This chart of West Texas crude prices vs Brent north sea crude prices was done a few days ago, with the spread subsequently narrowing further to under $10.
As previously discussed a few weeks ago, with the Strategic Petroleum Reserve release initiated by President Obama now winding down, the glut in Cushing that looks to have caused West Texas crude prices to fall to about a $25 discount to Brent crude and world prices in general looks to be coming to an end. Additionally, to help ensure it doesn’t happen again, it was announced the flow in a large pipeline will soon be reversed to allow crude to flow out of Cushing.
As a consequence the WTI price has been rising steadily and looks to me to be reconverging with Brent prices.
And seems to me, watching the news broadcasting, the increase is at best very disconcerting to the US consumer in front of the holiday shopping season.
