USGC butane spikes to 4-year high on strong export demand

Strong export demand for butane pushed prices in the Mont Belvieu, Texas, NGL storage and fractionation hub to a four-year high Tuesday, market sources said.

July non-LST butane, reflecting prices at the Enterprise facility in Mont Belvieu, spiked 9.5 cents to $1.40/gal.

Butane was last assessed higher on February 19, 2014, at $1.41/gal. At that time, crude futures were trading at $103.31/b, putting butane at about 57% of crude. In contrast, NYMEX August WTI settled at $68.52/b Tuesday, putting butane's relative value at 86% of crude futures.

Butane averaged 69% of crude over the first three weeks of July, but spiked to 81% on Monday and strengthened further Tuesday.

Most market sources contacted Tuesday pointed to growing exports of butane for the more than 21-cent price swing since Friday.
