•Portfolio risk evaluation and risk spillovers between precious metal and currency markets are assessed.•The DECO marginal model and the spillover index of Diebold and Yilmaz (2012, 2014) are used.•We find weak average conditional equicorrelations among the markets excluding the GFC period.•Precious metals (except platinum) and exchange rates (with few exceptions) are net shock receivers.•Precious metals provide strong risk and downside-risk reductions.
This study examines portfolio management and risk spillovers between four major precious metals (gold, silver, palladium and platinum) and 20 important U.S. exchange markets. To this end, we employ the multivariate DECO-GARCH model and the spillover index developed by Diebold and Yilmaz (2014, 2016) to examine the spillovers between those metal prices and the exchange rates and design portfolios and hedging strategies using different risk measures. The results show evidence of weak average conditional equicorrelations among the considered markets over time, excluding the turbulent 2008–2010 period. Furthermore, the precious metals (excluding platinum) and the currencies (with the exception of the Australian, Brazilian, Denmark, Euro, Mexican, Norwegian, New Zealand and Swedish currencies) are net receivers of shocks. Finally, the four precious metals provide strong risk and downside risk reductions, underscoring the usefulness of including precious metals in a traditional foreign exchange-dominated portfolio.
