Oil Price Movements
By Ian
Via Econopundit I saw this post over at Powerline. Thought it was interesting to look at, so I figured I'd look at a few past years. I've neglected 2003 since Powerline's graph includes some of it, and because the Iraq war introduces an issue that I wanted to sort of skirt around because of time constraints on my end.
Here are the calendar year movements for prices for 2000 -- 2002, all nominal dollars. It's less that I've not got time to adjust the dollars, but more that I was only really interested in the pattern of the movements. (Note: all seasons discussed in terms of Northern Hemisphere -- not meant as a slight to any Southern friends stopping by the site.)

Hmm. That looks a little like we might expect for a seasonal movement in energy. The summer travel season increases demand, while the climb post 11/4/00 might correspond to similar concerns about heating oil supplies we've heard about on the news in relation to current price movements. Possibly a reduction in travel, and potentially the level of oil stocks helped the decrease late in the year.

Summer here is relatively flat. But again we do see that there is some price easing when moving through the late months of the year.

And again a slight increase during the summer into fall, with a reduction in price preceding/entering winter. The difference here, of course, is a marked upturn at the end of the year. Now, what is it that might have occured in late 2002 that made people anxious about oil and oil-producing regions?
The upshot: I'm not terribly convinced that oil prices have moved along with the US campaign for the presidency. Seeing significant movement after controlling for the seasonality of oil prices (that summer is a big time for travel and trasportation -- the biggest sector of oil use -- corresponds to a heated time for the election strikes me as pure conincidence) would do more to sway me towards "conspiracy!!!".
