US Dollar Hits Four-Year Low After Worst Losing Streak Since April

The US dollar just posted its steepest four-day decline since April, with the dollar index falling 2.6% and dropping near its lowest level in four years.

According to analysts, uncertainty surrounding the Trump administration's policy decisions is driving the slide. Markets tend to react negatively when the direction of trade, tariffs, or fiscal policy remains unclear—and that uncertainty appears to be pulling the dollar down.

The Federal Reserve wraps up its two-day policy meeting Wednesday and is widely expected to hold interest rates steady. Rate holds typically support the dollar, so traders will be watching whether the Fed's decision provides any stabilization after this week's losses.
