- Is connectedness between commodity volatility indices and G-7 stock market returns the same across return quantiles?Publication . Hanif, Waqas; El Khoury, Rim; Hadhri, SindaThis study examines the connectedness and spillover effects among G7 stock markets, oil and gold volatilities from January 1, 2017, to June 16, 2022. By employing an in-quantile spillover approach, the study contributes to the existing literature by providing a comprehensive analysis of the linkages between these markets. The findings reveal that spillover effects are highly dynamic and vary significantly across different quantiles of the return distribution. During periods of market turbulence—such as the Covid-19 pandemic, trade tensions, and geopolitical conflicts—spillover intensity increases, indicating heightened market interdependence. The Japanese stock market and Gold volatility index (GVX) consistently act as net recipients of shocks, whereas the stock markets of Canada, France, Germany, Italy, the UK, and the USA serve as net transmitters. While long-term diversification opportunities appear limited, gold and oil exhibit effective hedging properties for short-term investors across various market conditions. From a policy perspective, these findings underscore the importance of monitoring market interdependencies, particularly during crisis periods. Policymakers should implement coordinated strategies to mitigate systemic risks in financial markets, especially in times of heightened uncertainty. Investors should consider short-term hedging strategies using gold and oil to minimize risk exposure during market downturns. Furthermore, financial regulators in G7 countries should enhance surveillance mechanisms to preempt excessive spillovers that may threaten financial stability.
- Quantile spillovers and connectedness between oil shocks and stock markets of the largest oil producers and consumersPublication . Hanif, Waqas; Hadhri, Sinda; El Khoury, RimThis study explores the connectedness between major oil-producing and consuming countries' stock markets (United States, China, Russia, India) and different oil shocks categorized as demand, supply, and risk shocks, following Ready's (2018) framework. Employing a quantile-based connectedness approach and quantile cross-spectral dependence, our analysis spans from July 02, 2007 to May 31, 2023, encompassing diverse market conditions and events. These methodologies help identify interdependence patterns in extreme market scenarios at different time intervals. Key findings show variations in how these stock markets respond to oil shocks, depending on market conditions and quantiles. Demand-related shocks have the most significant spillover effects on the United States, Russia, and India, while risk-related shocks dominate as transmitters of shocks to the United States, China, and India in median quantiles. Market interconnectedness strengthens during extreme market conditions, reflecting historical events. Additionally, bearish markets offer diversification opportunities between these countries and crude oil. This study emphasizes the need for tailored investment strategies, monitoring global oil demand trends, dynamic portfolio management, crude oil inclusion in portfolios, and proactive responses to market players and geopolitical events. These insights benefit investors and policymakers seeking to optimize strategies in the interconnected global financial landscape.
