Natural gas in storage increases by a seasonal 88 billion cubic feet to 1,934 in the April 18 week from 1,846 bcf in the prior week as spring and summer injection season continues. Natural gas in storage is down by 478 bcf or 19.8 percent from 2,412 bcf in the year-ago week. Compared with the 5-year average of 1,978 bcf, natural gas stocks in the latest week are down 44 bcf or 2.2 percent.

The Energy Information Administration (EIA) provides weekly information on natural gas stocks in underground storage for the U.S. and five regions of the country. The level of inventories helps determine prices for natural gas products.

Natural gas product prices are determined by supply and demand - just like any other good and service. During periods of strong economic growth, one would expect demand to be robust. If inventories are low, this may lead to increases in natural gas prices. If inventories are high and rising in a period of strong demand, prices may not need to increase at all, or as much. During a period of sluggish economic activity, demand for natural gas may not be as strong. If inventories are rising, this may push down natural gas prices.
