The US Dollar Index (USDX) is a measure of the value of the US dollar relative to a basket of currencies. It is considered a benchmark for the US dollar’s performance against other major currencies and can be used to track changes in the global economy. The index was developed in 1973 and has since become an important indicator of US economic health.

The USDX reflects the strength of the US dollar by taking into account a weighted average of six world currencies, including Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc. These six currencies together make up more than 80% of global foreign-exchange reserve holdings—so when they strengthen or weaken against each other. It affects how much buying power the US dollar has compared to them.

Simply put, when the index values goes up, it means that the US dollar is gaining strength relative to these other currencies; conversely. If it goes down, then it means that other currencies are outperforming or gaining value against it. This information provides insight into how international investors view American currency and invest their funds.
