Abstract: We extend the literature on the effect of rare disaster risks on commodities by examining the effect of the El Nino- Southern Oscillation (ENSO) on crude oil via the recently developed k-th order nonparametric causality-in-quantiles framework, utilizing a long range historical data set spanning the period 1876:01 to 2020:10. The methodology allows us to test for the predictive role of ENSO over the entire conditional distribution of not only real oil returns but also its volatility, by controlling for misspecification due to uncaptured nonlinearity and regime-changes. Empirical findings show that the Southern Oscillation Index (SOI), measuring the ENSO cycle, not only predicts real oil returns, but also volatility, over the entirety of the respective conditional distributions. The findings highlight the role of rare disaster risks over not only financial markets, but also commodities with significant implications for policymakers and investors.
