Abstract: This paper examines the dependence structure and the systemic risk between the return series of oil prices and the BRICS equity market indices, using the newly developed methods of the quantile coherency of Baruník and Kley (2015) and the nonparametric conditional value-at-risk causality (NCoVaR) and the NCoVaR Granger causality tests (NCoVaR-Gc) of Diks and Wolski (2018) for the period 2001–2018. Further, the traditional tests of Hiemstra and Jones (1994) and Diks & Panchenko (2005) are used for comparison purposes. The new methods have given rise to findings that are substantially different from those based on the two traditional approaches. From our frequency-dependence analysis, we find a significant long-term dependence coherency between the Russian, Brazilian and South African stock markets and oil shifts. However, the NCoVaR analysis demonstrates a robust instantaneous dependence in both directions between almost all of the BRICS stock markets (the exception is the Indian market) and the oil market. The NCoVaR-Gc analysis reveals a robust lagged dependence from the oil market onto the Chinese stock market only. These findings provide helpful insights for regulators and potential international investors.
