Natural gas futures surged nearly 3 percent on bullish supplies data Thursday to reach an intraday high of $4.335 per million BTUs, the highest price for a front-month contract since July 2011.
The U.S. Energy Department reported natural gas supplies rose by 31 billion cubic feet last week, the first increase in storage so far this year. Still, the supply increase fell short of analysts' expectations and was also lower than the five-year average.
Tim Evans, energy futures specialist at CitiFutures, said that the natural gas supply data "was supportive relative to consensus expectations, suggesting a slower tapering off of heating demand than had been anticipated."
