Causality Relationship in Energy Supply Security, Oil Prices and Stock Markets: BRICS-T Example

Abstract

The aim of the study is to examine the dynamic relations between energy markets and financial markets in the center of the concept of energy supply security. In this direction, the stock market index, oil price and international energy security risk index score covering the annual data for the 1994-2018 period for the BRICS-T countries (Brazil, Russia, India, China, S. Africa and Turkey) were used and Toda & Yamamoto to investigate the aforementioned relationship. (TY) and Fourier Toda & Yamamoto (FTY) causality methods were used to analyze the variables. While empirical findings show (i) causality from stock market to energy security risk in all countries except Brazil, and from energy security risk to stock market only in Turkey, (ii) mutual causality between energy security risk and oil price in China and Turkey, however, in Brazil, it shows that there is causality from oil price to energy security risk. The findings thus reveal the importance of financial markets in terms of energy security risk in the energy-finance relationship for BRICS-T countries. This result includes an inference that the uncertainty and risks arising from the financial markets of these countries should be taken into account in their energy security policies.
