DXY (Dollar Index)

The DXY (Dollar Index) measures the strength of the U.S. dollar compared to a basket of six major foreign currencies—mainly the euro, yen, and British pound. Think of it as a report card for the dollar's overall health in global markets. You'll see it mentioned in financial news because a stronger dollar affects everything from stock valuations to commodity prices to how much American companies earn overseas. When the DXY rises, the dollar is strengthening, which can make U.S. exports more expensive for foreign buyers but makes imports cheaper. For example, if the DXY jumps 5%, multinational companies might see their international earnings shrink when converted back to dollars, potentially impacting their stock prices.
