The study relied on a set of financial variables, including the Brent crude oil index (Brent), the S&P Clean Energy Index, the U.S. Dollar Index (DXY), the Volatility Index (VIX), and the S&P 500 index. To measure volatility dynamics, the EGARCH model was employed due to its ability to capture asymmetric shocks and the leverage effect. The findings revealed that oil markets are characterized by high volatility persistence, with positive shocks exerting a stronger effect than negative shocks, confirming the existence of a limited leverage effect. The study also showed that the transition toward clean energy imposes structural pressures on oil markets by influencing global demand expectations, without leading to a complete replacement of oil in the short run. Therefore, the study highlights the importance of adopting economic diversification policies and integrating climate risks into financial governance frameworks.otherenergy transitionoil price volatilityEGARCH modelfinancial leveragetransition risks.Thesis
