For example, the dollar crashed 33.6 percent from July 2001 to December 2004. This crash meant that all financial markets denominated in dollars had to go up 50 percent just to stay even in terms of global purchasing power. Gold did better than keep pace, but all the dollar-denominated Dow did was climb back to the same level it was at in July 2001, which means that it actually lost 1/3 of its global purchasing power during this time.
Whenever the dollar rallies, the same forces move in reverse.
