Abstract

The objective of this paper is to examine the frequency domain connectedness among the returns series of crude oil, stock market index and four metal prices covering the period 1990M1-2017M3. To realize our objective, we have employed a recently introduced frequency domain spillover methods due to Barunik and Krehlik (2017). Furthermore, a network analysis is undertaken on the pairwise correlations and net directional matrix obtained from frequency domain spillover approach. In general, we find that the degree of connectedness decreases with the increase in the frequency. Particularly, with the lowest frequency i.e., 1–6 months, makes the largest contribution to total connectedness, followed by the frequency corresponding to more than 12 months, and 6–12 months, respectively. Our overall results suggest that titanium, platinum, gold and silver are the net contributors to volatility, while steel, crude oil, stock prices, and palladium are net receivers of volatility. These empirical findings are helpful in devising policies that avert contagion risk during period of economic rigidity and uncertainty.
