If you have taken up British Gas's much-publicised offer to cap (they avoid the word 'freeze') its price for the next three years you may be feeling clever.
In a demonstration of markets taking leave of logic, the wholesale price of gas rocketed to 255p a therm from 61p on Monday and was still holding around 220p yesterday.
Much more of this and big energy users - all manner of metal industries and brick-works as well as the vocal chemicals industry - will be working out the harsh economics of whether they stand to lose even more money by shutting down for the duration than by keeping going. National Grid put out its first ever alert of a potential shortage, though yesterday it sounded less alarmed.
So householders who signed up for the British Gas deal can bask in the pleasurable assurance that whatever happens to this dizzy price other people will pay it.
Quite what went wrong is unclear. The cold snap over much of Britain generated the predictable surge in demand -predictable in that much the same thing happened in March last year. But then wholesale gas never ran higher than 120p. When the weather turned unseasonably chilly in November the top price was 170p.
This time, even on Monday, it stopped short at 115p in the Netherlands. With any half-functioning market, some nimble soul would have been coining easy money pumping the stuff into Britain over the Interconnector pipe between Belgium and Norfolk.
Well, if they did it was too little to ease the squeeze in Britain. Centrica, owner of British Gas, said the Inter-connector was not running f lat out. Why was not explained.
On top of that there was a bit of bad luck. A fire has temporarily closed Rough, a big North Sea storage field, French gas workers have been on strike and there seem some worries about Norway's output, too.
None of that is a remotely plausible explanation for gas in Britain costing more than double what it did on the continent. Bad luck doesn't have that kind of impact without somebody rigging the market.
As for British Gas, it didn't offer its capped contract with the intention of exposing itself to open-ended losses. The idea was to give some of its customers second thoughts before they switched to a rival after BG put its prices up by 22 per cent.
There was a decent chance that wholesale gas prices in Britain will fall rather than rise over the next year or two as new facilities for handling hopefully cheaper imported gas start to work. That should still be a decent chance.
The continental market for wholesale gas is a self-evident disgrace. It may well remain so. Huffing and puffing by Euro regulators is never going to beat determined efforts by national Govern-ments and companies to secure their energy supplies. They took note of President Putin's brief suspension of Gazprom's supply to Ukraine and drew the obvious conclusions.
But within Britain the market for supplying gas to households and business is robustly competitive and may very well remain so.
