U.S. Dollar Index Rises to Nearly Eight-Week High as October Rate Hike Bets Climb to 53%
nashnova research
The dollar index touched a near eight-week high of 100.763 on Tuesday, with markets now pricing a 53% chance of another 25-bp Fed hike in October — rate expectations, not risk-off sentiment, are driving the move.
Why is the market betting the Fed keeps hiking?
LSEG data show markets expect cumulative hikes of 78 basis points by September 2027 — already beyond the Fed's own rate-path projections.
This means → the market is more hawkish than the Fed itself, essentially betting inflation proves stickier than officials forecast.
Kieran Williams, Asia FX head at Intouch Capital Markets, frames it: dollar rate support looks durable, but futures pricing has "front-run" the Fed, and the dollar now needs data to validate that bet.
Oil prices fell — why didn't the dollar follow?
Middle East tensions showed signs of easing and oil prices pulled back — normally a drag on the currency of the U.S., a net oil exporter.
Yet the strength of rate-hike expectations has more than offset the oil-price headwind, keeping the dollar on an upward path.
In plain terms = the interest-rate card outranks the oil card right now; as long as hike expectations hold, falling crude cannot pull the dollar down.
What pressure are the euro, pound, and yen each facing?
The euro traded at $1.1446, near its lowest since late July; sterling at $1.3337 — both dragged down directly by dollar strength.
The yen sat at 157.55 per dollar, with markets on alert for possible intervention by Japanese authorities.
This reflects a broad dollar-side phenomenon — euro, pound, and yen are weakening in tandem, meaning the driver is U.S. rate expectations, not idiosyncratic trouble in each counterpart.
The BOJ just hiked — so why is the yen still falling?
The Bank of Japan last week raised rates to their highest in 31 years, but the decision drew two dissenting votes and lacked a clear hawkish signal.
More critically, the Fed hiked by the same magnitude two days earlier, so the rate gap between the two countries did not narrow.
In plain terms = Japan's hike was neutralized by America's — one step up on each side, and the spread stays the same.
What is the biggest risk to the dollar staying this high?
Williams notes that 160 yen per dollar remains a risk level, but Japanese officials have reportedly stopped telegraphing intervention timing or trigger points — "the ceiling may come earlier, or in a different form."
Whether the dollar holds depends on incoming economic data validating the 78-bp tightening path the market has already priced in.
This means → if data soften, the market's front-run pricing snaps back — and that expectations gap becomes the dollar's main downside risk.
