Fed September Rate Hike Expectations Rise to 90%, Dollar Index Hits One-Year High
Alina Collins
Markets now price a 90% chance of a Fed rate hike in September, pushing the dollar index to a one-year high of 101.127 — yet an Iran oil-sanctions waiver is dragging on crude and capping the rally.
A 90% probability — what does that actually lock in?
LSEG pricing data shows traders see a 90% chance of a Fed hike in September, with one more move expected next year.
This means → the market treats September as nearly settled; the real question is how many hikes follow.
Last week's Fed meeting flagged tightening this year. Pricing snapped to match almost overnight — capital is front-running the decision.
Where is the dollar now, and why does a one-year high matter?
The DXY dollar index — a gauge of the dollar against a basket of major currencies — rose 0.1% Monday to 101.071; it hit 101.127 on Friday, a one-year peak.
In plain terms = stronger rate-hike expectations mean higher returns on holding dollars, so global capital piles in and pushes the currency up.
This reflects the single force driving FX right now: rate expectations dominate everything else.
What is holding the dollar back?
Washington granted a 60-day waiver on Iran oil sanctions, sending crude prices lower and partly offsetting the dollar's rate-driven momentum.
This means → falling oil eases inflation expectations, and cooler inflation expectations weaken the case for "must hike" — the two forces are pulling in opposite directions.
The next catalyst: whether economic data stay strong enough to sustain that 90% print. If data soften, the probability could slip fast.
