Josh Landis and Mitch Butler of the "Fast Draw" team take a close look at what determines the price of oil and the impact price fluctuations have on the overall U.S. economy. The main factor driving up the prices is falling value of the U.S. dollar. Since 2001 the value of the U.S. dollar has been plunging against currencies like the Euro. Speculators also help to drive up oil prices.
