Trader consensus in the October US CPI market centers on a 0.3% monthly headline gain, carrying the highest implied probability at 40.5%, as forecasts anticipate moderation from September’s 0.6% surge. TD Securities projects a 0.30% headline and 0.21% core reading, citing mean-reversion in services, a reversal in owners’ equivalent rent after its prior spike, and softer core goods prices including used vehicles. The Cleveland Fed nowcast aligns closely at 0.25% headline and 0.21% core as of October 22. These expectations reflect partial offsets from still-elevated energy components, though gasoline volatility remains a swing factor. The data release on November 10 will resolve the contract, with outcomes clustered around 0.2–0.4% capturing over 85% of trader positioning.
