U.S. Dollar Index – USDX

The US Dollar Index is the value of the US Dollar as measured against a trade-weighted basket of foreign currency.

The index measures the upward and downward movement of the US Dollar in the currency market against the Euro, Japanese Yen, Canadian Dollar, GBP, Swiss Franc and Swedish Krona.  While the U.S. Dollar Index measures the daily value change of the US Dollar, it also measures the change in the value of the US Dollar against the currency basket over time.  When the USDX was created in 1973 the index was set at 100.  The USDX number today represents the US Dollar’s rise or fall as compared to the original value of a baseline of 100.
