Here is an intriguing headline for you. The diesel crack spread. What is it?
It is the amount of profit you can make from cracking a barrel of crude oil into shorter chain diesel fuel. The current crack spread reached a 30-year seasonal high of nearly $70 per barrel yesterday, compared to the less than $20 per barrel this time last year. Worse, US diesel stockpiles are at the lowest since 2000. Going into the winter season, we’re likely see diesel demand and prices increase as high natural gas prices cause some to switch to diesel in the northeast US.

I can’t imagine diesel prices going in a different direction than gasoline prices, at least not for any extended period of time. Will we be back to $6 gas by Election Day?
Not if a recession comes along and quashes demand for fuel. I think it’ll take longer than to election day, though.
