Episode notes
Why The Dollar Is Falling Now
- The dollar fell to its weakest in four years amid rising deficits, Fed independence worries and trade frictions.
- These political and fiscal issues have pushed investors away from the dollar despite strong US growth forecasts.

- Trump-era policies, especially on trade and pressure on the Fed, catalyzed dollar weakness by increasing policy uncertainty.
- Multilateral trade frictions erode the US advantage in global supply chains and reduce demand for dollars.

- Those negatives mattered less until policy uncertainty made investors care more about the deficits.
