Why The Recent Brent-WTI Spread Narrowed

 | Jul 02, 2013 03:10AM ET

For the first time in some 2.5 years Brent-WTI spread has traded around $5/barrel. The two types of crude oil represent nearly the same product but have been trading at a wide spread due to difficulties of transporting sufficient amounts of North American crude from Cushing Oklahoma, where WTI is settled, to the Gulf of Mexico where it could be delivered to major US refineries or shipped elsewhere as a replacement for the more expensive Brent crude. These delivery challenges have been significantly reduced in the past couple of years. At the same time some technical issues in the North Sea have been resolved to stabilize Brent pricing.

Bloomberg : The drop in the gap between Brent, a gauge for more than half the world’s oil, and WTI shows how improved pipeline networks and the use of rail links have helped to unlock a glut at America’s oil-storage hub at Cushing, Oklahoma, in line with a prediction made by Goldman Sachs Group Inc. as long ago as February 2012. WTI rose 5.2 percent in the first half of this year. Brent dropped by 8.1 percent as North Sea supplies have stabilized following oilfield maintenance.

“The spread is coming in on anticipation that we’re going to see pipelines get built and more rail capacity put in place,” said Bill O’Grady, chief market strategist at Confluence Investment Management in St. Louis, which oversees $1.4 billion. “There is now a likelihood that not only will U.S. imports drop further, but that the country will be exporting before long.”

But there is one question that still remains unanswered. A major portion of the spread compression to $5 has taken place just in the past few weeks. Moreover, the volatility of the spread has fallen dramatically.
