. At its start, the value of the U.S. Dollar Index was 100.000. It has since traded as high as 164.7200 in February 1985, and as low as 70.698 on March 16, 2008. The make up of the "basket" has been altered only once, when several European currencies were subsumed by the euro at the start of 1999. Some commentators have said that the make up of the "basket" is overdue for revision as China, Mexico, South Korea and Brazil are major trading partners presently which are not part of the index whereas Sweden and Switzerland are continuing as part of the index.
