Abstract

This paper investigates the hedge and safe-haven properties of green bonds (GBs) performing as a safeguard against oil price shocks and uncertainty, in comparison to the corresponding roles of gold, the 3-month European government bills, and the U.S. 3-Month T. bills. Oil price shocks are disentangled into oil supply, oil demand, and oil risk shocks based on the recent methodology of Ready (2018), generated in a framework that includes gold, oil shocks, and oil uncertainty (OVX). The ability of GBs to protect against oil price shocks and oil uncertainty is examined using the GARCH and quantile regression (QR) models. The results show that GBs are more appropriate than gold and conventional bonds (CBs) as hedging and safe haven tools against oil price shocks and oil uncertainty. Besides, the ability of GBs to protect against oil price shocks and uncertainty depends on whether the oil shocks are supply, demand, or risk shocks. Furthermore, we find that GBs serve as a strong hedge and/or a safe haven against structural oil shocks generally under bearish GBs market conditions. The European government bills and the US T. bills play the role of weak hedge and a safe haven asset against oil uncertainty and oil shocks. This role varies across quantiles (bear and bull market conditions). Relevant risk management implications are discussed.
