The aim of this paper is to examine the volatility
spillover between bitcoin, gold and crude oil returns. (VAR) Model and three
Multivariate GARCH Models (CCC-GARCH, BEKK-GARCH and DCC-GARCH) estimation
techniques are applied using daily data from 1st January 2011 to August 31th,
2018. Further, these estimation results are used to analyze the relationship
and the volatility spillovers among bitcoin and these commodity currencies. The findings reveal that the bidirectional spillover
is confirmed between gold return and crude oil return. Low unidirectional spillover; from bitcoin return to gold return and from bitcoin to crude oil. We also notice that the DCC-GARCH
model provides a better fit than the CCC-GARCH model and the BEKK-GARCH model. These findings have significant implications for both cryptocurrency
these commodity currencies allocations and portfolio management.
