Natural gas is one of those commodities that economists consider as close to a “pure” commodity as one can get. Meaning the classic supply and demand curve rules. When you get more supply than you have in demand, the price goes down–along a predictable curve. In the natural gas world, supply signals come from a couple of different numbers. One is overall production. Another is storage–how much natural gas is sitting, unused, in underground storage, put there during summer “injection season” so it can be used during the winter “withdrawal season.” The bad news (for prices) is that with relatively mild temperatures this winter, we are at near-record high storage levels, according to the U.S. Energy Information Administration (EIA).
