Do gold, oil, equities, and currencies hedge economic policy uncertainty and geopolitical risks during covid crisis?

Abstract

Recent literature extensively studies the safe-haven properties of different asset classes in crisis periods. The magnitude of the economic policy uncertainty index (EPU) and the geopolitical risk (GPR) increases significantly during extreme crisis periods such as covid crisis, but the earlier literature ignores how both risk measures impact on different asset classes during severe economic downturns. In this paper, we contribute by examining the hedging and safe-haven properties of gold, oil, equities, and foreign exchange rates against the United States (US) EPU and GPR by utilizing OLS regression, quantile regression and the quantile connectedness approach for pre-covid (October 1, 2013–March 10, 2020) and post-covid data (March 11, 2020–August 27, 2021). OLS results suggest that only the stock market has positive risk premium for both uncertainty measures. With quantile regression analysis for the pre-covid period, we find that asset returns provide no hedge (hedge) across bearish (bullish) market conditions. Importantly, safe-haven properties suggest that gold is a safe-haven asset at the extreme stress condition (at higher level of USEPU shocks). Other assets also exhibit safe-haven characteristics during extreme uncertain periods with heterogeneity in safe-haven effectiveness across bearish to bullish markets. With the post-covid data, we show that S&P500 stocks and EURO hedge EPU and GPR in bullish market condition, while Oil, S&P500, Great Britain Pound, EURO, Japanese Yen display safe-haven properties at the 99% quantile of USEPU. Specifically, gold lost its safe-haven features during covid. Interestingly, results from quantile connectedness suggest that selected asset returns have the potential to diversify against uncertainty measures considering low volatility transmissions between them across the lower and higher quantiles. Our findings are important for investors and asset managers who aim to hedge EPU and GPR during the stress period.
