monthly data from 1997 to 2023 for empirical analysis. After inspecting the nonlinear data trends, stationarity properties, and cointegration relationships, this study estimates the QQR slope coefficients. The outcomes reveal that EPU and GSCP contribute to increased ETM prices across nine minerals and metals. The effects are minimal at lower quantiles and gradually increase at higher quantiles. The study confirms the authenticity of QQR estimates in robustness analysis. Overall, our results suggest supply chain resilience and coordinated economic policies to control the fluctuations in ETM prices.
