KEY POINTS
  • Wild trading in natural gas futures drove prices up 18 percent Wednesday to a four-year high on record volume, as the latest cold weather reports spooked a market worried by low supply.
  • The parabolic type of trading could have been the result of traders needing to buy natural gas to cover short positions, and prices could go even higher depending on the weather.
  • The move was the biggest one day jump in years, and natural gas is now up about 48 percent since the start of November.

Natural gas prices surged to a more than four-year high in panicky and volatile trading Wednesday, after the latest cold weather forecasts raised fears that the U.S. is heading for a potentially colder-than-expected winter with too little gas supply.

Futures for December settled up 18 percent at $4.837 per mmBtus but had been up as much as 20 percent in an early morning rush of panic buying. Prices also rose across futures contracts that that would cover the winter months through March, indicating that prices could be pressured all winter by dwindling supply, which is at a 15-year low for this time of year.
