Abstract

In this paper, we examine the volatility and time-frequency connectedness among the financial stress index (FSI), cryptocurrencies namely, Bitcoin, Ethereum, Tether, BNB, Solana, and commodities namely, Gold, Silver, Copper, Platinum, and Brent Oil, using the quantile vector autoregressive (QVAR) frequency connectedness, wavelet coherence, and hedging effectiveness techniques, for the period spanning from June 2020 to December 2023. Findings indicate that the spillover effect among FSI, cryptocurrencies, and commodities substantially varies across different volatility conditions. Also, some cryptocurrencies are net receivers of shocks during normal market conditions, while other cryptocurrencies are net transmitters during extreme market conditions. We also find that, during the bullish market, some commodities (Platinum and Brent oil) are net receivers, while other commodities are net transmitters under extreme market conditions (lower quantiles). Similarly, findings further show that, under extreme volatility conditions (higher quantiles), cryptocurrencies and commodities are net receivers of shocks, while FSI is a net transmitter during these volatility conditions. Using frequency co-movement analysis, we find strong and weak correlations between these series in the short- and long-run for shorter periods. Furthermore, findings provide important implications for policymakers and portfolio managers to pay attention to long-term dynamics and design appropriate policies that mitigate the spillover effects.

期刊介绍: Resources Policy is an international journal focused on the economics and policy aspects of mineral and fossil fuel extraction, production, and utilization. It targets individuals in academia, government, and industry. The journal seeks original research submissions analyzing public policy, economics, social science, geography, and finance in the fields of mining, non-fuel minerals, energy minerals, fossil fuels, and metals. Mineral economics topics covered include mineral market analysis, price analysis, project evaluation, mining and sustainable development, mineral resource rents, resource curse, mineral wealth and corruption, mineral taxation and regulation, strategic minerals and their supply, and the impact of mineral development on local communities and indigenous populations. The journal specifically excludes papers with agriculture, forestry, or fisheries as their primary focus.
