Abstract

Geopolitical turmoil, such as the Russia-Ukraine war, compels a renewed examination of the interaction and hedging effectiveness between clean and dirty energy assets. While prior studies focus on crude oil prices, we employ oil and clean energy indexes from 24.02.2022 to 07.06.2024, in a novel integrated mean-variance model. Accounting for geopolitical risks, investor fear, and carbon prices, we find oil price surges reduce clean energy returns, with no feedback. The model delivers 70 % hedging effectiveness versus 49 % for the variance-only approach. Findings highlight the reinforcement of oil’s financial role and the weakening of clean energy investment amid global instability.
