Natural gas prices declined last week – 18-22 July

Natural gas prices (Henry Hub) inclined very sharply a couple of weeks ago, but this week they have changed direction and fell mainly during the second half of the week. The rise was probably stemmed from high demand for natural gas to the electric sector. The heat wave that attacked the US during the last few days might pull up natural gas prices or at least keep them high, until the high usage of air conditioners will drop.  

Despite the shifts in demand for natural gas, US natural gas storage continues to stock up.

 Here is a short review of the main changes in natural gas prices for the week ending on July 22nd:
