Last week’s natural gas inventory data
According to data from the EIA (U.S. Energy Information Administration) released on March 9, 2017, natural gas (UNG) (FCG) (DGAZ) inventories fell by 68 Bcf (billion cubic feet) during the week ending March 3, 2017.
Natural gas inventories and prices
Natural gas prices are impacted by the spread between natural gas inventories and their five-year average. Over the past ten years, whenever natural gas inventories have been higher than their five-year average, prices have fallen.
In contrast, between December 2013 and April 2014, when inventory levels fell short of the five-year average by the highest amount in the past ten years, natural gas prices rose to $6.14 per million British thermal units.
The downturn in natural gas prices since June 2008 could be linked to higher inventories compared to the five-year average.
Recent natural gas inventories and prices
Last winter, natural gas usage for heating was weak due to mild temperatures. At the end of March 2016, US natural gas inventories were at 2.5 trillion cubic feet—67.0% higher than the levels in 2015 and 53.0% higher than the five-year average. As a result, natural gas futures hit a 17-year low of $1.64 on March 3, 2016.
At the start of the injection season on April 1, 2016, the spread between natural gas inventories and their five-year average was at the highest level since April 2012.
However, the spread narrowed in the following months. In the week ending on December 16, 2017, inventories fell below their five-year average for the first time in 19 months. Natural gas active futures prices rose 52.4% between April 1, 2016, and March 15, 2017.
The spread reversed in the week ending on January 27, 2017. During the week ending March 3, 2017, natural gas inventories were at 2,295 Bcf—18.8% more than the five-year average. In the six weeks since the reversal, natural gas prices have lost 12.1%. However, inventories are 7.7% lower than the level last year, which should ensure that prices don’t fall to lows seen last year.
It will be interesting to see the impact of the EIA’s inventory data for the week ending on March 10, 2017. The data will be released on March 16, 2017. Analysts’ estimates suggest a fall of 60 Bcf in natural gas inventories for the week ending on March 10, 2017.
