How does the price of oil influence the value of currency?
Because we need energy in the form of oil.  If more of our money is spent on oil, there is less money to spend on other items especially luxuries like dining out and new cars (ironically) Since there is less money available, the price of other things shift with it and the whole economy moves.  Since less money is available, the value of a single dollar goes up. Basically, it is because we as a species (let alone nations) are unbelievably dependent on having oil at this point in our existence. How do currency markets work? What factors are behind why currencies go up or down?
