Natural gas futures slid from a five-week high in New York as meteorologists predicted moderating temperatures that would reduce power demand. Government data yesterday showed that gas supplies rose 67 billion cubic feet in the seven days above the five-year average increase of 66 billion. Gas inventories totaled 3.13 trillion cubic feet in the week ended Aug. 23, 1.5% above the five-year average and 7% below last year’s supplies, EIA data show. The total has declined 12% this year. The U.S. met 87% of its own energy needs in the first five months of 2013, on pace to be the highest annual rate since 1986, EIA data show.
