Severe cold weather has been boosting energy prices, with a prolonged wave of snow and cold temperatures hitting the East Coast most of the winter.
“Another snowstorm in the U.S. is likely to keep heating demand at a high level and spark a further decline in the already severely diminished stocks of heating oil and natural gas,” said analysts at Commerzbank in Frankfurt in a note to clients.
Optimism that China’s economy is still healthy after credit growth increased in January also helped lift energy prices.
Meanwhile, a new round of talks began Tuesday between Iran and six world powers on finalizing a deal to control Iran’s nuclear program. The outcome could have an effect on oil prices as Iran is a major oil producer and reduction of sanctions would allow the country to export more of its crude.
A weaker dollar also supported oil prices by making commodities like oil cheaper for traders using other currencies. On Tuesday, the euro was up 0.3 percent at $1.3747.
