I am trying to understand some of the factors that cause fluctuations in oil prices and started to think about there relationship with the currency markets. I am having trouble figuring out whether it is oil prices that affect currency markets or if it is the currency moves influence oil prices. I was thinking more that short term swings in oil prices can be caused by changes in currency markets but longterm it is more fundamentals that would influence oil prices and those changes would hen influence long term changes in currency markets. I was wondering what others thought and if i am missing anything. Thanks
