What's driving the big share price gains?
There are numerous factors that determine a company's share price. But when it comes to ASX 200 energy shares, the price of the fossil fuels they mine from the earth is critical.
And energy prices have been rocketing.
On the supply side, there've been bottlenecks due to pandemic related production issues, storms in the major oil producing Gulf of Mexico, a broad pullback in new exploration over the past 18 months, and a determined OPEC keeping a lid on the cartel members' own output.
On the demand side, while demand for jet fuel remains well below pre-pandemic times, demand for most ground and sea transport is rebounding quickly.
The result?
Brent crude prices leapt from US$71.59 per barrel to US$78.52 per barrel during the month of September. And they've kept edging higher with a barrel of Brent crude currently trading for US$81.26.
Coal is enjoying an even stronger run with demand remaining strong for Australia's high quality coking coal. That's the kind that's used to make steel, as opposed to thermal coal used for power generation.
Coking coal prices have gained some 300% over the past 12 months, reaching record prices of more than US$200 per tonne.
Little wonder then that the leading ASX 200 energy share trounced the index in September.
