The U.S. Dollar Index

The U.S. dollar index broadly reflects the dollar's value against the other major world currencies. A drop in this index reflects a drop in the value of the dollar. The dollar mostly rose since the economic crisis began, as it is historically seen as a safe haven in uncertain times. However, since awareness of the U.S. debt situation has been building, the dollar has been persistently trending downward again.

89 was the approximate peak (in March 2009) of the index since the crisis began.
72 was the approximate low of the index in the past year.
