Dynamic spillovers across precious metals and oil realized volatilities : Evidence from quantile extended joint connectedness measures

This study examines the nexus between precious metals (gold and silver) and oil (crude oil and heating oil) realized volatilities introducing a novel quantile extended joint connectedness framework combining quantile vector autoregression (White et al., 2015) with the extended joint connectedness approach of Balcilar et al. (2021) using daily data from May 1st, 2006 until June 18th, 2021. Our findings suggest that crude oil is the main net transmitter of shocks in the network across all quartiles. The dynamic total connectedness is heterogeneous over time and driven by economic events. Interestingly, we see that the higher the quartile the more pronounced the net transmission mechanisms of realized volatilities. Notably, the net total directional and pairwise connectedness measures illustrate in most cases similar dynamics
