The US dollar has slid to a three-year low, impacted by a combination of cooling inflation and renewed trade uncertainties, including threats of tariffs. Analysts indicate that this decline is the worst since the 1980s and suggest that a quick recovery is unlikely. The Euro, on the other hand, has surged as the dollar faces pressure due to missed inflation estimates and overall poor economic reports. As traders seek protection against further declines, market focus shifts to interest rate outlooks and ongoing trade negotiations.
