Dollar Soars as Fed Hikes Interest Rates and Flattens Yield Curve

The US Federal Reserve's decision to hike interest rates by a quarter-point has sent shockwaves through financial markets. The move, announced by Fed Chair Kevin Warsh, was seen as a signal that more rate hikes are on the horizon, dispelling market assumptions of a one-off adjustment.

This hawkish stance led to a sharp increase in US Treasury yields, with two-year yields jumping to nearly 4.75%, their highest level since July 2024. Ten- and 30-year yields also rose to levels not seen since 2007, as investors repriced the value of benchmark government debt.

The Dollar Index surged by 1.1% on the week, its largest weekly gain in over three months, as the greenback's strength was fueled by solid US economic performance and rising short-term interest-rate expectations. The yield curve flattened significantly, with the spread between the 10-year and two-year yields dropping to about 0.24%, from a high of 0.74% earlier this year.

JPMorgan and Standard Chartered analysts noted that clear interest-rate differentials continue to support dollar appreciation, particularly against lower-yielding global currencies. Steve Englander, co-head of FX research ex-China and head of North America macro strategy at Standard Chartered Bank in New York, said 'the quarter-point hike seems to have removed one of the market's major deterrents to buying the dollar... We now see a clear path to dollar strength with 10-year Treasury yields rising to 5.5% over the next 12 months.'
