The U.S. dollar has remained relatively strong in 2026, but softer economic data, fiscal concerns and uncertainty over Federal Reserve policy are giving investors more reasons to question whether those gains can continue.
The U.S. Dollar Index, which measures the greenback against six major currencies, is up about 1.15% this year after reaching a 52-week high of 101.80 on June 24. It was trading around 99.4 early Wednesday.
