NEW YORK ( InvestorPlace) -- Since rebounding off the panicked "Europe" low in early October, crude oil is up 35% while the U.S. Dollar Index is up 1.7%.
Often, crude oil rallies have been associated with dollar selloffs, giving credibility to the idea that a falling dollar tends to boost the price of crude oil.
Still, those are long-term strategic considerations. From a short-term tactical perspective, we have geopolitics and seasonality driving the price. There always are issues in the Middle East, and Iran has been in the news (again!), resulting in a perfect storm right in the middle of driving season. It is entirely possible to see a rather large spike this summer, with or without a dollar selloff, with driving season and seasonality kicking in. (Most people refer to the dollar exchange rate using the U.S. Dollar Index, in which the euro -- clearly a problematic currency -- has a 57% weighting. A better gauge is the Trade-Weighted Broad Dollar Index, thanks to its broader composition, including BRIC and other currencies.)
Cracks Spreads Are on Crack!The layman's definition of a refining crack spread is the level of profitability per barrel of oil. This profitability is seasonal, and you can't do anything about that.
