Many European energy companies are profiting from the rise in prices, but there are large discrepancies across the industry.
Those which produce gas or generate electricity using renewables or nuclear — where input costs have not risen — should be making large profits. But those reliant on burning gas for electricity generation are more likely to struggle — especially if they have been cut off from Russian supplies.
Companies’ need to post additional collateral does not mean trades or hedges are unprofitable, but their positions — often linked to providing gas or power to households and businesses — have rapidly become much more expensive to fund.
Companies are struggling to increase their short-term borrowing facilities quickly enough, risking a cash squeeze.
Jakob Magnussen, chief credit analyst at Danske Bank, said the big issue for electricity generators was the need for additional short-term funding.
To hedge their sales generators will normally short electricity futures contracts until the point they actually produce and sell the power into the market, helping guarantee the price they will receive.
But power prices have risen so rapidly in recent weeks that paper losses on the futures contracts have soared, requiring huge amounts of additional collateral to be posted with the exchanges.
“Margin calls are really exploding right now, it’s particularly an issue for smaller utilities,” said Magnussen. “Once the contracts mature and the utilities sell the power they will get their money back, but there’s a huge need for additional short-term funding in the meantime and many banks could be reluctant to increase their exposure so rapidly to the sector.”
