Abstract

This paper analyzes the correlation and evolution of representative European Union stock market indexes from the energy sector, including from the green energy sector against RTS Oil & Gas (RTSOG) a Russian index composed of 11 companies from the oil and gas sector during the double crisis (COVID-19 pandemic and war) and war period. From the impulse response function to RTSOG, high volatility is found present, however with a delayed effect, in the month following the start of the war with BET_NG recording the biggest decrease which could be explained by Romania’s proximity to the war. From all the indexes analyzed, ERIX (renewable energy) is the only one that has the most delayed effect and it becomes rather stable starting earlier than the other indexes analyzed. The variance decomposition results of the indexes explained by RTSOG provide proof of a higher variance level during the double crisis period than the war period.
