The U.S. dollar slid on Friday and was set for its worst week in over a year after President Donald Trump suggested a softer stance on tariffs against China, adding to uncertainty around the trade policy that kept equity markets on edge.

The dollar fell to a five-week low after U.S. President Donald Trump said he'd prefer not to impose tariffs on China. In an interview with Fox News aired Thursday, he said China doesn't want tariffs and he would "rather not" use them.

The U.S. dollar weakened on President Donald Trump’s Inauguration Day, and remained under pressure Tuesday after it became clear immediate tariffs weren’t in the cards, according to BofA Global Research.
