Is the role of precious metals as precious as they are? Revisiting the role of precious metals for the G-7 stock markets: A multivariate vine copula and BiVaR approaches.
Résumé
This paper revisits the international evidence on hedge, safe haven and diversification
properties of precious metals, namely; gold, silver and platinum for the G-7 stock markets
whereas most of the studies have focused only on gold properties. Conversely to the studies in
the literature that use only bivariate copula, we use the multivariate vine copula based
GARCH model. We then find that precious metals have valuable hedge and safe haven roles
with different degrees. Our findings show that gold is the strongest hedge and safe haven
asset, in almost all the G-7 stock markets. For silver and platinum, results show that they may
act as weak hedge assets. Also, silver bear the potential of a strong safe haven role only for
Germany and Italy stock markets. However, platinum provides weak safe haven role for most
developed stock markets. Using the Bivariate VaR risk measure, we suggest that precious
metals may offer diversification benefits in the G-7 stock markets.
