摘要

利用分位数回归方法揭示条件关系,本研究在非洲石油出口国的背景下重新考察了石油库存的共同运动。所采用的数据包括2020年1月2日至2021年5月6日欧佩克原油一揽子价格每日数据和非洲六个石油出口经济体(埃及、加纳、摩洛哥、尼日利亚、南非和突尼斯)股票市场指数的每日数据。我们发现原油不能作为非洲石油出口国股票市场的避险工具。值得注意的是,石油-股票的共同运动是一致的,并且只在较低的尾部更强烈。根据市场情况,政府鼓励投资者将石油作为一种分散投资工具,而不是作为一种避险资产。监管机构应制定战略,加强原油市场,通过缓解非洲股市的下行回报,减少新冠疫情期间的不利波动。这项研究的发现为非洲石油出口经济体的各类投资者和政策制定者提供了更有趣的经济见解。

Assessing the safe haven properties of oil in African stock markets amid the COVID-19 pandemic: a quantile regression analysis
Using the quantile regression approach to reveal the conditional relationships, the study re-examined the oil-stock co-movement in the context of oil-exporting countries in Africa. The data employed include daily OPEC basket price for crude oil and daily data on stock market indices for six major stock markets of oil-exporting economies in Africa—Egypt, Ghana, Morocco, Nigeria, South Africa, and Tunisia, from 02 January 2020 to 06 May 2021. We found that crude oil cannot act as safe haven instrument for stock markets in oil-exporting African countries. Notably, the oil-stock co-movement is consistent and more intense at the lower tails only. Investors are encouraged to employ oil as a diversification instrument rather than as a safe haven asset, based on market conditions. Regulators should devise strategies to strengthen the market for crude oil to lessen adverse volatilities during the COVID-19 pandemic by way of mitigating downward returns in African stock markets. The findings of the study offer more interesting economic insights to all classes of investors as well as policymakers in oil-exporting economies in Africa.
