Yesterday physical natural gas delivered at the Henry Hub trading point hit its lowest cash price in 21 years–since December 1998. Cash Henry Hub settled at $1.38/MMBtu (million BTUs, the equivalent of Mcf or thousand cubic feet). The Columbia Gulf mainline trading hub (in Louisiana) plunged to $1.285/MMBtu. Right here in the Marcellus, the Transco Zone 4 price fell to $1.36/MMBtu. They all hit their lowest settlement levels since 1998. Why? Blame it on LNG.
