Natural gas inventories spread
Natural gas prices are inversely related to the natural gas inventories spread. Because of seasonality, the spread between natural gas inventories and their five-year average is more important, as shown in the chart above.
Since 2007, natural gas prices have been in a downturn. During this period, natural gas inventories were above their five-year average. However, during the 2103–2014 winter season, natural gas inventories fell below their five-year average. Natural gas (GASL) active futures rose to $6.14 per million British thermal units (or MMBtus).
