Index info


The US Dollar Index measures the strength of the US dollar against a basket of six major global currencies, with the euro holding the majority of the weight. It rises when the dollar strengthens and falls when other currencies gain value, making it a key indicator of global economic conditions and investor risk appetite. Because global trade and commodities like oil and gold are priced in dollars, a rising index often coincides with pressure on these markets and on emerging economies, although the relationship is not fixed.
