US dollar mixed after inflation report supports smaller Fed rate cut

NEW YORK (Reuters) -The U.S. dollar was mixed overall on Wednesday in choppy trading after data showed underlying inflation in the world's largest economy rose in August, reinforcing expectations that the Federal Reserve will likely implement a smaller 25-basis-point interest rate cut option next week.

The greenback posted gains against the Swiss franc, sterling, and yen, but slipped against the euro, nudging the dollar index, a measure of the U.S. unit's worth against six major currencies , 0.01% lower on the day to 101.63.

Earlier in the session, the dollar came under pressure as investors raised the chances that Democrat Vice President Kamala Harris would beat Republican rival Donald Trump in the Nov. 5 U.S. presidential election in the wake of a televised debate between the two candidates on Tuesday.

Data showed that the U.S. consumer price index (CPI) gained 0.2% last month, matching the advance in July. In the 12 months through August, the CPI advanced 2.5%, the smallest year-on-year rise since February 2021 and down from a 2.9% increase in July.

But excluding the volatile food and energy components, the CPI climbed 0.3% in August after rising 0.2% in July.

"The immediate takeaway is that this dramatically reduces the likelihood of a 50-basis-point rate cut" next week, said Ben McMillan, a principal and the chief investment officer at IDX Insights in Tampa, Florida.

"That wasn't unexpected because I thought the market was pretty aggressive at pricing in a 50-basis-point rate cut in September anyway. This reaffirms what the Fed is really focused on - the jobs numbers. This makes the jobs numbers, and the revisions to those numbers, even more important."

The "supercore" reading, which is core services excluding housing, rose 0.3% for the month, which Jefferies said was the "biggest sequential increase" since April. This brings the three-month annualized rate to 1.95% from 0.45% in the previous three months. This three-month figure rose as high as 4.18% in May and 8.16% in March, according to a Jefferies investor note.

Given the inflation data and with the Fed more likely to cut rates by 25 basis points, the U.S. dollar will possibly rebound in September before losing ground later this year and into 2025, said Vassili Serebriakov, FX strategist at UBS in New York.

"The fact that we think that the Fed will only cut 25 bps rather than 50 bps, risk sentiment looks a bit defensive and in September, we think the dollar can have a bit of a corrective bounce. Then it starts weakening again into the end of the year and then in 2025," he said.
