Abstract

In this paper, we forecast monthly realized volatility (RV) of the oil price based on an extended heterogenous autoregressive (HAR)-RV model that incorporates the role of the El Nino Southern Oscillation (ENSO), as captured by the Equatorial Southern Oscillation Index (EQSOI). Based on the period covering 1986:01 to 2020:12 and studying various rolling-estimation windows and forecast horizons, we find that the EQSOI has predictive value for oil-price RV particularly at forecast horizons from two to four years, and for rolling-estimation windows of length four to six years. We show that this result holds not only based on standard tests of out-of-sample predictability, but also under an asymmetric loss function.
