Abstract: 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.
