Markets Brace for CPI Test as Fed Eyes October Rate Cut — Evening Brief – 10.22.25 

Markets are assigning near-certainty to another Federal Reserve rate cut at the upcoming October 28–29 meeting. Fed funds futures now imply a 99% probability of a 25-basis-point reduction. Yet that conviction faces a critical test with the release of September’s Consumer Price Index (CPI) report on Friday—a data point that could either validate or complicate the Fed’s easing path. 

Consensus forecasts call for headline CPI to rise 3.1% year-over-year, the fastest pace since May 2024 and the fifth consecutive monthly increase. If realized, the number would underscore that inflation remains stubbornly above the Fed’s 2% target and could re-ignite debate over whether price pressures are reigniting amid resilient demand and tight labor markets. 

The core CPI, which excludes volatile food and energy components and is closely watched by policymakers, is expected to hold steady at 3.1%, matching August’s pace but still marking the strongest reading since February. Such a print would provide modest cover for doves inside the Fed yet keep the narrative alive that inflation’s descent has stalled. 

Economists remain divided on whether tariffs and trade policies will exert new upward pressure on consumer prices. As Ed Yardeni, president of Yardeni Research, observed, “Trump’s tariffs didn’t boost inflation but did keep it from falling to the Fed’s target of 2.0% by now.” If that dynamic persists, the Fed’s balancing act between supporting growth and maintaining credibility on price stability becomes more precarious. 

Former Treasury Secretary Lawrence Summers echoed that concern, warning that inflation risks now outweigh recession fears. “Given the strength of most categories of consumption spending, most categories of business investment, and the relatively expansionary posture of monetary and fiscal policy, I think the greater risks are on that side,” he said. 

For investors, the stakes are clear. A hotter-than-expected CPI print could force a repricing of the Fed’s easing trajectory, while a cooler-than-expected report may affirm market expectations for another cut—and potentially anchor a late-year rally in risk assets. Either way, Friday’s data may determine whether October brings another policy ease or a pause in the Fed’s fragile effort to engineer a soft landing.
