Natural gas prices shifted to red again– 15-19 August

Natural gas prices (Henry Hub) changed direction again: after the rises during the previous week, this passing week US natural gas prices declined during most of it. The slightly cooler temperatures in the US eased the demand for natural gas in the electric sector. The sharp falls in the stock market and the concerns in the US over an economic slowdown might have also contributed to the fall in the Henry Hub prices (at least the short term future price). By the end of the week, the Nymex Henry Hub Future Price (September delivery) ended the week on $3.94/ MMbtu.

 Here is a short review of the main changes in natural gas prices for the week ending on August 19th:
