Natural gas futures jumped to a 10- month high after a government report showed that U.S. stockpiles increased less than expected last week.
Gas futures rose 3.6 percent after the Energy Department reported inventories rose 83 billion cubic feet in the week ended May 27 to 2.107 trillion cubic feet. Analyst estimates compiled by Bloomberg showed an expected gain of 94 billion. Hotter-than-normal weather last week may have increased the use of gas to generate power for air conditioning.
“The number was low,” said Kyle Cooper, director of research at IAF Advisors in Houston. “We had some heat across the country last week, and the weather forecasts are still supportive.”
Natural gas for July delivery rose 16.5 cents to $4.794 per million British thermal units on the New York Mercantile Exchange, the highest settlement price since July 30. Futures touched $4.859, the highest intraday price since Jan. 24.
The stockpile increase was smaller than the five-year average gain for the week of 99 billion cubic feet, department data show. A deficit to the five-year average widened to 2 percent from 1.3 percent the previous week.
