Energy prices, like oil and natural gas, can impact stock markets in countries like Russia, Turkey, Brazil, and India. A study looked at how changes in oil and gas prices affected stock indices in these countries from February 2020 to December 2021. They found that Brent oil and crude oil prices had a significant impact on stock indices, but natural gas prices did not. The study also showed that the stock indices influenced the oil prices in some cases, creating a complex relationship between energy prices and stock markets.
