Aug. 25 (Bloomberg) -- Natural gas futures climbed the most in two months on forecasts for above-normal temperatures that would spur demand for the power-plant fuel, slowing the pace of supply restocking.
Hotter-than-usual weather may blanket parts of the eastern and central U.S. through Sept. 3, said MDA Weather Services in Gaithersburg, Maryland. Gas inventories were 17 percent below the five-year average in the seven days ended Aug. 15, the biggest deficit for the time of year since at least 2005.
“The heat in the Midwest is nothing short of oppressive,” said Phil Flynn, a senior market analyst at Price Futures Group in Chicago. “The market is really getting support from the shock of the hot temperatures. We’re going to go into winter with some of the tightest supplies we’ve had in a long time.”
Natural gas for September delivery rose 9.7 cents, or 2.5 percent, to $3.937 per million British thermal units on the New York Mercantile Exchange. The percentage gain was the biggest since June 12. Volume for all futures traded was 10 percent below the 100-day average at 2:45 p.m. Prices are up 13 percent from a year ago.
Net-long wagers on U.S. natural gas climbed in the seven days ended Aug. 19, according to the Commodity Futures Trading Commission’s weekly Commitments of Traders report released Aug. 22. Bullish bets rose 14 percent to 149,608, the first gain since June.
