European stocks deepened a monthly rout as disappointing earnings reports reignited investor concern about global growth prospects and oil prices resumed their downward trend.

British wholesale gas prices have fallen over 40 percent in the past year, as mild winter temperatures softened demand amid a sell-off in crude oil markets to which seasonal gas contracts are indirectly linked, and pressure has been mounting on power companies to lower retail prices for households.

“Given the volumes of gas shipped to Europe, the marginal cost of additional Russian gas is low and they should be able to compete with US LNG supplies,” said Malcolm Johnson, a Guildford, England-based faculty member of The Oxford Princeton Programme, an energy training provider. “However, it is clear that in certain countries there is a desire to diversify supplies for supply security.”
