Markets are currently pricing in a near-certain outcome for the Federal Reserve's upcoming meeting, with implied odds of a rate hold sitting at 92%. However, a closer look at the latest core inflation metrics suggests this confidence may be misplaced. According to data from the Cleveland Fed, the median CPI reading rose significantly from 2.10 in August to 2.81 in September. This represents a clear acceleration in core-trend inflation that the market has yet to fully digest.

This data point introduces a meaningful risk of a hawkish surprise at the October 27-28 FOMC meeting. The Cleveland Fed's median CPI serves as a critical indicator for the central bank's disinflationary progress. An upward revision in this core metric reduces the Federal Reserve's room to maneuver, making a hold or even a hike more plausible outcomes than the current market consensus suggests.

Market pricing currently puts the probability of a 25 basis point hike at just 6%. This figure appears underpriced relative to the inflation acceleration observed in the latest prints. While a hold remains the baseline expectation, the probability of a rate hike is asymmetrically higher than the market price implies. The market is effectively paying too much for the 'maintain rate' outcome, given the renewed inflationary pressure.

What would change this read

If the October 28 FOMC statement explicitly cites significant disinflationary progress, or if the upcoming PCE and core CPI prints reverse downward below 2.5%, the probability of a rate hike would collapse. In that scenario, the market's current 92% confidence in a hold would be validated, and the 'maintain rate' contract would be correctly priced.
