Dollar Divergence: Yields Soar, Dollar Stumbles in Unprecedented Shift

The US Dollar Index (DXY) has failed to strengthen despite 10-year Treasury yields hitting a two-decade high in October 2025. Typically, higher yields attract foreign capital, boosting the dollar's value.

However, this time around, the rise in yields is driven by concerns over rising government debt and sticky inflation, rather than strong growth expectations. This fear offsets the investment appeal of higher yields, and other central banks outside the US are also keeping rates high, narrowing the interest rate differential that previously favored the dollar.

This divergence suggests that traditional carry-trade strategies may be less effective, and the dollar's strength is more tied to global risk sentiment and fiscal sustainability than to simple yield differentials. The dollar could remain under pressure if the market continues to view the US fiscal trajectory as unsustainable, even with high yields.
