The dollar's falling. Let's translate. From Marketplace, I'm Sabri Beneshore in for David Brancaccio.

The U.S. dollar is down more than 1% this morning. It hit a three-year low. It may be a sign that investors around the world are wondering if our currency is still as safe as they once thought, given President Trump's trade wars and his threats to the independence of the Federal Reserve,
