Natural gas inventory data
In the week ended June 16, 2017, natural gas inventories rose 61 Bcf (billion cubic feet) to 2,770 Bcf based on EIA (U.S. Energy Information Administration) data released on June 22, 2017.
So far in this injection season, natural gas inventories have risen by an average of 65 Bcf, compared to 57 Bcf during the same period in 2016. An above-average rate of inventory additions could impact natural gas prices adversely.
Natural gas inventory spread
Natural gas (GASL) prices and the natural gas inventory spread usually move in opposite directions, as we can see in the graph above.
In February 2014, natural gas active futures closed above the $6 mark—a multiyear high. In March 2014, natural gas inventories fell more than 50% below their five-year average.
The inverse relationship between the natural gas inventory spread and natural gas prices could be important for the Direxion Daily S&P Oil & Gas Exploration & Production Bear 3x ETF (DRIP), the iShares US Energy ETF (IYE), the Vanguard Energy ETF (VDE), the ProShares Ultra Oil & Gas ETF (DIG), and the SPDR S&P Oil & Gas Exploration & Production ETF (XOP).
