The confluence of these price movements also brought the ratio between WTI and Henry Hub to a historical record high of 52:1 (see chart below) while the ratio of Brent to Henry Hub is a jaw-dropping 60 to 1! (And we thought the 25 to 1 ratio reached back in August 2009, also a historical high at the time, was parabolic.)

Crude oil and natural gas are both energy commodities and should logically have a high degree of correlation. Theoretically, based on an energy equivalent basis, crude oil and natural gas prices should have a 6 to 1 ratio. However, due to various market characteristics, the price of oil typically had traded 8x to 12x that of natural gas in the past 25 years or so (see chart above). That historical pattern has started to deteriorate since 2009 primarily due to the combination of rising domestic production from unconventional shale gas depressing price levels, while geopolitical events in the MENA region (Middle East & North Africa) adding a fear premium to global crude oil prices.
Natural gas lacks the global market structure like crude oil and tends to be regionally based, and therefore less impacted by external sources. Oil, on the other hand, is a commodity with global demand drivers and along with gold, trades as an inflation hedge against a weakening U.S. dollar.
In most of Europe and Asia, the price of natural gas/LNG is typically linked to crude oil under multi-year contracts. So while the spike in Brent helped to boost natural gas markers elsewhere, with practically zero LNG export capacity in the U.S., not even the Fed's two rounds of quantitative easing could lift the languishing Henry Hub.
The chart below illustrates just how disconnected the U.S. natural gas price is versus price levels in Asia and Europe, and compared to Brent crude oil.

While low prices are killing some of the natural gas producers, consumers will get a break from lower electricity costs. Meanwhile, U.S. natural gas trading at an 87% discount to Brent crude oil price is something even the oil industry appreciates. Valero (VLO), the world's largest independent refiner, said in a presentation this January that its refinery operations use up to 600,000 mmBtus/day of natural gas at full utilization. Betting on "low U.S. natural gas prices for many years to come," Valero has several hydrogen and hydrocraker projects scheduled to complete by the end of 2012 to take full advantage of the low natural gas prices.
Realistically, U.S. gas cargoes may have a hard time competing with other exporters such as Russia, Qatar and the up-and-comer — Australia — in the Asian and European markets due to logistic disadvantage.
For U.S. LNG exports to make economic sense, the domestic gas price would need to stay low, with high enough international LNG prices, and if the LNG prices are still tied to crude oil (which could change depending on market development), then crude oil prices would have to remain elevated.
With the prospect of domestic natural gas prices remaining low and disconnected from global oil and gas prices for the foreseeable future, U.S-based manufacturers of plastics, fertilizers and other products that use natural gas as a feedstock such as Dow Chemicals (DOW), Westlake Chemical Corp. (WLK), Potash (POT) and CF Industries (CF), are set to benefit from cheap U.S. natural gas as opposed to European and Asian competitors who do not.
