Energy supply shock from US-Israeli attack on Iran fuels record valuations for Shell, ExxonMobil and Chevron

Beyond the strait: why attacks on Kargh Island could keep oil prices high

Shares in big oil companies have soared to all-time highs since the war in Iran began and sparked historic price rises on global oil and gas markets.

The combined market value of the six stock market-listed western “super majors” has soared by more than $130bn in the two weeks since the first US-Israeli attacks on Iran.

The energy supply shock caused by the conflict has resulted in record stock market valuations for London-listed Shell, Europe’s largest oil company, as well as US oil companies ExxonMobil and Chevron.
