Two recent developments could spike
The first is Saturday's devastating derailment of a train carrying a load of crude to an Irving Oil refinery in Canada. The St. John's refinery has the capacity to process 300,000 barrels of crude a day, making it Canada's largest. And most of that refining capacity goes toward making gasoline. The tracks that run these trains were heavily damaged, and officials say it will take weeks or longer to fix them.
The second development is the formation of the season's first tropical storm, Chantal. This in itself has had little-to-no impact on refiner operations, but it does remind traders that it is hurricane season, and you don't want to be caught short when a disruptive storm is coming.
