The major component of the dollar index is the euro. If the euro goes down the dollar goes up. The dollar isn't really going up; the euro is going down for now.
When the financial difficulties circle around to the US again then the dollar will go down and the euro will go up.
Nothing is measured against a true standard anymore. As long as both entities print money they both remain at a high level; whereas reality dictates they have both fallen.
It is all nonsense.
Even gold isn't a true standard as it is manipulated.
