One of the great things about a global financial collapse is that economic activity slows down so much that people use less oil. And one of the more interesting aspects of this collapse is that despite the terrible problems we face in the U.S., investors are flocking to the dollar as a symbol of permanence in a turbulent world. Since oil is traded in dollars, the combination of a stronger dollar and weaker demand leads to a lower price.

For example, today oil went as low as $86.36 -- which is 41% below its July peak of $147. Meanwhile, the dollar hit a 13-month high of $1.36 to the Euro -- that's 15% stronger than the $1.60 it traded at this summer. That may be because the U.S. passed its $810 billion bailout plan and Europe has not yet figured out what it will do to deal with its financial crisis. Not to worry, oil is still 260% higher than the $24 it traded at in January 2001 and the dollar has lost 48% of its value of $0.92 to the Euro at which it traded back then.

Where do we go from here? That depends on two variables: how much oil-producing nations cut back on production and how the dollar performs relative to other currencies as this global financial crisis unfolds. If oil-producing nations cut back on production, prices will rise as long as the supply contraction matches the decline in demand. And as long as the world perceives that the U.S. is the world's financial safe haven -- the dollar could strengthen. And that would push oil prices lower.

In a nutshell, oil prices will keep dropping unless oil producing nations drastically slash production and the dollar plunges.
